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 by [method set_function] or [method @GDScript.funcref].
Calls the referenced function previously set by [method set_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 name of the referenced function to call on the object, without parentheses or any parameters.
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].
