CustomProperty.AddParameterFromDef

Introduced

v5.0

Description

Creates a Parameter from a ParamDef object. ParamDef objects contain the definition of a parameter from which you can create new parameters on the fly for one or more property sets or operators. For example, you may want to use a double with the same min/max range and use it on multiple property sets or you may simply want a quick way to add parameters to a runtime scripted operator via scripting. You can create New ParamDef objects from the XSIFactory object.

Scripting Syntax

oReturn = CustomProperty.AddParameterFromDef( ParamDef );

Return Value

The newly created Parameter object.

Parameters

Parameter Type Description
ParamDef ParamDef New parameter definition

JScript Example

/*
        This example illustrates how to create parameters from a parameter definition.

var o = ActiveSceneRoot.AddCustomProperty("MyProperty");

var param2 = o.AddParameterFromDef(XSIFactory.CreateParamDef2("bool", siBool, true));
