God, how do I run Unity as a standard user? It runs it as an administrator every time, I haven't checked "Run this program as an administrator" In Unity or Unity Hub's properties.

rich adder
#

you're not the first..

swift crag
weary crystal
#

If I click "Run Unity as the standard user" it just prompts it again and again and... Yeah keeps prompting it.

rich adder
#

something to do with your Windows I think running you as "Eleveted" admin user instead of regular user with admin rights

#

saw it on unity forums somewhere, fuzzy on details rn

weary crystal
rich adder
#

Unity says there will be, I'm not certain ..
I never had this issue.

swift crag
#

Your PC should have two accounts by default: a user account and the Administrator account

#

As the user, you can still elevate to do things that require admin privileges

weary crystal
swift crag
#

well, there's the problem!

#

"Run as Administrator" means that, if you aren't currently an admin, the program will elevate to gain admin privileges

#

(probably including that UAC popup)

#

but if you are the admin already, that doesn't matter

rich adder
weary crystal
#

So if I run normally but in an Admnistrator account, it will run the Unity as an Admin, no matter what we do, right?

swift crag
swift crag
weary crystal
rich adder
#

its not a fix

#

read the thread

#

It's been many months using Unity and it always opens as administrator even though I didn't mark it to be. I have crashes even in the LTS version, which cause almost all applications on my PC to stop working, I thought it was related to RAM, but I have 32 GB and it happens even with a very small scene open in the background.

weary crystal
swift crag
#

it means to gain more privileges

#

when you run an installer, and you get that UAC prompt, it's elevating

#

(I am also not an experienced windows sysadmin, so i'm probably butchering the terms a bit)

rich adder
#

is your UAC off ? @weary crystal

weary crystal
#

Ohh, well I didn't got an UAC prompt.

swift crag
#

Because you are an admin already.

#

You don't have to do anything if you are already the admin.

#

you don't have to unlock the door if you're already home

weary crystal
rich adder
#

well that explains it..

#

probably messed with UAC

#

or turned it off

#

which causes these issues

swift crag
#

This would have absolutely nothing to do with "gaming performance", btw

weary crystal
#

It's called Tiny11, I never had issues with something else though, I installed Python and used it for a while and many other dev things I don't remember.

swift crag
#

a lot of "windows optimization" and "windows debloating" is like throwing a live hand grenade in your car's engine bay

rich adder
#

maybe it was back in Windows 7 that these "minified" version mattered

#

or XP

#

I remember i had windows xp "black gaming edition"

swift crag
#

if you have just one user, and that user is an Administrator, then unity is always going to be launched with admin permissions

#

because...how couldn't it?

weary crystal
rich adder
#

at all

#

thats like saying " I installed PHP with no issues"

weary crystal
#

I know but, isn't it one of dev things?

swift crag
weary crystal
#

They both are "dev stuff" after all.

rich adder
#

python just a language, unity is an engine

swift crag
#

Make a new user account. Install Unity Hub as that user, install Unity, and you should be good.

#

You will always get this warning if your only account is an administrator.

weary crystal
rich adder
swift crag
#

they just happen to not complain if they're run with admin privileges

#

unity is mostly complaining for your own sake

#

a game engine runs a ton of random code, including a lot of code you didn't write

weary crystal
swift crag
#

if you are married to Tiny11 and you don't want to make a new user account, then you'll just need to click through the warning

rich adder
#

I "kind of" know how to make games but I don't know where to start, what type of games I make and all that.

buoyant knot
#

then you probably need to start with something very small

rich adder
#

the usual suspects : Pong ,Breakout

#

Physics? Flappy Bird / Angry Birds

buoyant knot
#

i would look at what type of game you want to end on, pick the engine that would be best for that particular game, then start with a very basic game in that engine

rich adder
#

this^
just dont make your first game Call of Duty or something llike that lol

buoyant knot
#

like if you want to make a game that is best with Godot, start by making flappy bird in godot following a tutorial

rich adder
#

Godot ?

buoyant knot
#

godot is another engine

#

good for 2D

rich adder
#

I know what godot is just found it odd mentioning it to someone who just started unity lol

#

and godot is not easier than unity Imo

weary crystal

#

i’m saying: look at dream game, find out which engine is best, start learning that engine with basic game

weary crystal
#

Is there any modeler to make an SMG better than mine?

#

some people start with the very wrong engine, and get started down a very wrong path

#

one guy tried to make mario maker with kirby using python’s pygames. Very wrong decision

he was fucked before he started

true grit : you can make any game using any engine

Hey guys, a Z-fighting question.

I have two flattened cubes in unity, that are on the exact same table at similar position (as in picture), and since they are told not to collide, they instead start Z fighting. Which is not unexpected.
But since my game will have this scenario happening all the time (cubes overlapping each other), I need to solve how to make sure one is always infront (even if there are 4 or 5 overlapping cubes.

Is there a reasonable tutorial or way to make an hiearchy on what should be shown ontop? And avoid Z fighting.

Godot is good but has a few years before it can catchup to unity's 2D

Hey I finally found a place to ask this question!
So I'm making a game where you can look at the side to rotate your camera, well the rotating works fine, but if you go to the side/boundary you can no longer turn back which is really annoying...

