Check if any control was changed inside a block of code.

When needing to check if GUI.changed is set to true inside a block of code, wrap the code inside a ChangeCheckScope like this:

using UnityEditor;

class ExampleClass { void ExampleMethod() { using (var check = new EditorGUI.ChangeCheckScope()) { // Block of code with controls // that may set GUI.changed to true

if (check.changed) { // Code to execute if GUI.changed // was set to true inside the block of code above. } } } }


changedTrue if GUI.changed was set to true, otherwise false.


EditorGUI.ChangeCheckScopeBegins a ChangeCheckScope.
