In this video we'll look at an application of the Strategy Pattern to game dev in Godot 4. The Strategy Pattern is a programming pattern useful for switching how an algorithm works at runtime. We use it a little differently here to apply a variable set of upgrades to a projectile fired by the player. A very closely related term is "polymorphism" if you're familiar with that.
