## 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

    ' ports, and seeing what target they drive.

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

    i = 1
    for each oPort in oLayer.TextureLayerPorts
            logmessage "Port " & i & " drives: " & oPort.Target
            i = i + 1
