The math works just fine on the CPU, which is what I wrote it for originally, but even after trying a bunch of different methods, I still can't get it to work in compute

sly grove
#

Write your intermediate results out to computebuffers and print them out in cpu world

round pawn
agile yoke
#

I've used that to good effect for figuring out where my compute shaders are going wrong; allows stepping forwards (and backwards) by individual statements or instructions, inspect intermediate values, etc.

#

Fwiw, the link Mindstyler sent earlier is basically the same thing but using Visual Studio instead of RenderDoc. It is specifically about debugging compute shaders, so you might want to have another look at that too instead of dismissing it because it has "graphics" in the title

I am repeating this process quite often, and open to ideas on how to make this more streamlined in the editor:

  • Add a TextMeshProUGUI to my scene.
  • Add a public variable to the (only) script in the scene with the same name.
  • Link the object in the scene to the variable.
  • Add a line of code in a method called LocalAssert(): Assert.IsNotNull(MyNewTextObject);

It might not always be a tmpro object, sometimes it's a button or progress bar or whatever, but the above is tedious.. would love a way to automate it or put it into an editor popup of some sort. Any ideas?

I just did the above about 400 times 😐

I'm trying to load a prefab from SteamVR in a Kerbal Space Program mod. When I included SteamVR.dll alongside my own mod DLL, it throws this error when trying to load the assetbundle:

937 [LOG 13:30:05.198] [FirstPersonKerbal] Bundle: vrplayer, Asset: assets/steamvr/interactionsystem/core/prefabs/player.prefab
938 [WRN 13:30:05.855] The script 'Valve.VR.InteractionSystem.Player' could not be instantiated!

Without SteamVR.dll, the assetbundle loads but the script components are missing

Am I compiling SteamVR.dll wrong maybe?

I'm wanting to just use portforwarding to have my own servers.

drifting galleon
#

i recommend dedicated servers

gilded prism
#

I wanted the servers to be more along the lines of how MC handles it.

drifting galleon
#

minecraft are dedicated servers

gilded prism
#

Not all. Minecraft has all sorts of server styles.

drifting galleon
#

all. except if you play over lan only

gilded prism
#

You can portforward your own server for MC, and pretty easily at that.

thin mesa
#

minecraft uses listen servers for singleplayer/LAN and dedicated for everything else. Unity's Netcode for GameObjects can do both and is actually super easy to get started with. I haven't personally tested it with anything super complex yet but it's pretty decent

#

port forwarding is also not related to the server implementation, it's something you do on your router to ensure the port the server uses is available for outside connections

gilded prism

Alright, well none of that even matters now because I just remembered I got a new PC

This is causing your check if zAxisRotation (which is decremented by 180 every frame) is < =360 to evaluate to True within 3 frames and reset the rotation to zero. I would probably do something like zAxisRotation = Mod(zAxisRotation + 180, 360) to continually keep your rotation values within range. I haven't played with Quarternions too much but you could also probably just rotate that and let that take care of normalization of the value.

I've imported an asset called Grapher, something to help with debugging. I can't access it though because it sits outside my Scripts folder's assembly definition. I'm new to using them and still trying to get the hang of it. How should I add it to the reference? I know I can make Scripts reference it and let that trickle down access, but I figured I'd ask since this is meant to be something fairly global scope.

This script draws raycasts around the center of a space ship, I'm trying to get it so that the rayRange is equal to the magnitude of velocity in the assigned direction, would anyone know a way to calculate this? I thought of using the rigidbody.velocity.magnitude * direction but that would essentially just make all rays equal to the magnitude.

      for(int i = 0; i < numberOfRays; ++i){
        var rotation = this.transform.rotation;
        var rotationMod = Quaternion.AngleAxis((i / ((float)numberOfRays - 1)) * (angle * 4f), this.transform.forward);
        var direction = rotation * rotationMod * Vector2.right;
        Gizmos.DrawRay(gameObject.transform.position, direction * rayRange);
      }
    }```

project the velocity vector onto your direction vector and use the result to draw your ray

Found this while replying to something on reddit. Just thought I'd drop it in here - I think its an absolute must-read if you don't know anything about CPU caches. It goes into some of the reasons why DOTS exists (or is starting to exist) but I would argue it is actually more relevant for those NOT using DOTS because the whole point of DOTS is so that you don't have to think about this....

Some surprising things like a case where an array of pointers is less efficient than an array of copys because it uses the cache more efficiently.

Just really well written:

for destroyed objects I assume
(object)someGameObject == null is true?

No

#

not asking because I fancy that style but because I stored a GameObject as a object

#

hm yeah I guess it makes no sense
so best I should do (GameObject)someGameObject == false (if in this case someGameObject was stored as object) to check destruction?

I used to do a lot of throw new Exception(..) in the past. Cause I generally like fail fast

I'm eyeballing myself, why is it that the Build behaves differently than my Editor for my Behaviour Tree!! Is there someone willing to take a look at my Behaviour Tree code to help me, because I'm lost

#

The problem follows: In the editor the game runs fine, the AI (Chickens) behave properly. When building the game this all turns. Suddenly the Behaviour Tree used for the AI becomes very unstable, making the Chickens run into invisible walls or making them go off the NavMesh, and this only happens in the Build.

