then compare the sorting index

rich storm
#

i need an object's sorting layer or depth or something

#

can a box collider 2d detect multiple collisions?

compact ingot
#

if they are all at the same distance, then there is concept of "a closest one"

compact ingot
#

if you use collision/trigger callbacks you get one callback for each other collider, so you would have to keep a list manually over multiple such callbacks to have a list of all collisions that occur inside one update... that is not an elegant way to do it, so better use a raycast.

rich storm
#

So how do I replace what I have, I'm pulling the code in a minute

sinful fossil
#

How would I go about creating a component input in the inspector with a editor script. I want to have an input that references another gameobject component but with the GUILayout or EditorGUILayout?

rich storm
#

@compact ingot ?

#

Or if you do use Find, it's in Start, and not on every collision

true cosmos
#

can we store in json or scriptable object refereces to scene object using local identifier in file from scene files?

#

like hook up into serialization during loading game save, and store reference to monobehaviour using this LocalIdentifier from scene file

compact ingot
tough tulip
#

Another approach is to make prefab of those gameobjects, reference them to scriptable object, and then reference that one scriptable object to scene using another gameobject and a script.
Its like beating the bush, but gets your thing done

flint wind
#

It's something I'll have to solve eventually too. When my procgen plants items, it will need to ID them. Then a save file can regenerate the level based on the saved seed, and regenerate the same items with the same IDs, but then also remove the already picked up ones based on ID

true cosmos
#

my problem is to save randomly generated quests, and those quests can reference scene characters' objects

#

if there was some unity method to get object from scene from its Local Identifier in file, but it needs to work on build

flint wind
#

You'll need a way to generate an ID for scene objects that will ensure the ID never changes when you reload/replay the scene

true cosmos
#

yeah, well i can serialize my own guids, but i was hoping for some built-in solution 🙂

flint wind
#

The simple way, but prone to user error, is to have a string on the object that is its ID. If you don't have many scene objects to track, this might work fine. As long as you never accidentally reuse the same ID, you're good.
If you have a lot, or you're using procgen, you'll need some algorithm that generates the ID in a reproducible way

#

Unfortunately no built-in unity method for it. Probably to dodge painting devs into a corner with a setup that only works for some use cases

true cosmos
#

@flint wind so basically if you have to reference scene files from SO or json save files you need your custom ID system? 😦

flint wind
#

Essentially. But there's many others who have tackled this, so google searching should turn up tutorials and other peoples' articles on the matter.
Part of the reason is that Unity's own gameobject ID system is not guaranteed to replicate the exact same way for everyone. For you, the number is 8345789, and might always be that, but someone else playing gets 190286563

true cosmos
#

yeah, but there is a difference between instance ID of every UnityEngine.Object and LocalIdentifierInFile. instance ID differs among computers, playmode sessions, scenes loaded but local identifier is serialized in any asset files to keep references within them.

#

so creating custom id system seems like doing the same thing in parallel :\

Hi, I'm trying to make a server side movement validation to reduce possible speedhack in my game but I'm facing a wierd problem. Every fixedUpdate, the client calculates his position and then send it to the server with the inputs. The problem is that the server doesn't receive every ServerRpc calls. Could it be due to lost packets ? Cause I really don't know why the client calling the movement function but not the ServerRpc one. Here's a little part of my code

edit : the client is calling the serverRpc but the client still manage to move faster than the server cause it's missing frames

#

You probably need to look into some solutions for call/verify behaviour with the server

#

Basically, the client sends the input, but does not process it until the server replies. This will however effectively mess up real-time responsiveness

#

unless you assume it is valid and only react to the server responding to say something is invalid. Do you need to know if each input is valid or could you get by with only knowing 1 in X? If so then its not a big deal if some responses don't come back

#

Also, this is just brainstorming. I have not done this myself, so this is just me spitballing ideas

inland halo
#

line 129 + correct, it should work

idle bridge
# hoary crater You probably need to look into some solutions for call/verify behaviour with the...

To have a good feeling with movement, the client is making the movement by itself and then it send the inputs to the server. Then, the server have the same code and at the end, if the Vector3.Distance between the transform.position and the one from the client is less than 0.01f, the movement is right and it doesn't respond to the client since it's already to the correct position. The problem is that sometimes (idk why), the client moves to the next frame but the server just don't get the update. So for the next frame that pass to the server, the deltaPosition is ok but the client and server haven't start at the same place. sorry if it's confusing

true cosmos
#

@idle bridge what network solution are you using?

idle bridge
#

and photon realtime for the transport

true cosmos
idle bridge
true cosmos
#

I will follow this topic here though, cause it always bothered me, what happens to lost udp packages when youre using client side prediction ;D should they be re-sent if they got lost or what

compact ingot
#

the transport handles that (what happens with lost packages)

idle bridge
#

I have no idea why the ServerRpc doesn't get call then

compact ingot
#

if its causes by lost packages you'd get inconsistent behaviour, seems you get a consistent error though

idle bridge
#

it's inconsistent...

compact ingot
#

then it can be lost packages, a race condition or maybe thresholds that are too tight

idle bridge
#

ho

#

Is a fixedUpdate of 64 frames/s too high? like the server framerate is 64

#

at the same time it should work? I'm so lost xd

compact ingot
#

fixedupdate is independent of update

idle bridge
#

Yeah, all the code is in fixedUpdate for now

compact ingot
#

if they are both the same there is no guarantee that they are interleaved perfectly

idle bridge
#

it's why idk why frames are missing since it's suppose the call server every time

compact ingot
#

how do you test if the RPC is received by the server?

idle bridge
#

I debug.Log the position the client predicted and the server predicted and after a little time, the positions starts to be.. like not in order. The client goes faster. The server can't handle missing frames cause the deltatime is always the same. so it can't adjust

compact ingot
#

maybe you need a more complex prediction algorithm?

#

The comments are separating what class they are coming from

#

actually let me just add that

#

so in the drone component editor script, i check to see if the "Link Manager" object field is changed from previous

#

if so then run the LinkToManager method in myDroneComponent

austere jewel
#

If you mean either manager or something you do in LinkToManager is not persisting, then you need to either use Undo, SerializedObject, or SetDirty.
This is a topic for #↕️┃editor-extensions, where that is pinned

sinful fossil
#

when you say "use Undo, SerializedObject, or SetDirty" what do you mean?

#

on what

compact ingot
#

on the target object

I'm creating UI elements at runtime, and assigning on click events to Buttons.

For some reason, it seems as though the newly created elements only ever call the OnClick method on the first button that was created.

I've scoured through for hours, even refactored a few times and I can't seem to solve this issue.

Is anybody able to take a look with me?

