Current questions and answers regarding the map editor.

It opened the animation for me, but it doesn't display the properties I need. Specifically, I can't set the coordinates for the movement.

On the left, in the DialogScene tree, click on any folder, and then on the name of your scene. This should update the properties tree.
If the scene doesn't open and instead shows the map, double-click on the scene name in the tree on the left. The editor should start loading the scene.