I decided to post the code in here:

I attached my BlueBallCollision script to my player and I assigned the BlueBall tag to the Blueball gameobject and prefab which gets instantiated. However the problem is that the player doesn't turn blue like I want him to when he gets hit for a period of 5 seconds and afterwards he's supposed to return to normal. The slowed movement doesn't work either ever since I changed the blueballcollision script from being on the player instead of the ball. Any ideas? https://gdl.space/ubasenedom.cpp

I want to learn coding all by myself, I don't want to watch YouTube tutorials or stuff, is there anyways I can learn C# that will make me enough to make indie games, at least like Flappy Bird without YouTube tutorials?

rich adder
#

Unity is just an API

weary crystal
rich adder
#

if you can learn how to read API you can use any program with c#

rich adder
#

there is no Unity c#

#

its an API for the engine which is written in c++

#

if you have c# knowledge this comes with ease, you jus need to learn what each function does

weary crystal
#

Ohh, the thing is I learnt English so easily, I just wish C# were easy to learn too, it's a language after all.

rich adder
#

so you didn't learn English in a day right?

#

it ranges from easy stuff and then progresses into harder stuff

#

easy stuff : what are variables? what are function ? what is the correct syntax

#

etc.

#

you said you know most of this stuff from other coding you did

thick goblet
#

Navarone do you know what could be causing the error I can't figure it out

rich adder

#

Yeah you're right bro, I'll try not to get bored and start playing games while learning C#, thanks, really appreciate your help man.

thick goblet
#

Wait so if I called lets say PlayerController player = collision.gameObject.GetComponent<PlayerController>(); and the rest outside of the OnTriggerEnter then it wouldn't need to be attached to the ball script

#

its the fact that its in the ontrigger

thick goblet
#

Navarone this completely fixed everything I just want to make sure I understood correctly tho. Does this instead get the PlayerController of the object which this script is attached to while the commented line got the PlayerController of the collision gameobject which didn't exist?

#

Yeah I think that's it actually

rich adder
thick goblet
#

yeahhh

#

thank you

rich adder
# thick goblet thank you

np. but you better off just putting a field in the inspector next time whenever you need a component on the same object as script

#

I thought you were looking for PlayerController on the other object since this one was named Ball or w/e lol

Yeah that would be easier lmfao

a few days ago i had my important variables showing as textmesh pro on my games gui. it would work instantly, all the variables would be set on start and the game would immediately show the corresponding figures (eg 5% crit) on launch on the screen. however now this doesnt happen and I dont know what i've done wrong. for the record, the only one that works is "timePassed" because its also sitting in the **update **bit of the script, but I dont know what is best practise here, having all of these variables just continuously updated via the Update (method?)

image.png
wintry quarry
#

because you're printing c twice

weary crystal
#

oh nvm

summer stump
#

For things like max jump, start should be fine, right? Unless that changes

zealous oxide
summer stump
#

Current health, though, will never update in start

summer stump
zealous oxide
#

yeah so as you can see in the first pic, private void start, i set the critchance, max health and current health, and up until about yesterday when i launched the game it would instantly show those variables

#

now when i launch it doesnt for some reason

#

the only thing thats updating is timepassed because its in UPDATE

weary crystal

Um I have no idea what is this, can someone help me?

what have you done

weary crystal
#

Did it divide d by a and gave me the reminder?

weary crystal
summer stump
wintry quarry
#

% is literally called the remainder operator in C#

#

it returns the remainder of the division operation

#

that's all

swift crag
#

which is an important distinction

#

-1 mod 5 is 4; -1 rem 5 is -1

#

where's my damn modulo operator, Microsoft

summer stump
zealous oxide
#

whats wierd is the crit chance one seems to completely omiss the first 5% crit i give the player inherently, so when i get the power up, rather than going from 5% to 15% (10% inc as intended), it goes from 0% to 10%

#

this was working up until like today

wintry quarry
#

And checked that there are no errors in the console?

swift crag
#

yes, you should always reach for that when things aren't adding up

#

"is this code even running?"

best way to do this? Debug.Log( maxHealth = 50;) or?

while I am here
can I check if a specific point in space is intersecting geometry

#

like a raycast but checking a single point

zealous oxide
swift crag
#

the best I know of is a small-radius sphere overlap query

queen adder
#

works, i suppose

wintry quarry
queen adder
#

like Physics.CheckSphere(randomPoint, 0,_layerMask);?

summer stump
rich adder
#

overlap is better because it gives you specific colliders as results

zealous oxide
queen adder
rich adder
swift crag
#

it's better if you need the colliders

#

but you may not

#

I used to use Overlap queries to check if the ceiling was too low

#

but that's a clear case for a Check query

queen adder
#

just need to know if the point in space has any solid colission (doing a sort of scanner effect)

rich adder
#

I usually use checks if i need to know if a spawn is blocked by anything solid, doesn't matter which

rich adder
queen adder
#

sorry not quite sure how to do this haha

image.png
swift crag
#

if you just care if something exists there, you don't care about the colliders you hit

#

you already know what the position is (it's randomPoint)

#

Do you want a point on the surface of a collider?

#

OverlapSphere would not be appropriate. You would need a raycast.

