在SpriteKit中配置SKScene内容的正确位置在哪里? [英] Where is the right place to configure SKScene content in SpriteKit?

问题描述

可以使用init方法配置(定位精灵，添加可见节点等)SKScene的内容吗?

Is it ok to configure (position sprites, add visible nodes etc) an SKScene's content in init method?

在什么地方合适的地方:init? didMoveToView?还有其他东西吗?

Where is the right place for such things: init? didMoveToView? something else?

推荐答案

didMoveToView:. 在didMoveToView中定位和添加精灵的优点:您可以初始化许多视图，而无需占用大量内存.缺点:如果删除视图然后再次添加它，则didMoveToView:再次被调用.这意味着您必须确保在didMoveToView的开头重置场景:(仅当您打算删除并再次添加时).

didMoveToView: is called every time the scene is presented by an SKView. Pros of positioning and adding sprites in didMoveToView: You can initialise many views without them grabbing a lot of memory. Cons: If you remove a view and then add it again didMoveToView: is called again. This means that you need to be sure to reset your scene in the beginning of didMoveToView: (only if you intend to remove and add again).

init .使用init定位和添加精灵的优点:它仅被调用一次，一旦在场景中呈现，一切都将准备就绪.如果您需要预加载场景以快速切换，这可能会很方便.缺点:每个场景在初始化时(而不是在显示时)都将占用执行所有精灵添加所需的内存.

init is called when you initialise the SKScene. Pros of using init for positioning and adding sprites: It is only called once, and everything will be ready once you present it on the scene. If you need to preload scenes for quick switching this might be handy. Cons: Each scene will take up the memory it needs to perform all the adding of sprites when init'ed and not when its shown.

我个人更喜欢使用 init 方法进行所有操作.

Personally, I prefer to do everything in the init method.
