Sheepishly, I am not sure how best to separate a long script into smaller scripts.

Typically, I have a large script that contains all the logic, and all the code. There are huge sections just dedicated to detecting single finger touch, two finger touch, etc.

In general, I would say the multitouch features can be segmented out - this would save me from scrolling through a lot of code just to jump to the right section.

But, how do you break it up into smaller files, especially when the I/O is polled from the same Update()?
