macos - 如何在 Mac Cocoa App (Swift) 上显示进度条

Question

我目前正在学习 Swift，尤其是 Mac，我试图制作一种口袋妖怪对战游戏。为此，我想显示健康点的进度条，但我只能找到条纹的。我不知道我是否可以让它们根据给定值进行更改，或者我是否没有使用正确类型的 IBOutlet。

如果有人知道如何显示进度条，这就是我所需要的 :)

谢谢

(我是法国人，请原谅我可能犯的错误...)

编辑:这是我的一些代码

变量:

class AppDelegate: NSObject, NSApplicationDelegate {

@IBOutlet var window: NSWindow?

var firstPokemon:Pokemon = Pokemon(name: "Aquali", level: 50, HP: 245, power: 10)
//[...]
@IBOutlet var firstPokemonHealthBar: NSProgressIndicator!
//[...]
var firstPokemonOriginalHP:Float = 0

var secondPokemon:Pokemon = Pokemon(name: "Pikachu", level: 90, HP: 300, power: 13)
//[...]
@IBOutlet var secondPokemonHealthBar: NSProgressIndicator!
//[...]
var secondPokemonOriginalHP:Float = 0

初始化:

func applicationDidFinishLaunching(aNotification: NSNotification?)
{

    firstPokemonOriginalHP = firstPokemon.HP
    secondPokemonOriginalHP = secondPokemon.HP
}

更新(每次攻击后调用)

func update(str:String)
{
    if firstPokemon.HP < 0 {firstPokemon.HP = 0}
    if secondPokemon.HP < 0 {secondPokemon.HP = 0}


    //firstPokemonName.stringValue = firstPokemon.name
    //firstPokemonLevel.stringValue = "Level: " + String(Int(firstPokemon.level))
    //firstPokemonHP.stringValue = "\(Int(firstPokemon.HP))/\(Int(firstPokemonOriginalHP))hp"
    firstPokemonHealthBar.doubleValue = Double(firstPokemon.HP/firstPokemonOriginalHP)
    //firstPokemonPicture.image = NSImage(named: "\(firstPokemon.name)")
    //firstPokemonPicture.image.size = firstPokemonPicture.bounds.size

    //secondPokemonName.stringValue = secondPokemon.name
    //secondPokemonLevel.stringValue = "Level: \(Int(secondPokemon.level))"
    //secondPokemonHP.stringValue = "\(Int(secondPokemon.HP))/\(Int(secondPokemonOriginalHP))hp"
    secondPokemonHealthBar.doubleValue = Double(secondPokemon.HP/secondPokemonOriginalHP)
    //secondPokemonPicture.image = NSImage(named: "\(secondPokemon.name)")
    //secondPokemonPicture.image.size = secondPokemonPicture.bounds.size

    //TextBoxInfos.stringValue = str

    if firstPokemon.HP <= 0 || secondPokemon.HP <= 0
    {
        button1.enabled = false
        button2.enabled = false
        battleEnded()
    }
}

好的 NSLevelIndicator 工作了! 我只需要确保每个条形图的“样式”都是连续的，并且最大值是 1 而不是预定义的 2。谢谢让·巴蒂斯特
