oh

[wintry quarry]

you wrote IPlayerLocomotionActions

[fervent bramble]

thanks

i didn't see that

now i am getting this Assets\Adam O'Keefe\FinalCharacterControler\Scripts\PlayerLocomotionInput.cs(16,13): error CS0201: Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement

[wintry quarry]

this is all yopu copying the code incorrectly

[fervent bramble]

oh ok

[wintry quarry]

Note that this: PlayerLocomotionInput.cs(16,13) is telling you the filename, line number, and column number of where there is an issue

that's a good place to compare your code to what is in the video

[fervent bramble]

thanks

sorry i am new

Hi, I'm trying to make an object appear at mouse position (At the point a raycast hits another object),
(In a 3d, first person controlled project)
I know I need the point hit by the raycast, and to transform the object to the position (accounting for its dimensions), and to get the side the raycast hits (wich also probably implies rotating the object to match the face I'm looking at)
(Like this, https://www.youtube.com/watch?v=1ecYZXNneu0, but in first person)
I don't really have much experience on Unity and I'm trying to learn, without using AI (As it's wrong most of the time), where could I learn how to do so?

[rich adder]

what do you want to know, its pretty much done how you say it Instantiate it the raycasthit.point

[desert temple]

I'm having some trouble creating a script that just seamlessly loops the background for an endless sidescroller. Does anyone have any advice?

using UnityEngine;

public class BackgroundScroller : MonoBehaviour
{
    public Rigidbody2D rb;
    public float scrollSpeed = -2f;

    private float width;

    void Start()
    {
        // Get collider and rigidbody
        BoxCollider2D collider = GetComponent<BoxCollider2D>();
        rb = GetComponent<Rigidbody2D>();

        // Get width of the background tile
        width = collider.size.x;

        // Disable collider if it’s only used for measuring
        collider.enabled = false;
    }

    void FixedUpdate()
    {
        // Move the background left each physics frame
        Vector2 newPos = rb.position + Vector2.right * scrollSpeed * Time.fixedDeltaTime;
        rb.MovePosition(newPos);

        // Check if background has scrolled off-screen
        if (transform.position.x < -width)
        {
            // Move it to the end of the loop (seamless reposition)
            Vector2 resetPosition = new Vector2(width * 2f, 0);
            transform.position = (Vector2)transform.position + resetPosition;
        }
    }
}

I can get it moving, but the process of getting the first background to move to the second isn't working.

[cosmic dagger]

Why is the background a rigidbody?

[desert temple]

Because that's what the tutorial I was following told me to do. The script uses it too.

[cosmic dagger]

If you're only moving the GameObject and it doesn't interact with anything else, I see no reason to put a Rigidbody on it. That's all . . .

[desert temple]

Should I start with the process of scrolling in some other way?

[cosmic dagger]

When I did this, I placed a trigger collider off-screen. When the background hits the trigger, I reposition it on the other end . . .

[rich adder]

its similar code just don't need the rigidbody / physics parts
all you're doing is check a position has reached a certain treshold and put it back

[cosmic dagger]

When the first background moves to the resetPosition does it line up with the second background?

[desert temple]

I can't tell if it moves at all. Since when it moves all the way to the end of the two images, it just fails to produce anything and shows the blue screen.

I'll probably just reset everything and try a different scrolling background tutorial.

[cosmic dagger]

Blue screen? Isn't the second background that follows the first background currently in view on the screen?

[rich adder]

tbh . look at multiple ones , dont need to commit to a specific one, this way you get the overall picture/workflow you need
more important learning the concept / process of it instead of blindly copying a specific tutorial

[desert temple]

Yeah, it scrolls through the first background, and the second one, since there's two separate objects in the scene. But I'm just going to try one of the simpler methods first and come back.

[prime oriole]

Tiny thing but is there a way to use ContextMenu if the function has a parameter?

[cosmic dagger]

No, create a variable you can edit from the inspector to use as the parameter . . .

[prime oriole]

Thanks

[misty grotto]

hi im trying to change my first person camera to where i can look down and around to where i can see my shoulders with out my body turning with my camera but then if i look past that then my body turns. if you dont know what i mean, rust has this type of camera in their game. if someone can help me out or show me a tutorial that has this it would be very helpful.

[rocky canyon]

its just a regular first person camera setup..
and the arms/body/shoulders is seperate gameobject of the cam
can do em procedurally, w/ animation, or w/e

you'd just want to adjust ur clipping planes
and make sure u clamp it so u can't look too far downwards / into the model

any camera setup/script would work.. i dont have a character mesh here.. but same concept.
if u wanted to make the arms follow the camera you'd use something like unity's animation rigging package i believe

to take control of the hands/ make them follow the camera's up and down rotation

or if its only arms/hands could just parent them to the cam

[misty grotto]

i used the unity animation rigging package so that my head and top body would follow what im looking at but realized its pointless if i the body is always following the camera

[misty grotto]

what did you child the camera to? i have it as a child to the whole player for mine

[rocky canyon]

yea same..

• Root (the actual CC/Collider/Movement)
  • Camera
  • Graphics

Controller moves Left and Right (making the cam follow that axis automatically)
The camera moves Up and Down (relative to the roots rotation)

common way to do first person cams

[rocky canyon]

make the body follow the roots rotation
make the arms follow the cameras rotation
edit: ahh, i see, ya to have the body moving in one direction and the arms moving in another direction you'd end up needing to change the way the movement works
to make the camera and body seperate you'd have to change it so the player moves like a top-down controller like when left is always west and so on

-# clamp so u can't twist ur character like a pretzel

u could also have the body just twist to the direction ur moving.. (so instead of strafing ur running sideways w/ ur torso facing the cam)

but in my opinions those type of animations always look ackward to me

u'd just use ur input to change the animation rigging ik target or w/e

[misty grotto]

okay this is what my project looks like, its my first one and i know its messy. but i dont understand all the terms your using, what should i do?

[misty grotto]

that does sound like it looks akward but thats not what im going for

[rocky canyon]

ahh i see what u mean.. the camera movement doesn't allow for u to just parent the camera to the headbone gameobject for example

not sure how you'd make the camera follow along w/ the head and still have ur camera code work..
because the camera code is in control of the rotation. so the animation rigging stuff wouldn't matter to it unless it was parented beneath the head-bone
and u changed the movement code to work differently.. (maybe controlling that ik target instead?) not sure to be honest

in the scheme of things u would probably only want the camera to track the position (doing the head bobs and stuff) and ignore the rotation of the head..

it would conflict with ur mouse look code... unless u were to make the mouse code rotate relative to the head-bone's rotation which i figure would look and feel strange

and/or don't have the IK system affect the head at all.. only the shoulders and torso
ur camera code would rotate the camera and the head.. (maybe a seperate ik)

and anythings possible.. rotations can be relative or combined w/ other rotations to achieve more complex camera scripts

[misty grotto]

do you have any tutorials or terms i can search on youtube to help, im still figuring out unity and it would be very hard for me to even try what your talking about lol, either way i appreciate the help thank you.

[rocky canyon]

https://www.youtube.com/watch?v=o5HL4XKpTDg

you'd might have to change ur movemnet/camera code

[desert temple]

So. I have a scrolling background working fine, and my main controller working fine, but now I'm trying to create some random obstacles generated in the way. I'm trying to get my random objects to be generated, but so far they're not quite happening.

 private Renderer bgRenderer;

 void Start()
 {
     ResetObstacle();
 }

 // Update is called once per frame
 void Update()
 {
     bgRenderer.material.mainTextureOffset += new Vector2(speed * Time.deltaTime, 0);
 }

 void ResetObstacle()
 {
     transform.GetChild(0).localPosition = new Vector3(0, Random.Range(-3, 3), 0);
 }```
It's just supposed to create a new random object, with the asteroid childed to the background in the inspector.

[slender nymph]

i don't see any code that would create a new object here

also why are you offsetting the texture every frame instead of just moving the object?

[desert temple]

I had the texture cycling through to give the illusion of the background moving, but I think I may have figured out what I need to do.

[rocky canyon]

for obstacles u need to use real objects.. (move its transform <-) over time to match the speed of ur scrolling background.. (spawn them off to the side) can reuse them.. once they go off the other side of the screen you just reuse it and move it to the other side (can randomize where they spawn using a min-max range)

if ur scrolling a texture nothings actually moving

[near thicket]

How come I can't drag and drop the "pointsource" gameobject on the left hand side to the script's field on the right?

[misty grotto]

honestly thank you so much, you helped out a lot

[near thicket]

Incredibly dumb question I'm sorry. I was looking at the script itself and not as a component

[cosmic dagger]

You need to place the script on a GameObject in the scene. Then you can drag an in-scene GameObject (or a prefab) into the slot . . .

What you're looking at is the actual script file (asset) in the project folder. This will only set default values. If you have a prefab, you can place it as the default PointSource, but then you'd need to set it correctly when gameplay starts . . .

[near thicket]

Yes I noticed, thanks

If you are gonna post in a code channel, pls provide the code

You may added damping to the camera?

id recommend just hiding the player (deactivate it). if you provide 3rd person views too and when the player decided to switch the camera views, u can simply unhide it (activate it).

[kindred iron]

Guys, I made a state machine for my character, but the issue is that I can’t jump and walk at the same time. It’s a really big problem. I searched on YouTube — I think it’s called an advanced state machine — but unfortunately, I didn’t understand it. Can someone explain it to me easily?

[lunar axle]

i think this should be in the #🏃┃animation channel

[kindred iron]

it has nothing to do with animation but code

its a State pattern

[lunar axle]

is it animator?

[kindred iron]

no you dont use animator

its a coding pattern

the way how you code

[lunar axle]

so you control the animation based on code?

[kindred iron]

to code cleaner and more readable

[kindred iron]

no there is no animation

its a coding pattern

[naive pawn]

are jumping and walking separate states for some reason

[kindred iron]

yeah because jumping is a state too and for this problem normally people make hierarchical state machine but i cant understand it 😭

[naive pawn]

well there's your issue lol

if they're separate states, they can't happen at the same time

could just make them the same state

a state of no active action, so free movement

[kindred iron]

yeah so i asked myself how people solve this problem and they usually use hierarchical state machine for this problem

[naive pawn]

you asked yourself...?

[kindred iron]

yeah

[naive pawn]

how do you know that's the actual answer then lol

[kindred iron]

I told you that i found this on youtube and it works but i couldnt understand it

[lunar axle]

sorry bro i misunderstood u, i thought ur talkin about the animator state machine

[kindred iron]

all good ^^

[naive pawn]

you found what on youtube exactly

the state machine, or the hierarchical state machine?

[kindred iron]

can i send links here?

[naive pawn]

sure

but answer my question first

[kindred iron]

i found about 3 videos and they hierarchical state machine for this issue

1 of them is: https://www.youtube.com/watch?v=kV06GiJgFhc&t=980s

if there is another way to solve this problem then im all ears

[naive pawn]

i gave you one already

if you're a beginner, i'd say this is just overkill for getting into unity and making something to start

[kindred iron]

then it would see messy because at this point i would have to the same thing for swimming too and for swimming i would have to write walk and like eating state at the same time

[hot wadi]

Yeah, just use Animator and set trigger for jump

[kindred iron]

im coding like since 3 months

and i have experiences on roblox coding

[hot wadi]

Do u have experience with state machine in prior?

