Hi,

I want to create a bluetooth app to control a camera with a slider: I created a joystick for the X axis (button left) and a button (right) to take the picture.

How can I improve the code so I can use (and send the commands) the same buttons at the same time?

Ai2 does not provide multitouch. There is an extension that provides this. Look in the Taifun extension directory and search for multitouch.
But it still won't be easy with the extension. The blocks will have to be rebuilt.
