编辑器中的全屏模式游戏视图

Question

I am trying to make my game view full screen and I have found few scripts online in order to achieve this. Unfortunately I am not able to execute them in 2020 version (or 2018+). Is there a method to enable full screen game window during editor mode? From the below script, I get exception error at System.Object Res = GetMainGameView.Invoke (null, null); Is the current Unity version not accessible for the GetMainGameView?

using UnityEditor;
using UnityEngine;

namespace FullScreenPlayModes {
    [InitializeOnLoad]
    public class FullScreenPlayMode : Editor {
        //The size of the toolbar above the game view, excluding the OS border.
        private static int toolbarHeight = 22;

        static FullScreenPlayMode () {
            EditorApplication.playModeStateChanged -= PlayModeStateChanged;
            EditorApplication.playModeStateChanged += PlayModeStateChanged;
        }

        static void PlayModeStateChanged (PlayModeStateChange _playModeStateChange) {
            if (PlayerPrefs.GetInt ("PlayMode_FullScreen", 0) == 1) {
                // Get game editor window
                EditorApplication.ExecuteMenuItem ("Window/General/Game");
                System.Type T = System.Type.GetType ("UnityEditor.GameView,UnityEditor");
                System.Reflection.MethodInfo GetMainGameView = T.GetMethod ("GetMainGameView", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static);
                System.Object Res = GetMainGameView.Invoke (null, null);
                EditorWindow gameView = (EditorWindow) Res;

                switch (_playModeStateChange) {
                    case PlayModeStateChange.EnteredPlayMode:

                        Rect newPos = new Rect (0, 0 - toolbarHeight, Screen.currentResolution.width, Screen.currentResolution.height + toolbarHeight);

                        gameView.position = newPos;
                        gameView.minSize = new Vector2 (Screen.currentResolution.width, Screen.currentResolution.height + toolbarHeight);
                        gameView.maxSize = gameView.minSize;
                        gameView.position = newPos;

                        break;

                    case PlayModeStateChange.EnteredEditMode:

                        gameView.Close ();

                        break;
                }
            }
        }

        [MenuItem ("Tools/Editor/Play Mode/Full Screen", false, 0)]
        public static void PlayModeFullScreen () {
            PlayerPrefs.SetInt ("PlayMode_FullScreen", 1);
        }

        [MenuItem ("Tools/Editor/Play Mode/Full Screen", true, 0)]
        public static bool PlayModeFullScreenValidate () {
            return PlayerPrefs.GetInt ("PlayMode_FullScreen", 0) == 0;
        }

        [MenuItem ("Tools/Editor/Play Mode/Window", false, 0)]
        public static void PlayModeWindow () {
            PlayerPrefs.SetInt ("PlayMode_FullScreen", 0);
        }

        [MenuItem ("Tools/Editor/Play Mode/Window", true, 0)]
        public static bool PlayModeWindowValidate () {
            return PlayerPrefs.GetInt ("PlayMode_FullScreen", 0) == 1;
        }
    }
}

Answer 1

Most people would suggest use "maximize on play button" which is not you want.

I would suggest if you want to test the look of your game in full screen just build and run after you edit Build settings/Player settings and make the game there full screen or even let use to use alt+enter to go full screen and test your look.

This will be much easier than using in game scripts just to test full screen in editor UNLESS you want to see console output while in full screen. There is also a free asset in store see the console in build.

Answer 2

I know this was asked a year ago but maybe this will be useful to someone.

If you can afford it, I recommend this asset called Fullscreen Editor. https://assetstore.unity.com/packages/tools/utilities/fullscreen-editor-69534

Alternatively, unity has a built-in package in the package manager with an editor recorder. This will automatically record your gameplay with none of the editor UI or your app bar in the way.

Or as someone else stated, make a test build or use the "maximize on play button" in the editor panel.
