Hello,

 

the problem I was having is actually seemingly solved, however I want to understand why I was having the error.
In the starting phase of minecraft there was the error:

[22:11:51] [Client thread/WARN] [FML]: Potentially Dangerous alternative prefix `leer:0` for name `meteorite`, expected `leer`. This could be a intended override, but in most cases indicates a broken mod.

 

and whenever I created a new world I also got the error that there was a missing registry entry.

 

This was the code of my Entity Registry:

Spoiler

public static void register(RegistryEvent.Register<EntityEntry> event) {
		int ID=0;
		//Meteorite
		EntityEntry meteorite = EntityEntryBuilder.create()
				.entity(Meteorite.class)
				.id(new ResourceLocation(LEER.MODID+":"+ID++, "meteorite"), ID)
				.name("meteorite")
				.tracker(100,10,false)
				.build();
		event.getRegistry().registerAll(
				meteorite
				);
	}

 

This is my "fixed" code:

Spoiler

public static void register(RegistryEvent.Register<EntityEntry> event) {
		int ID=0;
		//Meteorite
		EntityEntry meteorite = EntityEntryBuilder.create()
				.entity(Meteorite.class)
				.id(new ResourceLocation(LEER.MODID, "meteorite"), ID)
				.name("meteorite")
				.tracker(100,10,false)
				.build();
		event.getRegistry().registerAll(
				meteorite
				);
	}

 

As you can see the only change was the domain of the resourcelocation.

Thank you for your help!

Ok, so, your first code generates a registry name with two colons in it. Hence "dangerous prefix."

 

Your fixed code is fine, the reason for the missing registry entries is because your old code generated different IDs than your new code. This is fine, either load the world and have the blocks be deleted from it or generate a new world.

Thank you very much for your answer!
