    i want to thank you for your effort but i puling the triger on the idea .

    its a work around the box2d prismatic joint which C2 does not support and cocoojs also.

    thanks again for your time and help <img src="smileys/smiley1.gif" border="0" align="middle" /> .

  • hello my android game work on launcher fine no error but when i compile the APK using ludei cloud service and install it in the device it's stuck at the ludei logo and flickrs.

    i tried a simple project just 2 sprite with physics and drag behaviors the same problem

    please help .

    its works fine in the launcher and it run at 60fps on my android 4 tablet but the APK does not work .any suggestion

    does any one had a similar probleme

    first thanks you very much for your time to set up an example for me realy appreciate it <img src="smileys/smiley20.gif" border="0" align="middle" />

    second i want to ask How could i limit the spring movement at certain angle example it move only in 45 degres

    i just could not find the formula <img src="smileys/smiley11.gif" border="0" align="middle" />.

    when i set the "spring_angle" to constant it became out of control.

  • hello everybody i need your help i want to make a spring using physics i am not looking to fake it just a simple spring

    any help or suggestion is more than welcome <img src="smileys/smiley1.gif" border="0" align="middle" />

    Hello everybody hope you are alright <img src="smileys/smiley1.gif" border="0" align="middle" />

    I want to ask for a clean simple explanation

    how can i implement this simple java-script example into C2

    example link :

  • I don't think the native physics engine does yet.

    first thank you <img src="smileys/smiley1.gif" border="0" align="middle" />

    hope they will suport it soooon <img src="smileys/smiley19.gif" border="0" align="middle" />

    spongehammer yes it will be nice

  • hello a simple question Does CocoonJS support prismatic joint ??<img src="smileys/smiley5.gif" border="0" align="middle" />

    thanks

  • Excal

    thank you

    how can i achieve that and also it's not a single sprite as the picture show its a car so two wheel sprite + 2 axel+ the body +2 trigger(just testing)
