Timeline can drive scripts by adding keyframes to an object at start and end with values equal to the first and last frames. Watchdog is used to read the keyed values. Same can be done to read the modelspace timeline.

popup panel – can get a panel frame by dragging an item out of the panel stack view. Set the RootNode connector value to the parent of the object that will be displayed. Set the Panel Node connector of the Panel Node to the node that will be floating. Copy into Windows Manager Space and run 2 mystery commands then set the panel aspect.

	WindowsManager.CloseWindow("Project/Windows Manager Space/TestPanelFrame")
	var rpf = Space.CurrentScene() + "/TestPanelFrame";

	Node.Value(rpf, "RootNode") = Space.CurrentScene();
	Node.Value(rpf + "/Panel Node", "PanelEditorNode") = Space.CurrentScene() + "/YafaRay IES Spot";
	Node.Copy(rpf, "/Project/Windows Manager Space");

Widgets.Rotate == rotate about origin (0,0,0) then offset back to original position

Node.Selection() – returns a selection list with a semicolon delimination, but has leading spaces in each nodes path so needs to be adjusted to work with Space.Select

sel = Node.Selection();
selArray = sel.split(";");
re = /^\s/; // whitespace in first character position
sel = selArray[0].replace(re,"");
if(selArray.length > 1)
        for(i=1;i<selArray.length;i++)
                sel = sel + ";" + selArray[i].replace(re,"");

Node.Select – select one node

Space.Unselect()

%THIS_OWNER_NAME%

%THIS_BUTTON_ITEM% – enables a toolbar button to see it’s full path

LE. – (L E dot) undocumented LE commands

Activity.Run(scene + “/second”);//runs after the calling script is done

ScriptObject.Execute(scene + “/second”);//runs immediately pausing the calling script

If you add a new connector to a script used inside the Widgets it won’t work right away. Restarting truespace will unstick it. 

//functions for generating random guid for marker display

matrix multiplication

   myMatrix.LoadIdentity();
   myMatrix.SetPitch(-90);// myMatrix = -90 deg pitch => last rotation
   myMatrix.Mult(rollMatrix);// rollMatrix (this is the second rotation) * myMatrix => myMatrix
   myMatrix.Mult(yawMatrix);// yawMatrix (this is the first rotation) * myMatrix => myMatrix
   final result in myMatrix is yaw then roll then pitch
Local matrix from world matrices
theMatrix = Node.Value(bindgroup + "/" + subNode, "WldMatrix");
parentMatrix = Node.Value(bindParent, "WldMatrix");
parInvert = parentMatrix.Invert();
theMatrix.Mult(parInvert);
//now theMatrix contains local instead of world

Space.Select() – select multiple nodes from text string separated by semi colons, node paths in the list must not have leading spaces

sel = Node.Selection();
selArray = sel.split(";");
re = /^\s/; // whitespace in first character position
sel = selArray[0].replace(re,"");
if(selArray.length > 1)
        for(i=1;i<selArray.length;i++)
                sel = sel + ";" + selArray[i].replace(re,"");
Node.Select – select one node
Space.Unselect()
	var strEnum = System.CreateDO("Common Data Package/String Enum Data");
