Zexion made me aware that the little launcher I made was not always successful for him, so I made a new variation of it. It uses a different way of accomplishing the same end result. I don't know which way most will prefer, as this variation requires renaming the existing Game.exe and Game.ini, but I have tested it every-which way I know how, and it seems to work consistently.
Step 1Rename both "Game.exe" and "Game.ini" to anything other than "Game", but their names must be the same with the exception of the file extension. Example: "My Awesome Game.exe" and "My Awesome Game.ini"
Step 2Download the launcher and place it within the game directory.
Step 3Run the game using the launcher
This will allow you to run the game normally by either using the launcher, or playtesting via the editor (you should not have renamed "Game.rxproj"). The editor searches for Game.exe, so this method of doing requires the launcher to have the name Game.exe, but it does seem to work better. Arguments passed to the launcher are passed to the default Game.exe, so you will still have DEBUG set when running from the editor.