# 
GameObject CreateNewStatLeaderboard(string type, List<LeaderboardEntry> leaderboard)
        {
            GameObject list = Instantiate(statList.gameObject, statParent.transform);
            list.name = "LIST - " + type;
            UnfoldList myList = list.transform.GetChild(0).gameObject.AddComponent<UnfoldList>();
            list.transform.GetChild(0).GetComponent<Button>().onClick.AddListener(myList.TogglePanel); // += myList.TogglePanel;
            myList.Setup();
            list.SetActive(true);
            CustomiseStatList(list.transform, type);

It's extremely straightforward stuff

anyone know how to render a mesh with drawmeshnow using the gameobject layers? I am using a feature in URP to render out all ovjects in this layer infront of everything else. But I need that to work with drawmeshnow. Anyone know how I might do that?

sly grove
#

DrawMeshNow doesn't use layers. It literally just draws the mesh, right away.

#

Hence the name

sinful fossil
#

right, but is there any way to get the effect I am looking for

sly grove

Other methods like Graphics.DrawMesh have nicer integration into the render pipeline

@hoary crater @compact ingot I found why the serverRpc wasn't working... I feel really stupid xd
I was doing a simulation to go back at client time to make the movement and then validates it, but the simulation wasn't saving the correct tick so, sometimes, nothing was saved for a tick. I found that I made a return in this case... I'm really sorry and thank you for your help 🙂
by returning, the server wasn't changing his position but the client was
if (!FramesData.ContainsKey(key1) || !FramesData.ContainsKey(key2)) { return; }
I don't even know how I didn't realised that before...

I've been running into a netcode error and traced it to a possible line change that cna fix it. problem is it's in a script in a package. and when I change it it just changes back when "reloading" unity, is there a way to make this fix stay?

I have a function that creates randomized platforms from individual "blocks".

Is there any way to have the blocks next to each other be "Stiched up" into 1 collider? while the rest remain their own collider?

I have tried to have individual box colliders. However sometimes my character gets "stuck" due to the collider beneath

unknown.png
#

i have used compositecollider, but that makes the platforms that are not sticking to each other under the same collider

novel wing
pseudo dune
#

well i am not planning to do manually, because im making a random platform generator for the game

#

does tilemap and grid stich them up? making them like 3 different colliders, that is fine

#

as long as the entire thing is not treated as one, or treated as many single blocks

#

how are tilemap colliders different than boxcollider2d though

novel wing
#

Manually shouldn't be that hard if it's aligned to a grid. Just go row by row, left to right. Find first block, keep looking to the right for empty space, when you find it make a box encapsulating the first and last block. Repeat until row complete.

novel wing
pseudo dune
#

uhm, it's not about manually making the colliders. I'm trying to generate a spleunky type map.

#

are you perhaps referring to compositeCollider2D with tilemap colliders?

novel wing
pseudo dune
#

well this is the one that is preventing what i am trying to achieve though

#

because using composite, the above platforms will be treated as 1

#

and it will be hard to "extract" each corner of the collider

novel wing
#

Can you show an image of what you mean with "the above platforms will be treated as 1", because from my understanding this is what you want?

pseudo dune
#

sure, here is my current code and a short video

#

basically, i extract the information of the "composite collider" for the coordinates of the corners. And once the character's feet does not detect ground, it will "snap/teleport" to the corner (hence the distance comparison code). to do a rotation, then continue moving.

pseudo dune
#

composite collider 2d , could work, but i have to find another way to "snap" into corners

novel wing
#

But if you end up using that you'll have to figure out the corner problem like you mentioned

pseudo dune
#

yeah. that's right

#

the problem is if i use the raycast, to detect ground, it will go past the corner before starting to rotate

#

which creates a gap depending on the speed of the character

novel wing
#

err

#

Tilemap & grid

pseudo dune
#

currently im not using any tilemaps

novel wing
#

Yeah I know, I meant in case you end up changing

pseudo dune
novel wing
#

You can still use a raycast though, use a shaped raycast instead of a single ray

pseudo dune
#

i have used circleoverlap, circle cast before, those are not really the best as they create a weird interaction

#

in the above video, you can see how it cant move past 3 blocks, at least not until the character turns around, rotate once and back again

Hi, I'd liket o negate effects of Time.timeScale on my jump and nobody in #archived-code-general or #💻┃code-beginner was able to help me:

    private void doJump()
    {
        rigidbodyComponent.AddForce((Vector3.up * (jumpVelocity)) / Time.timeScale, ForceMode.VelocityChange);
    }

The problem is I just fly up in the air when the time is slowed down and I jump

novel wing
mental escarp
#

let me try

novel wing
#

no it was more of a design question

mental escarp
#

well it's set to 0.25 now

#

I'd like to have something like a speedster player class that can slow down time but it doesn't affect him so I did it for left-right movement but I am having some trouble with jump

compact ingot
mental escarp
#

here is what I did for left-right movement:

        //Better Movement
        rigidbodyComponent.velocity = (new Vector3(movingDirection * horizontalPlayerVelocity, rigidbodyComponent.velocity.y, 0))/Time.timeScale;
mental escarp
compact ingot
#

by having a system that manages every pawn's velocity based on your bullettime feature being active

#

with timescale staying at 1

mental escarp
#

isn't it easier to change 1 player instead of everything else?

#

I still want everything to be slowed down just his movement speed to be normal

compact ingot
#

and probably a few other things

mental escarp
#

I mean it's just his speed

#

bullets he shoots and all that stuff should still be slowed down

compact ingot
#

i guess as long as timescale wont go too low it should work

mental escarp
#

yeah but I still don't know what's wrong with my doJump function

#

everything else seems to work fine

compact ingot
mental escarp
#

no

compact ingot
#

my guess is, you would have to update the whole physics simulation for your character to compensate for the timeScale

mental escarp
#

I want just a normal jump

#

well that's all the physics I have for him

#

left-right movement and jump

compact ingot
#

you arent doing any physics, the engine does that

mental escarp
#

yeah but my left - right movement works fine isn't it the same for up-down movement?

#

I can send you my whole code if you'd like to see it

compact ingot
#

no, because the jump relies on gravity that is applied by the simulation and not your overrides

mental escarp
#

so I should change the gravity somehow?

compact ingot
#

just add a scaled version of the gravity to your character with ForceMode.Acceleration in every FixedUpdate while bullettime is active

mental escarp
#

but it isn't always in the slow motion should I do it in the slow motion script then?

mental escarp
compact ingot
mental escarp
#

so I should change velocity.change to acceleration?

compact ingot
#

thats not what i suggested

#

maybe read it again

mental escarp
#

guess this is way too advanced for me, I'll come back to it when I finish other parts of the game

compact ingot
#

(make sure you consider the gravity that is already applied by the physics sim automatically)

#

its really basic physics... maybe you have to think a little bit about what you are actually doing to the physics when changing timescale

#

imagine your game remains in normal timescale... what you are doing now is just add a bigger jump because the gravity remains the same... what you actually want is a faster jump with the same arc, and that happens when you increase the jump's launch velocity and the gravity that brings it back down... the arc will be the same as for all other objects, but it will be faster proportional to timescale. Then if you play that world in the lowered timescale, your character will seem like it is at normal speed.

