[misty ibex]

but not a good one

i think chatgpt just made some hallways instead of rooms

i mean that's fair

[pearl otter]

Haha

[misty ibex]

my problem here seems to be hyper niche

[pearl otter]

@misty ibex I really have no idea what could be causing the issue, everything does seem correct. I wish you the best of luck with getting it working though!

[tulip walrus]

Would modding questions go in this chat?

[somber nacelle]

modding discussions should be directed to the community for the game you are modding, they are not allowed here

[latent latch]

Well, unless you're asking how to make your own game moddable, but that seems like some research of your own.

[tulip walrus]

Yes, it's this.

I'm looking to pair human advice with what I read online in forums and other locations . A well-rounded idea of what to do/not to do/etc.

[somber nacelle]

well then that's not really a modding question. but also https://dontasktoask.com

[misty ibex]

fair enough, i think you for your attempt tho

[strange scarab]

Is there a way to check if a dictionary contains no key, value pairs I.e if they have all been removed

[somber nacelle]

its Count property will be 0 if it contains no objects

[strange scarab]

that's what I was looking for thankss

[modern creek]

I'm .. stumped.. What else could control which scene starts from editor play mode? I wrote some code a long time ago to force it to a loading scene, but .. commented that bit out and I'm still starting from the loading scene (instead of the current scene in the editor)

[misty ibex]

do you have a game manager script in your scenes?

[modern creek]

In my loading scene, yes, but in this new scene it's .. empty-ish.

I do have some "load first utils" in a script but nothing that should be ... doing anything that would instantiate anything?

Nothing is in the "Test Spine Character Rigs" scene and yet.. somehow my app gets forced back to the Loading scene

nothing in the codebase with InitializeOnLoad, nothing even that controls scenes that exists outside of my own scene manager which is instantiated after the game loads the loading scene....

[cosmic rain]

Perhaps that code affects the whole editor session if it run once?

[misty ibex]

yeah that could be it

[modern creek]

oh, good thought

[misty ibex]

maybe the settings are somehow still being loaded

[modern creek]

can i force the editor dll to be recompiled?

[misty ibex]

trying rebooting

[modern creek]

(aside from restarting unity)

oh, wait, no - that's not it.. see that line that's commented out that warns? I see that in the logging as expected

"forcing scene to 0"

Oh, wait. Does DDOL persist between plays?

I see the DDOL "scene" appear when I press play

[cosmic rain]

No. That's normal.

Usually. Depends.

[cosmic rain]

This would imply that your code is still running.

[modern creek]

wtf.. The funny thing is most of the google results are how to avoid this behaviour and start from a fixed scene 😛

[cosmic rain]

Your commenting out probably didn't save or get compiled.

[cosmic rain]

Make sure the editor refreshed after your changes.

[modern creek]

negative ghost rider, code's still compiling

note "player manager awakened" - there's no player manager in that scene (or anything, actually)

[cosmic rain]

..? So it didn't print?

[modern creek]

"dlich likes candy" followed by commented out lines of scene redirection

[cosmic rain]

Then it could be what I mentioned before.

Try restarting your editor.

[modern creek]

brb phone

[cosmic rain]

Where is the rest of the stuff getting printed from?

[modern creek]

those are a bunch of game objects that exist in LoadingScene

I'll restart the editor but.. still don't quite understand what would be causing it since that code is clearly compiled/updated (and the part that's sending the scene to [0] is commented out)

[cosmic rain]

You're messing with the editor runtime. Which I'm not sure resets between domain reloads.

[modern creek]

Weird, now it works. Interestingly, I see the "dlich likes candy" as soon as I start the editor (before I hit play once)

And yeah.. I suppose the editor compilation of the editor code only happens at some sort of .. editor domain reload? while the play mode compilation occurs on demand

[cosmic rain]

It's not related to code compilation lol

It's the runtime that is not being reset. Which is totally normal for programs.

[modern creek]

well I mean that bit of code there in the InitializeOnLoad doesn't .. get updated if I recompile/play. Isn't that part of the domain reload?

[cosmic rain]

It does

What it did to the editor doesn't

[modern creek]

Any way I can.. have it do so? re-instantiate the static LoadFirstUtils?

[cosmic rain]

Don't mess with editor scene manager in the first place 🤷‍♂️

[thick socket]

I know how to use "normals" to make a projectile bounce off walls

how could I "project" that path with a laser?

(like an ingame laser...not necessarily a raycast laser)

[pearl otter]

@thick socket You could use the LineRenderer component although I don't think they can be bounced off walls

[thick socket]

ooh perfect thanks

[thick socket]

1): draw lineRenderer to wall
2): raycast to wall to determine the bounce angle
3): draw another lineRenderer from the wall position with the bounce angle
4): repeat

not sure how "pretty" line renderers will be

but worth looking into

[pearl otter]

How is Unity.Mathematics.Random meant to be used? All examples I can find online just hardcode a number when initializing it, and some dont even bother, others suggest to use DateTime.Now.Millisecond or .Ticks, but the constructor only takes a uint, and .Ticks is a long (while Millisecond is an int), and converting or casting Ticks restricts the long to int.MaxValue (which makes sense) - in those cases random will always be the same seed anyway, though with this code im always getting min (in this case, 5), even with a different seed, is there another way its meant to be used or am I missing something in the logic?

public static int GetRandom()
        {
            var rng = new Unity.Mathematics.Random(System.Convert.ToUInt32(System.DateTime.Now.Millisecond + 1));
            var rnd = rng.NextInt(5, 10);

Debug.Log((System.Convert.ToUInt32(System.DateTime.Now.Millisecond)) + " | " + rnd);

            return rnd;
        }

According to the docs, .NextInt is exclusive, so id expect a value between 5 and 9, but I always get 5 (or whatever I set as min), why might that be?

[dusk apex]

I'm assuming you're reseeding it every call to the function. Try seeding once only?

What did the log print?

Millisecond plus one btw for the printing

[fervent furnace]

i use unityengine.random.range to seed it

[muted valley]

Can python be used in unity

[dusk apex]

Unity uses C# officially. I'm not aware of any other language supported.

[fervent furnace]

i remember they created a new extension so that you can use python, but i dont know the details, google it

[muted valley]

Ok i will thank you

[soft shard]

Seeding it once did seem to randomize it more often than not (still returns 5 quite often but that might be only having 5 numbers to choose from), though if the suggested usage with Random is to seed with millisecond/tick, wouldnt you want to update the seed every time you use it, as new miliseconds/ticks would have passed since the last use? - for the prints, I do get the current milisecond between 1 and 999 (as online suggested the constructor errors with a millisecond of 0)

[fervent furnace]

not sure if you can use python in game script

[muted valley]

I have a whole game in python 2d text based i want to translate to unity 2d mobile with ui

Any way to make scripts constant through multiple scenes?

Like i wanna declare a ton of variable when people load in

[pearl otter]

You can install Python Scripting in the Package Manager

[dusk apex]

What's the actual print result?

[muted valley]

Thank you sir

[dusk apex]

If the seed values are all the same the results will all be the same - first element.

[pearl otter]

You're welcome, but you should consider using C#, by using Python you will most likely be slowing down your game, and you won't be able to get coding support in the Code Support channels. Plus all of the tutorials online and forum posts around coding are in C#.

[muted valley]

Ok i will try

[pearl otter]

I also wouldn't be surprised if unity Deprecated their Python scripting package soon, I'm surprised they even have one.

[muted valley]

Last question srry electro

I couldnt find a answer online

[pearl otter]

What is the question?

[fervent furnace]

c# or python script?

[muted valley]

Any way to make variables constant through multiple scenes

Like i add a ton of variables in beginning

And trace them later on

[fervent furnace]

not sure what you want: constant or static variable

[muted valley]

Constant

[pearl otter]

ScriptableObjects could work. You could also make game objects set to DontDestroyOnLoad which will bring Game Objects and their scripts across scenes.

[soft shard]

first number is the milliseconds, second is Unity.Mathematics.Random and last is System.Random if I run it a few times, ill get different numbers for all of them, but usually 5 for the last 2

[muted valley]

I believe

Like i want to say
recruitableqb1 = “Johnson John” could i trace this later

[fervent furnace]

u cant modifiy constant in runtime, it is compile time defined
constant modifier

or readonly static

[dusk apex]

So consider trying to acquire a different value for seed

[muted valley]

So no?

[soft shard]

Interesting, do you just use the min and max values your wanting to randomize as the params with the seed? Like new Unity.Mathematics.Random(UnityEngine.Random.Range(min, max) or something else?

[fervent furnace]

yes, though the range of seed in mathematics.random is uint, but easy to write

[pearl otter]

As I mentioned above, you can use ScriptableObjects or DontDestroyOnLoad() on your game object to access variables across scenes.

[fervent furnace]

or just unchecked the return value of random.range to keep the bit pattern

[soft shard]

Sorry im not sure I understand - right now this is what im doing:

static System.Random r1 = new System.Random(System.DateTime.Now.Millisecond + 1);
        static Unity.Mathematics.Random r2 = new Unity.Mathematics.Random(System.Convert.ToUInt32(System.DateTime.Now.Millisecond + 1));


        public static int GetRandom()
        {
            var rnd = r2.NextInt(5, 10);
            var rnd2 = r1.Next(5, 10);

            Debug.Log((System.Convert.ToUInt32(System.DateTime.Now.Millisecond)) + " | " + rnd + " | " + rnd2);

            return rnd;
}

The seed is now only being set once, are you suggesting to use a hard coded value for the seed instead or a larger number?

[pearl otter]

@muted valley Have I answered your question?

[muted valley]

Yeah you did

Thanks

[pearl otter]

You're welcome.

[muted valley]

Time to get to work tmmrw

[dusk apex]

You're not supposed to reseed per call to random

[soft shard]

Oh sorry, I forgot to remove the var rng part, I wasnt using it in that snippet just testing - though I thought you were meant to use the latest value of tick/millisecond when you wanted to make sure the value youd get back is not always the same most of the time, when should you usually reseed Random?

[dusk apex]

Never again unless you're wanting to explicitly reset random to a default initial state with a given seed.

You'd seed once and simply call next whenever you're needing a random whatever.

[soft shard]

Ah ok, one last question, if the value is only meant to be passed once, does the value of the seed not affect the results? It makes sense why it would reset to the initial value (as to why I always got the min) im just trying to understand why using the current millisecond/tick is often suggested over just a hardcoded value or someone mentioned with using UnityEngine.Random to generate a seed, is it just preference?

[dusk apex]

A hard coded seed value will always give you the same result - which you might want for certain games. You can use anything to initially seed it. Oftentimes the current time in milliseconds or some not so predictable value.