[kindred iron]

no its my first time using it with jump state

[naive pawn]

imma be real, time spent coding doesn't really say much

[kindred iron]

i coded state machine before without jump state for 2d

[hot wadi]

If u want to get into more advanced coding, u can start with what u are doing. But it's not recommended for simple movement logic.

[kindred iron]

did you say that for me or like generall my eng is not that good so i didnt understand exactly what u wanted to say

[kindred iron]

the thing is i cant never be better at coding by coding with easy and messy style

like imagine im using the easy method for that every time and i woulnt be able to better methods

[hot wadi]

Easy =/= messy. Optimization is the key

[kindred iron]

clean code is so important for me so im trying to learn with better and cleaner patterns

methods

[hot wadi]

U can write clean code without using complex methods, as long as it meets the requirement of the project

It's just readable code

[lunar axle]

sorry if im bein an idiot but for me i create functions with labels on them and each function's name generally describes its purpose. a clean code for me is less code but more on reusing the existing functions. i think thats enough, u dont need pattern machine or anythin

[naive pawn]

in general, yes. "3 months" could be expert or absolute beginner, i have no way to know

[kindred iron]

with complex methods its even better to read and these pattern are not that hard to do for something different like apple its so easy to code state machine but for character its just hard and im trying to solve this problem

[kindred iron]

i would say im beginner but not absolute beginner

[rocky canyon]

pfft.. more like 3 years u still a beginner imo 😄

[kindred iron]

for me that what you are doing is right but there is some easy patterns for more readable codes

[kindred iron]

xd

[naive pawn]

well the one you're trying to get is clearly not easy for your skill level

considering you said you're a beginner, i'd recommend just making it work before making it good

[rocky canyon]

make it work.. figure out why it works (in and out) then make it good

extra step i added there @naive pawn

[kindred iron]

Subjects are much much easier if its said correctly the way how they explain is hard to understand for me

[rocky canyon]

use multiple sources always

[kindred iron]

i can make it work normally already its easy for me so thats why im trying to code it better

[kindred iron]

yeah

i know how to make character controller like the basic stuffs

[rocky canyon]

coding better and learning good code structures/syntax/and patterns just comes from experience

like trial and error

[kindred iron]

there is not a lot of videos of this topic unfortunatly

[rocky canyon]

ya, you'll just find basic blanket tutorials

like SOLID

[lunar axle]

thats a disadvantage for u

[rocky canyon]

how u apply it is almost always relative to you and ur project

and learning how to apply it is what comes from experience

[kindred iron]

but i cant learn a pattern by doing what i know i have to try learn new things

[kindred iron]

why

if I dont try i will never be able to collect experiences then

[lunar axle]

considering u want to code it ur way but few people teaches it

[rocky canyon]

what patterns or concepts u trying to learn?

[kindred iron]

state machine. I can do it its easy for me but the issue is i cant jump and walk at the same time i cant swimm and walk at the same time i cant eat and swimm and walk at the same time you know what i mean? but normal state machine is easy to code

[eternal needle]

Movement really doesnt need to be a state machine unless this actually solves something in your system. Separating things into states when you really dont have separate states just makes things more difficult

[rocky canyon]

start with enum learn it in and out
then u can go into the more advanced state machines.. then u got ur boss level: stateless state machines

[hot wadi]

Especially if u are using animator, then u just create more overhead

[eternal needle]

It sounds like to me that you dont need a difference between walk and jump. You only need a difference between on land and on water (swimming)

A state machine by itself is a simple concept. Youre just seemingly overcomplicating it by having 2 states that really arent separate in the first place

[kindred iron]

if i dont use states when i code swimming eating walking jumping etc the code will be so messy

[rocky canyon]

messy code is part of the process 😄

1. else-if chains
2. switch statements
3. state-machine

thats how i progressed ^ atleast

[eternal needle]

Yet its clear you need to walk when jumping as per your whole issue. Eating could be separate sure if you dont allow any other action like jumping. That all depends on your design

Compare the two, either a system that doesnt work (your current setup) or a system thats messy. Which one will be playable?

[rocky canyon]

eating doesn't seem to me like it'd need to be a state..
just check the state

[kindred iron]

i experienced that already on roblox coding lol

[rocky canyon]

canEat? areswimming? Drown

[hot wadi]

"Running, walking, jumping" are all part of Moving state just to be clear

[rocky canyon]

this is me day to day ^

[kindred iron]

Then there’s no point in using this pattern. the point using this pattern is break the codes into peaces so that it wont be messy

[rocky canyon]

i just find something that i dont think is nice.. and refactor it..

and then move on.. rinse and repeat

it kinda cleans up organically

[eternal needle]

Ive already stated its possible to use this for the difference of walking and swimming. Yes its pointless if your differentiation is walking and jumping

That was one of the first things I said
#💻┃code-beginner message

[hot wadi]

The point is to optimize the calculations. Instead of checking every state condition every frame, u break them into smaller chunks to reduce the calculation.

[rocky canyon]

you can break the code into pieces many different ways.. (without even needing a statemachine) thats not really the purpose of a statemachine

[kindred iron]

the one who has bad codes but at the end of the day i wont be better at coding and i will make games slower

[rocky canyon]

a statemachines purpose is lock the thing into a single state... and run code accordingly

[rocky canyon]

gotta walk before you run mate

[eternal needle]

Really? Because right now youre stuck on an issue thats solved by not making "cleaner" code. In which case many dont consider cleaner even

The one who makes it simple seemingly makes it faster already

[rocky canyon]

ya, and also dont even think about performance until u need to

gonna shoot urself in the foot and not realize it

[hot wadi]

If u really want to pratice the concept, it's better to use for other cases like game states

[eternal needle]

Anyways I dont even think youre understanding the fact that I'm saying youre just using a state machine for the wrong purpose. Walking and jumping arent two different states if you want both working at the exact same time. Something like walking and swimming are perfectly valid as different states

[kindred iron]

yeah i get it now so but woulndt it be messy to have swimming eating moving idle etc in the same script

[kindred iron]

can you give me an example please?

[eternal needle]

Maybe reread what I'm saying. I cant make it anymore clear that swimming and walking CAN be different states

Idle wouldn't matter. Thats just moving with input of 0

[hot wadi]

For example, a game in general has Start, Playing, Paused, Win, Lose, etc.
The logic is way more decoupled

[kindred iron]

you are now saying that i should use states i guess so i shouldnt use states when i do something at the same time right? like character controller

[kindred iron]

hmm i get it ty

[rocky canyon]

a statemachine for a cc
would be like

walking / swimming / flying

when eating you'd allow that in the walking and flying state but not the swimming state for example

but eating wouldn't be a state

[eternal needle]

Yes it doesnt make sense for walking and jumping to be separate if you need them both to happen.
While walking and swimming are going to be completely unrelated code, it makes sense to split that up using states

Eating itself yea its hard to say what to do there. There are definitely designs where you could make it a state like if it slows you down, doesnt allow jumping etc

[rocky canyon]

also true..

statemachines will take a while to get good at ..
you'll get enough experience to know later on when and how to use them more properly

[hot wadi]

while (eating) defecate = false;

[kindred iron]

shouldnt i be able to walk when i swimm? but playing another animation and slower

[rocky canyon]

pfft.. watch me

[rocky canyon]

that just complicates it..

[hot wadi]

Send clip

[rocky canyon]

ewww.. lol

[hot wadi]

[kindred iron]

o-of what?

[eternal needle]

Well you'd be moving with different gravity and likely slower. The only similarity would be the method you choose to move the object

[rocky canyon]

offtopic.. dnt worry bout it just trolling

• You can’t be both Walking and Swimming at the same time — you’re in one environmental state.
• But you can be Walking and Eating — those are actions, not global states.

[kindred iron]

then i should change the state name walking something different because now it contains jump and maybe other things

[rocky canyon]

void HandleMovement()
{
    switch (currentMovement)
    {
        case MovementState.Walking:
            HandleWalking();
            break;
        case MovementState.Swimming:
            HandleSwimming();
            break;
    }
}

void HandleActions()
{
    if (isEating && currentMovement != MovementState.Swimming)
        HandleEating();
}```

heres an example.. (the states of movement are *exclusive* its either one or another.. thats when u could use a state machine)
for something like eating.. (even if it based on which state ur in it doesn't necessarily need to be part of the state handling..
u could just consider which state ur in when attempting to eat..

[rocky canyon]

Dry state, Wet state 😉

lol

[kindred iron]

Didnt understand the joke...

xd

[kindred iron]

What do you think?
What should i name it instead of walking because it contains jump

[rocky canyon]

wasn't a joke.. just silly naming..

dry state = on ground
wet state = in water

[lusty pivot]

Hi,

I would like a sprite to jump only in case it touch with ground though, it cannot jump.

Could you guys give me advices ?

I suppose the gap between BoxCollider2D and Rect tool might be one of causes.

[oak mountain]

how do I make my knockback eventually stop?

This is my knockback code, how it works is basically it just applying force onto a direction from the source (aka you the player who hit the enemy)
in the tutorial, they increased the mass of the object, and the object in the video was a cube instead of a cillinder, so maybe that could have something to do with it

using UnityEngine;

public class EntityKnockback : MonoBehaviour, IHitable
{
    private Rigidbody rb;

    private void Awake()
    {
        rb = GetComponent<Rigidbody>();
    }

    public void Execute(Transform executionSource)
    {
        KnockbackEntity(executionSource);
    }

    public void KnockbackEntity(Transform executionSource)
    {
        Vector3 dir = (transform.position - executionSource.transform.position).normalized;
        rb.AddForce (dir, ForceMode.Impulse);
    }
}

[keen dew]

Is the code AI generated? The box collider isn't involved in the ground check. Also the gizmo debug does something completely different than what the actual ground check does, and the editor doesn't even have gizmos enabled

[lusty pivot]

Yes. It is AI generated. You can ignore the gizmo debug if it has nothing to the behavior.

[keen dew]

You should consider following a course or a tutorial instead so that you'd know what your own code does

[keen dew]

The first thing to do would be to apply gravity to the enemy

[oak mountain]

I have gravity ticked off on the rigidbody because the enemy just kept falling off the map 🙏

[keen dew]

Is having it fly off the map any better? Fix the fall-off-the-map problem properly and the knockback issue solves itself

[oak mountain]

damn you right

[hot wadi]

It's basic physics

[oak mountain]

bruh the fucking gravity works now??

it doesnt fall of the map i just ticked it on

well its working now, if it aint brokey, dont fix it

😭

now another issue

since its a bean, it just falls instead of being like pushed

[hot wadi]

Make sure the Overlap position aligns with the ground. If u are not sure just use OnCollisionEnter(), OnCollisionExit() to check ground

[oak mountain]

now this is happening lol

[keen dew]

Freeze the rotation

[earnest wind]

is there some event when Time.timeScale gets changed?

[oak mountain]

wont that matter in the future when the enemies start chasing me?

cuz their animation will be all sorts of weird if they can't rotate around

[rocky canyon]

you'll still be able to rotate it w/ code and anims..

it just stops the physics from affecting it

[oak mountain]

ah gotcha, thanks

[rocky canyon]

just lock axis's that are needd

[keen dew]

You can keep the Y rotation unfrozen, X and Z are what make it tip over

[rocky canyon]

axi..

