Well I went in to the Custom Games area after the update: ( UI )
-
Clicked on Custom Games.
-
Clicked on maps, Selected Map
-
Clicked on Games Modes
-
Then selected “My Files Area”
It was really good to see my custom modes pop up fast. That was really nice to see. Thanks 343i
I figured out a Mickey Mouse way to get my CAPTURE THE FLAG custom game mode to work. ( still cant edit game modes and saved game modes after shutting down the game. )
NOTE: ( I have 50 changes in my CTF game mode )
Now I think is a transitions issue here is why:
You know that on the top right hand corner your user name pops up and it sez your online. Now when I try to run my game mode it won’t connect to the MS Game Servers.
BUT!!!
If I go to server and go off line the game works great! Here is what I have to do to go connect to the MS Azure Game Servers.
-
Select Map
-
Select Game Mode ( My edited CTF Game Mode )
-
Select Server
-
Go Offline
-
Click Play
-
When the game started Select LEAVE GAME!
-
As fast as you can goto server select XBOX the Click PLAY
Side Note: You can only do this while you user name is showing in the top right hand corner!!!
If your user name disappears then you click on play, YOU WILL NOT CONNECT to those MS AZURE SERVER!!
That is why I feel it’s a transitions issue with my edited Custom Game Mode!
Peace!