[soft shard]

Ah I see, thanks for the info and help on this

[waxen burrow]

is there a way to pre-calculate the magnitude of a rigid body before applying a force to it?
IE if(rb.addforce's magnitude < maxMagnitude){ rd.addforce;}

[fervent furnace]

https://forum.unity.com/threads/how-to-find-the-force-being-applied-to-a-rigidbody.1068701/

[waxen burrow]

appreciate it

unfortunate but thank you

[waxen burrow]

Was able to make something that got close enough...
||May or may not have GPT'd this one||

        Vector3 currentVel = body.velocity;
        Vector3 acceleration = force / body.mass;
        Vector3 dragForce = -dragCoefficient * currentVel;

        acceleration += dragForce / body.mass;
        
        Vector3 predictedVelocity = currentVel + acceleration * Time.deltaTime;
        float estimatedMagnitude = predictedVelocity.magnitude;

        return estimatedMagnitude;
    }```
 I do not believe this will work with any other forcemodes other than force.
Also note that any forces outside of drag wont be accounted for unless added, so things like gravity will mess with the prediction
Final thing to note is that the dragCoefficient is some arbitrary constant that I made up... In testing I used 0.1 which works but Im sure a much better constant can be found without much work

[waxen burrow]

Ya know I just realized how pointless this is for my use case but it exists now I guess

[craggy totem]

hello devs, do someone know how to calculate proper position,
i have problem - particles should emit at collision point but it differs according world position of collision point, and i've made wrong position calcs
Custom_SimSpace_Transform is "ParticlesSystem's" Custom Simulation Space and it is located at center of car
here is script , thx in advance

        private void OnCollisionEnter(Collision collision)
            {
                var emitParams = new ParticleSystem.EmitParams();

+          //   IF I USE
-       /*      emitParams.position = new Vector3(0, 0, 0);     */
+          //   It will emit particles at "Custom_SimSpace_Transform" it is -> for example at (257,533,1043) in world postition . in other words it'll emits at center of car
+          //   So i made this thing bellow
               emitParams.position = Custom_SimSpace_Transform.position - collision.contacts[0].point;       <--- I assume ,Issue  is here
+          //   But it works not right as shown in video

                emitParams.applyShapeToPosition = true;
                Emit_1_obj.Emit(emitParams, 30);
            }

Hey, guys, does someone know how to write a script to alternate between two different sprites based on a key input? I'm remaking Flappy Bird and need to switch between two sprites of wings flapping for each spacebar input.

[dawn nebula]

wtf how did you do highlighting?

[dusk apex]

He's using the diff lang tag

[dawn nebula]

fancy, never seen that before

[dusk apex]

With + and - on the necessary lines.

You won't get proper c# syntax highlighting with it though.

[craggy totem]

Tranform.position calculation help

[spark flower]

i get null refrence here

[cosmic rain]

Fix it.

[dawn nebula]

Code tip. Instead of doing spawnPoints[_index] every time you want to access the element, just do
var spawnPoint = spawnPoints[_index];
and use the spawnPoint variable instead

will make things a lot easier to read

also faster

[spark flower]

like this?

[cosmic rain]

If it's intended to create a new instance there, yeah.

[dusk apex]

Show the error in the Unity console

[spark flower]

null refrence

for the resistance[i]

[dusk apex]

Show an image of the error from the unity console

[spark flower]

well making an instance fixed it

[fervent furnace]

looks like resistance is reference type

and you just create an array of reference but you didnt actually create the instance

[dusk apex]

The potential for error is quite high due to i being constrained to spawn point resistance length solely and not enemy point resistance length - not related to the specific error but should be considered.

You could also clear up some clutter by having local variable references of the elements being accessed from the arrays.

var enm = ...
var point = spawnPoints[_index];
...
for (int i = 0; i < point.resistance.Length && i < enm.resistance.Length; ++i)
{
    var enmRes = enm.resistance[i];
    var pointRes = point.resistance[i];
    point.sprite.enabled = true;
    pointRes.type = enmRes.type;//NRE here would mean that the element is null
    pointRes.modifier = enmRes.modifier;
}```

[native fable]

maybe stupid question

I have a list List<SystemBase> systems

Is it possible to go through the list to get exactly the heir (automatically bring the system to the class of the heir)?

[mellow sigil]

What do you mean by "heir"? The derived class?

[hard viper]

I am leaving all my methods and fields to my heir.

And nothing for my good-for-nothing daughter.

[dawn nebula]

I could see an alternate reality where the child/derived class was called the heir class.

It's not like programmers are strangers to giving multiple names to the same structures/concepts.

Method

Function

Map

Dictionary

[latent latch]

method and function do have different meanings

but function sounds cooler

same with vectors vs list

[fervent furnace]

i just call dictionary/hashmap/hashtable/array/unordered_map mapping
maps A to B

[dawn sundial]

Hi all, would you know how to add force (impulse) to CharacterController to Jump? Any ideas?

[pearl otter]

You would need to use a Rigidbody to add an impulse force. This is the code I use for CharacterController jumping.

velocity.y = Mathf.Sqrt(jumpHeight * 2 * -gravity);```

[grim kiln]

The docs for the character controller have an example on how to make them jump: https://docs.unity3d.com/ScriptReference/CharacterController.Move.html

[half prawn]

Is there any way to check that there isn't any particles inside sphere? Like CheckSphere(), but seems CheckSphere() doesn't work with particles.

[grim kiln]

What particle system are you using?

[prisma birch]

Is there a way to make objects permanently lockable/unselectable in the Scene View? There are certain VFX I have in my game that use large cubes and quad meshes with alpha clipping and transparency that I don't EVER want to be able to select from the scene view. To get around this, I can toggle picking on them in the Hierarchy or Layers options but Unity always seems to arbitrarily reset these options and there doesn't seem to be a good way to modifiy them via editor scripts. Am I missing something totally basic that would solve this problem?

[half prawn]

https://docs.unity3d.com/ScriptReference/ParticleSystem.html

[grim kiln]

You can use this: https://docs.unity3d.com/ScriptReference/ParticleSystem.GetParticles.html to get the particles at a given frame and then check their location relative to your sphere.

[half prawn]

Thanks, I will try it

[grim kiln]

I think it's the https://docs.unity3d.com/ScriptReference/SceneVisibilityManager.html SceneVisibilityManager's job

[hard viper]

I need a bit of physics help again. My blue circle is moving down through the red edge colliders (which are both a part of one composite/custom collider). The red colliders are supposed to have a one-way effector. When I use .Cast, the blue ball only gets a hit on the upper red edge shape, which it has been told to ignore because it is in the middle of it. How do I detect the lower shape?

assume my blue ball-like colliders could get complex, so raycasting from each lower surface individually is not a good idea

[grim kiln]

You could use the version of raycast that returns an array of results and get both

[prisma birch]

Hero! I could not find this. Going to give it a shot 🤞

[hard viper]

I’m not exactly sure which one you mean? A lot of the casting methods for 2D only produce one RaycastHit2D per collider hit (even if they return an array)

(sorry if I didn’t specify 2D earlier)

[thick bough]

In 3D you would use Physics.RaycastAll to receive a list of all hits

[grim kiln]

The red bars are a single collider?

[hard viper]

yes. both are part of a composite collider produced from a single tilemapcollider2D

tilemapcollider2D have been making things more complicated in terms of physics tbh

[grim kiln]

That's tricky

[dawn sundial]

doesn't make sense to have RB with CharController

[hard viper]

yeah. I’m thinking I might need to query the composite, and make a series of customcollider2D for bundles of shapes. But it seems like a hackey solution that contradicts the point of a composite collider

[grim kiln]

You might want to consider a two step raycast, with the second starting at the hit point of the first if the first is within some distance to the center of your blue ball.

[pearl otter]

Which is why I gave you code for CharacterController jumping

[dawn sundial]

I'm confused, I saw there RB only, maybe you edited, not sure.
Anyway, I have that code there. Not working :/ I'm trying to do the jump like 5th time. Never had an issue in 2D. I don't even know my name how angry I am (doing 3D movement first time for last 50 hours).. never had an issue with complex coding of various systems, but seems like 3D caught me unprepared 😄

[hard viper]

that might cause issues later when my colliders get more complex, as raycasts are similarly expensive to casting a polygon, but i’d need several to handle more complex geometries.

[pearl otter]

I did not edit it. Can you confirm the code is being ran? I'd recommend using a Debug.Log("jump test"); to check

[hard viper]

maybe unity just doesn’t give the tools to query this for 2D

[leaden ice]

use a layer mask or use the version of collider.Cast that takes multuple results

[hard viper]

the issue is the red lines are all part of one collider

.Cast only gives me one hit result per collider

Unless there is some setting idk about

[leaden ice]

ah yeah didn't realize that. Is it not possible to split that collider somehow?

You can also try doing another cast from the other direction

[hard viper]

i could split the collider, but I would need to potentially make 100 colliders separately to split it

example hard case

i would be ok with the top right part of the blue either ignoring or registering the widest red shape. But i need to know that I would detect the bottom red shape.

[leaden ice]

yeah i'd do a staged raycast here

but definitely hard with the complex shape

What's the use case of this?

[hard viper]

my semisolid (one way) platforms are generated by a single tilemap for a level. They all feed into one composite collider.
The blue blocks are blocks of arbitrary shape that can be made and pushed around

blue blocks are made by one tilemap => composite collider

[grim kiln]

Why do you need to raycast to get the lowest platform?

[leaden ice]

I think you might need to make them not one composite collider as the most straightforward solution

[hard viper]

I expect in that scenario that the blue block could at least lay on the lowest platform

[hard viper]

i worry this will be the case, but I will need to turn one collider into ~100 colliders. So I worry performance will be suck.

[leaden ice]

do you really need all of them at once?

How many platforms will be on screen at a time

[hard viper]

potentially many. it is a maker-style game

so nothing would stop the player from just drawing a bunch of platforms in a weird line like that

[grim kiln]

I'm not completely sure I understand the use case but you could try getting the corners of your custom shape and doing raycasts from the lowest ones, that would probably find your platforms.

[hard viper]

the normal unity way is to make each platform one gameobject.

[grim kiln]

Or even from all the corners, and getting the best platform to rest on.

[hard viper]

that might be the solution, but since this is for a custom physics engine, 20 raycasts for a complex shape every frame is like 20x more expensive for the most expensive part of my little physics simulation

i have just benchmarked Collider2D.Cast vs Raycast. Both are weirdly very close in cost

[grim kiln]

You could do a single corner per physics step, or frame, so the cost would be fixed but the accuracy would go down as your shape gets more complicated.

Single or fixed number.

[hard viper]

all these solutions just feel so expensive because the shapes can have arbitrary sizes

[grim kiln]

There's always a limit of some kind.

[hard viper]

it just feels like a really silly reason for the limitation

just that the cast only gives one hit per collider instead of per shape

[grim kiln]

You can alternatively choose to have many colliders, it's just another performance consideration.

How much of this do you have running right now?

[hard viper]

would you know how the scalign is in terms of cost? 1 composite with 100 shapes vs 100 custom colliders with 1 shape each?

[hard viper]

what do you mean?

[grim kiln]

The only really good way to measure is to test in your project. How much of this have your built?

[hard viper]

my physics engine is like 95% done. Just working out some last oddities/bugs

custom solver… however you want to say it

[grim kiln]

So pick one of the above options and profile. Measure on a target device. See what the cost is, scale various factors and find out how much works and to what scale.

It's the only way to be sure 👽

[hard viper]

makes sense

[grim kiln]

You may be surprised what you can get away with.

