iOS开发实战-基于SpriteKit的FlappyBird小游戏

写在前面

最近一直在忙自己的维P恩的事情
公司项目也是一团乱
于是...随手找了个游戏项目改了改就上线了,就当充数了.

SpriteKit简介

SpriteKit是iOS 7之后苹果推出的2D游戏框架。它支持2D游戏中各种功能，如物理引擎，地图编辑，粒子，视频，声音精灵化，光照等。

SpriteKit中常用的类

• SKSpriteNode 用于绘制精灵纹理
• SKVideoNode 用于播放视频
• SKLabelNode 用于渲染文本
• SKShapeNode 用于渲染基于Core Graphics路径的形状
• SKEmitterNode 用于创建和渲染粒子系统
• SKView 对象执行动画和渲染
• SKScene 游戏内容组织成的场景
• SKAction 节点动画

效果

这是一个类似于FlappyBird的小游戏
集成GameCenter

分析

结构很简单
设计思路就是障碍物不断的移动.当把角色卡死时游戏结束

代码

1.预加载游戏结束时的弹出广告
2.加载背景
3.设置physicsBody
4.设置障碍物移动Action
5.设置开始面板角色及初始Action
6.加载所有内容节点

• 初始化

- (void)initalize
{[super initalize];SKSpriteNode* background=[SKSpriteNode spriteNodeWithImageNamed:@"sky.png"];background.size = self.view.frame.size;background.position=CGPointMake(background.size.width/2, background.size.height/2);[self addChild:background];self.physicsBody = [SKPhysicsBody bodyWithEdgeLoopFromRect:self.frame];self.physicsBody.categoryBitMask = edgeCategory;self.physicsWorld.contactDelegate = self;self.moveWallAction = [SKAction sequence:@[[SKAction moveToX:-WALL_WIDTH duration:TIMEINTERVAL_MOVEWALL],[SKAction removeFromParent]]];SKAction *upHeadAction = [SKAction rotateToAngle:M_PI / 6 duration:0.2f];upHeadAction.timingMode = SKActionTimingEaseOut;SKAction *downHeadAction = [SKAction rotateToAngle:-M_PI / 2 duration:0.8f];downHeadAction.timingMode = SKActionTimingEaseOut;self.moveHeadAction = [SKAction sequence:@[upHeadAction, downHeadAction,]];[self addGroundNode];[self addCeiling];[self addHeroNode];[self addResultLabelNode];[self addInstruction];[self runAction:[SKAction repeatActionForever:[SKAction sequence:@[[SKAction performSelector:@selector(addFish) onTarget:self],[SKAction waitForDuration:0.3f],]]] withKey:ACTIONKEY_ADDFISH];_interstitialObj = [[GDTMobInterstitial alloc]initWithAppkey:@"1106301022"placementId:@"2080622474511184"];_interstitialObj.delegate = self;//设置委托 _interstitialObj.isGpsOn = NO; //【可选】设置GPS开关//预加载广告[_interstitialObj loadAd];}

• 加载角色,设置飞行动作,触摸事件

- (void)addHeroNode
{self.hero=[SKSpriteNode spriteNodeWithImageNamed:@"player"];SKTexture* texture=[SKTexture textureWithImageNamed:@"player"];_hero.physicsBody=[SKPhysicsBody bodyWithTexture:texture size:_hero.size];_hero.anchorPoint = CGPointMake(0.5, 0.5);_hero.position = CGPointMake(self.frame.size.width / 2, CGRectGetMidY(self.frame));_hero.name = NODENAME_HERO;_hero.physicsBody.categoryBitMask = heroCategory;_hero.physicsBody.collisionBitMask = wallCategory | groundCategory|edgeCategory;_hero.physicsBody.contactTestBitMask = holeCategory | wallCategory | groundCategory|fishCategory;_hero.physicsBody.dynamic = YES;_hero.physicsBody.affectedByGravity = NO;_hero.physicsBody.allowsRotation = NO;_hero.physicsBody.restitution = 0.4;_hero.physicsBody.usesPreciseCollisionDetection = NO;[self addChild:_hero];
//    SKTexture* texture1=[SKTexture textureWithImageNamed:@"player"];
//    SKTexture* texture2=[SKTexture textureWithImageNamed:@"player3"];
//
//    SKAction *animate = [SKAction animateWithTextures:@[texture1,texture2] timePerFrame:0.1];
//    [_hero runAction:[SKAction repeatActionForever:animate]];[_hero runAction:[SKAction repeatActionForever:[self getFlyAction]]withKey:ACTIONKEY_FLY];
}- (SKAction *)getFlyAction
{SKAction *flyUp = [SKAction moveToY:_hero.position.y + 10 duration:0.3f];flyUp.timingMode = SKActionTimingEaseOut;SKAction *flyDown = [SKAction moveToY:_hero.position.y - 10 duration:0.3f];flyDown.timingMode = SKActionTimingEaseOut;SKAction *fly = [SKAction sequence:@[flyUp, flyDown]];return fly;
}- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{if (_isGameOver) {return;}if (!_isGameStart) {[self startGame];}_hero.physicsBody.velocity = CGVectorMake(100, 500);[_hero runAction:_moveHeadAction withKey:ACTIONKEY_MOVEHEAD];
}

