i was wondering if you can help me build destructible crates that drops multiple or single item of the same kind , much like crash bandicoot crates in this video
I’d use an actor blueprint for each.crate… Google for how to do a destructible… when the crate is hit and falls apart, spawn your particles and powerup/ equipment drop (another actor)… there are also YouTube videos for this… good luck! 
thank u so much but can u give the link for the video??
your welcome! there are a bunch of tutorials on youtube… just run a search for “ue4 destructible tutorial” and “ue4 pickup tutorial”
