This mode helps in debugging by displaying aspects that are usually hidden while in gameplay.
Open View > Toggle display mode to see the options that can be made visible. These can be used in editor mode and gameplay mode independently, which is useful when you’d like to show a lot of debug information while editing, but would like a clean screen during gameplay.
Let’s have an example to clear things up:
If we, for instance, wanted to show all the different trigger areas and waypoints used on our level, we would need to enable the right filters. For that, we need to go into Editor options > Debug and enable Areas and Waypoints. It should look something like this:
If you start gameplay in the world after that, you’d notice that the filters aren’t visible. This is because we did not apply these options in Game options > Debug.
Now you can debug easier, and test your debugs in peace.
