我在黑暗的屏幕上有一个移动的黑色图像,以便更容易看到我想为图像添加白色光晕.这是我的动态图像代码:

   Ghost = SKSpriteNode(imageNamed: "Ghost1")
Ghost.size = CGSize(width: 50, height: 50)
Ghost.position = CGPoint(x: self.frame.width / 2 - Ghost.frame.width, y: self.frame.height / 2)

Ghost.physicsBody = SKPhysicsBody(circleOfRadius: Ghost.frame.height / 1.4)
Ghost.physicsBody?.categoryBitMask = PhysicsCatagory.Ghost
Ghost.physicsBody?.collisionBitMask = PhysicsCatagory.Ground | PhysicsCatagory.Wall
Ghost.physicsBody?.contactTestBitMask = PhysicsCatagory.Ground | PhysicsCatagory.Wall | PhysicsCatagory.Score
Ghost.physicsBody?.affectedByGravity = false
Ghost.physicsBody?.isDynamic = true
Ghost.zPosition = 2

self.addChild(Ghost)

我不知道如何或如何使用添加发光,如果您需要更多信息,请询问.
