How did you manage to get the mouse wheel working in a webgl build?
Thanks for playing! I did nothing special, it just works. Here's the code I used (attached to the camera object)
public float zoomSpeed = 300f;
public float minY = 5f, maxY = 40f;
void Update ()
{
float scroll = Input.GetAxis("Mouse ScrollWheel");
pos.y -= scroll * zoomSpeed * Time.unscaledDeltaTime;
pos.y = Mathf.Clamp(pos.y, minY, maxY);
transform.position = pos;
}
