# Path Creation

There are two ways to create a path in valora.

### Immediate

You could use draw commands on the canvas which immediately result in the path, but the path can only be drawn and not held for mutation or other work. 

```rust
canvas.move_to(P2::new(430., 225.));
canvas.line_to(P2::new(83., 225.));
canvas.line_to(P2::new(256., 525.));
canvas.close_path();
canvas.set_stroke_width(2.);
canvas.stroke();
```

### Held

Alternatively, you could use some types provided by valora to define the path in a way you can hold, mutate, and otherwise do work with. For example, this code which repeats the triangle scaling down each time:

```rust
let triangle = Ngon::triangle(world.center(), 200.);
let repeated = std::iter::successors(Some(triangle), |t| {
    Some(t.clone().scale(0.9))
});

for triangle in repeated.take(15) {
    canvas.paint(Stroked {
        width: 2.,
        element: triangle,
    });
}
```

Valora provides [Ngon](https://docs.rs/valora/0.2.0/valora/forms/struct.Ngon.html) for equilateral shapes, [Ellipse](https://docs.rs/valora/0.2.0/valora/forms/struct.Ellipse.html) for ellipses, and [Polygon](https://docs.rs/valora/0.2.0/valora/forms/struct.Polygon.html) for all other shapes.
