Input devices

There is singleton KB for keyboard and MOUSE for mouse device.

Simple input devices event handling:

KB.addListener(object: IKeyListener {
	override fun keyDown(keycode: Int) {
		if (keycode == KB.SPACE) println("Space pressed")
		println("key pressed: $keycode")
	}
	
	override fun keyUp(keycode: Int) {
		println("key released: $keycode")
	}
})

MOUSE.addListener(object: IMouseListener {
	override fun buttonDown(button: Int, screenX: Int, screenY: Int, pointer: Int) {
		println("button pressed: $button")
	}
	
	override fun moved(screenX: Int, screenY: Int) {
		println("mouse moved: $screenX, $screenY")
	}
})

Here we know when button was pressed/released or mouse moved.

We can check current state of input devices:

// in main loop
if (KB.isKeyPressed(KB.SPACE)) println("Space is pressed")

if (KB.shift) println("Shift is pressed")

println("mouse coords: (${MOUSE.x}, ${MOUSE.y})")
