Move objects in a rectangular pattern with easing functions from the Tween extension.

It can be used for:

  • Moveable platforms
  • Enemy movement patterns
  • Moving along the border of another object (inside, center, outside)

The platformer example uses this extension (open the project online).

This game shows how to make objects move around the border of another object (open the project online).

This example can be used to test different settings (open the project online).
