Crate turtle

The API Documentation below will help you learn about the various things you can do with this crate.

If this is your first time using Rust or using this crate, read the Guide on turtle.rs to learn how to start.

The documentation for the Turtle struct contains a listing of all of the various drawing commands that you can use on the Turtles that you create. The color module and its submodules contain hundreds of predefined color names that you can use to set the pen, background and fill color of a turtle. That module also explains how to use any arbitrary color, including ones that may not be defined in this crate.

Note: Call turtle::start() if you do not create a turtle with Turtle::new() right at the beginning of your program. Most programs will never need to call this function as it is called for you in Turtle::new().

Random Values

See the rand module for information about generating random colors, speeds, angles, and more which can be used in your programs to produce some interesting results!

Event Handling

The Event enum documentation provides information about how you can create an event loop. This allows you to draw things in response to certain events like the mouse moving, keys being pressed, and more.

The Turtle struct contains a few convenience methods so you can do some common event-related things without creating the entire event loop. For example, use wait_for_click() to wait for the user to click anywhere on the screen before proceeding.
