Ground Cancel Jump

From Jak Speedruns Wiki
Jump to navigation Jump to search

A ground cancel jump is a jump that does not update Jak's last known grounded position.

Ground cancel jumps are used to store fall damage and to initiate the infinite bounces needed for the current method of Fire Canyon Skip.

Technical

When Jak lands back on the ground from a jump or from loading a save file, it takes 3 frames of being grounded for the game to update Jak's last known grounded position. By jumping during this 3 frame window, Jak will go airborne again and his position will not be updated. These jumps can be chained to move Jak without updating his last known grounded position. By doing this, the game thinks that Jak is continuously airborne.

Discovery

The ground cancel jump was discovered by Kuitar.
