J2ME飞机设计游戏,希望对学习J2ME的程序员有所帮助

public class SpeedCommand implements Command{
	public SpeedCommand(){
		planeActor = BattlePlaneActor.getInstance();
	}
	
	public void execute(int xPos, int yPos) {
		if (planeActor.getBattle_magic() >= 60) {
			planeActor.setAddSpeed(true);
			planeActor.setXSpeed(planeActor.getXSpeed() + 4);
			planeActor.setYSpeed(planeActor.getYSpeed() + 4);

			planeActor.setBattle_magic(planeActor.getBattle_magic() - 60);
		}
	}
