Assume they both have collider, and able to contact each other in "layer collision matrix" setting I want to find out if my character overlapping something, and get the suggested direction vector from physic engine. during the Rigidbody.isKinematic = true; the first condition is rigidbody mush stay in Kinematic state. (can't let physic engine take control) in fact, I want to remove rigidbody as well. if anyone can point me the way to only use collider to find the possible direction vector will be better can't find it on google may be I missing the keyword. so any help are welcome. PS: I understand that may need to calculate bunk of Vector & Quaternion stuff, I should understand the basic.
