var moveVector = Vector3.forward * forwardInput + Vector3.right * rightInput;
var worldVector = Camera.main.transform.TransformDirection(moveVector);

[rocky canyon]

very useful method

it basically converts ur local directions into world directions

[vapid yew]

I have two Particle System components for my weapon's muzzle flash. However in this game you're not really shooting that much.
Should I disable the particle system gameObjects when not in use for a performance boost?
I'm also wondering what resources the particle systems are drawing when they're not in play-mode.

[swift crag]

you probably then want to subtract the vertical part from that vector

you can use Vector3.ProjectOnPlane(worldVector, player.transform.up) to get rid of the vertical part

then normalize it and multiply it by the original magnitude of worldVector

so that you don't walk really slowly if the camera is pointing into the floor

[rocky canyon]

i like to use 1 particle and disable/enable it

[vast sandal]

Thats basically where I was at and why i asked for that weird vector..

Was trying to do Vector3.Scale(moveVector, inputVector)
but yeah it seems to "only" work like you're sayin

[rocky canyon]

if thats what u mean

its cheaper than destroying and instantiating

[swift crag]

this makes no sense

this is multiplying the x/y/z components of the two vectors together

[vast sandal]

Yeah i realized 😄

[vast sandal]

Yeah I had a wrong thought 😉 Ima look into what you guys proposed and check that out 🙂

[pine sun]

hello, im following a tutorial and I cant understand why there's an error ( I highlighted the "problem in VS")

!vscode

[eternal falcon]

Visual Studio Code guide

If your IDE is not underlining errors in red or autocompleting code,
please configure it using the link below:

https://on.unity.com/vscode

[vast sandal]

        movementDirection = cinemachineCamera.transform.forward * inputForward + cinemachineCamera.transform.right * inputSideways;
        movementDirection.y = 0;
        movementDirection.Normalize();
        movementVelocity = movementDirection * movementSpeed;
        playerRigidBody.linearVelocity = movementVelocity;

@swift crag @rocky canyon Tyvm!
This is what I came up with, this works 🙂
Any recommendations? Do I need a time.deltatime here? I assume no since its normalized right?

[swift crag]

Being normalized is not relevant

What is relevant is that you’re setting a velocity here. Don’t factor in deltaTime here

You use deltaTime when you’re changing something gradually over time

eg when applying gravity to change your velocity

or when applying velocity to change your position

[prisma totem]

i need some help making enemie ai i fail everytime and its getting annoying

[vast sandal]

I assume you mean acceleration here?
So time.deltatime for accelerations but this is a velocity?

[swift crag]

No. Both were written correctly — gravity is an acceleration

You’re not using your velocity to update your position here. You’re just telling the rigidbody how fast it’s going

[short tusk]

Copy that, much appreciate the clarification! 🙂

[swift crag]

Velocity times duration gives you displacement. That’s when you use deltaTime.

[vast sandal]

Yeah ik that its a acc..

Oh... I see, since im setting it to a specific velocity i DONT need deltatime here.
But as soon as its an acceleration I would need it?

[swift crag]

You’re not calculating a displacement here

[pine sun]

can someone help with this error, i cant seem to understand whats wrong

[swift crag]

If you were adding an acceleration to your velocity, yes

(Which is indeed what you’d be doing)

[vast sandal]

Aaah gotcha, because its acc * TIME (or in this case, deltatime) gotcha!

[swift crag]

Yep!

[prisma totem]

enemi ai 😦

[vast sandal]

Any other suggestion on the code? or is that otherwise "fine-ish"?^^
How would I implement that with an acceleration btw? playerRigidBody.AddForce()?

[wintry quarry]

1. You need to configure your IDE
2. You didn't name your things the same as the tutorial

[pine sun]

i just changed my IDE and I'll rewatch the tutorial but thx

[pine sun]

its actually cus i didnt save the input actions......

[languid spire]

you still need to configure your ide to get further help here

[pine sun]

i just did it a min ago

[languid spire]

screenshot your code editor

[rich adder]

old version of VS

[full hazel]

can someone help me with fixing NullReferenceException: Object reference not set to an instance of an object
enemy.Awake () (at Assets/enemy.cs:30)
pls

[languid spire]

show the code line or do we just have to guess?

[full hazel]

player = GameObject.Find("player").transform;

[rich adder]

u dont have something named player

[slender nymph]

there is no object with that name in your scene at the time that code runs

[languid spire]

so you do not have a GameObject called player

[summer stump]

https://unity.huh.how/references

[fiery breach]

may have messed up

[full hazel]

can someone help me fix "SetDestination" can only be called on an active agent that has been placed on a NavMesh.
UnityEngine.AI.NavMeshAgent:SetDestination (UnityEngine.Vector3)
enemy:AttackPlayer () (at Assets/enemy.cs:79)
enemy:Update () (at Assets/enemy.cs:43)

agent.SetDestination(transform.position);

[rich adder]

so put your agent on the navmesh

did you bake the navmesh? is it close enough to agent? is agent gameobject active ?

[gusty lotus]

Hello, I'm trying to make it a movement shooter like controller... When walking, I want to have my player gradually speed up to a target speed and then stop speeding up, but I also don't want to have a speed cap so that I am able to launch the player at higher speeds. How can I have my players stop speeding once they reach a target speed but also not use a speed cap? I'm trying to use the inbuilt force based system btw.

[rich adder]

if(vel > maxVel) return;
//capturing inputs section

[gusty lotus]

wont that mean that I wont be able to steer in the air then?

[rich adder]

its an example but just dont add onto vel

[gusty lotus]

how would I steer without adding onto the velocity

[rich adder]

only clamp the vel u got for inputs
if(vel > maxVel)
//control only steer dont add vel
else (addToVel + steer)

point being you dont have to clamp the whole rb vel or w/e

[gusty lotus]

the thing im confused about is

if I have a ton of speed

in a direction

[rich adder]

also your question was pretty vague to begin with

[gusty lotus]

okay mb

[rich adder]

no worries, just explain a little what exact mechanic are you going for

e it a movement shooter like controller..

whats that mean?

[gusty lotus]

fair enough

[rich adder]

shooters come in all sorts of genres

[gusty lotus]

basically I'm just trying to get first person movement by not directly setting the speed to a velocity

all the tutorials I looked through directly set the speed

[rich adder]

so a rigidbody controller?

[gusty lotus]

yeah

[rich adder]

so yeah addforce would work fine

you dont have to clamp the whole rigidbody velocity, you can just clamp what ur max output from input controls are

thats if you used vel

[gusty lotus]

the thing is im trying to use force

should I change to vel?

[rich adder]

both have their pros and cons

addforce is more realistic and takes a bit more fiddling to get to be "instant"

changing the forcemode is one step

but you get deceleration and stuff out the box, drag n friction

[gusty lotus]

I heard theres a forcemode for velocity

should I use that?

[gusty lotus]

ForceMode.VelocityChange

[gusty lotus]

oh damn thank you

this is really helpful

is it really hard to get friction and deceleration if I use a velocity based system

[rich adder]

you would have to probably manually lerp those values

[gusty lotus]

okay definetly not doing that

another time

thanks for the help tho

[rich adder]

np gl

[rich adder]

btw are you trying to make like speed boost or jumper ramps ?

[gusty lotus]

possibly

im trying to keep my options open for later

[rich adder]

gotcha cause thats what I assumed from "launch the player at higher speeds."

[gusty lotus]

yeah thats exactly what I was thinking

I realized if I put a speed cap it would be really hard to implement those

[rich adder]

yeah aslong as you dont do basically this
rb.velocity > maxVel
rb.velocitity = maxVel

just cap how much output your inputs can give out when speed reaches limit, just steering

[gusty lotus]

ill look into that thanks

[prisma totem]

im looking to make a zombie ai can someone help me pls

[rich adder]

ask a specific question ?

[steep rose]

there are plenty of tutorials for this

[prisma totem]

i can make him follow idk how to make a attack

[rich adder]

make a basic state

[prisma totem]

idk how to do that

[steep rose]

there are tutorials

[rich adder]

if (dist <= minDistAttack)
//attack

break down the problem into smaller ones

first you already have follow so you got your target, get the distance so you know when you want to attack and ur done

[swift crag]

hell, you can start even simpler

just make the zombie constantly attack forever

[steep rose]

lol

[swift crag]

the attack can be controlled entirely by the animator

[prisma totem]

ok thanks that could work

[swift crag]

you can use an animation event to send a message to your component

[steep rose]

how would i store a velocity and apply it when jumping as a move() command in a character controller?

air control

[rich adder]

store it in a field*

Vector3 myVel;

[steep rose]

could i store the current velocity in there but only once?

