object follow mouse position in 3d world.
here code that i using
var s : Transform; function Update () { var ray = Camera.main.ScreenPointToRay (Input.mousePosition); var hit : RaycastHit;
if (Physics.Raycast (ray, hit))
{
//Debug.Log(hit.point);
var a = hit.point;
s.position = a;
}
}
it not working. something like object go to camera position. how to fix it?
my camera position like 2d camera.. but i want to make 3d world
if you want your world to look 3D, you should be using a perspective camera. in that case, you will want to use Camera.ScreenToWorldPoint(), which takes view space coordinates. do this for both zNear and zFar because the x/y values of each point will almost always be different in perspective view. ray.origin is the transformed zNear point, and ray.direction is the normalized delta between then zFar and zNear point.
actually you do not need to normalize the direction value. you can just use var m = Input.mousePosition; var nearPt = Vector3(m.x,m.y,Camera.nearClipPlane); var farPt = Vector3(m.x,m.y,Camera.farClipPlane); ray.origin = ScreenToWorldPoint(zNear); ray.direction = ScreenToWorldPoint(farPt)-ray.origin; ...
