Here's random parts of an InputManager class I made.
First you need to find the keyboard and store it for future use.

| private static Keyboard findKeyboard()
{
for (int i = 0; i < controllers.length; i++)
if (controllers[i].getType() == Controller.Type.KEYBOARD)
return (Keyboard)controllers[i];
return null;
} |
In an initializer somewhere...
1
| keyboard = findKeyboard(); |
Then every timestep you want to poll the keyboard. This simply goes through all the buttons to find what has been pressed, putting it all in a giant boolean list.

| public static boolean[] pollKeyboard()
{
keyboard.poll();
Component[] c = keyboard.getComponents();
boolean[] b = new boolean[c.length];
for (int i = 0; i < c.length; i++)
{
if (c[i].getPollData() != 0)
b[i] = true;
else
b[i] = false;
}
return b;
} |
To use the above, you'd do this:
1
2
3
4
| if (pollKeyboard()[net.java.games.input.Component.Identifier.Key.A])
{
doA();
} |
Or if you just want to avoid a boolean list (better depending on what you want to do) you can do this:
1
2
3
4
| if ((keyboard.isKeyDown(net.java.games.input.Component.Identifier.Key.A))
{
doA();
} |
