Question

I have ArrayIndexOutOfBoundsException error in getTile function which is in the World class, my problem is that i cannot floor the background with background image, I cannot add other tiles i got empty window and these errors.

package com.game.Tiles;
import java.awt.Graphics;
import java.awt.image.BufferedImage;

public class Tile {
    // static stuff
    public static Tile[] tiles = new Tile[512];
    public static Tile background = new Background(0);
    public static Tile target = new Target(1);
    // class

    public static final int TILE_WIDTH = 50, TILE_HEIGHT = 50;
    protected BufferedImage texture;
    protected final int id;

    public Tile(BufferedImage texture, int id) {
        super();
        this.texture = texture;
        this.id = id;
        tiles[id] = this; // class ı tile a ekliyoruz yukardan gelen id ile
    }

    public void tick(){

    }
    public void render(Graphics graphic, int positionX, int positionY){
        graphic.drawImage(texture, positionX, positionY, TILE_WIDTH, TILE_HEIGHT, null);
    }

    public int getId() {
        return this.id;
    }
    public boolean isPasseble()
    {
        return false;
    }
}


package com.game.world;

import java.awt.Graphics;

import com.game.Tiles.Tile;

public class World {


    private int height, width;
    private int[][] tiles;

    public World(){
        this.loadWorld();

    }
    public void tick(){

    }
    public void render(Graphics graphic){
        for (int y = 0; y < this.height; y++) {
            for(int x = 0; y < this.width; x++){
                this.getTile(x, y).render(graphic, x * Tile.TILE_HEIGHT, y * Tile.TILE_WIDTH);
            }
        }
    }
    public Tile getTile(int x, int y){
        Tile t = Tile.tiles[this.tiles[x][y]];
        if(t == null)
            return Tile.background;

        return t;
    }
    private void loadWorld(){
        this.width = 30;
        this.height = 30;
        this.tiles = new int[this.width][this.height];
        for (int x = 0; x < this.width; x++) {
            for (int y = 0; y < this.height; y++) {
                this.tiles[x][y] = 0;
            }
        }

    }
}

Errors:

Answer 1

This line should

for(int x = 0; y < this.width; x++){

should be

for(int x = 0; x < this.width; x++){
