Swift 3: класс работает неправильно
Итак, у меня есть класс с именем FlashyPaddleEffect, Я также упоминаю это в другом классе, GameScene, но он не применяет никакого эффекта, который должен. Весло должно мигать синим и белым цветами, но оно просто остается белым. Весло также должно потерять свое физическое тело, когда оно синее.
Если вам нужна какая-либо другая информация, не стесняйтесь спрашивать.
ПРИМЕЧАНИЕ. Могут быть проблемы с кодом, который я дал (из-за отступов довольно сложно сделать код с отступом 4 пробела в каждой строке, извините).

switch node.color {
case SKColor.blue: node.color = SKColor.white
case SKColor.white: node.color = SKColor.blue
default: _ = 1 + 2
}
}
@objc func update() //I used the objc prefix to silence the warning the selectors of the timers produced. {
let previousPhysicsBody = node.physicsBody
if node.color == SKColor.blue {
node.physicsBody = nil
}
node.physicsBody = previousPhysicsBody
}

Большое спасибо за ответы. PS Это мой первый вопрос, поэтому не судите меня строго.

1) не использовать NSTimer использование SKAction, Я вижу, как ты это делаешь, ты ставишь таймер за таймером, это плохо.
2) У вас нет глобальной переменной temp (в нашем случае это node), это затрудняет чтение кода
3) Не удаляйте свое физическое тело, просто удалите категорию.
func make(applyEffectTo: SKSpriteNode, ball: SKSpriteNode) {
ballNode = ball
let blue = SKAction.colorize(with SKColor.blue, colorBlendFactor: 1.0, duration sec: 0)
let white = SKAction.colorize(with SKColor.white, colorBlendFactor: 1.0, duration sec: 0)
let wait = SKAction.wait(for:0.6)
let turnOnPhysics = SKAction.run({applyEffectTo.physicsBody?.categoryBitmask = #######})
let turnOffPhysics = SKAction.run({applyEffectTo.physicsBody?.categoryBitmask = 0})
let seq = [blue, turnOffPhysics,wait,white,turnOnPhysics,wait]
let repeat = SKAction.repeatForever(seq)
applyEffectTo.run(repeat, withKey:"flashing")
}
Примечание: я понятия не имею, что вы categoryBitmask нужно заполнить
