I just finished fixing those errors. Thank you for pointing them out.
I moved my @CapabilityInject to my EventHandlerCommon.java to see if that may solve anything, but it does not seem like it has. The way I am attempting to check if my player has the capability is by right clicking with an item with the following code:
The way I see it, if the player has the DESTRUCTION_CAP capability, then there will be a chat message that shows the points, which is starting at 0 points. I'm instead getting a null pointer exception whenever I right click with this item. Is this a bad way to go about checking if I have the capability?