I have a list containing DIFFERENT subclasses that all derive from the same base class. When I iterate through the list, how can I tell what the subclass of each item in the list is so I can cast it properly?

coral folio
stark shore
#

only "delay" shows up but each subclass has many more methods.

unknown.png
#

Which makes sense, since i am iterating through by base class

coral folio
stark shore
#

I have a custom inspector and i can add any subclass I want. So when this particular action is run, it can literally be anything in there

unknown.png
#

But is there a way to figure out what the subclass of the currently selected script is?

#

even though i found it by base class?

coral folio
#

This is the heart of the Liskov Substitution Principle. Don't do what you're doing; do it in a way that the method that can operate on the base class, can operate on the subclasses. Or they're not subclasses anymore.

stark shore
coral folio
#

If you're figuring out what subclass it is and casting it to call specific things, you're doing it wrong. But ydy.

You only operate on the common aspects of them. If you want to ask them all to do something, you implement a method, 'DoSomething()' that you can blindly call. In short, if you have a collection of the base class, you only should call methods that are defined by the base class. If you want to add functionality that is used by code that will only have the base class available, you need to add it to that base class.

So your code looked like it was trying to do something with 'position' and 'target', so those seem like things that the base class should implement.

A foreach loop preferably, followed with a switch statement with pattern matching inside of it, if you want to access members on some derived classes

#

You are, with pattern matching you absolutely can.
But, it would be better to have a common denominator like an abstract method or property in the base class that all inherited classes implement

#

So you don't actually need to modify the switch statement everytime you add a new inherited class

stark shore
#

I have an enum in the base class. Is that sufficient? (sorry for the questions. this particular thing is pushing beyond my C# knowledge)

# 

[System.Serializable]
public class Action_Series
{
   [SerializeField] public float delay;
   public SubClass subClass;
   public enum SubClass {
      PositionTween,
      Animation,
      Prefab
   }
}```
coral folio
stark shore
#

Ah! that I (somewhat) understand

#

So the abstract is null unless that subclass fills it?

coral folio
#

Well, the subclass must fill it in; but it can return null if it wants to.

#

Well, okay, you can define it virtual and then have a default implementation that returns null, for instance.

stark shore
#

and then the subclass has to use an Override?

fresh salmon
#

Yes

#

I would gladly throw an example in, but mobile programming is a pain

coral folio
#

Here's a decent post about this that provides a pretty good example of abstract, virtual and a few other concepts: https://answers.unity.com/questions/1369097/question-about-protected-and-abstract-classes.html

Here are two subclasses of "Action_Series". In the switch, i want to check if the item in the list is a "Action_PositionTween" then it runs a tween and goes to the next item in the list. The next item can be another tween or can very well be an "Action_Prefab" where it instantiates something instead, or an "Action_Animation". And there can be many of them in the list.

Is this the current way im doing it (using a switch) the best way to do this? or do you know a better way?

@coral folio @fresh salmon

Thanks so much for your time (its 6am where i'm at). The pattern switch suggestion and link you provided i think put me in the right direction. I don't think i have it yet but it definitely gave me a start to help write it better

unknown.png
coral folio
#

Seriously, if your code had ANYTHING that it was actually doing with the data, I might be able to suggest a better way, but your code is completely devoid of any details, unfortunately.

stark shore
# coral folio Seriously, if your code had _ANYTHING_ that it was actually doing with the data,...

I'm in the middle of rewriting the spell system completely unfortunately. So i'm back at square one. The intention is, in each of these switches, i run a coroutine that either:

Tweens the caster (or target) to a position, runs an animation, or instantiates a prefab somewhere. It's meant to be modular, so i can add as many tweens or prefabs i want and have them all executed from this single action, using the coroutine for delay timing

#

If this switch actually works, you've basically solved all my problems. When i had it working before overhauling, everything after the switch worked well

#

and..... it does! fantastic

unknown.png
coral folio

So...why not have a method DoYourThing so the loop goes, item.DoYourThing() and have the item itself do all its work?

stark shore
# coral folio So...why not have a method `DoYourThing` so the loop goes, `item.DoYourThing()` ...

Because if i include everything in the base class, i started experiencing a LOT of bloat. Every one of the items in the list contained every option even if all i wanted to do at the current moment was a single tween. And if i wanted two tweens? i needed to add two of this base class with all these empty options and then write a ton of if statements to handle the null options. And then tell it not to tween if all i want is an animation.

unknown.png
coral folio
#

No...nononono.

stark shore
#

Basically its for sanity's sake

coral folio
#

No, you don't DO the work in the base class. You define a FUNCTION in the base class that is called DoYourThing and when you call item.DoYourThing() in the loop, the code in the subclass gets called. And it does it's work.

What I'm saying is that EVERY case within that switch is going to grab data from the item object, manipulate it, and do work. That code could be in a function in each subclass, and be magically auto-extensible, and the data and the code to manipulate that data will live together, where they should.

stark shore
#

Ah!

#

that's.... much better hahaha

#

much much much better

coral folio
#

That's what virtual and abstract are for. 🙂

stark shore
#

alright! I always felt like something was wrong. I had a folder of 12 different classes just to do actions. this feels like it will be better

coral folio
#

nodnod I think it will; unfortunately I need to wake up in 3 hours, so...I should get a little sleep. 😛

I imagine your loop should end up looking something like:

foreach (Action_Series item in action.series)
{
    item.PerformAction();
}

Or whatever method name you end up choosing. Best of luck!

@rapid sky I think what you're confronting is how to model categories in code. How I interpret your 'same script' question for the weapons and the enemies is you gesturing at a desire to deal with enemies in a generic way, and separately to deal with player weapons in a generic way.

