I have a cow. He's just basic, doesn't even have a walking animation. So, I want to get a custom milk bucket from him, the filled bucket is named "GMMilk."

 

What I wish to learn: How to get that milk bucket instead of the normal one

So... breakdown.

1. Right click the custom cow with an empty vanilla bucket

2. Get a "GMMilk" bucket but NOT a "milk_bucket" bucket

 

Thanks in advance! Have a nice day

Have you looked into EntityCow source? Without looking I am pretty sure code responsible for filling bucket with milk is in onInteract (or similar name) method. If it's not in entity, it might also be located in ItemBucket (again - something along interaction).

Override it, and do almost same thing but differently.

Found it! Thanks
