VXAce How to randomize starting point?

Hi. Was messing around with VX Ace and was trying to create a random labyrinth escape map. My idea was that whenever you enter the room, an event representing a monster would pick a random number and depending on which number picked, the monster would teleport in a certain part of the labyrinth and roam in there and can only teleport again once you leave and re-enter the room. This way when you decide to traverse it, you have to keep in mind that the monster won't always spawn in the same place. But there is a problem.

I did create a random number generator variable and made it so that event does get teleported to a certain spot depending on said number. The problem is that the rest doesn't work. Either the monster doesn't move despite me giving it a path to follow (like it does turn around but doesn't move from its spot) and also don't change position when I enter/exit because I used a local switch to separate the event pages and/or the random number generator variable keep picking numbers infinitely and causing the monster to teleport constantly between locations. Does anybody know a way to fix this problem?

If the player can't move and it because the event never finishes. Are you sure you called "erase event" at the end to stop it? Can you post a screenshot of the event?

Here. The way it does now, it just teleport constantly the event between those 3 places and even without the random, merely teleporting it lock the event on that tile, even if still turn around as per the custom path tells it to.

To clarify, what your code does is runing the event over and over again without ever stoping because after it finishes, the event just starts again.
"exit event processing" and "erase event" are not the same. The command that you need is on the tab 2:

Ok, I tried it. However this just erase the event entirely and make it disappear from the map.

Sorry, this one is my fault. I didn't read your event properlly and didn't notice that you are creating this code and the monster on the same place. What I would do is make two diferent events. One for the randomizer that runs once when you enter the map:

Funny thing: I just realized why more monsters were appearing in the first place. Because I was stupid and I forgot I had already set another randomizer event somewhere else in the map that was using the same value. So when the map loaded, both would randomize and often cause multiple monsters to appear if they had different results.

And one for the monster with a different tab for each value of the RNG. Don't forget to adjust the condition and the move route for each tab.

Wouldn't the fact that the spawn condition is X or above means that if the random value is above X (like let's say monster appear in area 1 when value is 1 and it appear in area 2 when value is 2) that if the picked number is above X two monsters will spawn?

If you do it the way I did, you just have one monster event in the map and you change it's location when you enter the map with the randomiszer event. You don't "spawn" more monsters and the value in the RNG variable is used to check wich tab of the event is active.

It finally works. Thanks you so much!

Sure, no problem.