When I model categories of things in my code, I usually model it using an 'abstract interface' modeling technique. Sometimes I model it using a base class, other times I use an interface, and still other times I use an abstract class.

The challenge is figuring out what the common elements are across a category of thing. For example, a player weapon needs to be able to fire. No matter the type of player weapon, it will have to conform to that interface. The details of what it means to fire is specific to the abstract interface implementer

#

Same thing for the enemy -- you want to have multiple types of enemies but handle dealing with enemies in a generic way.

#

Rereading the diagram, I think what you're after too is defining how the weapons systems interact with the enemies. Most of the time, the player weapons are interacting with a health system.

Some advice: if you found yourself stuck for many months on something, ask yourself if you are still on track with your goals. It’s good to throw yourself at something difficult for your experience level because it helps you understand more.

But if you are trying to release something ASAP or something you may want to consider another strategy. You know you best— I’m just offering an opportunity to reflect!

I made a enemy script which attacks the player health when the enemy stands next to the player now i did a health ui and i wanna assign the damage function which the enemy does to the healthui script

#

But how

humble leaf
#

Just call a TakeDamage method on the player's controller script whenever the enemy considers it having hit the player. It can pass it's own damage amount and the player can handle the results.

hey so I was making a trigger so when it enables it makes the canvas active but it is not making it active

using UnityEngine;

public class showquestion : MonoBehaviour
{
    public GameObject OurQuestion;
        void OnTriggerEnter()
    {
        OurQuestion.SetActive(true);
    }
}

Hello!

I have a line renderer and I use it to draw things on 2D scene that disappear after a few seconds.

I want to introduce a “resource” which will deplete as I draw. E.g. it starts at 100 and it goes down to 0 as you draw. Then I also want this resource to increase passively (+X each Y seconds) and to have a pick-up that grants some resource immediately.

I’m quite new to line renderer, so I’m not sure how to approach this. Should it even be tied to Line-renderer dots or no?

Any advice is appreciated!

Here are the 2 scripts i'm using:
DrawManager - https://pastebin.com/pPGBVX4s
Line - https://pastebin.com/Ja8A8CFx

p.s. scripts are taken from a tutorial

Hello, is possible to make in c# a main function and then when i want to add code to it dynamic? like ```c
public void mainFunc()
{
.....
if(..)
{
here i want to add code dynamic
}
}

and then to have smething like

mainFunc({
GameObject.SetActive(false); or something idk
});``` sorry if i gave a bad example but idk how to really express about this

# hushed fable Looking to do something beyond strategy pattern?

i don't know exactly if i want to do that, i have a Database manager in my game and everytime i need a new thing related to the database, i need to write the same thing over and over just to add some conditions like in my code from above, like to have a code pattern with all the stuff and then just add some conditions, debugs etc

You want main func to accept parameters.. e.g MainFunc(bool state, int somevalue) so you can make it reusable

IEnumerator CheckUsername(Action callback)

I'm trying to find out how to create a polygon using code, apply a texture to that polygon, and add a 2d collider to it, but I can't find any information on it. I did this a couple years ago so i know it's possible but I can't find any information on how to do it.
My goal is is to slice a texture that will act as a TileMap, and then create a 2d mesh with collisions to act as terrain

How does 'Wait Until' work?

yield return new WaitUntil(() => loadedPrefab != null);

In a coroutine, does it pause the coroutine until loadedPrefab is no longer null, or does the coroutine need to be run again?

undone coral
junior ravine
undone coral
stark shore
undone coral
#

hmm

#

() => loadedPrefab != null is a method

stark shore
#

because of the lamda?

undone coral
#

it's a lambda expression

#

it's a piece of code

#

it will get executed every frame at most

stark shore
#

What if i just did
yield return new WaitUntil(loadedPrefab != null);

undone coral
#

that wouldn't work

#

it will show an error

stark shore
#

Thats the part i dont udnerstand

undone coral
#

that's what i thought

stark shore
#

I am getting an error

undone coral
#

it's telling you what the issue is

#

WaitUntil accepts a Func<boolean>

stark shore
#

AH! i need a function that returns the value. THank you

undone coral
#

hmm

#

yeah you do

#

but a lambda expression, a method and a function are all sort of the same thing

stark shore
#

oh...

#

Then im back to not understanding why its not working lol

undone coral
#

yield return new WaitUntil(loadedPrefab != null); is a syntax error

#

it's telling you that

#

the way wait until works is

  1. pause the coroutine
  2. call the thing you pass it at most once a frame
  3. if that thing returns true, resume the coroutine
# 
() => false
() => { return false; }

are the same, and might be more illuminating to you about what's going on

#

() => false and false are totally different

stark shore
#

That right there is the key

#

I dont get why those are different

#

is ()=> essentially a function?

undone coral
#

you can read about lambda expessions

#

yes, it's syntax for declaring a function

Gotcha. That makes much more sense now

Is there any solid reference on what I can do with Jobs on background threads and what has to be done on the main thread? I know I have to Schedule() on the main thread, but can I IsCompleted() or ScheduleBatchedJobs from the background?

