Advanced platformer movements

Let platformer characters: air jump, wall jump wall sliding, coyote time and dashing.

Authors and contributors to this experimental extension: D8H, shadow00dev, Entropy, CorianderGames.


This extension provides behaviors to:

  • Jump in mid-air
  • Jump and slide against walls
  • Dash horizontally
  • Dash toward the floor
  • Do coyote time, also known as "ledge tolerance". It lets players jumping even after their character is no longer touching the ground for a given amount of time. It aims to give players a feeling of control and reduce frustration.

An example allows to check it out (open the project online).
