Are there commands for jump height/fall damage?

jump height I think would be controlled by player.setscale, with 1 being the default (for example, a wood elf is like .97, but a high elf is 1.03 or something, small changes have a big impact)

tgm would also reduce fall damage 100%, lol

Lol setscale also changes your characters model size which is undesirable
and tgm is undesirable for a number of reason.
