Maybe not a separate class, just the same, partial, with broader access modifiers. For example, if you don't want the end user to be able to access the static Instance, make it internal so it's not available outside of its assembly

#

Keep the proxies public so the user can access them

urban warren
#

My thinking for using a separate class would be to remove the MonoBehaviour static methods like Destory() and Instantiate(..) etc.

#

Just so it is cleaner and would only have the things that are actually relevant

fresh salmon
#

It really depends on the use case yeah, if you don't want the end user to be able to access .gameObject and other members derived from MonoBehaviour, then sure make a whole new class

urban warren
#

Alright, cool I just wanted to make sure I wasn't doing something that would be considered 'ugly' or unintuitive code. Thanks! 😄

Hello,
Im Building a multiplayer game and there is something that Is not clear about Netcode.
I have the client totally separated from the server, so the server will do all the Logic and then the result Will be propagated to all the clients.

The question is, how can i call a server method from the client if they are totally separated?
Inside the documentation they explain the approach of client to client host, but not the client to dedicated server..

#

Should i declare the same method on the client without putting the Logic inside?

For 32 768 iterate 100k items for 3800ms it's correct ?

#

other thing more efficient than parralel ?

@alpine nebula you could try to state your issue using full sentences. I dont get any sense of what you just said…

why waste time say lot word when few word do trick

Anyone know how to put animations into a unity character?

formal lichen
#

probably have better luck in animation, unless you're trying some new homegrown procedural animations

#

Anyone know of a way to create and reference functions or events in editor. I'm thinking something like the same functionality as a scriptable object. The idea being for my dialog, each individual button can be labeled and then call something dynamically.

sly grove
severe grove
#

or even just invoke an event.

sly grove
severe grove
#

Thank you very much.

#

well, not quite what I am asking. I am using the same system for navigation. I use a struct to pair a label to a command. the question is how to predefine the command in a way that is easy for level design. for instance, I want one button to be labeled north and make an event call that moves the player north. another button I want to have the player explore the space and trigger something else. What data structure could be used to predefine the events for referencing?

asdf.PNG
#

I've thought about setting up a enum and referencing a static class but the issue is what if I need to send data with the event?

sly grove
#

Then you can hook your UnityEvent up to call the function

#

Otherwise you can simply create your own system in code e.g. with Dictionary<string, Action> or Dictionary<MyEnum, MyDelegateType>

severe grove
#

alrighty. I'll take a closer look. thanks.

pure dock
#

that's basically a Facade pattern. it works well for an singleton proxy . . .

Fun question for ya. I have a large number of classes that derive from others. I would love, for organization's sake, to put them all in one script, like so:

    public abstract class TypeNode<T> : ScriptableObject
{
    public class GameObjectNode : TypeNode<GameObject> { }
    public class AudioSourceNode : TypeNode<AudioSource> { }
    public class AudioClipNode : TypeNode<AudioClip> { }
...
}

but doing this means that when I try to save my scene, I get this error and some of the data does not save:
No script asset for AudioClipNode. Check that the definition is in a file of the same name.
Is there a workaround for this? Or do I really have to have each and every class in its own file?

hybrid ravine
#

You should have all your classes in separate files, it is usually best practice. But you don't have to, you can leave them in the namespace instead of putting them inside an abstract class

#

I think that unity does get confused if you put them in the same script as a scriptable object tho, so you should make a new .cs and put them all in there

urban warren
#

Every Monobehaviour and ScriptableObject must have its own file

quick curiousity question

#

with a c# setter

#

why is the common pattern to use a backing store

#

instead of making use of the this keyword in some way?

hybrid ravine
#

what do you mean by backing store? having a private variable for the value?

whole badge
# 
class Person
{
    private string _name;  // the name field
    public string Name    // the Name property
    {
        get => _name;
        set => _name = value;
    }
}```
#

the example provided by .net

hybrid ravine
#

you basically have 2 types of get set, the empty ones like
public Field {get; set;}

#

and the other like your example

#

the empty one stores the value, while the other is actually just Methods

whole badge
# 
public float height {
            get { return Mathf.Min(corners); }
            set { height = value; }
        }```
#

will this set work?

austere jewel
#

That's an infinite loop

hybrid ravine
#

not to my knowledge, which is quite experienced with c#

whole badge
#

ohh you're right because it invokes it again

#

oh then that's ,, huh.

hybrid ravine
#

as I said, when you fill in the get and sets, it becomes only 2 methods disguised as a property

whole badge
#

yeah i feel you

hybrid ravine
#

you don't actually have a variable in that case

whole badge
#

oh

hybrid ravine
#

you just have 2 methods

austere jewel
whole badge
#

i'll just do it this way then

# 
public float height {
            get { return Mathf.Min(corners); }
        }
        public float SetHeight() {
  // stuff
        }```
hybrid ravine
#

well, are you storing the height?

austere jewel
# 
public float height {
  get { return Mathf.Min(corners); }
  set { /* stuff */ }
}```
as long as "stuff" isn't setting `height`
whole badge
#

height is just a function of some other variables

#

it might be nice to think of it as a property but it's not strictly necessary

# 
[System.Serializable]
    public class TerrainCell {
        public float[] cornersRelative = new float[4] { 0, 0, 0, 0 };
        public float[] corners = new float[4] { 0, 0, 0, 0 }; //corners above 0
        public float height {
            get { return Mathf.Min(corners); }
        }
        public void SetHeight() {
            SetCorners(new float[4] { cornersRelative[0] + height, cornersRelative[1] + height, cornersRelative[2] + height, cornersRelative[3] + height });
        }
        public void SetCorners(float[] newCorners) {
            corners = newCorners;
            for (int i = 0; i < 4; i++) {
                cornersRelative[i] = corners[i] - height;
            }
        }
    }```
#

just in case you're curious

#

should make cornersRelative read-only too

hybrid ravine

@hybrid ravine Not sure if you're still here, but that error is back and again it's not saving data. I really hope I don't have to have tons of individual scripts to define each derived ScriptableObject.

Hey guys, so I have a custom editor, and Normally I use SerializedProperty/SerializedObject, which means I dont need to set anything dirty. But this time my field is a custom class so I am accessing it directly. Though the logic I run takes place, the inspector window does not always register the changes. how do I go about reflecting those changes in the inspector? I tried:

EditorUtility.SetDirty(this);
Repaint();

flint sage
#

You can use serializedproperty for custom classes?

#

And can you share some code?

fervent parcel
#

ok so I have a list inside a class, how do I access it from custom editor as a SerializedObject

flint sage
#

SO.FindProperty("list").GetArrayElementAtIndex(i)

fervent parcel
#

one sec, let me try it

fervent parcel
#

writing this in the inspector as a serialized object feels like a pain

rider64_PmTvNAOviQ.png
#

and yes, I know I could loop it, but I mean a single line

pseudo crown
#

You can put whatever you repeat more than once in a helper function. Doesn't usually matter if its SerializedObject or plain class properties.

fervent parcel
#

Also, is FindProperty(string) more expensive?

pseudo crown
#

yes it is, if you're doing it hundreds of times, you will likely have some Inspector lag (e.g. if you have an array with 100 tiles and do FindProperty multiples times for each entry).

fervent parcel
#

Another reason why I should do it directly from the target script

pseudo crown
#

but it gives you all of the implementation goodies. Without it, you would have to handle Undo and prefab overrides and potentially some smaller pitfalls like change checking and repainting.

fervent parcel
#

Is there a comprehensive guide on all this?

pseudo crown
#

If you're in an Editor class you should simply have to call Repaint() to make the Inspector redraw.

fervent parcel
#

I mean, I been doing editor scripting for 2 years now and I still dont fully understand it

#

no, the class is on the target script

pseudo crown
pseudo crown
# fervent parcel no, the class is on the target script

If that means you're trying to repaint the editor of a different instance, its more difficult. You could try repainting the window directly, but its difficult to get a reference to it. E.g. EditorWindow.focusedWindow.Repaint();

fervent parcel
pseudo crown
#

As far as I know however, if you do new SerializedObject(someOtherClassInstance).FindProperty("myProp")... bla bla and Apply, it will repaint the inspector for you. So before you find that performance is the real bottleneck here, maybe go that route.

fervent parcel
#

Alright, cheers mate, I will give it a shot, my pc is 6 years old so if it works on it, it should be fine

flint sage
#

If you're doing GUI.TextField(target.text) then that should always update if you repaint

#

If you're using serializedobjects for one bit and direct object access for other bits

#

Then you probably have to call Update on your SO

#

But htat overrides all changes you've made to serializedproperties of that SO instance

I'm not sure if this should be here or in #📲┃ui-ux but i was trying to build a Procedural Skill tree system that would list skills like this automatically. I'll just internally set all the skills that are a part of that skill tree and it would expand accordingly, my issue right here wasn't with the code itself but more with the skill tree's showing up in the UI properly.

So let's put it that i have 2 or 3 characters for now and i want them to be able to have different skill trees. The only way i seem to be able to setup the position of the icons is by either using a grid and forcing it to bee a bit too geometrical for what i'm going for or making the UI individually for each character (which defeats the whole purpose of it being procedural).

