swift - SpriteKit : how to find the position at which two sprites or physics bodies contact

Question

我创建了两个 Sprite 并处理了它们的接触。我想在两个物体接触的位置创建一个新的 Sprite 。我怎样才能得到一个接触的 Sprite 的位置？

Answer 1

请查看 SKPhysicsContact 类。 (See here)

To receive contact messages, read the physicsWorld property of an SKScene object you are interested in, and assign its contactDelegate property to point to an object that implements the SKPhysicsContactDelegate protocol. Then, for each physics body in your scene, set the categoryBitMask and contactTestBitMask properties to define which interactions should generate contact messages.

在生成的 SKPhysicsContact 属性上，您可以读取 contactPoint 变量。