I'm building a map at runtime. it's a 2d map using 3d tiles -- basically 3 states for each tile: pit, floor, wall -- what's the best way to actually render this all out at runtime? it seems like creating an individual GameObject per tile would have terrible perf quickly...

#

currently the map is 64x64 (meters) -- would be nice to have option to go up to 124x124

compact ingot
rugged pollen
#

example map:

unknown.png
#

yeah the tiles would all be static

compact ingot
#

best is to test how far you can take it

rugged pollen
#

alright, well if there's no reasonably easy alternative to just spitting out GameObjects that's what I'll do till I start hitting issues

compact ingot
#

i'd go with a more complicated approach only if it doesn't work performance wise

rugged pollen
#

yeah, don't want to pre-optimize but also if there's something straightforward I can do which is known to work might as well start down that path

#

but all I can think of is trying to generate meshes at runtime, which doesn't seem simple

compact ingot
#

its not premature really, its a fundamental decision you cant easily change later

compact ingot
rugged pollen
#

lol that'd definitely be beyond me at this stage

compact ingot
#

if you want crazy numbers of (active) tiles on screen, you'd probably have to dive into DOTS

rugged pollen
#

I think in practice there won't be too many currently running an ortho camera w/ size = 4, so it's pretty tight and may zoom in more we'll see

#

guess I'll start w/ the stupid way, 64^2 tiles/gameobjects and see about fusing 'em together at runtime later

take a look at Broforce if you want a reference for what level of detail is easily possible with 1 gameobject per tile

(net cut out) -- yeah wouldn't one giant level mesh collider be worse for perf? I guess I assumed it would

high mirage
#

crazy question but I'm thinking of making a doom "port" in unity

#

what I want is to have doom, in unity

#

it's probably a stretch and maybe emulation is what I need? but I have no idea

#

if anything, i have no idea how to run an emulator IN unity

#

I'll probably be better off making an emulator instead of making the game using the source code and assets

#

so I'm wondering if there is any emulator that can run in unity?

#

and if so, what can it run, how does it do it, so I can get an idea of what to do

why don't you just build it from the ground up?

yes

there's definitely something appealing about minimalism like that. I agree that the above is pretty 🤮

compact ingot
#

i'd say if you want a non-smooth look and steep walls commonly > 45°, terrain is not the way to go

#

i'd go for individual tiles and "bake" them into a single mesh-terrain when the level design is complete

How would I assign a scriptable object in my settings to be used globally by static functions for example?

unknown.png
#

as example the graphics settings in unity ^ where they also use a scriptable object and assign it

#

Or is the best way to go about this just loading one from the Resources folder?

rugged river
#

@snow grottoYou can assign scriptable objects at runtime, if you place them in the Resources folder

#

@snow grotto For example, if you have a SO of type BoolValue in your Resources folder (you can have subfolders like I have here), you can assign the SO at start like this: ```
[HideInInspector]
public BoolValue MyScriptableObject;
protected void Start()
{
MyScriptableObject= Resources.Load<BoolValue>("ScriptableObjects/NameOfSO");
}

I'm doing that at the moment, I guess it woks fine. It would be nice to be able to assign it in the project settings somewhere though

Oh, maybe you can do it by writing an extension or something?

I have a script that should sit in th eeditor and scripts folders each, same script. I am wondering if I can add compiler directives to enable this? I need to control the class derivation too: EditorWindow and MonoBehavior.

#

And does any body have any info on using #include to use files. This seems to me to be outside of the way Unity folder structure is setup. How does Unity handle *.h files?

#

This way I could have an H file that houses the variables and pull that into either EditorWindow or MonoBehior scripts.

#

The main goal is to one script that can be placed into the scripts and Editor folders.

you have to let go of your C/C++ concepts, header files don't exist in C#, a script in the scripts folder will also be automatically visible to any script in an editor folder (or rather the assembly that is compiled for editor use from those files in the editor folders). You can put a preprocessor command #if UNITY_EDITOR ... #endif around any code in any folder that you want to compile only inside the editor.

I've had some success with having another project generate a DLL and deploy it to my unity projects

#

It's not the .. best approach for everyone, but it works for me for my use case since my unity clients are a small subset of my total project

strong hinge
#

Yes. I would like to create one script and drop it into both folders but the compile and location has problems.

misty glade
#

I don't have Unity open atm, but you really can't just using in your Editor script to reference the methods you need access to?

strong hinge
#

Yes. I am close in this. But the duplication of variables is what I am trying to avoid.

misty glade
#

Maybe I'm not understanding.. do you have a singleton that you want to find and reference from your editor script?

#

Like, what are you trying to do? And.. are you super experienced in c#? or is this more of a beginner question?

strong hinge
#

40 years in C. No singletons. I have methods and data declarations that exit in two scripts at the moment. They are the same but the Editor has onGUI and editorGuiLayout. I want to maintain one script and drop that into both folders so I can use from the Unity menu bar and also attach to GameObjects. The script grew from a gameobject script to a editor script. My devlopemtn then grew the editor script and I now need that back on a gameobject too.

#

The script has to be derived from EditorWindow and MonoBehavior to reside in the respective folders and work correctly in Unity.

#

This is only to reduce the 'double editing' on two files.

I need some help. "How do I install an asset store asset from within a github action?" is the overall question I'm seeking to answer in my programming session right now.

Context:

I'm kind of having trouble. If anyone can help, that would be awesome!

#

Code of what I've tried so far (failed; unknown package identifier because com.synty.PolygonStarter was a guess)

using UnityEditor;
using UnityEditor.PackageManager.Requests;
using UnityEditor.PackageManager;
using UnityEngine;

public static class UnityBuilder
{
    private static AddRequest _request;

    [MenuItem("UnityBuilder/Install Asset Store Assets")]
    public static void InstallAssetStoreAssets()
    {
        Debug.Log("Installing!");
        _request = Client.Add("com.synty.PolygonStarter");
        EditorApplication.update += Progress;
    }

    private static void Progress()
    {
        if (_request.IsCompleted)
        {
            if (_request.Status == StatusCode.Success)
                Debug.Log("Installed: " + _request.Result.packageId);
            else if (_request.Status >= StatusCode.Failure)
                Debug.Log(_request.Error.message);

            EditorApplication.update -= Progress;
        }
    }
}
#

My .gitignore looks like...

/[Aa]ssets/PolygonStarter.meta
/[Aa]ssets/PolygonStarter

The observable side effect that I'm looking for right now is being able to install this package from just my C# script from the MenuItem attribute. If I can do that, I'm basically done.

No. The package manager window lists the asset store assets you have and just downloads the .unitypackage and puts in folder somewhere and then imports it.

