How does the dungeon tracker work?

Hi Stefan, I'm actually working on fixing a couple of the completion detection points, so you can probably just wait for the next version.

However, to answer your question, the X,Y,Z points are coordinates retrieved directly from the mumble interface. In addition to the end point, pre-req, and identifying points, there is another property called detection radius. A player is detected as reaching a point in a dungeon when they are within that radius of the point.

Endpoint is the point used to determine if a dungeon is completed. If the player is within the detection radius for an endpoint and the UI tick stops updating (meaning the player has entered a cutscene or loading screen), the dungeon is marked as completed. Additionally, all pre-req points must be reached before the endpoint detection counts. Identifying points are the points used to determine which explorable path the player is running.

Edit:
Can you add a debugtool or similiar (maybe for a beta version) to track coordinates while running a dungeon?
