Hello,

I currently have a sketch here, that runs a video in a circle that follows the mouse. I would like to get it so that the video changes when a button is pressed.

I have it that the video changes while one is holding the button, but i want one press to equal a sort of "play" button, i will have multiple buttons all wired to a different video.

This code also seems to run really slow, any ideas on how to improve that aspect are welcome as well.

thanks
