 ** Description
 
 This script allows you to create splash screens using events. When the player
 launches your game, a special "splash screen map" will be loaded and start
 running.

 You can use events in this splash screen map to set up your opening sequences,
 such as any splash screens using "show picture" events, animations, messages,
 screen fade-in fade-out effects, and so on.

 You can create unique splash screens with no scripting knowledge required!

--------------------------------------------------------------------------------
 ** Installation
 
 In the script editor, place this script below Materials and above Main

--------------------------------------------------------------------------------
 ** Usage 
 
 In the configuration, set the ID of the map you want to designate as the
 splash screen map, and then just set up your scene in the selected map.
 
 If you want to set the camera to a particular position, create an event
 and set its name to "START"
 
 You can create a "skip" button for players to skip the splash screen in
 the configuration.
 
 To finish the scene and go to the title scene (or another scene),
 make the script call
 
   SceneManager.goto(Scene_Title)
