如何让相机跟随Sprite Kit中的SKNode？ [英] How to make camera follow SKNode in Sprite Kit?

问题描述

我希望背景固定不同的物体（精灵和其他物体）。

I want to have background stationary with different objects (sprites and other objects).

玩家将由将在世界各地移动的中心节点表示。我希望将相机固定到中央节点，例如世界应该移动，相机应该保持静止。

Player will be represented by center node that will move around the world. I want to have my camera pinned to central node, e.g. the world should move and the camera should stay stationary.

我如何实现这一目标？

推荐答案

这样的事情应该会有所帮助。我从didSimulatePhysics调用以下内容。

Something like this should help. I call the following from my didSimulatePhysics.

-(void)centerOnNode:(SKNode*)node {
    CGPoint cameraPositionInScene = [node.scene convertPoint:node.position fromNode:node.parent];
    cameraPositionInScene.x = 0;
    node.parent.position = CGPointMake(node.parent.position.x - cameraPositionInScene.x, node.parent.position.y - cameraPositionInScene.y);
}
