I'm trying to make a water creature (a fish) that is passive and will spawn in river and oceans. To handle is movement and AI i've looked at how guardians works and the mob itself works fine. But it doesn't naturally spawn in the world. I've registered it like this

EntityRegistry.addSpawn(EntityClownFish.class, 50, 5, 10, EnumCreatureType.WATER_CREATURE, Biomes.RIVER, Biomes.OCEAN, Biomes.DEEP_OCEAN);

 

But the game tries to spawn it on ground and not in water (so the canSpawnHere will return false and the fish will not spawn). So how can i make it actually spawn in the water? This is the entity class i'm using

Don't blame me if i always ask for your help. I just want to learn to be better :)

Try extending public abstract class EntityWaterMob instead.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.

But it still try to spawn on ground :(

Don't blame me if i always ask for your help. I just want to learn to be better :)

My only suggestion is to set a few breakpoints in EntityWaterMob and then hope to catch a squid or guardian in the act of spawning. If you find a water temple first, there should be plenty of activity to trap. Examine the methods in the call stack and look for anything that looks like it's in a branch following a land/water entity test. Keep your fingers crossed hoping that the test isn't specific to vanilla mobs by name.

The debugger is a powerful and necessary tool in any IDE, so learn how to use it. You'll be able to tell us more and get better help here if you investigate your runtime problems in the debugger before posting.
