# Lecture step 1: get to know the game

![The game right after the language was chosen](https://git.tirsystem.com/Tirsvad-Udemy-100-days-of-code/048-the-coockie-factory-new/raw/branch/main/docs/images/step-1.png)

## What the assignment asks

Open the new version of Cookie Clicker (ozh.github.io/cookieclicker) and learn how it works before writing any code.

## What we found

We opened the page in a headless Chromium inside a Docker container and looked at its HTML. The parts the bot needs:

| What | Where on the page |
| --- | --- |
| English on the language selection | `#langSelect-EN` |
| The big cookie | `#bigCookie` |
| The cookie count and the cookies per second | `#cookies` (and `#cookiesPerSecond` inside it) |
| The store | `#products`, with `#product0` (Cursor), `#product1` (Grandma), `#product2` (Farm) and so on |
| A product's name and price | `.productName` and `.price` inside the product |
| Can I afford it? | the product has the class `unlocked enabled` (a product you cannot afford yet is `unlocked disabled`; a hidden one is `locked disabled`) |

Also good to know:

- The game asks for a language the first time the page loads. The bot must pick one by itself.
- The count is written as text: `3 cookies`, `5,000 cookies`, and for large numbers on two lines, `1.235` and `million cookies`.
- A cookie banner ("Got it!") sits at the bottom of the page. The bot never clicks it, because it is a consent banner that belongs to the person playing; the bot works around it (see [Step 4](Step-4-Five-Minute-Run)).

All of these ids and selectors are written once, in `constants.py`.

## What we gained in this step

- **Read the page before coding.** A short look at the real HTML saved hours of guessing; every selector in the bot came from this step.
- **Keep selectors in one place.** If the game changes an id, one line in `constants.py` is the fix.
- **Run the browser in a container.** The same Docker image that runs the bot takes the screenshots, so nothing opens on your own desktop and every run starts from the same clean browser.
