   Hi guys

   I've not had this issue before, but since upgrading XCode and Cocos2D. I noticed this when creating a blank Box2D Project. Can't embed a screenshot, so I'll best explain.

   The world box is at bottom left but only a portion showing and the A B C D images are being displayed as one sprite ie:

   AB
   CD

   and not individual as I would expect. Also the DEBUG Draw box is not around the sprite where I would expect it, it's below by about 100 pixels. Wish I could attach a screen shot to help, but I can't sorry.

   Like I said I just created a blank Box2d project, and ran it to see the boxes when I tapped the screen.. by the way the Tap Screen message is top centre as expected. I've tried running in Retina and non-retina. Same issue for both runs expect the sprites are drawing as expected from the sprite sheet as individual A B C D sprite and not just one sheet with all four as per above.

   Hope this helps??

   I've had a bit of a play with this and here's my issue. Note: I had no issues with Cocos2D 0.99.x or previous SH and LH versions.

   I however updated to Cocos2d 1.1-rco and LevelHelper 1.4.9 and 1.8 Spritehelper.

   When I create my level and a new cocos2d box2d project. Screen is 320x480 retina (using iphone 4) and ios 6.x

   My screen displays with my sprites looking ok, but the debugdraw for box2d displays oddly, basically its shrunk to half the size. Although my sprites look ok, and my labels. Any other objects added to the levelscene are treated in the same way. Is this a problem with GLESDebugDraw. Or as I suspect is there something I'm missing since I've updated my software?

   Seems like a few methods aren't adjusted for retina. I'll look into it, thanks for trying RC0 out.

   Just tried it out on the simulator and a iPhone5. The boxes and debug draw lines display correctly. How did you update your code?

   There is a issue with the gravity, it doesn't work correctly on the device (gravity expects landscape, but default orientation is portrait).

   Hi Araker

   When I install my Cocos2d templates, I use the standard ./install-template.sh -f -u option.

   It seems I was missing something I've not had to use before in the draw() method, glScale??

   -(void) draw
   {

   glDisable(GL_TEXTURE_2D);
   glDisableClientState(GL_COLOR_ARRAY);
   glDisableClientState(GL_TEXTURE_COORD_ARRAY);

   //Seems I need to set glScale
   glPushMatrix();
   glScalef( CC_CONTENT_SCALE_FACTOR(), CC_CONTENT_SCALE_FACTOR(), 1.0f);
   world->DrawDebugData();
   glPopMatrix();

   // restore default GL states
   glEnable(GL_TEXTURE_2D);
   glEnableClientState(GL_COLOR_ARRAY);
   glEnableClientState(GL_TEXTURE_COORD_ARRAY);

   }

   Everything's working fine now. Back to converting my Project.

   Thanks again and keep up the good work guys!

   Normally the vertices are multiplied by CC_CONTENT_SCALE_FACTOR() (so you don't need to scale), but I don't see it in the code.

   I'll add it to my to-do list.
