Is there anyway I can change the distance in a Sp replay in notepad?

If so can someone tell me how

You can change the engage distance in notepad.

NEWGAME 1;120 10 15 0 0 3 100 0 0 classic 0 0 100 0 0 0 1 0 2 0 0 0 0 0 0 0.000000 0.000000 -9.820000 0 0

The 100 in bold is the engage distance. Simply edit that value to alter the distance.

But if its for a replay you have already made then it wont work.

Best way to change the gamerules is in the game rules menu. Press ctrl + g to get it.

Yeah it was a replay I already made :/

Well every time you submit a move, the position of your joints is recorded. So changing the engage distance only works for the frames before your first move(generally 0 frames) Then your player will jump to the positions that were in the replay before you edited it in notepad.
