function LevelX:init() -- tnt virtual pad listeners self.vPad:addEventListener(PAD.LEFTPAD_EVENT, self.onVKeyDown, self) self.vPad:addEventListener(PAD.BUTTON1_EVENT, self.vShoot, self) end

function LevelX:onVKeyDown(event) print(event.data.power) print(event.data.angle) end

function LevelX:vShoot(event) if event.data.state == PAD.STATE_BEGIN then --local missile = Missiles.new(self.player.posx, self.player.posy - 12) end end </source>
