unity mouse scroll code example

Example 1: unity mouse wheel

Input.mouseScrollDelta.y //Return 1 when up and -1 when down and 0 when the mouse scroll is not rotated

Example 2: unity on mousewheel down

if (Input.GetAxis("Mouse ScrollWheel") > 0f) // forward
 {

 }
if (Input.GetAxis("Mouse ScrollWheel") < 0f) // backwards
{
               
}

Example 3: unity mouse click position

Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

RaycastHit hit = new RaycastHit();

if (Physics.Raycast(ray, out hit))
{
	return hit.point;
}
