FuncRef

Inherits: Reference < Object

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.

Methods

Variant	call_func ( ... ) vararg
Variant	call_funcv ( Array arg_array )
bool	is_valid ( ) const
void	set_function ( String name )
void	set_instance ( Object instance )

Method Descriptions

Variant call_func ( ... ) vararg

Calls the referenced function previously set by set_function or @GDScript.funcref.

Variant call_funcv ( Array arg_array )

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.

bool is_valid ( ) const

Returns whether the object still exists and has the function assigned.

void set_function ( String name )

The name of the referenced function to call on the object, without parentheses or any parameters.

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.
