# ScriptCommandData

The **ScriptCommandData** object is passed to the script-defined entry points for any [internal commands](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/example_scripts/adding_a_new_internal_command) added by a [script add-in](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/script_add-ins). The method name for these events is defined by the script itself, but generically it's referred to as [**OnScriptCommand**](https://chaoses-ib.gitbook.io/directory-opus/manual/reference/scripting_reference/scripting_events/onscriptcommand).
