- or otherwise.

- ** INTRODUCTION:***********************************************************
-
- JoyRide is a commodity that provides an intuition front-end for joystick
- events. This has some nice advantages for both users and programmers.
-
- There are three (3) basic features you get:
- a) A simple joystick interface through a window's IDCMP port.
- No joystick-specific code has to be used, JoyRide initializes and
- handles all the trigger-setting and reading of the joystick.
- The joystick events are passed to your application in the same
- manner as all other intuition events through your window's IDCMP,
- just like IDCMP_RAWKEY and IDCMP_MOUSEBUTTON.
- b) Application shareable joystick events.
- Normally, only one application can allocate the joystick at a time.
- In other words, no two applications that both use the joystick can
- multitask. JoyRide handles this in the same manner the
- keyboard.device handles key presses. That is, it sends them down
- the input.device where they are passed to the active window
- (or "input focus"). In this way, many programs can now share
- joystick events.
- c) Joystick events now pass through the input.device stream.
- This is helpful because now screen blankers know that you're
- using the computer and won't blank during joystick games!
-
- AmigaOS should already contain this functionality. Perhaps in the future.
- Until then, JoyRide can potentionaly add usefulness and flexibiliy to
- using the joystick in an OS friendly manner within your applications.
-
- ** USAGE:******************************************************************
-
- JoyRide runs only under AmigaDOS 2.0 and above.
-
- Basically, you can just put JoyRide in your WBStartup drawer or any other
- convienant location. By double clicking on its icon (or typing its name
- from a shell) you can alternately start and stop JoyRide. Since it is a
- commodity, it can also be deactivated or removed through the commodities
- Exchange program.
-
- Note also that JoyRide is basically incompatible with previously written
- applications that use the joystick, and will most likely have to be
- terminated before any such programs are used.
-
- ** HOW TO IMPLEMENT:*******************************************************
-
- Joystick events are sent as IDCMP_RAWKEY events. The "Code" field of your
- IntuiMessage will contain a 0x7F (which is an unused rawkey code, and is
- not used by any keyboard). The presence of this value means that a
- joystick event has occurred. The status of the joystick is contained in
- the "Qualifier" field. The directional values are indicated by the
- presence of the following bits:
-
- +--------+----------------------+
- | Status | Qualifier bits |
- +========+======================+
- | Right | IEQUALIFIER_RSHIFT |
- | Left | IEQUALIFIER_LSHIFT |
- | Down | IEQUALIFIER_RALT |
- | Up | IEQUALIFIER_LALT |
- +--------+----------------------+
- | FIRE | IEQUALIFIER_LBUTTON |
- +--------+----------------------+
-
- The absence of all these bits naturally indicates that the joystick is in
- the upright position, and the button is not pressed.
-
- Please see the example program "joy_tst.c" that should be included in this
- archive.
-
- Additionally, JoyRide opens a public port named "JoyRide" that may be
- searched for (via FindPort()) in order to asses whether or not JoyRide is
- currently in use.