The best way I can imagine you doing this is, open up a new unity project, import the asset, git init that package, make a package by putting a package manifest file, and push it to a private repo you have.
Then you install it via the git url.
the disadvantage of this is... the package installed through the package manager (the ones with the package manifest file) is now immutable.

Hmm. Cool, I think I know how I could achieve this. Still, I wonder if there is a better way?

Is there a scripting API for the asset store? I couldn't find some documentation for a C# scripting API for asset store assets 😦

#

@violet schooner No worries, ha. Want to join me on this journey? I just stumbled on https://publisher.unity.com/access

(edit) dead end >.< There is an API to managed your own asset store assets but not others (like from Synty Studios)

#

I'm kinda grasping at straws, though. I'm hoping I can figure out how to programatically download and install asset store assets from a C# script <.<

If anyone has already done this, help would be much appreciated!

Is this the 'correct' way to handle server & client separation?

#

I know there's many different ways, but. I'm just having it disable either the Server or Client component under the shared (top) one depending on which version is running. But it means any script with both a server and client aspect will require three scripts total, so it bloats the hell out of the inspector.

Just doing if (isServer) or etc. seems very inefficient though so I'm not sure. Is there a better way?

if you cant see them from either side they don't exist or have zero area, or you have alpha clipping at 1 or you a transparent material that hides them or messes up the sort order.

Okay need some help with this.
I use a custom render pipeline to support a specific Oculus tech (SpaceWarp) and my current shaders don't support it.

If I build for android I want to change the shaders of all materials in my game to the simple lit shader. At runtime I just do .shader = simpleLitShader, but that gives graphical glitches because of spacewarp.

Now I am trying to do it in the build process, using the code below, but the materials stick with the old custom shader and not simple lit.
I also tried .material instead of sharedMaterial

Does anyone know if me or my code does something wrong?


public class ShaderSwitch : IProcessSceneWithReport
{
    public int callbackOrder => 0;

    public void OnProcessScene(Scene scene, BuildReport report)
    {
        foreach(GameObject go in scene.GetRootGameObjects())
        {
            var renderer = go.GetComponent<Renderer>();
            if (renderer)
            {
                var tex = renderer.sharedMaterial.GetTexture("_Diffuse");

and then on the second object, it's Count is 0 again

and 0 again for the next object :/

sorry for the mess.

#

It's a generic type. Are those all from the same closed generic? Otherwise, maybe you have let the list escape by returning it somewhere and something is modifying it

all classes where you're adding items to list*

ignore the rest of the code.

tough tulip
#

there is one possible explanation for this. despite a field being static, it is not shared among different generic types.

real blaze
#

I changed teh list type to object

tough tulip
#

the only way to avoid something like this is to put your list in some other non generic class

real blaze
#

with the list as object, it's the same

unknown.png
real blaze
#

but I believe C# has a feature for this situations. it seems very unproductive to have to make a helper class just for the generic static variables

#

@tough tulipyes your suggestion worked. thanks

#

(but at the cost of a new static class as a helper)

unknown.png
tough tulip
#

generics behave differently with static classes because generic class type 1 and generic class type 2 have completely different memory footprint depending on their Types. so they're entirely different classes

real blaze
tough tulip
#

no

real blaze
#

it's a shame really

real blaze
#

@tough tulipseems like there is a solution for that

#

a nongeneric abstract as the parent of the generic abstract

tough tulip
#

isnt that same as having a helper class? either way you''re needing a new class

real blaze
# 
    public abstract class GenericClass
    {
        static public List<GenericClass> instances = new List<GenericClass>();
    }
    public abstract class GenericClass<T> : GenericClass where T : SomeOtherClass
    {

I am creating a texture from code. These are my UVS, one simple triangle on the texture.

float triHeight = Mathf.Sqrt(3) * 0.5f;

Vector2[] uvs = new Vector2[] { new Vector2(0.5f, 0), new Vector2(0, triHeight), new Vector2(1, triHeight) };

Now I am to create the texture, and for each pixel I want barycentric coordinates matching the uv specified above. How would I best do this?

Obviously trying to avoid a full ray/triangle intersection since I have so many constraints that should be able to speed the math up

#

actually i think i got it..

yup, pretty close

I'm late, but you should normally be able to loop through the array to sum all the vectors, then divide by the length of the array to get a mid point.
That's how we do it in 3D, not sure if it's the same for UVs and whatnot

Hey quick question, what is the difference between ComputeBuffer.Dispose and ComputeBuffer.Release?

compact ingot
#

Dispose zeroes the pointer to the buffer and notifies the engine it is no longer needed

#

Release probably exists for compatibility or legacy reasons, Dispose is part of the IDisposable interface and allows you to define a scoped variable that is automatically disposed when the control leaves the scope ```cs
using (ComputeBuffer x = new ComputeBuffer(,))
{
// use x here
}

