This is the movement of the random robot, if it hits the wall (*), the line or colune should return to the previous value, right? Since I'm incrementing and decrementing if it happens, basically it checks if it's a wall or not.
It keeps doing the loop till the "S", turns into a "R". R is the robot S is the exit.
int linha = 1, coluna = 1;
while (labirinto[7][7] != "R") {
int aleatorio = randomGenerator.nextInt(4);
System.out.println(aleatorio);
switch(aleatorio)
{
case 0://cima
if(labirinto[linha--][coluna] == "*")
{
linha++;
break;
}
else labirinto[linha][coluna] = "R";
break;
case 1:
if(labirinto[linha++][coluna] == "*")
{
linha--;
break;
}
else labirinto[linha][coluna] = "R";
break;
case 2:
if(labirinto[linha][coluna++] == "*")
{
coluna--;
break;
}
else labirinto[linha][coluna] = "R";
break;
case 3:
if(labirinto[linha][coluna--] == "*")
{
coluna++;
break;
}
else labirinto[linha][coluna] = "R";
break;
}
imprimirLabirinto(labirinto);
}
}
This method just prints the updated maze.
static void imprimirLabirinto(String[][] labirinto) {
for (int i = 0; i < labirinto.length; i++) {
for (int j = 0; j < labirinto[i].length; j++) {
System.out.print(labirinto[i][j] + " ");
}
System.out.println();
}
System.out.println("\n");
}
The issue I don't understand is why it keeps going out of bounds, with the validations I got in the switch, why does it keep going to the wall. Also if I increment the variables in the else statement, it doubles the movement, which shouldn't happen since it doesn't hit a wall right?