#

Well yes, but none of those methods have anything to do with the scene/Unity Objects

drifting galleon

drifting galleon

#

... i doubt no ones ever figured this out lol

undone coral
#

what are you trying to do with Jobs

bright wind
#

That's a very detailed and long answer that's not really relevant

undone coral
#

okay i might be able to offer a simpler solution

#

that performs as well

#

not as an alternatiev to jobs

#

but for example, why you'd want to call a unity job from a different C# thread, or how you're expressing dependencies between jobs

#

i think the jobs api is thread safe

#

maybe just a brief answer?

bright wind
#

I'm not looking for architectural advice - I know how to architect code. I need to perform a lot of jobs and the divvying up of tasks into jobs needs to be background threaded on it's own. I just need to know if I can safely check their completion and such tehre as well or if I need to keep posting back to the main thread. A simple "yes" "no" or "i don't know" is totally fine. But I'll take the latter and get to writing my own tests since no one here atm seems to know

undone coral
#

hard to know though without knowing what you're trying to do

violet schooner
#

he's talking about the unity job system

undone coral
#

wonder what it could be

bright wind
#

That's entirely irrelevant and extremely pedantic of you to assume I need help architecting code

#

I asked a simple question about a single API, not your advice on software design

undone coral
undone coral
#

bright wind
#

That's still not my question. One would hope multithreading apis are thread safe

undone coral
#

IsCompleted is thread safe

#

you can call it from any thread

violet schooner
#

just jumped in, but short answer is, you have to keep checking from the main thread if the job done.

undone coral
#

it's documented in the source

bright wind
#

undone coral
violet schooner
#

jobs needs to be background threaded on it's own
Jobs itself can't be scheduled in a background, it has to be mainthread

undone coral
#

ScheduleBatchedJobs also is thread safe

@bright wind I should probably ask later (since the conversation heat seems to be unfortunately up) but… First, can I say I like your avatar? Cats in pictures are always fun.

Second, and this is just me being a curious programmer. What is your use case for using background jobs in unity? I’ve used the technique in my software engineering work for bigcorp quite a few times but I haven’t really found a use case in Unity. I know you may be busy but I would love to read what you write. I agree it isn’t relevant to your question but, just me being a curious programmer.

undone coral
#

i also can see how, if you come from a software engineering background, if you are developing games for the first time, unity can be really frustrating. there's a lot of stuff that doesn't matter much in game development, like package management and tests and c# language features, but matters a lot in app development or whatever people use C# besides this nowadays.

bright wind
#

Again, entirely off topic to my original question. Plus I've been doing game dev for 10 years. And no real serious app development uses C#. Move on dude.

#

This isn't your soap box

undone coral
#

and people coming from those backgrounds will feel frustrated. especially a web development background, where libraries can be bad but also you don't pay for any of them, or from a backend engineering background, where a lot of stuff is generally engineered better than in games. this is all okay

lol

#

the mudbun source is a great example of backgrounding using compute shaders, it doesn't use jobs

#

in unity packages they use it really well for something like Sprite Shape 2D

#

since UnityWebRequest backgrounds for you, a lot of the stuff you'd see in normal apps you wouldn't need to do in unity

#

since most normal apps, their background work is waiting for a web response (IO)

is this guy actually a mudbun bot?

if you were creating some kind of diablo-style game with procedurally generated dungeons, laying out a dungeon could benefit from parallelization. on the other hand, dungeons that are gameplay-fun tend to follow simple enough rules that generating them is pretty fast on a single thread. it's hard to say if it matters, the difference in time. meshing a whole world is something that is pretty challenging, and yes would be an appropriate background task, but you won't necessarily do that much in untiy

violet schooner
undone coral
#

i think i'm answering the question here

#

it would be interesting to see what a game like No Man's Sky does. the toughest thing is translating a nice looking approach, which can be serial by design, into something that can be parallelized

#

for example, most dungeon generation is not parallelizable, it is serial by design. but it also looks good

#

marching cubes are one of the voxelization approaches that are paralellizable

simple badge
#

Two independent dungeons can easily generate in parallell

undone coral
#

yeah so it's pretty specific

simple badge
#

It all depends on the use case

undone coral
#

marching cubes are exciting because they look good though

#

like composing a bunch of primitives in booleans

#

is a good design language for normal people, and is easy to parameterize

#

and turning 3d shapes in an abstract sense into a smooth mesh is possible with marching cubes

#

in real time

#

that's why people are so excited

#

whereas go straight from some kind of design thinking to vertices is much harder

#

you'd have to simultaneously figure out how to turn your idea into a mesh, and then also make it parallel

zenith ginkgo
#

what is going on

undone coral
#

i don't know, i'm answering a different question

#

this is what Jobs is good for

zenith ginkgo
#

doesnt look like it

undone coral
#

doing something like magica voxel in real time

#

it's a really cool program

#

making libraries

#

that's where you'll see it

simple badge
#

Jobs are generally for stuff you don't need in realtime though

undone coral
#

hmm. but look where it's used in unity libraries

#

sprite shape 2d => for the best performance, to make realtime lines. it's true you will generally not want to do that, but that's the point

#

physics => realtime

#

usually to make procedural graphics generation fast enough to be realtime

#

otherwise you'd use another tool. you'd just use Maya or whatever

bright wind
#

I asked the question, and as I've said like 4 times, you're no where near my question at all. You're not answering any question. You're just ranting.

undone coral
#

you'd bake it. if your goal wasn't realtime/runtime, you could get it from a backend and use a purpose-built tool

I don't doubt people use it as a quick and dirty way to do something on another thread

undone coral
#

i think those have already been solved a while go conventionally

#

hmm

#

well what would they do? make a web request? this is what i mean

#

im just trying to explain the real evidence, which is actual searchable code that reference Jobs

#

it's a good thought though

simple badge
#

Heavy tasks where you don't care about timing

undone coral
simple badge
#

Like chunk generation in minecraft

undone coral
#

that's all?

simple badge
#

You don't care if its done in 1 or 100 frames

#

As long as it gets done

#

For realtime stuff, timing does matter

#

And as such it is not ideal for jobs

undone coral
#

minecraft predates Jobs. but all we're really saying is that, minecraft isn't that interesting to clone anymore, so of course there aren't going to be that many libraries trying to do it performantly 🙂

undone coral
#

i think maybe because you use jobs and burst together, and it has a very good way to interact with native memory like meshes and textures

#

it appears in realtime everywhere

#

you can even just turn on profiler and see it

#

used by unity packages*, in realtime cases

#

across multiple backgorund workers

#

if you dont' care about timing, you wouldn't bother right?