Does anyone know if there is a solution for me to adapt it via code so things will try to adapt and connect themselves properly and how viable they are? I could also code a whole method to just calculate the best positions for each square in a empty object and then calculate a path that can be drawn to it but do you think its worth the effort or should i just opt for doing it manually?

warm glen
# novel plinth that's not procedural

the point is for it to be :/ tho i guess i could also be using the wrong word, english isn't my first language. All i want is the UI to generate depending on the skill tree that was created with the different skills.

Let's say i have skill A B C D E F and G

For char 1 i can go

A--B--C
 |-D--E

But char 2 can go

A--C
 |-D--F--G
    |-E
#

i know it looks a bit of a mess in that example, but i'm not able to draw an example right now

#

but as i said i want the UI for that to be done through code, not manually

Does anyone have experience with with Blend Shapes, specifically with SkinnedMeshRender.sharedMesh. I'm trying to determine if it's possible to remove a single blend frame. I have a collection of vertex data to map into the shared mesh, and Unity seems to cache this somehow, but I need to retain a whole prebaked collection of blends, so I'm not sure if it's possible either to copy that data out and create a new massive collection to assign, or clear Unity's cache, or another solution. The core issue is that I can't replace a blend with the same name.

Solved: It was actually quite easy to just iterate through all the blend frame data and create a temporary list class to store all the original blend data inside, and when you are done you can clear all blends on source that were modified and replace.

Hey frens 🌞 anyone here has experience with GoogleCloudPlatform ? i'm trying to get to download my SSL cert.pfx or cert.json so I can put it in the VM and have my webGL client connect to it. But can't find anywhere on GCP where i can download either of those : /

# warm glen I'm not sure if this should be here or in <#502171135350407168> but i was trying...

I think you can do this in Unity’s UI using a horizontal layout group for the levels and a vertical layout group for the nodes in each level. The vertical layout group would be aligned to the center. The one thing I’m not completely certain about is how to do the lines…. though you can probably do it as a series of images that you scale algorithmically and parent to the overall panel itself rather than the layout groups, with positions set based on their connected nodes.

@tough tulip Thanks, I ended up just creating a temporary reference to all it's blends at runtime by iterating through the frames, and restoring the modified mesh back to it's original when completed.

Hi folks. I'm currently creating a space exploration game and the planets and character are both rigidbodies. This is an issue because the mesh colliders of the terrain can't be attached to a rigidbody. Right now I'm just using LerpUnclamped to move the colliders to the planet's position and rotation. My primary issue is that the player controller doesn't move with the terrain, even without drag, and I tried using physics materials. I am not sure how I would transition a scene from a dynamic frame of reference to one fixed to a body moving through space

I want to get into more advanced physics and graphics coding. I decided to take a crack at my own fluid simulation. I decided to create spheres and code their own physics solver so they have hydrodynamic behavior. My next challenge is to have the camera render them as a liquid. To do this, I was thinking of injecting the data into a graphics buffer and use a shader to determine their visual properties like, if they are fused together based on their proximity to one another, their volume (or thickness) based on how many are “fused” together, and other factors. I am going to use HDRP, and wanted to know if this is possible, and if this is a reasonably proper approach. If so, I never used a GBuffer and I have Shader Graph experience, but I don’t know yet how to have shader pull data from buffer. So this will be new territory for me and I wanted to get some guidance on where to start, maybe have some example code to look at?

Hello, I am having an issue with Assembly Definitions. scripts inside my Assembly Definition should be able to see namespaces inside Assembly-CSharp, but cannot. It can see things like UnityEngine, OdinInspector, etc., but cannot see my namespaces.

Hello guys, i am trying to stream a real camera video into unity and i want the lowest latency possible. Data comes from camera in JPEG over UDP. I receive them in unity and use LoadImage to load them into the scene. Problem is: loadimage is really slow. It adds 60ms latency to the camera’s 90ms latency. 150ms in total. If I stream over h264 (not to unity) I achieve 55ms camera latency

#

Is there a way to reduce the unity processing latency?

Optimistic, but ... has anyone managed to get a callback for 'AssetDatabase-will-refresh'? Unity's compilation crashes/throws an unhandled exception when multiple DLL's exist in the project with same name, which makes it a nightmare to import external DLL's, so I'm trying to create a script that will auto-rename them on import (script works 100%, it's just Unity that gives up, and then doesn't allow any more code to run)

Folks, what's the best way to handle dev/prod environments?
Do you guys exclusively create dev builds and use #IF_DEVELOPMENT defines to handle dev env only code?

#

Any other practices I can follow?

sly grove
hallow elk
#

How? it is not available in the reference list.

sly grove
#

Do you have one?

#

Did you make one?

#

It's like @ivory salmon said you need everything to be covered by an asmdef if you're using them

hallow elk
#

Assembly-CSharp is not in the reference list.

sly grove
#

Because you didn't create it

hallow elk
#

I didn't create what?

sly grove
#

You need to put an Assembly Definition file (asmdef) in your main scripts folder to define an assembly for it

#

then you can reference that assembly from other asmdefs

hallow elk
#

My assembly having the issue needs to be able to reference scripts all over the project, so that won't really work

sly grove
#

You're approaching things wrong then

flint sage
#

Assembly-csharp references your asmdef, you can't reference it the other way around

#

Since circular references are not a thing

sly grove
#

Let's back up - can you explain what you're trying to accomplish?

ivory salmon
#

every folder that has classes will need an asmdef (or its parent ... grandparent ... etc will need one)

#

its all or nothing: use asmdefs, or dont use them

hallow elk
#

Ultimately I don't think I'm going to use them in this case.

ivory salmon
#

the presence of asmdefs changes the way Unity builds your project (bit of a simplfiication, but broadly true)

hallow elk
#

It's very weird, though, because this worked up until recently, and stopped working for different members of my team at the same time, who were all working on different branches

ivory salmon
#

ALSO: when changing asmdef setup, and there were ANY errors ... there are bugs in UnityEditor, such that you literally have to close the editor and restart it in order to see the actual error messages

flint sage
#

Nah it didn't, asmdefs can't really reference assembly-csharp

I'm trying to implement an A* algorithm. I think I have all of the necessary information, but I'm kind of stuck getting further. Can someone take a look at my code at tell me where I should go from here?

#

Afternoon, Praetor

sly grove
ocean raptor
sly grove
#

Otherwise you're dealing with floating point precision errors in. your pathfinding logic which is nasty

ocean raptor
#

That helps

sly grove
#

Although wait is this a hex grid?

ocean raptor
#

It is

sly grove
#

Ok so you'll need to adopt a hex coordinate system

ocean raptor
#

I probably should have tried my first implementation on a square grid, but as I understand it, A* is agnostic of grid type

sly grove
sly grove
#

as long as your GetNeighbors works consistently and properly then the grid type doesn't matter

ocean raptor
#

I was recommended that site by a number of people on GDL, but to be honest, a lot of it is over my head. It's well written, I'm just slow.

sly grove
#

Yeah it has a ton of useful info for hex grids

ocean raptor
#

Does it have anything regarding converting Vector2 coordinates to hex axial coordinates?

#

Although I think I have a line that can do that

Vector2 newV2 = new Vector2(i * 1.5f, (j * 1.75f) + (i * 0.875f));
sly grove
#

that's hex -> world and world -> hex

#

it depends on which coordinate system you're using

#

there's sample code for each type

ocean raptor
#

When I'm calculating my G, H, and F, should I be using a raw distance or the number of tiles?

sly grove
#

G H and F?

#

You mean for A*?

ocean raptor
#

Yes

sly grove
#

It depends on how your movement works

#

if your character can only move on tiles

#

and the distance is based on the number of tiles

#

then you use tile distance

#

But there's potentially a difference between your heuristic function in A* and the actual distance function. The heuristic is just used to determine which directions to check first

ocean raptor
#

This isn't meant to be the actual map a player moves around on

#

Each tile represents a star system, and the player moves from system to system.

#

But they don't directly move on the hexmap, if that makes sense

sly grove
#

So what's the purpose of the hexmap

ocean raptor
#

To display the position of star systems in relation to each other.

#

And to help plot a route from one system to another.

sly grove
#

Is it like, the player can only jump a certain maximum distance, so they have to find a path of systems which are close enough to each other to leapfrog across since they can't jump directly from origin to destination?

ocean raptor
#

Have you ever played EVE Online or Elite Dangerous?

sly grove
#

Yes

ocean raptor
#

Which one?

sly grove
#

Both. A lot more Eve than Elite

ocean raptor
#

my condolences from a fellow bittervet

sly grove
#

lol

ocean raptor
#

You know how you can open the star map and plot a route from Jita to like.. Amarr or something?

sly grove
#

Sure

#

And then it's a path based on the jump distance of your ship IIRC? But it's been quite a long time

#

Did ships have jump distances?

ocean raptor
#

Subcaps don't worry about that, it's just capitals that have that, and they just have point-to-point jumping

#

Subcaps have to go through the gate network

#

That's where the routing came in

#

But you weren't hitting a button on the map that moved you from one point to the next, you have to fly to the gate, jump to the next system, fly to the next gate, repeat until you've arrived.

#

Anyway, this is partially for routing, to let player plot a route

#

But also for validation, to make sure there aren't orphan systems or systems you can't get to because it or its group doesn't have any neighbors.

