[Solved][1.10.2] TextureAtlasSprite for custom particle coming back null

[Codasylph]

I'm going to preface this by saying that, no, I have never used TextureAtlasSprites.

 

I'm trying to make a custom particle and through my reading of the vanilla Particle code and looking at other people's projects, I've gotten as far as, that I need a TextureAtlasSprite, and that I ought to register it to the TextureMap in TextureStitchEvent.Pre (or at least that's what all the code I've seen is doing.) However, when I do all this and try to retrieve my sprite from the TextureMap I get the missing texture texture, and if I try to use it more directly I get null.

 

My event handler registering the sprite

public class DemTextureHandler 
{
public static final DemTextureHandler textures = new DemTextureHandler();

private DemTextureHandler(){}

public static TextureAtlasSprite su;

@SubscribeEvent
public void onTextureStitch(TextureStitchEvent.Pre event)
{
	ResourceLocation resource = new ResourceLocation("demesne:textures/particles/su.png");

	TextureAtlasSprite su = event.getMap().registerSprite(resource);
	System.out.println("Debug: "+su.toString());
	System.out.println("Debug: "+event.getMap().getAtlasSprite(resource.toString()));
}
}

Note: my debug statements here give me the following in the log:

[08:26:29] [Client thread/INFO] [sTDOUT]: [me.codasylph.demesne.handlers.DemTextureHandler:onTextureStitch:25]: Debug: TextureAtlasSprite{name='demesne:textures/particles/su.png', frameCount=0, rotated=false, x=0, y=0, height=0, width=0, u0=0.0, u1=0.0, v0=0.0, v1=0.0}
[08:26:29] [Client thread/INFO] [sTDOUT]: [me.codasylph.demesne.handlers.DemTextureHandler:onTextureStitch:26]: Debug: TextureAtlasSprite{name='missingno', frameCount=1, rotated=false, x=0, y=0, height=16, width=16, u0=0.0, u1=0.0, v0=0.0, v1=0.0}

 

my particle's constructor

public SuParticle(World world, double xCoord, double yCoord, double zCoord, double xSpeed, double ySpeed, double zSpeed)
    {
    	super(world, xCoord, yCoord, zCoord, xSpeed, ySpeed, zSpeed);

//    	this.setParticleTexture(DemTextureHandler.textures.su);
    	this.setParticleTexture(Minecraft.getMinecraft().getTextureMapBlocks().getAtlasSprite("demesne:textures/particles/su.png"));
    	System.out.println("Debug: "+this.particleTexture.toString());
    }

As you can see from commented out code I have also tried using the sprite that gets returned by TextureMap#registerSprite but this ends up being null and when my debug statement is called I crash with a null pointer exception, which kind of makes sense since it clearly isn't registering properly given that it can't find the texture in the map even immediately after I register it..

 

So clearly I'm doing something very wrong.  I have checked the spelling of my path what feels like a 100 times and I for certain have a folder in my textures folder named particles that has a su.png in it.

 

If anyone knows what is happening here and how to fix it, or some better way to do this, please help.

 

edit: Added version tag to subject line.  Someday I will remember to do this the first time.

Hi

 

I think you should remove the .png from your filename.

 

Have you seen this tutorial project yet?

https://github.com/TheGreyGhost/MinecraftByExample

mbe50 has a simple working example of what you need.

 

Also, I have a recollection that getAtlasSprite won't retrieve the texture until after the textures are stitched, so your getAtlasSprite immediately after registerSprite is too soon (i.e. it's not testing what you think it's testing).

I think you should remove the .png from your filename.

 

That actually fixed, I had to also remove the "textures/" from the beginning as well. I could have sworn I had tried that, but I may not have tried both changes together.

 

Any idea why for the texture atlas you need the short form (e.g. "demesne:particles/su" but when you bind a texture to the texture manager for a gui it has to be the longer version with the file extension?

 

Either way, thank you very much!

The ResourceLocation class adds the /texture and .png for you.

The ResourceLocation class adds the /texture and .png for you.

 

It's actually

TextureMap#getResourceLocation

that adds the prefix and extension to your

ResourceLocation

before loading the texture.

 

ResourceLocation

is used for many things that aren't textures, so it wouldn't make much sense if it added the prefix and file extension automatically.
