Handle multiple inputs at the same time?

[Browndog]

To get input for my program I take inputs from the keyboard by overriding OnEvent in IEventReceiver I think have a series of if statments to control movement of a node ie.

if(keyPress==LEFT)
{

turnLeft(1);
refreshScreen();
}

and so on for right, up, down, etc...

How could make it so that 2 directions can be used at the same time?

ie if up and left are pressed at the same time I would like to go up and left.

how about:

if(keyPress == LEFT && keyPress == UP)
{
doStuff(1);
}
else if(keyPress == LEFT && keyPress = DOWN)
{
doStuff(2);
}
else if(keyPress == LEFT)
{
doStuff(3);
}

Yeah I think that may work.

I guess I just have to have every combo covered. I'll give it a shot.

If anyone has a better method let me know .

No this will not work keyPress cant eq to two values ...

How about saving the key states between events as booleans

//(somewhere outside of event handler)
bool leftPressed=false, upPressed=false; //as many as you have actions

//(event handler)
if(keyPress==LEFT)
{
leftPressed = event->KeyInput.PressedDown;
}
else if(keyPress==UP)
{
upPressed = event->KeyInput.PressedDown;
}

//(maybe at end of event handler, maybe in main loop)
if(upPressed&&leftPressed) doUpLeftCombo();
else if(upPressed) doUpStuff();
refreshScreen();

That way, while the user is holding a key down, the value will be true, and when they release it will be false, then base your actions on the state of your set of booleans.

ah ok ic sounds interesting I'll give it a shot