[rich adder]

yeah just make the proper conditions to do so

maybe a simple bool flag will do

[steep rose]

yeah

[rich adder]

if(velWasRecorded) return;
myVel = vel;
velWasRecorded = true;

[steep rose]

how would i apply that velocity as a movement in the mmove() command?

wait

its a vector3 so it will just take it

[rich adder]

yeah look at the type your controller expects

you IDE should hopefully be telling you

[steep rose]

yeah sorry, my brain isnt working 🥲

[strong wren]

    {
        if (Input.GetKey("mouse 0") && SP.isSpearActive == true)
        {
            UnityEngine.Debug.Log("Spear Attack");
            SpearAnimator.SetTrigger("Attack");
            Spear.GetComponent<Collider>().enabled = true;
            SP.isSpearActive = false;
        }
    }```

why is this not working?

isSpearActive is true

[swift crag]

define "not working"

does nothing get loggeD?

[strong wren]

nothiong happends

[strong wren]

nope

[swift crag]

I should point out that "mouse 0" is NOT a valid key

[cosmic dagger]

what is "mouse 0"?

[swift crag]

read the documentation for the method you are using

[strong wren]

right click

[swift crag]

https://docs.unity3d.com/ScriptReference/Input.GetKey.html

[rich adder]

use KeyCode mate

[cosmic dagger]

also, place a log at the top of the method to check that it runs . . .

[swift crag]

using KeyCode prevents bad names, yes

[cosmic dagger]

i mean, is that the correct name for it?

[rich adder]

or since its mouse you can also Input.GetMouseButton with button being index int

[strong wren]

the method lays in an update method sooo

[strong wren]

yes

well i changed ti KeyCode.mouse0 and nothing changed

same stuff

[rich adder]

cause its still wrong..

[cosmic dagger]

so what? does the method run or not?

[rich adder]

is your ide configured?

[strong wren]

yes

[rich adder]

should be capital M

[strong wren]

yes

[strong wren]

it is with a capital M

[rich adder]

mouse

[strong wren]

i just spellt it wrong

[static bay]

There's a keycode for mouse?

[rich adder]

indeed

[static bay]

I just use Input.GetMouseButtonDown(0 or 1)

[strong wren]

bro trust me it WORKS

[rich adder]

ok did you check if code runs at all with what Random suggested?

[strong wren]

putting the Debug in the method?

and not in the if statement?

[rich adder]

yes

[strong wren]

yeah then i get 1 log every frame

[rich adder]

then one of your conditions isn't true 🤷‍♂️

[strong wren]

both are tho

[rich adder]

or u dont notice log inside

[cosmic dagger]

then check that both conditions are true . . .

[strong wren]

isSpearActive is True

[rich adder]

if you got multilione && it helps to put them in a quick bool var to debug it

[rich adder]

you have to see during playmode in code

[cosmic dagger]

then you'd get a log inside the if statement . . .

[rich adder]

all that matters is what it is when the code supposed to run

[strong wren]

but im not

[rich adder]

never assume

[strong wren]

i didnt

[static bay]

It's possible that it's being set to true later. The inspector will only show the result at the end of an Update.

[rich adder]

so print both conditions

[cosmic dagger]

break them into separate if statements. you're responding with assumptions and we have no idea because you're not showing us the actual results . . .

[covert cairn]

Consider printing the status of both the mouse input and the isSpearBought to the console at runtime

If one isn't outputting what you expect, you've found what is causing the issue.

[rich adder]

bool mouseInput = Input.GetKey(KeyCode.Mouse0)
bool isSpearActive = Sp.isSpearActive
Debug.Log both

[strong wren]

wait i found smth interesting when checking if the bool isSpearActive i dont detect if the bool is true

[rich adder]

no shit

[strong wren]

true is turned on

[rich adder]

the code never lies 😏

[strong wren]

what

[swift crag]

There are two possibilities:

• You just found a compiler bug
• You made a mistake

The former is highly unlikely.

[strong wren]

sooooh

[rich adder]

also when you debug.log make sure you pass the gameObject

make sure its the same one you expect it to be

[swift crag]

Debug.Log("whatever", this);

[strong wren]

well my script is on smth else so i cant rlly grab the gameobject

[rich adder]

wdym

your script is a component, you can pass itself to see which is calling that debug with that certain value

[cosmic dagger]

it has to be on a GameObject or else it won't run . . .

[rich adder]

how else were you running Update lol

[strong wren]

i dont think yall understood me

[covert cairn]

gameObject is inherently part of every monobehavior, which your script is because it is running every frame with update

[rich adder]

also print clearer debugs

[strong wren]

i cant grab the Spear Gameobject by doing Debug.Log("whatever", this);
because i have the script on the camera

[rich adder]

mate..we need to know which script/component is running the checks

since those are the if conditions in the same code..

debugging you have to go through each possibility and check stuff off

[strong wren]

        {
            isFistActive = false;
            isSpearActive = true;
            isPistolActive = false;
            isARActive = false;
        }```

this is in another script

[rich adder]

what about it?

ur using it in the if(Sp.isSpearActive )

[strong wren]

you said smth about running the checks for the if conditions so this is how i get the true of false value for isSpearActive

[rich adder]

also doing a inventory with bools is gonna be a nightmare

[strong wren]

its not an inv

i have 4 items so

[rich adder]

alr

[strong wren]

i already did the inv

but now for no reason my spear animation stopped working

[rich adder]

yes and you need to check what the value is in the code when you try to hit the MouseButtonDown

[strong wren]

smth like this?

    {
        UnityEngine.Debug.Log(yes);
        if (Input.GetKey(KeyCode.Mouse0) && SP.isSpearActive == true)
        {
            yes = 1;
            SpearAnimator.SetTrigger("Attack");
            Spear.GetComponent<Collider>().enabled = true;
            SP.isSpearActive = false;
        }
    }```

[rich adder]

if(!Input.GetMouseButton(0))return;
Debug.Log($"{name} ready. is spear ready? {sp.isSpearActive} ", this);

if (!sp || sp.isSpearActive == false) return;
//do stuff

[rich adder]

debugging "yes" thats helpful.

try this one
#💻┃code-beginner message

[swift crag]

it's a variable

however, comma,

you need to log all of the relevant values here

[rich adder]

oh wops lol

weird naming for a var

[swift crag]

the "yes" variable, the result of Input.GetKey(KeyCode.Mouse0) and SP.isSpearActive

(i've never used GetKey for a mouse button. i wonder if that even works properly)

[strong wren]

it does

[rich adder]

usually does yea

[rich adder]

i just wanted you to put mainly this or print name in log so we know for sure its the same instance n whatnot

[rich adder]

so spear aint ready

aka not active

[strong wren]

no when spear is ready i get no return

[rich adder]

wdym by that sorry ?

[strong wren]

like when its off i get that
but when its onn i get nothing

[rich adder]

did you put anything past the return statement like another log

[strong wren]

no

nothing changed

[rich adder]

show current code rq

[strong wren]

    {
        if(!Input.GetMouseButton(0))return;
        UnityEngine.Debug.Log($"{name} ready. is spear ready? {SP.isSpearActive} ", this);

        if (!SP || SP.isSpearActive == false) return;
        UnityEngine.Debug.Log(SP.isSpearActive);
        if (Input.GetKey(KeyCode.Mouse0) && SP.isSpearActive == true)
        {
            SpearAnimator.SetTrigger("Attack");
            Spear.GetComponent<Collider>().enabled = true;
            SP.isSpearActive = false;
        }
    }

[rich adder]

if its not printing past that then its not reaching

try printing {SP.name} maybe

[strong wren]

what?

[rich adder]

are you sure you linked correct script

[strong wren]

yes

[rich adder]

idk code says false

[strong wren]

im 100% sure

[rich adder]

can you show how you set it to true

[strong wren]

since i have 2 things that rely on SP

[rich adder]

show the full context of the SpearAttack script. use https://gdl.space

[strong wren]

i just click in thru the inspector

[rich adder]

alr

[strong wren]

https://gdl.space/huwixadequ.cs
https://gdl.space/odeqirejob.cpp

pretty sure its smth with the Bool

so theres all the codes related to the spear

i removed the bool and i got this

[rich adder]

which bool?

SP.isSpearActive ?

