[Coco] OS9 Joystick/Mouse question

[Bill Pierce]

Steve, I figured as much. I don't recall any program ever "auto-recognizing" a mouse, but then again..... I've found quite a few things lately that programmers didn't ever do. It wasn't that it couldn't be done, they just didn't do it because it was too much trouble, not enough knowledge, or lack of the proper equipment. Usually a little of all three.

I guess on first run, I could prompt for "Press a button if using a mouse/joystick else hit ENTER" and then save it as a default in the program's config file. Of course this can be changed later in an options menu if so desired.

Bill,

No.

Have you every wonder why CoCo games ask if you using a Joystick or 
Keyboard to play?  That's why.  (If they did not then they must have the 
joystick plug in to play.)

The Joystick hardware in the CoCo can only gives a value from 0 to 63 
based on the Position/Voltage.  There is not data that can be returned, 
like an error state of no device plugged in.

Yes, there is a number returned when nothing is plugged in.  But, that 
number is same as the Joystick in that same position.

My easy trick was to look for the Button pressed of the joystick the 
player wanted to use and go from there.
