Create a dynamic gun modifier system to enable runtime property changes of your guns! We'll also cover how to prevent ScriptableObjects from persisting these changes in the editor.
In this video we'll set up a modifier system and implement 2 popular modifiers:
1. Damage Modifier, which allows us to raise or lower the damage of any gun when it's applied.
2. Vector3Modifier, which allows us to apply a percentage offset to any Vector3, such as the Bullet Spread amount.
