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. </description> <tutorials> </tutorials> <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].
