# 

# This example demonstrates how to create a dynamic shader definition 

# with 2 input parameters. Before adding the input parameters, a 

# ShaderParamDefOptions object is created, populated, and then

# passed into the ShaderParamDefContainer.AddParamDef method.

#

from win32com.client import constants as cns

app = Application

oShaderDef = XSIFactory.CreateShaderDef("MyParserName", "MyDynamicShader", 1, 0)

oShaderDef.AddShaderFamily("mrTexture")

app.LogMessage("Shader definition name: " + oShaderDef.Name)

# Set up shader parameter definition options to use with the first input parameter

oShaderInParamDefOptions = XSIFactory.CreateShaderParamDefOptions()

oShaderInParamDefOptions.SetAnimatable(False)

oShaderInParamDefOptions.SetTexturable(True)

oShaderInParamDefOptions.SetReadOnly(False)

oShaderInParamDefOptions.SetInspectable(True)

oShaderInParamDefOptions.SetShortName("Main Port")

# Add input array parameter to definition

oInputParams = oShaderDef.InputParamDefs

oInputParams.AddParamDef("main", cns.siColorParameterType, oShaderInParamDefOptions)

# You can use the same parameter definition options and just modify what you need

oShaderInParamDefOptions.SetAnimatable(True)

oShaderInParamDefOptions.SetShortName("Secondary Port")

oInputParams.AddParamDef("secondary", cns.siShaderDataTypeBoolean, oShaderInParamDefOptions)

# Now print out the info

app.LogMessage("Number of parameter(s) found: " + str(oInputParams.Definitions.Count))

for oShaderParamDef in oInputParams.Definitions :

	app.LogMessage("\t" + oShaderParamDef.DisplayName)

# INFO : Shader definition name: MyParserName.MyDynamicShader.1.0
