Hello i’m making a 2.5D game base for recording gameplay, i follow a turotial to make the character slide on surface with more than 21° angle, and i don’t know why he can’t jump during sliding.

Slide is equivalent to crouch. In UE, the character cannot jump when crouch.
This plugin related to slide based on Physics on Unreal Marketplace, which support Jumping while Sliding.
