Hello, I am working on an item and I need to do something only once while the right click is pressed.

I looked at some vanilla items and some of them were calling OnItemStoppedUsing, I looked at some forge tutorials, the rifle tutorial is using the same function.

When I use it in my mod it never gets called, do I need to extend something special for it to work?

I wasn't setting the item as used, but, is there a way to not slow the player down?

I'd recommend looking at the code in the Item class for that method, it should have the code for making the player slow down, use an at override method on the one in your class and remove that line of code slowing the player down. Should suffice for your purposes.

I found the method but, overriding it, that never came into my mind, thank you for the idea:) Why it was slowing down the player it was because it was making the player have the same things as when eating, holding a sword, drinking potions.

Glad I could help. I am not the best with Java so whenever I get the chance to help I jump at it.

It was a good idea until I realized that the method that I need is in the player class
