//! Multi-turtle example demonstrating multiple independent turtles drawing simultaneously
|
|
//!
|
|
//! This example shows how to:
|
|
//! - Create multiple turtle instances using `add_turtle()`
|
|
//! - Control each turtle independently with separate command queues
|
|
//! - Position turtles at different locations using `go_to()`
|
|
//! - Use different colors and pen widths for each turtle
|
|
//! - Combine all turtle animations in a single rendering loop
|
