swift - 具有纹理的物理 body 会减慢 fps

Question

我有一个游戏，屏幕上同时有大约 8 个 SKPhysicsBodies，其中两个只是简单的正方形，并且是用纹理创建的。纹理并没有太复杂，这是一张图片:https://imgur.com/a/qJXL7 (黑色是透明的)。问题是，每次我生成一个使用纹理创建的PhysicsBody 时，游戏都会卡住几毫秒，从而破坏整个游戏，我怎样才能提高游戏的性能？这是我创建物理主体的方法:

createObstacle1() {
let obstTexture1 = SKTexture(imageNamed: "obst1")
let obst1 = SKSpriteNode()
    obst1.size = CGSize(width: 30, height: 30)
    obst1.color = player.color
    obst1.zPosition = 3
    obst1.physicsBody = SKPhysicsBody(texture: obstTexture1, size: obst1.size)
    obst1.physicsBody?.affectedByGravity = false
    obst1.physicsBody?.allowsRotation = false
    obst1.physicsBody?.isDynamic = false
    obst1.physicsBody?.restitution = 0
    obst1.physicsBody?.linearDamping = 0
    obst1.physicsBody?.angularDamping = 0
    obst1.physicsBody?.friction = 0
    obst1.physicsBody?.categoryBitMask = 3
    obst1.physicsBody?.collisionBitMask = 1
    obst1.physicsBody?.contactTestBitMask = 1
    obst1.name = "obst1"

    self.addChild(obst1)
}

您何时何地制造了障碍？我想正如 Knight0fdragon 所说，您必须尝试创建更新事件。愚蠢的问题。您在真实设备还是模拟器上进行测试？
