Question

嘿大家我是C＃的新手，我遇到了一些问题。我现在正在为学校做一份工作，我真的被这部分困住了。我盯着它，谷歌搜索几个小时，我有运气。我已经在下面列出了我到目前为止的内容。

方向不是那么好。

“为4种图像状态创建公共枚举CharacterState：攻击，防御，空闲和死亡。现在创建一个成员变量状态来保存字符状态和一个带有get的公共属性State 并设定。现在，填写get的默认行为并设置为return / set state of state。“

任何帮助都会受到很大的限制！谢谢

namespace WPFBattle
{
    class CharacterImage: System.Windows.Controls.Image
    {
        public enum Attacking{

        }

        public enum Defending{

        }

        public enum Idle{

        }

        public enum Dead{

        }
        public ImageSource IdleImageSource { get; set; }
        public ImageSource AttackingImageSource { get; set; }
        public ImageSource TakeDamageImageSource { get; set; }
        public ImageSource DeadImageSource { get; set; }

        protected void UpdateImageSource()
        {
            switch (State)
            {
                case CharacterState.Attacking:
                    this.Source = AttackingImageSource;
                    break;
                case CharacterState.TakeDamage:
                    this.Source = TakeDamageImageSource;
                    break;
                case CharacterState.Dead:
                    this.Source = DeadImageSource;
                    break;
                case CharacterState.Idle:
                default:
                    this.Source = IdleImageSource;
                    break;
            }
        }

        protected override void OnRender(DrawingContext dc)
        {
            UpdateImageSource();
            base.OnRender(dc);
        }

        public CharacterState State
        {
            get { return state; }
            set
            {
                state = value;
                this.Dispatcher.Invoke((Action)(() =>
                {
                    UpdateImageSource();
                }));
            }
        }
    }
}

从你的枚举开始。

为4种图像状态创建公共枚举CharacterState：攻击，防御，空闲和死亡......

从您的代码中，您为每个州创建了一个枚举。枚举对于定义选项很有用，在你的情况下，你应该有一个定义你的角色状态的枚举。

viewForFooterInSection

...现在创建一个成员变量状态来保存字符状态，并使用get和set创建一个公共属性State。

if self.didTapOnButton == true {
    DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
        self.view.layoutIfNeeded()
        UIView.animate(withDuration: 0.3, animations: {
            bubbleView.backgroundColor = UIColor(red: 255/255, green: 225/255, blue: 68/255, alpha: 1)
            containerViewTrailingConstraint.constant = 5
            iconImageViewTrailingConstraint.constant = 5
            bubbleViewEqualWidthConstraint.constant = 0
            self.view.layoutIfNeeded()
        }, completion: { (done:Bool) in
            UIView.animate(withDuration: 0.2, animations: {
                textView.alpha = 1
                doneButton.alpha = 1
            }, completion: { (done:Bool) in
                textView.becomeFirstResponder()
            })
        })
        self.didTapOnButton = false
    }
}

然后，您可以通过State属性访问角色的当前状态。

public enum CharacterState {
    Attacking,
    Defending,
    Idle,
    Dead
}

希望这能澄清事情。

Answer 2

你的枚举声明错了。这就是你想要的。

enum CharacterState
{
    Attacking,
    Defending,
    Idle,
    Dead
}

class CharacterImage 
{

    private CharacterState state;
    public CharacterState State
    {
        get { return state; }
        set
        {
            if (state == value)
                return;

            state = value;               
        }
    }
}

您也可以将您的房产写为..

public CharacterState State { get; set; }

这可以编译与上述属性相同的代码，除了值比较部分。

if (state == value)
    return;

Answer 3

首先，你写的语句是：为4个图像状态创建一个公共枚举。这只是一个具有4个可能值的对象。创建，然后使用属性/字段成员来管理内部值。也许，它是这样的：

    namespace WPFBattle
{
    public enum CharacterState{
        Attacking = 1,
        Defending = 2,
        Idle = 3,
        Dead
    }

    class CharacterImage: System.Windows.Controls.Image
    {

        public CharacterState _state;

        public ImageSource IdleImageSource { get; set; }
        public ImageSource AttackingImageSource { get; set; }
        public ImageSource TakeDamageImageSource { get; set; }
        public ImageSource DeadImageSource { get; set; }

        protected void UpdateImageSource()
        {
            switch (_state)
            {
                case CharacterState.Attacking:
                    this.Source = AttackingImageSource;
                    break;
                case CharacterState.TakeDamage:
                    this.Source = TakeDamageImageSource;
                    break;
                case CharacterState.Dead:
                    this.Source = DeadImageSource;
                    break;
                case CharacterState.Idle:
                default:
                    this.Source = IdleImageSource;
                    break;
            }
        }

        protected override void OnRender(DrawingContext dc)
        {
            UpdateImageSource();
            base.OnRender(dc);
        }

        public CharacterState State
        {
            get { return _state; }
            set
            {
                _state = value;
                this.Dispatcher.Invoke((Action)(() =>
                {
                    UpdateImageSource();
                }));
            }
        }
    }
}

Answer 4

public enum CharacterState {
    Attacking,
    Defending,
    Idle,
    Dead
}

public class Character {

    public Character()
    {
        State = CharacterState.Idle;
    }

    private CharacterState state; //-Member variable (private)

    public CharacterState State 
    {  get
       {
            return state; // note the casing in State and state
       }  
       set
       {
           State = value;
       }
}
