How to Jump is an activated item.
Effects
- Upon use, Isaac jumps in the direction he is currently moving. The distance of the jump depends on how fast Isaac was moving when the item was activated. Jumping allows Isaac to travel over obstacles such as rocks, pits, and spikes.
- While mid-jump, enemies, enemy shots, bombs, and spikes cannot damage Isaac. Isaac cannot interact with pickups or chests mid-jump.
Notes
- If Isaac has flight, Isaac dashes instead of jumping. This is functionally the same as jumping, but without the animation playing. Isaac will have invincibility during the dash, and the dash will only stop on terrain that can be walked on.
- If Isaac has flight and is flying above a pit, the dash distance will be very short.
- The item can be used to jump through the pillars of light spawned by Isaac (Boss) without taking damage.
Interactions
Car Battery: How To Jump is unaffected by double activation.
