I found a hack I think the community should know.
Say, you allow the reader to customize their character, and you want to do a mirror scene. Everybody knows the long stressful coding it will take.
There is an easier way.
Say you decided to let the reader customize their character. MC, and you want to make a duplicate character, MCMIRROR. After the reader customizes the MC, place MCMIRROR offscreen, and put this command
@MCMIRROR becomes MC
This simple, one-line dialogue will solve all of your troubles. If you want to create a mother character, you could include hair and face changing lines afterward, like:
@MOM becomes MC
@MOM changes hair into Morning Updo
Hope this eased anyone’s struggles!
