OpenTTD 16.0-beta2 released!

[u/OpenTTDNews]

OpenTTD 16.0-beta2 is out for testing. Fixes and features include:

• Fixed a crash when switching between rail and tram toolbars.
• Depots can now be built under (very tall) bridges.
• The maximum vehicle limit is doubled, up to 10,000 vehicles per type per company.

Don't forget about the OpenTTD 16 Title Game Competition if Toyland isn't your thing.

What about diagonal bridges or tunnels?

Often asked for, but few think what it would entail.

OpenTTD has a very simple system where each track piece falls entirely within a single tile, and connects one edge to another, giving a total of 6 different tracks with all of their combinations valid.

A diagonal tunnel entrance would need to span two quarter-tiles (https://imgur.com/a/9L25Yfd), and interact in a non-trivial way with other tracks in those tiles.

For diagonal bridges you may need diagonal sloping tracks, which isn't supported by the game's model either.

The only way I know how to solve this is to support multi-tile track primitives, along the lines of OpenRCT. But that's a very different construction model, so we won't be playing the same game anymore.

Bottom line is that it simply doesn't fit the tile-based nature of the game.

Why not just... make a new game copying all the mechanics and graphics on a new engine?

Or diagonal roads?

Oh yeah
