Keyboard Controls

**Drakongd** · 10-30-2002

I wonder if you can help me with the following problem.

I want to write a function to accept keyboard controls and it needs to be able to accept multiple keys at the same time.

For example: If I have a key that when pressed rotates the screen upward and another key that rotates it sideway, but if pressed together they will move the screen at a 45 degree angle.

I dont have much experience with this and havent been able to find a function which allows you to do this. Any help would be much appreciated.

Thanks.

There is no function that allows you to do this , sorry.

I'd use DirectInput, or Allegro if you need more portability.

uhh, try DirectX controls, get the SDK from microsoft.com, its the only microsoft product i like, its 126megs, and FREE!

You could use the numpad, and make the 7,9,3, and 1 keys move in the varius directions. THis is a viable option, and can be done relatively easily.

I'm pretty sure you can watch for keyboard input with windows.h
Of course that only works IN windows, but there is a way of intercepting windows messages and checking if they are keypresses. I don't have the code on me at the moment, but I'll be back in a couple of hours and I can tell you then.

Yes, that is easier.

Code:

 
bool IsKeydown(int key)
{
   return GetAsyncKeyState(key) bitand 0x80;
}

//Test for up-arrow:
if (IsKeyDown(VK_UP)) ...

//Test for P
if (IsKeyDown('P')) ...

i know this windows game called Kieg. is a cheapy 5meg game where your in some sort of small cramped area and you get bombarded with enemies left right and center. and the controls are
w -> move forward
a -> turn left
d -> turn right
s -> move backwards
Tab -> fire weapon
