Hi, I use an asset that detects the size of the game view. It uses the code below. That does work in 5.3 but not in 5.4b1 anymore. I played a bit but could not figure out the correct signature. I guess it changed due to the zoomable additions. What would the new code need to look like now? Code (CSharp): System.Type T = System.Type.GetType("UnityEditor.GameView, UnityEditor"); System.Reflection.MethodInfo GetSizeOfMainGameView = T.GetMethod ("GetSizeOfMainGameView", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static); System.Object Res = GetSizeOfMainGameView.Invoke (null,null); return (Vector2) Res; The third line will throw the error: "NullReferenceException: Object reference not set to an instance of an object"
