You would have to use the keystate command, and check each key that could be pressed.

Alternatively, don't use the DBPro functions at all. Use the windows GetKeyboardState function instead - it will provide a snapshot of all keys currently pressed, including the 'state' keys (Ctrl, Shift etc)

hmm yea i might have to

check this out

int getInput() {
int kmap = 0;
//keymap.map is an array containing the scan codes of keys to look for
for (int i=0; i<KEYMAP_SIZE; i++)
if (dbKeyState(keymap.map[i]))
kmap |= KEYMASK[i];

return kmap;
}

only returns the first couple of keys pressed
it could be because of an inherent logic flaw i havent noticed but the logic is straightforward and the masks are all unique.

loop through keys that are mapped to actions
for each key
if the key is pressed, add the corresponding mask to the flag

return the flag
