Virtual Keys

I'm trying to trap the 'W' key with the following code, but it doesn't work:

if (KEY_DOWN(VK_W))
	// Move player two up

if (KEY_DOWN(57))
	// Move player two up

Neither works...

Try using GetAsyncKeyState instead of KEY_DOWN.

What is KEY_DOWN?? Where did u get that? Is it a MACRO of some sort? Try what abdul said or just do a

#define KEY_DOWN(x) GetAsyncKeyState(x)

I've had troubles with it

[abdul]

GetAsyncKeyState will return 0 if it fails so you should check it like this....

if(GeAsyncKeyState(0x57) != 0)
{
//Key was pressed
} 

Remember the code for the "W" key is in hexadecimal (0x57), not just 57.

oohhh! now I get it! thx!

The return value of GetAsyncKeyState should only be tested for the highest bit set:

inline bool KEY_DOWN(int vk) {
  return (GetAsyncKeyState(vk) & 0x80) != 0;
}
