When i play it, the input "J" and "I" have no problems but the problems was found when the input "K" and "L".
Anyone can help me fix the bug, thx a lots !!
Here is the code:
package javaapplication1;
import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{
Scanner Input = new Scanner (System.in);
System.out.println("Sokoban"+"\n1.Start Game"+"\n2.Top Score"+"\n3.Setting"+"\n4.Help"+"\n5.Exit");
boolean Terminated = true;
while(Terminated == true)
{
System.out.print("Please enter the function you choose: ");
int Project = Input.nextInt();
if (Project == 1)
StartGame();
else if (Project == 2)
TopScore();
else if (Project == 3)
Setting();
else if (Project == 4)
Help();
else if (Project == 5)
Terminated = Exit();
}
}
public static void StartGame()
{
Scanner Input = new Scanner (System.in);
System.out.print("Choose the level you want: ");
int LevelWanted = Input.nextInt();
char [][] Start = ChooseLevel(LevelWanted);
PrintMaze(Start);
GamePlay(Start, LevelWanted);
}