[oak mountain]

it works like I wanted it to, thanks

[hallow acorn]

hey i made a marching cube algorithm implementation and i tried interpolating it but i get this error: "Mesh '': abnormal mesh bounds - most likely it has some invalid vertices (+/-inifinity or NANs) due to errors exporting.
Mesh bounds min=(-nan(ind), -nan(ind), -inf), max=(-nan(ind), -nan(ind), -nan(ind)). Please make sure the mesh is exported without any errors.
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)"

i think it has something to do with the result of value2 - value1 as it could be 0 and i would be dividing by it. i can provide the full code if needed, heres the most important snippet:

Vector3 edgeStart = position + MarchingTable.Edges[triTableValue, 0];
                Vector3 edgeEnd = position + MarchingTable.Edges[triTableValue, 1];

                float value1 = GetDensity(edgeStart.x, edgeStart.y);
                float value2 = GetDensity(edgeEnd.x, edgeEnd.y);


                Vector3 vertex = edgeStart + (heightThreshold - value1) / (value2 - value1) * (edgeEnd - edgeStart);


                vertices.Add(vertex);

GetDensity is just providing me with my height value igenerated with my noise

[umbral pond]

should i keep my movement script in Update or FixedUpdate most tutorials i see is Update but since update called per frame would movement be diffirent on diffirent devices (faster or higher jump at better fps)

[cosmic quail]

we dont know anything about your movement script

so we can't say

[umbral pond]

its with invoke unity events new input system
rb.linearvelocity = new Vector2(moveX * moveSpeed , rb.linearvelocity.y)

this kind of script

[grand snow]

Have you used a debugger to try to catch any invalid vertex positions?

[hallow acorn]

no not really i dont really know how i would go on there

[grand snow]

Add some code to help check if something is nan and put a breakpoint so you can see what caused it.
https://learn.microsoft.com/en-us/dotnet/api/system.single.isnan?view=net-9.0
https://docs.unity3d.com/6000.2/Documentation/Manual/managed-code-debugging.html

its better to just add an if statement for such things as conditional breakpoints can slow down execution a lot

[hallow acorn]

what am i seeing bro 😭

[grand snow]

Read what i said, add some code to help find what caused nan or infinity to be produced

@hallow acorn add something like this and then attach your IDEs debugger to unity

if(Single.IsNaN(vertex.x) || Single.IsNaN(vertex.y) || Single.IsNaN(vertex.z))
{
  Debug.Log("Found NaN!");
  Debugger.Break(); //make the debugger break here without a breakpoint
}

[hallow acorn]

okay ill try that

[grand snow]

If this is confusing then you need take the time to learn about debuggers before trying to implement a complex algorithm

[naive pawn]

something like that could be in Update, though it'll really only apply once FixedUpdate happens

[cosmic quail]

i think if you're setting velocity directly then it can't be different depending on the fps

[hot wadi]

https://docs.unity3d.com/ScriptReference/Rigidbody-linearVelocity.html

They usually keep Input value in Update() and anything physics-based in FixedUpdate()

[umbral pond]

Thanks

[umbral pond]

i wanna make my player jump shorter on light tap but i still jump in same jumpForce

anyone knows solution?

[frail hawk]

#🖱️┃input-system probably

[thorn holly]

is using animator.GetStateInfo to keep track of state bad practice?

[frail hawk]

it depends

[polar acorn]

Possibly. What do you even need to "keep track of state" for

[thorn holly]

i need to know whether or not the attack animation is currently playing, bc if it is i disable the player turning around

[polar acorn]

The animator should be mostly an independent system. You should pass data to it, rather than reading from it

[thorn holly]

so like hardcode the amount of time it takes for that animation to play and set a timer?

to keep track

[polar acorn]

Or make a code based state machine and have that state machine drive the animator

[frail hawk]

or use event keys inside your animation

[thorn holly]

i did, but i still need to know when the attack finishes

[thorn holly]

unfortunately the script is on a different gameobject

[frail hawk]

still you can do that

[polar acorn]

You could use an Animation Event to signal a change in state at the end of the attack animation.

https://docs.unity3d.com/6000.2/Documentation/Manual/script-AnimationWindowEvent.html

[thorn holly]

"Use an Animation Event to call a function at a specific point in time. This function can be in any script attached to the GameObject"

its a different game object

i could use another script to bridge the gap but that feels inefficient

[frail hawk]

i´d say do what works best for you

[thorn holly]

oh wait i can just move the script 🤦

thank you

[frail hawk]

you are cross posting

[umbral pond]

which one should i remove

[frail hawk]

you were redirected to the #🖱️┃input-system

[umbral pond]

aight

can you help me tho

[hot wadi]

U should probably use a jumping bool to check if u are jumping and in the air

{
   if(isGrounded())
      jumping = true;
}```
then check for that bool in `FixedUpdate()` for jumping

[umbral pond]

ill try

[plush rampart]

Can anyone help me make a game

[tacit prism]

State machines my beloved

I’m so glad I started learning about them, they’re so fucking cool

[twilit ocean]

What do you think would be the most appropriate way to create a health/damage system for enemies in a game and why?

[rich adder]

dejavu..imo a component per char

[polar dust]

Something like health would just be a property of the enemy, unless theres a specific thing you need to do with it, nothing else should have access to the health. Its just a private property

If something directly hurts an enemy, you only need to tell that enemy how much damage you are doing. And then the enemy itself can determine whether it should be killed or not

[rich adder]

unless you use an Interface , that doesn't scale very well

[twilit ocean]

The specific reason as to why I'd want to create a health manager is as listed on the left.

[twilit ocean]

I'm still confused about which one you're talking about :V

[true pine]

what's the point of this global volume entity that ends up here whenever I create a new project? is it safe to delete it?

[rich adder]

the part keeping health variable in enemy script. If you dont have an interface, if you need to damage multiple types of things. You have to check if the thing you damaged is (a, b, c, d etc..)

an interface at least creates a "common" functions/properties they all share...say a IDamageable etc..
like, similar to a dedicated component i mentioned before..

[twilit ocean]

So you're more in favor of the left one and Hapi is in favor of the right one?

[rich adder]

I'm saying right, not sure what they meant in terms of that graph..I meant like separate components imo.. I think I suggested this yesterday, at the end of the day it's whatever is easier to you & your project needs

[twilit ocean]

So you meant to say left one wasn't scalable? How weird I thought it would be the opposite

[rich adder]

Is the right not separate scripts aka components on the same object? That's what I meant

Left could be okay too but it really depends also on the game and design

Some games use a centralized system and some let components handle their own thing

[twilit ocean]

I just thought that left one would be easier to scale up if I got the system running, like creating a new enemy would be as easy as putting some stats here and there and let the system take care of the rest instead of turning knobs for each enemy.

I don't know much of what I talked about because I'm experimenting with ideas, but it is similar to the idea of creating a centralized system that handles a general function of the game.

Just wanted to be sure it wasn't some terrible idea that a new game dev might have.

Might also be useful if I wanted to dive deeper in that function in the future?

[rich adder]

Are enemies the only thing with health / take damage ?

[twilit ocean]

No, player objects some specific projectiles and enemies all have health and take damage.

I'm not sure how I'll modify them in the future, but the current plan is that.

[rich adder]

should have these things laid out more if you want to build a system around it

If I want to Damage a Player or Bullet or Enemy, how will you tell which I can damage

hence why I suggested , using a separate component to handle that or an Interface

if you used a POCO and if they all had the same HealthStats stored you need a way to know you can access and Damage/Heal that..

[twilit ocean]

Ok in the shortest explanation possible, this basic demo will have a player character that can shoot objects of different weights, speeds and health. Damage towards enemies will be calculated by the terminal velocity in which it hits an enemy * by a preset number.

As far as health interactions go, that's it

[rich adder]

I'm not talking about the projectile damage or its calculation, I'm talking about in practical terms.. What is going to be damage, its important early on you can make this modular in case you add other items that can damage / with health..
for example, adding a Breakable box or something

[twilit ocean]

I feel like our interpretation of an interface is different. I don't know the meaning of interface in coding terminology but I heard about it before.

[rich adder]

I'll send you some info on it, basically an interface a good way to "force" certain classes to carry certain methods/ properties.. so you're always guaranteed

image you had IDamage
it has a method Damage(int amount)

in your public class Enemy : MonoBehaviour, IDamage
Like that..
Now you dont care to damage Enemy, but you care you can damage anything with the Idamageble because it has a Damage method

[twilit ocean]

Sure I'll check it out, sounds complex though so I might need some more learning before understanding how to implement that kind of stuff.

[polar dust]

public interface IEnemy {
    float Health { get; set; }
    float MaxHealth { get; }
    void Heal(float amount);
    void Damage(float amount);
}```This ensures that your Enemy would always have all of this stuff

[rancid ingot]

Any clue why an overflow occurs?

[rich adder]

what do mean "overflow"

[rich adder]

its not complex at all don't worry, they are pretty basic but very powerful to keeping your objects modular

[twilit ocean]

I'll check it out soon as I learn more

[rich adder]

https://learn.unity.com/tutorial/interfaces

[twilit ocean]

I'll try to find guides on the topic first, I don't understand much of how that works. Weird that no tutorial or guides online ever talked about that.

[rich adder]

oh there's plenty , especially on Unity

they are useful for many things besides health ofc

https://www.google.com/search?q=interfaces+unity

[polar dust]

If you did something like this, it ensures the Enemies always have a max of 100 health, and the only thing youd need to do is Enemy.Heal(5f) or Enemy.Damage(20f) there isnt so much you have to worry about, because the Enemy itself handles something like checking if it ran out of health

public class Enemy : IEnemy {
    float _hp;
    public float MaxHealth => 100f;

    public float Health {
        get {   return _hp; }
        set {   
            _hp = value;
            if( _hp <= 0f ) { Die(); }
            if( _hp >= MaxHealth ) { _hp = MaxHealth; }
        }
    }
    public void Damage(float amount) {
        _hp -= amount;        
    }
    public void Heal(float amount) {
        _hp += amount;        
    }
}

[twilit ocean]

I guess I just don't know how to search for them since I ask online unspecifc questions beginners would ask.

[polar dust]

written in notepad so it might not compile

[rancid ingot]

“overflow” means that a numeric value has exceeded the maximum (or minimum) limit that the variable type can hold, causing unexpected behavior or a crash.

[twilit ocean]

Again thanks for the code, but I need to first understand what's happening to apply that type of code.

[rich adder]

which variable are we talking about here ?

[twilit ocean]

Got it I'll search more about it

[rich adder]

gamedevbeginner.com usually has pretty decent blogs on these unity things, but theres plenty of video formats too anyway and Unitys own site I sent, though their example code is a bit gringe lol

[polar acorn]

So, what's overflowing?

[twilit ocean]

I like text because it's easier to reference and look back into

[polar dust]

a convenient thing you get for interfaces is that you can have different classes for your enemies like this

public interface IEnemy {
    float Health { get; set; }
    void Squashed();
}
// each Enemy gains a "Health" property and a "Squashed" method
class Goomba : IEnemy {
  public Health { get; set; }
  public void Squashed() {}
}
class Bowser : IEnemy { ... }
class Koopa : IEnemy { ... }```
The benefit of this is if Mario jumped on an enemy, it doesnt exactly matter what the enemy is, like whether its a Goomba. Theyre all Enemies, so Mario is able to squash any of them

[rich adder]

the major benefit is you're not relying on inheritance which can be very limiting

[twilit ocean]

That'll come useful when I understand what it means :V

[polar dust]

you could have List<IEnemy> and thats just a collection of various enemies.
otherwise you might need List<Goomba> List<Koopa> if you needed to know all the enemies in the level

[rich adder]

@twilit ocean you will lean more with all the resources out there, but just a quick example why some times "inheritance" doesnt work and interfaces are preferred ```cs
public class Character{
public virtual void TakeDamage(int amount){
Debug.Log($"Character took {amount} damage.");
}
}

public class Player : Character{
public override void TakeDamage(int amount){
Debug.Log($"Player took {amount} damage.");
}
}```

now what if we want a non-character to Take Damage?
we certainly wouldn't want a Box to inehrit Character

so we do interfaces instead

public interface IDamage {
void TakeDamage(int amount);
}

public class Player, IDamage{
    publicvoid TakeDamage(int amount){
        Debug.Log($"Player took {amount} damage.");
    }
}

public class BoxObstacle , IDamage{
    public void TakeDamage(int amount){
        Debug.Log($"Box took {amount} damage.");
    }
}```

[keen summit]

guys i have a question about lobbies, im creating this lobby system and whenever i try to join a lobby i get a null reference because my lobby code is null, is this because the lobby code is hidden outside of the lobby?

