IwGame Engine v0.281 Released – Box2D Fixes

We found a couple of mistakes in the Box2D integration in  IwGame 0.28, so here is the fixed version, changes include:

  • Actor / scene Box2D implementation switched from multi-inheritence to composition
  • Bug Fix – Fixed issue with incorrect actor orientation when placed under Box2D control
  • bug Fix – Values for velocity, angular velocity etc were not being applied in XOML

You shouldn’t need to change any of your game code with this update.

    Hi Mat, couple of issues…

    1) Can you post an image or video of the sample application, because my new sample application is not behaving like the others usually do. Just adds the stripes once you click they do not have their usual random movement.

    2) Sound issue is still present, first click there is no sound, so I am guessing there need to be some initialization done or this could be a Marmalade issue.

    I’ve inserted a screen shot from into the post.

    Will take a look into the audio issue tomorrow.

    If you edit data\Audio.group and change vol 0.7 to vol 1 then it fixes the issue. Not sure what is causing the issue for lower values however

    Yeah that is weird issue…

    Ok from the screenshot i can’t see if you are having the same issue that I am. If you click the 10 sprite images don’t move, they simply fade… is anyone else having the same issue?

    When I change the Surface in the simulator from Iphone to Ipad, the objects fall down extremely slowly. I believe I need to change the WorldScale since the size of the screen changed, but I couldn’t get a good value to make it work. Has anyone seen this issue?
