EditorGUI.showMixedValue

static var showMixedValue : boolean

Description

Makes the following controls give the appearance of editing multiple different values.

This is sometimes useful when creating custom editors and you want to represent a value in a non-standard way in the GUI while also supporting multi-object editing.

// This example shows a custom inspector for an object "MyVessel".
// MyVessel has a boolean variable isFast but we want to show it
// as a dropdown instead of as a toggle.

enum SpeedOption { Slow, Fast }

@CustomEditor (MyVessel)
@CanEditMultipleObjects
class MyVesselEditor extends Editor {
var isFastProp : SerializedProperty;

function OnEnable () {
isFastProp = serializedObject.FindProperty ("isFast");
}

function OnInspectorGUI () {
serializedObject.Update ();

// Show the isFast boolean the standard way - as a toggle:
EditorGUILayout.PropertyField (isFastProp);

// Show the isFast boolean as a dropdown using the SpeedOption enum defined above:

// Check if the value was changed inside this block
EditorGUI.BeginChangeCheck ();

// If the isFast property represent multiple different values, the dropdown should show that:
EditorGUI.showMixedValue = isFastProp.hasMultipleDifferentValues;

// Convert the isFast boolean to an enum value
var speedOptionEnumValue : SpeedOption;
if (isFastProp.boolValue == true)
speedOptionEnumValue = SpeedOption.Fast;
else
speedOptionEnumValue = SpeedOption.Slow;

// Present the enum value in a dropdown:
speedOptionEnumValue = EditorGUILayout.EnumPopup ("Speed", speedOptionEnumValue);

// Set showMixedValue to false so it doesn't affect the following controls, if any:
EditorGUI.showMixedValue = false;

// If the value was changed inside this block, apply the new value to all the objects:
if (EditorGUI.EndChangeCheck ())
isFastProp.boolValue = (speedOptionEnumValue == SpeedOption.Fast ? true : false);

serializedObject.ApplyModifiedProperties ();
}
}

// This is the MyVessel script used above

var isFast : boolean = false;

function Update () {
// Update logic here...
}
