在SceneKit中为对象着色等于什么？

Question

How can I animate a change in color of an SCNNode ? In SpriteKit I would just use the colorizeWithColor SKAction , but that is not an option in SceneKit . In SpriteKit , I would typically have a collision between two nodes. When the nodes collided one of the nodes changed colors simply by running the colorizeWithColor SKAction . What's the equivalent of this in SceneKit for an SCNNode ?

You can use the multiply property of your material to achieve a similar effect. You can set the fade length with SCNTransaction 's animationDuration property.

SCNTransaction.begin()
SCNTransaction.animationDuration = yourFadeDuration
geometry?.firstMaterial?.multiply.contents = yourDesiredColor
SCNTransaction.commit()
