Init (Command)


Description

Fired the first time a command is invoked after the plug-in is loaded. Specifies the return value and arguments of the command.

Unlike other commands in Softimage (both custom and native), self-installing custom commands are added to the Softimage command map when Softimage loads and removed when Softimage terminates (or when explicitly uninstalled). For this reason, self-installing commands must be defined inside the Init callback.

Syntax

public class <command_name>
{
        public bool Init( Context in_context )
        {
                ...
        }
}
CStatus <command_name>_Init( CRef& in_context ) 
{ 
        ... 
}
function <command_name>_Init( in_context ) 
{ 
        ... 
}
def <command_name>_Init( in_context ):
        ...
Function <command_name>_Init( in_context )
        ...
End Function
sub <command_name>_Init 
{ 
        my $in_context = shift; 
}

<command_name> is the name specified in the call to PluginRegistrar.RegisterCommand, with any spaces converted to underscores.


Parameters

Parameter Language Type Description
in_context Scripting and C# Context Context.Source returns the Command.
C++ CRef& A reference to the Context object. Context::GetSource returns the Command.