#

(or some other cast)

queen adder
#

oh so if h.Length > 0 then something IS there

swift crag
#

Correct.

queen adder
#

and that's all we care about

#

duh

#

silly ourple

swift crag
#

or you can just use CheckSphere, which returns a bool

queen adder
#

that's even realer

swift crag
#

hang on the cat just came in and is screaming

queen adder
#

oh dear!

swift crag
#

he does this constantly

queen adder
buoyant knot
#

there’s a method to get the closest point on a collider to a given point in space

swift crag
queen adder
#

so I guess I should use OverlapSphere

buoyant knot
#

.ClosestPoint

swift crag
#

If not, then you'll need to iterate over all of the colliders and check their tags

summer stump
#

But annoying boilerplate needed

buoyant knot
#

oh, you need to know if a given point in space has any collision with anything?

#

are u in 2D or 3D?

queen adder
#

3D

buoyant knot
swift crag
#

and thus we come full circle :p

buoyant knot
#

Check a sphere centered at the point in space, and the radius is the contact length that your physics system checks

#

layer mask to only look for relevant things

queen adder
#

up to no good i think

image.png
buoyant knot
#

i’m just going back to the initial question to figure out wtf he wants to do

queen adder
#

(it worked)

buoyant knot
#

gg

#

sometimes you just need to know the right method

queen adder
buoyant knot
#

i would definitely not loop through all colliders in the world. I think that will be slow as shit because of the complexity

queen adder
languid spire
swift crag
#

well, using Physics.OverlapSphere

#

i don't think anyone was suggesting to just iterate over every collider

buoyant knot
languid spire
#

and wtf do you think that actually does?

swift crag
buoyant knot
#

🤷‍♂️

#

without being able to dig into the source code, I have no idea how unity’s physics system doesn’t normally have colliders^2 time

languid spire
#

this is just damn stupid, Unity are bound by the same rules as the rest of us, there is no magic, you want to find something you loop over all available object. end of line

buoyant knot
#

unity can keep things under the hood that we don’t know about

swift crag
buoyant knot
#

like, during physics calculation, it could realistically separate things to avoid calculations between colliders that are too far

swift crag
#

hence these settings

image.png
languid spire
buoyant knot
#

i don’t think you understand

#

without being able to see the source code, we can’t know wtf unity is up to

#

we don’t know its implementation

#

we don’t know how it is optimized

#

we don’t know how shit is stored

swift crag
#

this is a multi-level miscommunication about my remark about iterating over colliders returned by a physics query

languid spire
#

of course we can, the fact that you cannot does not mean that we who know what we are doing cannot

buoyant knot
#

you can do experiments to discern, but you need source code to really see what it is doing, or need a good enough explanation of it, which I do not see

summer stump
swift crag
#

this is a given. it would be ridiculous if it wasn't the case.

languid spire
buoyant knot
#

for example, when I tried to see what 2D effectors actually do (and how they work), I just hit a brick wall. Code is injected from closed off C++. The most I could get are a few snippets from forum posts

I can't drag this prefabs transform into my scriptable objects transform fields, anyone know why?

swift crag
#

You can only reference the asset itself (so, the top-level object in the hierarchy)

buoyant knot
#

it looks like the query is operating on something like a tree or heap, with the details unknown

#

to avoid N^2 complexity

#

so more like N log N, which is much nicer

Pretty stupid question - how do you make grounded checks for character controller or gravity.

The problem is, on the "corner" on the collider it lays on the edge of the ramp. so the raycast detect it is grounded. but it does not slide down.

Here is the code:


        private void CheckIfCharacterIsGrounded()
        {
            // Check if the character is grounded.
            IsGrounded = Physics.Raycast(transform.position, Vector3.down, out RaycastHit hit, groundCheckDistance);
        }


        private void ApplyGravity()
        {
            // Apply gravity to the character controller if it is not grounded.
            if (IsGrounded)
            {
                return;
            }

            characterController.Move(gravity * Time.deltaTime * Vector3.down);
        }

        private void SetSlopeSlideVelocity()
        {
            // Check if the character is on a slope and apply sliding velocity if necessary.
            if (Physics.Raycast(transform.position, Vector3.down, out RaycastHit hit, 5))
            {
                // Calculate the slope angle.
                float slopeAngle = Vector3.Angle(hit.normal, Vector3.up);

                if (slopeAngle >= characterController.slopeLimit)
                {
                    // The character is sliding on a slope.
                    IsSliding = true;

                    // Calculate the slide direction based on the slope normal.
                    Vector3 slideDirection = Vector3.ProjectOnPlane(transform.position - hit.point, hit.normal).normalized;

                    // Apply the slide velocity to the character controller.
                    characterController.Move(slopeSlideSpeed * Time.deltaTime * slideDirection);
                }
                else
                {
                    // The character is not sliding.
                    IsSliding = false;
                }
            }

Hmm, well here's what I'm trying to do:

ItemData will hold all information pertaining to a type of item. If the item can be equipped, there is equipment mapping data to map the different parts of the equipment to different parts of the player/character model

