I'm using imgData to check if the alpha value of the pixels that surround any object = 255 ( and is therefore opaque) and then if so my moving objects (2 rectangles) cannot move into them (i.e. a wall). Because of this I can't use the rectsCollide function to check if they touch (because that requires an instance where the pixels overlap which my method does not allow). So in a 2 step question I need to know how to check if these two rectangles are touching and 2 if they are how to start a timer when they touch. I'll show you my jsfiddle so that you can see how I check for collision detection...