[rugged beacon]

i mean you can just change the name from character to idamageable right, they are the same,
the main different that with class inheritance you can only have one

[rich adder]

right which is the main constrain and limitations.. now you're stuck in that inheretence tree and cant inherit other things

interfaces you can have as many as you need

[twilit ocean]

As I'm reading about it in the guide it's starting to connect. I just need to learn how to actually implement it (which will come later).
Now one important question, the language in the guide I'm reading seems to hint that a project can have many interfaces with specific functions instead of few. How true is that?

[rich adder]

exactly you can have on a class as many interfaces as you need, which again is its major benefit over something like Inherence

public class Player : MonoBehavior, IHurt, ISprint, ISaveStats
etc.

[twilit ocean]

Don't interfaces aim to minimize the amount of script files created and aggregate? Why would I create a new interface for so many different interactions?

[wintry quarry]

minimize the amount of script files created

no, that is not an aim of interfaces

the aim is to reduce duplicated code for dealing with similar objects

[rich adder]

no that is never an aim for anything...
you can have many because they are kinda like a "Tag"
so different types can have the same "tag" and also the same functions

[twilit ocean]

.. But wouldn't it make sense to create a single interface file and then list all interactions there instead of creating many of them?

[rich adder]

#1390346492019212368

[rich adder]

no that would be bad to cram everything in 1 interface, especially if you have other classes that only need 1 thing from that

the requirement for interface is, whatever methods/properties are inside the class that Implements this Interface has to have defined all those methods

