Ios 如何在Sprite工具包中显示包含所有子节点的父节点？

我在将所有精灵节点添加到单个父节点，然后在屏幕上显示该父节点内部的所有子节点时遇到问题

我当前的工作方法是简单地获取添加到sprite方法中的子对象，并在

-（id）initWithSize:（CGSize）size

方法中调用它

因此，它看起来和工作原理如下：

菜单中的代码。m:

- (id)initWithSize:(CGSize)size{
    if(self = [super initWithSize:size]){

        _skyColor = [SKColor colorWithRed:25.0/255.0 green:171.0/225 blue:1 alpha:1];

        [self setBackgroundColor:_skyColor];

        [self nameMovement];
        [self playButtonPushed];
        [self groundMovement];
        [self cloudMovement];
    }

    return self;
}

- (id)initWithSize:(CGSize)size{
    if(self = [super initWithSize:size]){

        _skyColor = [SKColor colorWithRed:25.0/255.0 green:171.0/225 blue:1 alpha:1];

        [self setBackgroundColor:_skyColor];

        SKNode *_moving = [SKNode node];

        [self addChild:_moving];
    }

    return self;
}

- (void)groundMovement{
    //Ground texture declaration
    groundTexture = [SKTexture textureWithImageNamed:@"Ground"];
    groundTexture.filteringMode = SKTextureFilteringNearest;

    //SKAction Declarations
    groundSpriteMovement = [SKAction moveByX:-groundTexture.size.width/2 y:0 duration:0.04 * 100];
    resetgroundSpriteMovement = [SKAction moveByX:groundTexture.size.width/2 y:0 duration:0];
    repeatForevergroundSpriteMovement = [SKAction repeatActionForever:[SKAction sequence:@[groundSpriteMovement, resetgroundSpriteMovement]]];

    //Ground Sprite declaration
    groundSprite = [SKSpriteNode spriteNodeWithTexture:groundTexture];
    groundSprite.anchorPoint = CGPointMake(0, 0);
    groundSprite.position = CGPointMake(0, 0);
    [groundSprite runAction:repeatForevergroundSpriteMovement];

    [_moving addChild:groundSprite];

}

下面的代码运行得很好，但我希望只有一个节点包含groundMovement、cloudMovement等方法所包含的所有子节点

我尝试过创建一个名为_moving的新SKNode，然后对其他保持精灵移动的方法执行此操作

下面是groundMovement方法，我尝试在其中实现我创建的父节点_moving（我唯一做的更改是在底部）。同样，当我这样做时，我通过添加

\u moving=[SKNode node]，在新的initWithSize中初始化了SKNode
声明SKNode并尝试绘制父节点的新initWithSize（SKNode*\u移动在.h文件中）：

- (id)initWithSize:(CGSize)size{
    if(self = [super initWithSize:size]){

        _skyColor = [SKColor colorWithRed:25.0/255.0 green:171.0/225 blue:1 alpha:1];

        [self setBackgroundColor:_skyColor];

        [self nameMovement];
        [self playButtonPushed];
        [self groundMovement];
        [self cloudMovement];
    }

    return self;
}

- (id)initWithSize:(CGSize)size{
    if(self = [super initWithSize:size]){

        _skyColor = [SKColor colorWithRed:25.0/255.0 green:171.0/225 blue:1 alpha:1];

        [self setBackgroundColor:_skyColor];

        SKNode *_moving = [SKNode node];

        [self addChild:_moving];
    }

    return self;
}

- (void)groundMovement{
    //Ground texture declaration
    groundTexture = [SKTexture textureWithImageNamed:@"Ground"];
    groundTexture.filteringMode = SKTextureFilteringNearest;

    //SKAction Declarations
    groundSpriteMovement = [SKAction moveByX:-groundTexture.size.width/2 y:0 duration:0.04 * 100];
    resetgroundSpriteMovement = [SKAction moveByX:groundTexture.size.width/2 y:0 duration:0];
    repeatForevergroundSpriteMovement = [SKAction repeatActionForever:[SKAction sequence:@[groundSpriteMovement, resetgroundSpriteMovement]]];

    //Ground Sprite declaration
    groundSprite = [SKSpriteNode spriteNodeWithTexture:groundTexture];
    groundSprite.anchorPoint = CGPointMake(0, 0);
    groundSprite.position = CGPointMake(0, 0);
    [groundSprite runAction:repeatForevergroundSpriteMovement];

    [_moving addChild:groundSprite];

}

地面移动方法：

- (id)initWithSize:(CGSize)size{
    if(self = [super initWithSize:size]){

        _skyColor = [SKColor colorWithRed:25.0/255.0 green:171.0/225 blue:1 alpha:1];

        [self setBackgroundColor:_skyColor];

        [self nameMovement];
        [self playButtonPushed];
        [self groundMovement];
        [self cloudMovement];
    }

    return self;
}

- (id)initWithSize:(CGSize)size{
    if(self = [super initWithSize:size]){

        _skyColor = [SKColor colorWithRed:25.0/255.0 green:171.0/225 blue:1 alpha:1];

        [self setBackgroundColor:_skyColor];

        SKNode *_moving = [SKNode node];

        [self addChild:_moving];
    }

    return self;
}

- (void)groundMovement{
    //Ground texture declaration
    groundTexture = [SKTexture textureWithImageNamed:@"Ground"];
    groundTexture.filteringMode = SKTextureFilteringNearest;

    //SKAction Declarations
    groundSpriteMovement = [SKAction moveByX:-groundTexture.size.width/2 y:0 duration:0.04 * 100];
    resetgroundSpriteMovement = [SKAction moveByX:groundTexture.size.width/2 y:0 duration:0];
    repeatForevergroundSpriteMovement = [SKAction repeatActionForever:[SKAction sequence:@[groundSpriteMovement, resetgroundSpriteMovement]]];

    //Ground Sprite declaration
    groundSprite = [SKSpriteNode spriteNodeWithTexture:groundTexture];
    groundSprite.anchorPoint = CGPointMake(0, 0);
    groundSprite.position = CGPointMake(0, 0);
    [groundSprite runAction:repeatForevergroundSpriteMovement];

    [_moving addChild:groundSprite];

}

“我宁愿只有一个节点容纳groundMovement、cloudMovement……等方法所包含的所有子节点”。有一个节点包含所有子节点，它是SKScene（self）。它目前是如何呈现的？请提供相同的描述。@akashg我的意思是，当我创建一个名为_moving的SKNode时。我将把我所有的精灵节点，如groundSprite、cloudSprite…等存储在一个移动节点中。因此，在initWithSize方法中，它只需要绘制一次，而不是在我当前的工作方法中绘制4次。为什么要这样做？保存3个绘制调用（如果这是您的意图）几乎不会对fps产生影响（如果这是您的目标）。@learncos2D代码行数越少，代码看起来越简单、越漂亮：3
