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 [code]FuncRef[/code] using the [method @GDScript.funcref] function, a reference to a function in a given object can be created, passed around and called. </description> <tutorials> </tutorials> <demos> </demos> <methods> <method name="call_func" qualifiers="vararg"> <return type="Variant"> </return> <description> Calls the referenced function previously set by [method set_function] or [method @GDScript.funcref]. </description> </method> <method name="set_function"> <return type="void"> </return> <argument index="0" name="name" type="String"> </argument> <description> The name of the referenced function to call on the object, without parentheses or any parameters. </description> </method> <method name="set_instance"> <return type="void"> </return> <argument index="0" name="instance" type="Object"> </argument> <description> The object containing the referenced function.
