I was trying to make a fuction that detect if my holding object hit other objects or walls, floor whatever in the scene.
The method I hold object is learned from Youtube and it base on physic constraint.
It also set the object held in player’s hand as a primitive component named “Held Object”, and it’s in player’s blueprint.
Thank you for your response. I managed to make it work.
Since my grabbing logic is different from yours. Somethings need a little change and I follow your logic that bind event on grab and drop functions. It functions normally and meet my expectation.