When I create a physical prefab with this item data, I want the data to have references to all the correct parts of the equipment, but I'm having a hard time figuring out how I do that

swift crag
#

prefab children feel like they should be roughly as "first class" as the prefab parent

buoyant knot
#

I have like 3 different ways to check for ground

dawn sparrow
swift crag
dawn sparrow
#

Yeah that makes sense, I'll try doing that

swift crag
#

You can reference that component just fine

buoyant knot
#

the main way I check ground on the player (because for player it’s really fucking important) is to cast down every frame a fixed distance

#

expensive, but for just one guy it’s fine

dawn sparrow
#

Actually that's what I had originally, but I wanted to have all item data including the mapping contained in item data itself

#

But I suppose this doesn't exactly qualify as item data, it qualifies as item prefab data, so It makes most sense to put that under the prefab

buoyant knot
#

where is mr plants?

swift crag
#

Yeah. I think it makes more sense to be on the item prefab.

dawn sparrow
#

So I'll continue on with this

image.png
swift crag
#

I guess your litmus test is "if I replace the prefab, do I have to replace every single one of these fields?"

#

if so, move the fields onto the prefab

rare dust
buoyant knot
#

another way to check for ground is OnCollisionEnter/Stay. But this information is basically always 1 frame old, so it should only really supplement other information

dawn sparrow
rare dust
swift crag
#

So for things like "Armor value", that test fails: you might have various qualities of armor with the same model

rare dust
#

so it is just that "corner" case - word joke

buoyant knot
#

my player uses OnCollisionEnter/Stay. I use this to check for specific types of ground (ie ice, jumpable ground, spikes, etc). Then the next fixed update, if I am not grounded (and should not disconnect due to a jump request etc), then cast my collider down a fixed distance

#

do NOT use a square box to check for ground. Some people do that. It will get you in trouble with edges and corners

#

raycasts also struggle with checking the whole bottom

rare dust
buoyant knot
#

i’m just saying some people do

rare dust
buoyant knot
#

do you have friction?

rare dust
#

so it gets basically stuck on the edge

calm moss
#

hey, So I have a parent and 3 children. the 3rd child is a trigger. How can I use the onTriggerEnter method with one of the child GameObject colliders?

rare dust
#

good question

buoyant knot
#

in that situation, should he be on ground, or should he be falling

swift crag
rare dust
buoyant knot
#

if he SHOULD be falling, you probably have a friction issue

swift crag
#

For example, I use this anywhere I need to sense an entity:

using UnityEngine;

public class EntitySensor : MonoBehaviour
{
    public Entity owner;

    void OnTriggerStay(Collider other)
    {
        if (other.gameObject.layer == LayerMasks.entityLayer)
            if (other.TryGetComponent(out Entity entity))
                if (entity != owner)
                    OnHit?.Invoke(entity);
    }

    public event System.Action<Entity> OnHit;
}
buoyant knot
#

i don’t use capsule colliders because I do 2D. I use box colliders with an edge radius.

#

so if you fall, I can make it look convincing

swift crag
#

LayerMasks.entityLayer is just a precomputed mask for the entity layer; it's equivalent to LayerMask.GetMask("Entity")

mr plants: first thing; make sure you set the player’s material to something with no friction

#

sure. Also remember you may need platform effectors for your world. Just something to keep in mind

#

also removing friction may make your slopes wacky, depending on if you have dynamic/kinematic RB for character controller

rare dust
#

thanks 🙂

#

yeah i just didnt thought about the friktion 🙂

#

thanks for the brain push 😄

buoyant knot
#

is your character dynamic?

#

or kinematic

rare dust
#

it is not a "rigidbody"

#

it is the character controller

buoyant knot
#

gotcha. idk if friction affects that

#

character controller is like a weird mix of dynamic and kinematic

#

for 3D, there is a common kinematic character controller package you might be interested in. If you forsee having a lot more issues in future, it might be worth swapping now

ie your collider is bigger than your ground check

i know wrong image 😄

rich adder
#

what kind of ground check do you have on this

#

also your Mesh has 0 to do with collisions / grounding

#

its based on collider

rare dust
# 
        private void CheckIfCharacterIsGrounded()
        {
            // Check if the character is grounded.
            IsGrounded = Physics.Raycast(transform.position, Vector3.down, out RaycastHit hit, groundCheckDistance);
        }
rich adder
#

there you go

#

one single line shooting down

#

according to the raycast ur mid-air

#

and its causing animator to set to not grounded

rare dust
#

but that is not the problem

rich adder
#

if you say so

rare dust
#

the problem is that i get stuck there

#

so it does not slide downwards

rich adder
#

so you're not talking about that it switches to not-grounded ?

rare dust
#

even with adding gravity


        private void ApplyGravity()
        {
            // Apply gravity to the character controller if it is not grounded.
            if (IsGrounded)
            {
                return;
            }

            characterController.Move(gravity * Time.deltaTime * Vector3.down);
        }

        private void SetSlopeSlideVelocity()
        {
            // Check if the character is on a slope and apply sliding velocity if necessary.
            if (Physics.Raycast(transform.position, Vector3.down, out RaycastHit hit, 5))
            {
                // Calculate the slope angle.
                float slopeAngle = Vector3.Angle(hit.normal, Vector3.up);

                if (slopeAngle >= characterController.slopeLimit)
                {
                    // The character is sliding on a slope.
                    IsSliding = true;

