Launch rocket with countdown and acceleration in stdout is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
- Task Description
The task is to simulate the countdown of a rocket launch from 5 down to 0 seconds and then display the moving, accelerating rocket on the standard output device as a simple ASCII art animation.
Rust
<lang rust> use std::{thread, time};
fn print_rocket(above: u32) { print!( " oo
oooo oooo oooo
"); for _num in 1..above+1 {
println!(" ||");
} }
fn main() {
// counting
for number in (1..6).rev() {
print!("\x1B[2J");
println!("{} =>", number);
print_rocket(0);
let dur = time::Duration::from_millis(1000);
thread::sleep(dur); }
// ignition
print!("\x1B[2J");
println!("Liftoff !");
print_rocket(1);
let dur = time::Duration::from_millis(1000);
thread::sleep(dur);
// liftoff
let mut dur_time : u64 = 1000;
for number in 2..100 {
print!("\x1B[2J");
print_rocket(number);
let dur = time::Duration::from_millis(dur_time);
thread::sleep(dur);
dur_time -= if dur_time >= 30 {30} else {dur_time};
}
}
</lang>
