我正在用Cocos2d爲iPhone構建遊戲,現在我正試圖讓Touch輸入工作。我已經在多層場景中的獨立控制層上啓用了觸摸響應,並且它工作正常 - 除非觸摸方法在觸摸位於單獨圖層上的精靈頂部時觸發觸摸方法(單獨的圖層爲實際上只是一個節點)。除了這個精靈之外,我沒有其他的屏幕內容。Cocos2d輸入圖層僅接收精靈頂部的觸摸

這裏是我的控制層實現:

#import "ControlLayer2.h" 

extern int CONTROL_LAYER_TAG; 
@implementation ControlLayer2 
+(void)ControlLayer2WithParentNode:(CCNode *)parentNode{ 
    ControlLayer2 *control = [[self alloc] init]; 
    [parentNode addChild:control z:0 tag:CONTROL_LAYER_TAG]; 
} 

-(id)init{ 
    if (self=[super init]){ 

     [[[CCDirector sharedDirector]touchDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES]; 
    } 
    return self; 
} 

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{ 
    CCLOG(@"touchbegan"); 
    return YES; 
} 

@end 

,這裏是與內部具有精靈的子節點層:

extern int PLAYER_LAYER_TAG; 

int PLAYER_TAG = 1; 

@implementation PlayerLayer 
//reduces initializing and adding to the gamescene to one line for ease of use 
+(void)PlayerLayerWithParentNode:(CCNode *)parentNode{ 
    PlayerLayer *layer = [[PlayerLayer alloc] init]; 
    [parentNode addChild:layer z:1 tag:PLAYER_LAYER_TAG]; 
} 

-(id)init{ 
    if(self = [super init]){ 
     //add the player to the layer, know what I'm sayer(ing)? 
     [Player playerWithParentNode:self]; 
    } 
    return self; 
} 

@end 

最後,包含他們兩個場景:

int PLAYER_LAYER_TAG = 1; 
int CONTROL_LAYER_TAG = 2; 
@implementation GameScene 

+(id)scene{ 
    CCScene *scene = [CCScene node]; 
    CCLayer *layer = [GameScene node]; 
    [scene addChild:layer z:0 tag:0]; 
    return scene; 
} 

-(id)init{ 
    if(self = [super init]){ 
     //[[[CCDirector sharedDirector]touchDispatcher] addTargetedDelegate:[self getChildByTag:0] priority:0 swallowsTouches:YES]; 
     //add the player layer to the game scene (this contains the player sprite) 
     [ControlLayer2 ControlLayer2WithParentNode:self]; 
     [PlayerLayer PlayerLayerWithParentNode:self]; 

    } 
    return self; 
} 

@end 

我該如何使控制層響應所有觸摸輸入?

在init方法中添加此代碼。

self.touchEnabled = YES; 

,並使用此ccTouchesBegan

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *myTouch = [touches anyObject]; 
    CGPoint location = [myTouch locationInView:[myTouch view]]; 
    location = [[CCDirector sharedDirector] convertToGL:location]; 

    //handle touch 
} 

在你的代碼刪除此行:

[[[CCDirector sharedDirector]touchDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];

我想這一點,達到同樣的效果。 – Swanijam 2013-03-16 16:59:06

ControlLayer2的父級是GameScene。在GameScene中未啓用觸摸。因此,在GameScene中放置self.touchEnabled = YES並將ccTouchesBegan放在相同的位置... – Guru 2013-03-16 17:00:39

將所有觸摸控件放入GameScene中?我想我可以,但是我想在一個單獨的課程中處理所有的問題,以確保代碼和組織的清晰。或者你的意思是把self.touchEnabled放在gamescene中,但是ControlLayer2類中的觸摸控件? – Swanijam 2013-03-16 17:06:11
