Basic railroad track map tiles

[Wuzzy2]

This adds some new terrain types and (over)map tiles to C:DDA. Those are all railroad-related.

New terrain types are: railroad tie (several directions), railroad track, buffer stop, railway crossing signal, crossbuck (wooden or metal).
New map tiles are: Straight rail, curved rail, rail ending with buffer stop, railway crossing (with crossbuck or railway crossing signal) and 2 kinds of railroad bridges.
The railway crossing signal, buffer stop and the crossbucks are smashable for wood or metal. The signal drops cheap electronics.

A (not accurate anymore) preview is here: http://smf.cataclysmdda.com/index.php?topic=5678.msg103528#msg103528

Please note there are no junctions for railroad tracks; these have been blacklisted.

To test, open the debug menu’s map editor and try everything with the word “rail” in it.

This is amazing!

Good work!

One thing I notice is that the railroads themselves are not disassemblable
for rails.

Rails, of course, are extremely powerful ammo for railguns.

@dwarfkoala: I had this idea, too. But I don’t know how to disassemble terrain or if this is even possible.

Railguns are named that because they are constructed of electrical rails that carry current to accelerate the projectile, not because they use railroad rails as ammo. Also a railroad rail weighs over 100 pounds - the spikes used to nail the rails to the railroad ties would be MUCH better ammunition - those weigh something like 8 to 12 ounces each...

So this adds map tiles but it doesn't actually spawn them?

Would probably use the same general mapgen code as river generation, I'd think, since rail junctions are Out.

This looks very impressive. Is it going to see some use in those subway/metro tunnels? I always found it awkward that those tunnels had no metal in them.

I hope we also get simple junctions/crossings in future development, perhaps dynamically generated by just overlaying the pieces. Proper junctions/switches need a lot of effort to implement believably and can wait.

@Rivet-the-Zombie: Yes. I leave the task of map generation to others. :P xD

Unfortunately we don't merge code that doesn't actually do anything. You've come this far: you're gonna need to take another step and work it into mapgen somehow. Feel free to look at the code for subway lines and rivers; those are probably the closest fits. I got my start from copying and creatively reusing existing code. It's an entirely valid way to learn.

As a more accessable alternative to trying to solve the (fairly difficult)
someone can make a railyard or similar environment. Also this doesn't
conflict with anything, so it can hang out as a PR and probably not
accumulate conflicts until someone does work it in.

[Wuzzy2]

I added “[WIP]” to the title because the inclusion to the map generator is missing.

[Coolthulhu]

This PR will probably not become mergeable. Closing.

[Rivet-the-Zombie]

But the idea was solid. I'd love to see this concept revisited and completed.
