## Basic usage ## Basic usage
For using **Druid**, first you should create Druid instance to spawn components. Pass to new Druid instance main engine functions: *update*, *on_message* and *on_input* To use **Druid**, first you should create a Druid instance to spawn components and add Druids main engine functions: *update*, *final*, *on_message* and *on_input*.
All **Druid** components as arguments can apply node name string, you can don't do `gui.get_node()` before All **Druid** components take node name string as arguments, don't do `gui.get_node()` before.
All **Druid** and component methods calling with `:` like `self.druid:new_button()` All **Druid** and component methods are called with `:` like `self.druid:new_button()`.
