Simple Multi Directional Shooting

[stilianos]

I'm having a little trouble coding in multi-directional shooting in my game:

Basically I have:

if (left)
			{
				player.x -=  player.agility;
			boltDir = 270;
			}
			if (down)
			{
				player.y +=  player.agility;
			boltDir = 180;
			}
			if (right)
			{
				player.x +=  player.agility;
			boltDir = 90;
			}
			if (up)
			{
				player.y -=  player.agility;
			boltDir = 0;
			}
			
			if (up && right)
			{
				boltDir = 45;
			}
			if (up && left)
			{
				boltDir = 315;
			}
			if (down && right)
			{
				boltDir = 135;
			}
			if (down && left)
			{
				boltDir = 225;
			}

boltDir is the direction of the fired object, the above code works great, the only problem is 50% of the time if you are trying to do a diagonal shot for example up-left, it will get stuck and go left or up not diagonally.

Anyone know how to improve this?

Thanks

How are the down, left, up, right values set?

event listener of keyDown and keyUp for the arrow keys.

Okay, that sounds like it *should* work.

Throw some traces in there to see if the values of them are right, and if the "if" statements are executing when you'd expect them to.

trace('values=',up,right);
if (up && right)
{
	trace('up + right');
	boltDir = 45;
}

If these are all working as you'd expect, look next at what it does with boltDir. If the values aren't right, double-check the keyDown and keyUp listeners.