#

would anyone care about chunk generation if not for minecraft? it's pretty hideous. does it appear in many 3d games? there's terraria in 2d sure, but you don't need to parallelize manipulating the tilemap

#

anyway just something to think about

#

i don't think anyone uses it for quick and dirty background

violet schooner
#

you're missing the point of using Jobs.
Jobs is used to process large amounts of data.

Marching cubes for example.
If you want to move 10000 cubes, on main thread that's going to tank performance.
however with jobs, you can offset that to another job thread and leave your main thread open for other stuff.

A* pathfinding is another. And since we're on the topic of libraries that you keep talking about.
the beta for A* Pathfinding Project asset are in the midst of digging into the job system to offset calculating the path.

simple badge
#

If something takes more than a few milliseconds, you need to run it on another thread or you will block the game loop

undone coral
#

like pathfinding is interesting in real time

#

it's a great example

#

you still want it to finish in a few millisceonds, that's yoru goal

#

you're using the framework to parallelize it

#

marching cubes -> a graphics approach

#

you wouldn't try to parallelize directly meshing some terrain generation

#

meaning, people do stuff on here all the time

#

where they like, drop physics objects and make raycasts

#

to generate terrain

#

or whatever

simple badge
#

It doesn't have to be parallellized

#

With itself

undone coral
#

i'm trying to answer the question why you don't see jobs used more

#

yeah

#

or any background threading

simple badge
#

You don't see them used more because you don't see the code of the big scale games

undone coral
#

because while those approaches are low tech, they can look good

undone coral
#

graphics effects reign supreme. nowadays for things like realtime volumes

#

I mean you have to distinguish between realtime and "realtime"

Is there a way to make Pixel Perfect Camera with Upscale Render Texture true NOT snap the camera to a grid, only the sprites? The problem with that is that camera movement becomes jittery.

Alternative question: Is there some way for a Camera's rect/pixelRect/Viewport Rect to have values outside the true screen? Unfortunately whenever I try to set the viewport to cover an area bigger than the screen, it gets clamped to the just screen.

#

Traditionally without an engine, I'd render the scene to a render texture that's 1 pixel bigger than the reference resolution, and draw it upscaled onto the screen with an offset depending on the camera's sub-pixel position. That seems to be impossible in Unity since trying to draw outside the screen results in squishing the texture to fit in the screen.

simple badge
#

you're rendering to a render texture

#

so the screen resolution does not matter

#

make the render texture "1px bigger" if that is your desired solution

cold surge
#

I'm trying to render that texture back to the screen, upscaled. That's where my issue is.

simple badge

that'd be a quad and an ortho camera

Hm I hadn't considered creating a quad with the texture and rendering again. I'll try that out.

If you texture is 128x128, lines 9 and 12 are wrong

hallow elk
#

But it's a reflection probe. It should be 128 * 768

#

There's 6 128px textures

long ivy
#

then line 12 is wrong, and I'd expect that error to be from SetPixels and not GetPixels

#

no sorry, line 9 is the wrong one after all

#

your texture is only 128 pixels tall, so a rect of (0, 128, 128, 128) will fail

hallow elk
#

So this is the idea. I am trying to get the first 128x128 square of the reflection probe, and swap it with the second 128x128 square.

I get the same error if line 9 is Color[] samplePixelsuX = oldFrostedTex.GetPixels(128, 0, 128, 128, 0);

I have 2 C# scripts I am trying to package as DLLs to share. The issue is, one of those files is a ScriptableObject. Though I am extending it, it seems when you build the DLL.. somehow the script is still a mono script?

}

When I build the DLL and import it, you can see the two classes. (image 1)

However, if I click on the one script that is a scriptable object, (image 2) you can see it shows as "mono script"

I am also getting this error from the console:

CreateAssetMenu attribute on Thermal_Body_For_Unity.ThermalMaterial will be ignored as My_Namespace.ThermalMaterial is not derived from ScriptableObject.

Is it maybe not possible to do this?

Yay! I'm glad it works. I apologize for not being clearer earlier; I think I'll call out explicitly when I'm talking about unity monobehaviour life cycle methods in the future. Thanks for the opportunity to improve!

Not sure if you have seen this manual page yet but it has a really cool diagram that explains different types of lifecycle methods and when they are called by the engine. https://docs.unity3d.com/Manual/ExecutionOrder.html If you haven't seen it before it may inspire you while you are making your awesome game.