[hard viper]

yeah, I just want to avoid the kind of surprises of players breaking the game in terms of unintended lag

[grim kiln]

profile first and worry later

[hard viper]

btw feature request wise: it would be nice if CustomCollider2D were not a sealed class. So you could just inherit and make your own collider classes with their own parameters

it’s just a lot harder to use customcolliders when inheritance isn’t allowed

[thick socket]

protected bool explodesIntoMoreFireballs = false;

I have a class extend the class this is declared in...is there a way to have the extended class make this into a Serialized Field?

[leaden ice]

no

[thick socket]

darn, thanks 🙂

[latent latch]

why not just serialize it

[thick socket]

Dont want the extra "garbage" on more classes

[gray mural]

you probably can achieve this with custom editor if your field is [HideInInspector] public

[thick socket]

If I was redoing my AI in the future I probably would figure out a serializable way to do it

however I've only got 3 enemies left so dont wanna re-configure it all rn 😄

Hello, I want to make an animation listener for server client infrastructure. The client gets the state it is in with stateInfo.fullPathHash and updates the animID in its object to other clients, if the script animatorType == server, it updates the animator with the animID from the server, but I have problems with loop animations like walking, idle. How should I use the data I get from stateInfo.fullPathHash or are there any other methods you can suggest?

    void Update()
    {

        if (animatorType == animatorType.client)
        {
            AnimatorStateInfo stateInfo = animator.GetCurrentAnimatorStateInfo(0);
            int currentStateID = stateInfo.fullPathHash;
            animID = currentStateID;
            Debug.Log("currentanim Hash" + currentStateID);
        }

        //remove the query prevAnimID != animID I tried refreshing it continuously, but it had no effect.
        //I also tried animator.Play(animID, 0, 0f); but the problem is still the same

        if (animatorType == animatorType.Server && prevAnimID != animID)
        {
            animator.CrossFade(animID, 0.2f);
            prevAnimID = animID;
            
        }
    }

I'll check it out, thanks.

[tired forum]

This might seem like a super silly question, but it is a gap in my knowledge. I understand I can't play DirectX games on linux, but can I build a StandaloneWindows64 target on linux and use DirectX for the graphics API

[polar marten]

are you trying to replicate animation state in unity to something else, like a website?

[tired forum]

Aka -Can I build a D3D Game on Linux for Windows

[leaden ice]

don't see why not

[polar marten]

yes

[tired forum]

Using the unity headless, is there a parameter I can pass that will force only using D3D graphics API ?

[polar marten]

what is your objective?

you are at the start of a long journey if you are trying to render headlessly

[tired forum]

I am using game-ci to build our client - every time it builds it fails compiling our shaders because of GLES

[tawny moth]

I did not fully understand, but in short, I am trying to write a large-scale tcp udp server client. like mmorpg

[polar marten]

definitely study the mirror code

[polar marten]

i have bad news. game-ci doesn't really work

for everything but the simplest projects

[tired forum]

Yeah - this would not be that unfortunately

So for CI (aside from using Cloud Builder , which will explore) do you recommend just doing a script

[polar marten]

where does the CI have to occur? what is its purpose?

[tired forum]

I have a PowerShell script that I use atm that works on windows and headless

We would like it to occure in Github using Github ACtions

purpose is to just make our life easier and be able to reduce depedencies on people to do an internal build

[polar marten]

i guess, bigger picture, the goal is to save money? you will have to pay for a unity license anyway to run on github actions

[tired forum]

Oh no we will still pay for a license

[polar marten]

yeah i guess i'm saying that cloud build is what you should use

[tawny moth]

Thank you very much . I thought about looking in the mirror, but I'm a bit lazy. I think the best way is to examine the mirror.

[polar marten]

because you will not succeed in building a complex project in CI in the short term. it will take a really painfully large amount of product development

[tired forum]

We would like to keep our build systems all in th esame place if we can

As we have other tools that aren't unity

[polar marten]

well... it's impracticable*. this is coming from someone who has built a general CI for unity

i'm not saying it's impossible

[tired forum]

Thats unfortunate

[polar marten]

you will never be able to build il2cpp windows correctly on github actions, for example.

[tired forum]

Oh that is ok

we use mono

[polar marten]

anyway, you should use cloud build

[tired forum]

lol ok - point taken , I'll go take a gander

Thank you for the help!

[polar marten]

i have definitely tried to raise issues with game-ci in the past, and they were ignored

so i feel the same pain as you

[tired forum]

yeah atm, I just have a Github Self-hosted runner that execute a headless powershell script

[polar marten]

it's ultimately one guy. he doesn't have the bandwidth to test people's projects

[polar marten]

that's pretty much the worst possible setup lol

[tired forum]

ha - well it does work pretty well atm

I just hate windows and would prefer it to build on linux

[polar marten]

welll....

we built all our infrastructure on top of windows

[tired forum]

so if I can solve for the D3D problem, I am fairly comfortable with the rest , so long as their aren't other Unity issues

Ah - we are the opposite

[polar marten]

you definitely, absolutely cannot build unity on linux for anything but the most simple projects

[tired forum]

I am leaning that 🙂

couple of our shaders throw up when compiling with Volkan , which is why Iw as asking about forcing D3D

[polar marten]

you shouldn't have issues compiling to vulkan on any platform

it is very easy to specify the graphics devices though

[tired forum]

We are geting a reserved keyword issue , gl_

[polar marten]

well... that's a real error

[tired forum]

only happens with Volkan

Vulkan

[polar marten]

are you using ASE?

[tired forum]

Ha - I am not a shader guy - so I have no idea what that is 🙂

[polar marten]

amplify shader editor

i think you should use cloud build

[tired forum]

I'll have to ask - I don't thin so

[polar marten]

they're going to tell you this is an issue with your project

you don't specify the linux build target when building for windows, so you never have to build for vulkan anyway

so i think there are some basics you haven't figured out yet

[tired forum]

Fact

And that does make sense - infact in our project settings, we specify the graphics API for the windows target

I am wondering if this is a game-ci thing

[tired forum]

@polar marten Answer to your question - no we did not use ASE , just built in unity shader graph

[scarlet viper]

any way to pass a custom parameter to SceneManager.sceneLoaded ?

    void OnSceneLoaded(Scene scene, LoadSceneMode mode)
    {
      }

it looks like this

so i cant add custom params

[pearl otter]

No you can't. What parameter do you want to pass?

[scarlet viper]

ID of some sort

[pearl otter]

You could create your own function in your own script that can take in extra parameters.

[knotty sun]

why would you even think that you can change the signature of a method?

[scarlet viper]

im explaining the situation

[pearl otter]

Why do you need to pass an ID anyways?

[spring creek]

The scene reference contains an index and the name. Would that work for your id?

[knotty sun]

no, you are asking something fundamental to C#
A method has been defined with a signature, can I call it with a different signature. Of course the answer is no

[simple egret]

Ask in #✨┃vfx-and-particles as this is not a code question

[fluid lily]

Just reading over the Unity.Logging code, and I have seen a continued theme on Unities new packages. Why does Unity hate people modifying their code so much? Like the Unity.Logging.Logger has no virtual methods, poor documentation. Like I just want to be able to make a Logger with a specific decorator for the class Type that I pass it to with my Dependancy Injection framework

[pearl otter]

If you update Unity, the code you modified will be changed.

[fluid lily]

I think you miss understood. I am not trying to modify the source code, but inherit the class to make custom implementation

Thus virtual

[pearl otter]

Oh I see

That's a good point

But do you really need to create a custom logger? In most cases it will meet the needs of the user considering all it does it log messages for debugging purposes

[fluid lily]

Anyone who has used actually good logging frameworks have more needs then what they offer. I have Serilog working, but the adapter for it and Unity is rough at best, so was hopping this had more potential

[pearl otter]

What if you create your own logger? I'm sure it is possible since you can create editor windows.

[fluid lily]

What? I think you are talking about the console, vs the logging framework. Console is responsible for the display of the logs, which I am using Seq, and there are assets on the store that have better editor consoles. The logging framework is what gets/formats the logs, and then sends it to sinks(like console/file/seq/database)

[pearl otter]

Ah, well why not create your own logging framework?

[fluid lily]

I figured out how to do what I wanted. using

Log.Logger = new Logger(new LoggerConfig()
.MinimumLevel.Debug()
.OutputTemplate("{Timestamp} - {Level} - {Message}")
.WriteTo.File("..absolutPath.../LogName.log", minLevel: LogLevel.Verbose)
.WriteTo.StdOut(outputTemplate: "{Level} || {Timestamp} || {Message}"));

and my DI framework I can just hardcode the type in the logger I inject.

[fluid lily]

There are problems with Unities console as a sink. I have tried

[pearl otter]

That's good. Well good luck with what ever you're trying to do!

[hard viper]

Update: It works.... It's just ugly af

[stoic warren]

hello I have a problem in my code. it doesn't want to take "else" please help me, thank you

[vagrant blade]

You're missing brackets. This is a #💻┃code-beginner question.

[dusk apex]

It doesn't want to take the entire function tbh

[vagrant blade]

You're also misspelling your reference to your sprite renderer

[simple egret]

Hey at least their VS is configured properly

But yeah you're missing a bunch of curly brackets, and that's what's making it angry

[hidden flicker]

how do i average two vectors

[simple egret]

Like you would with two numbers

Add them, divide by two

Or you can do a fancy Vector3.Lerp(a, b, 0.5f) to get the mid-point between the two, which is the average

[simple egret]

new is not expected here, Lerp is a method

[hidden flicker]

got it ty

[simple egret]

Hm seeing your code, you seem to average two direction vectors, so you'd be better off using Slerp which will give off a normalized vector out of the box

[fluid lily]

So I am setting up my bootstrap scene loading. Currently if I have multiple scenes loaded in editor with bootstrap not the first one, the other scenes scripts will be called first. I tried to get all active scenes, and unload any but bootstrap and then reload them, but they won't unload on
[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
I can't find a way to reorder the load order of active scenes in the manager. Does anyone know how to do this?

[quaint crypt]

I bought a new pc and am trying to open up my project in the same exact editor version, but all script links are broken and prefab links as well. (game objects have missing links to their prefabs, linked game objects are broken as well). I brought the exact same code that was pushed from the other pc via git, so there is not a single change that i dont have on the new pc. what am i missing?

[gray swift]

Hello i have a quick question. I dont really understand how audio sources work. I am using them to make 3d sounds. I get how to set them up and do the range and everything and it works how I want it to. Now im having issues where in my script I am trying to play a 3d sound. I cant really get it to work and it isnt doing the distances right. ```using System.Collections;

public AudioSource flickerSoundOn;
public AudioSource flickerSoundOff;
private readonly float offDuration = 0.2f; // Fixed duration for which the light is off

IEnumerator Flicker()
{
    while (true)
    {
        // Turn the light off and apply the off material
        lightToFlicker.enabled = false;
        objectRenderer.material = offMaterial;
        flickerSoundOff.Play();
        // Wait for a fixed duration of 0.2 seconds
        yield return new WaitForSeconds(offDuration);

        // Turn the light back on and apply the on material
        lightToFlicker.enabled = true;
        objectRenderer.material = onMaterial;
        flickerSoundOn.Play();
        // Wait for a random time before turning the light off again
        float waitTime = Random.Range(minTime, maxTime);
        yield return new WaitForSeconds(waitTime);

object
I cut the code cuz it was long. But do I just make an empty object that has the audio source and refference that?

