## [NPC] Walking help...

Okay so I have a walk method that randomly walks up down left and right but only move to one tile? How would i make it walk say 10 tiles without it spawning to 10 tiles...

Npc class
Java Code:
```package org.npc;

import java.awt.Image;
import java.util.Random;

import javax.swing.ImageIcon;

public class Npc {

Image npc;
final ImageIcon frontIcon = new ImageIcon(System.getProperty("user.home") + "/Desktop/GAME/NPC/HOME_FRONT.png");
final ImageIcon backIcon = new ImageIcon(System.getProperty("user.home") + "/Desktop/GAME/NPC/HOME_BACK.png");
final ImageIcon rightIcon = new ImageIcon(System.getProperty("user.home") + "/Desktop/GAME/NPC/HOME_RIGHT.png");
final ImageIcon leftIcon = new ImageIcon(System.getProperty("user.home") + "/Desktop/GAME/NPC/HOME_LEFT.png");

int action = 1;

int x, y;

int dx = 0;
int dy = y;

public Npc() {
x = 230;
y = 187;
npc = state();
}

public Image state() {
if (action == 1) {
return frontIcon.getImage();
} else if (action == 2) {
return backIcon.getImage();
} else if (action == 3) {
return rightIcon.getImage();
} else if (action == 4) {
return leftIcon.getImage();
}
return npc;
}

public int getX() {
return x;
}

public int getY() {
return y;
}

public void move() {
x += dx;
y += dy;
}

public void walk() {
Random rand = new Random();
int r = rand.nextInt(201);
if (r <= 25) {
for(int x = 0 ; x < 10 ; x++) {
walkUp();
}
} else if (r <= 50) {
for(int x = 0 ; x < 10 ; x++) {
walkDown();
}
} else if (r <= 75) {
for(int x = 0 ; x < 10 ; x++) {
walkLeft();
}
} else if (r <= 100) {
for(int x = 0 ; x < 10 ; x++) {
walkRight();
}
} else if (r <= 200) {
for(int x = 0 ; x < 10 ; x++) {
rest();
}
}
System.out.println("Random #=" + r);
}

public void walkUp() {
action = 2;
dy = -1;
}

public void walkDown() {
action = 1;
dy = 1;
}

public void walkRight() {
action = 3;
dx = 1;
}

public void walkLeft() {
action = 4;
dx = -1;
}

public void rest() {
dx = 0;
dy = 0;
}

}```
Please post anything that could help fix this bug and some code if you could would really help. Thanks
