How can I use the right mouse button instead of OnMouseDrag?

How can I adjust the following script to use the middle mouse button or right mouse button instead of the left mouse button? The script currently uses OnMouseDown, OnMouseUp, and OnMouseDrag.

using System.Collections;

Solution

  • OnMouseDown, OnMouseUp, and OnMouseDrag are only made to be used with the left click. What you need to do in order to implement with right click, is to use Input.GetMouseButtonDown(1) and Input.GetMouseButtonUp(1) in order to know the sate of the mouse button.

    Something like this : 

    bool dragging = false;
void Update()
{
    if(Input.GetMouseButtonDown(1))
    {
        yourOnMouseDownFunction();
        dragging = true;
    }
    if(Input.GetMouseButtonUp(1))
    {
        yourOnMouseUpFunction();
        dragging = false;
    }

    if(dragging )
    {
        yourOnMouseDragFunction();
    }
}

    There are better ways to do this but they will require more code.
