Sprite Kit - 隱藏SKSpriteNode

當我的玩家與它碰撞時，我怎樣才能讓我的硬幣消失？Sprite Kit - 隱藏SKSpriteNode

我不知道我是否應該使用SKNode，而不是：/。

請幫我似乎無法弄清楚

CODE：

-(void)spawnCoin { 

SKNode* coinNode = [SKNode node]; 
coinNode.position = CGPointMake(self.frame.size.width + _buildTexture1.size.width + 150 + (arc4random() % 100), 0); 
coinNode.zPosition = -10; 

CGFloat y = arc4random() % (NSInteger)(self.frame.size.height/2) + 40; 

SKAction* spin = [SKAction repeatActionForever:[SKAction animateWithTextures:@[ _coinTexture1, _coinTexture2, _coinTexture3, _coinTexture4, _coinTexture5, _coinTexture6, _coinTexture7, _coinTexture8, _coinTexture9, _coinTexture10] timePerFrame:0.05]]; 
coin = [SKSpriteNode spriteNodeWithTexture:_coinTexture10]; 
[coin runAction:spin]; 


[coin setScale:1]; 
coin.position = CGPointMake(0, y); 
coin.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:coin.size]; 
coin.physicsBody.dynamic = NO; 
coin.physicsBody.categoryBitMask = coinCategory; 
coin.physicsBody.contactTestBitMask = playerCategory; 
[coinNode addChild:coin]; 
[coinNode runAction:_moveCoinAndRemove]; 
[_coins addChild:coinNode]; 


} 

- (void)didBeginContact:(SKPhysicsContact *)contact { 
if(_moving.speed > 0) { 
    if((contact.bodyA.categoryBitMask & coinCategory) == coinCategory || (contact.bodyB.categoryBitMask & coinCategory) == coinCategory) { 

     //I have Tried [coin removeAllChildren]; 


     _score++; 
     _scoreLabelNode.text = [NSString stringWithFormat:@"%ld", (long)_score]; 
}

[硬幣removeFromParent] – LearnCocos2D

不適用於我的任何其他想法？ – nickivey

如果您要清除硬幣，它應該消失，只要'硬幣'不是零。如果它不消失，你可能會在同一地點有兩個硬幣。 – LearnCocos2D

首先得到硬幣節點。它可以是contact.bodyA.node或contact.bodyB.node。例如： -

SKNode* coinNode = contact.bodyA.node; 
[coinNode removeFromParent]; //This should work

如果你只想隱藏節點，然後

coinNode.hidden = YES;
