first of all, sorry, because of my rusty English. Since i learnt German i forgot the English.
I'm doing tests with libGDX and my code doesn't detect any collisions.
In my Screen:
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 Class:
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());
}
and Mapas Class. In these class i get the Objects in the "objetos" TiledLayer, and triying to check collisions with a for(...) in the renderer.
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!");
}
}
}
I know (Through the logcat) that the " for (int i = 0; i < collisionRects_total; i++) { Rectangle rect = collisionRects.get(i); " get always the objectsRectangle , but in the next line find any overlaps.
Is that a problem with the actor bounds-rectangle?A problem when moving actor through the map??....
Thanks in advance!!
Why dont U at first check if your rectangle for collision draw correctly on position. You can do that by calling
shapeRenderer.begin(ShapeType.Line);
shapeRenderer.setColor(Color.NAVY);
shapeRenderer.rect(object.getrect().x,
object.getrect().y,object.getrect().width,
object.getrect().height);
may be you draw collision rectangles at wrong position so collision will never occur.
