If you want your character to stay the same scale size while exiting the scene, you have to make them walk to a spot somewhere offscreen. To make them exit while running, you have to add “and CHARACTER does it while run_animation” on the same line as the walking command.
Example:
@CHARACTER walks to spot 0.95 230 100 in zone 2 in 2 and CHARACTER does it while run_athletic_neutral_loop
