I have an RPG in production, and I wanted to make a crafting system, combat system, etc. For my crafting system, I want to use an axe that I currently have, and I wanted to use it as a tree cutting axe. Would I use the onprojectilehit event? If I did that, a bow or sword would also work. How would I make it so only my axe works to cut down trees? Also, I know how to make a basic EXP system with variables, but how do I make a message appear in the center of the screen when your EXP reaches a certain level?
