[cocos2d] 游戏里面的场景过渡

1. scene: OtherScene
2. init: <OtherScene = 066B2130 | Tag = -1>
3. onEnter: <OtherScene = 066B2130 | Tag = -1>
4. // 这里运行了过渡效果
5. onExit: <FirstScene = 0668DF40 | Tag = -1>
6. onEnterTransitionDidFinish: <OtherScene = 066B2130 | Tag = -1>
7. dealloc: <FirstScene = 0668DF40 | Tag = -1>

上面的是cocos2d里面的场景过渡日志,可以发现很有趣的,A场景过渡到B场景的时候,A场景发起replaceScene请求,就init B场景,然后执行B场景的onEnter函数,程序执行到这里,就说明B场景init完成,然后对A场景执行onExit和dealloc请求,最后请求A场景的onEnterTransitionDidFinish,这样就完成了2个场景

[cocos2d] OpenGL draw base functions

-(void) draw
{
CGSize s = [[CCDirector sharedDirector] winSize];

// draw a simple line
// The default state is:
// Line Width: 1
// color: 255,255,255,255 (white, non-transparent)
// Anti-Aliased
glEnable(GL_LINE_SMOOTH);

ccDrawLine( ccp(0, 0), ccp(s.width, s.height) );

// line: color, width, aliased
// glLineWidth > 1 and GL_LINE_SMOOTH are not compatible
// GL_SMOOTH_LINE_WIDTH_RANGE = (1,1) on iPhone
glDisable(GL_LINE_SMOOTH);
glLineWidth( 5.0f );

[cocos2d] CCTransitionScene

CCTransitionScene – 所有过渡效果的基类

//淡入淡出
CCFadTransition *tran = [CCFadTransition transitionWithDuration:1
scene:[HelloWorld scene]
withColor:ccWHITE];

[[CCDirector sharedDirector] replaceScene:tran];
CCFadTransition: 淡入淡出到一个指定颜色,然后再回来
CCFadTRTransition(3):瓦片(tiles)反转过来提示场景
CCJumpZoomTransition:场景跳动着变小时,新场景则跳动着变大
MoveInLTransition(3):场景移出,同时新的场景从左(3)移入.

CCOrientedTransitionScene(6):

[cocos2d] cocos2d里面一些实用的东西

leave a comment

允许屏保

[self setScreenSaverEnabled:YES];
#pragma mark Reset Game
// The game is played only using the accelerometer. The screen may go dark while playing because the player
// won’t touch the screen. This method allows the screensaver to be disabled during gameplay.
-(void) setScreenSaverEnabled:(bool)enabled
{
UIApplication *thisApp = [UIApplication sharedApplication];
thisApp.idleTimerDisabled = !enabled;
}

启用重力感应

self.isAccelerometerEnabled = YES;

启用触摸屏

self.isTouchEnabled = NO;

[cocos2d] schedule

leave a comment

在处理Sprite的时候,需要设置Sprite的行为,需要使用到schedule,第一个参数就是selector对象,额~ 理解成C语言的函数指针就对了~

[self unschedule:@selector(spidersUpdate:)];
[self schedule:@selector(spidersUpdate:) interval:3.0f];
[self scheduleUpdate];//==[self scheduleUpdate:@selector(update:) interval:0.0f];

[cocos2d] CCArray类

leave a comment

你可以在Xcode项目中的cocos2d/Support组找到CCArray的类文件。cocos2d引擎内部使用了CCArray。它和苹果官方的NSMutableArray类似,但是运行效率更高。 CCArray类实现了NSArray和NSMutableArray的子集,并且添加一些从NSArray初始化到CCArray的新方法。CCArray通过将数组中的最后一个对象(nil)赋值给删除的位置,实现了fastRemoveObject和fastRemoveObjectAtIndex两个方法。避免了复制部份数组的内存。这让删除数组中的元素变的更快,不过这也意味着 CCArray中的对象会改变位置。如果你的程序依赖于指定的对象排列次序,你就不应该使用fastRemoveObject这类方法。在列表4-9中,你可以看到CCArray的类引用 – 它没有实现所有的NSArray和NSMutableArray方法:
列表4-9. CCArray的类引用

+ (id) arrayWithCapacity:(NSUInteger)capacity; + (i
