Keeping the camera above the ground

Unity Engine

Howdy All,

Just a quick question. Anybody have any suggestions on keeping the third person follow camera from going “underground” when moving around the terrain? I’d appreciate ANY help at all.

Thank you,

if(transform.position.y <= 0)
transform.position.y = 0;

Thanks for the post,

I plugged that bit into the script but it doesn’t seem to be having any effect. I’m not getting any errors either. Any thoughts?

By the way… I love that picture.

the previous example assumes you have flat ground everywhere for y = 0.

To do what he suggested you really need to do a raycast from above on your terrain then use that y value. You might need to add a small amount to it to ensure it is above the terrain.

Thanks a lot Raider!

How exactly would I go about accomplishing that raycast task?

Expert from a previous post

			// raycast test for distance
			dist=distance;
			var hit : RaycastHit;
			if(Physics.Raycast(camera.position, currentRotation * -Vector3.forward, hit, distance)){
				dist=(hit.point-camera.position).magnitude - 1;
				
			}

Look into that code for a better explanation of what it all does, but that is the code that does a raycast from the target (focalpoint) to where the camera should be and gives the distance to that point. (minus 1 unit to prevent clipping)
