使用SpriteKit和SWIFT为游戏构建网格级别 [英] Build a grid level for a game with SpriteKit and SWIFT

问题描述

我正在寻找构建游戏关卡的最佳方法：

I’m searching the best way to build the levels for a game :

• 游戏将由许多关卡组成，每个关卡级别将是
  唯一。


• 您将播放一个对象（这里是星星），该对象在网格中移动
  。


• 对象只能移动到底部，不能后退。


• 一个关卡由很多情况组成，每种情况会有不同的情况
  的行为。


• 我的水平仪将具有背景，屏幕的宽度，但是
  的高度将取决于水平仪，我想屏幕的高度
  会是很多倍。


• 背景根据对象的移动而变化

• The game will be composed with many levels, each levels will be unique.
• You’ll play an object (here the star), which is in movement on a grid.
• The object can move only to the bottom, it cannot go back.
• A level is composed with many cases, each cases will have a different behavior.
• My level will have a background, width of the screen, but the height will depend on the level, I suppose many times the height of the screen.
• The background moves depending on the object movements

目前，我正在研究

阅读了很多教程，我的想法是使用SKSpriteNode创建x个正方形（菱形）。并用标识符标识正方形。

After reading many tutorials, my idea is to create x squares (diamond-shape) using SKSpriteNode. And to identify the squares with identifiers.

我不知道这在性能方面是否是一个好的解决方案？它们将在一个级别中包含许多正方形。我不知道：）

I don’t know if it’s a good solution in terms of performance? They will be a lot of squares in one level. I don’t realize :)

我们是否受一个场景中节点数的限制？

Are we limited with the numbers of node in one scene?

推荐答案

我认为没有必要。您还可以使用由 CGPath 正方形填充的单个 SKSpriteNode 背景，如果您制作了一个非常快速的游戏，想要增加难度。您可以通过与每个 CGPath 一起组织游戏的功能性部分，在这种情况下必须更改正方形时，可以使用 CGPath ，使用涉及的 CGPath 为它赋予一个名称，例如基于索引以轻松了解其名称，使用此 SKSpriteNode 可以：

I think it's not necessary. You can also use a single SKSpriteNode background populated by squares CGPath's and you can make a very fast game if you want to increase difficult levels. You can organize your "functional" part of game by working with each CGPath and when you must change a square in this case you can create a square using the CGPath that represent that square, give to it a name based for example to an index to easily understand who it is, using the CGPath involved and use this SKSpriteNode to:

• 隐藏正方形背景


• 产生类似爆炸的效果


• 更改正方形的颜色，而不是普通正方形的颜色


• 等。

• cover the square background
• make an effect like explosion
• change color of a square instead of general square colors
• etc..

PS：我已经看到您要创建一个scrollView，在swift中有一个不错的Spritekit库，名为 CustomScrollView 此处可能有用，只需使用：

P.S.: I've seen you want to create a scrollView, there is a nice Spritekit library in swift called CustomScrollView here that can be useful , it's simply to use:

scrollView = CustomScrollView(frame: CGRect(x: 0, y: 0, width: self.frame.size.width, height: self.frame.size.height), scene: self, moveableNode: moveableNode, scrollDirection: .Vertical)
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width, scrollView.frame.size.height * 3) // makes it 3 times the height
view?.addSubview(scrollView)

更新：关于您的评论，答案是肯定的：当您使用路径时，您将使用按点组织的一组元素（请看以下发布以了解操作方法。）

Update: about your comment, the answer is yes: when you work with a path you work with a group of elements organized in points (take a look at this post to understand how).

您可以使用本机：

CGPathContainsPoint(<#T##path: CGPath?##CGPath?#>, <#T##m: UnsafePointer<CGAffineTransform>##UnsafePointer<CGAffineTransform>#>, <#T##point: CGPoint##CGPoint#>, <#T##eoFill: Bool##Bool#>)

或使用以下命令：

CGPathGetPathBoundingBox(<#T##path: CGPath?##CGPath?#>)

要使用它：

CGRectIntersectsRect(<#T##rect1: CGRect##CGRect#>, <#T##rect2: CGRect##CGRect#>)
