[gameprogrammer] Re: Key Repeat problem

Sorry if this is a dumb question, since I'm not familiar with linux, but is the behavior consistent regardless of any settings you try with SDL_EnableKeyRepeat(delay,rate)? have you tried a 0 for delay, which should turn off key repeating, and if that didn't work, how about the other extreme - something like 30000? (not likely that they would hold one direction arrow down for 30 or more seconds at a time, is it?)
Again, sorry if it's a dumb question/suggestion - but I had to throw it out there!

That's what I do when it's running under Windows. Unfortunately, knowing what the state of the keypress is under Linux is the crux of the problem, due to the constant keypress/keyreleased events being fired when a key is held down.

Or maybe store the state, only pass the message on to the network server if the state changes. The state would store whether the key is pressed or not....

Maybe in your KeyPressed function store a timestamp in a static variable and the next time the function is called only pass the message on to the network server if the time elapsed is greater than a certain number of milliseconds?

    I think this problem is purely with Java on Linux, but if anyone can
    think of a workaround it would be much appreciated.

Basically, I have two functions, KeyPressed() and KeyReleased(), which
normally get called (only) when a key is pressed and then released
respectively. However, if you hold a key down when running it on
Linux,
it fires each one pretty much constantly in turn for as long as
the key
is held down. My program is a network client for my game, and I send
keypress and keyrelease signals to the server. With the above
symptoms
though, the server gets clogged up with constant signals from each
client when a single key is held down.

    It is a known "symptom" of Java under Linux, but can anyone think
    of a
    work around?

    Thanks in advance,

    Stephen
