Question Add Game View Resolution Programatically (old solution doesn't work)

Hello! I found this solution : https://answers.unity.com/questions...96.915528479.1585746941-2112408147.1582032419
It works when i change resolution in playmode, but it throws NullReferenceException when trying to add a new resolution in playmode.
An error occurs when the GameViewSize constructor is called, although the constructor is present.

Code :

Code (CSharp):

1.  public static void AddCustomSize(GameViewSizeType viewSizeType, GameViewSizeGroupType sizeGroupType, int width, int height, string text)
2.     {
3.         // goal:
4.         // var group = ScriptableSingleton<GameViewSizes>.instance.GetGroup(sizeGroupType);
5.         // group.AddCustomSize(new GameViewSize(viewSizeType, width, height, text);
6.  
7.         var asm = typeof(Editor).Assembly;
8.         var sizesType = asm.GetType("UnityEditor.GameViewSizes");
9.         var singleType = typeof(ScriptableSingleton<>).MakeGenericType(sizesType);
10.         var instanceProp = singleType.GetProperty("instance");
11.         var getGroup = sizesType.GetMethod("GetGroup");
12.         var instance = instanceProp.GetValue(null, null);
13.         var group = getGroup.Invoke(instance, new object[] { (int)sizeGroupType });
14.         var addCustomSize = getGroup.ReturnType.GetMethod("AddCustomSize"); // or group.GetType().
15.         var gvsType = asm.GetType("UnityEditor.GameViewSize");
16.  
17.         var types = new Type[] { typeof(GameViewSizeType), typeof(int), typeof(int), typeof(string) };
18.         // in original
19.         // var types = new Type[]{typeof(int), typeof(int), typeof(int), typeof(string)};
20.         // throws exception too
21.  
22.         var ctor = gvsType.GetConstructor(types);
23.  
24.         // throws exception here
25.         var newSize = ctor.Invoke(new object[] { viewSizeType, width, height, text });
26.         // in original
27.         // var newSize = ctor.Invoke(new object[]{(int)viewSizeType, width, height, text});
28.         // throws exception too
29.  
30.         addCustomSize.Invoke(group, new object[] { newSize });
31.  
32.         sizesType.GetMethod("SaveToHDD").Invoke(gameViewSizesInstance, null);
33.     }

This code worked for Unity 2018!

public static void AddCustomSize(GameViewSizeType viewSizeType, GameViewSizeGroupType sizeGroupType, int width, int height, string text)
{
var group = GetGroup(sizeGroupType);
var addCustomSize = getGroup.ReturnType.GetMethod("AddCustomSize"); // or group.GetType().
var gvsType = typeof(Editor).Assembly.GetType("UnityEditor.GameViewSize");
string assemblyName = "UnityEditor.dll";
Assembly assembly = Assembly.Load(assemblyName);
Type gameViewSize = assembly.GetType("UnityEditor.GameViewSize");
Type gameViewSizeType = assembly.GetType("UnityEditor.GameViewSizeType");
ConstructorInfo ctor = gameViewSize.GetConstructor(new Type[]
{
gameViewSizeType,
typeof(int),
typeof(int),
typeof(string)
});
var newSize = ctor.Invoke(new object[] { (int)viewSizeType, width, height, text });
addCustomSize.Invoke(group, new object[] { newSize });
}

thank you for your sharing. Follow you code, I can add new resolution by fixed resolution (width and height) but I can not find the way to add new resolution by aspect ratio. Can you help me? Thanks

 

instead
object entry = constructorInfo.Invoke(new object[] { 1, width, height, label });
put
object entry = constructorInfo.Invoke(new object[] { 0, width, height, label });
