Spritekit FPS掉落问题

问题描述

我正在构建的应用程序会在创建精灵节点时降低FPS，我搜索了广泛的帖子，无法弄清楚为什么，如果有人有任何想法，我将不胜感激！

问题发生在模拟器和设备上。

下面是用于创建节点的代码。

谢谢。

@objc func createEnemy(){

        let randomDistribution = GKRandomDistribution(lowestValue: -350,highestValue: 350)
        let sprite = SKSpriteNode(imageNamed: "Virus")

        sprite.position = CGPoint(x: 700,y: randomDistribution.nextInt())
        sprite.name = "Virus"
        sprite.zPosition = 1
        sprite.size = CGSize(width: 70,height: 70)
        addChild(sprite)

        sprite.physicsBody = SKPhysicsBody(texture: sprite.texture!,size: sprite.size)
        sprite.physicsBody?.velocity = CGVector(dx: -500,dy: 0)
        sprite.physicsBody?.linearDamping = 0

        sprite.physicsBody?.contactTestBitMask = 1
        sprite.physicsBody?.categoryBitMask = 0
        sprite.physicsBody?.affectedByGravity = false

        createBonus()
    }

    func createBonus(){

        let randomDistribution = GKRandomDistribution(lowestValue: -350,highestValue: 350)
        let sprite = SKSpriteNode(imageNamed: "Vaccine")

        sprite.position = CGPoint(x: 700,y: randomDistribution.nextInt())
        sprite.name = "Vaccine"
        sprite.size = CGSize(width: 70,height: 70)
        sprite.zPosition = 1
        addChild(sprite)

        sprite.physicsBody = SKPhysicsBody(texture: sprite.texture!,dy: 0)
        sprite.physicsBody?.linearDamping = 0

        sprite.physicsBody?.contactTestBitMask = 1
        sprite.physicsBody?.categoryBitMask = 0
        sprite.physicsBody?.collisionBitMask = 0
        sprite.physicsBody?.affectedByGravity = false
    }

解决方法

您是否尝试过预加载纹理？

map_err(|_| panic!())
