[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");