[simple egret]

What I'd do is only use one AudioSource placed correctly in the world. The script references it, as you have it now.
Then the script would also reference two AudioClip in which you'll drag-drop the sound effects, and call source.PlayOneShot(clip). This has the advantage of using one source to play a variety of sounds, without the sounds cutting each other out if you play them fast enough for them to overlap a bit

[gray swift]

Oh hm I see. So make an audio source in the object that I want to change and then that audio source gets recieved the clip from the code and plays there?

[simple egret]

Yep, in that case you don't drag-drop the clip to play in the Audio Source, but in the script

[gray swift]

I see. Thing is. On the object I want to make this flickering sound I already have an audio source constantly emitting a hum. So would I just make another audio source as a component. If so how would I access that one in my code? Sorry im really new to this need to watch a video or smth

[simple egret]

Yeah you can have another one on the same object, and you'd have to drag-drop it into your script.
Place your cursor where it says "Audio Source", and start the drag-drop from here

[gray swift]

Ok thank you so much. Im going to quickly try and if it doesnt work ill probs text again lol. but thanks

[mild orbit]

Is there a more performant way to stop all components that have [ExecuteAlways] from running than doing

foreach (var comp in go.GetComponentsInChildren<MonoBehaviour>())
    comp.enable = false;

Basically I only want to render a GO, not have any of its logic execute.

[latent latch]

Could seperate the logic from the render

[gray swift]

Wait am I allowed to send you my entire like long code or will I get in trouble. Cuz I made a change but still need a bit of help if thats okay

[latent latch]

so you only need to disable the logic GO

[simple egret]

Okay yeah thats what i was looking for. Its not that long but dont wanna disturb. gonna send it rn tyy

[mild orbit]

It is for an editor tool. I am creating previews of prefab assets. And when I Instantiate them to render a preview, the code is running. I don't own the prefabs.

[gray swift]

https://hastebin.com/share/xanevedawi.csharp okay so this is my code now. Im still kinda confused on how to get the right audio source to play

Do I just drag and drop it

where I set the audio source at the top

[simple egret]

Yes, but to be able to see it in the Inspector, you need to make it public like the two clips

[gray swift]

Oh yeah idk why i made it private that was dumb of me

[simple egret]

And then also remove the lines 25-28 which will overwrite the value you drag-dropped

[gray swift]

Wait whats the difference between readonly and private.

[simple egret]

Read-only is well, read-only. You can't put a new value into it with =
Private is not visible outside of the class

[gray swift]

Oh I see so once you set a read only it cant ever be changed. Thats interesting. Thank you so much for the help I figured out the other thing aswell just drag and dropped it

[latent latch]

Oh neat I been wanting to do that for my tool. How does that work exactly? Do you need to instantiate the GO first or can you directly render it from the asset/resources?

[lean sail]

Readonly can only be assigned inline, or in a constructor if you're using a plain c# class

[gray swift]

Wait im having an issue still

I did what you said and dragged and dropped it in but its still not playing in seperate audio sources

I want it from the second one

[simple egret]

Did you remove the lines in void Start() that fetch an AudioSource again, overwriting what's in the variable?

[gray swift]

I removed the ones you told me to i think\

rn its just this

    {
        if (lightToFlicker == null)
        {
            lightToFlicker = GetComponent<Light>();
        }-------

        audioSource = GetComponent<AudioSource>();
      

        StartCoroutine(Flicker());
    }```

[simple egret]

The one in the middle of that code still puts a new value into it

audioSource = - puts a new value into the variable

It says "Look for the first AudioSource component you can find on this object, and put its reference into the variable"

[mild orbit]

The 'right' way to do it is to create a preview scene EditorSceneManager.NewPreviewScene() which you can add a camera and lights to, and then instantiate the GO and add it to that scene. Then you render the camera to a RenderTexture.

[latent latch]

Ah, neat. I would expect to use another type of dummy prefab just for the render and point it to the actual prefab when I'd select it. Having to instantiate the actual logical scripts seem odd when you just need to render it.

[mild orbit]

Yeah it is a bit annoying. You could technically just find all the render components and copy them over to a new GameObject. But I think that would be worse for performance, and you would have to also copy over the transforms and children and stuff.

Using the preview scene is how Unity does all of the renders and previews of things internally too.

[elder obsidian]

Any one does have any idea about why this is happening? I'm just trying to spawn an prefab on client and host...

This is the class

using Unity.Netcode;
using UnityEngine;

public class TestPrefabSpawner : NetworkBehaviour
{
    [SerializeField]
    private GameObject _NetworkPrefabToSpawn;

    public override void OnNetworkSpawn()
    {
        Logger.Info($"Spawned with Network.");
    }

    private void Update()
    {
        if (!Input.GetKeyDown(KeyCode.Return))
            return;

        if (IsOwner)
        {
            if (IsServer)
                SpawnPrefabClientRpc(LocalPlayer.Transform.position, OwnerClientId);

            if (!IsServer)
                SpawnPrefabServerRpc(LocalPlayer.Transform.position, OwnerClientId);
        }

    }

    [ClientRpc]
    private void SpawnPrefabClientRpc(Vector3 position, ulong id)
    {
        var instance = Instantiate(_NetworkPrefabToSpawn, position, Quaternion.identity);

        instance.GetComponent<NetworkObject>().SpawnAsPlayerObject(id);
    }

    [ServerRpc(RequireOwnership = false)]
    private void SpawnPrefabServerRpc(Vector3 position, ulong id)
    {
        SpawnPrefabClientRpc(position, id);

    }

}

And it's a direct children of the player network object

I'm this close 🤏 to give up on 5 months of work because of this

For context, the prefab is being spawned on the host and visible on the client. But this error is triggered when the client tries to spawn the prefab from the ServerRpc

[gray swift]

Hey. I am trying to bake a nav mesh. Why is this happening this gap?

[hexed pecan]

Make sure there are no colliders in that gap. Or NavMeshObstacles etc.

[gray swift]

Oh wait I see. I used pro builder to make a gap in that wall. Apparently unity still thinks there is a wall there. Do you know how I can fix that?

[hexed pecan]

No idea about probuilder. Is there some leftover invisible object?

You baked again after removing it, right?

[elder obsidian]

try checking out the size of your navmeshAgent, sometimes it's too thick

[gray swift]

Yeah look

Thats when I select the walls

It thinks there is a wall there

[hexed pecan]

You might wanna try in #archived-networking

[elder obsidian]

oh, ty

[hexed pecan]

What object is selected/outlined here? Looks like that object actually has a gap. Hide it and show what remain?

[gray swift]

Its the wall selected

[hexed pecan]

Ok looks like it still has mesh data but no materials or something... you probably need to fix that with probuilder somehow

[gray swift]

Yeah this is weird

The edge is still there

idk how to remove that

[hexed pecan]

Maybe someone here #🛠️┃probuilder can help

[gray swift]

Ah

Didnt realize that was a thing thanks

I have a nav mesh setup with a sprite renderer set to follow my player. How do i set the direction the nav mesh faces. It is coming backwards towards me

It works when I make the material double sided and regular but I want it to be affected by lights so I put diffuse on

[hexed pecan]

How do i set the direction the nav mesh faces
Do you mean the sprite renderer instead of navmesh?

[gray swift]

Sprite renderer sorry yeah

It doesnt face the right way that the nav mesh makes it face and walk

[hexed pecan]

Should it face the camera or should it use the rotation of the player?

[gray swift]

Idk ig face towards the camera. Rn the nav mesh AI seems to be running its direction already ```
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.AI;

public class testMonster : MonoBehaviour
{
public NavMeshAgent ai;
public Transform player;
Vector3 dest;

// Update is called once per frame
void Update()
{
    dest = player.position;
    ai.destination = dest;
}

}``` this was all the code

[hexed pecan]

If you want the spriterenderer to face the camera, you can use LateUpdate, set its rotation to the camera rotation and then rotate it 180 degrees on Y

[toxic vault]

Why would this work fine

buttonGameObject.transform.Find("IconContainer/Text_Index").gameObject.GetComponent(TextMeshProUGUI).text

But this throws an error

buttonGameObject.transform.Find("IconContainer/Text_Index").gameObject.GetComponent<TextMeshProUGUI>()

And this only works in immediate window. The first code won't even compile!

[spring creek]

Show the whole line of code. Neither of those would compile as is, and neither make sense to even use as is.

You really would want to separate the calls instead of one long chain too. Find on its own line GetComponent on another

[toxic vault]

selectedPlayerIndex = Int32.Parse(buttonGameObject.transform.Find("IconContainer/Text_Index").gameObject.GetComponent(TextMeshProUGUI).text);

is how it goes. I have a Text_Index child object inside of the main gameobject where it stores an index in a TextMeshPro component

But I can't get it to compile. Although if I do this in immediate window, it works

[cosmic rain]

What compile errors does it throw?

Seems like you're using GetComponent .method incorrectly. Read the error and look at the method documentation.

[toxic vault]

This is through immediate window

And this is when I try to compile

[toxic vault]

Why would it work in immediate window then?

[cosmic rain]

No clue. I wouldn't recommend relying on the immediate mode with unity, as it's not a regular C# program. It relies on the C++ side a lot.

[toxic vault]

The reason I started debugging through immediate is because I couldn't get the .GetComponent working at all in code.

[cosmic rain]

You should check it's documentation. The generic method was correct.

You probably didn't have the component on the GameObject

[toxic vault]

Ok, will doublecheck everything. I just found it odd that code worked in immediate but not when running. Thanks

[indigo plume]

I lost my usb with a project on it 💀 is there any way to recover it or am i screwed

[vagrant blade]

How can you possibly recover something that was physically on something else?

This is the reason you should be using version control which keeps your project on the cloud

So unless you find the USB, take this as a learning moment and learn how to use version control before you start your project again

[spring creek]

Do you have the project on anything other than the usb?
Like a backup I mean?

[clever bridge]

Hi, not sure if this is the right channel but I'm trying to code a 2d character throwing a grenade at the player. I have this as the angle calculation

        Vector2 final = new Vector2(Mathf.Cos(angle * Mathf.Deg2Rad), Mathf.Sin(angle * Mathf.Deg2Rad));

        throwGrenade.GetComponent<Rigidbody2D>().AddForce(new Vector2(final.x * force, final.y * force), ForceMode2D.Impulse);

the enemy is not throwing it in the right direction and I'm not sure why

[dusky lake]

First, use SignedAngle

Otherwise you get the delta amount instead of the Real delta

Is only the direction or also the trajectory wrong?

