"Tracer bounds backward in time, returning her health, ammo and position on the map to precisely where they were a few seconds before."
Tracer's recall video
So, the only thing usable in rpg maker is the ability to recover health, because there's no position on map nor ammo. This is how the ability description in my game is:
"The user goes back to the previous turn and regains the life that had at the beginning of that turn."
How can I achieve this?
