How to add sliding ability

In order to add sliding, recreate this blueprint inside BP_CharacterBase

slide

slide_tl

What this does is basically:
-Do a linetrace in front of the character
-Check if CTRL is key being held, and character is moving, but not in the air
-DoOnce (to prevent it from stacking up)
-Play montage for the character mesh (melee unarmed at 0.5 speed used in this tutorial)
-Use a timeline to lerp the current location to where ever the linetrace ends
-After timeline is finished, reset the DoOnce
-Crouch is there to make the capsule smaller
-Camera gets moved down when sliding, but by the same amount gets moved up when sliding ends