[clever bridge]

I have no idea, it's all kinds of messed up

when player is near 0,0 it seems to work right

but if player moves anywhere else it doesn't aim right

[dusky lake]

Then try the signedAngle approach

[clever bridge]

I just want the direction right

[dusky lake]

Instead of Vector3.Angle

[clever bridge]

I did signed angle and it didnt' change anything

I did Vector2.SignedAngle

since it's 2d

[dusky lake]

Oh wait cause you take positions instead of directions for an angle calculation

You need to compare forward to the direction from one character to the other

[clever bridge]

I debug logged the player position and the grenade thrower position and they seem to log correctly

so their localScale.x do change

both of them

I didn't know that affected transform.position

I thought I could just get a raw angle from grenade thrower to player

[dusky lake]

Basically

var angle = Vector3.SignedAngle(Vector3.forward, player.transform.position - transform.position)

Huh that has nothing to do with scale

[clever bridge]

        Vector2 final = new Vector2(Mathf.Cos(angle * Mathf.Deg2Rad), Mathf.Sin(angle * Mathf.Deg2Rad));

        Debug.DrawRay(transform.position, final, Color.red);```

so I had to change Vector3.SignedAngle to Vector2 or it gave a red squiggle

and now the angle is always 0

[dusky lake]

Vector3 angle needs an axis I think

Im on my phone rn but try adding Vector3.up as a last Argument

[clever bridge]

angle is always 90 now

whatever z is it seems to constantly be that now

        Vector2 final = new Vector2(Mathf.Cos(angle * Mathf.Deg2Rad), Mathf.Sin(angle * Mathf.Deg2Rad));

        Debug.DrawRay(transform.position, final, Color.red);```

[dusky lake]

What do you mean whatever z is

[lean sail]

How come you even need the angle for this? If you want to throw it at the player then the direction is just player.transform.position - transform.position.

[clever bridge]

oh

I'll try that

it was a drag converting it from x and y to angle to x and y

[lean sail]

using the angle would only be like if you wanted to see if the enemy had "vision" of the player

[dusky lake]

Oh, was so focused on fixing that Code that I didnt even think about that 😂

[clever bridge]

yep, that did it

Thanks!

[lean sail]

i believe that final value you have calculated should give you the same direction. Maybe something needed to be normalized, but yea no point really doing it anyways

[clever bridge]

cool thanks

[lean sail]

oh actually, that final value would only work if this was aligned with the unit circle

[soft shard]

Losing a project sucks, as Osteel mentioned because its on a physical location there might not be a way to recover it unless you have a backup somewhere else, if you do decide to try version control, I find GitHub or BitBucket as nice gits, with "SourceTree" or "GitHub for Desktop" to access your git quite nice too, since its on the cloud, youd be able to access your projects anywhere with internet this way, and revert backups in case you mess up a version of your working project you want to restore later

[lean sail]

Is it common to get this _unity_self value cannot be null error and can i do something to fix it? It appears everytime I start the game while inspecting a SO instance. It doesnt happen if i start then click on an SO to inspect it. I dont have a custom inspector for it or anything. I assume its some corrupted data, because ive changed whats in this SO a few times (added/removed stuff)
Its not a major issue since i can avoid it, but just kinda annoying

[sleek chasm]

what does this error means ?

[rigid island]

empty animation event / missing methods

[polar marten]

this seems like a unity editor bug

[lean sail]

im aware it is, but i get it everytime when inspecting an SO and entering play mode

[sleek chasm]

everything seems to be working fine but i have these errors

[astral oriole]

`private bool IsVisibleInScreen(Camera c, GameObject target)
{
var planes = GeometryUtility.CalculateFrustumPlanes(c);
var point = target.transform.position;

        foreach (var plane in planes)
        {
            if (plane.GetDistanceToPoint(point) < PlayerController.instance.cameratest)
            {
                return false;
            }
        }
        return true;
    }`

Am I able to write this code as a job?

I'm having an issue because of the parameters that it needs to take in

[cosmic rain]

You might be able to if you only use blittable types.
Another point is that the overhead is probably gonna make it less performant as a job.

[astral oriole]

Yeah, I'm not sure if it'd be worth it :/

if its a point anyway why not transform into viewport space and check if out of bounds?

[scarlet viper]

is that supposed to not work?
I get:
ArgumentException: SceneManager.SetActiveScene failed; scene 'Mountains' is not loaded and therefore cannot be set active

but im waiting until scene is valid

It doesn't seem to be related to the code shared

Anyone know a way to get the .exe path including the file name of the .exe? I tried GetModuleFileName with p/invoke but it is just giving me C:\Users

[leaden ice]

Exe path of what

[wheat cargo]

Of the built game

I'm trying to restart the game from inside the game itself

[leaden ice]

Would it be https://docs.unity3d.com/ScriptReference/Application-dataPath.html
plus
https://docs.unity3d.com/ScriptReference/Application-productName.html
?

[wheat cargo]

Yeah I could use those, but I didn't know if there was something that would just give it to me in one go

[leaden ice]

Not sure that's possible

Since if you start a process from this process it'll be a child process, right?

[wheat cargo]

Yeah maybe not, but I was gonna try to launch a launcher process that doesn't get killed by the parent process which will launch the game again

Call of duty does this when it updates or fails to connect to the internet so I just wanted to see if I could do something similar

[leaden ice]

https://stackoverflow.com/questions/3991933/get-path-for-my-exe

[wheat cargo]

That was the first thing I tried, but GetEntryAssembly returns null presumably because it's not a standard c# application.

I'm just surprised GetModuleFileName is giving me C:\Users, from what I've researched it's supposed to give the .exe path including the filename of the .exe.

I'll just have to use Application.dataPath and Application.productName for now.

Oh my god, GetModuleFileName was working, but I was using a UI toolkit label to display the string and for some unkown reason it was only displaying C:\Users

I logged it to the log and it is the full path. I don't get why UI Toolkit was truncating it

Lol I think it thinks it is a new line character because my user folder is C:\Users\natha

Lmfao

[leaden ice]

Oof

[wheat cargo]

Big oof

As a fellow Nathan and C:\Users\natha owner, thanks for the heads up

How would I show a button "disabled" graphic without disabling the button?
I am trying to add speed settings for the game x1, x2, x5 and when you press 1 option, others would show as disabled/not active

[rigid island]

myButton.IsInteractable = false

[pearl otter]

I believe it is button.interactable = false

[upper pilot]

But that prevents from clicking on the button

[pearl otter]

Is that not what you want?

[upper pilot]

Nope

I want something like a radio options I guess, but with buttons.

[rigid island]

oh for a button that works too you are right

[upper pilot]

Selected item would have different graphic.

[rigid island]

wdym

[pearl otter]

If you want a radio button, just make it so when you click on the button, change the button text to an X, and then set the old active button text to empty.

[upper pilot]

you press x1, x1 button graphic becomes "active", but x2, x5 becomes "Deactivated"

I dont want to rename the button text

I want to change the graphic

[pearl otter]

Then change the Source Image

[upper pilot]

Is there a more elegant way?

Let me see if there is a radio button in Unity :c

[pearl otter]

If you're wanting to change the image depending on its state, then you will need to change the Image 😑

If you're wanting to change the color then you just need to change the button.color variable

[upper pilot]

Buttons have 4 or 5 states that let you set different image for each state.

I am looking for a built in way

I dont want to set graphic in script

[pearl otter]

The only other way is to have all of the images already on gameobjects and enable/disable the gameobjects depending on the image you want active, but you shouldn't do that.

[deft kindle]

How do i make a gravity tool where you can pickup objects by having the script enabled and then pressing left mouse button to pick the object up and when you hold a object you can move it like its infront of you and rotate if you hold shift and move your mouse also you can move it forward and backwards using scroll wheel and if you press left mouse button you you place it with gravity and if you right click you place without gravity?? (I know this is hard)

[pearl otter]

@upper pilot What you're trying to do is very simple, there's no way to do it without scripting unless if Toggles does what you need it to do.

[upper pilot]

There is

https://docs.unity3d.com/ScriptReference/UIElements.RadioButtonGroup.html

I just cant find how to enable this.

[rigid island]

yeah but you're in code general.

#💻┃code-beginner

most of the convos in here belong there anyway

[deft kindle]

Yea ik

[upper pilot]

right, its called Toggle Group for some reason, not RadioButton group 😮

[rigid island]

I think in here you're expected to have some sort of coding experience doing at least one of the things in your question

[pearl otter]

I'm really not sure then.

[deft kindle]

Yea i have ik i need to use a raycast and then idk what to use

[rigid island]

manyyy pickup scripts on the internet to get started, its all about how you you tailor it to your usecase

[deft kindle]

oh i just got told that using others scripts are bad

[rigid island]

its bad only if you are blindly copying

everyone in gamedev reuses scripts

[deft kindle]

oh yea i will read the code and understand what it does or ask my teacher

[pearl otter]

Ohh, RadioButton and RadioButtonGroup are not components, it looks like you need to use RadioButton radioButton = new() to use it. Its strange there isn't a component for it though.

[upper pilot]

I am using Toggle group and it does what I need

[pearl otter]

[pure garden]

Any idea on why this doesn't work

LayerMask layers = LayerMask.NameToLayer("Interactable") | LayerMask.NameToLayer("Object");
foreach (Transform obj in world.transform)
{
  if(obj.gameObject.layer != layers)
    obj.gameObject.SetActive(false);
}

If I only type one layer it works, but if i do more than one (2 in this case) it doesn't

[pearl otter]

It is because you're trying to compare one layer to multiple layers. Try this

LayerMask layers = LayerMask.GetMask("Interactable", "Object");
foreach (Transform obj in world.transform)
{
    if ((layers & (1 << obj.gameObject.layer)) == 0)
        obj.gameObject.SetActive(false);
}```

[pure garden]

yh doesnt work either i have alredy tried

[pearl otter]

I have edited this, try this

that actually works tysm

If anyone is curious, I got my app restarter working. Here is the code,

        {
            var processes = Process.GetProcesses();

            if (!processes.Any(p => p.Id == processId))
                break;

            Thread.Sleep(100);
        }

        ProcessStartInfo start = new ProcessStartInfo();

        start.FileName = processToStart;
        start.UseShellExecute = true;

        Process.Start(start);
    }
}

Code in Unity:

Does Unity loads the texture of any asset "mentioned" in the scene? Even if I have a prefab referenced in the scene Object, and no one instantiate it, it will still load it's textures to VRAM? How do I prevent it from loading everything in the scene?

[wheat cargo]

Use addressables

[latent latch]

Resource.Load or bundles

[indigo hound]

Anyone know how to fix this, what causes this?

[rough tartan]

here is the script that I use to make a player appear when he connects to the game, the only problem is that in certain cases the player who appears does not take the correct ID in his MyID variable which allows him to be differentiated from the other iterations of player, how can I ensure that the player that appears is indeed the ID that is intended for it, that is to say the ID that the script to detect as not assigning to an already existing clone?

the part of the script which makes the player appear (The script has the name CLIENT):

if (!ConnectedPlayer.Contains(NewID))
{
        NewIterationID = NewID;
        player = Instantiate(PlayerPrefab,new Vector3(0,1,0), Quaternion.identity);
        Debug.LogError("NEW PLAYER ARRIVED : " + NewID);
        ConnectedPlayer.Add(NewIterationID);
}

the part of the script present on the player and which is supposed to recover his ID (the script is called Ennemie):

void Start()
{
    clientComponent = GameObject.Find("Player").GetComponent<CLIENT>();
    MyID = clientComponent.NewIterationID;
    Debug.LogError("Player : " + MyID +" has been sumoned");
}

for exemple Here 2 player connected into the game with 2 different ID but the 2 iteration take the same ID

[shell scarab]

hey guys I couldn't really find information about this. I was wondering, if I have a bunch of references to a material, does that material get instantiated a bunch?

All the references should just be pointing to the material file right?

