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
FuncRefusing the GD.Funcref(Godot.Object, string) function, a reference to a function in a given object can be created, passed around and called.
public object CallFunc(params object args)
public void SetFunction(string name)
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.
