SpriteKit自定义节点边界

Question

I need to make a custom node boundary around this shape: http://imgur.com/TITlguy

When I use the traditional rectangle shape, it's not accurate to when the main player collides with the rounded edges.

Here is my code so far:

rightWall.physicsBody = SKPhysicsBody(rectangleOfSize: rightWall.size)
    rightWall.physicsBody?.categoryBitMask = PhysicsCatagory.platform
    rightWall.physicsBody?.collisionBitMask = PhysicsCatagory.player
    rightWall.physicsBody?.contactTestBitMask = PhysicsCatagory.player
    rightWall.physicsBody?.dynamic = false
    rightWall.physicsBody?.affectedByGravity = false

Answer 1

您应该使用带有纹理的init方法来生成物理物体。

init(texture texture: SKTexture, size size: CGSize)