[strong wren]

yes

[rich adder]

are you sure you don't have 2 Stats scripts in the scene?

maybe grabbed wrong one

[strong wren]

nope

only 1

[rich adder]

or setting isSpearActive anywhere else

[strong wren]

only the fist has Stats

[rich adder]

wait....

is that a scene object or the one in project prefab

ik it says scene but make sure

[strong wren]

scene

this is my sp

the thing is

   {
       if (Input.GetKey(KeyCode.Mouse0) && SP.isFistActive == true)
       {
           FistAnimator.SetTrigger("Slap");
           Slap.GetComponent<Collider>().enabled = true;
           SP.isFistActive = false;
       }
   }
```â

this code works

and its a copy and paste

[rich adder]

yeah thats weird

trying to think what it can be now.. cause its odd

feel like I'm overlooking something obvious lol

[strong wren]

me too

[sour ruin]

Hi, I've been referencing the example from the c# docs with the directions. See mine with the darker background. Normally i'd chatgpt syntax stuff but it seems to be giving the wrong answers, don't know where else to ask. FYI All the OnX methods are void returners.

[rich adder]

pretty sure void aint valid type for a switch expression

use a traditional switch

[sour ruin]

right, cool thanks

[rich adder]

the first example is an enumeration thats why it works it returns value of enum / int

[strong wren]

i just reread my code

and have no clue

[rich adder]

try resetting both scripts and relinking the references

[strong wren]

so its a bug?

[rich adder]

wait

the script was running on Fist

[strong wren]

YES SIR 🫡

[strong wren]

yes

[rich adder]

and Fist gets gameobject disabled?

[strong wren]

omg

no

[rich adder]

lol

good thing I told you to print the name, now it makes more sense idk how I didn't see the ss

[strong wren]

NOOO

omg

this is embarring

[rich adder]

it happens

[strong wren]

its cause i had a whiteblock before i 3d moddeled the hand and i just dissabld the mesh and renderer

[rich adder]

al good just remember update cannot run on disabled scripts/gameobjects

[strong wren]

ima put the Stats Script on the Camera or smth

[strong wren]

i know

[rich adder]

these types of scripts should really just be their own gameobjects

if I have an Inventory / Weapon switch script it would not be on the camera lol

[stuck palm]

just realised

nvm

hi rlly quick question about playerprefs?
if i use PlayerPrefs.SetInt(KeyName, Value); but a playerpref with the KeyName doesnt exist yet, itll just create it with the Value i give it right ?

cuz im assuming thats what it does but from what i can find its not explicitly stated

[rich adder]

yes it does

[mortal spade]

ok ty :D

[dense root]

Does setting the player overrides in the inspector and the following script accomplish the same thing?

        if (collision.gameObject.layer == LayerMask.NameToLayer("Player"))
        {
            hasEntered = false;
        }

[wintry quarry]

That code isn't doing anything related to that inspector stuff, no

the layer overrides would control whether collisions happen at all

[dense root]

Oh I see, thanks for the information.

[gusty lotus]

I have a 3d fps player controller and it always seems like it has friction applied to it while on the ground even when I have drag and angular drag set to 0. I want to stop the friction from being applied, anyone know how?

This is the material of the only thing the player is standing on

I don't have it set to anything

[wintry quarry]

The physics engine has friction

you can remove it with custom physics materials

the default material has friction

[gusty lotus]

oh damn okay

thank you 🙏

guys what's the reference name for text mesh pro button in code

private TextMeshProUGUI text; like this but for a button

[wintry quarry]

Button

[whole parcel]

do i need to import anything

[wintry quarry]

The only thing about a TMPro button is that the Text compponent in the child object is a TextMeshProUGUI.

The Button component itself is normal

[wintry quarry]

using UnityEngine.UI; naturally

Your IDE should auto suggest it for you

If it isn't doing that, you need to configure your IDE.

[jade mulch]

Hello! I'm making a 3D game played on a voxel grid. Like Minecraft basically, but on a smaller scale. Each block is a game object consisting of 6 child game objects that are planes making up a full cube. When blocks are placed next to each other, faces that are not visible to the player are not rendered by disabling the corresponding child game object.

Is this method acceptable or would it be more efficient to use a mesh renderer to render the required faces?

[remote osprey]

So I have a property in my Summon class that is closed to modification, but I want to Modificate it whenever Summon needs it.

public class Summon : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler, IDamageable
{
    public static event Action<Summon,Summon> OnSummonClash;
    public static event Action<Summon,Player> OnSummonPlayerClash;
    public Action Call;

    public CardData data { get; private set; }

The property in question is public CardData data

[wintry quarry]

This will be super inefficient

[remote osprey]

Should I just make it modifiable?

IT's always gonna be inside something that wants to mofify it

[wintry quarry]

1 GameObject per voxel is already extremely inefficient. Upping that to 7 is even worse

[jade mulch]

Hand writing a camera script makes me actually want to die

[vapid yew]

ParticleSystem fx = Instantiate(sphereParticles, transform.parent.position, Quaternion.LookRotation(transform.localRotation.eulerAngles.normalized)).GetComponentInChildren<ParticleSystem>();

I have a projectile that becomes kinematic on collision. This line instantiates a parent GameObject which has multiple children with Particle Systems.

I have set the Particle System's Simulation Space to Local and enabled Align To Direction under the shape module and yet the angle is still off!

How do I make the particle system parent GameObject flush with the collision point and have its children face forward?

[eternal needle]

which part here are you actually considering the collision point with? I just see the instantiation with the local euler angles as a direction, which doesnt really make sense. Maybe you want to use the collision normal here

[wintry quarry]

Quaternion.LookRotation(transform.localRotation.eulerAngles.normalized))
This doesn't make any sense at all

[eternal needle]

I was thinking about that real hard because I wasnt sure if it make sense 😅

[wintry quarry]

the thing to feed into LookRotation must be a direction vector

[vapid yew]

I'm really not sure tbh -- any guidance would be great.

The reason why I'm using transform.localRotation is because the projectile is placed into a parent gameObject and retains its rotation. And since the same class is instantiating the particles parent, I figure to use the same local rotation.

But I'm guessing that was a mistake 😓

[eternal needle]

did you try what i wrote above? about using the collision normal

[vapid yew]

Vector3 hit is a local method variable. I pass: col.GetContact(0).point

Wait fuck

[eternal needle]

Are you using chatgpt? I dont know how u got that from "collision normal"

[vapid yew]

I should be using otherCollider

I'm just passing through the data in a unique way. That's not the problem.

Although I do see the problem now

[eternal needle]

Honestly it looks like you're responding to something else, because I have no clue what you're saying in relation to what I said/suggest. Theres probably a good amount of context missing

Regardless, you dont wanna use the point. You want a direction, and the collision directly has the normal (aka a direction facing outwards from the object) of the surface hit

    }

Issue:
I'm having this issue where if I hold down my space bar key, my jump input gets sent multiple times before (what I assume to be true:) grounded gets set as false and it stops allowing me to do the jump input.

Intended Behavior:
I want to be able to hold down my space key so that when I hit the ground, I immediately jump again (only once), like bhopping in a source game.

The raycast should immediately return false as I begin the jump, but I have reason to believe it takes anywhere between 1-7 frames to register as false

Swap the if statements around

@fluid fossil

[fluid fossil]

I'll try that

[vapid yew]

I'm assuming when you press space you set grounded to false because that's missing also.

[fluid fossil]

yeah I just realized that was missing, it was there before and the problem still persisted. I just accidentally got rid of it before posting here

the issue still persists

it's usually not on the first jump though

it's when I'm coming back down and hitting the ground

and I assume it's because my character is actually clipping into the ground for a frame or two before realizing it's not supposed to do that

it's like a 50/50 that it'll happen when im just on the ground

but either way, even with grounded being set to false, it still douple (and even triple) jumps

[vapid yew]

Physics calcs are done separate to update

You should consider using an overload with a LayerMask. Editing your projects physics settings will allow you to refine your physics calls also.

Physics.CheckSphere(groundCheck.position, .5f, groundMasks) && !isPlayingSFX && !isGrounded)

[charred spoke]

Physics raycast is not tied to fix update however it happens when you call it

[vapid yew]

This is what I use for my FPS controller and it works like a charm

In this case for context:

groundMasks = LayerMask.GetMask("Ground", "Lava", "Water");

You're shooting a single ray from your transform.forward. A more accurate and realistic grounding detection would be Physics.CheckSphere or Physics.OverlapSphere

OverlapSphere may return an array of Colliders.

Whereas CheckSphere does not.

[ruby python]

Mornin' all. I'm continuing on my learning SO journey and trying to figure out the 'best' way of doing things.

Currently I'm planning on different weapon types (Projectile/Laser/FlameThrower etc.)

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.VFX;
using MoreMountains.Feedbacks;

public class PlayerPrimaryWeapon : ScriptableObject
{
    public Text weaponName;
    public GameObject bulletPool;
    public int numberOfShots;

    public Transform firingPointLeft;
    public Transform firingPointRight;

    public MMF_Player leftArm;
    public MMF_Player rightArm;

    public VisualEffect weaponMuzzleFlashLeft;
    public VisualEffect weaponMuzzleFlashRight;

    public float firingRateMultiplier;
    public bool isDualWeild;

    public AudioSource weaponSound;
    public float volumeMultiplier;
}

This is my current SO setup, obviously this is essentially just for the projectile type weapon. I was wondering if anyone had any pointers in terms of adding/adjusting this to be able to deal with all weapon types.

Ideally I'd like to use a single 'one size fits all' SO and 'Shooting Script'

This is my current shooting script (hasn't been updated to make use of the SO as yet)

https://hastebin.com/share/oyewaloyaj.csharp

[rich egret]

yoooo

    {
        Vector3 targetLocalPosition = playerCamera.transform.TransformPoint(playerCameraRootPosition);
        transform.localPosition = Vector3.Lerp(transform.localPosition, targetLocalPosition, Time.deltaTime * 5f);
    }```

It's part of a weapon code, the code is meant to make the weapon be in the same position relative to the camera, but it doesn't work well...

[storm pine]

If you want it to be in the same position relative to the camera why just don't set the weapon as a child of the camera on the Start()? This will be also more efficient that calculating and updating the position frequently.
Also if you want on Update, localPosition is to change the position of the object relative to the parent and transform.position if you want to move it on the worldspace.
