Can anyone guide me the way to do a jump on P2? I have read this article about the jump on P2 http://www.html5gamedevs.com/topic/6148-the-moving-jumpthrough-platform-sum-up-thread-help-very-much-appreciated/, but what I actually wanted is that: I want to jump depend on how I press the key : example: if I press slightly, it will jump a little and if I press hardly, it will jump high. please give me a demo. Thanks you for helping.
