Reference to a function in an object. In GDScript, functions are not [i]first-class objects[/i]. This means it is impossible to store them directly as variables, return them from another function, or pass them as arguments. However, by creating a [FuncRef] using the [method @GDScript.funcref] function, a reference to a function in a given object can be created, passed around and called. Calls the referenced function previously set in [member function] or [method @GDScript.funcref]. Calls the referenced function previously set in [member function] or [method @GDScript.funcref]. Contrarily to [method call_func], this method does not support a variable number of arguments but expects all parameters to be passed via a single [Array]. Returns whether the object still exists and has the function assigned. The object containing the referenced function. This object must be of a type actually inheriting from [Object], not a built-in type such as [int], [Vector2] or [Dictionary]. The name of the referenced function.
