# Red Button example Contribution by Griatch, 2011 A red button that you can press to have an effect. This is a more advanced example object with its own functionality and state tracking. Create the button with create/drop button:contrib.tutorials.red_button.RedButton Note that you must drop the button before you can see its messages! It's imperative that you press the red button. You know you want to. Use `del button` to destroy/stop the button when you are done playing. ## Technical The button's functionality is controlled by CmdSets that gets added and removed depending on the 'state' the button is in. - Lid-closed state: In this state the button is covered by a glass cover and trying to 'push' it will fail. You can 'nudge', 'smash' or 'open' the lid. - Lid-open state: In this state the lid is open but will close again after a certain time. Using 'push' now will press the button and trigger the Blind-state. - Blind-state: In this mode you are blinded by a bright flash. This will affect your normal commands like 'look' and help until the blindness wears off after a certain time. Timers are handled by persistent delays on the button. These are examples of `evennia.utils.utils.delay` calls that wait a certain time before calling a method - such as when closing the lid and un-blinding a character. ---- This document page is generated from `evennia/contrib/tutorials/red_button/README.md`.