#

Since each tile has a 1:X chance of just not existing, it can create tiles or tile groups that aren't connected to the rest of the map

#

So the pathfinding is intended to validate each system and make sure it has a path back to 0,0

ocean raptor
#

Damn, he's got a hell of a lot more on there than hex grids..

#

if I add a function to a buttons onclick, do I need to worry about removing on destroy?button.onClick.AddListener(OnClick);

Does anyone know if Unity's raycast is non-deterministic? (note the camera transform is also constant)

            Ray mouseRay = cameraComp.ScreenPointToRay(Input.mousePosition);
            new Plane(Vector3.up, Vector3.zero).Raycast(mouseRay, out distance);
            Debug.Log("Camera Comp: " + cameraComp.GetHashCode() + ": INPUT<" + Input.mousePosition + "> + DIST<" + distance + ">");

Output:

Camera Comp: -827432: INPUT<(481.00, 495.00, 0.00)> + DIST<58.30573>

So I decided to take the reflection route for my classes, @hybrid ravine. Now how to serialize and show the attributes I’m missing in the inspector?

#

I got the fields with a field array. Now’s just to set them onto the object with the for loop.

hybrid ravine
torn geode
#

The bizarre thing is that it’s being returned as the subclass. It’s only just missing the rest of the variables in the inspector, like an enum that states which stats are being affected.

hybrid ravine
#

Oh right, so your values are not being serialized?

torn geode
#

Yep!

hybrid ravine
#

okay, first make sure your custom editor is not re initializing those values or anything like that

#

Do I need a custom editor? If so, which sources can you point me towards?

You can access that setting in the console window's dropdown

#

the setting affects the one in the Player settings and therefore also changes what happens when you build

#

so be aware of that

Why does my node not start with an initial value I set in code when I add elements to the list with the plus button?```[System.Serializable]
public class DialogNode
{
public string label;
[HideInInspector] public string id;
[TextArea(10, 10)] public string content;
public List<string> children;
public bool isRoot;
public List<Flag> requiredFlags = new List<Flag>();

public DialogNode()
{
    label = "New Node";
}

}```

long ivy
#

because label is immediately overwritten by the serializer right after your constructor runs

severe grove
#

how do I make it not do that?

long ivy
#

Why aren't you using a field initializer instead?

severe grove
#

This is all sitting inside a scriptable object of Dialog.

#

DialogNode is a class I am using to store data.

#

If I don't serialize the whole class, It wont work as a member of a list in editor.

# 
public class SO_Dialog : ScriptableObject
{
    public List<DialogNode> nodes = new List<DialogNode>();
}

[System.Serializable]
public class DialogNode
{
    public string label;
    [HideInInspector] public string id;
    [TextArea(10, 10)] public string content;
    public List<string> children = new List<string>();
    public bool isRoot;
    public List<Flag> requiredFlags = new List<Flag>();

    public DialogNode()
    {
        label = "New Node";
    }
}```

Unfortunately. That also returns nothing.

#

reset your script

severe grove
#

I created a new scriptable object and no change. is there a more direct way to reset?

hybrid ravine
#

in your component thingy

#

in the inspector, that is

severe grove
#

good to know.

#

but yea, still returns a blank string

hybrid ravine
#

Well, you must've done something else or Unity is just being weird

severe grove
#

hybrid ravine
#

I looked for a default value attribute, but I don't think there is one

the other thing from before always worked for me

Hey guys I need help, I'm making a Mobile/Pc Game called "Ultimate Hide And Seek" I need to make roles such as Hider, Seeker and Ninja, Hider is well a hider they can only hide, Same for the Seeker but he can not hide only find And now the Ninja Can hide, Go invisible for 5 seconds and stun the Seeker. I also need these to work with online multiplayer with cross platform

so you need to hire a developer? idk if we can help you here

#

im trying to make a status effect system and i had it as an abstract class, but i cant find any way to reference the children scripts. is there a way to do this or should i just make one big all encompassing scriptableobject script for it?

coral blade
#

@raven jewel

if(theObject is ChildClassType)
{
    ((ChildClassType)theObject).CallCommand();
}

but I haven't used abstract classes so I am not sure how that plays in.
that is how I check for an objects type when there is multiple child types

tough tulip
#

or you can use [NonSerialized] attribute for the field which you dont want Unity to override the value. But you cant see the value in inspector anymore

raven jewel
#

@coral blade i should specify that i have potion items that are scriptable objects and they cant hold abstract classes since abstract classes arent serializable. im kind of lost on how to make the potion grab the right status effect

tough tulip
raven jewel
#

that is kind of the solution i was thinking of since my method wasnt working. thank you

raven jewel
#

actually would the abstract monobehaviour be necessary? i could just the code on the scriptable object itself and just take in the different variables. since scriptableobjects cant store abstracts anyway

hey, i'm looking for some advice to optimize this cell operation as much as possible

#

it adjusts the tiles proportionally in a circle, as you can see

#

now

#

the tiles are grid based

#

but the position of the operation itself is not grid based

#

the affected area can be at non-integer positions and sizes

#

and lastly, the grid is 5x1x5 per unit

# 
public void RaiseLowerTerrainBrush(float x, float y, int amount, float diameter) {
        Vector2 center = new Vector2(x, y);
        Vector2 centerTile = WorldToGridLocation(center);
        float halfDiameter = diameter / 2;

        Vector2 corner1Tile = WorldToGridLocation(new Vector2(x - halfDiameter, y - halfDiameter)) - Vector2.one;
        Vector2 corner2Tile = WorldToGridLocation(new Vector2(x + halfDiameter, y + halfDiameter)) + Vector2.one;
        Vector2 size = corner2Tile - corner1Tile;
        
        int startx = (int)corner1Tile.x;
        int starty = (int)corner1Tile.y;
        
        int tilex, tiley;
        for (int i = 0; i < size.x; i++) {
            tilex = startx + i;
            for (int j = 0; j < size.y; j++) {
                tiley = starty + j;
                Vector2 worldPosition = GridToWorldLocation(tilex, tiley) + blockOffsetToMiddle;
                float tileAmount = Mathf.Abs(Mathf.Clamp01(Vector2.Distance(worldPosition, center) / halfDiameter) -1);
                RaiseLowerTerrainCellCorners(tilex, tiley, amount * tileAmount);
            }
        }
        for (int i = 0; i < diameter; i++) {
            tilex = startx + i;
            for (int j = 0; j < diameter; j++) {
                tiley = starty + j;
                MatchTerrainCellCorners(tilex, tiley);
            }
        }
    }```
#

so there's my code

#

the first part is defining the size of the affected area (which is initially in world units)

#

and then figuring out which tiles in the grid to operate on, in a region

#

and then doing the actual adjustment on each of those tiles

#

is there a better way?

Hi all, I'm working on an event system to process cutscenes in 2d. In this system an NPC will have a List of Events which will be processed FIFO when a trigger is fired.
For the system to work I need to be able to create and modify events in the editor, similar to how you can input a string. I thought I could do it with Polymorphism & Serialization, but this only gets me the result depicted in the screenshot NPC just has a List<SSSEvent>.
I've read some threads and watched a video on the subject, but I can't really find an example of what I want to do. Is it possible? What can I do to make Events from the editor?

Event examples & code can be found here: https://hatebin.com/fvzdjkzkmi

After a bit more research I've settled on storing events as assets. It's not the cleanest option but it works well both from a design and development perspective.

How can i hide dropdown list by script i found in documentation theres function Hide in class Dropdown by dropdown's that i created via editor dont have that class

shadow seal
#

UnityEngine.UI Dropdowns?

paper nimbus
#

yeah

#

i Created obj dropdown fromm UI option in editor but that doesnt have class like that

shadow seal
#

You have referenced it in script as a UnityEngine.UI.Dropdown though?

#

Because that seems to have a Hide and Show method

paper nimbus
#

I try to do that but dropdown that i created by editor dotn have class like that

unknown.png
# 
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class DropdownManager : MonoBehaviour
{
    public Dropdown dropdown;

    public void HideList()
    {
        dropdown.Hide();
    }
}
shadow seal
#

None of those are Dropdown components

paper nimbus
#

yeah

#

Thats what i say it does not have Dropdown script

shadow seal
#

Dropdown is a component you can add to an object, and you can have it build you one if you create it through the hierarchy menu thing

#

But none of those are Dropdown components, so ofc they won't fit into the field

paper nimbus
#

I builded it by hierarchy menu but it doesnt have it by default it's normal? to i have put it by myself?

