I’m not sure that it’s possible at all, but I’m often using “named instances” in room editor (giving them custom name instead of inst_XXXXXX with random 8-digit HEX).
However when using them with GMLive, I’m getting:
Runtime error: [error]
instance#100083(obj_xxx)
(obj_xxx) does not have a variableinst_my_custom_name
Is it possible to add this feature ?
