Elysion is a cross-plaform (currently supporting Windows, Linux and Mac OS X) framework for creating games with ease and is therefore suited for rapid prototyping.

Elysion has been more or less regurarly in development since 2005 and has been created by Johannes Stein.

Thanks to anyone who used (or whom I forced to use ;) ) this framework. This
framework would not exist in its current form without those people:

• Sven Rech (Initial Linux testing)
• David Herzog (Early sprite lists and in general a very helpful guy)
• Jesse Klugmann
• Christian Fuchs
• Arthur Baude
• Dominique Louis (He made SDL bindings for Object Pascal)
• Sam Lantinga (The creator of SDL)

Also thanks to these pieces of software which inspired me:

• Irrlicht 3D Engine
• Horde 3D / Horde 3D GameEngine
• Gosu
• Unity3D

Elysion is designed to be high-level with its API to be very simple and intuitive.
Here is a chunk of code which loads a sprite, displays the sprite and randomly
changes its color with each click.

var mySprite: TelSprite;

mySprite := TelSprite.Create;
mySprite.LoadFromFile('mySprite.png');

mySprite.Draw;

if (mySprite.Click) then
begin
  Randomize;
  mySprite.Color.R := Random(255);
  mySprite.Color.G := Random(255);
  mySprite.Color.B := Random(255);
  // Alternative you could also write: mySprite.Color := makeCol(Random(255), Random(255), Random(255));
end;

Elysion is dual-licensed under the MIT and MPL license. Choose which one you like the most or use both if you feel like it.

Be careful though: Other third-party libraries included in this package (in /lib/Dependencies) may use a different license.