@twilit ocean if you had

interface IHealth{
void Damage(int amount);
void Move();
void Jump();
}```
```cs
public class Box : Monobehaviour , IHealth {
private int health = 100;
public void Jump()  { }  // why
public void Move()  { }  // why -- we are forced to implement them because they are in IHealth
public void Damage(int amount) {
health -= amount ;
}

why would you want this ?

you wont be able to just "ignore" the other things in the interface, you are forced to implement them, normally called a "forced contract"

[twilit ocean]

Ahh I see, I was expecting something similar to inheritance but cleaner, you actually need to list every single method withing a interface in order to have it work

Thought maybe we oculd somehow fetch only the specific needed method from a list that would be the interface and apply it to the desired class that needs it.

[rich adder]

not sure what you mean there tbh

the interface itself cannot and doesn't store anything

all the implementations are inside whatever class has this interface

the interface says " you should have Hurt method as a requirement, how you run and what you do inside of it is up to you in the class"

[twilit ocean]

Annd I'm confused again

Lemme read all the guide all the way before I start yapping more

[rich adder]

sure, if you have more Qs just make a thread

[worthy gale]

Howdy, I need help properly incorporating jumping into a 3D platformer, I have jump working, but Im struggling to attach the proper flags to trigger the jump->airborne->land sequence

[rich adder]

what is the exact question ? are you trying to do animation / jump through code ?

whats happening vs what you expect to happen

[worthy gale]

Ok heres my deal: I want to add proper jumping, my character can currently jump, but no animation plays. I have the logic of the animator mostly settled, my goal is to have the character jump, be able to smoothly jump on landing, and also enter a fall state if walking off a ledge thats big enough/falling, I have Landed/isJumping/isFalling bools for it, but I feel like im going in circles because I cant seem to nail it down,

my character currently freezes in the 'spiderman' midair pose until I start walking backwards/rotate when still, and break the pose back to the idle selection

[rich adder]

first I'd use blend tree to cleanup that idle / walk cycle thing.
did you check transition to self is not enabled on AnyState just incase, I typically would not use a falling from anystate but most times from movement it suffice

[rocky canyon]

i also would think blendtree's would help here

also not sure if slapping all that stuff on a any state transition will work out exactly how u wish

might want to consider re-doing the flow of that animator

[rich adder]

the only time I've used anystate tbh is like a Hurt event or something

[worthy gale]

Yeah I checked that thoroughly, and Im unfamiliar with blend trees, maybe this is too much I bit off for a basic intro game dev assignment

[rocky canyon]

ya, something quick.. that doesn't involve conditions and transitions quick and easy

[worthy gale]

I decided to use a asset store dummy with advanced animations to try and make it look good but now this is proving to be a challenge, given this is the first time Im using unity

[rich adder]

blend tree is simple, you put say.. forward,backward, run / walk and idle all in 1 spot and its just controlled by 1 float instead of going through a bunch of spider webs

[devout flint]

i know that with particle systems you can change the mode to sprites so you can select a random image out of a set list of sprites, but is there a way to select a set image based on an animator’s parameter from a list of sprites?

[rocky canyon]

yea?

[devout flint]

how then lol

[worthy gale]

the animations arent part of any grade req, so in your vetted opinion, should I focus on making the three levels we were asked, that have moving platforms/rudimentary puzzles, and just leave the jump as a jump with no animation?

[rocky canyon]

same way u'd set an animator parameter..

only u read it..

then use that to change out the image

[rich adder]

if you mean picking a specific image in a slicesheet, I know this is easier done in visual effect graph

[devout flint]

o shoot this is the scripting channel wrong spot lol

[worthy gale]

we basically have to make a 3 level platformer, with enemies/platforms, and a basic UI, and movement, and a start screen, basically a baby intro to unity

[devout flint]

i meant within the particle system itself - not any scripts >.>

ill ask elsewhere

[rocky canyon]

ya, lol!, i would have just used cubes and just rotations as animations 😄

unless "visuals" is an aspect of the grading

[rocky canyon]

no clue.. but doesn't sound like something that would be built into the particle system..

[marble hemlock]

Does anyone have any suggestions for how to do a status effect system?

Rn im thinking about using scriptable objects in a list but is it possible to hold an equation or function in a scriptable object to trigger when needed?

[rocky canyon]

good luck tho, might see u back here to script it 😄

[devout flint]

cant use scripts for this - vrchat stuff

[rocky canyon]

ohh oka

[devout flint]

asking the vrc server instead lol

[rocky canyon]

u could also ask in #✨┃vfx-and-particles if its possible to do it without scripting

[worthy gale]

I went really overkill with the animation logic to showcase my enthusiasm

[rocky canyon]

nothing wrong with that tho

if u were having fun.. roll with it

[rich adder]

you can use just about anything with this..

SOs included

[worthy gale]

this is worth like 30% of our final grade and I wasn't sure how best to demonstrate my interest, so I stapled a complicated-ish animator for a dummy off the asset store

[rocky canyon]

i would branch off of running, walking, and idle for jumping and landing and transition to anystate to return

[worthy gale]

the class assets we were given dont even have turning, jumping, or backwards walking animations, so the bar is quite low but Im not sure if thats for a base passing grade or a full 100%

basic movement, basic UI and HP, enemies that hurt you, obstacles and moving platforms, basic basic puzzle jumps, and 3 total levels

[rich adder]

what is assignment for ? isn't this overkill lol

[worthy gale]

Its a basic intro to game dev

[marble hemlock]

Its possible to call methods from scriptable objects?

[worthy gale]

I got carried away with my character animations and I wanted to make it look real good but now its becoming an issue

[marble hemlock]

I've never tried using them for anything more than basic data

Strings, int, sprites, etc.

[rich adder]

they are just classes.. unity just handles their creation as assets instead of pocos

also this is why you should keep it in 1 channel..

[grand snow]

😠

[rich adder]

yeah this is overkill already for a basic intro class lol

does it need to do jumping all that? make it a walking sim where you can interct with a button or something

[worthy gale]

Assuming I add clean sounds, and make the levels visually cool and traversable, and tweak my physics to be comfortable to play, think its worth 100%?

Yeah it needs to have jumping

but screw it, I removed it and simplified it, no jumping animation is a small sacrifice

[rich adder]

for an intro class you'd probably get 100 even if it was pong lol

aesthetic is good, but a good understanding of the basics systems is probably more than enough

[worthy gale]

it needs to be 3D, basic platformer, 3rd person

Im debating attaching cinemachine once Im done the meat to give clean camera transitions

looks simple enough

[rich adder]

yes It was more of an example i don't mean it literal

[worthy gale]

just like a pan from facing forward, to the 3rd person, and yeah lolol nw I gotcha, Im just pressed because of how open ended it is for an assignment

[rich adder]

at least I would simplify the animator a bit

well its usually based on what you learned in class, if you included all those concepts in it , you're pretty much scoring 100

if you're doing interactions, would probably score some decent points

[worthy gale]

we learned how to move with delta time, basic camera attachment and basic cinemachine stuff, and basic interactions

I plan to have a button over which you walk, and it causes platforms to drop down

for a level

[rich adder]

ya that would probably be simpler

[worthy gale]

he demonstrated some more fancier stuff but it was moreso exploratory and less assignment related because the example which he showed us in class of a finished sample game which scored full points, was pretty simple

[rich adder]

yes cause teachers got like 5-10 min a student to glance over usually

[worthy gale]

but Im still sketched so I plan to put as much possible polish before submission in 5 days

Im 100% finishing by then, the hard part of character controls and animation is done, levels will be much easier and UI and start screen should be super easy too given Im not doing anything crazy

with leftover time Il toy around with extra additions

[azure glade]

hey, can any admin look into the course Junior Programmer from Unity Learn? the videos are downloading very slow, and remain stuck if I leave them to download ahead. I don't have any networking issue, my down speed is 200

this is my options menu, it doesnt save btwn scns

it saves from the main menu to the level, but when i set it in the level and go back to the main menu it doesnt change at teh main menu

[wintry quarry]

which object is this script on? Which scene does this object live in? How do you handle the menu in your game scene?

[astral basin]

this script is on the optionsMenu gameobject, this object exists once in every scene, i handle the menu by clicking a button to open it, then the user is shown a dropdown, and some sliders to change the settings

[wintry quarry]

any errors in console at any point?

[astral basin]

no

would a video showing the problem help you visualise it

[wintry quarry]

have you done any debugging to make sure the code is actually running?

Also - is there a good reason for these variables to be static?

[astral basin]

im not sure i understand, i know it runs since it works from the main menu scene to the game scene. not vise versa though

[astral basin]

siince im new at this i wanted to first make sure the values transfer between scenes then i added the playerprefs on top of it

[wintry quarry]

yeah but "it works" is pretty vague

[astral basin]

does this help at all

everything saves except at the end where i go back to the main menu scene, where it doesnt save the changed i made in level0 scene

[wintry quarry]

honestly this video quality is pretty low so it's hard to see what you're doing.

But what I would do in your shoes is start debugging the code

add Debug.Log statements in all the places. I know for a fact there will be at least some unintentional things happening in this code

[astral basin]

yes you are right

[wintry quarry]

For example, assuming setQualityLevel() is hooked up as the value changed listener on the dorpdown (is that correct)? Then calling qualityDropdown.value = qualityLevel; in Start is actually going to cause setQualityLevel() to run too

[astral basin]

let me share what i found weird mayube you can figure it out

[astral basin]

wait thats exactly what i found weird

why does it call setqualitylevel

i dont understand

[wintry quarry]

because the value changes

[astral basin]

ohhhh

so how do i override that

[wintry quarry]

Use this instead of setting .value:
https://docs.unity3d.com/Packages/com.unity.ugui@2.0/api/UnityEngine.UI.Dropdown.html#UnityEngine_UI_Dropdown_SetValueWithoutNotify_System_Int32_****

Another issue with your code is you basically have 3 sources of truth

you have:

• The dropdown.value value
• Your static variable
• The PlayerPrefs variable

and at different tiems in your code you treat each of them as the source of truth

[astral basin]

does this just mean instead of calling a function to just put it in the update?

[wintry quarry]

For example here:
QualitySettings.SetQualityLevel(qualityDropdown.value); You use the dropdown value as the source of truth
Here:
qualityLevel = PlayerPrefs.GetInt("qualityLevel"); PlayerPrefs is the source of truth
and here:
PlayerPrefs.SetInt("qualityLevel", qualityLevel); the static var is the source of truth

[wintry quarry]

no you put the SetValueWithoutNotify call wherever you want to change the dropdown value

you only put things in Update that you want to happen every frame

[grand snow]

Doesnt TMP_Dropdown replace Dropdown now?

[wintry quarry]

yes

but their code is using the legacy one

[astral basin]

this is what im looking for right

[wintry quarry]

the same principles apply to either

[wintry quarry]

That is the documentation for the function yes

[wintry quarry]

it means instead oif qualityDropdown.value = qualityLevel; you do qualityDropdown.SetValueWithoutNotify(qualityLevel);

[astral basin]

as such?

oh i made a function for no reason but same functionality right

[wintry quarry]

there's no need for you to make an extra function yeah

but yes this is correct

[astral basin]

yeah my bad

ok let me try that

[wintry quarry]

it might not be the issue, and might not be the only issue

that's just what jumped out at me

I still recommend debugging

[astral basin]

yes ok thats one thing fixed

one other thing i noticed

i put a debuglog in the start function

but instead of being called at the start of the scene

it gets called only after i open the options menu

should i move the script to a different object thats always enabled?

its weird beacuse i read that the start function works regardless of wether the object is enabled or not

[teal viper]

You're confusing with awake

[astral basin]

so its the other way around

[teal viper]

https://docs.unity3d.com/6000.2/Documentation/Manual/execution-order.html

[astral basin]

i see

but when i set start to awake

the problem still persisted

it doesnt matter this doesnt cause any issues thanks

i figured it out thanks dlich and huge thanks to you praetorblue

[astral basin]

the fact that you saw this with your own eyes is genius bro, turns out the main issue was in the inspector lol

[marble hemlock]

Ngl i could just have it be one big script that handles all the actual effects and then have all things just contact that method. I mean I'd probably use scriptabld objects for name, description, and icon but this might be simpler than having every status effect be it's own separate thing and then try to contact all of them individually

I can't test it right now but its been haunting me the entire shift because my game kinda heavily uses status effects as a mechanic. Not a core mechanic but it influences the game pretty majorly.

Trying to look up tutorials but everyone has their own thing that perhaps im too uneducated for my brain to properly process.

[eternal needle]

If youre using scriptable objects, then it'd make sense for each scriptable object to already handle its own status effect logic through derived classes. Instead of 1 big class doing it

You need to define what a status effect is. What can it do in your game, when does it act?
Thats how you start building a system around it

[spice heart]

Hello (I'm a beginner in programming) My question is in what contexts is time.deltatime used? I've seen that they say it works with certain things and that it improves performance, but it's still not clear to me what I should use it for.

[magic slate]

Hi

[spice heart]

hi yo know about that?

[cosmic dagger]

It's commonly used when animating an object inside of Update that doesn't use the physics engine . . .

[teal viper]

Has nothing to do with performance. Delta time is just the time passed since the last frame. That's it. Any logic that needs this time, would use it.

[teal viper]

[dreamy marsh]

Hey guys i am trying to make a 2d endless side runner game and i had a question regarding my enemy spawn script

The above 2 scrensshots show how the enemies are being spawned and in theory i think the enemies should get spawned quickly so that it is challenging

but that's not the case and the eemy spawn is taking too long

the main issue starts at 15 seconds where the enemies are just so slow. Any suggestions why that is

[thorn holly]

I’m a bit confused the enemies seem to be the same speed at 15 seconds

Oh wait spawning slower?

[dreamy marsh]

so i have 3-4 enemies in the beginning that have a spawn speed of 2f so that i can give the player a tutorial

after that the spawn speed should go down to 0.2 which i dont know if it is happening

Can you post the full script

And formatted correctly

[dreamy marsh]

plus i want that the enemy spawn to be challenging - the next enemy should already be on the screen while the player is jumping over the current one bu that is not the case - there is only 1 enemy on the screen at a time

sure

done

https://paste.mod.gg/ttcxkqgchmfq/0

[thorn holly]

Is spawned being printed after the first few enemies

[sour fulcrum]

The first step to solving issues like this is something you noted yourself,

which i dont know if it is happening

Almost all problems come down to "This thing isn't happening and it should be" or "This thing is happening and it shouldn't be". You need to figure out what specifically is happening in order to determine what isn't meeting expectations

[dreamy marsh]

yes

[dreamy marsh]

yes it is being printed

[dreamy marsh]

i ran a couple of other tests and i think my corountine is working. The actual enemy spawn is defintely quicker than the initial enemy spawn

[thorn holly]

Ah I see the problem

At the top of EnemySpawnTimer you’re waiting for 3 seconds

Not sure why

[sour fulcrum]

(and waiting 2f every time you do spawn something)

[dreamy marsh]

but i still dont understand why is there just 1 enemy on the screen at a time when i theory, considering the enmy spawn rate is so quick - there should be atleast couple of enemies lined up already

[thorn holly]

Well each enemy you’re spawning takes 3.2 seconds to spawn

Because you have that wait for seconds for 3 secs at the top

[sour fulcrum]

5 seconds

[thorn holly]

That’s intentional the first few enemies they said are supposed to spawn slow

The issue is after the first few enemies spawn

[dreamy marsh]

that has been 0ed out in the editor - it was from another logic that i was testing. That variable is not being used anywhere else in the code so it should nit be added

[sour fulcrum]

they are not talking about a variable

[dreamy marsh]

that has only been implemented in the initial spawn tho?

[sour fulcrum]

yield return new WaitForSeconds(3f);

[dreamy marsh]

oh shit i see

[thorn holly]

It’s not a variable it explicitly says yield return new WaitForSeconds(3f) at the top of the coroutine

[dreamy marsh]

omg yes how did i not see that

okay let me try it out

[sour fulcrum]

In the future if you want to solve this problem independently I would

1. Add additional debug logs in all related steps that this code involves, potentially with more detailed information inside of them
2. Think about the problem more methodically. The issue is enemies are taking too long to spawn. What code here could cause that? What code here makes things wait? Narrow down the amount of suspects you need to look at

[dreamy marsh]

okay perfect - thankyou so much guys !!

[sour fulcrum]

Glad to hear it, are you open to a quick piece of feedback? No worries if your not 😄

[dreamy marsh]

sure

[wind brook]

trying to do something I feel like should be very simple, want to change the game speed when animation state of player is a certain state but it's just not working, the if statement doesn't trigger. I think it's because I'm getting the name wrong, but I've tried every possible permutation I've found and nothing seems to work

[thorn holly]

It would just be “Idle”. Also careful about checking anim state names (as I’ve learned earlier today), I would instead use an animation event instead if possible

[thorn holly]

Actually I might be wrong docs say otherwise

[sour fulcrum]

So in your EnemySpawnTimer() function you have a lot of repetitive code going on here, I point this out because it's a good example of where you can think about what here is shared between all these outcomes and what isn't

When we look at what that loop is actually doing logically, we can actually reduce that loop down to

        if (initialSpawn == false)
        {
            Enemies[] initialEnemies = new Enemies[] //This could even be a array or list you configure in editor!
            {
                Enemies[0], Enemies[0], Enemies[1], Enemies[2];
            }

            foreach (Enemies enemy in initialEnemies)
            {
                Instantiate(enemy, transform.position, transform.rotation);
                yield return new WaitForSeconds(2f);
            }

            initialSpawn = true;
        }

Furthermore, you might even want to make a little function that handles the creation of all enemies, so that way you know it's all happening the same way, like. This is just an example though 😄

    private IEnumerator SpawnEnemy(int enemyIndex, float waitTime)
    {
        yield return new WaitForSeconds(waitTime)
        Instantiate(Enemies[enemyIndex], transform.position, transform.rotation);
    }

[thorn holly]

Your best bet is prolly using an anim event, I’m sure we could figure out how to do the name thing but anim event is generally safer

[dreamy marsh]

great, i will apply both these things, thankyou!

[untold shore]

Hey - currently having a problem. Its less code, more of a general idea, but I don't know how to apply it.
Currently, I have code of npcs/ai that see the player and attack them; however, i want the enemy to be able to attack other npcs. Right now, Im having issues of thinking of how the ai enemy will see multiple groups of enemies and only attack the closest one. Im guessing it will do something with a collider, but Im not familiar enough to think about how to properly implement it.
Here is the state machine code that this will go into, particularly the function "Chasing": https://paste.ofcode.org/Cb9vQ3piFmzi52JNpVrPDx
Is there any way more experienced coders would go about this? Would they find the transform of all the npcs, then find the closest one relative to the current enemies transform? You dont have to write the code, just say general terms like "oh find the transform" or smth. Sorry, I know this is difficult to answer, so I apologize if this is confusing. If you respond, please @ me. Thanks!

[thorn holly]

Your solution is prolly the best bet yeah just tracking the transforms and comparing the distances

Raycasts would also be needed if for example walls block line of sight

[wintry quarry]

your logic is a bit overcomplicated. Why does it need to treat players and enemies differently?

[untold shore]

Mainly because of the hierarchy of enemies - I want the enemies to focus on npcs first before the player - and if both are in the same room itll disregard the player and focus on the npcs.

Also good to see you here, you helped a ton on a previous project of mine!

[wintry quarry]

I would give all of them a "threat" level and just find the highest threat level from the list of nearby things

[untold shore]

Gotcha, Ill try it out. Thank you!

[sour fulcrum]

No worries! One last thing is a tiny nitpick but is easy to get in the habit of and will really help the readability of your code,

It's worth making slight adjustments to what you name things in order for it to be more clear what it does do and also help you decide what it should do.

some examples of this

Enemies might be better as enemyTypes, enemyPrefabs or typesOfEnemies etc. Just Enemies could also refer to enemies that have been spawned or etc.

initialSpawn would be better as hasInitiallySpawned, hasInitiallySpawnedEnemies or initialSpawningComplete. Specifying the tense in the naming helps ensure you or anyone else understands what this bool specifically represents.

EnemySpawnTimer() as it's currently named to be implies the sole job of this function is to wait but currently this function is largely responsible for the actual spawning of the enemies. If your happy with this function doing the job of waiting and spawning you may want to rename it to something like SpawnEnemiesWithDelay(). It can also be worth considering that maybe you want to split this function up into smaller separate functions with specific names and tasks like EnemySpawnCooldown(), SpawnInitialEnemies() and SpawnEnemy().

You by no means have to act on any of this advice and it's certainly not critical but it's worth thinking about when your in the mood for it 😄

[dreamy marsh]

no, this is great advice - i will definitely look into it + make a note of it next time i am coding. I appreciate you taking out the time

[bright zodiac]

using timescale to slow things down is a bad practice, you're changing whole engine's timing this way, meaning unrelated stuff will be affected by it.
instead introduce your own global speed multiplier.

[untold shore]

Hey - sorry to bother you again with this. Currently Im having a little trouble with the finding the highest threat level from the list of nearest npcs. Here is how I was thinking of going about it (most likely unoptimized, but slowly getting through it:

 foreach (GameObject enemy in enemiesList)
{       
  if(sphereCollider.bounds.Contains(enemy.transform.eulerAngles))
  {
    currentEnemy = //enemy with highest level threatlevel of enemies in sphere collider
   }
}

Where would I go from there though? If i set currentEnemy = enemy in list with highest threat level, it'll go to the one with the highest threat level even if they are not inside the sphere collider. Is there another method to find a variable from a list in certain bounds?
(Please @ me if you respond. Thanks!)

[marble hemlock]

does anyone know why there seems to be some sort of delay with the testing for clicking e?

like it doesnt seem to be registering all the times i press it.

invisible cooldown...?

[teal viper]

You can't check input in a collision event. It needs to be checked in update.

[marble hemlock]

ahh i see, thank you

i should prob put a bool on like trigger enter and then tell it to check in update

[ripe shard]

You can check whether the key is pressed at any time. You just can’t reliably query the input up/down frames in physics callbacks or fixed update

[tender mirage]

Why are my rows not even, and why is there an extra 10th colum or even worse as i increase the rows it becomes extra wide

private int LevelRows = 4;
private int LevelColums = 9;

//-------------------------------------

//Start Pos
Vector3 SpawnPos = StartPos;

for (int i = 0; i < LevelColums * LevelRows; i += 1)
{
  
    //Spawn Target
    GameObject ClonedTarget = GameObject.Instantiate(TargetObject, gameObject.transform);

    //Apply offset
    ClonedTarget.transform.position = SpawnPos;




    if (SpawnPos.x < LevelRows)
    {
        SpawnPos.x += 1;
    }
    else
    {
        SpawnPos.x = StartPos.x;

        SpawnPos.y -= 0.25f;
    }



}

[grand snow]

Im going to guess that StartPos is not 0,0? what is it?

[patent wedge]

is there a transform equivalent of Rigidbody.GetPointVelocity? as seemingly the velocity is the forces applied to it rather then the current speed.

[tender mirage]

It's -5, 3.75f;

this is because my tile ratio is 16 by 4

tiles go down by -0.25f;

[keen dew]

-5 to 4 is 10 in total

as is 0 to 9

you also have rows and columns mixed up

[rocky canyon]

it'd give the velocity of a specific point on the rigidbody which includes both linear and angular motion..
(say u had a cube moving forward and spinning around its pivot.. if u used a corner of that cube you'd get both that forward velocity.. but you'd also get the angular velocity of that point, making that number greater than its normal speed you'd call it)

you might could just use rb.linearVelocity.magnitude

or u can just make ur own speed calculations

    Vector3 lastPos;
    Vector3 velocity;

    void Start() => lastPos = transform.position;

    void Update()
    {
        velocity = (transform.position - lastPos) / Time.deltaTime;
        lastPos = transform.position;
    }```

[keen dew]

That code only works by accident because the row count happens to be about half of the column count. The "standard" way to do this would be:

int LevelRows = 4;
int LevelColums = 9;

for (int x = 0; x < LevelColums; x++)
{
    for (int y = 0; y < LevelRows; y++) 
    {
        GameObject ClonedTarget = GameObject.Instantiate(TargetObject, gameObject.transform);
        ClonedTarget.transform.position = StartPos + new Vector3(x, y * -0.25f, 0);
    }
}  

[tender mirage]

I'll try to forget the code you sent me and recreate it out of my head

thank you so much

[tender mirage]

Yeah, it wasn't initially, but i messed around quite abit with it

since it was being annoying.

[keen dew]

The main thing is that don't start counting from the StartPos coordinates because they aren't really related to how many rows/columns there are in total . If the x position is -5 and total columns is 9, if you count from -5 to 9 you'll get 14 or 15

[rocky canyon]

just remember 0 is the first loop
so ur row and col count would be (desired Amount - 1)

[patent wedge]

explain using the magnitude idea.

[rocky canyon]

well velocity is the speed + direction
magnitude is just the speed

"Give me how fast this thing is moving, regardless of direction."

so if u were moving backwards at 10m/s
ur velocity would be -10 however the magnitude of that velocity would just be 10

[patent wedge]

ok when i meant speed i still meant a vector3, because i have a floating character controller that follows moving platforms using

rb.linearVelocity += hit.rigidbody.GetPointVelocity(hit.point);
```which works fine for kinematic moving platforms but if a have a rigidbody any time it changes direction its velocity at that point increases more than it should, it seemingly gets the force rather than the actual velocity at that point.

