Interface: LayerProperties

LayerProperties is a MixinInterface providing access to a specific layer's properties.

This interface is returned by some methods in the Interface: LayerManager core interface and the Interface: INodeLayerProperties node interface.

    

Interface: LayerProperties

Properties: 

<LayerProperties>.on : boolean : Read|Write

Get/Set the Enabled state of the layer.

    

<LayerProperties>.lock : boolean : Read|Write

Get/Set the Locked state of the layer.

<LayerProperties>.INodeGIProperties : Interface : Read

The INodeGIProperties property returns a INodeGIProperties FPS interface giving access to the GI properties of the layer. See Interface: INodeGIProperties

    

<LayerProperties>.layerAsRefTarg : RefTarget : Read

Returns the layer as a ReferenceTarget.

NOTE:

The layer system operates exactly the opposite of what you would expect - the nodes reference the layer, rather than the layers referencing the node.

EXAMPLE 

s=sphere() --Create a sphere, store in variable
--> $Sphere:Sphere01 @ [0.000000,0.000000,0.000000]
sphere() --Create another one
--> $Sphere:Sphere02 @ [0.000000,0.000000,0.000000]
layer = layermanager.getlayer 0 --get default Layer 0
--> <MixinInterface:LayerProperties>
layerRT = layer.layerAsRefTarg --get layer as RefTarget
--> ReferenceTarget:BaseLayer
refs.dependents layerRT --see the dependents
--> #($Sphere:Sphere02 @ [0.0,0.0,0.0], $Sphere:Sphere01 @[0.0,0.0,0.0], ReferenceTarget:Animatable, ReferenceTarget:Animatable, ReferenceTarget:LayerManager, ReferenceTarget:Scene)
refs.dependson s
--> #(Controller:Position_Rotation_Scale, Sphere, ReferenceTarget:BaseLayer)

   

Methods: 

<void>addnode <node>node

Adds the given node to the layer. See bottom of page for an example.

    

<void>select <boolean>OnOff

If the Boolean value is passed as true, selects all objects on the layer in the scene. If the argument is passed as false, deselects all objects on the layer.

    

<boolean>setname <string>name

Sets the name of the layer to the given string. Returns true on success.

NOTE:

Layer names must be unique, which is why a method is used to set the layer name- it can validate the supplied name before assigning it to the layer as shown in the following example.

EXAMPLE 

--First reset 3ds Max to start in an empty scene, then execute:
layer1= layermanager.getlayer 0 --get default Layer 0
--> <MixinInterface:LayerProperties>
 
layer1.setName "The One" --try to change the name
--> false --you cannot, the default layer is always called "0"
 
layer2= layermanager.getlayer 1 --try to get Layer 1
--> undefined --there is no such layer yet.
 
layer2= layermanager.newLayerFromName "Test" --let's create it
--> <MixinInterface:LayerProperties>
 
layer2.setName "Second Layer" --now we can rename it
--> true
 
layer3= layermanager.newLayerFromName "Third" -- create another
--> <MixinInterface:LayerProperties>
 
layer3.setName "Second Layer" --try to give the same name as 2nd
--> false
 
layer3.setName "ThirdLayer" --it needs a unique name to work
--> true

    

<boolean>nodes <&node array>layerNodes

layerNodes is Out parameter

Returns True on success, and an array of all nodes on the layer in the by-reference Out parameter.

EXAMPLE 

layer = layermanager.newLayerFromName "Spheres"
--> <MixinInterface:LayerProperties>
 
for i =1 to 10 do (s = sphere(); layer.addNode s)
--> OK
 
layer.nodes &theNodes
--> true
 
theNodes
--> #($Sphere:Sphere10 @ [0.000000,0.000000,0.000000], $Sphere:Sphere09 @ [0.000000,0.000000,0.000000], $Sphere:Sphere08 @ [0.000000,0.000000,0.000000], $Sphere:Sphere07 @ [0.000000,0.000000,0.000000], $Sphere:Sphere06 @ [0.000000,0.000000,0.000000], $Sphere:Sphere05 @ [0.000000,0.000000,0.000000], $Sphere:Sphere04 @ [0.000000,0.000000,0.000000], $Sphere:Sphere03 @ [0.000000,0.000000,0.000000], $Sphere:Sphere02 @ [0.000000,0.000000,0.000000], $Sphere:Sphere01 @ [0.000000,0.000000,0.000000])
