Here's my
map class:
public class map{ public static final int CLEAR = 0;
public static final ArrayList<Integer> STONE = new ArrayList<Integer>();
public static final int GRASS = 2;
public static final int DIRT = 3;
public static final int WIDTH = 32;
public static final int HEIGHT = 24;
public static final int TILE_SIZE = 25;
// static int[][]
map = new int[WIDTH][HEIGHT];
ArrayList<ArrayList<Integer>>
map = new ArrayList<ArrayList<Integer>>(WIDTH * HEIGHT);
enum tiles {
air, grass, stone, dirt
}
Image air, grass, stone, dirt;
Random rand = new Random();
public Map() {
/* default
map */
/*for(int y = 0; y < WIDTH; y++){
map[y][y] = (rand.nextInt(2));
System.out.println(map[y][y]);
}*/
/*for (int y = 18; y < HEIGHT; y++) {
for (int x = 0; x < WIDTH; x++) {
map[x][y] = STONE;
}
}
for (int y = 18; y < 19; y++) {
for (int x = 0; x < WIDTH; x++) {
map[x][y] = GRASS;
}
}
for (int y = 19; y < 20; y++) {
for (int x = 0; x < WIDTH; x++) {
map[x][y] = DIRT;
}
}*/
for (int y = 0; y < HEIGHT; y++) {
for(int x = 0; x < WIDTH; x++){
map.set(x * WIDTH + y, STONE);
}
}
try {
init(null, null);
} catch (SlickException e) {
e.printStackTrace();
}
render(null, null, null);
}
public void init(GameContainer gc, StateBasedGame sbg) throws SlickException {
air = new Image("res/air.png");
grass = new Image("res/grass.png");
stone = new Image("res/stone.png");
dirt = new Image("res/dirt.png");
}
public void render(GameContainer gc, StateBasedGame sbg, Graphics g) {
for (int x = 0; x < WIDTH; x++) {
for (int y = 0; y < HEIGHT; y++) {
switch (map.get(x * WIDTH + y)) {
case CLEAR:
air.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
case STONE:
stone.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
case GRASS:
grass.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
case DIRT:
dirt.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
}
}
}
}
public static boolean blocked(float x, float y) {
return map[(int) x][(int) y] == STONE;
}
public static Rectangle blockBounds(int x, int y) {
return (new Rectangle(x, y, TILE_SIZE, TILE_SIZE));
}
}
Specifically I am looking at this:
for (int x = 0; x < WIDTH; x++) {
for (int y = 0; y < HEIGHT; y++) {
switch (map.get(x * WIDTH + y).intValue()) {
case CLEAR:
air.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
case STONE:
stone.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
case GRASS:
grass.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
case DIRT:
dirt.draw(x * TILE_SIZE, y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
break;
}
}
}
How can I access the coordinates of my arraylist
map and then draw the tiles to the screen?
Thanks!
