[1.11] Register Particles


Recommended Posts

Posted (edited)

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);
        }
    }
}

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.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

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.

    • Hi, i'm really having problems trying to set the texture to my custom item. I thought i'm doing everything correctly, but all i see is the missing texture block for my item. I am trying this for over a week now and getting really frustrated. The only time i could make the texture work, was when i used an older Forge version (52.0.1) for Minecraft (1.21.4). Was there a fundamental change for textures and models somewhere between versions that i'm missing? I started with Forge 54.1.0 and had this problem, so in my frustration i tried many things: Upgrading to Forge 54.1.1, created multiple new projects, workspaces, redownloaded everything and setting things up multiple times, as it was suggested in an older thread. Therea are no errors in the console logs, but maybe i'm blind, so i pasted the console logs to pastebin anyway: https://pastebin.com/zAM8RiUN The only time i see an error is when i change the models JSON file to an incorrect JSON which makes sense and that suggests to me it is actually reading the JSON file.   I set the github repository to public, i would be so thankful if anyone could take a look and tell me what i did wrong: https://github.com/xLorkin/teleport_pug_forge   As a note: i'm pretty new to modding, this is my first mod ever. But i'm used to programming. I had some up and downs, but through reading the documentation, using google and experimenting, i could solve all other problems. I only started modding for Minecraft because my son is such a big fan and wanted this mod.
    • Please read the FAQ (link in orange bar at top of page), and post logs as described there.
    • Hello fellow Minecrafters! I recently returned to Minecraft and realized I needed a wiki that displays basic information easily and had great user navigation. That’s why I decided to build: MinecraftSearch — a site by a Minecraft fan, for Minecraft fans. Key Features So Far Straight-to-the-Point Info: No extra fluff; just the essentials on items, mobs, recipes, loot and more. Clean & Intuitive Layout: Easy navigation so you spend less time scrolling and more time playing. Optimized Search: Search for anything—items, mobs, blocks—and get results instantly. What I’m Thinking of Adding More data/information: Catch chances for fishing rod, traveling villager trades, biomes info and a lot more. The website is still under development and need a lot more data added. Community Contributions: Potential for user-uploaded tips for items/mobs/blocks in the future. Feature Requests Welcome: Your ideas could shape how the wiki evolves! You can see my roadmap at the About page https://minecraftsearch.com/about I’d love for you to check out MinecraftSearch and see if it helps you find the info you need faster. Feedback is crucial—I want to develop this further based on what the community needs most, so please let me know what you think. Thanks, and happy crafting!
    • Instructions on how to install newer Java can be found in the FAQ
    • That's just plain wrong... newer versions are much better optimised and start a lot faster than 1.8.9, both Forge and Minecraft itself. Comparing Fabric 1.21 with Forge 1.8 is like comparing apples and oranges... one's brand new and the other's over a decade old.
