Character Movement through rooms-

So the project I am working on is similar in concept to the locked room assassination mission from Elder Scrolls: Oblivion, where a small group of characters move from room to room in search of various objects. Some the player needs to avoid, others, the player may target for attacks, etc.

I'm finding that making this happen in RPG Maker isn't as easy as I'd hoped. My first solution was to have single objects in each room that could, according to a random number generator, become any of the characters, or no character, if that character had already been eliminated or the room happened to be empty. Running into problems with that, though, like the characters never becoming "solid" despite all my best efforts.

I guess I am wondering how other makers here might go about solving a similar problem. I suppose another way to do it would be to make the whole thing one big map and monitor movements, but room entry and exit had been, to this point, one of my regular event triggers.

So how would you do it?

'Game Mechanics Design' is for looking at aspects of game play at a more conceptual level. "How do I...?" (implementation) questions go in the Support forum for the engine you are using.

I have moved it to RPGMaker VX based on the information under your avatar. If, however, that information is incorrect, e.g. it should be VX Ace, please post and specify which it should be, and the thread can then be moved again.

Gotcha, sorry. And yes, I am currently using VX Ace. Thank you.

I've moved this thread to VXAce Support. Thank you.

Please edit your profile to reflect this then. Currently it says you use VX, instead of VXAce.

Yes, you can do that - but you need to show us Screenshots of an example of the events that don't work so that we can see how you made them and where your mistakes are.
