Java - 2d Array Tile Map Collision
- by Corey
How would I go about making certain tiles in my array collide with my player? Like say I want every number 2 in the array to collide. I am reading my array from a txt file if that matters and I am using the slick2d library.
Here is my code if needed.
public class Tiles {
Image[] tiles = new Image[3];
int[][] map = new int[500][500];
Image grass, dirt, mound;
SpriteSheet tileSheet;
int tileWidth = 32;
int tileHeight = 32;
public void init() throws IOException, SlickException {
tileSheet = new SpriteSheet("assets/tiles.png", tileWidth, tileHeight);
grass = tileSheet.getSprite(0, 0);
dirt = tileSheet.getSprite(7, 7);
mound = tileSheet.getSprite(2, 6);
tiles[0] = grass;
tiles[1] = dirt;
tiles[2] = mound;
int x=0, y=0;
BufferedReader in = new BufferedReader(new FileReader("assets/map.txt"));
String line;
while ((line = in.readLine()) != null) {
String[] values = line.split(",");
for (String str : values) {
int str_int = Integer.parseInt(str);
map[x][y]=str_int;
//System.out.print(map[x][y] + " ");
y=y+1;
}
//System.out.println("");
x=x+1;
y = 0;
}
in.close();
}
public void update() {
}
public void render(GameContainer gc) {
for(int x = 0; x < 50; x++) {
for(int y = 0; y < 50; y ++) {
int textureIndex = map[y][x];
Image texture = tiles[textureIndex];
texture.draw(x*tileWidth,y*tileHeight);
}
}
}
}
I tried something like this, but I it doesn't ever "collide". X and y are my player position.
if (tiles.map[(int)x/32][(int)y/32] == 2)
{
System.out.println("Collided");
}
