In this chapter, we take a look at the BP_Pickup_Rifle and explain how the pick-up mechanics work and what happens when we shoot with the rifle.

BP_Pickup_Rifle has a SphereCollision component once a player overlaps with this invisible sphere, an event called On Begin Overlap fires off which first checks the overlapping actor and makes sure that it is a BP_FirstPersonCharacter, then saves a copy of that and checks if the player already has a weapon in their hands. If they do not, then it adds a component called BP_Weapon_Component to the FirstPersonCharacter.

• The BP_Weapon_Component is then attached to the hands of the player and then BP_Pickup_Rifle destroys itself.

• The BP_WeaponComponent handles the logic of spawning a projectile (Bp_FirstPersonProjectile), playing a sound of gunfire and an animation (for the arms).
