Thread: The long-awaited Space Shooterz DX!

Although the least significant bit of the return value indicates whether the key has been pressed since the last query, due to the pre-emptive multitasking nature of Windows, another application can call GetAsyncKeyState and receive the "recently pressed" bit instead of your application. The behavior of the least significant bit of the return value is retained strictly for compatibility with 16-bit Windows applications (which are non-preemptive) and should not be relied upon.

It's best to use "& 0x8000", and it lets you get rid of the bare GetAsyncKeystate(); in your code (which puzzled me at first).

This is not important at all, though. Just a thought.

Edit: 0x8000

It's best to use "& 0x800",

Huh? Wait a minute, didn't you say 0x8000? Also, would it work to use LOWORD() and HIWORD() to check instead?

Never trust me, trust the Win API documentation.

HIWORD and LOWORD won't work, but perhaps HIBYTE and LOBYTE will.

*smacks head* Right, it's only GOT 2 bytes
