Hi, I'm new to capabilities, I followed a few tutorials on how to create your own, and after creating the interfaces, capability classes, storage, providers and registering them and attatching them to entities, I'm getting an exception crash saying I'm registering capabilities multiple times, I dont see where.

Event that attatches capabilities to the player

I know I'm doing 1 capability per variable, I've seen that you can have multiple variables in 1 capability, I just wanted to make them as simpler as posible for start.

You do understand that this line:

https://github.com/xanderindalzone/customgunsmod/blob/master/src/main/java/com/xanderindalzone/customgunsmod/CustomGunsMod.java#L93

And this line:

https://github.com/xanderindalzone/customgunsmod/blob/master/src/main/java/com/xanderindalzone/customgunsmod/CustomGunsMod.java#L89

 

Do basically the same thing, right? Lines 89 and 91 each register one method specified, line 93 registers "all annotated methods" which happens to be...one method (line 137).

 

Then you have this line:

https://github.com/xanderindalzone/customgunsmod/blob/master/src/main/java/com/xanderindalzone/customgunsmod/CustomGunsMod.java#L80

Which literally does the same thing as line 89, registering the same method a second time.
