Question

我愿意通过C＃中的代码更改按钮状态（按下，取消激活，突出显示）。就像某些动作一样，我想将按钮状态切换为deactive。我怎么能这样做？

我尝试设置按钮状态，但我没有找到任何属性接受spriteState。我试图通过这个

设置禁用状态

        public Sprite activeBtnState;
        public Sprite deactiveBtnState;//button disable sprite that will be applied
        public Button BtnToChange;//button whoes state require to change

        public void NavigationTask() {
         if (isBtnActive)
                    {
                        BtnToChange.interactable = false;
                        BtnToChange.spriteState.disabledSprite = deactiveBtnState;
                    }
                    else
                    {
                        BtnToChange.interactable = true;
                    }
              }

错误11无法修改返回值 'UnityEngine.UI.Selectable.spriteState'因为它不是变量

此外是否有任何内置功能（功能）可自动更改我的按钮状态，而且我不编写代码来管理精灵？

Answer 1

答案在documentation：

//Creates an instance of a sprite state (This includes the highlighted, pressed and disabled sprite.
// Assign the sprites in edit mode
public SpriteState sprState = new SpriteState(); // <- IMPORTANT DECLARATION
public Button BtnToChange;

// You can even change the transition type
public Selectable.Transition transition ;

 public void NavigationTask()
 {
     if (isBtnActive)
     {
         BtnToChange.interactable = false;
         BtnToChange.spriteState = sprState ; // <- IMPORTANT LINE
     }
     else
     {
         BtnToChange.interactable = true;
     }
 }

您可以使用Button.interactable更改Button州。

禁用：

BtnToChange.interactable = false;

启用：

BtnToChange.interactable = true;
