After amusing ourselves with the many gameplay and developer videos from Media Molecule's LittleBigPlanet, it would be nice to find out a little about the mechanics behind the upcoming PlayStation 3 platformer. Fortunately, technical director Alex Evans recently outlined some of the dynamic gameplay and AI mechanics used in the game.

To give an example of how much freedom players will be getting when they design their own platformer stages, Evans explained that they will not be getting any pre-made enemies to fill in their levels. Instead, five or six "AI brains" will be supplied to give all your creations life.

In addition, several sound objects will also be available to freely litter your world. These objects can be played at specific points and give your level a pseudo-rhythm game feel to it. By going through each portion of the level at standard intervals, a Sackboy can play these sound objects in perfect timing.

One of the most dynamic game physics that will be introduced into LittleBigPlanet is perhaps the ability to use actual water physics into your creations. Evans explained that while they haven't showcased any demos using liquids, it will be included in the game if people want it.

After you're done designing your level (don't forget to take a screenshot of it!), you can save a "blueprint" of any of your creations and upload them to other gamers. These blueprint objects can even be used to associate other objects with leaderboard requirements. Any takers who do well on your levels can be rewarded by any of your blueprints as a special trophy prize.

Evans was also able to cover several other points, which were discussed in the source link we've provided below. Feel free to visit the site if you're interested in finding out more about the neat features in LittleBigPlanet. The game is slated to be released this Fall. In any case, we'll be sure to keep an eye out for more updates on it before then.