                    // Calculate the slide direction based on the slope normal.
                    Vector3 slideDirection = Vector3.ProjectOnPlane(transform.position - hit.point, hit.normal).normalized;

                    // Apply the slide velocity to the character controller.
                    characterController.Move(slopeSlideSpeed * Time.deltaTime * slideDirection);
                }
                else
                {
                    // The character is not sliding.
                    IsSliding = false;
                }
            }
rich adder
#

and thinks ur mid-air

rare dust
ashen ferry
#

I think he wants to slip of the ledge in that situation idk

rich adder
#

ur still checking for wrong spot for slope

rare dust
rich adder
#

but you're technically not on a slope

ashen ferry
#

tho idk how to do that without bunch of complexity lmfao

rich adder
#

simple, switch the raycast to be an overlap

#

then you can better determine you're on a slope when on corner

buoyant knot
#

did removing friction fix the sticking issue?

rich adder
#

private void ApplyGravity()
{
// Apply gravity to the character controller if it is not grounded.
if (IsGrounded)
{
return;
}

        characterController.Move(gravity * Time.deltaTime * Vector3.down);
    }
buoyant knot
#

alternatively platform effectors, which have a mode to remove side frictkon

rich adder

its probably trying to push you down

#

because ur not grounded

what Does this Meanb

rich adder
#

Time to find youtube

swift crag
#

The timeline shows what methods ran in what order

#

Children appear below their parents

#

So, you are spending 14.14ms per frame in SoundOrbLogic.FixedUpdate

#

these are probably individual queries

image.png
#

I presume this is because you're doing all those OverlapSphere queries

queen adder
#

yeah it seems the mass OverlapSpheres calls is

#

yeash

#

hmm

swift crag
#

This will be useful for you.

#

It lets you perform a very large number of queries in one big go

#

Even if you don't manage to get any parallelism out of it, you'll still be saving time compared to doing many individual queries

#

The ideal scenario would be to start it early in the frame, then read it later in the frame (or even in the next frame)

#

note that physics commands are forcibly completed before the physics world gets messed with

#

I couldn't get RaycastCommands to run between two frames because of that, for example

#

But I still got a significant boost

queen adder
#

this is some arcane shit

swift crag
#

you just make a really big blob of commands

#

and a big array to store results in

queen adder
#

i made some improvements actually

#

simply increasing the inital radius spread, decreasing points, reducing points as range increases and making the scan more coarse did wonders

swift crag
#

You can also make the updates less frequent

queen adder
#

did that too

swift crag
#

Reducing points as range increases will be a big help.

queen adder
#

reduced scans per frame

swift crag
#

You can also cull points you can't see

queen adder
#

all in all it looks about the same but now doesn't spike

#

oh shit good point

swift crag
#

(strictly based on view direction)

#

not even thinking about occlusion culling here

#

you COULD also bake occlusion culling, and then...not quite sure what I'd do with that information, actually

#

I think you can ask "is this thing visible?"

#

but I've done very little with occlusion culling

queen adder
#

will ponder this!

Really new to unity, trad dev playing around with game dev for fun.

Trying to get a grasp of rendering/meshes/colliding/etc

Imported a random env and trying to figure out the ground prefabs

For some reason it renders in scene but when i hit play, my player controller falls on the "Concrete" (if i move in either direction a bit i fall) however i can't actually see it when i look down, it's invisible. What am i doing wrong?

image.png
swift crag
#

is it still invisible if you disable the LOD Group component?

#

that's my first suspicion

#

Also, to sanity check: add a new cube (GameObject > 3D > Cube). Can you see the cube?

#

If you can't see the cube in the Game view, then your camera is messed up

wary sable
#

So im having a silly little problem with Behavior Designer where transitioning from one of its built in nav mesh nodes to my own the character just freezes. The node still runs, and properly updates the agent destination, but it just stis there. No errors or anything

#

Ive been looking to see if their scripts change any agent settings that could screw with the movement, but I'm kind of at a loss for this one.

rancid cypress
#

im trying to code (ish) im making a simple game any ideao why this isnt working im sure its an easy fix but alas

image.png
swift crag
#

Ah, right, that's the transition.

#

Are you setting the destination every frame? I've seen problems where you never get a path if it doesn't actually manage to finish finding a path before you ask it to change destination again

#

But that shouldn't really be a problem for such a direct path (I saw that when asking for an unreachable destination)

wintry quarry
swift crag
wintry quarry
#

(the second one)

rancid cypress
swift crag
#

But, nah, if that was false, you'd see the agent cylinder moving towards the player, leaving the model behind

#

so that isn't going to be the issue

#

maybe isStopped is becoming true?

wary sable
queen adder
swift crag
#

afterward, you'd tell the points whether or not they hit anything

queen adder
#

oh, so make a big list of the random points, run them through the command, and it outputs only the ones that hit?

wary sable
#

thats stupid

swift crag
#

it'd make sense that it stops when exiting the state

#

so that it doesn't keep moving

#

although I usually just set the destination to the current position to do that

#

close enough

sly wasp
#

Oh I didn’t see it

summer stump
# sly wasp Oh I didn’t see it

you could show the code if you still have issues, so we can give more concrete suggestions.

