So I'm making a 2d game using sprites. I want many keys to be pressed at once. EG: W for walking, D for rotating, And R for reload all at the same time, But as of right now, Only 1 will be executed at a time. here's my code for the movements.



The above code is 1 of many sub routines I have implemented, just don't wanna paste all my code here

So yes, I'm sure this is an easy fix (I was just thinking of a fix using the "while" command, but I have no time to test this right now).

Any help is appreciated! Thanks!

SCANCODE() was designed to learn the numbers of each key. It only shows the lowest numbered key that's hit. Use KEYSTATE() to actually detect keys so you can detect multiple keys. The only other use for SCANCODE() is to detect no keys being pressed (when you want the user to let go of all keys before moving on in code).

Ah, Thank!

I was attempting to use keystates, But I though they where different than scancodes. (I was using the numbers from the ASCII character codes image in the "Principles" help files for keystates)

Thanks again!

Oh, the ASCII Chart numbers are different. Here's my Keystate Map for quick reference (rather than using SCANCODE() every time you want to know the KEYSTATE numbers).
