SplashScreen

TODO:

  • Test allot of things. this is a very early version.
  • Fade the background color out.
  • Currently what is fading is a solid color, what's better is to fade the splash screen image itself.

Any additions to this script are always welcome!

Just create a new scene with a camera and empty gameobject. Add the script to the gameobject and set properties (nextlevel and logo)

Code

// // SplashScreen Script // // Version 0.1 by Martijn Dekker // martijn.pixelstudio@gmail.com // // Version 0.2 by Ferdinand Joseph Fernandez, 2010Sep7 16:45 GMT + 8 // Changes: // * changed levelToLoad to a string, for easier usage // * added waitTime, which adds a pause after fade in, and before fade // out (during fade waiting) // * added option to either automatically fade out after waitTime // seconds (default), or wait for user input (press any key to continue) // * added option to wait until fade out is complete before loading next // level, instead of the default, which is to load the next level // before fade out //
