[SOLVED] why 3 key in the same time doesn't work

Newbie & Debugging Questions
#1

hello,
am facing a little problem here,
i have a square that move with arrow key (up = forward, down = backward, left & right = +/- angle )
and shoot with Space key
the thing is that if for example i want to move forward,rotate left and shoot in the same time, it just doesn’t work, it only take the 2 first pressed key (in this case up & left) and ignore the Space key

here is the lines in the Board class about the keyListener (please tell me if you need the full class )


private boolean moveForward, moveBackward, left, right, fire;
-
-
addKeyListener(new Controll());
-
-
fire = left = right = moveForward = moveBackward = false;
-
-
-
// check if shooting
		if (fire) {
			hero.fire(10, 3);
		}

		// moving the hero
		if (moveForward) {

			hero.moveForward(speed);
		}
		if (moveBackward) {
			hero.moveBackword(speed);
		}

		if (left) {
			tmpAngle -= 1;
		}
		if (right) {
			tmpAngle += 1;
		}
-

-
// game key controll
	private class Controll extends KeyAdapter {

		public void keyPressed(KeyEvent e) {

			if (e.getKeyCode() == e.VK_UP) {
				moveForward = true;
			}
			if (e.getKeyCode() == e.VK_DOWN) {
				moveBackward = true;
			}
			if (e.getKeyCode() == e.VK_LEFT) {
				left = true;
			}
			if (e.getKeyCode() == e.VK_RIGHT) {
				right = true;
			}
			if (e.getKeyCode() == e.VK_SPACE) {
				fire = true;
			}

		}

		public void keyReleased(KeyEvent e) {

			if (e.getKeyCode() == e.VK_UP) {
				moveForward = false;
			}
			if (e.getKeyCode() == e.VK_DOWN) {
				moveBackward = false;
			}
			if (e.getKeyCode() == e.VK_LEFT) {

				left = false;
			}
			if (e.getKeyCode() == e.VK_RIGHT) {
				right = false;
			}
			if (e.getKeyCode() == e.VK_SPACE) {
				fire = false;
			}
		}
	}

thank you

I think this kind of problem usually has to do with the internal wiring of the keyboard.

#3

sooo it can’t be fixed :-\ ???

#4

I dont think there is much you can do, I was told ‘get creative with buttons’


Bit more info there perhaps

@JESTERRRRRR
thank you, that “solved” the problem
am using “Shift” instead of “Space”
