# Quickstart Examples

## Example #1: Drawing

We can draw a simple emoji onto the screen with Ovals. We will mimic: ":hushed:" with a gray background.

```python
from pydraw import *

screen = Screen(800, 600)
screen.color(Color('gray'))

face = Oval(screen, 100, 0, 600, 600, Color('yellow'))
face.wedges(40)

eye1 = Oval(screen, 200, 200, 85.71, 100)
eye2 = Oval(screen, 500, 200, 85.71, 100)

eyebrow1 = Rectangle(screen, 157.14, 150, 100, 5, rotation=-16)
eyebrow2 = Rectangle(screen, 517.85, 150, 100, 5, rotation=16)

mouth = Oval(screen, 350, 400, 85.71, face.height() / 109)

screen.stop()
```

{% hint style="info" %}
Note that we calculated those numbers using these formulas:

```python
eye1 = Oval(screen, face.x() + face.width() / 6, 200, face.width() / 7, face.height() / 6)
eye2 = Oval(screen, (face.x() + face.width()) - (face.width() / 6) * 2, 200, face.width() / 7, face.height() / 6)

eyebrow1 = Rectangle(screen, eye1.x() - eye1.width() / 2, 200 - 50, 100, 5, rotation=-16)
eyebrow2 = Rectangle(screen, eye2.x() - 25 + eye2.width() / 2, 200 - 50, 100, 5, rotation=16)
```

{% endhint %}

## Example #2: Animation

We can animate our face now by adding an animation loop and having our eyes blink every 3 seconds (note that we've now switched to the proportions-based calculations):

```python
from pydraw import *

screen = Screen(800, 600)
screen.color(Color('gray'))

face = Oval(screen, 100, 0, 600, 600, Color('yellow'))
face.wedges(40)

eye1 = Oval(screen, face.x() + face.width() / 6, 200, face.width() / 7, face.height() / 6)
eye2 = Oval(screen, (face.x() + face.width()) - (face.width() / 6) * 2, 200, face.width() / 7, face.height() / 6)

eyebrow1 = Rectangle(screen, eye1.x() - eye1.width() / 2, 200 - 50, 100, 5, rotation=-16)
eyebrow2 = Rectangle(screen, eye2.x() - 25 + eye2.width() / 2, 200 - 50, 100, 5, rotation=16)

mouth = Oval(screen, 400 - 50, 400, face.width() / 7, face.height() / 5.5)

count = 0
fps = 30
running = True
while running:
    seconds = count / fps

    if 1.9 < seconds < 2:
        eye1.height(1)
        eye2.height(1)
    if seconds >= 2.1:
        eye1.height(face.height() / 6)
        eye2.height(face.height() / 6)
        count = 0
    count += 1

    screen.update()
    screen.sleep(1 / fps)
```

{% hint style="info" %}
Notice how we replaced:

```python
screen.stop()
```

with *this* in order to create an animation loop:

```python
fps = 30
running = True
while running:
    screen.update()
    screen.sleep(1 / fps)
```

{% endhint %}

## Example #3: Input

Now we will move our emoji's mouth based on the mouse's position:

```python
from pydraw import *

screen = Screen(800, 600)
screen.color(Color('gray'))

face = Oval(screen, 100, 0, 600, 600, Color('yellow'))
face.wedges(40)

eye1 = Oval(screen, face.x() + face.width() / 6, 200, face.width() / 7, face.height() / 6)
eye2 = Oval(screen, (face.x() + face.width()) - (face.width() / 6) * 2, 200, face.width() / 7, face.height() / 6)

eyebrow1 = Rectangle(screen, eye1.x() - eye1.width() / 2, 200 - 50, 100, 5, rotation=-16)
eyebrow2 = Rectangle(screen, eye2.x() - 25 + eye2.width() / 2, 200 - 50, 100, 5, rotation=16)

mouth_default = Location(400 - 50, 400)
mouth = Oval(screen, 400 - 50, 400, face.width() / 7, face.height() / 5.5)

def mousemove(location):
    mouth.moveto(mouth_default.x() + (location.x() - mouth_default.x()) / 7,
                    mouth_default.y() + (location.y() - mouth_default.y()) / 7)

screen.listen()

count = 0
fps = 30
running = True
while running:
    seconds = count / fps

    if 1.9 < seconds < 2:
        eye1.height(1)
        eye2.height(1)
    if seconds >= 2.1:
        eye1.height(face.height() / 6)
        eye2.height(face.height() / 6)
        count = 0
    count += 1

    screen.update()
    screen.sleep(1 / fps)
```

![Example #3 Output](https://i.imgur.com/PouDHJe.gif)

{% hint style="info" %}
Notice how a new method was added:

```python
def mousemove(location):
    # code
```

And below that method we tell the screen to listen for input:

```python
screen.listen()
```

{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pydraw.graphics/guides/quickstart.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
