Any object you want to apply an action must be declared with getObject, e.g. if you try to translate an object without declaring it first, nothing will happen.
objectName: object name
To declare an object, simply put at the top of the script :
object = getObject("object")
To declare an object from another scene, include the scene as first argument :
scene2 = getScene("scene2") scene2object = getObject(scene2, "object")
You can also give it a different name :
CustomName = getObject("object")
Note: You must do the same for anything you want to apply a script. It includes Camera, Text, Meshes and Sounds.
