IOS飞机大战OC版
前一阵子看到了很多版本的打飞机游戏，有Java版的C++版本的还有C语言版的。。。
这几天闲着的时候写了一个OC版的，也正好是因为答应朋友写这个游戏来把飞机都换成他照片- -。
没有用Cocos2d框架，用的QuartzCore中的CADisplayLink来完成。
先看下完成后的效果
简单的架构思路设计如下：
图片资源与音乐资源都以单例方式实现模型，在需要的地方调用。
核心部分是对每秒60帧刷新方法中的处理。
self.gameTimer = [CADisplayLink displayLinkWithTarget:self selector:@selector(steps)];
[self.gameTimer addToRunLoop:[NSRunLoop mainRunLoop] forMode:NSDefaultRunLoopMode];
- (void)steps
{
_steps++;
if (_steps % 60 == 0)
{
[self updateGameClock];
}
//背景处理
[self.model moveBackground];
[self.bgView setBackgroundFrame1:self.model.bgFrame1 andFrame2:self.model.bgFrame2];
//英雄视图位置刷新
self.heroView.center = self.model.hero.position;
//英雄飞机射击
if (_steps % 10 == 0)
{
[self.model.hero fire];
}
//射击子弹处理
[self checkBullets];
//初始化敌机
[self initialEnemies];
//敌机移动
[self updateEnemies];
//碰撞检测
[self collisionDetector];
}
_step是静态长整型，记录刷新次数。
背景处理代码
- (void)moveBackground
{
self.bgFrame1 = CGRectOffset(self.bgFrame1, 0, RMoveOffset);
self.bgFrame2 = CGRectOffset(self.bgFrame2, 0, RMoveOffset);
CGRect topFrame = CGRectOffset(self.gameArea, 0, -self.gameArea.size.height);
if (self.bgFrame1.origin.y >= self.gameArea.size.height)
{
self.bgFrame1 = topFrame;
}
else if (self.bgFrame2.origin.y >= self.gameArea.size.height)
{
self.bgFrame2 = topFrame;
}
}
- (void)collisionDetector
{
/******子弹碰撞敌方飞机******/
NSMutableSet *removeBulletSet = [NSMutableSet set];
for (BulletView *bulletView in self.bulletViewSet)
{
Bullet *bullet = bulletView.bullet;
for (EnemyView *enemyView in self.enemyViewSet)
{
Enemy *enemy = enemyView.enemy;
if (CGRectIntersectsRect(bulletView.frame, enemyView.frame) && !enemy.toBlowup)
{
enemy.hp -= bullet.damage;
if (enemy.hp <= 0)
{
enemy.toBlowup = YES;
}
else
{
if (enemy.type == REnemyTypeBig)
{
[enemyView stopAnimating];
}
enemyView.image = enemyView.hitImage;
}
[removeBulletSet addObject:bulletView];
}
}
}
for (BulletView *bulletView in removeBulletSet)
{
[bulletView removeFromSuperview];
[self.bulletViewSet removeObject:bulletView];
}
/******爆炸处理******/
if (_steps % 4 == 0)
{
NSMutableSet *toRemovedSet = [NSMutableSet set];
for (EnemyView *enemyView in self.enemyViewSet)
{
Enemy *enemy = enemyView.enemy;
if (enemy.toBlowup)
{
enemy.speed = 0;
enemyView.image = enemyView.blowupImages[enemy.blowupFrames++];
}
if (enemy.blowupFrames == enemyView.blowupImages.count)
{
[toRemovedSet addObject:enemyView];
}
}
for (EnemyView *enemyView in toRemovedSet)
{
self.totalScore += enemyView.enemy.prize;
[self updateScoreLabel];
[self.enemyViewSet removeObject:enemyView];
[enemyView removeFromSuperview];
}
[toRemovedSet removeAllObjects];
}
/******敌机碰撞英雄飞机******/
for (EnemyView *enemyView in self.enemyViewSet)
{
if (CGRectIntersectsRect(enemyView.frame, self.model.hero.collisionRect))
