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.
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()
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.
