Make objects orbit around a center object

Make objects orbit around a center object in a circular or elliptical shape.

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

Run the actions on every frame to make the orbiting objects move. The extension will automatically create/delete orbiting objects to match the quantity specified. Use the delete function or set the quantity to 0 to remove all orbiting objects.

The elliptical orbit action can be used to create a 3D effect by changing the z-order of orbiting objects.

The customizable parameters include:

  • Center object
  • Orbiting object (must be different than the Center object)
  • Quantity of orbiting objects
  • Distance from the center object
  • Speed of the orbiting objects (in degrees per second). Use negative numbers to orbit counter-clockwise.
  • Speed to rotate each orbiting object (in degrees per second). Use negative numbers to rotate counter-clockwise.

Example uses:

  • Make shield objects around the player to protect from enemies
  • Weapons that can damage enemies when they collide
  • A visual indicator of ammo quantity or health points
  • Interesting animations of stacked objects that can function as a single entity
  • Visual cue for an active character power-up, such as invincibility

An example shows how to use this extension (open the project online).