[rocky canyon]

ahh, ya you'll get higher values like that when you get forces or impulses..
it'll spike b/c it hasnt had time to settle yet (using friction, dampening etc)

if u want a smoothed velocity you should probably just track ur own velocity over time instead of using unity's raw physics output

(like that code example i sent up above)

        (currentPosition - lastPosition) / Time.fixedDeltaTime;
        lastPosition = currentPosition;```

^ if ur calculating it urself and using the Transform it'd work regardless of if its a rigidbody, kinematic, or just a transform

that would give u a Vector3 with each axis showing its speed

[patent wedge]

i've tried that but i keep getting explosive results

rb.linearVelocity += (hit.point - lastPoint) / Time.fixedDeltaTime;
lastPoint = hit.point;

[rocky canyon]

(2, 0, 1) would be moving 2 units/ second to the right and 1 unit/second forward

[rocky canyon]

this is setting the velocity..

is that the intention there?

rb.linearVelocity += a is the same thing as rb.linearVelocity = rb.linearVelocity + a

❔ let me ask this.. cuz im a bit confused..
"whats the purpose of this mechanic"
like.. whats the game-plan..

i think that will help clear it up

[patent wedge]

well when i use addforce the player is barely moved. i just want to modify the player velocity so they'll stay on the platform.

[rocky canyon]

ohhh

[rocky canyon]

you could try setting it directly using the platforms velocity
rb.linearVelocity = platformVelocity

        // you could optionally try to add some smoothing in the mix to avoid those big spikes
        pointVelocity = Vector3.Lerp(rb.linearVelocity, pointVelocity, 1f - smoothing);

        // Apply platform velocity to player (overwrites velocity, prevents explosion)
        rb.linearVelocity = pointVelocity;```

[patent wedge]

i would rather add or apply a force to the player rather than setting it as that tends to break momentum and any physicality.

[rocky canyon]

you could *grab it's velocity (without the platform) and + the platform velocity on top

that would keep w/e momentum and movement u already have going on

platforms are tricky..
(pretty simple to get them to work w/ a player that doesn't move)
but once u start walking and jumping on them.. it gets complicated

[patent wedge]

yeah i've tried that... and if that did work that wouldn't really help as you have to take into account rotation, which rigidbody.GetPointVelocity(hit.point) does.

// players existing velocity
Vector3 currentVel = rb.linearVelocity;

// platform contribution at teh contact point
Vector3 offset = hit.point - platformRigidbody.worldCenterOfMass;
Vector3 platformVel = platformRigidbody.linearVelocity + Vector3.Cross(platformRigidbody.angularVelocity, offset);

// Combine them
rb.linearVelocity = currentVel + platformVel;```

u can also make the rotation affect that platform vel u would add to the player ^

i'd have to test myself for anything more than this tho..
im just assuming it'd work but u know how assumptions go..
let me fire up my editor and see if that ^ works out on a platform..

(been putting off platforms myself for a while now)

[patent wedge]

sorry mate... but it still has the same issue with rigidbody.GetPointVelocity(hit.point) where it has strong forces when changing directions.

[rocky canyon]

ahh fudge.. sorry thats about all i got

it is super early still tho.. so my brains a bit foggy still

could u share ur code?

[patent wedge]

that's ok, thx for your help.

[rocky canyon]

the platform + player movement.. the relevant bits?

[rocky canyon]

yea im not really sure how to deal with that tbh..
you could smooth out the values like the lerp i sent up above.. but that would smooth everything.. not just the direction changes

maybe u could smooth just the direction changes somehow..

altho im not 💯 sure how

[patent wedge]

well the movement part won't effect the platform stuff as it's just adding a force to the player but for the platform code i've already shown all of it.

[real thunder]

At this point I almost gave up on this approach to make a rigidbody fps controller work, but before trying next one I would appreciate if anyone can figure out what's wrong with what I got so far, specifically:
Why is my camera stuttering only while I am strafing and turning camera around? Just strafing is smooth (rigidbody interpolation is on), just looking around while standing is smooth (also there is no friction on anything)

camera (nothing crazy, worked flawlessly with character controller basic movement, assume smoothing is 1)

void LateUpdate()
    {
        if (!isCameraLocked)
        {
            mouseinput = new Vector2(Input.GetAxis("Mouse X"), Input.GetAxis("Mouse Y"));
            mouseinput = Vector2.Scale(mouseinput, new Vector2(sensitivity, sensitivity));

            smoothdelta.x = Mathf.Lerp(smoothdelta.x, mouseinput.x, 1f / smoothing);
            smoothdelta.y = Mathf.Lerp(smoothdelta.y, mouseinput.y, 1f / smoothing);

            mouselook.x += smoothdelta.x;
            if ((mouselook.y + smoothdelta.y) > 90f)
            {
                smoothdelta.y = 90 - mouselook.y;
                mouselook.y = 90;
            }
            else if ((mouselook.y + smoothdelta.y) < -90f)
            {
                smoothdelta.y = - (90 + mouselook.y);
                mouselook.y = -90;
            }
            else
            {
                mouselook.y = mouselook.y + smoothdelta.y;
            }
            playerPosition.localRotation = Quaternion.AngleAxis(mouselook.x, playerPosition.up);
            cameraPosition.localRotation = Quaternion.AngleAxis(-mouselook.y, Vector3.right);
        }
    }

and rigidbody (shortnd)

xInput = Input.GetAxisRaw("Horizontal");
yInput = Input.GetAxisRaw("Vertical");
desiredMovementVectorNormalized = transform.TransformDirection(xInput, 0, yInput);
desiredMovementVectorNormalized = desiredMovementVectorNormalized.normalized;
Vector3 targetVelocity = desiredMovementVectorNormalized * MaxSpeed;//Set a target velocity
Vector3 velocityChange = targetVelocity - movementVector;//Find the change of velocity needed to reach target
Vector3 acceleration = velocityChange / Time.fixedDeltaTime;//Convert to acceleration, which is change of velocity over time
acceleration = Vector3.ClampMagnitude(acceleration, MaxAcceleration);//Clamp it to maximum acceleration magnitude
body.AddForce(acceleration, ForceMode.Acceleration); 

I wanted to use physics but keep perfectly controlled speed

[rocky canyon]

b/c ur player is moving with physics Fixedupdate() and your camera (that i assume is a child of the rigidbody) is being modified in Update()
these two functions don't run at teh same rate...
so u basically get sync issues

[real thunder]

player get movement forces at fixed update but turns with the camera at update through transform, would that still cause desync?

