Use the sub-routine OnTouchStart in VBScript to perform an action when the user starts touching the project screen or screen object.
Sub OnTouchStart(x,y) … End Sub
- The starting x-coordinate (in pixels from the left of the screen) of the first touch point.
- The starting y-coordinate (in pixels from the top of the screen) of the first touch point.
This is a sub-routine (as opposed to a function) in VBScript, so it does not return any value.
This sub-routine is based on the method ManipulationStarted in the Windows API. For more information, go to “Windows Touch Input” on the Microsoft Developer Network website at: msdn.microsoft.com/library/dd317321.aspx
The sub-routine is executed once when the manipulation is started — that is, when the first touch point is added to the project screen or screen object. Additional touch points after the first do not trigger this sub-routine.
You are not required to use the received parameters in your code. They simply make the raw touch input data available to you, for you to use (or not) as you deem necessary.
