[1.12.2]Custom painting not rendering


TheMCJavaFre4k

Recommended Posts

Hi There

Ive been trying to create a identical painting item to default minecraft to later modify with custom rendering. Currently I've made a copy of the Entity, Render and Item classes and registered them(See below). With this code how it is, The entity seems to spawn as it has the behaviour of a minecraft painting, ie - breaks off the wall if a block behind is removed, but has no hitbox and is not rendered. I have tried finding information on this topic but since a custom painting item is such a niche thing to need, I haven't had much luck. Im hoping its just a registration problem and a simple fix. Any suggestions are welcome!

Renderer Registration in ClientProxy:

 RenderingRegistry.registerEntityRenderingHandler(EntityScreen.class, new RenderScreenFactory());

 

RenderScreenFactory:

public class RenderScreenFactory implements IRenderFactory<EntityScreen> {

	@Override
	public Render<? super EntityScreen> createRenderFor(RenderManager manager) {
		return new RenderScreen(manager);
	}

}

 

Entity Registration called in PreInit:

EntityRegistry.registerModEntity(new ResourceLocation("mcdj", "screenentity"), EntityScreen.class, "screenEntity", 0, MCDJMod.instance, 160, Integer.MAX_VALUE, false);		

 

If any more information is required, let me know.

Ive now moved to EntityEntryBuilder for entity registration, but as expected, it has not changed the situation.

The entity still doesn't have a bounding box or is rendered in any way but is being spawned.

 

New Entity registration code:

public static void registerEntity(RegistryEvent.Register<EntityEntry> reg){
		
		EntityEntry entityScreen = EntityEntryBuilder.create().entity(EntityScreen.class).id(new ResourceLocation(MCDJMod.modId, "screenentity"), 0).name("screenentity").tracker(160, Integer.MAX_VALUE, true).build();
		reg.getRegistry().register(entityScreen);
	
	}

 

 Any suggestions are appreciated.

Please post your code as a GitHub repository. Hardcoding 0 as your ID isn’t the best idea. I recommend registering entity renders in the model registry event. 99% of the time you don’t need a proxy.

Will probably swap to using a better ID system for my entities but just thought 0 would suffice for the single entity in testing.
