如何将对象/类作为函数的参数传递

Suppose I have this cat class and I make 2 instance of it. I want cat can attack each other

假设我有一个cat类，我做了两个实例。我想让猫互相攻击

class ninjaCat {
   var health : Double = 100.00
   var attack = Double()

   init(attack : Double){
      self.attack = attack
   }

   func thunderClaw(otherCat : ninjaCat){
      health = otherCat.health
      otherCat.health = health - self.attack
   }
}

var NinjaCat1 = ninjaCat(10.60)
var NinjaCat2 = ninjaCat(20.15)

NinjaCat1.thunderClaw(NinjaCat2)

Is it posible to pass class object as function parameter?

是否可以将类对象作为函数参数传递?

It is possible indeed. However you should check you code there because your using the attacking cat's current life instead of the target's to compute the remaining life:

这确实是可能的。但是，您应该检查您的代码，因为您使用攻击猫的当前生命而不是目标的生命来计算剩余生命:

func thunderClaw(otherCat : ninjaCat){
   otherCat.health = health - self.attack
}

should be

应该是

func thunderClaw(otherCat : ninjaCat){
   otherCat.health = otherCat.health - self.attack
}

or simply

或者简单地

func thunderClaw(otherCat : ninjaCat){
   otherCat.health -= self.attack
}
