Thanks this is great for mazes, but I am looking more for open rooms and doors, (doors not necessary I suppose) not tunnels, but thanks a ton anyway, this will help me!
Why not make multiple different ones and use variables?
EXAMPLE: say you wanted it to have a random dungeon out of 2 different ones you have created.
Go to variable operations. Choose random Number between 1 and 2 (depending on how many dungeons you want it to randomize from)
<>Variable [0001] = Random (1,2)
Okay now Conditional branches. On tab 1 go to variable>constant>1>==
<>Conditional Branch Variable [0001] == 1
<>Teleport [001 YourDungeon1]
: :Else Handler
Then repeat what you just did except replace one with two in the conditional branch and change the teleport event to the other possible dungeon. Place this under else handler.