#

In fact, I'm re-reading it myself. So clutch. So fire

burnt shard
#

less than ideal but I don't think unity provides an ideal solution here

crystal ridge
#

So, I have a bunch of particles in my Resources folder. Instead of instantiating them as I need them, I'm instantiating them all at the beginning of a scene and putting them inside of a List<ParticleSystem>, the idea is to instantiate a duplicate of the existing item in the list as a way to reduce the frame drop of loading from resources every time I instantiate a new particle I need, each particle also cleans itself up, so i'm not worried about GC.

What is confusing me though, is this function I have keeps returning 2 of my particles for some reason

public ParticleSystem InstantiateParticle(string name)
    {
        // this searches for and returns a particle if found
        for (int i = 0; i < particles.Count; i++)
        {
            if (name == particles[i].name)
            {
                ParticleSystem particle = Instantiate(particles[i]);
                particle.transform.gameObject.AddComponent<selfDestruct>();
                return particle;
            }
        }

        return null;
    }```
What am I not seeing here? I double verified that there's only one instance of each particle system in the list "particles" it's pulling from
# 
if (Input.GetKeyDown(KeyCode.P))
        {
            ParticleSystem p = particleManager.instance.InstantiateParticle("Spit");
            p.transform.position = Camera.main.transform.position;
        }

This is how I am testing it, and it returns 2 particle systems every single time, and I'm stumped

lost crest
#

i think you may need to look into pooling. this is what you are doing however. you are instantiating them and putting into list and then instantiating them again, which is the wrong way and possibly still adding to GC... once in the list just move that one where it needs to go and enable it, then disable it. put back into list for use later. Look up polling. im sure there are tons of yt videos on how to implemet it correctly.

#

Using pools is if you only need one type of object from the list at a time and many duplicates of same object. But im sure you could convert the basic polling into what you need. sounds like a list of different objects need to be pooled somehow. If you only need them instantiated at start to keep GC and loading times down at gameplay. And only ever show one particle effect at a time. then it should still work.

#

so in your code just do this. dont instatiate a new one. move the one in the list and enable it. play it. then disable it. done.

#

maybe change name to PlayParticleEffect(string name, Vector 3 position) and have it handle enabling playing and disabling.

#

One more suggestion to add to the above message is that you should avoid resources for things like this.
Resource is meant for assets which are meant to be loaded on demand. If you're instantiating them at beginning itself, it will add some initial startup overhead.
For things like this, it's best to have a Startup scene with direct reference to all assets you need on a DDOL manager for each category. Like a ParticleManager script on the init scene with all reference to the assets which you can Instantiate at runtime.
Or look for addressable system, it's the best solution for problems like this imho.

crystal ridge
#

Thanks for both of your suggestions, I'll look into all of it, much appreciated

crystal ridge
#

And can I instantiate those from the manager as I please with less overhead than just instantiating from the resources folder?

You can serve your package through your git repo.

tardy loom
#

Fantastic

kindred tusk
#

But it's also possible to use a private repo if you don't wan to make it public

#

As an example... I just made a package that has my company logo (including assets and code).
In my manifest.json I add this line:

    "com.effortstar.effort-star-logo": "ssh://git@github.com/EffortStar/effort-star-logo-unity.git#v1.0.0",
tardy loom
#

Super neat. I'm just hoping to put a donate button or something similar

kindred tusk
#

That's a private repo

#

If you want to make it public you should 100% be using UPM. It's trivial to add your package to openupm too

tardy loom
#

GitHub sponsorships would be good too lol

#

I will do this 😃

kindred tusk
#

If you want donations I recommend adding the link to your README, but you can also be a little obnoxious and log out a request for donations when the package imports or after a project build

#

I know ink-unity-integration says "good luck with your release!" after you build.

#

You could use a build pipeline hook to do that.

#

You can also include assets in upm packages, not just code.

#

Including example scenes that can be optionally imported via the package manager

tardy loom
#

Oh I don't even want to annoy people like that. I'm cool with just if they do they do kind of thing lol

#

Including assets is perfect, because of the scriptable object, I actually need to do that

kindred tusk
#

Yeah, exactly.

tardy loom
#

Siiiick

kindred tusk
#

So when you're developing your package you'll want to add it as a local file system dependency

tardy loom
#

Ty so much 🙇‍♂️

kindred tusk
#

You can do this via window > package manager

#

That way you can edit the files as if they're in your project

tardy loom
#

I'm making, or have made, a thermal physics engine for unity. I'm fairly excited about it

#

For a cooking demo

kindred tusk
#

But then when you're done just push it up to its repo. If you add it to OpenUPM and add a tag it will automatically create a release

tardy loom
#

I have virtually cooked a steak to perfect doneness 😂

kindred tusk
#

DM me if you have any issues with UPM, I've done a few packages

#

Sounds delicious. Just need a 3D printer

tardy loom
#

I will! Ty!

# inland halo top one (Ancher) but how do i fix it

You're using a hard-coded string reference on line 50 to assign t_anchor. This can be pretty fragile. Looks like that assignment is not doing what you expect. Is there a Transform case-sensitively named "Root"?

#

I imagine you're calling Aim fairly frequently? I would recommend not calling Transform.Find in rapid succession, it seems unnecessary and (slightly) inefficient.

#

Why not assign t_anchor and those other references once every time the player changes weapons?

Yes

livid kraken
#

Like I said why can you do

{
     myTextVariable.text="cool";
}```
keen cloud
#

wait would taking out the public allow this?

