edit updated with better flags

Thank for the huge download, lol.

Unfortunately, with mouse clicks you can control which instance simply by which one was clicked. I need some other way to reference each individual one on its own. Like some sort of UID? I don't know.

You can add a dedicated instance var for it.

Give each flag a unique number in their var.

famflag.flagnumber

Event

Pick by evaluate famflag : famflag.flagnumber = 1

action

do something to famflag which has flagnumber 1