You maybe need this also to make sure your Camera position is updated when you do the update of the weapon: https://docs.unity3d.com/ScriptReference/MonoBehaviour.LateUpdate.html
Anyways, I still think the best option is to set the weapon as a child of the camera

[ruby python]

Hi again all,

So I've reworked my Weapon SO a bit and have got some Inheritance built in, but I'm struggling with how to get an Enum value out of the SO in my weapon firing script......

'Base' SO with the Enum.

using UnityEngine;
using UnityEngine.UI;

public class PlayerPrimaryWeapon : ScriptableObject
{
    [Header("Base Stats")]
    public string weaponName;
    public Text txtWeaponName;
    public bool isDualWeild;
    public Transform firingPointLeft;
    public Transform firingPointRight;
    public AudioSource weaponSound;
    public float volumeMultiplier;
    public enum weaponType
    {
        Projectile,
        Laser,
        Flamethrower
    }
}

What I'm trying to do is use the Enum value to control a Switch/Case in my shooting script, but can't seem to figure out how to get the value out.

Anyone have any pointers please?

[cosmic dagger]

just access the enum variable . . .

[ruby python]

That's where I'm struggling, 'weaponType' doesn't show up as an 'acceptable' variable.

Oh hang on. Do I need to do

playerPrimaryWeapon.weaponType.Projectile (etc) as the 'cases'

[cosmic dagger]

oh, weaponType is an enum. you need to create a variable of weaponType in your SO . . .

using UnityEngine;
using UnityEngine.UI;

public class PlayerPrimaryWeapon : ScriptableObject
{
    public enum WeaponType // Enum declaration
    {
        Projectile,
        Laser,
        Flamethrower
    }

    [Header("Base Stats")]
    public string weaponName;
    public Text txtWeaponName;
    public bool isDualWeild;
    public Transform firingPointLeft;
    public Transform firingPointRight;
    public AudioSource weaponSound;
    public float volumeMultiplier;
    public WeaponType weaponType; // Variable declaration
}

[ruby python]

Aaaah, I gotcha, thank you 🙂

[cosmic dagger]

notice how i capitalized WeaponType to differentiate from the enum and variable . . .

[ruby python]

Yeah that makes sense when seeing it 'written out' 🙂

[cosmic dagger]

a bit picky, but i'd change txtWeaponName to weaponText. also, you should use Text Mesh Pro text instead of the legacy Text component . . .

[ruby python]

Yeah, there are some things I want to change. tbh, I've never used TMPro, seems overkill for what I need tbh. But yeah the txtWeaponName is just a force of habit thing left over from my college VisualBasic days. lol.

[cosmic dagger]

yes, since WeaponType was created inside of PlayerPrimaryWeapon . . .

[cosmic dagger]

don't worry, it's not overkill. it's the default and new (not anymore) way to use text. that's why the package comes pre-installed. every thing about it is better than legacy text . . .

[ruby python]

Yeah, it's just a 'what I'm used to' thing really, atm I'm just trying to learn the ins and outs of SO's. I haven't even 'built' the UI yet. lol.

[cosmic dagger]

they're great to use. just make sure not to modify their values. basically, they're read-only c# classes that you can edit in unity . . .

[ruby python]

Yeah, I know that part, and am finally understanding why they're beneficial. 🙂

[ivory bobcat]

You'd practically just reference the tmpro, ui or text and do the same thing you'd do with regular ui text. https://docs.unity3d.com/Packages/com.unity.textmeshpro@1.0/api/TMPro.TMP_Text.html
The main difference would be having higher resolution text (old school text can be blurry) and some added features of tmpro which you can ignore.

[chrome shadow]

If i want to write a code that can increase a value but the speed it increases by also increases over time?

Like initially it starts off slow but after a few seconds it increases really fast

still new to coding and im not sure how to do this

😅

[ruby python]

This might be really stupid, but what should I be referencing for the 'cases'?

        switch(playerPrimaryWeapon.weaponType)
        {
            case playerPrimaryWeapon.weaponType.Projectile:
                // Do things here
                break;

            case playerPrimaryWeapon.weaponType.Projectile:
                //Do things here
                break;
            default:
                //Default Stuff Here
                break;

        }

The current 'cases' are just broken/not recognised, so not really sure what I should be referencing. 🫣

[cosmic dagger]

just be careful or you'll end up down the rabbit hole; creating pluggable methods (actions) with SOs and every script being runfrom an SO . . . 😅

[ruby python]

Okay thanks 🙂 Will have a look once I have SO's sorted in my brain. lol.

[cosmic dagger]

each case will be each of your enum values . . .

[ivory bobcat]

I see a question mark but I'm not quite understanding the question. Yes you can write code to increase a value over time. Yes, you can implement it using a variable rate.

[chrome shadow]

yeah mb like i want Value A to increase over time but the rate it increases by also increases over time
so basically the speed it increases by gets faster

[ruby python]

Hmmm.......I'm doing something wrong somewhere as none of the values are showing up in the 'autocomplete' box 😕

[eternal needle]

How are you increasing the value in the first place?

[chrome shadow]

uhhh thats kinda my question

[cosmic dagger]

each case should be from the actual enum type, not the instance:

case PlayerPrimaryWeapon.WeaponType.Projectile```notice i'm accessing the type, not the instance . . .

[chrome shadow]

im not sure how to do this idea

part

[ruby python]

Yeah, literally just figured that out. lol. Thank you 🙂

[eternal needle]

Your question is about changing how often a value is increased. Surely you have a value that is already being increased if you ask this

[ivory bobcat]

Maybe you should show what you've tried and explain where you've gotten stuck.

[eternal needle]

Regardless youd just keep track in update how long it's been, a simple timer using time.deltaTime. compare that to some value (how long it should be between increases). Change that value as needed

[chrome shadow]

sorry mb

is this correct

[ruby python]

Okay, sorry to be annoying, but in general, this should work right? (I haven't modified the shooting script to use the data from the SO yet beyond the Enum.)

https://hastebin.com/share/isugucucim.java

[eternal needle]

Does it work? We also cant even see the whole delay between increases part, which is the whole question

Ideally you would use Update for this

[chrome shadow]

it doesnt

[eternal needle]

Then clearly it's not correct

[ruby python]

I'm using a simple timer in this code.

Have a look and you should be able to figure it out.

[chrome shadow]

thanks for the tip

[cosmic dagger]

looks fine to me, though there are spots you can refactor to reduce code repetition. i'd place the code within each case in a separate method. much easier to read and tweak, if necessary. does it work when testing?

[ruby python]

I haven't tested as yet, need to rework some of the code before doing that. And yeah I know I can refactor the methods where I'm switching hands into one method. I like to work 'verbose' when figuring things out and then refactor.

Okay, well I just ran it and no errors throw up and it fires. So yeah the switch is working, which is awesome. 🙂

[cosmic dagger]

Sweet! Definitely test after making small changes. If you wait too long and change or create a lot of code, it'll be harder to debug . . .

[ruby python]

Oh yeah I know. lol.

[ruby python]

Thank you for the help, really appreciate it 🙂

[cosmic dagger]

No problem. I don't do much myself, but it's easier to help others . . .

[silver flicker]

Hey, making a 2d platformer with circular objects that have to roll, and i need the movement snappy. After using rb.AddForce(), the first contact and first movement is great, but after letting go of all the keys the object keeps moving for a long time. Is there any way around this?

[naive pawn]

increase angular drag/drag on rigidbody, or friction on the materials, maybe

[silver flicker]

So another small question, I adjusted the friction on the physics materials for both the ground and the player object, but neither made much of a difference.

[naive pawn]

i mean, it is rolling instead of sliding

[silver flicker]

(And both at the same time)

Yeah, I was hoping itd still work

[naive pawn]

friction doesn't make much difference for rolling

that's how rolling works

[silver flicker]

Angular drag rlly doesnt change much either, I'd have to increase the speed and then increase the drag forever

Would any other movement methods work better?

[naive pawn]

drag is proportional to velocity squared, so i don't think scaling should be too much of a problem

i mean, if you're looking to make it realistic to physics, then you would just have to get the parameters realistic

[silver flicker]

Im not exactly looking for realism tbh, but I'm just unsure on which movement methods would benefit me the most. I need the rolling effect and the gravity scale

this is my code - https://gdl.space/fuqaqatifi.cs

[naive pawn]

i don't mean realistic realistic, im just referring to the physics of the objects being believable

just physics being realistic

[silver flicker]

Yeah, I need that, but i need a fast deceleration after adding the force which I cant quite work out

If I were to increase the angular drag, it slows down my playerobj. That means that I would have to increase the speed which causes the same problem

Would linear drag apply to a rolling object?

[naive pawn]

yes, it's moving linearly

[naive pawn]

you're not applying a torque though, actually? you're applying a linear force

[silver flicker]

No, not applying a torque

I think I'm getting somewhere with the linear drag

Now I'm gonna have a battle with the stiffness

[naive pawn]

i think you would have to use the same drag as the force you're applying

so linear drag for linear force

[silver flicker]

Ok, and increase the gravity then?

[naive pawn]

is your jumping too floaty or something?

[silver flicker]

Well it falls rlly slowly

When I increase the drag

[naive pawn]

oh hm

yeah that makes sense

i can't think of anything definitely clean for that

maybe have a go at torque + angular drag?

[silver flicker]

Ok, I'll check the drawbacks of adding torque tho, might interfere with a load of other things

thanks tho

[lavish dove]

I wonder if anyone can help I have a very strange issue. I have a corountine that tweens this ball from one point to the next, but after the first point it shoots off into a different direction and the code is no longer called anymore.

    public IEnumerator MoveObjectAtTime(float timeOfArrival, Vector3 target)
    {
        float duration = timeOfArrival - Time.time;
        float distance = Vector3.Distance(transform.position, target);
        float speed = distance / duration;
 
        while (transform.position.x != target.x && transform.position.y != target.y)
        {
            //Not sure about the Time.deltaTime, maybe try without and tweak it to see what results you get
            transform.position = Vector3.MoveTowards(transform.position, target, speed*Time.deltaTime);
            //wait for the frame to finish calculating
            yield return null;
        }
 
        //stops the coroutine
        Invoke("BeginNextFlightPath", 1.0f);
        StopCoroutine(flightPathCoroutine);
        // yield break;
    }

[naive pawn]

if the coroutine stops, is it maybe just bouncing off with physics?

[lavish dove]

There's nothing to bounce off. I'm thinking it might be how MoveTowards works, but in the documentation nothing explains why that would happen.

[lethal bolt]

Why dosent the player touch the Ground. When its easy to see it does?

[lavish dove]