{
[self.heroView stopAnimating];
NSArray *images = [ImageResources sharedImages].heroBlowupImages;
self.heroView.image = images[3];
self.heroView.animationImages = images;
self.heroView.animationDuration = 1.0f;
self.heroView.animationRepeatCount = 1;
[self.heroView startAnimating];
[self pauseGameTimer];
MyLog(@"英雄死亡");
[[SoundsTool shareSoundsTool] playSoundWithType:RSoundTypeHeroOver];
[self endGame];
}
}
}
上面是碰撞检测部分。分别对两种情况进行了处理，并对爆炸动画进行了逐帧显示。
在设置toBlowup属性中播放爆炸音效。
- (void)setToBlowup:(BOOL)toBlowup
{
if (toBlowup == NO)
{
_toBlowup = NO;
}
else
{
_toBlowup = YES;
RSoundType soundType;
switch (self.type)
{
case REnemyTypeSmall:
soundType = RSoundTypeSmallBlowup;
break;
case REnemyTypeMiddle:
soundType = RSoundTypeMiddleBlowup;
break;
case REnemyTypeBig:
soundType = RSoundTypeBigBlowup;
break;
}
[[SoundsTool shareSoundsTool] playSoundWithType:soundType];
}
}
播放音效代码，所有音效在单例初始化的时候加载到了一个字典中。方便读取。
- (void)playSoundWithType:(RSoundType)soundType
{
NSString *soundName = nil;
switch (soundType)
{
case RSoundTypeBullet:
soundName = @"bullet";
break;
case RSoundTypeSmallBlowup:
soundName = @"enemy1_down";
break;
case RSoundTypeMiddleBlowup:
soundName = @"enemy3_down";
break;
case RSoundTypeBigFly:
soundName = @"enemy2_out";
break;
case RSoundTypeBigBlowup:
soundName = @"enemy2_down";
break;
case RSoundTypeHeroOver:
soundName = @"game_over";
break;
}
[self playSoundWithSoundName:soundName];
}
- (void)playSoundWithSoundName:(NSString *)soundName
{
SystemSoundID soundId = [self.soundDict[soundName] unsignedLongValue];
AudioServicesPlaySystemSound(soundId);
}
初始化敌机方法
- (void)initialEnemies
{
NSInteger level = self.model.gameLevel;
NSInteger flag = RMaxLevel/level;
NSInteger timeS = arc4random_uniform(10*flag)+10/level+flag*1;
NSInteger timeM = arc4random_uniform(50*flag)+200/level+flag*3;
NSInteger timeB = arc4random_uniform(100*flag)+1000/level+flag*10;
Enemy *enemy = nil;
if (_steps % timeS == 0)
{
enemy = [self.model createEnemyWithType:REnemyTypeSmall andSize:[ImageResources sharedImages].smallFlyImage.size];
[self initEnemyViewWithEnemy:enemy];
}
else if (_steps % timeM == 0)
{
enemy = [self.model createEnemyWithType:REnemyTypeMiddle andSize:[ImageResources sharedImages].middleFlyImage.size];
[self initEnemyViewWithEnemy:enemy];
}
else if (_steps % timeB == 0)
{
enemy = [self.model createEnemyWithType:REnemyTypeBig andSize:[[ImageResources sharedImages].bigFlyImages[0] size]];
[self initEnemyViewWithEnemy:enemy];
[[SoundsTool shareSoundsTool] playSoundWithType:RSoundTypeBigFly];
}
}
敌机初始化时间这个设定看习惯随便了，由于游戏中大部分方法都进行了封装，就不全贴出来了。可以自行下载，从架构到编写时间比较短，而且出现道具的功能也没有实现，希望有改进的建议或者改进后的例子可以交流。
补充这个游戏是用Xcode5写的，另外附上用Iphone4玩时候内存和CPU的使用情况。