[soft shard]

Correct, itll all point to your asset file at design time, and only create a new instance at runtime if "GPU Instancing" is enabled on the material AFAIK

[shell scarab]

you mean only if I apply that material to something, right?

[soft shard]

Yeah, if a mesh or something references a material using "GPU Instancing", that mesh will have a new "material (Instance)", instead of directly pointing to the material - meaning changing the file material (for example, to a different color) will NOT affect instanced versions of it at runtime

[crude mortar]

well it's just that if you change properties on the .material at runtime, it will create a new instance

if you change properties on the .sharedMaterial, it will not create a new instance and instead change the properties on the shared material

[sterile elm]

Is there any way to stop player in Air if player click button in opposite direction? Im using RigidbodyFirstPersonController from standard assets

[lean sail]

arent the standard assets really old? i would assume these arent build to be completely modular, so you would have the most control while making your own movement controller

[sterile elm]

But it works fine

[lean sail]

🤷‍♂️ i cant even find the script online, but theres really only one answer to your question. Yes it is possible, you just have to code it

[sterile elm]

[sterile elm]

private void FixedUpdate()
{
GroundCheck();
Vector2 input = GetInput();

    if ((Mathf.Abs(input.x) > float.Epsilon || Mathf.Abs(input.y) > float.Epsilon) && (/*advancedSettings.airControl ||*/ m_IsGrounded))
    {
        Vector3 desiredMove = transform.forward * input.y + transform.right * input.x;
        desiredMove = Vector3.ProjectOnPlane(desiredMove, m_GroundContactNormal).normalized;
        FS.currentStepLenght = movementSettings.CurrentTargetSpeed / running;
        FS.PlayStepSounds();
        if (Running)
            Walking = false;
        else
            Walking = true;

        desiredMove = desiredMove * movementSettings.CurrentTargetSpeed;
        if (m_RigidBody.velocity.sqrMagnitude < (movementSettings.CurrentTargetSpeed * movementSettings.CurrentTargetSpeed))
            m_RigidBody.AddForce(desiredMove * SlopeMultiplier(), ForceMode.Impulse);
    }
    else
    {
        movementSettings.m_Running = false;
        Walking = false;
        
    }

}

i think its only needed to make this 🤔

backticks not quotes, also what do you mean "stop player in Air if player click button in opposite direction". do you want them completely frozen in air?

[sterile elm]

yes

[lean sail]

if you want the opposite direction of movement, i guess you could check the angle between desiredMove and the current velocity. then stopping it air depends on how u want the game to feel. You can make it kinematic but it wont respond to forces

[sterile elm]

test

    {
        GroundCheck();

            Walking = false;
            
        }
} ```

[lean sail]

read my message above this, theres probably more to consider like
how long do you want the player stopped for, should they eventually start moving in the direction of input?
you may need to ignore the y velocity when checking the opposite direction as well
Im honestly unsure if the velocity can be reliably used even, because with rigidbodies it may slide up/down slopes causing it to not be what you expect

it should be fine to just use the velocity (without the y component) normalized

[sterile elm]

I wanna make it work like in tf2

[lean sail]

then you'd probably want to look at guides which replicate source movement. i havent played tf2 in awhile but im pretty sure you dont just stop in midair in that game, which you initially described.

Given your response, I dont really think you've understood any of what i wrote above. I think you should ditch this old code you're using and just follow a tutorial online

What are some ways you guys limit the amount of database writes in order to limit server costs? For instance, I keep track of statistics for the player and I want to store these stats in a database, but obviously it would get pretty expensive to update the database everytime a stat increases since these will increase very often in my game.

thank you

[fleet furnace]

Thats not possible to do like that. Float cannot hold all of that data.
Why not just save the string??

PS: player prefs is not a good place to store game data as its easily modifiable by the user. ("hacked")

[simple egret]

Yeah save the entire DateTime as string, and DateTime.Parse() it back when loading.
Then you can subtract two DateTime and it'll give you a TimeSpan object, from which you can access seconds, minutes, days, etc.

[rigid island]

[tropic kiln]

Heya, I'm trying to do some procedural world generation using noise and meshes etc. I've just been trying to implement LOD into it but my triangles seem to be weirdly messing up towards the end of the iterations. My code is pretty simple but here's the problem:

private int[] calculateTriangles() {
    // Generate triangles
    int[] triangles = new int[(WorldGeneration.chunk_vertex_length - 1) * (WorldGeneration.chunk_vertex_length - 1) * 6];
    
    int count = 0;

    for (int x = 0; x < 252; x++) { // Should be [x < WorldGeneration.chunk_vertex_length - 1] - its not atm just for debugging
        for (int z = 0; z < WorldGeneration.chunk_vertex_length - 1; z++) {
            int baseIndex = z + x * WorldGeneration.chunk_vertex_length;

            // Just some debug code here
            if(x == 251) {
                if (z == 15) Debug.Log(baseIndex);
                if (z > 15) continue;
            }

            // First triangle
            triangles[count] = baseIndex;
            triangles[count + 1] = baseIndex + 1;
            triangles[count + 2] = baseIndex + WorldGeneration.chunk_vertex_length;

            // Second triangle
            triangles[count + 3] = baseIndex + 1;
            triangles[count + 4] = baseIndex + WorldGeneration.chunk_vertex_length + 1;
            triangles[count + 5] = baseIndex + WorldGeneration.chunk_vertex_length;

            count += 6; // Move to the next set of triangles
        }
    }

    return triangles;
}

Thanks very much for any help ❤️ (this has been killing me all day)

[latent latch]

I could only guess some floating point precision problems. I'd try to log a list of position (probably easier to write to text) and compare values

[spark flower]

can you write some examplery code, im getting the approach but some code doesnt show

[tropic kiln]

Shouldn't be - chunk_vertex_length is an int

[simple egret]

Sure thing

// convert
string str = DateTime.Now.ToString("s");

// convert back
DateTime dt = DateTime.Parse(str);

The "s" format specifier formats the date in a way that is standardized, so anyone around the world will be able to convert it back to a DateTime.

It produces a string like 2023-12-03T15:48:35

[spark flower]

i see

[simple egret]

Consider using a DateTimeOffset instead, so time zone information is preserved when saving/loading. In that case, use the "o" format string

[spark flower]

i see

works like a charm

thanks

[latent latch]

Oh, huh. Looks like what you have there is pretty standard otherwise.

  //Indices
  for (int x = 0; x < rows - 1; x++)
  {
      for (int z = 0; z < columns - 1; z++)
      {
          int offset = z + (x * columns);
          glm::vec3 tri1 = glm::vec3(offset, offset + columns, offset + columns + 1);

          render.indices.push_back(offset);
          render.indices.push_back(offset + columns);
          render.indices.push_back(offset + columns + 1);

          glm::vec3 tri2 = glm::vec3(offset, offset + 1, offset + columns + 1);

          render.indices.push_back(offset);
          render.indices.push_back(offset + 1);
          render.indices.push_back(offset + columns + 1);

          //std::cout << tri1.x << ", " << tri1.y << ", " << tri1.z << " ~~ " << tri2.x << ", " << tri2.y << ", " << tri2.z << std::endl;
      }
  }```
This is pretty much what I do in OpenGL

[tropic kiln]

Hmm that's really strange, it literally just gets to one point and then the triangles from there go back to (0,0) on the mesh

[hexed pecan]

This part looks ok to me, maybe the problem is with your vertex order or something

I suggest using something like Handles.Label in OnDrawGizmos or in a custom editor to draw the vertex indices on screen

And maybe triangle indices (divided by 3) in the center of each triangle

[tropic kiln]

Shouldn't be - I'm iterating the same way pretty much

for (int x = 0; x < WorldGeneration.chunk_vertex_length; x++) {
    for (int z = 0; z < WorldGeneration.chunk_vertex_length; z++) {
        float x_pos = x / (float)worldGen_script.lod;
        float z_pos = z / (float)worldGen_script.lod;

I'll give it a go debugging with gizmos tho

[hexed pecan]

I don't see you accounting for LOD anywhere but the vertex positions. Shouldn't it affect the vertex count too?

[tropic kiln]

chunk_vertex_length = (chunk_size + 1) * lod;

[latent latch]

rather, you're doing division to a float*

for a position so again with the precision problem of my previous post

[tropic kiln]

Even if there is a problem there it should only effect the position of the vertex slightly right? In that case it shouldn't make a difference for the triangles as I'm just referencing their indexes

[latent latch]

I'm just observing from the picture it feels less like an algorithm problem and more of a whoops the next value truncated into a wrong value

[tropic kiln]

That's true

[hexed pecan]

This is still my go-to step 1, visualize your data

[tropic kiln]

I'll start with that thanks

[rancid frost]

I had a 2d grid map, but it has no heights.
How can i make the map have hills just as these?

[latent latch]

Either prefab a custom mesh, or if you want to apply different vertex compositions then you need to modify them directly through their vertices

https://docs.unity3d.com/ScriptReference/Mesh.html

[rancid frost]

I see, I wanted to avoid adding extra vertices due to performanc reasons, is there really no other way?
I had considered tesseleation and height maps, but I combine meshes of similar materials together so that is a bit difficult to pull off

[latent latch]

no one says you have to add extra verts. Use what you got and move em around (well, assuming your hexagon mesh isnt composed of the absolute minimal verts)

[rancid frost]

it is, but your right, this probably the best way to go. Thanks

I am using the right one, with 4 triangles

[latent latch]

You can do so much more with a few more verts with miniscule performance changes. That and you've got tools like culling so it shouldn't be an issue when it comes to optimizing.

[rancid frost]

how many verts would you recommend per hex?

[latent latch]

If you make yourself the script to create the meshes, your alg will adjust it via values so it comes down to testing what you want later on

[rancid frost]

ok

thanks for the advice

That's usually how it goes for the most part anyway

would be odd to hard code vert values when it comes to primitives, but I guess you can argue that's exactly how'd you go about making a quad ;p

[rancid frost]

what are primitives?

[latent latch]

primitive shapes

[rancid frost]

ahh

[latent latch]

stuff that's usually easy to subdivide

[rancid frost]

lastly, is there a max vert count, I probably should go past?

[latent latch]

there is in unity, but it's per mesh and you're not likely to hit that unless you're doing chunks

(which is something else to consider)

[rancid frost]

I am using chunks right now, definetely increase performance since I can disable those that arent in view

[native folio]

why cant i add functions/methods to my custom network manager and call them from other scripts?

this is in my custom network manager

[simple egret]

Seems like CustomNetworkManager.Singleton returns a value of type NetworkManager, not CustomNetworkManager

You'd need to modify the definition of the Singleton property, or cast the value every time you need to access members on CustomNetworkManager:

((CustomNetworkManager)CustomNetworkManager.Singleton).test();

[native folio]

Ah

[simple egret]

Prefer the first (modify the definition) if possible

[native folio]

Is there anyway I can modify the definition of the Singleton property without modifying the original NetworkManager?

[simple egret]

Good question, never used that. Probably not, since it's static

Overrides are out of the question

[native folio]

What if I just made a new singleton in my Custom class and called it something like Instance instead of singleton

[spring creek]

You could make a SEPARATE static variable probably?
Call it Instance to avoid... ah

[native folio]

Yup lol

[simple egret]

Yeah possible

Instance => (CustomNetworkManager)Singleton;

Or marking the property with new? Can you do that on static stuff?

