System to grab object in VR:

Principle:

• On trigger input (grab):
  • calculate the nearest component castable to Bp_grappable
  • return this component
  • disable physics on the object and attach it to the motion controller that trigger
• On trigger input (release):
  • activate physics to the object and detach it

Bp_grapable :

• inherite of BP_Outline_postprocess
• manage all parameters for collision,physics outline

Issue with physics and collisions :

sometimes overlapping problems that lead to instability during the manipulation of cubes.
To reduce this thanks to implementation of Brem RobCog