    //this to pay for the Item over the network
    [PunRPC]
    void RPC_PayForItem() {
        SaveLoad.gameData.playerMoney -= priceOfItem;
    }
``` Hey guys so I am using photon pun 2 for networking, I have been trying  so hard to figure out how to sync an int over the network so that both players see and get the same number. I want both players to have the same money basically. So when I connect to the network, everything works except this. I have watch like 10 youtube videos, read all the docs, I dont know why but I just cant understand it. As far as I know I need to use PunRPC, but running this just yields the same result for me. What key part am I missing? thanks
kindred tusk
#

Simply calling it won't invoke it (I'm pretty sure)

#

I haven't used PUN 2

# 
PhotonView photonView = PhotonView.Get(this);
photonView.RPC("ChatMessage", RpcTarget.All, "jup", "and jup.");
#

So you'll need to do something like:

PhotonView photonView = PhotonView.Get(this);
photonView.RPC(nameof(RPC_PayForItem), RpcTarget.All);
#

That will also invoke it locally so you don't need to call RPC_PayForItem directly

regal olive
#

Do I call this in start? I read this before but it confused me so much

kindred tusk
#

You call it when you want it to be called.

regal olive
#

because the example was with strings

kindred tusk
#

When you want priceOfItem to be subtracted from playerMoney

regal olive
#

So I call it inside the [PunRPC] ?

#

hold on

# 
if (Physics.Raycast(ray, out hitInfo, Mathf.Infinity, Terrain)) {
            if (Input.GetKeyDown(KeyCode.Mouse0)) {

                if (hasSpawnedPrefab == true) {
                    RPC_PayForItem();
                    hasSpawnedPrefab = false;
                    Debug.Log("Placed Object");
                }



            }
        }```
#

Do you mean call it here?

kindred tusk
#

don't do this:

RPC_PayForItem();
#

That's a direct invocation

#

Instead do this: photonView.RPC(nameof(RPC_PayForItem), RpcTarget.All);

#

Assuming you want to send it to all

#

Although the whole thing looks a bit odd...

#

Does each player have their own playerMoney?

#

If so I'd recommend putting that in your player properties

#

And not using an RPC at all

regal olive
#

Ill try it out, ive been stuck for so long. At the moment yeah, thats why I want to sync it

#

ohh

kindred tusk
#

Well if SaveLoadData is only for each player, then doesn't that mean that calling this RPC will decrement the cost from all players?

#

Do other players need to know how much money you have?

regal olive
#

Yeah i basically want to decrease it for all players

kindred tusk
#

Oh right. In that case what you have is probably fine.

regal olive
#

all player should have the same money

kindred tusk
#

Right. In that case you could put it in the room properties?

#

But this will be fine too.

regal olive
#

room properties?

kindred tusk
#

It's part of photon

#

If every player in the server shares the same pool of money you could set that as an integer in the room properties

regal olive
#

sorry im new to photon ive been ripping my hair out lol

#

My current int is actually set in a Json save file

kindred tusk
#

Anyway, when a player buys something, you can send that you want to purchase something to the master client, then they subtract that amount from the "money" room property.

regal olive
#

which is saved on every players pc

#

yeah let me test what you said real quick

#

got an error

# 
RPC method 'RPC_PayForItem()' not found on object with PhotonView 2001. Implement as non-static. Apply [PunRPC]. Components on children are not found. Return type must be void or IEnumerator (if you enable RunRpcCoroutines). RPCs are a one-way message.```

    Debug.LogError("Should not be called on non-master client");

  var nextMoney = prevMoney -= cost;
  if (nextMoney < 0) {

  changes["money"] = nextMoney;
  var expected = new HashTable();
  expected["money"] = prevMoney;
  PhotonNetwork.room.SetCustomProperties(changes, expected);
}

void BuyItem(Item item) {
  // do stuff...
  PhotonView photonView = PhotonView.Get(this);
  photonView.RPC(nameof(RPC_RequestPurchase), RpcTarget.MasterClient, item.Cost);
}
#

something like this

kindred tusk
#

I've never used photonview

regal olive
kindred tusk
#

This is how you'd do it using room properties

#

Which is appropriate for your situation

#

Basically anything that is an attribute of a player should go on player properties, anything that's shared between all players should go on the room

regal olive
#

how is the cost variable at the top set? because I dont see any changes

kindred tusk
#

When a player connects to the room they get all the current room properties, and whenever they're changed they all receive them

kindred tusk
#

So the flow is this:
player requests purchase of cost from master client -> master client checks that money is available and updates shared money -> updated shared money amount is propagated back to clients.

# 
void OnRoomPropertiesUpdated(Hashtable propertiesThatChanged) {
  if (propertiesThatChanged.ContainsKey("money")) {
    Debug.Log("We now have $" + propertiesThatChanged["money"]);
  }
}
#

Something like that

regal olive
#

Yeah im just trying to process it all

kindred tusk
#

It's a bit of a fuckaround, but you can generalise this stuff

regal olive
#

my brain is exploding right now

kindred tusk
#

Multiplayer is hard

regal olive
#

Yeah ive tried it many times before and failed

#

but ive actually got it working this time, except this one part to sync variables

kindred tusk
#

Yeah so room properties auto-sync between clients. They just have their own way of working

#

So room.SetCustomProperties to set -> OnRoomPropertiesUpdated to listen for changes

#

And the master client should be responsible for changing them

#

So you need to notify the master client that it needs to be done

#

But they will be synced

regal olive
#

Yeah i think I get it in theory a little bit anyway

kindred tusk
#

You can also sync stuff like current game state through these

#

For example whether the game has started

#

Each player adds "ready: true" to their player properties

#

And when the master client sees that everyone has done this it sets "isGameRunning: true" in the room properties

#

When clients see that they all load teh game scene

#

They can also set the level there so they know which scene to load

#

It's pretty robust in my experience

regal olive
#

Yeah, If I can get it working, ill probably end up using it for so many things

kindred tusk
#

Yeah, you can write helpers for it

#

Doesn't need to be this verbose

#

Anyway, good luck. Hope it helped point you in the right direction.

#

Kinda busy with some work but if you get absolutely stuck you can DM me

Might be slow to respond

the room settings I havent messed arround with but after some testing with this CS PhotonView photonView = PhotonView.Get(this); photonView.RPC(nameof(RPC_TesMod), RpcTarget.All); I managed to fix the error.

#

Ok so in your fragment shader you'll get the vector from the current pixel to the center in uv space, the current pixel will be between (0 0) and (1 1)
The center is (.5 .5)

#

Use magnitude to check the length, discard magnitudes over 0.5

#

Use atan2 to get the angle and discard angles you dont want

#

If you dont want a sharp pixel edge you can simply modulate the alpha when near the limits

#

The built in quad in unity should already have the correct uvs so all you need is to change the shader to your own

Just tryna understand/resolve this issue: So in the above, I have coroutines that I want to complete [CloseSwitchBoard triggers other coroutines], but each has the coroutineRunning check. Is there a way to have the loop completed then everything else below,

alright, so- I need my camera to scale to the correct ratio for visibilitys sake [ie adding a black bar top/bottom/left/right or stretching depending on the situation]
so that everything will be scaled correctly regardless of the screens aspect ratio.
I have already found a script that does this beautifully.. for one camera.
problem is I don't have just one camera.. I have two. the 2nd one is for a minimap thing.
and I can't figure how I would keep the minimap in the same [relative] space at the same [relative] size to the other camera on screen.
ie; regardless of the window size, it would be made to fit like so:

Hello, I've made this diagram for my problem but I'm stuck because I don't know if I have to use a design pattern, or use abstract classes or use interfaces. I've read many many articles and documents, but I can't seem to find which way to do it the best. If someone can advise me to the good way I would appreciate it, thanks in advance