[native folio]

If I do this, do I also need to set the instance variable inside the awake function of my custom network manager?

[simple egret]

Probably not, if it already works without. This is a computed read-only property that just gets the value and casts it

[simple egret]

This works, you can completely shadow it with the following

public static new CustomNetworkManager Singleton => (CustomNetworkManager)NetworkManager.Singleton;

[native folio]

Dope

[steady moon]

Hi all, I've got an abstract RuntimeSet<T>:ScriptableObject class, and a TeamableRuntimeSet:RuntimeSet<Teamable> class, where Teamable: MonoBehaviour
When I serialize a field of RuntimeSet<MonoBehaviour> I expect RuntimeSets of classes that extend Monobehaviour to show up, and the TeamableRuntimeSet scriptable objects do show up, but I can't drag/select them into the field, I couldn't really find anything on it so I was wondering if someone here knows about this issue

[modern creek]

My understanding is that unity doesn't support serialized abstract classes out of the box and you need to do some [SerializeRerefence] shenannies and do your own editor drawing

Found this thread re Unity 2020 but I don't know the latest info, so maybe my info is outdated: https://forum.unity.com/threads/serializereference-genericserializedreferenceinspectorui.813366/

[steady moon]

oh great tysm I think that's it, going to do that now

[simple egret]

Reproduced your code architecture, it's not possible to do that in C# so Unity won't be able to do it eitther

Cannot implicitly convert type 'TeamableRuntimeSet' to 'RuntimeSet<MonoBehaviour>'

[modern creek]

his RuntimeSet<T> is abstract and inherits from SO fwiw

oh sorry, you were saying you were trying that in c#

[simple egret]

You'd have to dive into type parameter variance to achieve that, which involves using interfaces, and Unity doesn't support that either lol

[modern creek]

I'd utilize the adapter pattern if you're fixed on polymorphism of your underlying c# classes.. have your classes be their own thing (unrelated to MBs and SOs) and then have MBs and/or SOs to wrap them

I'm actually pretty far into a project that's doing the polymorphism thing and.. I keep the polymorphism away from unity

[simple egret]

Yeah it was not made for polymorphism, but more for composition and other design patterns

[steady moon]

ahhh gotcha, adapter seems pretty straightforward, ty!

[modern creek]

https://pastebin.com/jeKKxXuR that's how I'm doing it

it's a tile based game.. but in unity i .. don't want to have the inspector/editor have to figure out too much, so I just manually have an initalize method that I call programmatically and pass it whatever, and it can figure out what to init/display accordingly

then all my behaviour management is stuff like "if tile is IMoveable, move it" or "if tile is IDestroyable, destroy it" or whatever

every specific tile inherits from the abstract parent class and just gets all the default behaviour (like a constructor that sets the id, location on the grid, etc) and it just implements the "tile-type specific" behaviour.. like maybe one tile moves erratically or not at all each turn, maybe another can only be destroyed by another certain tile type, etc

[steady moon]

a lot of the stuff I have already depends on serialized stuff i.e. an enemy has an Teamable:MonoBehaviour, ITeamable component plus a couple other to manage health/pathfinding/alerts so I'm not sure i could make it work without a bunch of refactoring but that sounds interesting, probably keep it in mind for after the semester

[surreal geyser]

I'm trying to make a slippery floor on one of my tilemaps so that everything placed by the tilemap should be slippery. It doesn't work, I've already tried to work with materials that have 0 friction, it doesn't work and I've already tried to code it with the help of the internet but no matter how I code it, either everything is slippery or it doesn't slip at all. Is there an example code I can use or a component I can use?

[jagged snow]

I want to have a transform stop moving when it hits a wall or something is in front of it, should i use a raycast or boxcast in this situation? It could be like a leaping dog.

[vagrant blade]

Either works. Depends what shape you want the cast to be. They both do the same thing after that.

[rigid island]

easy, put the slippery tiles in a separate tilemap

so you only deal with their collider/physics material separate

not sure anything else is code related

Hi all. im a little confused. As far as i understand, animations triggers fire off, then get disabled until they're fired again. However, in this case that doesnt seem to happen:

• it doesnt seem to transition through any of the triggers (i hooked the dash animations to any state wih the corresponding trigger param as their sole condition)
• dash end seems to trigger 24/7 even hen not dashing

Does anyone know why?

[rigid island]

holy shit pastebin sucks ass

half the page is taken up by other people's scripts

[short osprey]

didnt wanna omit info that might be helpful lol..

[surreal geyser]

As far as I know I have 2 tile maps in the same grid. It should work or does it being in the same grid change something?

[rigid island]

its okay but you need to split it a bit more cause its hard to read at a glance

[short osprey]

coming from regular software dev to this is surprisingly difficult, im not even rlly aware whats wrong

hmm maybe

[rigid island]

I would debug the animator first

select the object that has the animator in playmode you should be able to see if trigger stays on or not

[short osprey]

ye i did

it never turns on, even tho the message right above it does log

[rigid island]

you can have many tilemaps in one grid it doesn't matter, but each tilemap has diff purpose so they ca be split to more if needed

[short osprey]

except dash end

i just saw the time tho, ill have to take time for it tmrw

its almost 2 am 💀

[surreal geyser]

lol for me too.

[surreal geyser]

I’ll tomorrow write here again about it. I think they are separate tile maps so it should work

[rigid island]

ohh ok thought you tried it

[astral oriole]

General question, is there a simple function to static batch objects that are instantiated? I have larger objects that spawn later and they aren't being batched

[oblique spoke]

https://docs.unity3d.com/ScriptReference/StaticBatchingUtility.html

[lean sail]

Is there a nice way to get (deterministic) random points on a certain NavMeshSurface? Currently im using NavMesh.CalculateTriangulation();, then get a random vertex, and then NavMesh.SamplePosition. but it appears that the triangulation itself is not deterministic when there are multiple surfaces. It seems to just cycle between a few different possible lists.
I was thinking of some options:

• generate the list once while only having 1 surface active, store that result on some script in every scene. This seems quite tedious though if i want to make changes
• make a script on some GO which acts as spawn points, manually input some bounds, then randomly choose a point and sample the position onto the navmesh. Seems better but then ill have to make the sample position maxDistance large enough to account for any bounds.
  Just looking to see if anyone has thoughts about what I should do

[surreal geyser]

They are seperated and doesnt matter what I do I cant get the slippery effect.

I tried different codes and they dont work. Im tryng to make a script that I add to my slipperyTile and Im tryng avoid to much change and adding of stuff in my player controls script. Can u help me make some code for the Slipperyeffect? (im new to unity and programming idk if I should have written this in Code beginner)

[swift falcon]

What player controller are you using?

[dull glade]

I don't need to worry about Time.delta time when I'm using physics like: rb.AddForce(Vector2.up * ampSpeed, ForceMode2D.Force); right?

[lean sail]

the AddForce equations already consider delta time if they need it

[surreal geyser]

I don’t know if player controller is the right name, I made the controls myself. I made like most probably do(with Tutorials/Internet) the controls with vector. I made that you only jump when there’s a ground under you and I added coyote jumping also(jump still possible for a short time after touching edge of platform) also I added with tutorials Jump higher function when u hold and shorter when u just tab quickly. I put also the animation and sounds in controls code. I also gave my player 0 friction bc I saw in a video it stops the player from getting stuck when u jump and run against a wall.

I don’t know if any of that stuff influences slippery tilemap I wanna add.

[swift falcon]

It depends on how your character moves already as there's many different ways.

[surreal geyser]

I copied those vector lines from tutorials I don’t fully understand it. Should I paste it in here?

[swift falcon]

You don't really want to conflate the methods

Yea

[surreal geyser]

Wait a min

private void Update()
{
dirX = Input.GetAxisRaw("Horizontal");

 if (Input.GetButtonDown("Jump"))
 {
     jumpBufferCounter = jumpBufferTime;
 }
 else
 {
     jumpBufferCounter -= Time.deltaTime;
 }

 if (coyoteTimeCounter > 0f && Input.GetButtonDown("Jump"))
 {
     jumpSoundEffect.Play();
     rb.velocity = new Vector2(rb.velocity.x, jumpForce);
     coyoteTimeCounter = 0f;
     jumpBufferCounter = 0f;
 }

 if (IsGrounded())
 {
     coyoteTimeCounter = coyoteTime;
 }
 else
 {
     coyoteTimeCounter -= Time.deltaTime;
 }
 if (Input.GetButtonUp("Jump") && rb.velocity.y > 0f)
 {
     rb.velocity = new Vector2(rb.velocity.x, rb.velocity.y * 0.5f);
     coyoteTimeCounter = 0f;
 }

 UpdateAnimationState();

this are the controls and the next method is where the animations are handled

wanna see that too or is here maybe the root of the problem?

forgot this private bool IsGrounded()
{
return Physics2D.CapsuleCast(coll.bounds.center, coll.bounds.size, CapsuleDirection2D.Vertical, 0f, Vector2.down, .1f, jumpableGround);
}

[swift falcon]

So you have a rigidbody controller. These are perfect for physics interactions.

[swift falcon]

I see nothing that sets your X velocity

it's declared as dirX but I see no instances of it

I'm going to assume if physical materials don't work, that there's code somewhere that dictates if grounded + not "holding A or D" velocity is set to 0.

Ctrl+F and highlight everything that mentions "dirX" and have a look

This is where the fun of making something both slide and stop on slopes comes in

hey so im trying to check if the camera can see the player or not and i use a raycast. now even though the player is behind a wall the camera still returns true... is there something im doing wrong here?

[swift falcon]

You're casting the ray with playerMask

[ebon apex]

yes?

[swift falcon]

that means the ray will collide with only the player and not the walls

[ebon apex]

thats the point

[swift falcon]

you'd need to add walls to the layermask and then a separate check for if the object it hits is the player

[ebon apex]

oh waIit so it will ignore the walls?

[ebon apex]

aah okay

thanks

[swift falcon]

you can use this same strat to add glass to a separate layer that is not on the cameras layermask so the beam will ignore glass and detect you

Can someone help with making a parallax? I'm trying to use Dani's tutorial, but i cant get the objects to reappear, once gone off the screen.

public class Parallex : MonoBehaviour {

    private float length, startPos;
    public GameObject cam;
    public float parallexEffect;

    void Start () {
        startPos = transform.position.x;
        length = GetComponent<SpriteRenderer>().bounds.size.x;
    }
    
    void FixedUpdate () {
        float temp = (cam.transform.position.x * (1-parallexEffect));
        float dist = (cam.transform.position.x*parallexEffect);

        transform.position = new Vector3(startPos + dist, transform.position.y, transform.position.z);

        if      (temp > startPos + length) startPos += length;
        else if (temp < startPos - length) startPos -= length;
    }
}

I think its because i dont have the object in the sprite renderer,

its like this instead

[dull glade]

Ok so this is what I got, I basically want the ship to play a different animation if it is moving perpendicular and in a certain direction from its current orientation as the digram shows. Not sure how to setup the math to get this working.

