按下切换按钮时更改背景 [英] Change background of toggle button when it is pressed

问题描述

我看到在此问题上已经存在一些问题，但是他们没有使用unity3d或使用旧的UI unity方法.

I see there is already some questions on this matter, but they are not using unity3d or are using the old UI method of unity.

我有一个具有特定背景的切换按钮，并且我希望在关闭切换时更改背景.我尝试使用检查器执行此操作，并设置了一个功能，以在关闭按钮时将不同的纹理应用于按钮，但没有用.

I have a toggle button with a specific background and I want that background to change when the toggle is off. I tried to do this using the inspector and setting a function to apply a different texture to the button when it was off, but did not work.

您对如何实现此目标有任何想法吗?我附上我尝试过的东西.

Do you have any idea on how to accomplish this? I am attaching what I tried.

推荐答案

切换的背景只是Image

就这么简单，在脚本中有

so it's this simple, in a script have

public Image theBackground;

然后您可以按自己希望的任何方式更改它！

you can then change that in any way you wish!

如有需要，请提供功能

public Image theBackground;
public Toggle theToggle;
 public void ChangeBackground()
  {
  if (theToggle.isOn)
      ... set theBackground as you wish ..
  else
      ... set theBackground as you wish ..
  }

可对其进行适当设置.查看切换开关，然后将该函数拖动到OnValueChanged.

which sets it appropriately. Look in the toggle and drag that function to the OnValueChanged.

享受！
