From model to world

Model it.
Play it.

Orbliterate! is a game first, and you can enjoy every course in it without building anything. But its worlds are made from parametric CAD, which is short for computer aided design, and a scripting system called Typescript. Both are open for players to make use of.

The shapes in a level come from CAD parts, which are straightforward to design. Behavior comes from scripts, which give a course real interaction with the player. You can take on either one by itself, and each builds a skill worth having well beyond the game. What you get for practicing them is a world other people can play.
