Reference to a function in an object.
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.
|Variant||call_func ( ... ) vararg|
|Variant||call_funcv ( Array arg_array )|
|bool||is_valid ( ) const|
|void||set_function ( String name )|
|void||set_instance ( Object instance )|
Calls the referenced function previously set by set_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.
Returns whether the object still exists and has the function assigned.
The name of the referenced function to call on the object, without parentheses or any parameters.