[rocky canyon]

if ur using a rigidbody doesn't matter where u call the code.. it gets applied in the FixedUpdate()

but the Camera is gonna update in Update() which happens much more often

[real thunder]

oh well...

[rocky canyon]

soo thats why u have that happen

https://discussions.unity.com/t/how-to-properly-fix-camera-and-rigidbody-stutter-jitter-lag/874587

unity learn has a tutorial that shows how they solve the camera jitter but i can't find it off-hand

[real thunder]

does charactercontroller move at update btw?

[rocky canyon]

yes

[real thunder]

now it making so much sense

[rocky canyon]

CC uses Update() b/c its a Faux Physics object

doesn't actually use physics

[real thunder]

that answers my "why" and I will find "how", thanks alot

[rocky canyon]

not a problem.. good luck 🍀 if i can find that unity learn example i'll send it ur way

[rocky canyon]

https://www.youtube.com/watch?v=cTIAhwlvW9M this might could help u out

the most common fix for it tho is

• Use LateUpdate(); for the camera logic
• Use Interpolation/smoothing for Rigidbody

also you can use Cinemachine (it has settings for changing how the camera logic works... you can set it to Update(), LateUpdate() or SmartUpdate <-- where it does magic and figures out things on its own..

Cinemachine is really useful for later on in ur game too, like to change cameras, transitions to cutscenes, camera shake, all that good stuff built in

found a thread that validates what i just mentioned
https://www.reddit.com/r/Unity3D/comments/z24l1v/how_to_fix_this_jittering_when_looking_around/

[tender mirage]

i couldn't do it myself, thanks for the script that handles it correctly.

i'll try to repeatedly write it until i remember it

[keen dew]

It'd be more useful to understand what it does instead of just memorizing it

[real thunder]

LateUpdate is still update, that would only help if I am not using phsyics, and as I said I turned on interpolation at the start and it would help with moving but not turning while moving

[rocky canyon]

https://docs.unity3d.com/2023.1/Documentation/Manual/ExecutionOrder.html
this was my point saying that..

you do turn ur character in Update() ircc
edit: or maybe u don't im thinkin of someone elses code.. but either way thats why i mentioned LateUpdate().. if it doesn't help
I still linked that Discussion's link that has multiple solutions

[real thunder]

🤔

[shell sorrel]

you want late update because without it its possible the camera runs its update, then something the camera is tracking updates after throwing it off by a frame and making it always play catch up

[real thunder]

I mean I know I want lateupdate, I missed the part saying I meant to detach camera for it to work

anyway that should work ima stitch something working

[shell sorrel]

what do you mean by detach the camera?

was it a child of your character before?

[real thunder]

yep...

[real thunder]

yep that just works and I think won't cause issues I can get from using SmoothDamp

I will have to spend some time thinking on details on WHY does it work

[edgy sinew]

Do you mean that in FixedUpdate() you have some Rigidbody code like AddForce, but then in Update() you are just doing .transform.rotation = ?

[edgy sinew]

@untold shore
Any reason to not use OnTriggerEnter and OnTriggerExit for that SphereCollider?

With that you can just keep a running list of "NearbyEnemies"
& yes no matter the method, it's unavoidable to loop through that NearbyEnemies list and check the threat level member variable

[stuck palm]

does unity have an object pooling system or will I have to make that myself?

[grand snow]

They do have an objectpool object you can use but you need to define some functions yourself:
https://docs.unity3d.com/6000.2/Documentation/ScriptReference/Pool.ObjectPool_1.html

[stuck palm]

oh nice! thank you

seems easy enough, I thought I'd have to start from scratch but this looks good

cus my game spawns a lot of hitsparks so this will alleviate it a bit

[rocky rock]

I got a character composed of different layered sprites and I want to set the whole composition transparent but going through each sprite and setting the alpha means that parts that would be hidden now become visible
any tips on how to fix this? I was thinking I should merge all the sprites together into one, but that doesn't seem so straightfoward to do

[wintry quarry]

do the merge in photoshop/gimp

[rocky rock]

not possible with all parts combinations

[wintry quarry]

what's the end goal here?

[rich adder]

but going through each sprite and setting the alpha means that parts that would be hidden now become visible
wdym?

[wintry quarry]

I think thye're basically having a blending issue. They want the fully composite image to be alpha faded but instead when you set the alpha of individual renderers you get the thing where you see all the sprites under the other sprites

[rocky rock]

having a character display with different visual parts (e.g. clothing pieces, face, hair, body, etc.) then being able to manipulate that composition with alpha masks, flipping, etc.

[rich adder]

ahhh this is like a modular character

[slender nymph]

sprite masks should help with that i would think

[wintry quarry]

one option is rendering to a RenderTexture
Another option is to use a custom shader

[rocky rock]

sprite masks might work, I think..? like, each layer applies a mask to all layers behind it? might get heavy if I got a lot of layers? 🤔

rendertexture sounds promising but I've only ever used it with Camera.targetTexture. Is there a way to directly "write" a sprite to it?

never used shaders before so no idea where I'd start on that one

[thorn holly]

When would one want to use physics.overlap box over a collider with isTrigger enabled?

[cosmic dagger]

A collider with isTrigger enabled is mainly used for checking a zone/area. You wait for something to enter or leave . . .

[wintry quarry]

when you want a direct immediate query workflow vs a reactive workflow

[thorn holly]

Do I need to consider processing power

[cosmic dagger]

If you want to check what is inside of a box at that moment in time (immediate), then you'd use an OverlapBox check . . .

[wintry quarry]

Usually not a concern

[thorn holly]

I’d imagine being forced to use a rigidbody is pretty expensive even if it’s kinematic/statoc

[thorn holly]

Oh ok sweet

[wintry quarry]

performance is almost never a concern for these decisions unless you are dealing with very large numbers of objects

[thorn holly]

Alr good to know

Thanks

[hot wadi]

Do u guys usually use a single CoroutineHandler to manage all the coroutines?

[wintry quarry]

No. To what end?

I would only do something like that if I have some special requirements

[eternal needle]

Not every trigger collider needs a rigidbody, just one of the two in an intersection needs it

[hot wadi]

I see some projects use that as a to provide helper functions that help start coroutines, ideally from other singletons
I'm not sure if that is a thing in common. Most I have seen only about few dozen lines of code

[wintry quarry]

usually they do this to ensure they have an "always active" object to run the coroutine on so they don't run into the issue where they deactivate the object running the coroutine which kills the coroutine

it could be useful to you if you are running into that issue

otherwise it doesn't add much value

[astral basin]

hi, im trying to add ads to my game and it seems to work, but when i try to build the game to test it i get this

[ivory bobcat]

This is the beginner programming channel. Try moving your question to #💻┃unity-talk

[astral basin]

ok sorry i sent here cuz im also a begginer

[real scroll]

Is this the right place to ask about Unity Learning problems for beginners?

[cosmic dagger]

For beginner coding problems? Yes. For regular Unity problems? check out #💻┃unity-talk

Also, check out the other channels if your problem fits a specific topic . . .

[real scroll]

So I am learning how to build the "Tanks" game. And when I go to my prefab>levels> and selct the levels and load it, both the preview, and the loaded level, are all pink, and do not show me the assets, just their wireframe location

Should I snip a picture for reference?

[slender nymph]

that doesn't sound like a code issue

but see this for how to go to the correct view mode: https://docs.unity3d.com/6000.2/Documentation/Manual/ViewModes.html
and this for shader issues (pink materials): https://unity.huh.how/shaders/errors

[cosmic dagger]

That usually happens when there is an issue with the materials or shaders; namely, a shader is missing or incompatible. Make sure you are using the correct render pipeline and follow the links boxfriend sent above . . .

[hot wadi]

I usually fix that in the Render Pipeline Converter since I have not done anything fancy with shader yet
But I don't know what else it changes in the project

[real scroll]

So I went to Window>Rendering>Render PipelineConvertor

And that worked. I can see my beautiful level now...

Hey! Quick question
I’m setting up my Unity project with Git for a university assignment, and I’m a bit confused about the .gitignore.

My Git repo has a subfolder for the Unity project (for example: repo/Project1/).
Should the .gitignore go in the main repo folder or inside the Unity project folder?

I saw this one from GitHub:
👉 https://github.com/github/gitignore/blob/main/Unity.gitignore

Can I just use it as is, or do I need to change anything for this setup?

[hallow acorn]

into the project folder like projectRepo/ActualProject/.gitignore

[rancid surge]

Thank you I will try it and I had some issues the first time

[real thunder]

yes I was doing that
second time I am screwing up trying to move rb through transform at Update and wondering why is it not working as expected, hopefully the last

[rancid surge]

I tried it but I still have the issue that I have 10K changes and I think its because I need to ignore the Library and stuff but It just doent work qwq
Or do I have it wrong and this totally normal?

[hallow acorn]

no thats definitely not right. tbh im not really a pro, im just searching for the unity gitignore on github desktop, put it in my project folder and it works

[slender nymph]

did you already commit the library folder before adding the gitignore?

[rancid surge]

nope the repo is empty right now

[rancid surge]

Oh so u just get he ignore from the internet and downloads the file and put it inside your project? Could it be because I use Visual Studio Code?

[keen dew]

Show another screenshot but the git tab open

[hallow acorn]

im not sure tbh, i use github desktop which automates the process a lot

[keen dew]

Show the graph at the bottom of the page

[rancid surge]

I dont have a graph there

[keen dew]

In this one click the X in the orange box so that it doesn't cover the top

[hot wadi]

Git is definitely ignoring the correct files

[slender nymph]

ideally change the view mode in the git view to organize the changes by folder then it will be more obvious where these changes are coming from and if they are from folders that should be ignored

[rancid surge]

I got a GitLab repo from my professor (it was empty — no README or anything).
I cloned it, and then I created my Unity project directly inside that repo folder.

After making a few quick changes in Unity, I opened the repo in VS Code to commit.
Then I downloaded the Unity .gitignore from this link 👉 https://github.com/github/gitignore/blob/main/Unity.gitignore
and placed it in the repo.

But even after adding the .gitignore, Git still shows around 10k changes (mostly Library, Temp etc.), which is super confusing 😅
Did I maybe put the .gitignore in the wrong place, or should I have set it up before creating the Unity project?

oh but now it says only 96 changes maybe I just needed to wait 🥲

[umbral hound]

Can anyone help me? My camera position does not reset when I stop moving, and yes, I set m_OriginalCameraPosition to m_Camera.localPosition on the first frame

public void Bob(float magnitude, float speed)
{
    if (magnitude > 0f && (PlayerInput.Instance.Horizontal() != 0f || PlayerInput.Instance.Vertical() != 0f))
    {
        m_Camera.localPosition = DOHeadBob(magnitude + speed);
    }
    else
    {
        m_Camera.localPosition = Vector3.Lerp(m_Camera.localPosition, m_OriginalCameraPosition, 0.2f);
    }
    m_CurrentCameraPosition = m_Camera.localPosition;
}

[umbral hound]

If it helps at all, the next time I move it "snaps" to the original position before starting the head bob again. Please ping me if anyone has any ideas

[slender nymph]

anyway, where is Bob being called

[hot wadi]

Where do you call this function? If it just runs in a frame then that check wont do anything

[ivory bobcat]

My camera position does not reset when I stop moving
Assuming you're referring to else not ever occurring

[umbral hound]

I call it in my own player class, and it is per frame

[umbral hound]

No, it fires, because whenever I DO move, it snaps to the original position before reinitializing the head bob

Hey guys! I'm Jaylan. I'm having a bit of trouble with my Senior Project. You see, I imported an asset called Demo City by Versatile Studio and I successfully added a day/night cycle to it. When I tried to get my spotlights to dim and brighten with my day/night cycle, I noticed that they weren't dimming at all.

