How to find weapon data structure in FPS game?
1. I look for a storage area near the bullet count and total bullet count to check the data changes after the weapon fires. This method does not allow me to find the data structure of the weapon.
2. I changed the weapon back and forth, and then searched the weapon data through the "unchange / change" method, but the data structure of the weapon was not found.
