如何制作.tmx地图填满整个屏幕
我正在使用Libgdx加载.tmx地图，地图没有填满整个屏幕。我无法弄清楚问题，所以作为最后的手段，我在这里问一个问题。我正在关注YouTube上的教程，他没有解决这个问题，因此我无法继续。我尝试了多项没有成功的事情。地图宽度：240个瓷砖，高度：13个瓷砖，瓷砖是16乘16
，
这是代码。我认为这个问题与

我相信你要找的是将相机夹到地图上的能力。 这可以使用MathUtils.clamp实现。
gameCam.position.x = MathUtils.clamp(gameCam.position.x, viewportWidth/2 , 38 - viewportWidth/2);
gameCam.position.y = MathUtils.clamp(gameCam.position.y, viewportHeight/2, 208 - viewportHeight/2);

问题在于相机的放置，附带相机的相机以使相机的视口覆盖整个屏幕。我想解决这个问题。
public float gokuStartingPositionX;
public PlayScreen(DBZ game){
.....
new B2WorldCreator(world,map);
gokuStartingPositionX=64/DBZ.PPM; //added in your method
player = new Goku(world, this);
}
public void update(float dt){
handleInput(dt);
world.step(1/60f, 6, 2);
player.update(dt);
//camera position is decided by player position and keep camera in this way so it cover whole viewport width with screen
gameCam.position.x = player.b2body.getPosition().x + gamePort.getWorldWidth()/2 - gokuStartingPositionX;
gameCam.update();
renderer.setView(gameCam);
}
悟空中的小修改
public Goku(World world, PlayScreen screen){
super(screen.getAtlas().findRegion("goku_sprite"));
this.world = world;
defineGoku(screen.gokuStartingPositionX);
gokuStand = new TextureRegion(getTexture(), 5,12,59,85);
setBounds(0,0,59/DBZ.PPM,85/DBZ.PPM);
setRegion(gokuStand);
}
public void defineGoku(float startX){
BodyDef bdef = new BodyDef();
bdef.position.set(startX,32/DBZ.PPM);
bdef.type = BodyDef.BodyType.DynamicBody;
b2body = world.createBody(bdef);
...
}
