FuncRef
Reference to a function in an object.
Description
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 @GDScript.funcref function, a reference to a function in a given object can be created, passed around and called.

Method Descriptions
Variant call_func ( ... ) vararg
Calls the referenced function previously set in function or @GDScript.funcref.
Variant call_funcv ( Array arg_array )
Calls the referenced function previously set in function or @GDScript.funcref. Contrarily to call_func, this method does not support a variable number of arguments but expects all parameters to be passed via a single Array.
bool is_valid ( ) const
Returns whether the object still exists and has the function assigned.
void set_instance ( 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, Vector2 or Dictionary.