With an explicit call to a target location with a call target location it does go to the right place, then predictably it crashes because it's an infinite loop in the code.

[lavish dove]

I think I see the problem
while (transform.position.x != target.x && transform.position.y != target.y)
Both the values need to no equal the target x or y, otherwise it skips over it, causing weird issues.

[naive pawn]

so || that i guess?

or you could compare the entire vector

[lavish dove]

Tried || that then goes into a different direction.

I'll try comparing the two vectors.

[naive pawn]

that should be same as comparing != || !=

[lavish dove]

Interestingly it always goes in the opposite direction after the first step.

[naive pawn]

gonna need a bit more info to go off of here

[hoary ice]

im using float x - delta time as a cooldown
but i feel like its not working inside a while loop

when i put it outside the while loop its working fine
am i missing something?

[naive pawn]

while is blocking, time doesn't progress while you're inside the while (unless it's with a coroutine)

how exactly are you using it?

[lavish dove]

It's in a coroutine.

    public IEnumerator MoveObjectAtTime(float timeOfArrival, Vector3 target)
    {
        float duration = timeOfArrival - Time.time;
        float distance = Vector3.Distance(transform.position, target);
        float speed = distance / duration;
 
        while (transform.position.x != target.x && transform.position.y != target.y)
        {
            //Not sure about the Time.deltaTime, maybe try without and tweak it to see what results you get
            transform.position = Vector3.MoveTowards(transform.position, target, speed*Time.deltaTime);
            //wait for the frame to finish calculating
            yield return null;
        }
 
        //stops the coroutine
        Invoke("BeginNextFlightPath", 1.0f);
        StopCoroutine(flightPathCoroutine);
        // yield break;
    }

[naive pawn]

uh that was in response to the other guy

[hoary ice]

while enemy hp > 0 player will attack then applies cooldown inside the while loop

[naive pawn]

hey actually why is that in a coroutine? if you're trying to do it per frame, why not just put that in Update

[hoary ice]

i tried applying coroutine and its not working

[naive pawn]

yeah, how exactly are you implementing that

[hoary ice]

damn i cant show you the code cause im using visual scripting

[naive pawn]

why not

just screenshot it

[hoary ice]

okay wait

subgraph attackcooldown is just basically attack - deltatime

[naive pawn]

what are the if/while conditions

[lavish dove]

I'm doing it as a corotine because I need to iterate through an array of position for the path of the ball.

[naive pawn]

i don't see how that relates to it being a coroutine

[storm pine]

Use the distance value as a statement on the while loop. While(distance > 0.02){
//Recalculate distante
}
It so hard that an object achieve a specific position

[hoary ice]

maybe i just need to use the wait node with coroutine instead of minus delta time right?

[naive pawn]

maybe, no clue what you're trying to achieve

you probably need to set state instead of trying to do everything in a single pass

[storm pine]

Also you will be maybe interested on a tween engine, like LeanTween, that automatic made the process of animation with a specific ease in case you need it

[broken cargo]

using direct comparison while also using Vector3.MoveTowards is fine because of MoveTowards implementation

[storm pine]

Ah, good to know

[hoary ice]

im using state machine already

[naive pawn]

are you using it for "can attack" though?

[hoary ice]

ooh good point

ill implement

but does wait for seconds work inside a while loop?

[naive pawn]

no, it needs to be in a coroutine

im not sure how exactly visual scripting works, but i'd guess that you don't need the while at all

there's already a loop, going on every frame

your code would be running on that loop already

you can only attack once per frame, so you would just use an if instead

[hoary ice]

okay im getting your point

[naive pawn]

so, if there's an enemy this frame, and you can attack, attack

now the problem is in "you can attack", how would you check for that
that's where you need the timer

[lavish dove]

That causes it to stop in place.
float duration = timeOfArrival - Time.time; I'm starting to think maybe the time extended duration over time might be the issue.

[naive pawn]

you could use a coroutine to set "can attack" back on after a delay, or you could use your original apprach and set "time until next attack" which you count down each frame

[hoary ice]

FCK!

it worked

im so dumb

thanks @naive pawn

your name is such a stranger

thanks again

[hoary ice]

this made so much sense to me lol

[lavish dove]

YESSSS

That was the problem.
Appropriately public static Vector3 MoveTowards(Vector3 current, Vector3 target, float maxDistanceDelta); If the maxDistanceDelta is negative the object will move in the opposite direction.
My code had timeOfArrival - Time.time; so on the first frame it's 5f - 0, but the next time round it'll be 5-f - 10.81f whatever so it's a negative.

Thank you for helping me rubber duck this one guys 😅

Always remember to understand fully the code you've copied off the internet 😅

[topaz fractal]

how can i create a drag variable for my charactercontroller?

[swift crag]

drag is just a reduction in velocity over time

very simple drag could just be

velocity = Vector3.MoveTowards(velocity, Vector3.zero, Time.deltaTime);

this slows you down by 1 m/s per second

[ruby python]

Am I missing something with Scriptable Objects or can you not assign GameObjects or Transforms that already exist in the scene to them?

[swift crag]

Assets can't reference scene objects

It's the exact same situation that you have with a prefab

(because prefabs are assets, too!)

[ruby python]

Ah bugger.

Okay, thanks.

[chrome shadow]

why isn't the value f updating?

[swift crag]

Several things here.

[chrome shadow]

oh wait

i realised

[swift crag]

f is a local vareiable of Update. It does not exist outside of Update, and it does not persist.

You're modifying f after you use it, so the change you made on the last line of Update isn't visible anywhere

Notice how your IDE is highlighting the variable here

[chrome shadow]

ahhh

[swift crag]

It's warning you that the assignment was pointless.

thirdly: Mathf.Lerp(0, 100, 10f) does not use the f variable at all

(the "f" in 10f just means that it's a float, rather than an integer)

Mathf.Lerp(0, 100, 10) will just return 100. Lerp gives you a value that's a percentage of the way between the first and second arguments.

The third argument is clamped into the [0..1] range, so you don't get 1000 or something

[chrome shadow]

omg tysm i love this channel

[carmine sierra]

what in this code is causing my character to move up from a y pos of 1.96 to 3.32 on the click of any key?

[swift crag]

It's probably starting out stuck in the ground.

When you move a character controller, it will find a position that isn't stuck inside a collider.

[chrome shadow]

why does the increase speed slow down at like 99?

[carmine sierra]

your right, the collider was larger than the player

[swift crag]

so this is a very common error

[rocky canyon]

https://gamedevbeginner.com/the-right-way-to-lerp-in-unity-with-examples/

[swift crag]

Lerp gives you a value that's a percentage of the way between two values.

If the first value is approaching the second value, then moving 10% of the way moves you less and less each time.

Mathf.Lerp(0, 100, 0.1f) gives you 10

Mathf.Lerp(90, 100, 0.1f) gives you 91

[polar acorn]

Because you are moving the object some percentage of the way between f and 100. That percentage is the amount of time between frames. So you're setting it to about 2-5% if the way between current and 100

[swift crag]

If you want to linearly move between two values, you should track how much time has passed in your variable, and then use that as the third argument to Lerp.

[rocky canyon]

aka it'll never reach its target that way

[swift crag]

float progress = 0;

void Update() {
  progress += Time.deltaTime;
  Mathf.Lerp(0, 100, progress);
}

This will give you a value ranging from 0 to 100 across one second.

[chrome shadow]

ohhh

[swift crag]

note that my example does nothing with the result -- you presumably want to store it in another variable or use it

[rocky canyon]

when u pass in the value ur lerping its gonna get closer and closer and closer but never get there

[carmine sierra]

what is that unity doc website

[chrome shadow]

wow thanks a lot guys

[carmine sierra]

with all components

nvm found it

[chrome shadow]

im learning so much this is so fun

[rocky canyon]

https://docs.unity3d.com/Manual/ the manual?

[carmine sierra]

yh i found it

what is step offset for?

it doesnt help in the docs

[swift crag]

https://docs.unity3d.com/ScriptReference/CharacterController-stepOffset.html

Note: See the Manual page Character Controller component which describes stepOffset in detail.

https://docs.unity3d.com/Manual/class-CharacterController.html

The character will step up a stair only if it is closer to the ground than the indicated value. This should not be greater than the Character Controller’s height or it will generate an error.

[carmine sierra]

yeah i checked that

[rocky canyon]

stairs

[carmine sierra]

oh ok

[naive pawn]

it's how high the knee is 👍

[rocky canyon]

nu uh.. i can step up on things higher than my knee

[spiral oak]

Hey, I'm having trouble with an issue I don't understand. For any reason, whenever I remove a +1 from my code, Unity hangs with the "Waiting for user code in mscorlib.dll to finish executing" message. Any idea what could be happening?

[naive pawn]

smh autojump user over here

[rocky canyon]

😄 just messin w/ ya

[swift crag]

If i is zero, this will skip nothing

I suspect you're getting stuck in the do-while forever

[rocky canyon]

lol

[spiral oak]

so in recent Unity versions you get that message whenever your code gets stuck in a loop?

in older versions it just freezed

[swift crag]

it's a coincidence: you're just seeing whatever the editor last displayed in the GUI

it got stuck, so it can't update the GUI anymore

[spiral oak]

oooooh gotcha

thanks mate :>

[swift crag]

the editor would run really really slowly if it could only do one "thing" every time it updated the UI

so it might show you something stale as it freezes

Hey, been trying to get this raycast working for a while now, - https://gdl.space/aziyanusal.cs - the isGrounded bool never becomes true and I can't figure out why. All of the layers have been correctly assigned and the distance can be visually seen through the ground.

[swift crag]

Is transform.position flush with the ground?

or is it a bit above the ground?

In 2D physics, you can configure whether or not queries can hit colliders they start inside of

[silver flicker]

It's my player object, so it has gravity and does hit the ground

[swift crag]

that doesn't answer my question

where is transform.position? show a screenshot with the player selected

make sure you're set to "Pivot" and "Local" in the top left corner

[silver flicker]

In game view or in scene view?

Scene** got it

[swift crag]

Scene view, yeah

[silver flicker]

This is my player object

[errant pilot]

Guys i want my games quality and size to be the same for different phone aspect ratios how can i do that?

[swift crag]

press W so that I can see some handles

e.g.

[swift crag]

Okay, so that's at the center of the collider. It's not at the bottom. That's good.

Make sure that includedLayers is correct.

Also, can I see an example where the ray is visible?

[silver flicker]

The red line is the ray

        bullet.transform.rotation = Quaternion.Euler(0, 0, shootingPoint.rotation.eulerAngles.z);
    }
}
``` can someone help me on why my bullet doesn't go forward, it just falls down?