• 加载开始说明和结束说明

- (void)addResultLabelNode
{self.labelNode = [SKLabelNode labelNodeWithFontNamed:@"PingFangSC-Regular"];_labelNode.fontSize = 30.0f;_labelNode.horizontalAlignmentMode = SKLabelHorizontalAlignmentModeLeft;_labelNode.verticalAlignmentMode = SKLabelVerticalAlignmentModeTop;_labelNode.position = CGPointMake(10, self.frame.size.height - 20);_labelNode.fontColor = COLOR_LABEL;_labelNode.zPosition=100;[self addChild:_labelNode];
}
- (void)addInstruction{self.hitSakuraToScore = [SKLabelNode labelNodeWithFontNamed:@"AmericanTypewriter"];_hitSakuraToScore.fontSize = 20.0f;_hitSakuraToScore.position = CGPointMake(self.frame.size.width / 2, CGRectGetMidY(self.frame)-60);_hitSakuraToScore.fontColor = COLOR_LABEL;_hitSakuraToScore.zPosition=100;_hitSakuraToScore.text=@"Hit fish to Score";
//    _hitSakuraToScore.text=NSLocalizedString(@"Hit Sakura to Score", nil);[self addChild:_hitSakuraToScore];self.tapToStart = [SKLabelNode labelNodeWithFontNamed:@"PingFangSC-Regular"];_tapToStart.fontSize = 20.0f;_tapToStart.position = CGPointMake(self.frame.size.width / 2, CGRectGetMidY(self.frame)-100);_tapToStart.fontColor = COLOR_LABEL;_tapToStart.zPosition=100;_tapToStart.text=@"Tap to Jump";[self addChild:_tapToStart];
}

• 加载障碍物

- (void)addWall
{CGFloat spaceHeigh = self.frame.size.height - GROUND_HEIGHT;float random= arc4random() % 4;CGFloat holeLength = HERO_SIZE.height * (2.0+random*0.1);int holePosition = arc4random() % (int)((spaceHeigh - holeLength) / HERO_SIZE.height);CGFloat x = self.frame.size.width;CGFloat upHeight = holePosition * HERO_SIZE.height;if (upHeight > 0) {SKSpriteNode *upWall = [SKSpriteNode spriteNodeWithColor:COLOR_WALL size:CGSizeMake(WALL_WIDTH, upHeight)];upWall.anchorPoint = CGPointMake(0, 0);upWall.position = CGPointMake(x, self.frame.size.height - upHeight);upWall.name = NODENAME_WALL;upWall.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:upWall.size center:CGPointMake(upWall.size.width / 2.0f, upWall.size.height / 2.0f)];upWall.physicsBody.categoryBitMask = wallCategory;upWall.physicsBody.dynamic = NO;upWall.physicsBody.friction = 0;[upWall runAction:_moveWallAction withKey:ACTIONKEY_MOVEWALL];[self addChild:upWall];}CGFloat downHeight = spaceHeigh - upHeight - holeLength;if (downHeight > 0) {SKSpriteNode *downWall = [SKSpriteNode spriteNodeWithColor:COLOR_WALL size:CGSizeMake(WALL_WIDTH, downHeight)];downWall.anchorPoint = CGPointMake(0, 0);downWall.position = CGPointMake(x, GROUND_HEIGHT);downWall.name = NODENAME_WALL;downWall.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:downWall.size center:CGPointMake(downWall.size.width / 2.0f, downWall.size.height / 2.0f)];downWall.physicsBody.categoryBitMask = wallCategory;downWall.physicsBody.dynamic = NO;downWall.physicsBody.friction = 0;[downWall runAction:_moveWallAction withKey:ACTIONKEY_MOVEWALL];[self addChild:downWall];}SKSpriteNode *hole = [SKSpriteNode spriteNodeWithColor:[UIColor clearColor] size:CGSizeMake(WALL_WIDTH, holeLength)];hole.anchorPoint = CGPointMake(0, 0);hole.position = CGPointMake(x, self.frame.size.height - upHeight - holeLength);hole.name = NODENAME_HOLE;hole.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:hole.size center:CGPointMake(hole.size.width / 2.0f, hole.size.height / 2.0f)];hole.physicsBody.categoryBitMask = holeCategory;hole.physicsBody.dynamic = NO;[hole runAction:_moveWallAction withKey:ACTIONKEY_MOVEWALL];[self addChild:hole];
}