#

I know they dont gona fit it but i talk about its normal to Dropdown fromm editor menu hierarchy doesnt have Dropdown script

shadow seal
#

I think you've deleted something

paper nimbus
#

Nope

#

Even tried make new one

shadow seal
#

Well I just made one, and there's the component

unknown.png
#

Albeit a TMP one

paper nimbus
#

😮

#

What version u use?

shadow seal
#

2021.1.22f1

paper nimbus
#

😐 2019 here so maybe thats a problem

shadow seal
#

But I highly doubt it's a feature of my version, I've used them before

#

I don't see there being any difference in 2019

paper nimbus
#

Damn

#

Maybe ill try to reinstall

shadow seal
#

What's the exact version you're using?

paper nimbus
#

2019.3.13f1

shadow seal
#

Idk then, I can use Dropdowns and they are constructed correctly in 2021.1

#

I have used them in 2020.3 as well

tough tulip
# paper nimbus Thats what i say it does not have Dropdown script

Right click any gameobject in hierarchy, click on UI/Dropdown
I've used them in 2018 and they indeed work.
If you manually add a dropdown component, you need to properly configure it. The context menu does it automatically for you.
And when dropping reference, use the new gameobject that was created under the gameobject you selected

Hey, is there any way to send UnityWebRequest GET in OnApplicationPause event? It looks like my coroutine with request is not sended if pause = true. Probably because main thread is frozen while the game is suspended.

regal olive
#

I'm not even sure what the correct term for this is, but how do people go about solving the common issue where players can grab objects while standing on them, and then use it to essentially fly?

#

Because the object is constantly trying to push itself up to the held position, while the player is standing on top of it.

#

If anyone gets what I mean

sly grove
#

make its Rigidbody kinematic etc.

hushed fable
#

Depends a bit on the mechanic, sometimes the objects are held somewhat far away from you or the objects are big, so you still want to treat them as physics objects

regal olive
#

In my case I do

#

Unless I am remembering wrong, don't kinematic rigidbodies ignore colliders on other stuff?

#

so you could just clip the object through the wall which would be a problem

sly grove
#

kinematic bodies are unstoppable forces that aren't affected by forces or depenetration, yes

regal olive
#

Yea that wouldn't work in my case because I want my held objects to be able to physically interact with other physics objects

#

If I could somehow make it selectively kinematic for the player that would be nice

#

but that doesnt really make sense I think

sly grove
regal olive
#

I dont see how that would be possible

#

I was thinking about that, my next concern would be players clipping into objects after they release them

sly grove
regal olive
#

Like if you pick up a table and can just put yourself in the center of it, I can see a lot of potential issues

sly grove
regal olive
#

What would happen in that scenario if I were to re-add collision while being directly inside of a large object?

hushed fable
#

Maybe you could Rigidbody.SweepTest the dragging movement and skip any movement that would result the object colliding with the dragging entity

regal olive
#

I'm trying to think of a game that has held physics objects that don't have this issue, I might go in and just experiment

#

maybe it will give me an idea of how they did it

#

Amnesia I think has it?

#

oh LOL

#

nevermind

#

amnesia has that exact problem

sly grove
#

hah that's funny

#

Contacts Modification API maybe?

regal olive
#

I don't know what the proper term for that is but

sly grove
#

So that the grabbed object is affected by the depenetration impulses but not the player

hushed fable
#

Granted it looks like in this case it's purely due to jumping logic

regal olive
#

What about logic to just check if the player is standing on top of something, and then working around that?

#

I just don't know how you can properly classify when a player is on something, it might depend on the object

hushed fable
#

Don't allow jumping on props that have recently been affected by dragging? 😄

regal olive
#

Well in my project you can't even jump

#

but you could take a cube, and drag it on the ground, walk on top of it, and boom

#

were flyin

#

It's because there's a resting position every held object tries to interpolate to

#

so perhaps if I can detect if a player is on object, just dont try to go to that resting position

sly grove
#

You can use the contact modification api to make that collisi1on not apply forces to the player, pretty sure. Or at least not upwards forces?

regal olive
#

Wait really?

#

I've never heard of this before

sly grove
hushed fable
sly grove
#

Does it require 2022 at this point?

#

That'd be sad

regal olive
#

I'm on Unity 2021.1.20f1

hushed fable
regal olive
#

Is it that ContactModifyEvent at the bottom?

#

Damn there's not too much on this

#

oh wait that post had a writeup on google docs

regal olive
#

Yea the easier solution was to just to a raycast from the player's feet down, if it hits the gameobject you are holding you're technically on top of that

#

after that it's just about altering the physics or how the object moves to its resting position

Hey guys, I'm having a very weird problem with c# and with no answers online,

I have a class, here it is:

 public class Slot
    {
        public Button button;
        public ImageGroup group;
        public GameObject Object;
        public int Price;
        public bool InCart = false;

        public Slot(GameObject o, int p, Button b)
        {
            
            Price = p;
            Object = o;
            button = b;
            group = button.GetComponent<ImageGroup>();
        }
    }

When I create a list of it, and change one of the values, or add a value, everything stays the same apart from Object variable, it changes to the last things I changed anything in the list to, here's an example -

I have this code here:

  list[2].Object.GetComponent<item_Pickup>().ScriptItem = item3;
        Debug.Log(list[0].Object.GetComponent<item_Pickup>().ScriptItem.name + " check1");
        list[1].Object.GetComponent<item_Pickup>().ScriptItem = item2;
        Debug.Log(list[0].Object.GetComponent<item_Pickup>().ScriptItem.name + " check2");
        list[0].Object.GetComponent<item_Pickup>().ScriptItem = item1;
        Debug.Log(list[0].Object.GetComponent<item_Pickup>().ScriptItem.name + " check3");

And here's the console (In the image),

The selected comment is saying the names of the items, BlueRing being item1, GreenRing being item2 etc...

This is weird, never happened to me before and has no solution online. Any help is greatly apricated, thank you.

I_cant.PNG
sly grove
#

What are you expecting this code to print

regal olive
#

Yay it works perfectly

ripe mango
#

I expect it to write BlueRing each time.

#

But it changes every time I change something else

sly grove
#

how'd you initialize the array

ripe mango
#

var list = new List<Slot>();

sly grove
#

right and then... how'd you populate it

ripe mango
#

this is the weird part though, this is a shop menu, where I write if(i < 3) it generates items, but the rest are powerups, but only the items have the glitch, the powerups don't. And they are the same class

sly grove
#

Can you simplify it? It looks like these are the two places you add Slots:

