bool 如果在调用 EditorGUI.BeginChangeCheck 后 GUI 状态发生更改,则返回 true,否则返回 false。
结束代码块并检查是否有任何 GUI 更改。
将它与 EditorGUI.BeginChangeCheck 结合使用来创建一个代码块,检查是否只有代码块中包含的控件的 GUI 状态发生了更改。
也就是说,此方法允许将检查限制为一组特定的控件,这一点不同于对于 GUI 状态的“任何”更改都返回 true 的 GUI.changed。
using UnityEditor;
public class ExampleWindow : EditorWindow { float sliderValue = 0; string labelText = "-";
[MenuItem("Window/Example Window")] static void Init() { var example = (ExampleWindow)EditorWindow.GetWindow(typeof(ExampleWindow)); example.Show(); }
void OnGUI() { EditorGUILayout.LabelField("New value", labelText);
// Start a code block to check for GUI changes EditorGUI.BeginChangeCheck();
sliderValue = EditorGUILayout.Slider(sliderValue, 0, 1);
// End the code block and update the label if a change occurred if (EditorGUI.EndChangeCheck()) { labelText = sliderValue.ToString(); } } }