[swift crag]

You shouldn't need to set the rotation at the end there.

[cyan shoal]

it's because the bullet was faced the wrong way.

[swift crag]

You're already using the shootingPoint's position and rotation in the Instantiate call

This shouldn't make the bullet fail to move, though

Make sure that bulletForce isn't set to 0 in the inspector.

[cyan shoal]

it isn't

[silver flicker]

Ah, I got it working fen, it looks like i was confusing the tags with the layers. Thanks for helping me realise that lol

[swift crag]

is shootingPoint rotated 180 degrees on the X/Y axes, or something?

[swift crag]

ah, yeah, that'll do it

[cyan shoal]

well, I'll see, but I just need help on the bullet not shooting outwards, and just falling

nvm got it working perfectly

thank you @swift crag

[swift crag]

what was the issue?

[ruby python]

Hey all, I'm having a little bit of a brain blockage atm, and hope someone can point me in the right direction.

            if(hitInfo.collider.gameObject.CompareTag("Enemy"))
            {
                GameObject enemyHit = hitInfo.collider.gameObject;
                Enemy enemyScript = enemyHit.GetComponent<Enemy>();
                EnemyImpactController enemyImpactController = enemyHit.GetComponent<EnemyImpactController>();
                enemyScript.enemyCurrentHealth = enemyScript.enemyCurrentHealth = playerPrimaryWeapon.laserDPS;
                enemyImpactController.EnemyHealthCheck(enemyHit.transform.position);
            }

I have this code which is for a laser weapon, it works great but I need to 'slow down' the amount of damage that is sent to the enemy script (enemyCurrentHealth) on this line.

enemyScript.enemyCurrentHealth = enemyScript.enemyCurrentHealth = playerPrimaryWeapon.laserDPS;

Current laserDPS is set to 0.1f. I can't for the life of me think of how to 'slow down' the subtraction of laserDPS as at the moment it's instant 0.

This gets called in Update btw.

[swift crag]

this just sets the enemy's health to 0.1

you wrote an = sign

[ruby python]

Yep, just spotted the typo. lol.#

[swift crag]

Also, you need to factor in Time.deltaTime once you're subtracting

Otherwise you're subtracting 0.1 every physics update

so you'd be doing 0.1*50 = 5 damage per second

[ruby python]

I'm being such a spanner at the minute. lol. Could you point me in the rough direction for this please?

[swift crag]

think about the units

[lethal bolt]

Does anyone know an sulution i couldnt find one?

[swift crag]

playerPrimaryWeapon.laserDPS

this is measured in damage per second

[swift crag]

did you read the error message

notably, this part:

There is no implicit reference conversion from 'UnityEngine.GameObject[]' to 'UnityEngine.Object'.

[lethal bolt]

Oh

[swift crag]

You need to convert this into plain damage -- not damage per second

So you need to multiply this value by a duration

[lethal bolt]

But why. Is it because the prefabs has children?

because i have done the list thing before

[swift crag]

damage   seconds   damage
------ * ------- = ------
second      1        1

[swift crag]

no, C# has no clue about your prefabs at all

You gave it an array of game objects.

