LUA code can explicitly request that a variable be saved by calling the [[API RegisterForSave|RegisterForSave("varName")]] function with the variable name that should be saved. That variable then becomes flagged for saving at the end of the session. It's important to note that since this is an active process, the variable will only be saved if it is registered during a session, so compilation execution failures that prevent the call from being made will end up without the variable being flagged. | LUA code can explicitly request that a variable be saved by calling the [[API RegisterForSave|RegisterForSave("varName")]] function with the variable name that should be saved.