Given your diagram both interfaces and abstract classes can be used for BusinessFolder and BusinessWorkbook.
So it all comes down to what is inside of them. If you need an implementation (virtual methods, private fields with a constructor to init these fields), then use an abstract class. Otherwise use an interface.

raven rock
#

Thank you for your answer sir, do you think it's worth it to use a factory design pattern considering I'll have more BusinessFolders and BusinessWorkbooks in the future ?

plucky laurel
#

what should that accomplish

fresh salmon
#

Factories can ease out the creation and initialization of objects, so why not. Could also use generics in the factory class, something like public static T Create<T>() where T : new(), BusinessFolder for example

#

So you can do FolderA a = FolderFactory.Create<FolderA>()

#

What I'm slightly concerned about is for these concrete implementations, if they aren't different in any way compared to the base class, then use instances. So the two "base classes" are not abstract anymore, and you create several instances of them

unknown.png
#

But again, it comes down to what data is in these classes, and this isn't specified in that diagram

raven rock
#

I'm trying to automatize my task at work.
We open a folder named for this example FolderA.
FolderA must always contain WorkbookA and WorkbookB (WorkbookA is different than WorkbookB).
Then I have to open each workbook and control values inside it.
That's why I created a base Folder class, and I inherit my folders from it but each folder must have different workbooks inside it. I have to add a method to control the validity of the folder (if it really contains both workbooks) and if yes I have to make a method to control the validity of each workbook by telling for example that cell range "C3" must contains a number value

#

I don't know if it's more understandable ^^

fresh salmon
#

By "we open a folder" you mean a logical folder on your hard drive? Or is it a type from another software?
I also fail to see how this is related to Unity for now...

raven rock
fresh salmon
#

Okay, so that logical folder contains "workbooks", what are those, files?

raven rock
#

yes .xlsx files

#

I use syncfusion Xls Io to manipulate them

fresh salmon
#

Ah alright. I start to see an architecture here, that could be converted to C# types

#

It would actually be just one type, not abstract nor static, BusinessFolder, that contains the path to the folder, the name of the folder (can be determined with a computed property and an IO call), and an instance of Workbook whatever SyncFusion calls it.

Then, you would have an interface, IFolderValidator that declares a void Validate(BusinessFolder folder, ReportContext ctx) (where ReportContext is a utility to report errors to the user via dependency-injection).
And multiple concrete implementations of IFolderValidator, depending on what to validate in those workbooks. Say the sheet count, then make a class SheetCountValidator : IFolderValidator and check for that in its implemented Validate method.

Pseudo-code of the validator runner:

List<BusinessFolder> folders = // ...
List<IFolderValidator> validators = // declare validators here

// somewhere else
foreach (BusinessFolder folder in folders) {
  ReportContext ctx = new();
  foreach (IFolderValidator validator in validators) {
    validator.Validate(folder, ctx);
  }

  foreach (Error e in ctx.Errors)
    // Print error or whatever
}
raven rock
#

Wow I've understood, I didn't think to make the validity logic an interface, I was just creating methods and I felt overwhelmed by all the code, thank you again I'm going to try rn 🙂

Has anyone reverse engineered asset store API calls [0] in order to download asset store assets in a CI/CD system? I'm doing it now because 1 I want my code to be public (for public consumption and for github pages) 2 I use github actions as my CI/CD system (automated testing and building for unity projects FTW!!) and 3 I **legally **can't nor want to (portability reasons) version control assets from the asset store (even if they are free!). What a pickle 🥒

Fortunately, if I can write an editor script in C# that can download and import packages for my project then I can add that to my build process [1]. Unfortunately, unity hasn't provided a scriptable API for the asset store and thus I must reverse engineer the RESTful interactions from unity's decompiled code (see [0]). There are a lot of collaborating classes to make the REST calls so it's a bit of slow going to piece it together.

So far I've figured out a call to get a valid login form

curl -vL https://assetstore.unity.com/auth/login

The next step is to write the C# script version of this curl command, log in, and store my session data. Then I can reverse engineer the REST calls to download and then import the downloaded .unitypackage files into my project.

Anyways I figured I would reach out here for some help. I am very interested in any sort of advice. I would be thrilled if this is an exercise someone else has already done the work on. At the very least, if I'm the first guy doing the work then I might as well build a CLI tool and a (series of) blog(s) to help others in a similar situation.

#

P.S: how I've been avoiding this issue in the past is just authoring my own sound, music, and 3d model assets (which I then own the copyright for by default) and then version controlling those assets. For global game jam, I really really want to leverage free assets from the asset store >.<

Just in case it hasn't occurred to you, have you considered hijacking UPM instead? It might be less effort

#

well, you have the source to package manager. All of that is accessible to you with reflection. So if you can figure out what it does in the UI, you can just make it do whatever it does for downloads with your own script

regal olive
regal olive
#

...Right?

pseudo crown
#

If the package manager API to download asset store packages isn't public and supported, you might be safer reverse engineering the REST API. Unity defined their REST contract and won't change it lightly because it might break multiple tools and processes. If you use the internal package manager API you could still be affected by REST API changes on top of changes to only the package manager API, so I don't think it will be worth it (unless things have changed in the last year and they have public C# calls available now).

Anyone experienced with procedural normal maps?

#

cant find any proper documentation

#

I cant seem to use normals facing in all directions, and I assume that is related to tangents

#

its a simple triangle with uvs (0.5f, 0), (0, triHeight), (1, triHeight)
I have normals in object space I wanna put on the texture but not sure what kind of transformation i need to put them through

#

because of those UVS and my very limited understanding of tangents, i assume the tangent would be tris[2]-tris[1]

# 
Color normalColor = new Color() {
                    r = objectSpaceNormal.x * 0.5f + 0.5f,
                    g = objectSpaceNormal.y * 0.5f + 0.5f,
                    b = objectSpaceNormal.z * 0.5f + 0.5f,
                };

This is what I am doing and it clearly doesnt work correctly, the normals are mirrored across the z plane

I want to serialize a List of Transform values (position, rotation, scale). I want to be able to deserialize the data and reconstruct the values. Is there a go-to-solution or should I write my own Serializer. If the latter: Should I round the floating numbers to the 5th decimal digit since this will be "close enough" for reconstruction?

I tried a "i have no idea what i'm doing" approach: ```
Vector3 tangentSpaceNormal = new Vector3(
Vector3.Dot(objectSpaceNormal, tangent),
Vector3.Dot(objectSpaceNormal, bitangent),
Vector3.Dot(objectSpaceNormal, normal)
).normalized;

which provides light coming from roughly the correct direction, but its not quite accurate..

// Texture settings
Texture2D normalTexture = new Texture2D(texSize, texSize, TextureFormat.RGBA32, false, true);
        normalTexture.filterMode = FilterMode.Trilinear;

...

// Normal conversion
Vector3 tangentSpaceNormal = new Vector3(
                    Vector3.Dot(objectSpaceNormal, tangent),
                    Vector3.Dot(objectSpaceNormal, bitangent),
                    Vector3.Dot(objectSpaceNormal, normal)
                ).normalized;

                Color normalColor = new Color(
                    tangentSpaceNormal.x * 0.5f + 0.5f,
                    tangentSpaceNormal.y * 0.5f + 0.5f,
                    1,
                    1
                );
                normalPix[i] = normalColor;