list.Add(new Slot(GetItemObject(item), BasePrice, ItemSlots[i].button));```
```cs
list.Add(new Slot(powerUp.Object, BasePrice, ItemSlots[i].button));```
#

So my guess here is that
powerUp.Object
and/or GetItemObject(item) are always just returning the same GameObject

ripe mango
#

those are different items in the shop... the powerups and the items

ripe mango
# 
public GameObject GetItemObject(Items_Scriptable item)
    {
        //Debug.Log(item.name);

        GameObject obj = ItemPrefab_G;
        var i = obj.GetComponent<item_Pickup>();
        i.ScriptItem = item;
        i.is_Gravity = true;
        i.force = 0;
        return obj;

    }
#

it just creates a gameobject with those values and returns it...

sly grove
#

That's taking an existing prefab and returning it

ripe mango
#

it is, it's changing the Item_Pickup values

sly grove
#

sure but

ripe mango
#

i.ScriptItem = item;

#

item is passed

sly grove
#

every time you call GetItemObject you're literally returning the same GameObject

ripe mango
#

no

sly grove
# 
GameObject obj = ItemPrefab_G;
return obj;```
#

the stuff in between is almost immaterial

ripe mango
#

GameObject obj = ItemPrefab_G; var i = obj.GetComponent<item_Pickup>(); i.ScriptItem = item; i.is_Gravity = true; i.force = 0; return obj;

#

there is a script right

sly grove
#

yes

ripe mango
#

item_Pickup

#

item here

sly grove
#

I understand that

ripe mango
#

is a scriptable objecy

#

that holds all the info about an item.

#

and I set it to be an item that I get from the code

sly grove
#

In your loop you're doing this:

list.Add(new Slot(GetItemObject(item), BasePrice, ItemSlots[i].button));```
#

a new slot with the Object being the GameObject returned by GetItemObject(item)

ripe mango
#

right, and item is chosen randomly

sly grove
#

That sGameObject is always ItemPrefab_G

ripe mango
#

in here - Debug.Log(list[0].Object.GetComponent<item_Pickup>().ScriptItem.name + " check3"); the main debug, I am debugging the value I changed

sly grove
#

So all you're doing is taking ItemPrefab_G's Item_Pickup script, pointing it at a different item, and returning ItemPreab_G

ripe mango
#

yeah

sly grove
#

All of your slots are still pointing at ItemPrefab_G

#

so when you change ItemPrefab_G

#

all the slots see that change

ripe mango
#

but I create a copy of it

sly grove
#

No you don't

ripe mango
#

my god

#

I do not?

sly grove
#

Where are you creating a copy?

ripe mango
#

I messed that up? I never in my 3 years of preoggramming in unity ever created a copy

#

so how do I do that?

sly grove
#

The way to copy a GameObject is with Instantiate

ripe mango
#

right, But I don't wanna insatiate it

#

yeah, I'm dumb

sly grove
#

Well you know your problem now

#

you'll need to restructure something

ripe mango
#

thank you so much

#

I'm so dumb though

#

do you have an idea of how I can do this though?

#

idk, thank you though, a lot

#

I'll figure it out

sly grove
#

I'd just say that generally changing any data on a prefab is kind of an unusual and strange thing to do

ripe mango
#

I know, because of that I never considered that a problem...

#

I just need to change some parts of the system

Can anyone give me a bit of advice debugging my overlapcapsulse?

#

This is my situation, the capsule should cast forward, the yellow and red gizmo wirespheres indicate the start and endpoints
but instead it appears to cast downward and returns the debug.log name of the terrain the player stands upon
the radius is only 0.2f, so nowhere near large enough to hit the terrain if the cast were being performed properly (forward)
I feel like the method info is lying to me 😩

cobalt dome

yeah idk? i havent used overlapcapsulse but it looks like it should be working.

hexed meteor
#

yeah... seems like it's broken, although that's kind of hard to believe ...

austere jewel
#

point1 The center of the sphere at the end of the capsule.

cobalt dome
#

he just needs to add transform.position + dir * distance.

#

Cause direction * distance is getting the a vector in the right direction but it’s not in the position you want so the end position isn’t where you want it to be. You need it to start calculating for your transform.position

origin + ...

Other question. Can i feed that normalized time back into the animator component

I just want to be able to resume playing the same animation at the exact spot.

blending between animations could throw a wrench in it, but it sounds like you're using sprite animations that are not blended anyway, so probably a non-issue

#

I dont use layermask or other complex stuff so i think it should work. Ofc im saving the bools and parameters so there wont be any issue on that end.

gray pulsar
#

yeah... if you're mid-transition between two animations it probably would not playback the same way when you reload. You might be able to recreate the whole state of the animator, but... is it that important? Probably more effort than its worth imo.

whole badge
#

how do I replicate adding one of these in code?

#

so it can't be that

#

because the system in the inspector does

austere jewel
whole badge
#

oh

#

can you not add event handlers at runtime?

austere jewel
#

Not persistent ones.

whole badge
#

what does persistent mean in this case

austere jewel
#

AddListener can take arguments, just use a lamda

#

It means it's serialized in the inspector

whole badge
#

all right

#

that won't be necessary i think because my use case is the item gets instantiated at runtime and then has a listener added to it

#

ok so something like this?

# 
Toggle toggle = button.GetComponent<Toggle>();
            toggle.onValueChanged.AddListener(() => { ToggleActivityFolder(activityFolderKey); });```
austere jewel
#

yup

whole badge
#

it doesn't appear to be adding the listener

#

oh it is nvm

#

@austere jewel quick question

#

i read that the variable stored in a lambda is a reference

austere jewel
#

it becomes a closure, which is a complex thing to explain

whole badge
#

is this going to change because of iterating shenanigans?

austere jewel
#

No, though I'd watch out if you use a for loop, the index would need to be copied to a local variable before use

whole badge
#

ohhhh okay i wondered that

#

if i add a value to the call instead of a reference where does it get stored?

austere jewel
#

Research closures, I'm not going to explain them

whole badge
#

are dictionaries addressable by index?

#

oh hold on

#

so it'd be something like this potentially

#

if i understand correctly

#

because kvp is the iterator variable so i have to make a local one

#

it appears to work

Hi, I have a problem with Timeline.
I created a track, playable and clip custom script, the clip has a reference of gameobject in scene.
Until I make the build it works, then when building it loses the reference.
this are the scripts:

using System.Collections.Generic;

Hello everyone! I am working with Unity and jslib and having some issues calling the jslib functions from within c# functions. They only seem callable from within the Start() function. Is this normal behavior?

Anyone know resources (videos, books, papers, blogs) about how to apply functional programming (style) to game development, specifically in Unity?

drifting galleon
compact ingot
pseudo crown
#

Some people make points about how Reactive Programming is much better suited to mobile game dev. I have no experience with it, but I believe that's kind of a functional style working with streams of data etc.

compact ingot
drifting galleon
#

+1

compact ingot
#

react(ive) is nice in theory but also produces heaps of unreadable code

#

some people are satisfied with theoretical beauty that gets dirty immediately when encountering the actual world

#

i'd say in gamedev you have to mix and match a lot of paradigms to be successful.. from procedural, OOP, declarative, functional... there is room for all

#

but no one paradigm takes you all the way

drifting galleon
#

anyway, if you want to have some functional programming in unity, the easiest way is to write your code in F# and then compile it into a dll.

drifting galleon
compact ingot
#

you can also start with expressions and linq in your load/init code. thats pretty functional already

drifting galleon
#

exactly

compact ingot
#

F# has pretty different API idioms than C#, so it might be very awkward to make them work nicely together

drifting galleon
#

well ~~~about

compact ingot
#

i just mean its not as nice as it could be as if the api were to stay in an F# environment

drifting galleon
#

you could also extend the unity roslyn to support F# compilation natively and then inject your custom roslyn into unity. then you'd have pretty much native support

pseudo crown
# compact ingot but no one paradigm takes you all the way

Where I'm coming from: studied Game Design and Programming at university, worked as software engineer for a year, three more years as a Game Dev, did some fun learning exercises like the Harvard computer science course, read those "classic" books like Code Complete, Programing Pearls, Uncle Bob Series, etc, but the more I learn about game programming, the more it feels like a big mess where nobody knows what they are doing and everything gets out of hand quickly. So now I'm just trying to broaden my horizon a little. Ideally with something scientific, since most of Unity is already only anecdotal and I feel like we need more reliable sources.

#

Or, if there was even a single example of a functional style game, that would be something to compare against. But so far, it seems like its only being used in the enterprise cloud/backend environment.

drifting galleon
#

yeah. because that makes sense

compact ingot
drifting galleon
#

pls

compact ingot
#

or rather they come with a big asterisk

drifting galleon
#

yeah which is terrible imo

#

but if you don't change it yourself, well, it'll always be like that

compact ingot
#

but what are you gonna do... we can't use stuff here that is aimed at fixing OOP in enterprise environments

drifting galleon
#

exactly

compact ingot
#

there are plenty of other patterns, but those aren't as "neat" as uncle bob's apostles makes it seem

#

game code is such a complex problem there can never be a clean solution that makes it all beautiful on the inside

pseudo crown
#

I found it pretty interesting to read about how NASA and e.g. Airbus are collecting actual scientific data on how their software projects are working for them. They even do stuff like implement the same software with two different teams in two technologies or processes and try to evaluate which one suits what. I can't find any such thing about game dev. AAA only crunch out their titles, but don't seem to reflect or share much other than the occasional GDC talk (I don't want to downplay these sometimes immensely valuable talks, but in the broad picture there's not much out there).

compact ingot
#

all you can have is pretty islands

compact ingot
drifting galleon
compact ingot
#

still way simpler than your average game, but considerably less buggy

drifting galleon
#

i guess that's true

compact ingot
#

also nasa doesn't have to make the rocket fly in a pretty and entertaining way, it just has to not explode and reach the target.

pseudo crown
#

Something that got me starting to think about other than the typical Unity style was this: https://tech.innogames.com/reactive-programming-unity-introduction/

They are a pretty successful company here in Germany, so at least I wouldn't say it's complete rubbish, also not about making things beautiful since they need to earn their money. But again, not really making an argument for purely functional styles or anything, their blog also only dips a toe into async data streams.

compact ingot
