Get hit direction from one gameObject hitting another
If I fire a gun (bullet) I use a ray cast (Ray.direction) to get the direction the ray was hitting the rigid body to add force.
impactTarget = hit.rigidbody;
impact = ray.direction * 12;
I then add force to the rigid body thats been hit with
impactTarget.AddForce(impact,ForceMode.VelocityChange);
And all works well with the bullet because it's instant, if I use the Ray.direction for the RPG by the time it's reached the target the ray cast could be looking somewhere else.
But how if I shoot a RPG (gameObject with small box collider) and hit the same rigid body do I get the direction of the RPG hitting from.
ImpactTarget = contact.gameObject.rigidbody;
impact = contact.??
I'm using for the collision detection
function OnCollisionEnter(collision : Collision){
var contact = collision.contacts[0];
Thanks.
The "direction" between any two objects is simply the difference between their transform positions.
var Direction : Vector3 = contact.transform.position - transform.position;
You may then want to normalise this variable - it's unclear from your question exactly what you want it for.
Thanks for the input, I want it so I can use the impact direction to add force to the part of the rag dolls rigid body, arm, leg, head .. where the impact happens then
impactTarget.AddForce(impact,Force$$anonymous$$ode.VelocityChange);
I say RPG in the above example, but anything thrown hitting the body part, brick, can, ect ..
You can simply find object(game object with small box collider) by Gameobject.findbytag and the difference between the found object vector.position and impacttarget.position will give you direction .
Thank for the input, thats what tanoshimi said "The "direction" between any two objects is simply the difference between their transform positions."
Also I'me using
function OnCollisionEnter(collision : Collision)
to do all the detection.
