Save and export

To save The Scene as a project file, hit Ctrl-S or the respective button in the toolbar. This will save a Json file that can later be loaded by the editor again.

To export as a python script that can directly be used in projects, either hit Ctrl-E or click the button in the toolbar.

Use exported scripts

The python script will always contain a class called Scene which you can pass a NodePath to be used as root parent element for the scene. Simply instancing the class will load and show the scene by default. If this is not desired, hide the root NodePath as given on initialization. As you shouldn't edit the exported class due to edits being overwritten with a new export, you should create another python module which will handle the logic for the scene. This dedicated module could for example implement a show and hide method to easily change the visibility of the scene. All objects can be accessed from the instantiated scene by their name with special characters being replaced with an underscore.

Here is a small example of how to load and instantiate a Scene. We expect the scene to be exported to a file called myScene.py and contain a model named panda:

from myScene import Scene as MyScene
myScene = MyScene()
myScene.panda.set_pos(0,0,0)
