Sitting Removed: Finally! This fix/change has been requested by so many of you! So after some critical thinking, this has been fixed. Players will no longer sit down as if they were riding something during a jumppad launch. Players still won't be able to change direction or teleport during a launch. (However, they may slightly impact accuracy by holding a key down. Only by 2-3 blocks)
During this change, I noticed that the launch may actually have triggered twice. This has also been fixed. This may affect your jumppads launch distance by a few blocks.
New Preview:
Event change: The dismount event has been replaced by the entity damage event as it is no longer needed. The damage event cancels the fall damage received after a launch. Previously the damage cancellation was handled by the entity ridden.
