SpriteKit PhysicsBody非矩形碰撞 [英] SpriteKit PhysicsBody non-rectangular collision

问题描述

    pipeUp.physicsBody = SKPhysicsBody(rectangleOfSize: pipeUp.size)

在此编码中，我将rectangleOfSize用于碰撞物理体，但是如果我想仅以像素的形式使用图像的形状，我应该用什么代替rectangleOfSize?

in this coding I used the rectangleOfSize for collision physics body, but if I want to use by pixel just the shape of the image, what I should use instead of rectangleOfSize?

推荐答案

您应该制作一个CGPath来作为对象的形状，并使用SKPhysicsBody的init(polygonFromPath path: CGPath)作为

You should make a CGPath that is the shape of your object, and use SKPhysicsBody's init(polygonFromPath path: CGPath) as described here
