} 看着代码挺多其实就是一个update()和checkCollisions还有重要的generateLevel。接下来就是渲染WorldRenderer类中绘制各个物体/**渲染游戏中各种物体Bob,跳板松鼠弹簧城堡金币**/private void renderObjects() {batch.enableBlending();batch.begin();renderPlatforms(); //绘制跳板renderBob(); //绘制主角renderItems(); //绘制金币和弹簧renderSquirrels(); //绘制松鼠renderCastle(); //绘制城堡batch.end();} 由于代码过多这里就不一一贴出来了大家可以自行参考源码有注解的哦!既然添加了游戏中的物体那自然又得在Asset中加载资源声明//游戏中各种物体public static TextureRegion platform; //跳板public static Animation brakingPlatform; //破碎的跳板动画//主角public static Animation bobJump; //跳跃动画public static Animation bobFall; //下落动画public static TextureRegion bobHit; //碰撞图片public static TextureRegion spring; //弹簧public static TextureRegion castle; //城堡public static Animation coinAnim; //金币 动画public static Animation squirrelFly; //飞着的松鼠 动画实例化//游戏中各个物体platform new TextureRegion(items, 64, 160, 64, 16); //跳板brakingPlatform new Animation(0.2f, new TextureRegion(items, 64, 160, 64, 16), new TextureRegion(items, 64, 176, 64, 16),new TextureRegion(items, 64, 192, 64, 16), new TextureRegion(items, 64, 208, 64, 16));//破碎的跳板spring new TextureRegion(items, 128, 0, 32, 32); //弹簧castle new TextureRegion(items, 128, 64, 64, 64); //城堡coinAnim new Animation(0.2f, new TextureRegion(items, 128, 32, 32, 32), new TextureRegion(items, 160, 32, 32, 32),new TextureRegion(items, 192, 32, 32, 32), new TextureRegion(items, 160, 32, 32, 32)); //金币squirrelFly new Animation(0.2f, new TextureRegion(items, 0, 160, 32, 32), new TextureRegion(items, 32, 160, 32, 32)); //飞着的松鼠//主角bobJump new Animation(0.2f, new TextureRegion(items, 0, 128, 32, 32), new TextureRegion(items, 32, 128, 32, 32));bobFall new Animation(0.2f, new TextureRegion(items, 64, 128, 32, 32), new TextureRegion(items, 96, 128, 32, 32));bobHit new TextureRegion(items, 128, 128, 32, 32); 运行一下代码我们发现我们操作者主角向上移动会遇到弹簧会破碎的跳板飞着的松鼠金币一切都正常的运行着 仔细一看加上金币后分数值没有改变哦当然还有死亡的判断音效的加入等等。效果图在此先做一个代码版本方便初学者能够清楚的了解代码×××http://down.51cto.com/data/897211下面我们来完成分值的计算在GameScreen中/**游戏运行状态**/private void updateRunning (float deltaTime) {if (Gdx.input.justTouched()) {guiCam.unproject(touchPoint.set(Gdx.input.getX(), Gdx.input.getY(), 0));//点击暂停if (OverlapTester.pointInRectangle(pauseBounds, touchPoint.x, touchPoint.y)) {Assets.playSound(Assets.clickSound);state GAME_PAUSED;return;}}ApplicationType appType Gdx.app.getType();// should work also with Gdx.input.isPeripheralAvailable(Peripheral.Accelerometer)if (appType ApplicationType.Android || appType ApplicationType.iOS) {world.update(deltaTime, Gdx.input.getAccelerometerX());} else {float accel 0;if (Gdx.input.isKeyPressed(Keys.DPAD_LEFT)) accel 5f;if (Gdx.input.isKeyPressed(Keys.DPAD_RIGHT)) accel -5f;world.update(deltaTime, accel);}//当前分数变化if (world.score ! lastScore) {lastScore world.score;scoreString SCORE: lastScore;}//本关结束if (world.state World.WORLD_STATE_NEXT_LEVEL) {state GAME_LEVEL_END;}//游戏结束分值计算if (world.state World.WORLD_STATE_GAME_OVER) {state GAME_OVER;if (lastScore Settings.highscores[4])scoreString NEW HIGHSCORE: lastScore;elsescoreString SCORE: lastScore;//获取最后分数Settings.addScore(lastScore);//保存分数Settings.save();}} 这里我们每次碰到金币就会加上10分到游戏结束后将最终得分保存起来同时更新排行榜。Settingspackage com.zhf.mylibgdx;

} 再次运行代码加了几个金币分值发生变化了回到主界面分数排行榜也发生变化了原先默认100, 80, 50, 30, 10接下来就是声音部分:我们再次回到GameScreen中//实例化场景worldListener new WorldListener() {Overridepublic void jump () {Assets.playSound(Assets.jumpSound);}Overridepublic void highJump () {Assets.playSound(Assets.highJumpSound);}Overridepublic void hit () {Assets.playSound(Assets.hitSound);}Overridepublic void coin () {Assets.playSound(Assets.coinSound);}}; 在监听器中给对应方法播放对应的声音当然少不了在Asset中添加对声音资源的加载声明//声音部分public static Sound clickSound; //按下音效public static Music music; //背景音乐public static Sound jumpSound; //跳跃public static Sound highJumpSound; //高跳public static Sound hitSound; //碰撞public static Sound coinSound; //金币实例化//背景音乐music Gdx.audio.newMusic(Gdx.files.internal(data/music.mp3));music.setLooping(true); //循环music.setVolume(0.5f); //大小if (Settings.soundEnabled) music.play();jumpSound Gdx.audio.newSound(Gdx.files.internal(data/jump.ogg));highJumpSound Gdx.audio.newSound(Gdx.files.internal(data/highjump.ogg));hitSound Gdx.audio.newSound(Gdx.files.internal(data/hit.ogg));coinSound Gdx.audio.newSound(Gdx.files.internal(data/coin.ogg));//点击音效clickSound Gdx.audio.newSound(Gdx.files.internal(data/click.ogg));ok运行一下貌似没有什么问题对应的声音都播放出来了 到此为止libgdx中demo程序superjumper分版本的学习就结束了由于本人也是边学边总结中间肯定有许多地方讲解的不完善不妥的地方这里先想大家说声抱歉哈希望大家发现问题能及时提出来这样我也能进步么这里还是那句话在学习新东西的时候我们的不求甚解也不失为一种快速掌握的好方法 希望这一些列学习笔记能帮助到初学者完整代码下载http://down.51cto.com/data/897232 代码里详细注解哦 转载于:https://blog.51cto.com/smallwoniu/1263957