• 游戏开始时 不断增加障碍物

- (void)startGame
{self.isGameStart = YES;_hero.physicsBody.affectedByGravity = YES;[_hero removeActionForKey:ACTIONKEY_FLY];[_tapToStart removeFromParent];[_hitSakuraToScore removeFromParent];[self addResultLabelNode];SKAction *addWall = [SKAction sequence:@[[SKAction performSelector:@selector(addWall) onTarget:self],[SKAction waitForDuration:TIMEINTERVAL_ADDWALL],]];[self runAction:[SKAction repeatActionForever:addWall] withKey:ACTIONKEY_ADDWALL];
}

• 实时更新内容

- (void)update:(NSTimeInterval)currentTime
{if(self.hero&&!_isGameOver){if ( self.hero.position.x<10) {[self gameOver];}else if(self.hero.position.x>self.frame.size.width){self.hero.position =CGPointMake(self.hero.position.x-20, self.hero.position.y);}}__block int wallCount = 0;[self enumerateChildNodesWithName:NODENAME_WALL usingBlock:^(SKNode *node, BOOL *stop) {if (wallCount >= 2) {*stop = YES;return;}if (node.position.x <= -WALL_WIDTH) {wallCount++;[node removeFromParent];}}];[self enumerateChildNodesWithName:NODENAME_HOLE usingBlock:^(SKNode *node, BOOL *stop) {if (node.position.x <= -WALL_WIDTH) {[node removeFromParent];*stop = YES;}}];[self enumerateChildNodesWithName:NODENAME_FISH usingBlock:^(SKNode *node, BOOL *stop) {if (node.position.x <= -node.frame.size.width) {[node removeFromParent];}}];
}

• 设置物体碰撞效果

- (void)didBeginContact:(SKPhysicsContact *)contact
{if (_isGameOver) {return;}SKPhysicsBody *firstBody, *secondBody;if (contact.bodyA.categoryBitMask < contact.bodyB.categoryBitMask) {firstBody = contact.bodyA;secondBody = contact.bodyB;} else {firstBody = contact.bodyB;secondBody = contact.bodyA;}if ((firstBody.categoryBitMask & heroCategory) && (secondBody.categoryBitMask & fishCategory)) {if(secondBody.node.parent&&self.isGameStart){int currentPoint = [_labelNode.text intValue];_labelNode.text = [NSString stringWithFormat:@"%d", currentPoint + 1];[self playSoundWithName:@"sfx_wing.caf"];NSString *burstPath =[[NSBundle mainBundle]pathForResource:@"MyParticle" ofType:@"sks"];SKEmitterNode *burstNode =[NSKeyedUnarchiver unarchiveObjectWithFile:burstPath];burstNode.position = secondBody.node.position;[secondBody.node removeFromParent];[self addChild:burstNode];dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{[burstNode runAction:[SKAction removeFromParent]];});}}
}

{[restartView dismiss];[self restart];}
- (void)restartView:(RestartLabel *)restartView didPressLeaderboardButton:(SKSpriteNode *)restartButton{[self showLeaderboard];
}

• 游戏结束可以调期GameCenter排行榜

-(void)showLeaderboard{GKGameCenterViewController *gcViewController = [[GKGameCenterViewController alloc] init];gcViewController.gameCenterDelegate = self;gcViewController.viewState = GKGameCenterViewControllerStateLeaderboards;gcViewController.leaderboardIdentifier = @"MyFirstLeaderboard";[self.view.window.rootViewController presentViewController:gcViewController animated:YES completion:nil];}
-(void)gameCenterViewControllerDidFinish:(GKGameCenterViewController *)gameCenterViewController
{[gameCenterViewController dismissViewControllerAnimated:YES completion:nil];
}

关于游戏上架Tips

蛋疼广电粽菊要求国内游戏必须备案...
我们只是想上个小游戏而已~难道还要再等个大半个月去备案么?
Apple也妥协了 在备注那里要求中国区上架游戏必须填写备案号

But!!!上有政策,下有对策嘛~

• 填写App分类时直接选择娱乐类型上架,就不会要求填写备案号了~
• 销售范围,不选择中国地区,这样也不会要求填写备案号,等过审了,再将销售范围改回所有地区,基本上是实时生效~

以上两种方式屡试不爽哈~对于我们个人小开发来说也算是个小福利了.

Demo地址

Github地址,欢迎Star (由于集成了广告,广点通的静态库需要单独下载下完直接扔到项目里就行)
已上架Appstore 猫爷快吃 喜欢就支持下吧~
欢迎光顾自己的小站,内容都是同步更新的~
大家低调支持下自己的 牛牛数据 Half-price~~

还没结束
