Core Coding Standard

Coding practices are a source of a lot of arguments among programmers. Coding standards, to some degree, help us to put certain questions to bed and resolve stylistic debates. No coding standard makes everyone happy. (And even their existence is sure to make some unhappy.) What follows are the standards we put together on the Core team, which have become the general coding standard for all programming teams on new code development. We’ve tried to balance the need for creating a common, recognizable and readable code base with not unduly burdening the programmer with minor code formatting concerns.

	Howdy!

	I wrote Red Faction''s Geomod engine...

	It does a complete realtime subtractive boolean from the world Geometry. The "hole" that is cut out is a loaded mesh that gets randomly rotated to look different everytime. It could be any shape, we just liked how this one worked. It operates on a face basis, splitting some, deleting some, and adding in new ones. The input is a polygon mesh; the output is a polygon mesh.

	The math to to the boolean takes place spread out over a few frames so that it doesn''t impact framerate much.

	All of out structures in the game are dynamic to handle this... the code to actually make the whole is only a minor part of the problem. For instance, our AI paths can update to reflect the hole, the rooms and portals update so a hole between two rooms is now a portal, and the collision detection structures for the world use recursive AABB, which get dynamically updated during the Geomod. Even things like slapping bullet decals on the new faces and making sure to remove decals on fa
