A few days ago I asked on this forum how to make a custom particle. Now I am have trouble with it. Am I supposed to register the particle somehow? How do I spawn my custom particle in the world?

 

Here is my code thus far:

 

Particle code:

public class ParticleSteam extends Particle {
    protected ParticleSteam(World world, double posX, double posY, double posZ, double speedX, double speedY, double speedZ) {
        super(world, posX, posY, posZ, speedX, speedY, speedZ);
    }

    @SideOnly(Side.CLIENT)
    public static class Factory implements IParticleFactory
    {
        public Particle createParticle(int particleID, World world, double xCoord, double yCoord, double zCoord, double xSpeed, double ySpeed, double zSpeed, int... p_178902_15_)
        {
            return new ParticleSteam(world, xCoord, yCoord, zCoord, xSpeed, ySpeed, zSpeed);
        }
    }
}

Never worked with Particles, but I have seen the ParticleManager and it has a registry function.

Ok, thanks. I'll try that.

I'm getting a crash because of a nullpointer. I've seen so many crash reports today, lol.

 

Main class where I register the particle:

public class RobotiCraft
{
    public static final String ModId = "roboticraft";
    public static final String Name = "RobotiCraft";
    public static final String Version = "1.11R1.0.0";
    // static final String Dependencies = "required-after:" + "owlcore" + "@[" + Version +  ");";

    public static Logger log = LogManager.getLogger(ModId);

    @Mod.Instance
    public static RobotiCraft instance = new RobotiCraft();

    @SidedProxy(clientSide="wiseowl5.roboticraft.Proxies.ClientProxy", serverSide="wiseowl5.roboticraft.Proxies.CommonProxy")
    public static CommonProxy proxy;

    public static CreativeTabs creativeTab = new ModCreativeTab();

    public static int steamParticleID = 49;

    @EventHandler
    public void preInit(FMLPreInitializationEvent e) {
        //Read config file, create blocks/items and register them
        Minecraft.getMinecraft().effectRenderer.registerParticle(steamParticleID, new ParticleSteam.Factory()); //Crash report points here

        ModFluids.initFluids();

        ModItems.initItems();
        ModBlocks.initBlocks();

        GameRegistry.registerWorldGenerator(new ModWorldGen(), 3);
    }

    @EventHandler
    public void init(FMLInitializationEvent e) {
        //build data structures, add new handlers
        ModRecipes.initRecipes();

        proxy.registerGuiHandler();
    }

    @EventHandler
    public void postInit(FMLPostInitializationEvent e) {
        //Communicate with other mods
    }
}

I'm going to say that Minecraft#effectRenderer is not initialized when you are calling the registerParticle method. Try some other ones like init or postInit.

Ok, will do.

 

On another topic, does the edit button for editing your posts show up for you anymore? I think they are changing stuff again.
