I recieved another email regarding Flock from proper games, seems not much of the cube engine is left.
Flock itself does not have any parts of the cube engine remaining unfortunately, but yes it is indeed possible to get the cube engine up and running on xbox and PS3 too. The game that we originally built with the cube engine was converted and working on both platforms. This was done by abstracting away all the rendering calls. This then allows you to write multiple renderers underneath depending on the platform you aim at. I didn’t do the abstracting process personally but it was quite involved and some parts of the engine needed heavy rewrites to allow us to do it.
After all the conversion work to the cube engine, the only thing remaining was the octree cube rendering and editing. The abstraction layer pretty much became our in-house tech. On Flock we went for a custom modular system of level building that we created ourselves (and included the level editor in the game) so we didn’t use the cube engine at all in the end.
So in short yes, with a fair chunk of work you can build the cube engine for consoles. Just bear in mind that the actual cube generation and editing is all that’s really left, and we converted the engine 6 years ago, I have no idea how it has progressed since then.
I hope that’s of some use to you, let us know if we can get a sneaky peek of the mech game, it sounds interesting