I thought it was an error in my script (I have two scripts, one called TimeManager that rotates a Directional and the other called SpotlightManager), but I'm not sure if it's a coding issue. I think it has to do with the fact that the spotlights are GameObjects inside a larger GameObject called LIGHTING and that I'm struggling to connect them inside of Unity Hub.

Is someone able to assist me? I'll send over my scripts, assets, or whatever I need to as long as I'm able to figure this out.

I am having a problem with my game i have a character model with player movement and animations it is first person and the problem is that when i run or move the camera shows the back of the players head because the animation makes the player lean forward a bit when moving how can i fix this

show relevant code. also https://screenshot.help

If this isn't a code question then likely you meant to post this on a different channel.

[umbral hound]

Just remove the head

That's how AAA studios do it

[fervent bramble]

ya but i might add thrid person or make it multiplayer so there needs to be a head

[hot wadi]

Are u sure u are tracking the head?

[fervent bramble]

yes

[umbral hound]

Okay well Unity has layers. Maybe in first person, disable the head by giving it a layer, then in third person, enable the layer

[hot wadi]

Then just make it 3rd person

[fervent bramble]

i don't want to i want it to also be first person

[umbral hound]

Bro what did I do to you? I enabled syntax like you wanted

[fervent bramble]

do you know of any videos showing how to do that

[umbral hound]

I can look some up

[slender nymph]

that was not in response to you.

[umbral hound]

[polar dust]

Its a slight change, but you can tidy part of the code up

bool AllowUpdateInput {
  get {
    if( m_PlayerMovement == null ) { return false; }
    if( m_PlayerLook == null ) { return false; }
    if( m_PlayerHeadBob == null ) { return false; }
    if( m_PlayerFOV == null ) { return false; }
    return true;
  }
}

void Update() {
  UpdateInput();
}

void UpdateInput() {
  if(!AllowUpdateInput) {
    // make sure all the components exist so you are allowed to continue
    return;  
  }
  // now you dont need all the if statements inside this method
  m_PlayerMovement.UpdateMovementInput();
  m_PlayerMovement.UpdateMovement(transform);
  ...
}```

ya i see that

[hot wadi]

Double-click the error message to see which script it is. The specifies at line 16 and column 13

[fervent bramble]

ya no i fixed it with visual studio copilot and it just added the paretheses he said it needed but th escript doesn't work as intended

[hot wadi]

Yeah we do not recommend it. It can fix other stuff especially if u don’t pay attention to your code

[fervent bramble]

can someone help me fix it because i cant seem to figure out what to do

[wintry quarry]

you're missing opening and closing brackets for your second foreach statement

[fervent bramble]

oh ok so like this foreach (RaycastHit hit in hits)
{
Renderer renderer = hit.collider.renderer;
if (renderer)
renderer.enabled = true;
}

[umbral hound]

No need to ping me dude

shit

[wintry quarry]

As best practice especially for a beginner i would recommend using opening and closing brackets for all of your for and if statements, even if they're only one line.

[fervent bramble]

i was refrecing the code

[umbral hound]

Could've just copied it

[wintry quarry]

yes but with better line indentation

[fervent bramble]

dude chill

[fervent bramble]

i am so lost i can't get it to work

oh wait

nvm i think i got it

[umbral hound]

Sorry I'm just... I hate boxfriend because he told me what I needed to do, I did it, then he went "Uhm, not my problem" like wtf

[fervent bramble]

i get that that i skinda what is happening with me but don't stress it

Wait no wi get this error

"MissingComponentException: There is no 'Renderer' attached to the "[Debug Updater]" game object, but a script is trying to access it.
You probably need to add a Renderer to the game object "[Debug Updater]". Or your script needs to check if the component is attached before using it.

[umbral hound]

Add a Renderer

to the object

a mesh renderer

[fervent bramble]

how?

[polar acorn]

If by "enabled syntax" you mean "configured your IDE" they told you to do that because it's a requirement to get help here from anyone. That wasn't them volunteering to solve your problem just telling you that most people who can help would just literally ignore an unconfigured IDE

[umbral hound]

go into the inspector, there's a button that says add a component

then type in mesh renderer

[fervent bramble]

yup got it

[umbral hound]

I thought he meant enable it in pastebin

No that is what he meant

because my IDE has highlighting

[fervent bramble]

wait but should it be on the whole palyer or each of the peices i want to hide

[umbral hound]

each

[fervent bramble]

oh ok let me try

[polar acorn]

Still generally a good idea. If you want people to help you then you should make sure to make your code and question as easy to read as possible

[grand snow]

Indeed, the easier it is to read someones code its then easier to provide aid

[umbral hound]

Yeah that's what I did, and then I said "Bro, I enabled syntax, why are you ignoring me" and then he went "You're annoying". Like... why ask you to enable something if you're just gonna ignore it

I apologize for being rude but I literally have a learning disability, like... at least tell me how I'm being rude

or annoying

[fervent bramble]

i am still getting the error i don't know what to do now. Both the head and neck have mesh renderers and have the layer set to layer

[polar acorn]

Because you replied to them answering someone else and demanded they focus on you instead. Quite annoying.

[umbral hound]

You know what? Sorry for earlier. Let me try it on my own and I'll get back to you

[fervent bramble]

its okay and thank you

[fervent bramble]

or if its easier i can add you and then share my screen

[umbral hound]

Nah, I don't do well that way. Better if I just debug it on my own

[fervent bramble]

ok thanks if it is helpful the player model i am using is https://assetstore.unity.com/packages/3d/characters/humanoids/fantasy/free-low-poly-human-rpg-character-219979

Hey- current thing I’m working on from some advice yesterday.
Currently, I’m trying to find the highest value (the threat value) of an enemy who is inside a collider. Currently, I’m having trouble figuring this out as I’ve seen how to do it for ints, but not for translating this into game objects.
Here is the current script for this specifically (it’s small, but I’m on mobile currently as my desktop discord is broken)

https://paste.ofcode.org/sidxbtp8fqxR2FRCR9gciz

My main question is this: can enemycollider[].max(value) become translated into a game object, or should I attempt to do this process another way? (Please @ me when you respond, though it may take me a second to respond back due to being occupied with work, thanks!)

[dark laurel]

Better would likely be for you to manage "things" separately from colliders and threat. ie:

public class EnemyMonsterDude : MonoBehaviour
{
  public Collider HitBoxCollider;
  public int Threat;
  public string Name;
}

var enemy = _enemies.OrderByDescending(x => x.Threat).FindFirstOrDefault(y => .. is this enemy inside a collider we care about);
if (enemy != null) .. hit that enemy ..

Dunno if that makes sense, sorta pseudo-codey but might get you on the right track.

(note that I sort by threat first since that's cheap - colliders are more expensive, if you're gonna be doing it every frame or whatever)

[untold shore]

That makes so much more sense, I didn’t realize order by descending was a thing! I’ll fix up my code by that. Thank you so much!

@fervent bramble

private void Awake()
{
    for (int i = 0; i < gameObject.transform.childCount; i++)
    {
        GameObject _gameObject = gameObject.transform.GetChild(i).gameObject;
        if (_gameObject.layer == LayerMask.NameToLayer("Cube"))
        {
            Renderer renderer = _gameObject.GetComponent<Renderer>();
            if (renderer == null)
                return;
            renderer.enabled = false;
        }
    }
}

Just replace "Cube" with "Head"

Idk if the head is separate

[dark laurel]

Small nit - change return to continue or it'll stop trying to find a renderer if the first item it finds without one doesn't have one

[umbral hound]

Thanks

[grand snow]

gameObject.transform?

transform is already a property for "our" transform in a monobehaviour

[umbral hound]

yes

[grand snow]

Also id recommend only 1 use of NameToLayer() outside the loop

[fervent bramble]

do they still need to have the layer set as layer and have mesh renderer

[umbral hound]

Wdym

[fervent bramble]

does teh head need to have the layer set to the custom layer named "layer" like the old script an ddoes the head also need a mesh renderer

[umbral hound]

It has a mesh renderer, it just needs the "Head" layer

[dark laurel]

maybe simpler:

int layer = LayerMask.NameToLayer("Cube");
foreach (var renderer in transform.GetComponentInChildren<Renderer>(includeInactive: true).Where(x => x.layer == layer))
{
  renderer.enabled = false;
}

[grand snow]

Hangon, is this all to find the head in some model?

[grand snow]

for a beginner id say no this is going to confuse them

[fervent bramble]

no it i sto make teh camera not show the head bacuse durring some animations the camera shows the back of the head but it is first person

[dark laurel]

perhaps but.. fewer lines of code maybe simpler so fewer off by 1 or unrelated bugs

[grand snow]

Why not have a serialized reference already setup so you can show/hide the head without weird code to locate it layer?

[fervent bramble]

so make the layer a newlayer named "Head" and give it a mesh renderer component

[fervent bramble]

becasue i don't know how to code

[grand snow]

[SerializeField]
MeshRenderer head;

yay we can drag in the head in the editor and reference it that way

[fervent bramble]

what do you mean

[umbral hound]

The head already has a renderer

[grand snow]

You know that a MonoBehaviour can have "serialized references" where we can drag and drop things in via the inspector ui?

[fervent bramble]

wait the script hsould be attached to the whole player right or just the head

[fervent bramble]

ya

[dark laurel]

The whole player - but you can add multiple references to whatever pieces that script needs to reference

[grand snow]

Cool then we can use this to define a variable using this and drag in what we want to reference, such as the head mesh renderer

[dark laurel]

public class PlayerGuyThing : MonoBehaviour
{
  [SerializeField] private MeshRenderer Head;
  [SerializeField] private MeshRenderer Butt;
}

[fervent bramble]

thanks

[drowsy flare]

Is there a way to find all sprite renderers showing a certain sprite in unity?

[wintry quarry]

in the editor? At runtime?

[drowsy flare]

At runtime

[dark laurel]

Probably track them manually, iterating through every game object in a scene will be slow and expensive

[wintry quarry]

yes but it will be slow and inefficient and there are better ways to do what you aretrying to ultimately do

what's the actual gameplay idea here?

[fervent bramble]

so wait what should my code be because i don't see any {SrializeField} anywhere in the code

[dark laurel]

your code should look exactly like this

[drowsy flare]

It's a multiplayer game, where I have a spell casting item. All players that have certain spells equipped in different gear slots, should have something happen to that sprite.

[fervent bramble]

just that nothing else

[dark laurel]

with brackets[SerializeField] not braces and misspelled{SrializeField}

[drowsy flare]

I should probably just do it through the equipment system instead, but would be SO easy to call the sprite renderers 😛

[wintry quarry]

Ok but the sprite renderer is the presentation layer. You should deal with your actual game data to do this, not the presentation layer

[dark laurel]

putting [SerializeField] before a variable in a script makes the editor show it

[compact sandal]

Does Cinemachine still have the virtualCamera? I can't seem to find it
