[1.8] custom mob errors

ulfgur
in Modder Support

Featured Replies

Posted

This is my first time through building a custom mob. I'm taking the chicken as my base, and ATM am just trying to get it to render & behave like a chicken.

 

I can spawn the mob. I'm guessing it has chicken-like behaviors, but I can't see it. I can, however, hear it.

 

Here is my registration code:

 

//in client proxy, init

RenderManager reman = Minecraft.getMinecraft().getRenderManager();

    RenderItem reIt = Minecraft.getMinecraft().getRenderItem();

 

RenderingRegistry.registerEntityRenderingHandler(EntityTutorialMob.class, new RenderTutorialMob(reman, new ModelChicken(), 0.5F));

 

////////////////////////////////////////////////////////////////////////////////////////

//in common proxy, init

EntityRegistry.registerGlobalEntityID(EntityTutorialMob.class, "TutorialMob", 900, 230, 78);

 

 

 

 

Spawning the mob results in the following errors:

Any idea what could be causing this?

 

Thanks.

    Thank you! That partially worked! The mobs are visible...

     

    ..Now, I'm having a problem where the mobs kinda jerk around and teleport, while displaying chicken behaviors. (I'll hold seeds, they'll walk-teleport to me). They still animate. Any ideas?

     

    EDIT: My render & entity classes are literally copy-pasted (then refactored) from the chicken's. I'm getting something stupid-simple to work before I play with anything more complex.

    in commonproxy:

     

    EntityRegistry.registerModEntity(EntityTutorialMob.class, "TutorialMob", EntityUniqueIDFinder.getID(), MinecraftByExample.instance, 230, 78, true);

     

    in clientproxy:

    RenderManager reman = Minecraft.getMinecraft().getRenderManager();

RenderingRegistry.registerEntityRenderingHandler(EntityTutorialMob.class, new RenderTutorialMob(reman, new ModelChicken(), .5F));

     

     

    ...the stuff about entityUniqueIDFinder references this class:

    public class EntityUniqueIDFinder
{
public static int currentID = -1;

public static int getID()
{
	currentID++;
	return currentID;
}

}

     

    ...after reading your advice (but before understanding what you meant), I thought I wasn't supposed to define my own global ID, and tried using EntityRegistry.findGlobalUniqueEntityId() where that code was. It didn't work, (I was obviously doing something the stupid way), so I just wrote my own so I didn't have to track the all my entity ID numbers. :P

     

     

    And don't copy paste.

    Why? I'm gonna take it apart and find out how everything works later... This mod will not be released to the public...

    It was the update frequency that worked from my other entities, all of which are projectiles (for those, the update frequency was used by some tutorial I saw somewhere). I take it the update frequency should be something different?

     

    I did try upping it to 200, which didn't help at all. What value would you suggest? (also, am I doing it wrong for the particles, too?)

    I've got my mob working, analyzed much of the code, heaped wonderful loads of custom behaviors on it, and have it spawning in my custom biome.

     

    I'd like to add it to some of the mob spawners I sprinkle around the world. Unfortunately, when the mob spawner is generated, it's empty.

     

    (registration:)

    EntityRegistry.registerModEntity(EntityTutorialMob.class, "TutorialMob", EntityUniqueIDFinder.getID(), MinecraftByExample.instance, 230, 3, true);

     

    (The code that eventually creates the spawner:)

    WorldGenHelpers.genMobSpawner(world, pos.add(2, 1, 2), "TutorialMob");

     

    //Then, in a different class:

    public static void genMobSpawner(World world, BlockPos pos, String mobName)

    {

    world.setBlockState(pos, Blocks.mob_spawner.getDefaultState(), 2);

            TileEntity tileentity = world.getTileEntity(pos);

     

            if (tileentity instanceof TileEntityMobSpawner)

            {

                ((TileEntityMobSpawner)tileentity).getSpawnerBaseLogic().setEntityName(mobName);

            }

    }

     

     

    Any ideas?

    registerModEntity

    prefixes the entity's name with your mod ID followed by a period, so the full name of your mob is 

    "<yourmodid>.TutorialMob"

    .

    Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

    Agh. Should have thought to try that.

     

    Thank you! It's up and working!
