1. I' currently working on EBO engine and it have implemented pet system. Pet is attacking mobs but mobs aren't attacking my pet. It can be changed? 2. How to make items that can be used only one-time. I want to create scrolls with spells that after one use will dissapear 3. I want to make a builder class in game. Builders can for example repair bridges. If bridge is repaired then everyone for 1 hour will be warped to another map. After a hour bridge will be again broken. How I can make it?
