Set Quaternion to another Quaternion, but oriented along
Hey guys, quick question--
I am trying to stick a robot's foot to the terrain but I am having trouble laying it flat. I am using a raycast firing down into the terrain which gives me the hit.normal, the z-axis of which points upwards. I want the foot to stick to the hit point but have its y-axis pointing up along the normal. I also want the foot to rotate along its y-axis to the same angle as the robot.
So basically I'm thinking I need to do this (pseudocode):
foot.rotation = hit.normal(along z axis); // This is what I can't figure out
foot.eulerAngles.y = robot.eulerAngles.y;
I'm sure there's a simple way to do this. Thanks for the halp! You guys own.
foot.rotation = Quaternion.LookRotation(robot.forward, hit.normal)
works for the y and z rotations, but the foot does not slope 'downwards' or 'upwards', that is, the x rotation remains locked at 0.
Managed to get it workin well enough by firing off two raycasts, one from the back of the foot and another from the front, then doin:
Quaternion.LookRotation(footFrontHit.point - footBackHit.point, footBackHit.normal);
foot.transform.eulerAngles.y = robot.eulerAngles.y;
Hey Sarge! You might be best to close or delete this question ('asked and answered") (or some rude ad$$anonymous$$ will do so! heh)
quaternions are a hell of a business, eh
Hah, no kiddin! Yeah I'll close it. Thanks boss.
