[1.11] Set UV values for a custom particle

[MSpace-Dev]

I have created a custom particle using textures from a 128x128 PNG file. Basically, exactly like Vanilla MC does. The reason I want to do this is because I don't want to register new particle textures for each particle I want to add.

 

So, all I want to do is set the UV that the particle uses for its texture.

 

public class ModParticle extends Particle {
    public ModParticle(World worldIn, double xCoordIn, double yCoordIn, double zCoordIn, double xSpeedIn, double ySpeedIn, double zSpeedIn) {
        super(worldIn, xCoordIn, yCoordIn, zCoordIn, xSpeedIn, ySpeedIn, zSpeedIn);
        this.particleRed = 1;
        this.particleGreen = 1;
        this.particleBlue = 1;
        this.particleMaxAge = 100;
        this.setParticleTexture(RegistryEventHandler.textureAtlasSprite);
    }

    @Override
    public int getFXLayer() {
        return 1;
    }
}

 

Thanks!

I have found buffer.tex(double u, double v), except when I call that method in renderParticle, nothing changes. I have looked through the Minecraft Particle classes to see if they've set UVs anywhere, couldn't find anything similar, heck, some of them don't even have a renderParticle method in them. So I'm guessing their UV is set somewhere else all together.

 

Can't find anything close to buffer.tex(u, v).

 

@Override
    public void renderParticle(VertexBuffer buffer, Entity entityIn, float partialTicks, float rotationX, float rotationZ, float rotationYZ, float rotationXY, float rotationXZ) {
	buffer.tex(8, 8);
        super.renderParticle(buffer, entityIn, partialTicks, rotationX, rotationZ, rotationYZ, rotationXY, rotationXZ);
    }

Oh, is that what you mean. Alright, thanks. Gonna get cracking on then.

@diesieben07 Anyway I can get the size of the entire Minecraft atlas that is created at runtime? I need this value to work out the UV coords of my texture.

[MSpace-Dev]

Well, if I set the Max, min UV to 0 and 1, the particle turns into the entire MC atlas, right. So, using the minU, and minV values, and using the full size of Minecraft's texture atlas, I will be able to set the appropriate UV percentage values for my particle.

Yeah, I know that already. Hang on... An idea just popped into my head. Let me see if it'll work out.
