Reference to a function in an object.
    public class FuncRef : Reference

In GDScript, functions are not first-class objects. 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 GD.FuncRef(Godot.Object, string) function, a reference to a function in a given object can be created, passed around and called.

Constructors

    public FuncRef()

Methods

    public object CallFunc(params object[] args)

    public object CallFuncv(Godot.Collections.Array argArray)

Calls the referenced function previously set by SetFunction(string) or GD.FuncRef(Godot.Object, string). Contrarily to CallFunc(params object[]), this method does not support a variable number of arguments but expects all parameters to be passed via a single Array.

    public bool IsValid()

Returns whether the object still exists and has the function assigned.

    public void SetFunction(string name)

The name of the referenced function to call on the object, without parentheses or any parameters.

    public void SetInstance(Object instance)

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](https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/int], Vector2 or Dictionary.
