我使用 Tile 软件创建了 10 个对象图层，并使用 OrthogonalTiledMapRenderer 对象渲染了平铺地图。
renderer.setView(camera);
renderer.render();
我已经创建了将 Actor 类扩展到它的 backgroundTiledMap 类。在 mainGame 类的阶段添加 backgroundTiledMap 类的对象。它的渲染完美。
但是当我试图将下一个演员添加到同一个舞台时。它没有被渲染。
是否有任何不同的方式使用平铺地图和演员来检测两者之间的碰撞。
低于实际代码
backgroundTiledMap.java扩展为actor并用于从平铺地图中绘制背景的类（在平铺软件中创建）
public class BackgroundTiledMap extends Actor {
public MapProperties properties;
public MapLayer layer;
public MapObject mapObject;
public TiledMapTileLayer tiledLayer;
private TiledMap map;
private OrthogonalTiledMapRenderer renderer;
private OrthographicCamera camera;
public Array<Rectangle> tiles = new Array<Rectangle>();
private Pool<Rectangle> rectPool = new Pool<Rectangle>() {
@Override
protected Rectangle newObject () {
return new Rectangle();
}
};
GameStartPoint game;
Stage stage;
Reptile reptile;
public BackgroundTiledMap(GameStartPoint game,Stage stage)
{
this.game = game;
this.stage = stage;
init();
}
public void init()
{
map = new TmxMapLoader().load("Images/GuideCrocodile.tmx");
renderer = new OrthogonalTiledMapRenderer(map, 1 / 16f);
camera = new OrthographicCamera();
camera.setToOrtho(false, 70, 50);
camera.update();
stage.setCamera(camera);
}
@Override
public void draw(SpriteBatch batch, float parentAlpha) {
super.draw(batch, parentAlpha);
render();
}
public void render()
{
camera.update();
renderer.setView(camera);
renderer.render();
}
}
这是mainGame用于创建舞台的屏幕，所有其他演员和对象都在这里添加
public class GuideCrocodileScreen implements Screen {
public GameStartPoint game;
private Stage stage;
public BackgroundTiledMap backgroundTiledMap;
public Reptile reptile;
MoveToAction moveAction;
public GuideCrocodileScreen(GameStartPoint game)
{
this.game = game;
stage = new Stage();
}
@Override
public void render(float delta) {
// clear the screen
Gdx.gl.glClearColor(0.7f, 0.7f, 1.0f, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
Gdx.input.setInputProcessor(stage);
stage.draw();
}
private void addReptile(){
reptile = new Reptile(stage,100,100,50,50);
// backgroundTiledMap.getTiles(100,100,50,50);
reptile.addListener(new InputListener() {
public boolean touchDown (InputEvent event, float x, float y, int pointer, int button) {
System.out.println("down");
return true;
}
public void touchUp (InputEvent event, float x, float y, int pointer, int button) {
System.out.println("up");
}
public void touchDragged (float x, float y, int pointer) {
reptile.updateReptile(x,y);
}
public boolean touchMoved (float x, float y) {
//reptile.updateReptile(x,y);
return false;
}
});
stage.addActor(reptile);
}
@Override
public void resize(int width, int height) {
}
@Override
public void show() {
addBackgroundArea();
addReptile();
}
private void addBackgroundArea(){
backgroundTiledMap = new BackgroundTiledMap(game,stage);
stage.addActor(backgroundTiledMap);
}
}
新的演员类，这是演员在屏幕上移动，检测与在 backgroundTiledMap 上绘制的对象的碰撞 reptile.java（这没有被渲染）
public class Reptile extends Actor {
public GameStartPoint game;
private OrthogonalTiledMapRenderer renderer;
public SpriteBatch batch;
public int screenWidth;
public int screenHeight;
private Texture reptiletexture;
private TextureRegion reptileRegion;
private Stage stage;
public Reptile( Stage stage,int x, int y,int width, int height){
setX((float)x);
setY((float)y);
setWidth((float)width);
setHeight((float)height);
this.setTouchable(Touchable.enabled);
this.stage = stage;
initialize();
}
private void initialize(){
this.screenWidth = GameStartPoint.WIDTH;
this.screenHeight = GameStartPoint.HEIGHT;
reptiletexture = new Texture(Gdx.files.internal("Images/basketball.png"));
reptileRegion = new TextureRegion(reptiletexture);
this.setVisible(true);
}
@Override
public void draw(SpriteBatch batch,float parentAlpha)
{
super.draw(batch,parentAlpha);
batch.draw(reptileRegion, getX(), getY(), getOriginX(),
getOriginY(), getWidth(), getHeight(), getScaleX(),
getScaleY(), getRotation());
}
public void updateReptile(float x,float y)
{
int duration = 5;
if(Gdx.input.isTouched())
{
MoveToAction action = Actions.action(MoveToAction.class);
action.setPosition(x, y);
action.setDuration(duration);
this.addAction(action);
}
}
@Override
public Actor hit(float x, float y, boolean touchable) {
//Gdx.app.log("","reptile is touched.. ") ;
updateReptile(x,y);
return super.hit(x, y, touchable);
}
}
