[英]LibGDX TiledMap - don't detect Collisions
首先,对不起,因为我的英语不好。 自从我学德语以来,我就忘记了英语。
我正在使用libGDX进行测试,我的代码未检测到任何冲突。
在我的屏幕上:
public Pantalla(SpriteBatch batch_1) {
batch = batch_1;
screenWidth = Gdx.graphics.getWidth();
screenHeight = Gdx.graphics.getHeight();
stage = new Stage(new StretchViewport(Gdx.graphics.getWidth(), Gdx.graphics.getHeight()),batch);
Gdx.input.setInputProcessor(stage);
camera = new OrthographicCamera();
camera.setToOrtho(false, 1000, 840);
camera.update();
mapas = new Mapas(camera);
// ACTORS
indiana_actor = new indiana_Actor();
//Here comes TOUCHPAD with Skin blaBlaBla...
if (touchpad.isTouched()) {
if (touchpad.getKnobX() > 120) {
indiana_actor.moveBy(32,0);
camera.translate(32, 0);
return; }
}
stage.addActor(indiana_actor);
stage.addActor(touchpad);
Gdx.input.setInputProcessor(stage);
}
public void render(float delta) {//TODO RENDER
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
mapas.MapasRender(camera,indiana_actor);
batch.begin();
batch.end();
stage.act(Gdx.graphics.getDeltaTime());
stage.draw();
}
indiana_actor类别:
public indiana_Actor() {
W=Gdx.graphics.getWidth(); H=Gdx.graphics.getHeight();
bounds=new Rectangle((int)getX(), (int)getY(), (int)getWidth(), (int)getHeight());
}
Animation anim_temp;
@Override
public void draw(Batch batch, float parentAlpha) {
stateTime += Gdx.graphics.getDeltaTime();
batch.setColor(getColor());
batch.draw(Assets.indiana_stop_arriba, (W/2), (H/2), 110, 160);
bounds=new Rectangle((int)getX(), (int)getY(), (int)getWidth(), (int)getHeight());
}
和Mapas类。 在这些类中,我在“ objetos” TiledLayer中获得对象,并尝试在渲染器中使用for(...)检查冲突。
public Mapas(OrthographicCamera camera2){
map = new TmxMapLoader().load("terrain/prueba.tmx");
renderer = new OrthogonalTiledMapRenderer(map, 10);//ESCALA
renderer.setView(camera2);
collisionObjects = map.getLayers().get("objetos").getObjects();
collisionRects = new Array<Rectangle>();
collisionRects_total=collisionObjects.getCount();
int tileWidth = 32; // whatever your tile width is
int tileHeight = 32; // whatever your tile height is
for (int i = 0; i < collisionObjects.getCount(); i++) {
RectangleMapObject obj = (RectangleMapObject) collisionObjects.get(i);
Rectangle rect = obj.getRectangle();
collisionRects.add(new Rectangle(rect.x / tileWidth, rect.y / tileHeight, rect.width / tileWidth, rect.height / tileHeight));
}
}
public void MapasRender(OrthographicCamera camera2,indiana_Actor indi){
camera2.update();
renderer.setView(camera2);
renderer.render();
for (int i = 0; i < collisionRects_total; i++) {
Rectangle rect = collisionRects.get(i);
if (indi.bounds.overlaps(rect)){
Gdx.app.log("EVENTO", "MAPAS RENDER - COLISION!");
}if (rect.overlaps(indi.bounds)){
Gdx.app.log("EVENTO", "MAPAS RENDER - COLISION!");
}
}
}
我知道(通过logcat)“ for(int i = 0; i <crashRects_total; i ++){Rectangle rect = crashRects.get(i);“总是得到objectsRectangle,但是在下一行中发现任何重叠。
那是actor bounds-rectangle的问题吗?在通过地图移动actor时有问题吗?
提前致谢!!
为什么不首先检查您的碰撞矩形是否正确绘制在位置上。 您可以致电
shapeRenderer.begin(ShapeType.Line);
shapeRenderer.setColor(Color.NAVY);
shapeRenderer.rect(object.getrect().x,
object.getrect().y,object.getrect().width,
object.getrect().height);
可能是您在错误的位置绘制了碰撞矩形,因此永远不会发生碰撞。
