Ellipse movement

Move objects on ellipses or smoothly back and forth in one direction.

Authors and contributors to this experimental extension: 4ian, VictrisGames, D8H.

It allows objects to move:

  • on an ellipsis or arcs
  • smoothly vertically or horizontally (by setting one radius to 0)
  • on a sine wave (by adding a force)

Instances will start their movement from their initial position on the scene. The center position will be decided according to the "initial direction" angle and the radius.

It can be used for:

  • Making objects float, such as powerups or coins
  • Moving platforms
  • Enemy movement patterns
  • Making a player constantly turn right or left (open the project online)