But in essence, after declaring the class, you don't use public or void

sly wasp
summer stump
#

It isn't implicit

#

That was just an example they showed

buoyant knot
#

yeah, the instance isn't initialized

summer stump
sly wasp

# sly wasp .

Yeah, that is incorrect. It will help. No offense.

If it doesn't explain what part is confusing. We can help more

sly wasp
#

I just looked at it

#

I saw nothing like loup and soup said

buoyant knot
#

think of it this way. The class defines a circle, and you wrote a function to get the area. You cannot get the area of the idea of a circle, because that's not actually a circle. But once you have a specific circle, you can ask to get its area

summer stump
#

There are a lot of links to follow. You need to spend time on it

But like I said, show actual code

polar acorn
buoyant knot
#

if I make a circle of radius 2 at (3,5), then I can call thatCircle.GetArea(), and it should give me 4pi.

#

but I can also have a separate circle of radius 1 at (6,9).

#

I need to have a reference to the specific circle whose area I want

#

does this make sense?

sly wasp
#

Im still a bit confused. Just in case I confused any of you, im wantting to call this from the script to here in another script. I looked at the page again but im still confused

characterstorerfunction.PNG characterstorerfunctioncharacterscript.PNG
polar acorn
buoyant knot
# 
  private float radius;

  // This is a constructor to make a new circle
  public Circle(float newRadius) {
    radius = newRadius;
  }

  // Get the area of a SPECIFIC circle
  public float GetArea() { return 3.14 * radius;}
}```
then in other code, I could do something like:
```Circle circleOne = new Circle(5f);
Circle circleTwo = new Circle(1f);
Debug.Log("Circle #1 has an area of 25pi: " + circleOne.GetArea());
Debug.Log("And circle #2 has an area of pi: " + circleTwo.GetArea());```

#

You should read my comment, fishy

summer stump
# sly wasp the character show one?

That link shows all the ways to reference a script. I promise you, it is very helpful. If you can, you want a serialized reference (drag and drop)

We can't really help without more info though

Do both scripts exist in the scene before play? Are either instantiated?

sly wasp
#

the current one

summer stump
polar acorn
#

What object do you want to call that function on

buoyant knot
wary sable
#

A class needs to be tied to an object for methods to be called on it. When you are calling a method you can't refrence the class, you must refrence an object derived from that class.

In plain c#;
you can make your class:

  //vars

  public void doLemonStuff(){
  }
}```

Create an object from that class
```public class program{
  public static void Main(string[]args){ -- ignore these few lines, they are just there to show that this is in a new class that is running code.
    public Lemon myLemon = new Lemon(); -- The class must be made into an object before its methods can be used just like this
    myLemon.doLemonStuff() -- Now I can do lemon stuff
  }
}```
modest dust
#

public Lemon lemon = ...

#

it needs a name biauch

wintry quarry
wary sable
#

this isnt exactly what it looks like in unity, but this is to give you an idea of why you cant just call Lemon.doLemonStuff()

wary sable
modest dust
wary sable
#

and that could be a solution to the problem depending on what their particular script does, but that hasnt been disclosed

modest dust
#

Either way, the best explanation would be presented in a book/course when learning C#

#

Not when trying to do something in Unity with little C# knowledge

wary sable
#

yeah, thats one thing that a lot of people stuggle to comprehend when going into this is that you need to know c#

#

at least the basics

bro thats same piece of code

double check what u got in songPath ig

radiant thunder

not exactly the same but vierually the same

then songPath doesn't contain what you think it does

is this the correct component? is there more than one copy of it in the scene?

I am trying to load a scene in additive mode but it looks like that async load never gets to the isDone state.

`AsyncOperation asyncLoad = SceneManager.LoadSceneAsync(scene, LoadSceneMode.Additive);

    // Wait until the asynchronous scene fully loads
    while (!asyncLoad.isDone)
    {
        print("loading");
        yield return new WaitForSeconds(10f);
    }

    print("loaded");`

Am I missing something with scene loading?

#

oh, wait, I'm unloading the previous scene, which probably dumps the coroutine

ashen ferry
#

I think u can just do yield return new WaitUntil(() => asyncLoad.isDone); inside coroutine

timid quartz
#

I wanted the text so I could see how long it was spending loading

swift crag
#

that would still die if the MonoBehaviour your coroutine was running on got destroyed

timid quartz
#

ya my problem is that my scene switcher was getting culled

ashen ferry
#

yea its just weird

#

to wait 10 secs

swift crag
#

you could do this in a DontDestroyOnLoad'd object so that it's never unloaded

ashen ferry
#

when scene is gonna load in one lol

timid quartz
#

to each their own. for me it was equally as helpful as something printing every 1 second.

#

I just wanted to know if it was still in the while loop or something downstream

#

yanno?

