Yes, the title isn't very good. Let me explain.
In my hangman game, I want to add a bonus that indicates the time you have to print a letter. The time is set to 10sec. The problem is that I'm having trouble displaying the remaining time in real time on the terminal (like Time remaining 10s, Time remaining 9s ect (with time.sleep ect)) and asking the user for their opinion. So I used mouse cursor movement to move from line 0 to line 1 and get user input while displaying time remaining. The funny thing is that I don't know how to make a proper user input that allows the user to print a letter and not instantly exit the program after a user input. If you don't understand what I'm saying, I can try to explain it again.

Here is my actual CODE :
package main
import (
"fmt"
"os"
"time"
"golang.org/x/term"
)
func main() {
done := make(chan bool)
go waitForInput(done)
startTime := time.Now()
duration := 10 * time.Second
ticker := time.NewTicker(500 * time.Millisecond)
isTimeRemaining := true
for {
select {
case <-ticker.C:
if isTimeRemaining {
elapsed := time.Since(startTime)
remaining := duration - elapsed
if remaining <= 0 {
remaining = 0
os.Exit(0)
}
moveCursorToLine(0)
fmt.Printf("\033[2K\rTemps restant: %s", remaining.Round(time.Second))
} else {
moveCursorToLine(1)
fmt.Printf("\033[2K\rEntrez quelque chose: ")
}
isTimeRemaining = !isTimeRemaining
case <-done:
ticker.Stop()
fmt.Println("\nSaisie utilisateur détectée.")
return
case <-time.After(duration):
ticker.Stop()
fmt.Println("\nTemps écoulé sans saisie.")
return
}
}
}
func waitForInput(done chan<- bool) {
oldState, err := term.MakeRaw(int(os.Stdin.Fd()))
if err != nil {
fmt.Println("Impossible de passer en mode raw:", err)
return
}
defer term.Restore(int(os.Stdin.Fd()), oldState)
var buf [1]byte
for {
_, err := os.Stdin.Read(buf[:])
if err != nil {
fmt.Println("Erreur de lecture de l'entrée:", err)
return
}
done <- true
break
}
}
func moveCursorToLine(line int) {
fmt.Printf("\033[%d;0H", line+1)
}
