An object representing a method in a certain object that can be called.
[Callable] is a first class object which can be held in variables and passed to functions. It represents a given method in an [Object], and is typically used for signal callbacks.

[gdscript]
var callable = Callable(self, "print_args")
func print_args(arg1, arg2, arg3 = ""):
prints(arg1, arg2, arg3)
func test():
callable.call("hello", "world") # Prints "hello world".
callable.call(Vector2.UP, 42, callable) # Prints "(0, -1) 42 Node(Node.gd)::print_args".
callable.call("invalid") # Invalid call, should have at least 2 arguments.
[/gdscript]
[csharp]
Callable callable = new Callable(this, "print_args");
public void PrintArgs(object arg1, object arg2, object arg3 = "")
{
GD.PrintS(arg1, arg2, arg3);
}
public void Test()
{
callable.Call("hello", "world"); // Prints "hello world".
callable.Call(Vector2.Up, 42, callable); // Prints "(0, -1) 42 Node(Node.gd)::print_args".
callable.Call("invalid"); // Invalid call, should have at least 2 arguments.
}

Constructs a null [Callable] with no object nor method bound.
Constructs a [Callable] as a copy of the given [Callable].
Creates a new [Callable] for the method called [code]method[/code] in the specified [code]object[/code].
Calls the method represented by this [Callable]. Arguments can be passed and should match the method's signature.
Calls the method represented by this [Callable] in deferred mode, i.e. during the idle frame. Arguments can be passed and should match the method's signature.
Returns the name of the method represented by this [Callable].
Returns the object on which this [Callable] is called.
Returns the ID of this [Callable]'s object (see [method Object.get_instance_id]).