It can't accept an array of game objects

Ever.

[ruby python]

You're trying to reference a single GameObject prefab on instantiate, but your tiles are setup as an array

[lethal bolt]

oh

[ruby python]

Ah thank you. Sorry, brain a bit mushed. lol

[misty pecan]

RaycastHit2D[] hits = Physics2D.CircleCastAll(transform.position, targetingRange, (Vector2)transform.position, 0f, enemyMask);

Hashtable hitsTable = new Hashtable();
foreach (RaycastHit2D hit in hits)
{
hitsTable.Add(hit.transform.gameObject.GetComponent<Enemy>().progress, hit.transform);
}
target = ?;

I want the target to be the highest progress enemy's transform, ive been stuck trying to figure out how?

[swift crag]

don't use Hashtable; it's non-generic

so it just holds object

you should use Dictionary in its place

however, that's also not appropriate here

[misty pecan]

what should i do?

[swift crag]

You really just need to keep track of the enemy with the highest progress

there's no need to store an entire collection

float best = -1;
Enemy bestEnemy = null;

foreach (var hit in hits) {
  if (hit.transform.TryGetComponent(out Enemy enemy)) {
    if (enemy.progress > best) {
      best = enemy.progress;
      bestEnemy = enemy;
    }
  }
}

if (bestEnemy) {
  // do something with it
}

note a few other changes here

there's no need to do hit.transform.gameObject -- you can just use the hit transform directly to call TryGetComponent

and TryGetComponent means that this won't throw an error if you accidentally hit something that doesn't have an Enemy on it

[misty pecan]

Does var mean it can be any datatype?

[swift crag]

No, it just means that the type is inferred

var x = 1;
int x = 1;

These are equivalent

[misty pecan]

ohh

[swift crag]

var is not an "any" datatype, like object (roughly) is

the really scary one is dynamic, where the type is figured out at runtime

You can use var whenever the type can be figured out from context

[misty pecan]

Ah thanks

[swift crag]

An annoying exception is enumerating a Transform

foreach (var child in transform)

child winds up being an object

foreach (Transform child in transform)

this works correctly

it's because Transform implements IEnumerable, not IEnumerable<Transform>

All it promises is that it'll give you objects

[misty pecan]

implements IEnumerable?

[swift crag]

That's the interface that lets your class be used with foreach

(among other things)

Most of the time, you implement IEnumerable<T> where T is some specific type

[swift crag]

That'd make this first example work properly.

[misty pecan]

Oh ok thanks

[timid oriole]

https://gdl.space/oqinajojer.cs

why is my character flipping on its side help 🙂

[swift crag]

anyway, does this make sense?

[carmine sierra]

I know that velocity needs to be applied as a new vector3

but since i was using a character controller before, i wanna know how I can change what i had previously into a WASD movement system

[swift crag]

Everything should continue to work just fine

[slender nymph]

you need to transform your input to be relative to the rigidbody's rotation. you can achieve that by calling transform.TransformDirection on the rigidbody's transform and pass in your direction vector. it will return the rotated vector

[misty pecan]

Thanks sm it works perfectly

[carmine sierra]

how would that help with the movement

[slender nymph]

that would make it move in the correct direction

[timid oriole]

Can someone help me with my issue whenever you guys are done helping him

[slender nymph]

Don't Ask To Ask

there's also no queue, so just ask your question

[willow scroll]

It's strange to me how global and local pivos for your player are the same...

[willow scroll]

They have already asked it above

[timid oriole]

it was above but got lost in the messages

[timid oriole]

wym?

[carmine sierra]

so i cant just change the one line and get it working

[slender nymph]

then maybe link to it or something next time instead of implying you haven't asked it yet

[slender nymph]

i don't know wtf you are referring to by that

[carmine sierra]

the last line

I have the direction set, i just need it to translate by that in the direction the thing is facing

[slender nymph]

and i told you how to get the correct direction. so do that

[willow scroll]

The player is moved down. Your scene shows the player's global arrows. It gets reversed, but still moved down, so, for some reason, it's ordinate, the yellow (or green) arrow is not changed.

[carmine sierra]

what tutorial can i watch, i dont know enough to understand how i can get from what you told me to do to the result

[timid oriole]

hmmm so Is this a coding issue ?

or rigidbody issue

[willow scroll]

Could you give the screenshot with the local directions now?

[slender nymph]

do you really need a tutorial that tells you how to write one line of code to call a method i already explained how to use?

[willow scroll]

Do you know what local directions are?

[timid oriole]

local direction is different than world space direction

local direction is relitive to the object I think where direction is just direction in space that's static

[willow scroll]

Yeah, I want you to select Local Space in the scene window

[timid oriole]

i selected it

[willow scroll]

And now show the arrows

[carmine sierra]

i went on docs and it doesnt help me understand how transformdirection works

[willow scroll]

Transforms direction from local space to world space.

[slender nymph]

did you not bother reading what i said about how to use it?

[carmine sierra]

you said it will return the rotation

but how do i pass that into the new vector3()

each parameter is a diff axis

[slender nymph]

no i didn't, i said it returns the rotated vector

[carmine sierra]

ohh okay

[slender nymph]

not a rotation. but rather the actual vector3 you will use

[carmine sierra]

so then i would just translate that rotated vector?

[slender nymph]

wtf do you mean by "translate" it? tell me you aren't going to attempt to use transform.Translate

[willow scroll]

Now you can see the ordinate not going from the bottom to the top

[carmine sierra]

i just call moving it translate

[timid oriole]

I don't understand what ordinate is exactly?

origin?

[carmine sierra]

the rb.velocity = new vector3(x,y,z)
and transform.transformdirection is meant to go in here somewhere

[slender nymph]

words have meaning. you should use the correct words to mean the correct things otherwise you're going to run into issues where people are misunderstanding what you are actually trying to do

[willow scroll]

You may try using your browser

[carmine sierra]

idk what else to call it, moving it?

[swift crag]

notably, setting a velocity is not "translating" a rigidbody

you're setting the rigidbody's velocity

that's it

[timid oriole]

I read the defention but I don't understand it lol. It's a distance between coordinates?

[slender nymph]

at this point you are practically asking us to spoon feed you the answer. put in some effort at solving your issue with the information provided

[carmine sierra]

i dont even know where to start tbf

[swift crag]

new word located

[swift crag]

there are only two objects in existence here

• rigidbody
• a vector

[willow scroll]

Is that a problem with your browser?

[swift crag]

in common usage

in some fields, perhaps

[swift crag]

just call them the X/Y/Z axes and it'll be significantly more obvious what's being described

[willow scroll]

It tells you:

the y -coordinate

What else has y? Right! Vectors!

[timid oriole]

yeah

[willow scroll]

Currently, I prefer using cool words

[swift crag]

I would never call the green arrow the "ordinate".

It's not a single coordinate. It's a basis vector of a coordinate space.

[willow scroll]

Well, I've mentioned that it's not the same as the player's global one now

[timid oriole]

perhaps this issue stems from incorrect blender export settings?

as unity and blender planes are different

the y in unity is up where blender y is horizontal

[carmine sierra]

if the transform.transformdirection function returns the rotation why do i need to pass in parameters

[swift crag]

what?

[slender nymph]

it's like you didn't even bother reading what i said about using that method or what the docs said about it

[swift crag]

did you read anything we've told you? I genuinely don't think you have.

#💻┃code-beginner message

[carmine sierra]

the docs just say stuff that dont make sense to me

[willow scroll]

Yeah, but it seems like Rigidbody should move the character to the left, which is it's local down. So I'm not sure why it rotates it.

[swift crag]

You give it a vector. It gives you a new vector.

The vector you give it is interpreted as a local-space direction

The vector you get is a world-space direction

If you give it Vector3.forward, you'll get a world-space vector that points in the direction that is your "forward"

[timid oriole]

same

[swift crag]

so as you rotate your transform around, the resulting vector will change

[swift crag]

This isn't the rotation I'd expect for an fbx imported from Unity

You get a 90 degree rotation around the X axis

[carmine sierra]

ohhh okay

[swift crag]

It transforms a direction.

hence the name

[willow scroll]

I suppose, Rigidbody.velocity uses world space, so it should move the character down, as it does. Not sure whether it also rotates it. Perhaps, you have any animations, which may do it?

[timid oriole]

So it's a problem with the fbx settings then?

[timid oriole]

I removed it didn't make a difference

[swift crag]

you can avoid this problem entirely by parenting the model to an empty object

and then putting the rigidbody, etc. on the empty object

Now you can rotate the model however you want

[timid oriole]

Didn't fix it it still rotated

do you mean move everything all my scripts rigidbodys and colliders onto the empty object?

and have the playermesh just be a mesh

[swift crag]

The colliders could stay on the model.

