Multiple keyboard presses

[abbeywell]

I am currently working on a multiplayer air hockey game which, if played by two human players from the same computer, requires the two paddles to be controlled from the same keyboard by each player (for instance).

I have created two classes which extend the Behavior class, each controlling each two paddles. processStimulus() is called every time a key is pressed however, no two keys can be pressed at once, so the game is unplayable. Is there a way to allow multiple key presses?

Thanks,

AW

The general approach to this is to keep track of a boolean for each key you care about. On keyDown, set it to true, on keyUp, set it to false. Then in your game loop, check those booleans to perform the appropriate actions.

Sorry, but that seems like a pretty crappy solution. Why on earth would you need a separate Timer for each key?

Be aware that you might run into hardware issues. I used to have a Microsoft keyboard on which, if more than two keys were pressed simultaneously, the release of keys after the second was not detected, simulating stuck keys.

I cant seem to get it working unless I use a different timer for each key. Could you be more elaborate?
