Attached is a little file called event.e and keyread.e
The last is by Micheal Bolin and does just what you want. No inkey-buffers
at all. Instead it (the function get_keys in keyread.e) returns all
currently pressed keys (scancodes!) in a sequence. (ordered by which one was
pressed first).

Event.e is an interface that uses keyread.e
It allows you to set an initial delay and an repeat-delay for each key on
the keyboard (scancode of the key!).

You can use it like this:

include event.e

event_scankey (1, {10,5}, routine_id ("quit_proc"))

The routine to call is quit_proc. It will receive the pressed key (1 in this
case) as an integer argument. The sequence {10,5} means, initial buffer 10
after that use a buffer of 5.

You can offcourse also set it to {0,0}.

The biggest advantage is not the freedom to set the delays to any custom
value, but to be able to set a different delay for every key!

This means arrow keys can have a really quick response, while toggle keys
like a flashlight or something can have the normal type of delays.
(otherwise it would be impossible to use it effectively: Can you hold down a
key for 0.0001 sec ?? so that it only triggers once ??)

During your game (or your program, depends) you need to call.

update_events ()

It will call the associated routines for each key pressed.
I think this will help you out. Offcourse the credits go to Micheal Bolin,
who wrote the actual ASM keyhandler.

Nope, no one has yet made it, so why dont you give it a shot ? I have some
files describing its file-format laying around..


>& BTW, Thanx to Ralf for pointing me to #A0000 !

You're welcome.

Good luck all,
