  Sorry for the slow reply and thank-you very much for posting that capx.

  I can see that you've added an additional test against the player's physics velocity being zero before setting it with the stored value. I can't really see why this is necessary (some quirk of the physics engine perhaps?) but I'm happy it's working.

  Thanks for the suggestion - I had already tried moving the events around but it didn't seem to have any effect.

  Hi,

  I want to be able to simulate the 'wrap' behaviour for an object that is being moved using a physics force. I understand that teleporting objects by changing their position directly can cause problems with the physics routines so I am trying the following approach:

  • when the object leaves the layout then

  - store its current physics velocity in instance variables

  - set its physics velocity to zero

  - teleport the object to the other side of the layout by setting its position

  • if the object has a stored physics velocity then

  - set its physics velocity to the stored value

  - set the stored value to zero

  The problem I have is that including the step in bold above causes the physics velocity to be set to zero after the object has been teleported for some reason. If I disable this step then the object gets the correct velocity following the teleport but the event will keep firing and restoring the stored value.

  Theres a simple capx showing my problem here.

  Is there any chance you could post your capx or the images again somewhere? I'm interested to see how you resolved this.

  Thanks.
