The Project Lister displays all game objects in the level and sublevels. The directory tree shows the game object’s grouping and hierarchy, as shown in the figure below.
When you open a new level, the Project Lister contains a single folder. The Game Objects folder contains all game objects in the level. Sublevel folders are shown in folders at the same hierarchy level as the Game Objects folder.
To open the Project Lister, select the Window > Project Lister menu item.
A checkmark appears next to the Project Lister item in the Window menu and the Project Lister becomes frontmost.
When the Project Lister is open, but not frontmost, you can click its tab to make it visible.
To close the Project Lister, select the Window > Project Lister menu item again.
No checkmark appears next to the Project Lister item in the Window menu and the Project Lister is hidden.
