我在使用LibGDX和Artemis框架实现平滑的慢动作渲染时遇到了麻烦。我知道如何更改“delta”以使其正常工作(使用这个),但我无法弄清楚如何在
我的Screen类:
Screen
接口的渲染方法中实际实现它。我该如何更改Screen
的渲染方法的delta参数以基本上减缓时间?我的Screen类:
public class GameScreen implements Screen {
private SpriteRenderSystem spriteRenderSystem;
private OrthographicCamera camera;
private Game game;
private World world;
private Random r = new Random();
public GameScreen(Game game){
camera = new OrthographicCamera();
camera.setToOrtho(false, 640, 480);
this.game = game;
world = new World();
world.setManager(new GroupManager());
spriteRenderSystem = world.setSystem(new SpriteRenderSystem(camera), true);
world.setSystem(new VelocitySystem());
world.setSystem(new AccelerationSystem());
world.setSystem(new CollisionSystem());
world.setSystem(new ExpirationSystem());
world.initialize();
for(int i = 0; i < 40; i += 4){
EntityFactory.createBlock(world, i*16, 0, "tiles/water").addToWorld();
EntityFactory.createBlock(world, (i+1) * 16, 0, "tiles/grass").addToWorld();
EntityFactory.createBlock(world, (i+2) * 16, 0, "tiles/mud").addToWorld();
EntityFactory.createBlock(world, (i+3) * 16, 0, "tiles/sand").addToWorld();
}
for(Entity e : EntityFactory.createExplosion(world, 320, 240)){
e.addToWorld();
}
}
@Override
public void render(float delta) {
// NEED HELP HERE
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
camera.update();
world.setDelta(delta);
world.process();
spriteRenderSystem.process();
}
(...)
}
注意:我正在使用LibGDX + Artemis演示SpriteRenderSystem来渲染实体。
