Page 7 - Further Development - Where do we go from here?

The only real change that needs to be made is rectifying the trace situation, so that the portals themselves spawn the new traces to save us having to re-code every trace weapon just to use this system (after all, we don't need to re-code every projectile to work with WarpZones).

Other smaller issues include fixing up the beam translation calculation as it's currently a bit off, working out how to deal with that gap along the sides of the zones between the portals and the blocking volumes, and seeing if there are any better ways of cutting up the levels, so that objects can't collide with the edges of the inner cube itself. In comparison to the issues that we started with, these are tiny and could almost be forgotten, but I'll keep at it eventually.

So, how easy is this to work with? It's as simple as cut and paste. Once all of this has been set up once, we just need to move the entire cube, all portals and all blocking volumes from one level and place them in another, resizing the entire portal setup if necessary (for larger/smaller levels). As proof, I took DM-Plunge and made it work recursively. These are old shots of the level before I made the portals clearer, but it works.

This system is also present within the game of Metamorphosis that I worked on during the university semester. You'll see more of it in practice over on the page for that.

Thanks for reading, a downloadable version will be made available shortly.
