Trying to add a new particle, and it does retrieve the texture, though when I try to add the particle it does not render.

 

Particle

Spoiler

public class LightParticle extends SpriteTexturedParticle {
    private IAnimatedSprite spriteOther;

    protected LightParticle(World worldIn, double x, double y, double z, IAnimatedSprite sprite) {
        super(worldIn, y, x, z, 0, 0, 0);
        this.spriteOther = sprite;
        this.particleScale *= 2.0F;
        this.maxAge = 100;
        this.setSprite(sprite.get(0, 1));
    }

    @Override
    public IParticleRenderType getRenderType() {
        return IParticleRenderType.PARTICLE_SHEET_TRANSLUCENT;
    }

    @Override
    public void tick() {
        if (this.age++ > this.maxAge) {
            this.setExpired();
        } else {
//            this.particleAngle += this.age;
        }
    }

    public static class Factory implements IParticleFactory<BasicParticleType> {
        private final IAnimatedSprite sprite;
        
        public Factory(IAnimatedSprite sprite) {
            this.sprite = sprite;
        }

        @Override
        public Particle makeParticle(BasicParticleType typeIn, World worldIn, double x, double y, double z, double xSpeed, double ySpeed, double zSpeed) {
            return new LightParticle(worldIn, x, y, z, this.sprite);
        }
        
    }
}

 

Registry

Spoiler

@Mod(RadiantMagic.MODID)
public class RadiantMagic {

...

@EventBusSubscriber(modid=MODID, bus=Bus.MOD)
    public static class RegistryEvents {

...

public static final BasicParticleType lightParticle = new BasicParticleType(false);

...

@SubscribeEvent
public static void onRegisterParticles(final RegistryEvent.Register<ParticleType<?>> event) {
     lightParticle.setRegistryName(new ResourceLocation(MODID, "light_particle"));
     event.getRegistry().register(lightParticle);
 }
        
 @SubscribeEvent
 public static void onRegisterParticleFactory(final ParticleFactoryRegisterEvent event) {
       Minecraft.getInstance().particles.registerFactory(lightParticle, sprite -> new LightParticle.Factory(sprite));
 }

}

}

 

LightSourceBlock

Spoiler

@OnlyIn(Dist.CLIENT)
	@Override
	public void animateTick(BlockState stateIn, World worldIn, BlockPos pos, Random rand) {
		if (holdingItem()) {
			worldIn.addParticle(RadiantMagic.RegistryEvents.lightParticle, pos.getX() + 0.5, pos.getY() + 0.5, pos.getZ() + 0.5, 0, 0, 0);
		}
		super.animateTick(stateIn, worldIn, pos, rand);
	}

 

 

Hi

What are the symptoms, specifically?

 

YOu might find this tutorial project useful, it has a working example of Particles (vanilla and custom)

I'm not really sure what the "symptoms" are, there aren't any errors, and looking at the particle sprite data, it does seem to find the correct texture file. Putting a print statement in the tick method of the particle shows that it does run, though nothing appears in-game. Perhaps the uv coordinates are incorrect, I'm not sure. Here's the sprite data: 

TextureAtlasSprite{name='radiantmagic:particle/light_particle', frameCount=1, x=224, y=96, height=16, width=16, u0=0.875, u1=0.9375, v0=0.375, v1=0.4375}

Rendering is difficult to debug because there are many different ways it can go wrong without any specific symptoms.  Taking baby steps is the best way to troubleshoot it, in my experience.

 

If you post your code on GitHub I can take a look if you like.