But yes, you'd otherwise be moving most of your components to the new "Player" object

[carmine sierra]

I know this is inefficient code, but not sure how I can make this better

[swift crag]

I guess I'd just do moveDirection.z = 10f instead of using the constructor again

note that this means you're flying into the sky at 10m/s..

[willow scroll]

Is it rotated if you move the object using its Transform instead of Rigidbody?

Vector3 direction = new(moveDirection.x, Time.deltaTime, moveDirection.z);

transform.Translate(direction);

[carmine sierra]

? is z not forward

[swift crag]

oh

[timid oriole]

still moving scripts over atm

[swift crag]

🤦

Blender brain

[carmine sierra]

fairs

[swift crag]

thank god nothing uses +X up

[timid oriole]

what about the y Axis?

[ruby python]

y = up

up/down

[timid oriole]

I meant as he just put Time.deltaTime there

[ruby python]

Bugs the crap out of me when stuff uses Z up/down lol.

[ruby python]

Ah sorry, missed the conversation. lol.

[swift crag]

[ruby python]

lol. what?

[carmine sierra]

is locking my characters rotation until something triggers it a good idea

by un freezing it through script

cause they flop over when they stop walking

[swift crag]

I think you've answered your question (:

[ruby python]

Unless you need the character to rotate on the X and Z axes, you could lock those axes in the rigidbody?

[carmine sierra]

yeah but in terms of are there better solutions

also my character slides when i stop clicking the walk button

is that a rigidbody feature

[timid oriole]

y error?

[carmine sierra]

or a coding issue

[rich adder]

read it and it telsl you why
you cant directly set the property of a position v3

[ruby python]

Case sensitive

[swift crag]

well, if you don't set the velocity, then the rigidbody will keep moving as it was

first law of motion, etc.

there is friction, so it slows down

[carmine sierra]

so how can i make it so it doesnt slide

[slender nymph]

your line is backwards

[carmine sierra]

cause i dont need ice skating in the game

[timid oriole]

it tells me but it didn't help me lol my understanding was that playerRb.velocity.y gets current velocity and im just assigning it to an empty variable

[swift crag]

set the velocity to 0 when you stop moving

[swift crag]

#💻┃unity-talk message

[carmine sierra]

good idea

[rich adder]

read this
https://unity.huh.how/compiler-errors/cs1612

[slender nymph]

that's what their error is, sure. but that's not their issue. the issue is that the assignment is backwards.

[rich adder]

ohh yes mb just saw that

[timid oriole]

so something like this then? In the website it shows that he has to put pthen a dot for the coordinate like x or y its using right?

[slender nymph]

floats do not have a y coordinate

[timid oriole]

wait

im dumb it was a spelling error

V was not capitlized

[slender nymph]

yes that's part of the issue

[rich adder]

besides that, this one makes no sense on a float

[timid oriole]

yeah u right

However it still cannot move for some reason

[slender nymph]

are you calling the method anywhere

[timid oriole]

fixed update

[rich adder]

dont grab inputs in fixedupdate

[slender nymph]

nah, that's perfectly fine here

[rich adder]

is it? ohh cause its not a keydown

[timid oriole]

I thought physics related things should be in fixed update?

[carmine sierra]

if i can do input.getaxisraw to detect WASD, is there a corresponding method which detects the release of those axis keys?

[slender nymph]

is your rigidbody dynamic with no constraints on any of the axes it is supposed to be moving on?

[rich adder]

no u can check the float is 0 though

[timid oriole]

Yes

[carmine sierra]

genius

[rich adder]

its the only time it would actually be 0

although to be sure I would store it in a v3 and use that for comparison
since it has approximation, but prob overkill for GetAxis

[slender nymph]

do you have anything else interfering with its position such as a CharacterController or Animator that controls the transform.position in any of its states?

[carmine sierra]

you lost me there icl

[timid oriole]

No I don't only rigidbody

[carmine sierra]

you mean if the key were to be pressed down very minimially?

minimally

[rich adder]

normally is fine don't even worry. GetAxis will just give you 0 if you're not inputting
Im just saying I would store them in a v3 so I can do things like if(moveInputs != Vector2.zero) //not moving
`moveInputs = new Vector2(GetAxis("Horizontal"), GetAxis("Vertical")) etc..

[slender nymph]

then show the entire class because something in the code must be wrong

[timid oriole]

https://gdl.space/havufoyugi.cs

[slender nymph]

okay for starers, you do know that Update is not FixedUpdate, right? so you are calling this in Update not FixedUpdate like you said you were

[timid oriole]

I switched it when you told me to?

[slender nymph]

also make sure that your fields are set correctly in the inspector

[slender nymph]

at what point did i say to do that

[timid oriole]

someone told me to that it shouldn't be in fixed update

[rich adder]

nah I was mistaken

[slender nymph]

someone said don't get input in FixedUpdate and then were immediately corrected

[timid oriole]

ah

[summer stump]

#💻┃code-beginner message
If you wanna reread

GetButtonDown or Up or things that are only true a single frame have issues in FixedUpdate, but held inputs like GetAxis are fine since they will always last longer than a single frame anyways

[rich adder]

interesting. I was always under the impression the first press can be missed, but it makes sense since the function spans over frames anyway

[carmine sierra]

ignore this line

the rotation of the char is working

just the movement is locked to the z axis

i know where the issue is, just not how to fix it

[ruby python]

This is what I thought too tbh. Input in Update(), movement etc in FixedUpdate();

[slender nymph]

if you are just querying the current state of the input, that is fine to do where ever you are actually going to consume that input. if you are trying to react to changes in the input you need to do that in Update as FixedUpdate will likely not be fast enough for all changes to input

[rich adder]

ahh okay that makes a lot more sense now

[summer stump]

That is probably true, but as long as the input is registered at the time movement CAN happen, it is fine. If you are moving in fixed, then the missed updates wont actually make a difference

[slender nymph]

this is what is generally recommended because it is easier for newer people to understand. but it isn't always as cut and dry as that, the GetAxis methods can be used in either with very few issues happening

[ruby python]

Aaah fair enough. 🙂

[rich adder]

oh yeah that makes sense since its applied when the physics update runs

[carmine sierra]

any ideas? I dont know how I can fix this

[slender nymph]

can you share your !code correctly so that i can copy/paste the lines that are causing that instead of typing them out manually

what do you think this is doing

[carmine sierra]

the * vector3.forward?

[slender nymph]

no the entire thing. what do you think that is doing

[carmine sierra]

it gets the rotation of the vector and multiplies it by vector3.forward

[slender nymph]

now explain why you are doing that

[carmine sierra]

tbh i copied the quaternion bit from some tutorial

[slender nymph]

and you didn't read what i told you about transforming your input

[swift crag]

so you copied random code and mashed it together and you expect it to work

[carmine sierra]

i get what your saying, im rusty at this

[swift crag]

this is not a good mindset. you need to know why you're doing each thing

[carmine sierra]

i did its just i didnt have the background knowledge to understand it

[carmine sierra]

ig i am just having a rushed mindset cause i wanna make as much as possible in the time i have

[swift crag]

this is a waste of everyone's time

[slender nymph]

read this again because there's pretty much no "background knowledge" required. i explained what you use and what to pass into it
#💻┃code-beginner message

[carmine sierra]

tbh i dont see how since i learned the stuff that was stated to me

like i know what transformdirection does and the diff between character controllers and rigidbodys

and how to use move each one

so i dont see how its a waste of your time

[naive pawn]

this is stuff you couldve learned on your own through an article or a video or docs, structured to teach

[carmine sierra]

i mostly get this but i dont get what transforming the input really means

[slender nymph]

read the rest of the message to find out how to do it

[carmine sierra]

is there one good way to learn stuff like this

i like learning through my own projects, but if its necessary to do something else

then sure

[carmine sierra]

ive read it about 10 times, maybe my reading comprehension is bad but i dont really understand it

[slender nymph]

what did i tell you to pass into the TransformDirection method

[carmine sierra]

whats a direction vector?

[slender nymph]

look at your variables

[carmine sierra]

okay so ig your right ab the time wasting, cause if i knew the code i copied i would have understood what you said

[naive pawn]

there are several

[slender nymph]

ah so you didn't write any of this yourself?

[swift crag]

if you don't know what a direction vector is, it is extremely unlikely that you know what TransformDirection does

[carmine sierra]

no just the movedir line

[carmine sierra]

is direction the rotation
