Platformer trajectory

Platformer character jump easy configuration and platformer AI tools.

Authors and contributors to this community extension: D8H.


This extension allows to:

  • Configure the height of a jump by automatically choosing the right jump speed (open the project online).
  • Know when to jump to reach a platform (can be useful for AI).
  • Draw jump trajectories to check a level design.

Tip

Learn how to install new extensions by following a step-by-step guide.

Platformer trajectory evaluator

Configure the height of a jump and evaluate the jump trajectory.

Behavior actions

Draw jump
Draw the jump trajectories from no sustain to full sustain.

Jump height
Change the jump speed to reach a given height.