#

anyway problem solved, scene switcher moved to the meta scene that I didn't want to unload (hence the additive scene load and manual unload)

#

thanks!

ashen ferry
#

u print and start 10 seconds wait just put that print before WaitUntil I sent and its the same thing

swift crag
swift crag
#

that's where the StartCoroutine method comes from in the first place -- it's a member of MonoBehaviour (rather than being a static method or something)

ashen ferry

hes not printing it in intervals well the code does that but its not gonna print again scene will be loaded ages ago

ah, that shoul be of some use- thanks!

public static Vector3 ChangeX(Vector3 v, float x) => new(x, v.y, v.z) lol then maybe u can do transform.position = ChangeX(transform.position, 50);

swift crag

so you might do

# 
Vector3 horizMove = Vector3.ProjectOnPlane(velocity, gravityVector);

that would give you the velocity perpendicular to gravityVector

useful for something like Super Mario Galaxy

it will only display folders

you are in some random folder (probably in your project)

navigate to the root directory of your project and select that.

i want to spawn a bunch of Shruiken particles at specific points, just for temporary visuals (they fade quickly.) is the best way to do this seriously to move a an empty Gameobject with a ParticleSystem attatched to each point, burst 1 particle, and then move it again until it's spawned particles at every single point?

Yeah I'd guess you have compile errors then

GUIText is extremely old

If you do not have a very good reason to not use TextMeshPro, you should use TextMeshPro.

and what do I put

using TMPro; up top. TMP_Text for the type

You should show the object in the scene like we kept asking, or just do that 👆 and hope that's the right type. Tmpro is what you SHOULD use, but maybe you used legacy?

I have a very stupid question to ask but i just dont understand. Why is the Pos Y of a rectTransform in my inspect different to the position when I run the game? I have tried localPosition and just Position but still doesnt come out right.

solar tide
#

I created a scriptable Object that has a sprite image container.
And when I put the image in and wanted to display it on screen as a tooltip I just realized.
There is no way to link UI image or a UI rawimage to a tooltip object that recieves only sprites. UI Image is considered an image and rawimage is a rawimage so if I change the code in my Tooltip object to make it recieve rawimages or image, then I can't seem to modify my own 2D sprites into images.

{

    [SerializeField] private float _moveSpeed;
    private bool canJump;


    // Start is called before the first frame update
    void Start()

        _rb = GetComponent<Rigidbody>();
    }

    // Update is called once per frame

Why does my character only move after I jump? I want it to move in a constant speed without user input.

#

I got a physics material with 0 friction on both the ground and on player.

ivory bobcat
#

With your current code, no locomotion is started till jump is pressed at least once.

final kestrel
#

Ohh

#

my bad my bad. I forgot move forward inside canJump condition

#

thanks.

#

Add force continously adds force right? Is there any way to set it so that I start and move along with the same speed?

keen dew
#

Add an impulse force once in Start

final kestrel
#

It would be too fast though no?

#

I use impulse on jump

keen dew
#

It would be as fast as the force you apply to it

final kestrel
#

It moves too fast even though I set my moveSpeed to .1

#

I am happy with the movespeed I just want it to stay consistent

keen dew
#

well you obviously have to remove the MoveForward call from FixedUpdate too

final kestrel
#

Oh? Why? I thought physics based stuff went into fixed update

keen dew
#

that's the part that keeps adding more speed to it

#

If you add force once in Start then it keeps moving at that speed if you have friction and drag at 0

final kestrel
#

Ahhh

keen dew
#

The other option is to keep what you have and set drag instead

#

And the third option is to set the forward velocity manually

final kestrel
#

you mean directly setting rigidbody velocity?

keen dew
#

yes

final kestrel
#

All right I will give it a try. Thanks!

ivory bobcat
final kestrel

Just a preference question. When equipping items, do you pass in the player's reference into its equipping function, or do you assign the reference of the player immediately when picking up the item?

queen adder
#

Can I add a component via string? Like I want to add a Stunned : Monobehaviour component to a class via "Stunned" string

timber tide
#

Kinda odd how a lot of my stuff has no ownership binding and I only pass in the references

queen adder
#

I have a list of component type names and i wanna add them in a GO

burnt vapor
queen adder
#

how blushie

burnt vapor
#

With reflection you get the component

queen adder
#

oh yea refleksi thingi

burnt vapor
#

But reflection is bad, and especially in Unity

#

You should see about code generation to prevent it, or just make a dictionary

queen adder
#

I dont mind reflection, it's just a save system thingy

timber tide
#

Yeah do a dict

burnt vapor
#

A dictionary would only work if you know the types at compile time though

#

That's why you're best off with code generation if you know how to do that

timber tide
#

You trying to save status inflictions to persist on loading?

#

could just do IDs on them effects and apply them when you restart

burnt vapor
#

Just deserialize your data and have a handler set every component manually.

queen adder
#

AYE, THANKS, IMMA GONNA DO DICTIONARY :>

#

.ToLower()

#

How can dictionary work though? I can do a switch(string) and add the component per case, but a dictionary? How?

#

what are the kvp to use?

