ios - SceneKit: move SCNNode by setting velocity property directly like in SpriteKit?

Question

In SpriteKit, it's possible to move nodes by directly setting their velocity property.

This doesn't seem to work in SceneKit, however. Setting velocity -- both in game loop callbacks and outside of game loop functions -- seems to have no effect.

This answer from one of the Apple SceneKit engineers suggests accessing the velocity property is only possible during a game loop callback like updateAtTime.

So clearly there are limitations around the velocity property.

Is controlling the property directly not possible with SCNNodes?

正如@Confused 所指出的，文档显示可以velocity直接设置：https ://developer.apple.com/reference/scenekit/scnphysicsbody/1514757-velocity

关键是使用动态的身体类型，而不是运动的（显然不是静态的）。
