not sure if you want something to do with events, but imo you can do almost anything with the events...I dont have rpg maker open so this is what I would assume would work:
map: event turn menu access off.
common event:
Conditional branch: Button input: _
- Turn menu access on
- change actor graphic (to faceset, but put faceset in the charset folder.)
- show menu
commen event:
conditional branch: actor graphic ___ (faceset)
- Conditional branch
- Button input (make this to close the menu)
- Change actor graphic (normal char set graphic)
- Change menu access off.
sorry if it doesn't work.
