[Solved] Mobs won't animate


Recommended Posts

I've made a custom mob, I've got the entity file, the render file and the model file

I know the render file is rendering the model because I added extra objects that are showing up

The only trouble is my mobs won't animate

They won't walk, they just jump from place to place after lagging for about 10 seconds


I've looked over ever entity, render and model file in vanilla to find out what I'm missing, I've checked over the code at least a hundred times, everything is how it should be, I just can't work out what's missing


I'll add the code for the three files below


Render File

     * (Render<T extends Entity) and this method has signature public void doRender(T entity, double d, double d1,

Part in the main file where I registered the entity and render


	EntityRegistry.registerModEntity(EntityDemon.class, "Demon", 2, this, 42, 252, true);
	EntityRegistry.addSpawn(EntityDemon.class, 100, 1, 2, EnumCreatureType.monster, Deadworld.deadBiome);
	LanguageRegistry.instance().addStringLocalization("entity.EntityDemon.Deadworld.name", "Demon");

	RenderingRegistry.registerEntityRenderingHandler(EntityDemon.class, new RenderDemon(null, 0));



So, unless I'm, literally, missing another file that animates the mob, I have no idea what I'm missing and if it is another file, I have no idea which it is


Any help would be appreciated, because I'm officially out of ideas

... you know those moments where you're very happy but also want to scream because the solution was so simple?


I'm having that now


Thank you

That worked :D

In which case, what was the number you used? That would be nice, because I don't really know; I was just guessing and I need help with entities myself.

I lowered it incrementally

... tbh I don't even know why it was so high

in the end I just used 1


so it's


EntityRegistry.registerModEntity(EntitySpiritMob.class, "Spirit", 1, this, 41, 1, true);


It was kinda jumpy at 10 but a lot better, so I imagine 1 - 5 would work nicely