#

its very close to being correct now, its just that theres noticable edges between the different lit triangles (every triangle is its own mesh btw), shadows don't quiite line up and the shadow line isn't rounded. the normals are a perfect sphere so I dont expect the shadow lines to be perfectly straight in each triangle.

If i use an unlit shader and simply draw the object/world space normals to the texture, theres no seams. So its something wrong with either my tangents/conversion or the shader (standard shader).

And to reiterate, every triangle is its own mesh.

Hey guys can anyone know the reason that is it normal or not ? I created a command pattern based rewind system I am recording all that transform translate commands in update then rewinding but when i start with Vector3.zero position it not returns 0-0-0 but other values are working

#

Instead of coming to zero, it is stuck at a value such as epsilon, which is very close to zero.

transform movement Comamand working like this

sly grove
#

yeah Translate does arithmetic

#

I'd say store a history of the actual positions and just restore that position directly, rather than translating in the opposite direction

short junco
#

but i will extend all of these action in future I want to rigidbody based physic rewind but in that scenerio just keeping pos,rot of rigidbody will work ?

sly grove
#

e.g. instead of undoDir = -dir; just save undoPos = obj.position;

#

and to undo do obj.position = undoPos;

sly grove
#

it will work fine

#

You will also need to save the velocity and angularVelocity of the Rigidbody though

short junco
#

yeah tons of data 😄

sly grove
#

also it will be more precise to save obj.localPosition and obj.localRotation

#

rather than position and rotation

short junco
#

I'll note this right away thanks a lot 🙂

#

@sly grove I also forget the ask some physic question imagine we are goind A to B then a static object will appear between A-B and thats not rewindable when i rewind with phsyic rigidbody will not understand there is a new object in this situation what would u suggest ? creating a new physic scene and calculate every undo action with that scene returnable velocity ? or anything else 😄

When using FindObjectsOfType<> it gets every component of that type from the scene. Is there a way I can get the objects these components are attached to instead?

you can just use the json itself as one piece of data

your value becomes something like

{
position: "10,5,6",
rotation: "10,20,0,0",
scale: "1,1,1"
}

it doesn't matter how exactly the values are serialized, as long as you are consistent between serializing and deserializing stuff then it should all be ok.

also more human readable in case you ever need to look at the values

I disagree (politely). My problem boils down to the technology (unity) doesn't support what I'm trying to do. Primary question: why isn't there an asset store scriptable API like there is for everything else?

Hey guys, I'm at a bit of a loss here. If anyone could point me to the right direction I'd appreciate it!
I have a save/load system on my platformer game that uses a binary formatter. I want to be able to save a few things(puzzle state etc), including the player position, on a checkpoint at the end of each level. I currently do this by having a collider at the end of each level that:
1 - Saves the player checkpoint position to a list
2 - Adds a series of listeners(i think that's the correct term?) to events that are described in the inspector, most being related to saving the puzzle state
3 - Invokes an action on the main saving script that calls those listeners, adds their information to the list, then formats that list into binary and commits it to the hard drive.
4 - Invokes another action to remove the listeners
It works fine, but the game briefly freezes every time the script runs. This is obviously not okay, and kind of ruins the experience. I SUSPECT the issue is that I'm using [ActionName]?.Invoke() in the main saving script, instead of something asynchronous like BeginInvoke(). But I'm but a humble unity programmer and I know nothing about the more complicated C# stuff. I have no idea how to implement that, and if that's even the issue. As you can see on the screenshot, I do need the "continuity" that invoke provides so that I can commit the files after all actions are done, and then remove all listeners. I suppose the "callback" argument on BeginInvoke has something to do with this? Again I'm a total noob at these stuff XD
Any help is appreciated. Sorry if I interrupted any other conversation.

A large percentage of the free assets on the asset store are samples, they are not intended to just be passed around for free, they are intended to get you interested in their assets and buy them. Without the context of the asset store, this doesn't work as well. Therefore theres very little incentive to allow you to pull the free assets in an automated fashion.

They put it up under unitys license, theres other sources that may fit your use case better. For example opengameart
But that's the thing... I don't want to have to version control 3rd party assets in order for my CI/CD system to build. It's... so clunky. Other languages utilize package managers (like npm in the node ecosystem) so you don't have to version control 3rd party code. There has to be a better way

Therefore theres very little incentive to allow you to pull the free assets in an automated fashion.
I follow this logic. Where it breaks, though, is when I then talk about importing my paid assets from the asset store from a CI/CD context. There still isn't a scriptable API for the asset store where I can identify myself and download assets I've paid for.

There's the problem. It's like Unity hasn't considered the CI/CD use case. So how do people build their unity software using paid assets?

Well, most do it by going against the asset store EULA and version controlling assets from the asset store. This works if your repo is private, at least until GitHub allows DMCAs against private repos.

Obviously I get around this by just creating my own assets (which I then own the copyright to by default) and then I get to decide what can go where... But that is just not leveraging the asset store, lol.

Hi everyone, is it possible to have custom animation playables that have run on it’s own time when the timeline speed is 0? I’m trying to sequence dialogues and animations together but during dialogues pauses the animations are pauses as well.

How does Unity make functions like Update() Awake() OnCollisionEnter() etc.. work? Is there a way were I can do this myself, to have classes inherit from a base class that allows all inherited classes to "use" the function instead of using overwrite

Okay, this's pissing me off. I'm trying to drop a monoscript onto a scriptable object to make an object.
I want to make an instance of a derived class and not the base class, but it's making me the base class. How can I make it more variable than it is now?

What I'm not getting from the inspector for the SO is the enum, just the float.

# hallow cove During runtime

I suppose you'd have to first see if you can use a model outside of the project build during runtime. If so, the rest is just downloading a file and placing it in the right location on your device. for the first step, you'd have to check the restrictions on which directory can you pull models from on runtime. If the resource folder is accessible to download files to, you could start with that.

fresh salmon
#

Yeah exactly, before jumping into the networking part, see if you can load a mesh that is stored on your filesystem first

#

Once you are able to, switching to the net download isn't hard, given that what's on your filesystem and what you're downloading has the same format

since the property you are serializing is a Effects and not the derived class, unity is creating the editor ui based on that base class

#

The inspector can't show you information isn't privy to. So if you don't include the subclass, how can it know the enum?

torn geode
hybrid ravine
#

you can probably use reflection to just get your extra properties not to have to make one for each

torn geode
torn geode
hybrid ravine
compact ingot
hybrid ravine
#

you simply take the System.Type of your subclass and get the properties and fields
go through those to take the public and/or serialized ones to then display them on your editor
that will return you FieldInfo or PropertyInfo types which contain all the information about the field/property
both of those have SetValue and GetValue methods you can use to get/set the values of the instance (which you must give in as a parameter)

#

you can easily loop those to then create a ui based on the type of each field/prop and call the get set values accordingly

#

If you get stuck, let me know and I can help you out with it

torn geode
hybrid ravine
