Question by TechSupport · Jan 17, 2011 at 09:52 PM · rotationraycastingnormalsalignment

Contour gravity

all I need is this: (I think)

Send a raycast down and find the surface normal, and set our rotation to that normal.

Could you provide me a script maybe explaining normals and raycasting to set our rotation to that normal?

That way I can use that to learn normals in alot of ways.

Thanks.

Lots of examples can be found in the reference: Physics.Raycast

The normal of the surface the ray hit: RaycastHit.normal

To rotate an object (e.g. when instantiating) you can use this normal as the forward-vector for Quaternion.LookRotation.

Thank you. I knew how to use raycasts to alter your position, but I wasn't too sure about the rotation part. and I wasn't sure where to look. But thank you.
