Teleport object when it moves off the screen and immediately appear on the opposite side while maintaining speed and trajectory.

Authors and contributors to this community extension: Entropy, VictrisGames.

The teleport happens when the center point of the object crosses a border. Change behavior properties to increase or decrease the margin used to trigger this teleport. By default, the borders of the wrapping area match the screen size, but they can alo be changed.

The Asteroid-like example uses this extension (open the project online).
