Functions

_FallbackCall

__fcmbase._FallbackCall(self, method_name, fallback_value)

View source

Checks the existence of a class method before calling it. If the method exists, it returns as expected. If the method does not exist, it returns the fallback_value. This function allows a script to call a method that does not exist in earlier versions of Lua (specifically, in JW Lua) and get a default return value in that case.

@ additional_parameters (…) The additional parameters of the method.

Input	Type	Description
`self`	`userdata`	The class instance on which to call the method.
`method_name`	`string`	The name of the method to return.
`fallback_value`	`any`	The value that will be returned if the method does not exist. If this value is `nil`, the function returns `self`.