#

mad respect for people who can throw a car to mars and drive around with it for 10 years without it crashing

#

but it is proabably only difficult because there are no yt videos who tell you exactly how to do it

#

lol

drifting galleon
compact ingot
#

anything event-based is difficult to debug... i'd avoid that in games if there is no obvious way to validate its structure

#

there is a beauty in procedural code.. .you can just step through it and figure out what is going on

pseudo crown
#

That's my experience as well, but intellectually, I kind of understand how state and timing is much more error-prone in theory.

compact ingot
#

yes, event/concurrent stuff needs some big design patterns, even architecture to not explode

#

thats why functional is nice in that space... its a very strong pattern to deal with concurrency

drifting galleon
#

the best 'functional' approach is probably ecs and dots. well...it's a bit different, but purely functional if you dig deeper into it. although you write it differently

compact ingot
#

its a purely procedural approach to evaluating functions

#

but it has nothing like the safety that FP offers

drifting galleon
compact ingot
#

everything in dots just yields into shared state, no such thing in FP

drifting galleon
#

it always operates on the values. there's no not operating

compact ingot
#

thats only part of what FP is

#

FP primarily has no side-effects

#

and dots has massive amounts of side-effects

#

it has only side effects

drifting galleon
#

you're operating on the input only. there is no state

compact ingot
#

just because your "function" runs on a struct doesnt make it "functional"

drifting galleon
#

but there's no state

#

to have side effects on

compact ingot
#

that makes no sense

drifting galleon
#

in what way

compact ingot
#

an app without state doesn't do anything

drifting galleon
#

all 'state' gets written back to the components which act as pure input again in the next frame

compact ingot
#

yes, and that is NOT functional

drifting galleon
#

?

#

functional also only takes pure input

compact ingot
#

as i said, thats only part of it, FP also encapsulates the output such that it becomes pure input for subsequent "updates"

drifting galleon
#

as does dots

compact ingot
#

no it doesnt

drifting galleon
#

yeah it does

#

*referring to ecs as dots in this context because burst / jobs / etc is also included. and relevant to actual processing. still stateless

#

Ex if your holding an ar then switch to a Pistole

#

somber swift
mystic raft
#

Both

#

Pick up guns and have arm animations

tough tulip
#

Its a pretty advanced topic. There are lots of strps involved in the process to make it achievable.
To hold gun in hand, you need to parent gun to the right or left hand of the player, adjust the position correctly of the gun.
Then parent the other hand to the gun itself, so that it rotates along with gun.
Also look into unity's new animation rigging package. There are plenty of guides on it (and yes even Brackey has a video on it)

#

To pickup a gun, you need something like a trigger or something which will let your player know to pick a gun. Once you press the button to pick, you just need to automate the above process in code

mystic raft
tough tulip
#

Yes you can create your own animations in blender.
You can also use mixamo to create animations for your character.
You can also retarget any animation you find online if it's a humanoid, and you have a humanoid avatar aswell

hello everyone

#

so i've noticed that when i do dictionary.contains(null) it always returns true

#

why is this?

#

there's no key in the dictionary that equals to null

austere jewel
#

Firstly, there's ContainsKey and ContainsValue. Don't use Contains.
Secondly, there cannot be a null key ever, so the check is meaningless.

whole badge
#

ah i mean containsKey

#

i'm doing containsKey(x) and there's a possibility that x might be "" or null

austere jewel
#

it cannot be null

whole badge
#

x can be null

#

it's unclear wether x is specifically null or "" but in either case no such key exists in the dictionary, yet the function is returning true

austere jewel
#

Afaik ContainsKey will throw an ArgumentNullException if you pass null to it.

#

So x is either not null, or is Unity's fake null.

whole badge
#

fake null?

#

i'm unaware of this feature

austere jewel
whole badge
#

hmm

#

well it's not throwing that exception so the key must be ""

#

in any case though ContainsKey("") appears to evaluate true, which is definitely not expected

austere jewel
#

If x is a string then it's not fake null btw, so you can scratch that from your memory 😄

is there some quirk in Contains the i'm not aware of to cause this

Why do I need a preload scene? Why do DDOL objects work if you have a preload scene but not if you dont? The __app object is kind of confusing me, it says "You must, and can only, put your general behaviors on "_app"" what about all my other DDOL objects like a UIManager, do I put them in the preload scene and ONLY the preload scene, as a child of _app or no?

Unity game manager. Script works only one time

sly grove
#

Preload scenes do help solve a certain set of problems. I can't comment on the specifics of the other things you said or what they have to do with your error.

#

Your error just means you tried to set the active scene to the DDOL scene, which you can't do.

copper summit
#

Are you saying I tried to load a scene with a DDOL?

sly grove
#

This is not allowed

#

that's all

#

e.g.:

SceneManager.SetActiveScene(someDDOLGameObject.scene);```
copper summit
#

So all DDOL objects need to be created in the same scene?

sly grove
#

I have no idea where you're getting this from

#

You called SetActiveScene in a way that is not allowed.

#

That is all

copper summit
#

You say "You can't load a scene with a DDOL", the only inference I can come up with is put all DDOL objects in the same scene

sly grove
#

SetActiveScene is not the same as LoadScene

copper summit
#

I see

sly grove
copper summit
#

So do you mean you cant set a scene as active that has a DDOL?

#

Im not understanding what you mean by a DDOL scene

sly grove
#

WHen you call DDOL on a GameObject, the GameObject is moved to a special scene called "DontDestroyOnLoad". It is removed from the scene it started in.

#

This special scene cannot be set as the active scene.

copper summit
#

Oh I see

#

But I dont understand how one of my scenes in my build is that scene

sly grove
#

It's not

#

DO you have any code that calls SetActiveScene?

#

Does that error have a full stack trace you can share?

copper summit
#

One sec

#

I actually didn't have any code that calls SetActiveScene

#

And the error magically dissapeared

#

How odd

sly grove
#

strange

#

Perhaps a third party library or asset you are using was doing it?

copper summit
#

Possibly Im gonna look around

#

Nope theres nothing that should've caused that

I lost the original error so idk what script caused it

Also the source of a brain-meltingly nasty feature of Unity: GetComponent<x> can return both 'not null' and 'null' for the same object at the same time, within the same frame. (took a loooong time to figure that one out - it's to do with the intersection of c# method invocation and Unity's custom null check, and the scope within which Unity's custom null is evaluated. fake-null needs to die :).)

Hello!
What is the best way to get a vertex color from a large mesh near a specific world position? Is there some shader magic or something?
What we have thought about/tried already:

  1. Iterate over all vertices (Didn't tried but think the performance will be really bad?)
  2. Raycast on a Meshcollider and read it from there on collision (tried but we don't want to use mesh colliders)
  3. Custom camera with custom shader looking down that writes 1 pixel into a rendertexture with a script returning the color (seems to work kind of, but looked not so promising in profiler)
mild yew
#

@mighty ocean you could preprocess your mesh into a lookup table //in principle emulating as if it were multiple meshes

Then you'd only have the cost of iterating through all verts once and pay for a faster lookup in additional RAM

quiet anchor
#

build a BVH for the mesh, find closest vertex/triangle to query point depending on your need

#

if mesh is too large to just brute force with SIMD or something

mighty ocean
#

yeah my colleague is trying this preprocess approach atm but for me it feels a bit over-engineered for what it does in the end (detect footstep undergrounds). So I thought there must be an easier way since the information is already there.

quiet anchor
#

do you have any more information than just a point? you mention raycast and rendering... but dont see how that would work with just a single query point

mighty ocean
#

We have grass painted via vertex colors on a mesh and have the position where the foot touches the ground. Now we need to know is there grass painted or not based on the vertex color.

quiet anchor
#

so raycast from somewhere on the leg straight down?

mighty ocean
#

yes

hybrid plover
#

Does anyone have experience with syncing root motion movement over network? I have a flying dragon whose animations are made with root motion in mind. The position of the dragon gets synced which is fine but on the client the dragon always seems to be stuck in the idle animation (speed 0.5f). If I set the dragon movement to the flying animation (speed 1.0f) the client will see the dragon flying twice as fast I presume?

mild yew
#

@mighty ocean I'd preproc a lookuptable for the faces (RaycastHit gives you the hit triangleIndex) or much rather use a texture to store that info and use (RaycastHit.textureCoord2)

#

@mighty ocean ```csharp
Physics.Raycast(new Ray(Vector3.up, Vector3.down), out var hit);
var tris = mesh.triangles[hit.triangleIndex];
var vertexColor = mesh.colors[tris];

I think (?) this should give you a color of the first vertex in a triangle
#

so probably the accuracy depends on the density of the mesh, but maybe it's enough 🤷‍♂️
seems like you're using it for footstep sounds?

quiet anchor
#

raycast will give you triangle + barycentric coordinates, so you can just interpolate vertex values if needed

tough tulip
# hybrid plover Does anyone have experience with syncing root motion movement over network? I ha...

So to get things straight, you have a dragon with root motion animation and you're also syncing the position for animation?

For root motion sync, you should sync the initial point where the dragon was before the root motion begins, and also the time since the root motion began from that point.

Send these 2 data once to the other side, and then in the other client, position your dragon to the same position, and then play the animation. Speed it up until you catchup with the first client

#

The speeding up logic to catch up with first client requires some math on your end based on the available parameters, which is the catching up speed(which you need to fix), and second is the duration for how you need to keep the speed of animation to catchup with client1. And also to compensate for the duration your client took to catchup.

I dont know of its possible to move animations directly to some Xth frame. Im not sure if theres an option for that. But if it is, you could definitely try that approach aswell

I have a very difficult issue I am trying to solve, I have been trying to learn
and watch videos and read documentation, but extremely stuck. Here is what I need to do

Step 1 (Complete) Instantiate Object (Players can spawn unlimited amount of objects)

Step 2 (Complete) Add data to the Instantiated Object using Scriptable Object Script

Step 3 (Not Complete) Save that data in Json maybe using a List? I am currently using Json to save normal Data

Step 4 (Not Complete) On Start, Load that data back up