#

or should this already work

livid kraken
#

No the public or private method does not matter

keen cloud
#

so yeah it dont work

livid kraken
#

Do you have more than one instance of the script in the scene where the reference is not set up

drifting galleon
livid kraken
#

Like a tmprogui or what ever why does that matter in the example ?

drifting galleon
#

oh i thought that was question of you

keen cloud
#

yeah every instance gives an error

#

but theyre all being called the same way

livid kraken
#

@KeyLocker shit Im on my phone and typed cant for some reason. You can do like what I showed in the example

drifting galleon
#

what's the error

livid kraken
#

Nre

keen cloud
#

object reference not linked to an instance or whatever

drifting galleon
#

then there is no instance associated with that field

keen cloud
livid kraken
keen cloud
#

is what i posted before

livid kraken
#

Cause this would be the only explanation

keen cloud
#

wym have its text field filled

#

im writing to it

livid kraken
#

Try do write t: ComPonentName where this is the name of the class and see how many components you have in the scene

keen cloud
#

i linked it through unity

#

the game object

#

its properly linked to the script

livid kraken
#

On every instance of the component in the scene ?

keen cloud
#

theres only one instance

livid kraken
#

Well I dont beleive you

#

Show me

keen cloud
#

it works without this

#

like

#

it works

#

i just want it to work without it being passed as an argument

livid kraken
#

And Im tellin you it doesnt need to be a argument

#

Try the t:ComponentName in the hierarchy search bar to see if there is only one instance of the component

Design tip, streams are disposable, so use a using statement to properly dispose of the stream whatever happens. Unclosed streams may cause issues later on, especially when a dangling stream locks access to a file, preventing other processes from accessing it.
The compiler warning might actually be telling you that:

using (StreamReader reader = new StreamReader(fullPath))
{
  // All stream-related operations go here
}
// Stream is closed here, whether the execution was correct or an exception was thrown.
keen cloud
#

oooo okay ill update my stuff

#

also i tried looking up your message about out Type

#

maybe i read through it too fast but thats supposed to work with what im doing?

fresh salmon
#

Yeah, I saw your question context posted here and realized it's not what you want

keen cloud
#

okay

livid kraken
#

You can manipulate that variable from inside the method just like that. That code at least in relation to the text field is valid

sage radish
#

The using scope can also be implicit:

using StreamReader reader = new StreamReader(fullPath);

It will be disposed at the end of the current scope.

livid kraken
#

Something else is fucking it up

keen cloud
#

its being called from another method

fresh salmon
keen cloud
#

also do u still do reader.close in the using?

livid kraken
#

At this point I want to look at your entire class

fresh salmon
keen cloud
#

cool

livid kraken
#

sigh put it in a paste site please

keen cloud
#

@livid kraken ?

livid kraken
#

chill Im reading it

keen cloud
#

man youre so intense lmao

livid kraken
#

does the error happen when you call it from ConfirmLanguage or when you call it from the menu ?

keen cloud
#

confirm

#

it works in start

livid kraken
#

so put a breakpoint at line 81

#

run the code and lets see the status of inputCode

keen cloud
#

any reason why it ignored the break point

unknown.png
livid kraken
#

you havent hit that breakpoint

keen cloud
#

i did tho

livid kraken
#

there should be a yellow arror at it and the code should stop

keen cloud
#

it threw an error on line 204

#

past the break point

livid kraken
#

breakpoints dont go through on their own

keen cloud
#

how do they work in unity then

livid kraken
#

I wanted you to stop on that line so we can look at the inputCode variable

keen cloud
#

yeah

#

it didnt allow me to though

#

it just went through it

livid kraken
#

so it skipped it ?

keen cloud
#

yes

livid kraken
#

so that part of the code is not being called then

keen cloud
#

but it must be cause the error is being thrown where the method is

livid kraken
#

did you attach the debuger ?

keen cloud
livid kraken
#

the play button in visual studio

keen cloud
#

this is my first project in unity lol idk

livid kraken
#

just setting a breakpoint wont do much if you dont start a debuger

hallow elk
#

Is there a way to reference the Build Scene list? Either as a List or as an Enum?

keen cloud
livid kraken
#

no thats for a build

#

I told you the green play button in visual studio

#

click that then hit play in unity

keen cloud
#

but all this is going to lead us to is a way to output from inside a method without passing the tmp as an arugment

#

so like

#

thats the answer

#

im just trying to find it

fresh salmon
#

Hmm, the green arrow in VS should be saying "Attach to Unity", make sure you have that

keen cloud
livid kraken
#

if its trying to start the project your VS is not configured probably so go to #854851968446365696 and configure it

keen cloud
#

its probably fine cause it works for everything else

#

i know this is just this one error

livid kraken
#

what you want is really basic there is nothing special about it something else is wrong with your code

keen cloud
#

yes it is basic

#

and it works

#

but not in this context

#

and i dont think its the visual studio configurations stopping it

#

i think theres a certain way to do it

livid kraken
#

there is no certain way you can access the variable directly in the method

#

or pass it as a param it does not matter

keen cloud
#

it works if u pass it tho

livid kraken
#

right now in the code you showed you are passing it and you are still getting a null reference

keen cloud
#

i am not passing it properly though

#

i mean of course cause im getting an error

#

but like im trying to find a way around this

#

i know the way around this i think but i want to find an easier way

livid kraken
#

my bet is still on having another instance of the component in the scene. I have to go now sorry

keen cloud
#

see ya l8r

#

@fresh salmon any ideas?

fresh salmon
#

Catching up, hang on

#

Alright, so as Uri said, we'll check for duplicate script instances.
In Start, paste the following line of code

Debug.Log("Script Start received", gameObject);

