<brief_description>
Reference to a function in an object.
</brief_description>
<description>
In GDScript, functions are not [i]first-class objects[/i]. 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 [method @GDScript.funcref] function, a reference to a function in a given object can be created, passed around and called.

<methods>
<method name="call_func" qualifiers="vararg">
<return type="Variant" />
<description>
Calls the referenced function previously set in [member function] or [method @GDScript.funcref].
</description>
</method>
<method name="call_funcv">
<return type="Variant" />
<argument index="0" name="arg_array" type="Array" />
<description>
Calls the referenced function previously set in [member function] or [method @GDScript.funcref]. Contrarily to [method call_func], this method does not support a variable number of arguments but expects all parameters to be passed via a single [Array].
</description>
</method>
<method name="is_valid" qualifiers="const">
<return type="bool" />
<description>
Returns whether the object still exists and has the function assigned.
</description>
</method>
<method name="set_instance">
<return type="void" />
<argument index="0" name="instance" type="Object" />
<description>
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].

<members>
<member name="function" type="String" setter="set_function" getter="get_function" default="""">
