缩放 SCNNode 时更新 SCNPhysicsBody

本文介绍了缩放 SCNNode 时更新 SCNPhysicsBody的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我知道当节点缩放时 SCNPhysicsBody 不会缩放，但我还没有找到解决这个问题的好方法.我想缩放节点，然后在缩放节点后将 SCNPhysicsBody 更新为节点.

I know that SCNPhysicsBody dont scale when the node scale, but I haven't found a great solution to fix this. I want to scale the node and then update the SCNPhysicsBody to node after scaling it.

let box = SCNBox(width: 0.2, height: 0.3, length: 0.4, chamferRadius: 0.1) box.firstMaterial?.diffuse.contents = UIColor.blue var boxNode = SCNNode(geometry: box) boxNode.scale = SCNVector3(0.5, 0.5, 0.5) boxNode.position.x += 0.5 boxNode.physicsBody = SCNPhysicsBody(type: SCNPhysicsBodyType.static, shape: SCNPhysicsShape(geometry: box, options: nil)) sceneView.scene.rootNode.addChildNode(boxNode)

有没有人想出一个很好的解决方案来解决这个问题?

Has anyone come up with a great solution to this problem?

推荐答案

试试这个

let nodeScale = SCNVector3(0.5,0.5,0.5) boxNode.physicsBody = SCNPhysicsBody(type: SCNPhysicsBodyType.static, shape: SCNPhysicsShape(geometry: box, options: [SCNPhysicsShape.Option.scale: nodeScale]))
