Trigger an event on map exit?

[greay]

Is there a way to trigger an event on map exit? Ideally this would be universal – there's a little thing I'd like to do every time a player switches to a new area.

Does MV have common events? Then you won't need a plugin. Just make a common event that does whatever you'd like to happen on map change, and Call Common Event after the transfer command in each map transfer event.

That's a lot of extra work to have to add that to every single place there's a map transfer event which makes my programmer brain cry. It violates the DRY principle ("Don't Repeat Yourself").


Sure, it would work (but begging for potentially sneaky bugs if I happen to miss an event somewhere). There Has To Be A Better Way.

How about this?


alias_Game_Interpreter_command201 = Game_Interpreter.prototype.command201;
Game_Interpreter.prototype.command201 = function () {
$gameTemp.reserveCommonEvent(1);
alias_Game_Interpreter_command201.call(this);
};


Runs whenever you use the Transfer Player event command. Change 1 to the id of the common event.


Edit: Here's a version where it the common event is only called when the next map is not the same:

    alias_Game_Interpreter_command201 = Game_Interpreter.prototype.command201;
    Game_Interpreter.prototype.command201 = function () {
        if (this._params[1] !== $gameMap.mapId()) {
            $gameTemp.reserveCommonEvent(1);
        }

        alias_Game_Interpreter_command201.call(this);
    };

command ... 201? 


that certainly looks like exactly what I need, thank you, there is no way I would have ever found that on my own. It's getting late, so I'm probably not going to get this working tomorrow, but I'm gonna trust you & call this solved.

It's just the transfer player command. I edited my post but here's a better solution for you again so you see it, it checks if the command is transferring the player to a new map instead of just another location in the current


alias_Game_Interpreter_command201 = Game_Interpreter.prototype.command201;
Game_Interpreter.prototype.command201 = function () {
if (this._params[1] !== $gameMap.mapId()) {
$gameTemp.reserveCommonEvent(1);
}

alias_Game_Interpreter_command201.call(this);
};



I've tested it and it works.
