Ok, so what I need to do is rotate the player from

Try raycasting down, then reading the 'normal' of the floor. Then rotate the player to match the 'normal' s rotation to the floor. I had the same problem , but luckily Aldo Naletto provided the solution.

My question : http://answers.unity3d.com/questions/230216/why-am-i-getting-a-fruity-effect-from-my-raycast.html

Aldo's other post (with illustrations from the question's asker similar to yours) : http://answers.unity3d.com/questions/168097/orient-vehicle-to-ground-normal.html

So you have both js and C# versions, hope this helps a little =]

yes there is and its quite simple just get the floors rotation and make the cube as it rotation like so (Javascript)


var Cube : Transform;
var Floor : Transform;
function Update()
{
     Cube.rotation = Floor.rotation;
}

drag (in editor) the objects into their designated spots

Do you really think I couldn't have done this? That picture up there is just to show what I mean. I will have different curved floors in my game that won't work with this code.

Im sorry it is quite hard to give help with the litte information provided, i wasnt believing you couldnt have done this , it was just a misunderstanding. Anyway a cube is a complex object to use because its flat sides. Two other options. You can make it go through the floor or you can have it with only various parts of a flat side touching the ground. Sorry for any inconvenience :)

@dzebna, I'm also looking for a solution to this as this is something that I'm also trying to implement in my project. I have a round space station (2001: A Space Odyssey) and I need to have the player rotate to the floor angle as they walk around in it. Were you able to resolve it?

e.g.

 var rayHit : RaycastHit;
 if (Physics.Raycast(transform.position, Vector3.down, rayHit, 5.0)) {
     transform.rotation = Quaternion.LookRotation(rayHit.normal);
 }

Rotate player towards the floor
