multiple key detection for KeyListener (java)

Question

How would one implement KeyListener so that I can create a two-player system where one person uses \'.\' and \'/\' to control a character, and the other person can use the arrow

Answer 1

Create a HashMap that marks which keys are currently pressed/depressed.

Then in your game loop, you can move your objects depending on if the keys are depressed in this map.

For example:

if (keyMap.get(VK_COLON) == Boolean.TRUE) //True indicates pressed
   playerAXPos+= 10;
