3D 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)

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)
