How do I change through weapons with scroll wheel in a FPS game?

Hey!, I am a beginner with UE4 and I wondered if anyone could help me create a system that allowed my character to scroll through various weapons using the scroll wheel on the mouse.

(this is for a class project demo not a full videogame)
(I am working on version 4.27)

If any more information is needed just let me know and I’ll add my project details as soon as i can ^^

  • keep weapons in an array
  • increase / decrease index when scrolling up / down
  • ensure the index wraps into array bounds
  • fetch desired element from the weapons array and store its refernce

Ideally you’d add some kind of actor validation to make is safer.

Make list of weapons in some array.
Detect scroll mouse event
read next/previous weapon from array,
destroy old one spawn new one attached to hand bone.

Done.
