infinte loop detected . there is no loop , in a dungeon generator.

Solution: Use a while loop in the Event Graph.
That tutorial shows a lot of bad practices. Best suggestion would be to split code into separate functions, and use a while-loop instead of the loop he introduces.

Thanks for posting this, it helped me realize that I was not the only one. I both like and dislike this tutorial. It showed me a new way about thinking of PCG using collisions in an intuitive way, but introduces many bad practices. Especially when he does something and states “I don’t know why, I just did it like this and it worked.”

I’d suggest breaking the whole algorithm into logical functions.
For myself, I have the following:

  • Event Graph: Sets the seed, spawns the first room, starts the timer, then USING A WHILE LOOP, spawns new rooms until the room count has been reached
    My functions look like this:
  • Event Graph → Spawn New Room → Check For Overlap (& Get Overlapping Rooms)

Event Graph

Spawn New Room

Check For Overlap

Get Overlapping Rooms

I now go from 58 rooms generated (until infinite loop) to 1000+ with no infinite loop