#

Dict<string, Monobehaviour>?

burnt vapor
#

Actually, that's not true. You want to add the component and add the data through some sort of method I assume? Then I would suggest an interface

#

It really depends on the functionality

ashen ferry
#

u can assume different components needs different data to save/load how does interface solve that? Just curious cause im using switch since I couldnt figure that out without making generic poco and interpreting that per component

Here is a simple code block that gives weird results... I have a 2d-grid of cells, that want to know how many neighbours they have and who they are. I thought the quickest way to test that is to disable their own collider, OverlapBoxAll at the cells position and then reenable the collider. But for some reason some cells have really overblown results (25 neighbors) event though 9 should be the possible maximum. I really have no idea why, can anybody help?

for(int i = 0; i < _Cells.Length; i++)
  {
    _Cells[i].EnableBoxCollider(false);
    Collider2D[] colliders = Physics2D.OverlapBoxAll(_CellTransforms[i].position, Vector2.one * 1.5f, 0f);
    _Cells[i].SetNeighbours(colliders);
    _Cells[i].EnableBoxCollider(true);
  }

You can format your multiline code block with C# highlighting! Just add cs to the start of it. Highlighting example below!

class Fluffs : FluffyCat
{
    public void PetCat ()
    {
        Debug.Log ("Petting Cat.")
    }
}
sand condor
#

(Unity2020.3.34f1)

ashen ferry
#

the obvious one is ur overlap box might be too big also how can there be 9 neighbours max or result 25 your iteration cell is counted in as well prolly

slender nymph
#

also if an object has more than one collider it is possible for each of those colliders to be in the array

sand condor
#

Each cell has only one collider, and no two cells are in one spot. The box is also not too big, as only 3 instances have ridiculous high neighbor numbers. Some cells get it right, some miss neighbors or get wrong neighbors.

slender nymph
#

well you are using a different array to get the position for your boxcast. is there a particular reason for that instead of just using the _Cells array?

sand condor
#

The result is the same if I do _Cells[i].transform.position, I just though calling .transform performs a GetComponent<> each time so I cached them at the start.

#

Dumb question: OverlapBoxAll is in the xy-plane, right? Because all my cells are in xy with z = 0.

slender nymph
#

yes, 2D physics is only on the X and Y axes

#

also you are unlikely to see much performance benefit from caching the transforms. it's not really going to make much of a difference. but if you choose to keep using separate arrays you also need to be sure that your arrays are absolutely the same order or else you'll see issues where some cells have the wrong neighbors

sand condor
#

Ok thanks I'll keep that in mind, but as I said it doesn't make a difference which array I get the position from.

slender nymph
#

okay and what debugging steps have you taken to ensure only the correct objects are being detected by the overlapbox?

idle orbit
#

A quick question, I have a script from the asset store that I would like to verify regarding collisions, right now I'm getting the intended results for moving left and right with it but jumping doesn't seem to properly detect grounding (and resultingly ends with a stuck pose). So I was wondering as to what I should look for to figure out what is happening.

sand condor
#

I have checked if there are overlaps in the cells (like two cells in one position) - this is not the case. I also wrote this to check which cells are causeing problems

if(colliders.Length >= 10)
  {
    Debug.LogWarning("Too many neighbours");
    for(int j = 0; j < colliders.Length; j++)
    {
      Debug.Log(colliders[j].gameObject.name + ": " + colliders[j].transform.position);
    }
  }

But I am have really no idea what to debug because to me it seems as if BoxOverlapAll does not produce the results it should. :/

#

I mean I could rewrite it to manually check all 8 neighbors with OverlapPoint but that seems to be the dumbest solution 😄

slender nymph
#

have you drawn the boxes for the overlap box to ensure they are positioned where you expect them to be?

sand condor
#

And I dont know if that matters: All objects are instantiated, positioned, checking for neighbors etc in the same frame.

#

Might this cause problems?

slender nymph
#

it depends entirely on the order of operations

sand condor
#

Ok then this should not be a problem

sand condor
slender nymph
#

also what is the actual use case for this? because it seems like you could probably just have a 2d array where each cell can just access said array to look up its neighbors on the fly

ashen ferry
#

how do u draw a box is it 4 Debug.DrawLine or smthn

#

actually i shoulda just googled

#

first time I see Gizmos class lol

slender nymph
#

i personally just use vertx's debugging package so i don't have to do any of it manually and so that it is built right into the query

wintry quarry
#

Unity also has physics query visualizations built in to the physics debugger now

slender nymph
#

that's 3d only though

wintry quarry
#

Ah yes.

sand condor
slender nymph
#

yeah just use a 2d array then. no need for physics queries if this is just for game of life. don't even need colliders at all tbh

sand condor
# 
_Cells[i].SetDebugRect((Vector2)_Cells[i].transform.position - Vector2.one, Vector2.one * 2f);

private void OnDrawGizmosSelected()
    {
        Gizmos.color = Color.red;

        Vector3 bottomLeft = _debugRect.min;
        Vector3 bottomRight = _debugRect.min + Vector2.right * _debugRect.width;
        Vector3 TopLeft = _debugRect.max - Vector2.right * _debugRect.width;
        Vector3 TopRight = _debugRect.max;

        Gizmos.DrawLine(bottomLeft, bottomRight);
        Gizmos.DrawLine(bottomRight, TopRight);
        Gizmos.DrawLine(TopRight, TopLeft);
        Gizmos.DrawLine(TopLeft, bottomLeft);
    }

#

Well I kind of do because I don't want to fill a 2d-array with all slots

#

Each level has a unique shape made of grid - and some overlap, have holes in them etc.
