## TextureLayerPort.Target

### Introduced

v4.0

### Description

Returns the shader or material Parameter which this port drives.

### C# Syntax

    // get accessor

    Parameter rtn = TextureLayerPort.Target;

### Examples

#### 1. JScript Example

    // This example shows enumeration of texture layer

    // ports, and seeing what target they drive.

    oRoot = ActiveProject.ActiveScene.Root;

    oSph = oRoot.AddGeometry( "Sphere", "MeshSurface" );

    oMat = oSph.AddMaterial( "Phong" );

    oPhong = oMat.Shaders(0);

    oParam = oPhong.parameters( "specular" );

    oFractal = oParam.ConnectFromPreset( "Fractal", siTextureShaderFamily );

    // Add a layer at the end.

    oLayer = oPhong.CreateTextureLayer( "DirtLayer" );

    // Add some texture layer port connections on this layer.

    oPorts = new Array(3);

    oPorts[0] = oLayer.AddTextureLayerPort( oPhong.parameters( "ambient" ) );

    oPorts[1] = oLayer.AddTextureLayerPort( oPhong.parameters( "diffuse" ) );

    // The next line shows adding a port which is on a container that the layer

    // is currently not part of -- it will be added to that container.

    oPorts[2] = oLayer.AddTextureLayerPort( oFractal.parameters( "color1" ) );

    Application.LogMessage( "Created " + oLayer.TextureLayerPorts.count + " ports." );

    for ( i = 0; i < oLayer.TextureLayerPorts.count; i++ )

    {

    	oPort = oLayer.TextureLayerPorts(i);

    	Application.LogMessage( "Port " + (i+1) + " drives: " + oPort.Target );

    }

    // This example should log something like:

    //INFO : "Created 3 ports."

    //INFO : "Port 1 drives: sphere.Material.Phong.ambient"

    //INFO : "Port 2 drives: sphere.Material.Phong.diffuse"

    //INFO : "Port 3 drives: sphere.Material.Phong.Fractal.color1"

#### 2. VBScript Example

    ' This VB script example shows enumeration of texture layer

    ' ports, and seeing what target they drive.

    set oRoot = ActiveProject.ActiveScene.Root

    set oSph = oRoot.AddGeometry( "Sphere", "MeshSurface" )

    set oMat = oSph.AddMaterial( "Phong" )

    set oPhong = oMat.Shaders(0)

    set oParam = oPhong.parameters( "specular" )

    set oFractal = oParam.ConnectFromPreset( "Fractal", siTextureShaderFamily )

    ' Add a layer at the end.

    set oLayer = oPhong.CreateTextureLayer( "DirtLayer" )

    ' Add some texture layer port connections on this layer.

    dim oPorts(2)

    set oPorts(0) = oLayer.AddTextureLayerPort( oPhong.parameters( "ambient" ) )

    set oPorts(1) = oLayer.AddTextureLayerPort( oPhong.parameters( "diffuse" ) )

    ' The next line shows adding a port which is on a container that the layer

    ' is currently not part of -- it will be added to that container.

    set oPorts(2) = oLayer.AddTextureLayerPort( oFractal.parameters( "color1" ) )

    logmessage "Created " & oLayer.TextureLayerPorts.count & " ports."

    i = 1

    for each oPort in oLayer.TextureLayerPorts

    	logmessage "Port " & i & " drives: " & oPort.Target

    	i = i + 1

    next

    ' This example should log something like:

    'INFO : "Created 3 ports."

    'INFO : "Port 1 drives: sphere.Material.Phong.ambient"

    'INFO : "Port 2 drives: sphere.Material.Phong.diffuse"

    'INFO : "Port 3 drives: sphere.Material.Phong.Fractal.color1"
