swift ゲームHPを視覚化させるのコードを簡略化したい。

Question

前提・実現したいこと

ゲームを作成している時に
体力ゲージを視覚的に見せるコードを記載しています。
全てのコードが制限により表示させられていませんが現在HP４０まで作成しています。
さらに
life41.fillColor = .yellow
life41.zPosition = など
とHP４０ごとに色を変えていき同位置に
６列のHP240まで表示したいと思っています。
HPの記載の他、そのHPゲージを削除していく過程も
冗長的になってしまっていますので今のうちに見直したいのですが良い方法が思いつきません。
アドバイスいただけると助かります。

Answer 1

少し雑ですが、こんな感じでどうでしょうか？

import SpriteKit

class GameScene: SKScene {

override func didMove(to view: SKView) {
体力ゲージ()
}
    
func damage(hit: Int){
for i in 1...hit {
    let Node = childNode(withName: "(i)")
    Node?.isHidden = true
  //  Node?.removeFromParent()
    }
}
    
func 体力ゲージ(){
for i in 1...40 {
let life = SKShapeNode(rectOf: CGSize(width: size.width/60, height: size.height/8))
let posx = size.width/60*CGFloat(10+i)
    switch i {
    case 1...10:
        life.fillColor = .orange
    case 11...20:
        life.fillColor = .white
    case 21...30:
        life.fillColor = .blue
    case 31...40:
        life.fillColor = .red
    default:
        return
    }
    life.name = "(41-i)"
    life.position = CGPoint(x: posx, y: size.height*0.9)
    addChild(life)
        }
    }


override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    let rondom = Int.random(in: 1...40)
    print(rondom)
    self.damage(hit: rondom)
    }
}

早々の回答ありがとうございます。
全体に対してアドバイスいただき感謝しかありません。
私のレベルでは理解が追い付かずどのように動作しているか理解できてない部分もありますが、
これから理解していこうと思います。
HP240まで１００行以内で実現できました。
