Box2D Map Collision

[Slyth2727]

I would like to have a way to make maps in a map editor (tiled) and be able to add box2d collision detection to it. I have already seen Aurelion Ribon's program, however that doesn't seem to work with large map images. Is there a simple way to do this? If not, is there anyway you would suggest it? While looking around, I found that you can export a an xml file, so I was thinking that maybe in runtime I make my program look at the tiles and if the id equals one that is collidable add a box2d body around it? This is a topdown game as well. Anything helps! Thanks, -cMp

Define a box2d body for each map tile.

>Uses the outdated map api but everything else is the same.

That's what I was thinking, but would it cause performance or memory issues due to the large number of tiles on the map?

I doubt it, as long as the bodies are static.

I manage to do that yesterday with this:

1   2   3   4   5   6   7   8   9   10   11   12   13   14   15   16   17   18   19   20   21   22   23   24   25   26   27   28   29   30   31   32   33   34   35   36

BodyDef def = new BodyDef();       PolygonShape shape = new PolygonShape();       int current_body = 0;       for (MapObject object : mapa.getLayers().get(1).getObjects()) {          if (object instanceof RectangleMapObject) {             Rectangle rect = ((RectangleMapObject) object).getRectangle();             shape.setAsBox((rect.width / 2) / 10, (rect.height / 2) / 10);             def.position.x = (rect.x / 10) + ((rect.width / 10) / 2);             def.position.y = (rect.y / 10) + ((rect.height / 10) / 2);             cuerpos.add(world.createBody(def));             cuerpos.get(current_body).createFixture(shape, 1);          }          else if (object instanceof PolygonMapObject) {             Polygon poly = ((PolygonMapObject) object).getPolygon();             float vertices[] = poly.getTransformedVertices();             for (int x = 0; x < vertices.length; x++) {                vertices[x] /= 10;             }             System.out.println(vertices[0]);             shape.set(vertices);             def.position.x = poly.getOriginX() / 10;             def.position.y = poly.getOriginY() / 10;             cuerpos.add(world.createBody(def));             cuerpos.get(current_body).createFixture(shape, 1);          }          current_body++;       }

This code works only for rectangles and polygons but if think a bit you will be able to make it ellipse and polyline friendly

Probably a bit too late but whatever: this (this)

It's not too late , thank you very much for that, you've been really helpful!
