engine.editor Functions
This set of functions is related to the Unigine Engine Editor that loads and manages the hierarchy of nodes displayed in the editor.
int engine.editor.addNode (Node node)

World space coordinates are used for this function.
Arguments
- vec3 p0 - Start point of the line.
- vec3 p1 - Destination point of the line.
- int exclude_id - Array of the objects to exclude; all these objects will be skipped while checking for intersection.
- int ret_id -
Return array, its components are:
- ret[0]: intersection point (vec3), in the world coordinates.

- ret[2]: surface number.
Return value
Reference to the first crossed object or NULL (0), if no object is crossed.Node engine.editor.getNodeByName (string name)
Returns a node (loaded from the *.world file or belonging to the node list of Unigine Editor) by its name.Arguments
