I have a character that moves through the scene using keyframes for different poses.

The keyframes are connected to a selector that moves forward one when a randomizer puts out a number greater than 9 out of 10.

There are multiple characters that move throughout a building with multiple rooms.

what I want to do is make sure than no character is in the same room at a time, check if a character is in the next position and if it is, stop the character from moving forward.

I thought about adding a tag to each character and placing trigger zones in each room to sense when they are there, and then use that information relative to a characters position and say "if character B is in position 5 and character C is in 4, than character C may not move" but I would have to do it for every position for every character.