The second argument denotes the "sender" of the log, when you'll select it, the object that sent it will be highlighted in your Hierarchy

#

Just make sure Collapse is off in the Console settings

keen cloud
fresh salmon
#

So, only one log, and when you select it, the right GameObject gets highlighted in the hierarchy?

keen cloud
#

yes

fresh salmon
#

Same thing in Start, but this time log testCases

keen cloud
#

just one

fresh salmon
#

And the contents of the log, not empty?

keen cloud
#

same with input code

fresh salmon
#

Debug.Log(testCases) must not produce an empty message after the log timestamp

keen cloud
#

unsure what that means exactly but

unknown.png
fresh salmon
#

Yeah, so it has a value. No idea on what's going on here

keen cloud
#

:(

fresh salmon
#

It throws on this line, right?

testCases.text = reader.ReadToEnd();
keen cloud
#

yes

fresh salmon
#

Very weird. Just before that line, can you paste that code

Debug.Log(testCases);
Debug.Log(reader);

And ensure the first log says "TMPro.TMP_InputField", and the second one "System.IO.StreamReader"?

keen cloud
fresh salmon
#

Uhh, says "Null" now? Wtf???
So, it's getting de-referenced somewhere between Start and that point

keen cloud
#

yeah

#

lol but how do i reference it from inside that method

#

that was the question 🥲

#

lmao

fresh salmon
#

It should be working as is, what I don't understand is how it suddenly becomes null

keen cloud
#

cause im not passing it as an argument

#

im calling it from a static method

fresh salmon
#

I may have a solution, but you'll have to make the debugger work and attach to Unity

keen cloud
#

whats your idea

fresh salmon
#

Trying to break (stop app execution) when the contents of the variable changes

keen cloud
#

i dont think it changes

fresh salmon
#

It's a trigger you can make when using the debugger

keen cloud
#

i just dont think its pointing to the same variable

fresh salmon
#

Can you post the updated code again, so we're on the same page?

thin mesa
keen cloud
#

is there a way around this

#

is what im asking lol

fresh salmon
#

Ahh got it

thin mesa
#

yeah pass it as a parameter for the method or don't make the method static

fresh salmon
#

Variablefriend got me on the track

keen cloud
#

if you cant do either of those

fresh salmon
#

Your parameter and class field are named the same, so it prioritizes the parameter

#

You're actually never referring to the class field in that method

#

If what you wanted to do is bypass the parameter of course

keen cloud
#

i may need an explain like im 5 for that

# 
            submitCode.ConfirmLanguage();```
#

cause these are the same it doesnt work?

thin mesa
#

in a static method you can only operate on static members or things passed as an argument when calling the method. You cannot reference a non-static class variable inside of it. I also recall you showing SubmitCode is a MonoBehaviour which means you can't call a constructor with the new keyword

fresh salmon
#

From the latest version of the code I can see, the method isn't static

thin mesa
#

ah, i haven't actually seen any code recently. They just said it was a static method

keen cloud
#

the confirmlanguage isnt static

#

but its being called from a static method

fresh salmon
#

Yep, but no problem here, since you're creating a new instance of the class, and you call ConfirmLanguage on it

#

Wait

keen cloud
fresh salmon
#

Big problem actually

thin mesa
#

yeah can't new a MonoBehaviour

fresh salmon
#

new shouldn't be used with MonoBehaviour

keen cloud
#

so what do i do lol

#

take out monobehaviour?

#

ive never gotten to this point yet

#

idek what monobehaviour even means tbh

#

apologies

thin mesa
#

if you intend for it to be a component on a gameobject it needs to be a MonoBehaviour.
You have to reference an instance of the class which means you have to pass an instance to the static method you are calling

fresh salmon
#

Removing MonoBehaviour will prevent any Unity message like Start to be executed on the code

keen cloud
#

@sly grove im new with unity lol

fresh salmon
#

And, if you don't need that script to be attached to a GameObject indeed, then remove MonoBehavoiur

#

Epic ping fail

keen cloud
#

so

#

theres no way around this

fresh salmon
#

You'll have to make the method non-static

#

Other scripts will need an instance of that script to call the formerly static method

keen cloud
#

wait

#

im trying to call that on button press from another script

# keen cloud ?

you're now attempting to call it like a static method. An instance of the object would be a reference to a currently active SubmitCode in the scene. Which you would use one of the several ways to reference game objects in that video i linked to get a reference to

abstract pivot
# 
    IEnumerator Voice()
    {
        AudioSource audio = audioSource.GetComponent<AudioSource>();

        audio.clip = voiceClips[index];
        audio.Play();
        yield return new WaitForSeconds(audioSource.clip.length);

        while(audio.isPlaying) //The problem.
        {
            if(!currentlyOnDialogue)
            {
                audio.Stop();
            }
        }
    }

I am developing a dialogue system the problem is that when the players close the dialogue window before the end of the voice line, the voice line continues to play. So I created a simple while loop to prevent this, but this loop strangely affects the performance of my game. I need help...

sly grove
#

Otherwise you're not going to finish the frame until the audio stops playing

thin mesa
# keen cloud ?

here's what you need to do:

  1. get a reference to an instance of SubmitCode using one of the referencing methods I demonstrated in the video
  2. call your method on that instance like so:
    myReferenceToSubmitCode.SetValuesFromDB();
abstract pivot
sly grove
#

Otherwise you're going to keep looping within the same frame, never allowing the frame to finish until the audio is done
