[1.7.10] Sitting Isn't Unique To The Entity

qpwoeiruty · July 25, 2014

I have a custom entity that when sitting changes position like a wolf. However, despite it working fine, when another of my custom entity is walking, the sitting entity starts to perform the walking animation even though I have specified it to be only when it isn't walking.

That sort of thing usually indicates some sort of static field or method is involved. However, I can't see any problem when quickly looking at your code -- it seems you're just extending the standard EntityTameable functionality for sitting. And you don't have any static fields or methods that would mess you up.

One thing I've never liked about the sitting is that the AI sitting field is private so you need another field in the entity and have to keep them synced -- it would be better to simply have a getter in the sitting AI class. However, that isn't your problem here either.

I don't see any static fields or methods in your code that could cause trouble.

So the next idea might be related to client-server syncing. The isSitting field is (in EntityTameable) stored in the datawatcher which should sync automatically. Are you doing anything weird to separately sync the fields of your entity? Or are you using the datawatcher yourself?

It was fine in my old mod which I am just rewriting, but I might try writing my own field to NBT then syncing it using packets.
