Trying to scroll world in my platform game - breaks the hitTestPoint code

[Moynzy]

Hello As3 wizards

I'm making a game and my current code muddles up my collision.

        container = new Sprite();

        addChild(container);

        container.addChild(ground);

        container.addChild(character);

        container.x = -character.x + stage.stageWidth / 2;

if your hittest is done correctly (ie, checking a hit between ground and character) there shouldn't be a problem because of changes to their parent's (container) x property.

HitTest has been done properly, because with out the scroll, hitTest works fine

               if (ground.bottom.hitTestPoint(character.x + 13, character.y, true || ground.bottom.hitTestPoint(character.x - 13, character.y, true)))
               {
                    while (ground.bottom.hitTestPoint(character.x + 13, character.y, true || ground.bottom.hitTestPoint(character.x - 13, character.y, true)))
                    {
                         character.incrementUp();
                         if (ground.bottom.hitTestPoint(character.x + 13, character.y, true || ground.bottom.hitTestPoint(character.x - 13, character.y, true)))
                         {
                         }
                         else{
                              character.keepOnGround();
                         }
                    }
               }
          }

Thank you.

that's the problem. bottom is not added directly to container.

alternatively you can check a hittestobject between character and ground.bottom

I think I know the problem!

Will I need to use the localToGlobal function?