Step 5 (Not Complete) Instantiate the same amount of objects there were before, and
load the same data it had before from the list.

As the player can spawn an unlimited amount of objects, the data those objects hold
will all be different, so they all need to save and load that data. I am unsure on how
to do this, can anyone point me in the right direction? thanks

mild yew
#

wdym? Add serialization to your ScriptableObject and save them in your json list?

#

If you're already using Json to save data, why would the dynamic objects be different?

regal olive
#

I just dont understand what I need to do to complete these steps. For instance if I load something from a list thats a scriptable object, how do I then pull the data from the scriptable object that was saved

#

if it was a list of ints, its different because its just 1 variable, but a scriptable object has data within data

mild yew
#

So, you dont understand Serialization and Deserialization?

regal olive
#

I guess not

mild yew
regal olive
#

oh no i know this i already done this

#

ive already done everything with json, i can save and load data fine

mild yew
#

you can put serializable classes in other serializable classes and serialize them via JSON

regal olive
#

but how?

#

is my thinking correct in thinking that I should save scriptable objects in a list?

mild yew
# 
[Serializable]
public class ClassOne
{
    private int someInt;
    private List<ClassTwo> listOfOtherObjects;
}

[Serializable]
public class ClassTwo
{
    
}```
#

no scriptable objects needed

regal olive
#

but I need more than 1 variable saved, aswell as the objects location and how many of them there are

#

thats why i started looking into scriptable objects

mild yew
#

what the heck? You can put as much data in any of the two classes you want

regal olive
#

So, no scriptable object? so do I just attach this to the gameobject?

#

and how would i save this in Json?

mild yew
#

I think you should first figure out what you want to serialize, write a class or struct that has that Data and can pack & unpack from there

#

and please read the documentation about JSON serialization - because most/all of the things you need should be in there

regal olive
#

yeah i got no idea

mild yew
#

just look up a tutorial how to do save games I guess. It's not really an code-advanced topic 🤷‍♂️

regal olive
#

already watched many

#

and i can already save data

mild yew
#

So why can't you save the data you want to? What's different here?

I have a problem that I am going to try my best to explain.
I have a data tree of tags, each tag has an id along with a parent and a list of children. The tag tree is stored on a ScriptableObject asset (I use SerializeReference to allow circular references).
You can reference a tag in field on a components by the tag's id.
I have a TagSet class which is a collection (ICollection) of tags (tag ids).
This is where it gets tricky, I want to be able to check if a parent of a tag in a TagSet matches a specified tag.
The way I handle this currently is to have a dictionary with the key being the id of a tag and the value being an int. Every time a tag is added the id of each of it's parents is added to the dictionary if it isn't already, and the int is increased. This way when all tags that have a specific parent are removed, the dictionary entry for that parent id is also removed.

This works great, until you get to prefabs. If you use the "Revert" menu item on a tag that was added, it will either leave the count for the parents, or revert it to the count at the time it was added meaning that if you had added a second tag, the count will be wrong.

I'm not sure if this makes sense, but I am trying to figure out a workaround to this. I tried using OnAfterDeserialze, and populate the dictionary their, but that requires getting the tags and their parents from the SO which is not allowed in the serialization thread.

Ok I'm still overthinking my architecture and I'll be really thankful if anyone gave second opinion

I have this idea of managing player state with components, kinda like ecs but in oop, I guess? Like for example, I could make a component

class Sitting : IPreventMovement, IForceThirdPerson

So I can check if player has IPreventMovement in movement script and IForceThirdPerson in camera script to do sum logic but I'm not sure how to implement and if it's a scalable solution. Make a list of classes and look up when needed?

Alternatively I could just use a shit ton of bools and if statements and do something like

if (sitting | crippled | stunned | inCar | uiOpen | inCutscene) return

You get the idea, but then I'll have to modify classes every time I add a thing 😔

#

At this point I'm not event making a game, just thinking of fancy patterns

frozen imp
#

If you have complex interactions during states which will have separate configuration, a simple state machine is the cleanest way to handle it I think.

silver hill
#

It's just a bunch of independent flags to determine player behaviour at this point of concept I guess

frozen imp
#

if (sitting | crippled | stunned | inCar | uiOpen | inCutscene) return
These flags to me sound like they should be states in a state machine. Then you can easily manage them.

#

well except sitting

#

nvm, some of them look like just properties

silver hill
#

State machine sound like it's just going to complicate it, but it might be just me.

silver hill
#

Thought it wouldn't make sense for movement component to know all these things exist. Just that there's a IPreventMovement, hence no movement will be performed 🤷‍♂️

frozen imp
#

You could have an object with those properties. And pass actions through that object and it will decide what actions are allowed.

silver hill
#

Yes that's one way to do it, like a master character controller with all these properties

#

You'll still need to add a property and modify a get function every time you add something tho

frozen imp
#

But anything that has a flow should be part of state machine, i.e. Sitting -> standing -> running

#

Then you won't be able to go from running to sitting for example

silver hill
#

But you said it there're some that aren't really states

frozen imp
#

Yea, your flags were just mixed. Some of them should be states, some are part of properties

silver hill
#

Do you think the list lookup would be terrible performance wise lol

#

And code quality wise too

frozen imp
#

Not sure what you mean about list lookup. You want to avoid using just conditions with many switches, because it will very quickly become a mess as complexity increases

silver hill
#

if list(character effects) has IPreventMovement don't move

#

I guess 'effects' suits this better than 'states'

frozen imp
#

Best way to handle complexity is to separate things to relevant groups and have objects managing them.

Funny, I started with this

frozen imp
#

Like I said with flowing conditions, which go from one to another you should have state machine. For anything like health related, you would have separate "Health condition" object wich will have all those properties for ill effects, then you would just ask it on the way if your actions must be modified, by feeding action you need to do to the object.

silver hill
#

So,
if (uiManager allows movement) and (healthManager allows movement) and (vehicleManager allows movement) move then?

frozen imp
#

So it would work like "I want to switch to run from walking" -> Checks if health objects allows, object has a flag "crippled" returns instead of running -> hobbling

silver hill
#

With health condition example, when handling ill effects, this manager can add Crippled effect, then do the job of waiting a certain amount of time for the injury to heal, then remove Crippled effect

silver hill
#

A component can have something like IPreventCameraMovement

frozen imp
#

Camera should have its own separate thing

#

If you go into cinematic flag the camera as locked

silver hill
#

A certain type of vehicle could disable camera movement, for example

frozen imp
#

That would be best related to "movement state" machine. When you go into from walking/running/crouching into -> Getting in the car animation state -> Got in the car (will check if it needs to lock the camera depending on the car)

#

And health properties would be modifier that each state checks

#

governed by own object

#

So everything is separated and extendable in the future.

silver hill
#

Sorry, just don't see the benefit of splitting things so much yet. In theory component solution is easier to use, as in
A player gets in a car, a InCar effect gets added, which has IPreventMovement and IForceThirdPerson, they then open a ui, which adds some effect with IPreventLook

Movement and camera components only need a reference to character effects controller, so do things that give said effects. Would it be better to have movement component hold a reference to controller, controller hold references to vehicleController healthController and whatever, and effect givers to controllers of their type?

#

I guess effect component would be monolithic and separate controllers modular

#

Yeah you know I'm reading this over and it starts making sense

#

Different components handle their own thing and a master controller compresses them down to a bool

frozen imp
#

A player gets in a car, a InCar effect gets added...
This doesn't exclude state machine for movement flow.

#

It's something that can be managed by the current state

silver hill
#

So I would call to character controllers CanMoveCamera and it will check current health condition, ui, and vehicle

So I am making a roll-a-ball feature and I am wondering how I am meant to get it to be like the second one, a bit like Monkeyball I assume

mspaint_2022-01-26_13-29-25.png
#

Right now the addforce is single inputDirection * accelSpeed and all that, but I want the addforce to somehow go along the normal

#

I dont know how to angle AddForce in the direction like I am imagining it

#

Use Cross product between the normal and.. what?

compact ingot
# 
myNewOrthoForce = Vector3.ProjectOnPlane(oldForceDirection, normal).normalized;
fresh salmon
#

(ProjectOnPlane "flattens" a vector onto a plane which normal is normal, so here you get a plane the same orientation as the ground)

chilly tree
#

Ohhh

#

That is super useful

#

I feel like a whole new world just opened on things you can do with that

Hey, I've got a weird problem. On an app, I must find a photo. So on Android, I just used a file browser, and it's just a matter of finding the file. But on IOS, apparently, all aps can only access certain files ? So basically my file browser can't find the photo. How do I say I want a particular photo to be accessible to my app? When I go on a Mac, and try to add the photo to the files associated with my app, my app doesn't appear. Is there something I must do to declare that my app wants to access files and appear on the list?

Hello everyone, I need help with something that's bugging me for a couple of days now.

I have 5 different arrays, each has different amount of things in it.

What I want to do is, generate all possible permutation/combinations from these 5 arrays to generate uniques.

Every possible thing will be generated.

Usecase; I have 5 different game objects; legs, hairs, arms, body, eyes. They all have an array of possible sprites. What I'm trying to do is generate all possible combinations of characters at once and be sure nothing repeats and nothing is lacking

ocean raptor
#

Oh that's easy

#

You do nested for loops.

#

And then prepare for the machine to take a moment because things like that are OnX operations

#

The time to execute increases exponentially with the size of the arrays and the number of arrays

