爲什麼碰撞不起作用，cocos2d v3？

Question

我使用cocos2d v3創建了像fla鳥一樣簡單的遊戲。 接口類：

@interface GameScene : CCScene<CCPhysicsCollisionDelegate> 

// ----------------------------------------------------------------------- 

+ (GameScene *)scene; 
- (id)init; 

// ----------------------------------------------------------------------- 
@end 

在.m文件：

  _physicsWorld =[CCPhysicsNode node]; 
      _physicsWorld.gravity=ccp(0, 0); 
      _physicsWorld.collisionDelegate=self; 
      _physicsWorld.debugDraw =YES; 
      [self addChild:_physicsWorld]; 
      ......... 
      bird.physicsBody=[CCPhysicsBody bodyWithRect:(CGRect){CGPointZero,bird.contentSize} cornerRadius:0]; 
      bird.physicsBody.collisionGroup=@"birdGroup"; 
      bird.physicsBody.collisionType=@"birdCollision"; 
      [_physicsWorld addChild:bird]; 
      ........ 

    tubeBody.physicsBody.collisionGroup =@"tubeGroup"; 
    tubeBody.physicsBody.collisionType=@"tubeCollision"; 
    tubeBody.physicsBody.type=CCPhysicsBodyTypeStatic; 

    [_physicsWorld addChild:tubeBody]; 
-(BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair typeA:(CCNode *)nodeA typeB:(CCNode *)nodeB{ 
    [self endGame]; 
    NSLog(@"end game"); 
    return YES; 
} 

爲什麼方法ccPhysicsCollisionBegin從來沒有打電話？

Answer 1

變化

-(BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair typeA:(CCNode *)nodeA typeB:(CCNode *)nodeB{ 

要：

-(BOOL)ccPhysicsCollisionBegin:(CCPhysicsCollisionPair *)pair tubeCollision:(CCNode *)nodeA birdCollision:(CCNode *)nodeB{ 

你有碰撞委託的示例代碼，所以你要它適應您的nodeA上你的代碼是管和節點B的鳥。