#

I can send you what I made to get all the fields and properties to dynamically create and handle sql tables

torn geode
#

Go for it.

#

And maybe an example of the customUI route, if it’s more efficient.

hybrid ravine
#

Essentially, you start by a method to get all those fields and props

#

The GetSetMember is a class I made to keep the props and fields in the same list since they don't both derive a class with the get set methods. you can replace it with FieldInfo or PropertyInfo depending on what you are using or make your own to do the same

private GetSetMember[] LoadSerializableFields(Type self)
            {
                const BindingFlags bindingFlags = BindingFlags.Public | BindingFlags.Instance;

                List<MemberInfo> members = new List<MemberInfo>(self.GetFields(bindingFlags));
                members.AddRange(self.GetProperties(bindingFlags));

                List<GetSetMember> serialized = new List<GetSetMember>();

                for (int i = 0; i < members.Count; i++)
                {
                    GetSetMember member = members[i];
                    if (member.Name == "Id" || member.IsNotSerializable) continue;
                    Type type = member.ValueType;
                    if (type.IsPrimitive || type == typeof(string) || type == typeof(DateTime)) serialized.Add(member);
                }

                return serialized.ToArray();
            }```
#

in the loop, I don't keep the field with the Id name since in this example I am getting the fields for the sql table and already have it elsewhere so you can ignore that too

▶ Play video
#

But, you can't use List, Dictionary any of that good stuff. You're limited to using Unity.Collections which are thread safe version of the generics

#

but they are super limited in return for being much faster and able to run on many threads/cpu cores

#

You also can't touch any MonoBehavior classes or static classes/variables

hybrid ravine
#

this guy just changed the int to var in his for loop, call the cops

#

okay, I watched your video but I am still not sure what you are tying to do

charred tangle
#

lol I mean I had no other choice

#

basically

#

I want to access a Dictionary<int, MyStruct> here within a job

#

but it won't allow for that, it only allows primitive or "blittable" types

strong garnet
#

Could you define a NativeHashMap<int, MyStruct> outside the job and use that everywhere instead?

#

Or does something depend specifically on Dictionary

#

(disposing of the NativeHashMap when it's time of course)

hybrid ravine
#

yeah, sounds like they have various alternative that you have to use

charred tangle
#

I can't really even define that, since it NativeHashMap won't allow the struct datatype. I also can't access any outside classes, because it wont allow me to reference classes within the struct x.x

#

yeah, really sucks tbh. would be nice to just be able to call stuff normally

hybrid ravine
#

maybe they'd know more

strong garnet
#

To provide the best answer I can with the info here, it might be worth revisiting what you have laid out to see if it might be possible+worth refactoring some stuff in light of better knowledge of how you're going to need to interface it with jobs

#

e.g. if there are any classes that would be better off as structs, etc.

see how theres less options?

some disappear?

how do i make my own classes have that? where some variables disappear if another is different?

hybrid ravine
#

you make a Custom Editor

hasty tinsel
#

what exactly does that mean/entail

hybrid ravine
#

it means you create a new class that handles drawing those thignies

so you can create extra boolean ui element that, when selected or not selected, change whether you draw x or y

what does your struct look like? does it have any non blittable types?

charred tangle
#

The only thing that might be non-blittable is this

#

I was under the false impression that Vector2, Vector2Int couldnt be used so I was using int2 instead

#

That might be the cause

sly grove
#

Nullable types are definitely not blittable

austere jewel
#

Can you have nullable types? I've not thought about that before

charred tangle
#

I see

#

that might be why

austere jewel
#

Also, there's a bool and a class in there?

charred tangle
#

Those are also structs

#

bools are non-blittable? wow

austere jewel
#

MultiCellUnitData looks like a class at a glance, but I'm not that familiar with VS' colour schemes

it would explain why it's underlining the nullable too

Let me remove the nullable types, then and try again

I don't know what "lts 1.2 means", but it should be available

#

I've also seen a warning on SmtpClient that it shouldn't be used anymore because it doesn't accept any new protocols. Using a NuGet package is recommended

plush lion
#

Right so here's a context: I'm working on a legacy app cause for a few months the send mail feature stopped working on Android. Logcat tells me it's an smtp error, and sends me a link to an article saying that office 365 (the mail service we use) will no longer be supporting lts 1.0 and 1.1. So I'm thinking ok well I'll just look up what version of .net uses lts 1.2 but according to what you say we should already be using it.

@fresh salmon do you know if there's a way to check what version of .net I currently uses actually? Best I have is .net 4.x

Hey Guys, i have the following Problem.
I have Canvas for my Tutorial with an Arrow Element. I now just want to define on which element the arrow should point (The Element could be everything, Overlay Canvas UI Element, ScreenSpace Canvas UI Element, World Space element (3d Object and also worldspace ui). What is the best way to calculate the correct position for the arrow in all these cases. I also want to point the arrow for example on the top border of an element so it would be nice I somehow get the correct borders of the element the arrow should point to

#

Any Ideas?

plush lion
#

Lmao fitting username

regal olive
plush lion
#

So a simple way to do it would be to have a canvas on your camera, and project the position you wanna point to on the canvas plane. That's where your arrow should point

#

If it's an ui element the projection doesn't change anything, and if it's a 3d object it'll project onto the correct position

#

I think there is a Vector3.projectonplane or something

regal olive
plush lion
#

Yeah, all you need is the transform of the object you point to

regal olive
#

The Plane would just be the ScreenSize, am i right ?

plush lion
#

The plane in here is a theorical infinite plane that doesn't actually exists in your code

regal olive
#

plane = new Vector3(Screen.width, Screen.height, 0f);
response = Vector3.ProjectOnPlane(targetTransform.position, plane);

#

Is this how the code would look like?

#

Or am i wrong in my thinking

#

?

plush lion
#

No, you describe a plane using its normal. Here, the normal would be Camera.main.transform.forward

regal olive
#

Interesting, i will try that, thanks

plush lion
#

You should look up a bit of linear algebra, it really helps with these kinds of situations.

You can try with sqrMagnitude instead (that doesn't contain any square roots), and see if it improves performance:

if ((unscaled_p_viewer - unscaled_p_chunk).sqrMagnitude < radius * radius)

You of course have to take the differences in consideration, so that's why we square the radius

How are you profiling that? Stopwatch, and inside the editor? Bad idea, it doesn't take in account the CPU overhead and all the low-level complicated stuff.
If you need to measure performance, use a build and the Unity Profiler

Is it considered bad practice/bad idea to 'wrap' a singleton in statics?

public static void DoSomething(string foo)
{
  Instance.DoAThing(foo);
}

// Called as
BarClass.DoSomething("");
// vs
BarClass.Instance.DoAThing("");
#

In my case it is a MonoBehaviour, so to add on to this, what about having a separate normal static C# class that calls the singleton methods/properties as this would remove all of the noisy of the UnityEngine.Object static methods.

fresh salmon
#

I wouldn't consider it bad practice, but if that's just to "proxy" the instance methods with nothing else, I don't really see the use of it. Plus, it doubles the number of lines in your class. If you still want that, but want to lighten up the code, look into partial classes

cedar saddle
#

or is it just so you can define the functions separately?

fresh salmon
#

One part that contains all of the instance stuff, and the other that contains the proxies

urban warren
fresh salmon
#

Oh you're doing an API, then yeah definitely make it easy for the user

urban warren
#

Yeah sorry I should have been clearer. So having a separate class that is just a static proxy for the singleton is fine/good idea?
