Keeping a transform position 5 units above ground at all times

Hi, question as the title says, I'm not exactly looking for a physics hover script with a pid, as I didn't like the result of that especially when the object is moving very fast and the slope of the ground quickly changes or loops (goes upside down).. I want the object to stay "glued" at that height using a simple transform position functions, like:

Code (CSharp):

1. transform.position.y = groundPoint(transform.position) + 5.0f;

suggestions?

 

Looks to me like you've pretty much got it; you just need to fill in the groundPoint method. You'd do that by casting a ray down, to intersect with whatever you consider to be "ground".

Also, you can't just assign to transform.position.y like that. You'd need to do something like:

Code (csharp):

1.    Vector3 pos = transform.position;
2.    pos.y = GroundPoint(pos) + 5;
3.    transform.position = pos;