[pale spindle]

Good morning, hope all is well. Is there anyone who is good with the Slider control in the UI? I have 2, one for music, one for sfx. Audio Mixer works fine so the sounds are there but the sliders do not reflect the volumes. Not sure if anyone can assist in #📲┃ui-ux or not.

[hexed pecan]

You can compare its forward direction with its velocity

For example, Vector3.Dot(transform.forward, rb.velocity.normalized)

Or Vector3.Angle

If it's 2D then you probably need to use transform.right/up instead of forward

With dot, moving sideways will give you 0

Backwards will give you -1, forwards is 1

[late lion]

Volume sliders need to be logarithmic, because our sense of loudness is logarithmic.

[pale spindle]

I posted the entire thing in #📲┃ui-ux if you can check it out, I appreciate it.

Also its a 2d game so doesnt need crazy things

[dawn nebula]

What's the standard practice for teleporting a rigidbody with interpolation?

[swift falcon]

Interpolated teleporting?

So flying?

usually lerp timedeltatime if it's what i think you're asking

[leaden ice]

rb.MovePosition

[dawn nebula]

Sorry let me rephrase that. The interpolation setting on the rigidbody is set to Interpolate, which smooths the movement across frame updates.

I just want to teleport the object to some new location.

Effectively ignoring interpolation for that movement.

[swift falcon]

like Praetor said

[dawn nebula]

https://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

Rigidbody.MovePosition moves a Rigidbody and complies with the interpolation settings.

But I don't want this.

Teleporting a Rigidbody from one position to another uses Rigidbody.position instead of MovePosition.

alright then

[swift falcon]

I always thought that was readonly

🤯

[dawn nebula]

The transform will be updated after the next physics simulation step. That's kind of a pain.

Kinda wish setting the transform would just... disable interpolation for that frame.

[hard viper]

setting rigidbody position is very useful

it’s like moving the transform, but all the colliders and rb internals get updated

[leaden ice]

You said you wanted interpolation

If you don't, then just use RB.position

[hard viper]

why can structs not inherit?

[swift falcon]

https://stackoverflow.com/questions/2310103/why-c-sharp-structs-cannot-be-inherited#:~:text=Because it is the way,method table pointer allowing inheritance.

They go into detail here

It's essentially to do with value types in .NET

[leaden ice]

Because pointers are always the same size but copying by value is impossible without knowing the exact size of the thing to copy

[vapid condor]

structs can inherit interfaces tough

[leaden ice]

implement, not inherit

[vapid condor]

yeah my bad

[hard viper]

i just imagine the compiler could just try to define a value type of a child struct by getting together all the methods/fields, and creating the structure for the child value type

but i guess that just isn’t how it works

[leaden ice]

Yeah but when you pass it as a parameter to a function the function needs to know how big everything is to organize the stack frame. Not possible with variable sized parameters

No inheritance means the memory size of the struct is known at compile time

[hard viper]

that makes sense if you have a class inheritting from a struct, but if you have a struct inheritting from a struct, then the compiler should be able to figure out the size of a derived struct. it would be a compile-time const

[steep herald]

There's a version of physics2d.raycast that returns a raycasthit2d. How is this meant to be used in order to check whether or not there was an actual hit?

See if the transform contained is null?

[hard viper]

sizeof(Child) = sizeof(Parent) + sizeof(Child’s fields)

[leaden ice]

The same function can be called with differently sizes structures though

Which won't be possible

[hard viper]

“This function returns a RaycastHit2D object with a reference to the Collider that is hit by the ray (the Collider property of the result will be NULL if nothing was hit). “

[steep herald]

Ah, thank you. They could have added a convenience property

[hard viper]

you don’t usually want to use Raycast tho, imo. It is more common to use one of the nonalloc methods that grabs an array to populate a collection. this way you can sift through/filter results

those methods return an int as the number of hits

[steep herald]

are they ordered ?

[hard viper]

no

if you output to a list, you can sort the list based on whatever criterion

such as by distance

[steep herald]

ah hit.distance is exposed

Okay, sweet

thank you

[hard viper]

👍

[hard viper]

oh, i think i see the issue now

ty

[hard viper]

btw, you probably also want to know about Collider2D.Cast

the cost for a single boxcollider .Cast is almost the same as a single Raycast call

I have a world that I'm trying to render in isometric, blending 3D and 2D. I found using the camera at an isometric angle introduces a lot of pixel jitter and other subpixel issues due to the math of the camera being rotated. One solution I have found is rotating the world itself fixes every single issue I have, keeping all the objects on a nice, aligned, 2D plane for the final render. The only concern with this is that it makes workflow pretty unintuitive since the engine is obviously not designed for worlds to be rotated. What would be the best way to rotate the entire world(in this case a nest of GameObjects all under a single "Terrain" parent object) in a way that is only visual, during runtime? Methods I've tried:

• RenderPipelineManager.beginCameraRendering and rotating the gameObject during render and then undoing the rotation at RenderPipelineManager.endCameraRendering. This has gameplay implications though as it rotates the entities around they don't always end up in the same position in the world as their pre-rotated counterpart. Using a navmesh for example, a character may be at the top of the stairs in the editor but during runtime as the object tries to find itself among the navmesh, snaps it to the bottom of the stairs.
• Shaders. I know shaders don't have any effect on things at a gameplay level, but I'm not sure how to rotate an entire nest of objects on the same pivot(aka keeping the whole world together as it rotates) since all the objects will just rotate around their own pivot instead of their parents.
  Any advice would be greatly appreciated

[polar marten]

pixel jitter
are you saying you are trying to render 2d pixel art in an isometric world

[radiant marten]

2d pixel art in a 3d isometric world

[polar marten]

there is an asset called Ultimate Isometric Toolkit which includes a simple sprite material to orient the sprites towards the camera and pixel-align them

which is all you need. you should definitely lay out your world naturalistically in the xz plane, and orient your camera in the projection you need (isometric, although you probably mean dimetric 2 x 1)

[radiant marten]

I have the sprites orienting fine, but if the camera is not perpendicular to an axis it introduces a ton of jitter that I have not found any asset able to resolve

[polar marten]

are you trying to use the pixel perfect 2d script from unity?

the asset i am discussing resolves pixel alignment issues in the absence of pixel perfect 2d, which you cannot use

for a non-orthonormal projection

[radiant marten]

I've tried the pixel perfect camera, I've tried a few assets that are supposed to do it. While they all alleviate the jitter to a degree it's never to the precision I need

[polar marten]

i am saying you cannot use it

[radiant marten]

I said I've tried it, not that I'm using it

[polar marten]

gotchya

well that's all you have to do. the asset is $30. you shouldn't do any of the stuff you are discussing, although you could try authoring the shader it uses

[radiant marten]

https://assetstore.unity.com/packages/vfx/shaders/fullscreen-camera-effects/propixelizer-177877 is another one that I've used because it also has specific scripts to fix pixel jitter in 3d

[polar marten]

this is coming from someone who makes a dimetric pixel art game

[radiant marten]

and it helps, but it's still there, just less so

[polar marten]

do you have a screenshot of you game?

[radiant marten]

unfortunately under an NDA so I can't post much about it

[polar marten]

the problem you are describing cannot be solved in a general way

which is perhaps valuable to know

however, you don't need jitter at all

[radiant marten]

well like I said, rotating the world solves everything. I just can't figure out how to rotate it in a way that does not effect the game

[polar marten]

because you don't need to enforce alignment

you know, go ahead and do that then

I just can't figure out how to rotate it in a way that does not effect the game
so you see what i mean by not general

[radiant marten]

shaders seem like the go to but I can't seem to rotate entire nests of game objects around a single pivot

[polar marten]

can you show me an example of a commercial shipping isometric pixel art game built in unity that lays out the world naturalistically in 3d and attempts to align every art pixel exactly to a canvas pixel?

you will not be able to find one

my suggestion is to not do that, because no one will notice

[radiant marten]

also can you link this because I'm not finding anything by that exact name

[polar marten]

it cannot be done in a general way. however, the ultimate isometric toolkit does it 95%

[polar marten]

unfortunately it looks like it's gone... 😦 https://code-beans.github.io/Ultimate-Isometric-Toolkit-Docs-and-Issue-Tracker/

[radiant marten]

I'll get a screenshot once I swap out sprites

annoying unity gets hung up in the package manager all the time now

[polar marten]

so let me explain why this cannot be solved in a general way

for starters, this can't be solved in a general way with an ordinary orthonormal pixel art game either

the problem is just a lot less pronounced

as long as you want to do something in floating point and that's moving, like physics, a general approach has to have an answer for how to align a piece of art to the screen in a way that interacts correctly with another piece of art. if things can have non-integral speeds with respect to screen space, which is always for dimetric projections and frequent for ordinary orthonormal projections, you will have one of jitter, stretching, or irregular pacing

you don't see pixel alignment issues in retro games, but they have all painstakingly eliminating movement pacing issues, primarily by not using naturalistic physics at all

you can't have no issues because, you know, the rules for Ideal Pixel Art world can't be reconciled with naturalistic physics

do you know what i mean by irregular pacing? like characters have to move an integral amount every frame to appear to be moving smoothly with constant velocity, but with naturalistic physics, a speed of 2.5 pixels per frame means sometimes it moves 2 pixels, and sometimes it moves 3. it's just that with a dimetric project, it is always moving a non-integer number of pixel art canvas pixels per frame, whereas with ordinary 2d projection, you can control it

[radiant marten]

the issue is that in 2D you can easily round floating values for precision. But because of the math involved with a rotated camera you can't just round stuff. As you walk around, sprites get rounded at different alignments to your character/camera due to depth/rotational math etc

[polar marten]

what people do is they do not align to the pixel art canvas while objects are moving, which includes when the camera is moving, so the answer is sort of that they don't stress too much about alignment at all

yeah i agree with you there is no general way

[radiant marten]

so even snapping things into position in screen space doesn't really matter because things like this:

[polar marten]

you should not try to align generally

[polar marten]

i think this looks good

[radiant marten]

it doesn't look good though, none of the pixels are aligned and as you move, due to this, everything wiggles

[polar marten]

don't try to align while things move

[radiant marten]

that's why rotating the world works so well, I just need to find a way to rotate it with a shader

[polar marten]

which means don't try to align

i think you are on the start of a long journey, and maybe you will arrive at the same place i did

[polar marten]

do you understand what i am saying about movement pacing?

[radiant marten]

well I've been messing with this for half a year

here is a view with the camera rotated

[polar marten]

yes, that is what i mean by movement pacing issues

it doesn't matter how the world is rotated

if you rotate your world, as you're describing

and in order to not have movement pacing

you will have to use different physics altogether

you will still have these problems with 2d sprite physics

because the underlying issue is that there's no general way to reconcile a non-integral amount of motion per frame with an aligned pixel art canvas

you have to choose your demon: either you have movement pacing, jitter or non-natural physics

imo, do not align

you don't need to align

nobody notices alignment issues

[radiant marten]

this is very noticable

even Ubisoft releases games with animations jumping between 30 and 60 fps

[radiant marten]

here is the world rotated

[swift falcon]

it's noticeable to you because you made it

[radiant marten]

and here is the final render

[swift falcon]

it's the same with every artist and their work. it's the drive for perfection

perfection is not ascertainable

[polar marten]

okay well you see what i mean by movement pacing issues
