libGDX change tilemap

问题

I am making an 2d rpg game with box2d. So, I've got a problem. When one of my bodies(the character) collides with another(a door) the map needs to change, should I just create new screens for maps and change them? Or is there a more simple solution?

回答1:

You can change your current map on the same screen only. What you have to do is, Let's say your map variable name is testMap. Now let's say your player just collided with a door. Now let's say you will call a method called changeMap(). Here is what you will put inside changeMap() method. (Assuming you are using tiled maps, you can change logic accordingly here)

void changeMap() {
    Gdx.app.postRunnable(() -> { //Post runnable posts the below task in opengl thread
        testMap = new TmxMapLoader().load("someMap.tmx"); //load the new map
        renderer.getMap().dispose(); //dispose the old map
        renderer.setMap(testMap); //set the map in your renderer
    });
}
