i''m using this to check for key presses #define keydown(x) (GetAsyncKeyState(x) & 0x8000) i want it so that when you press say space it makes you jump but then you have to let go of space and press it again to jump. how do it do thinf using async type thing. at the moment you can just hold down space and it keep jumping.

Simple and fast:

First define a macro checking for key up as well using the Async function, then have a bool called space, init it to true.
Then do something like this:

if(space)
{
// jump code...
space = false;
}
else if(keyup(SPACE_KEYWORD))
{
space = true;
}

Hard work:

Make an array of 256 that keeps track of every key. You will have to make your own keycodes (like ''A'' equals 1 and so on...). But this is pesky if you only need to stop space from going rapid.

Also, don''t use GetAsyncKeyState(), use Windows messages. This way you don''t have to poll the keyboard, you just have to check the boolean values.