Hi , can you help me with skinned mesh renderer . My question is if there is way to reduce drawcalls when using same skinned mesh and material . Im not looking for texture baked animations or Crowd animator controllers or these kind of gpu instancing .. Also ecs/havok physics i don t want to use .. I m looking for any way to merge it but maintain functionality of the gameobject so i can use ragdolls/physics and animator .

plucky laurel
#

wouldnt that be inneficient?

fervent dust
#

We r talking about low end android device .. actually 70 drawcalls with low poly stickmans ahve huge impact on performance

#

I have fully optimized scene with basic setups

plucky laurel
#

but merging meshes on runtime on the cpu every frame would certainly be less effective than just leaving it to gpu

fervent dust
#

Oh , and is there any way how to improve performance ?

plucky laurel
#

the only way i can think of is by using the baked anim technique and swapping for real mesh rendererer when you need ragdoll

fervent dust
#

Oh yes that sounds good but any tips how to check for collisions ?

plucky laurel
#

i have no idea what your scenario is, i would start with approximating

#

bounds checks, etc

fervent dust
#

Okay, good thank you

plucky laurel
#

you can, theoretically, if you have the time, to implement something similar to quake1

#

something like - have your skeletons in the scene, do your own skinning, do that in a job, for each agent

#

in quake1 they used baked anims stored in an array, the game then would interpolate vertices, similar to texture baked but without the shader part

#

you could in theory maintain both skeletons in the scene with colliders, without skinned meshes, and bind a mesh in your own batched skinner

fervent dust
#

That's interesting i try it .. Thanks , appreciate your help.

So it will happen via a nested for loop it seems

Hey frens ✨ 👋 Anybody here using firebase realtime database for a multiplayer game with a lot of users?
I'm familiar with Mirror but with about 100 users tops per server it's not gonna cut it unfortunately. I'm also not looking for something ultra tight sync wise, more like have player's vector3 positions and sending messages accross like chat..
Wondering if someone here has experience with it or some advice? 🔮

Does anyone know of basically a push event system for Unity? Something where I can trigger an event (either in Unity or on a server) and fire off a message to all subscribed clients? I've seen firebase but I'm having some issues with it.

hello does anyone knows how I can make a game tilemap based but the Z (height) with a different angle? For example like tibia/ultima the Z is 45 degrees.

Or alternatively, how can I change the X or Y axis too?
Example: earthbound has a Y axis in 45 degrees

Or isometric, X and Y is bent and Z is straight from the ground.

Been googling hard about it lately but no success whatsoever

So apparently learn.unity.com has a course on behavior trees. I didn't know about it because it doesn't show up when you search "behavior trees." But there is a beginner ai course out there. It's decent

regal olive
#

Random thought: do you think the game creators in the world of West World (s1) used behavior trees for their 'hosts'?

Probably a combo of BTs for stimulus and GOAP for larger goals throughout the day. 🤠🐴

plucky laurel

some form of fuzzy logic would be more likely

I can't use the asset store in my projects. I work in open source and unity doesn't currently support using the asset store from a CI/CD context. I'm reverse engineering the API to be able to do it now but right now I can't 😦

#

I don't want to work privately because... well I want my code to help others. Game programming is very challenging. Contributing to the global ledger is important ^^

plucky laurel

i think its this one

#

ive read it years ago, so dont remember if its the one

#

ah no thats sims 1 😄

regal olive
#

Word. Well the sims is definitely on my radar. The concept of "smart object" (object that has its own behavior tree defined) comes from the sims IIRC. I knew the name of the programmer producing the papers and looked up their talks. I still have yet to implement smart objects myself, but its on the list

I could use some help on this. I want to disable the Unity 2DShadowCaster component in a script but the issue is I don't know how to reference it because it's not a monobehavior I cant get it with the GetComponent<>().

#

Figured it out it was just really weird

#

for anyone else you have to use allll this GetComponent<UnityEngine.Experimental.Rendering.Universal.ShadowCaster2D>();

austere jewel
#

using UnityEngine.Experimental.Rendering.Universal; (UnityEngine.Rendering.Universal in latest URPs) would mean you can just refer to it normally.

#

You can get your IDE to add/suggest namespaces automatically

Anyone see the problem here? What I'm trying to do is send a TryCastEvent, giving listeners a chance to Invalidate() it, and then only send a CastEvent if it hasn't been. It's currently ignoring IsInvalidated(). Ping me if anyone has any insight, please.

AbilitySlot.cs:

private void TryCastAbility() {
        var tryCastEvent = new TryCastEvent(Ability,actionBar.Player);
        EventBus.Raise(tryCastEvent);
        if (!tryCastEvent.IsInvalidated()) {
            Debug.LogFormat("{0} has not been invalidated!",Ability.Name);
            CastAbility(tryCastEvent.Ability);
        }
    }

    private void CastAbility(Ability inputAbility) {
        AbilityCastArgs castArgs = new AbilityCastArgs();
        castArgs.CastingPlayer = actionBar.Player;
        castArgs.TargetPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        castArgs.AbilityScriptableObject = AbilityScriptableObject;

        EventBus.Raise(new CastEvent(Ability,castArgs));
        //StartCooldown();
        Debug.LogFormat("Casting system should call StartCooldown()");
    }

My listener event handlers, elsewhere:

private void TryCastEventHandler(ref TryCastEvent eventData) {

        if (eventData.IsInvalidated()) {
            string debugString = "Invalidated!";
            for (int i = 0; i < eventData.Log.Count; i++) {
                debugString += string.Format(", {0}.",eventData.Log[i]);
            }

            Debug.LogFormat(debugString);
        } else {
            Debug.LogFormat("TryCastEventHandler({0}) ",eventData.Ability.Name);
        }

        // Check if caster has enough mana to cast the spell.
        if (eventData.Caster.Stats.Mana < eventData.Ability.ManaCost) {
            Debug.LogFormat("Invalidating {0}", eventData.Ability.Name);
            eventData.Log.Add("Not enough mana!");
            eventData.Invalidate();
        }
    }

    private void CastEventHandler(ref CastEvent eventdata) {
        Debug.LogFormat("CastEventHandler({0})",eventdata.ToString());
        eventdata.Ability.Cast(eventdata.CastArgs);
    }

Invalidated stuff, in TryCastEvent (constructor defaults invalidated = false)

private bool invalidated;
    public void Invalidate() {
        // EventBus.ConsumeCurrentEvent(); // May cause errors if used, could consume wrong event (needs confirmed) probably less confusing to just do it manually anyway.
        invalidated = true;
    }

    public bool IsInvalidated() { return invalidated; }
#

Output:
I'm thinking maybe it's not being Invalidated before it reaches if(!tryCastEvent.IsInvalidated()) but I don't think so. I'm pretty sure this should be fine

Stepping through it, it looks like the event handler is being called after the if statement

regal olive
#

@unkempt nova you nailed it; exactly right. Also, this is an uh oh setup because you are fighting with your decoupled setup.

I haven't considered this deeply but do consider an alternative setup... maybe use two events instead of one for this? Or maybe this isn't a place for events given an invalidated state is defined by collaborating classes

unkempt nova
#

I'm being told my eventData is being copied, twice. I think that may be it

regal olive
#

Hmm is that so? I never considered if events were copied or a ref passed in. Sounds like the former based on what you say

unkempt nova
#

I'm not sure. Person saying it may be being copied is no longer clear on the cause now

I got it rolling. I was forgetting ref and in for my calls. DERP. Thanks, comrade mudkipz

how do i do public class Player : GameObject?

flint sage
#

You don't

fresh salmon
#

Welcome to #archived-code-advanced. As GameObject is sealed, you can't inherit it. If you don't know what that means, pick another channel :)

steel moss
#

can i make it to not to be sealed via c# sources of Unity?

#

I need Player for example to be an object, not a component

fresh salmon
#

Not possible, no

#

Sounds like an XY problem

#

So why do you need it to be an object

steel moss
#

There is not prototyping reason, there is logic issue in general, i dont understand why Player is a component, while for example Mesh of the Player is real component, but not Player, Player is an object

#

Vertical hierarchy lost there with sealed gameobject class

fresh salmon
#

Player is a GameObject, with a set name. A GameObject can have one to n components attached

#

I don't see what you mean

steel moss
#

if i cant do GameObject as Player it is not true

#

Alright, i can show you on example what i mean

fresh salmon
#

Of course you can't do that, you're comparing GameObjects to Components

steel moss
#

Yes, thats my point, why forcing Player to be component and break logic?

fresh salmon
#

Break logic?

#

You'll need to elaborate and provide an example as I don't see how it could break logic

steel moss
#

With normal logic, you have weapon inherited from entity, weapon itself is and entity and not a component of some abstract gameobject

#

This one for example

#

Unity breaks this logic when anything is components of faceless nothing

fresh salmon
#

You can make class that aren't components, by not deriving them from Component or its derivatives, and still be able to use them

steel moss
#

And place in the world?

fresh salmon
#

What

#

You place GameObjects in the world

steel moss
#

Yes

fresh salmon
#

You can't place classes alone, it doesn't make sense

steel moss
#

Yep thats why am asking

#

I need placeable entity with Transform component

#

GameObject is what i need, but i want inherit it and override some functions

fresh salmon
#

So no, it's not possible. Only GameObjects can be placed in the scene, and only GameObjects can have Components attached to them.
And since you want to have a component into the scene, you need to attach it to a GameObject.
You can of course inherit from Component manually, so you have the very primitive class that can be attached to a GameObject, and provide custom implementation

steel moss
#

Got it, thanks, any ideas why it is made so unlike in other engines?

fresh salmon
#

I've never touched other engine, so I can't tell.

#

The only thing I do outside of unity is regular Windows Desktop apps

flint sage
#

It's not necessarily different from other component based engines

#

Sure it's not like your average OOP application

#

(also sealed classes have a place in OOP as well)

regal olive
steel moss
#

I worked about 5+ years with Source Engine so that i cant inherit GameObject was like a shock for me...

#

u just do final class CMyEntity : public CBaseEntity and u go

regal olive
steel moss
#

if u want custom entity like idk ReflectionProbe, u just do final class MySpecialEntity : public CEntityInstance

steel moss
#

it is true

#

see no reasons why just not open C++ source code?

#

they would not loose money on it

#

and plus for devs who work with C++

#
  • to perfomance
#
  • engine would support modules
regal olive
#

Umm. Yea I don't know who even to ask to get an answer to this. Who is the primary brain/s of the decisions of unity as a game engine?

steel moss
#

some guy in Unity Technology xD
