[1.7.2] Why Won't My Fish Mob Work?

MagnumMike55 · August 3, 2014

Hello everyone. I'm having difficulties with my water mob. For some reason it will just stand there and after a little bit, they'll just die. Here is all the code for my fish mob:

bump

TehSeph · August 4, 2014

Why didn't you just edit your post here and bump that?

MagnumMike55 · August 4, 2014

Because I didn't have the code inserts so the post was extremly long.

nexusrightsi · August 5, 2014

the reason your mob didn't work is because you haven't registered it in the common proxy

MagnumMike55 · August 5, 2014

I already put it in my client proxy. Do you have to put it in the common proxy or not?

nexusrightsi · August 5, 2014

that is just the part for rendering the mob, but you forgot the part where you register the entity itself with an id

jabelar · August 5, 2014

Yeah, it is interesting but if you don't register an entity it can do some funky stuff. Surprisingly you can still spawn entities without registering them, so sometimes it is hard to realize you made the mistake of not spawning them.

MagnumMike55 · August 5, 2014

Is this what your talking about?

private static int startEntityId = 300;

Because if it is, then that's not the problem

SanAndreaP · August 5, 2014

Is this what your talking about?

private static int startEntityId = 300;

No:

https://github.com/SanAndreasP/ClaySoldiersMod/blob/master/java/de/sanandrew/mods/claysoldiers/util/ModEntities.java#L36-L45

Also I register them inside init.

nexusrightsi · August 5, 2014

this is what I meant, i'm working on 1.6.4 so it might be different in 1.7

EntityRegistry.registerGlobalEntityID(EntityThrowingAxe.class, "ThrowingAxe", EntityRegistry.findGlobalUniqueEntityId());

EntityRegistry.registerModEntity(EntityThrowingAxe.class, "ThrowingAxe", 0, instance, 128, 1, true);

SanAndreaP · August 5, 2014

this is what I meant, i'm working on 1.6.4 so it might be different in 1.7

EntityRegistry.registerGlobalEntityID(EntityThrowingAxe.class, "ThrowingAxe", EntityRegistry.findGlobalUniqueEntityId());

EntityRegistry.registerModEntity(EntityThrowingAxe.class, "ThrowingAxe", 0, instance, 128, 1, true);

You can (and should) omit the line with the global entity ID.

Even if you want to register your mobs to the spawn eggs, you should make your own, mimicing the vanilla ones; there are ca. 32000 item IDs available.

nexusrightsi · August 5, 2014

but doesn't this automatically set a new id for the entity if its been taken already?

MagnumMike55 · August 5, 2014

Well I have this in my main mod class:

	private static int startEntityId = 300;	

                EntityRegistry.registerGlobalEntityID(EntityFishMob.class, "Fish", EntityRegistry.findGlobalUniqueEntityId());
	EntityRegistry.addSpawn(EntityFishMob.class, 10, 2, 4, EnumCreatureType.waterCreature);
	EntityRegistry.findGlobalUniqueEntityId();
	registerEntityEgg(EntityFishMob.class, 0x0033FF, 0x003399);

That and this to register a unique entity id and to register an entity egg:

	private void registerEntityEgg(Class<? extends Entity> entity, int primaryColor, int secondaryColor) {
	int id = getUniqueEntityId();
	EntityList.IDtoClassMapping.put(id, entity);
	EntityList.entityEggs.put(id, new EntityEggInfo(id, primaryColor, secondaryColor));
}


private int getUniqueEntityId() {
	do {
		startEntityId++;
	}
	while(EntityList.getStringFromID(startEntityId) != null);
	return startEntityId++;
}

}

Can anyone tell me what is wrong?

MagnumMike55 · August 6, 2014

again another bump .

SanAndreaP · August 6, 2014

but doesn't this automatically set a new id for the entity if its been taken already?

registerGlobalEntityId registers your entity to the vanilla ID list, which is limited (max. 255 entities)

That's where registerModEntity exists, the ID you provide there is mod-specific, beginning with 0 and counting up for each entity.

If you want to make a mob spawn egg, make your own and mimic the function of the vanilla one.

	private static int startEntityId = 300;	

                EntityRegistry.registerGlobalEntityID(EntityFishMob.class, "Fish", EntityRegistry.findGlobalUniqueEntityId());
	EntityRegistry.addSpawn(EntityFishMob.class, 10, 2, 4, EnumCreatureType.waterCreature);
	EntityRegistry.findGlobalUniqueEntityId();
	registerEntityEgg(EntityFishMob.class, 0x0033FF, 0x003399);

EntityRegistry.registerGlobalEntityID(EntityFishMob.class, "Fish", EntityRegistry.findGlobalUniqueEntityId());

Again: you shouldn't use this, use registerModEntity

EntityRegistry.findGlobalUniqueEntityId();

This line is completely useless and just wastes one of the limited entity IDs

registerEntityEgg(EntityFishMob.class, 0x0033FF, 0x003399);

As stated previously, make your own spawner egg, it's not that hard.

nexusrightsi · August 6, 2014

Right! cheers for the info. I'll change it as soon as im done with this annoying player render event

MagnumMike55 · August 7, 2014

I'm still having trouble understanding this. My mob won't move and it dies after a certain amount of time becuase the entity id isn't registered? Or what? I'm completly lost. I think if I know whats wrong, i'll understand my situation a little bit more.

Nothing to do with any entity ID, something in your entity code is wrong, I can't tell what, though.

Maybe see what the EntitySqid class looks like?

Anyone?

I guess i'm back to bumping . Can anyone help me? I've been trying all day to try and get this to work, I would search around the minecraft forge forums and find nothing. I would look deeply into any code that involves underwater entity methods and or the entitysquid class and end up with no success. I'm not a noob(even though I kinda sound like one), I know how to code with java, but I have no experience on how underwater mobs work. So even if you don't know how to fix this, can you please point me out in some direction to learning how water mobs work? Any help would be appretiated.

1. Don't post Mojang code! It's illegal and also we can just look that up ourselves.

2. Add @Override to all your methods you intend to override, it helps you see if you really override the method and not just declared a new version of it which never gets called.

3. return true in isInWater() and see if it still dies.

4. A bump after 4 hours, really?

It's illegal to post Mojang code? woops. Sorry if I seem desperate, but thanks for the reply!

Well, then please edit your post and remove the EntitySquid and EntityWaterMob code.
