Looking for a graphical for Maglev Enhanced Tunnels

[WWTBAM]

As some TTDPatch players know, the sprites used by the other 3 default rail types can't be used for maglev enhanced tunnels. I was looking for ideas how to graphically solve the issue. These would need to go into ttdpbase(w).grf which I will attempt to implement in the patch.

Maybe Snail could come up with something interesting? I remember he also did the default graphics for OTTD´s railtype tunnel portal overlays.

I am thinking I will need a set of sprites that mimic the default ground tile for a maglev junction without the grass surrounding the concrete trough. Then I can have TTD draw the sprites that were orriginaly used on top to show the direction of track.

I'm not quite sure, what you want to do, but Canadian (BK) Tunnels do contain maglev tunnels (including normal, monorail and roads too) for enhanced tunnel functionality for all climates and matching TTD 'original' terrain graphics.

http://www.tt-forums.net/viewtopic.php? ... 0#p1042960 shows the current situation. I will post a screenshot of the previous situation tomorrow when I'm back on my laptop.A nightly before r1447 should display the old behavior.

Here is a screenshot of what the user used to get when building a straight track with r1446. I cant demonstrate corners on a tunnel as that hadn't been implemented then.

How are these?

They look good wallyweb. Now to work out how to implement code to draw them from ttdpbase(w).grf rather than trg1(r).grf. Any help from a TTDP dev would be greatful.
edit: added the last sentence.

Well, yes, I did come up with new tunnel portals for highspeed lines:

They're still unreleased though. They will be part of the rails for the French set, as the TGV line's tunnel portals.

From memory, enhanced tunnels only draws the normal track sections on top of the the tunnel and doesn't use special sprites for those tunnels, as such, I believe that particular issue is actually a bug within the enhanced tunnels patch.

[Edit] After looking through the code it looks like it uses a tunnel sprite (which is obviously straight) for maglev as none of the default TTD sprites (1169 - 1174) are suitable for drawing above the tunnel. It might be necessary to write in support for new maglev enhanced tunnel top sprites and draw those as the solution.

That was what I was hoping to do, ie draw wallyweb's sprites instead of the TTD sprites since the enhanced tunnels code handles maglev differently to the other railtypes and there is a block of code for directions other than / and \that currently just draws the same sprite for | _ views. Maybe I should ping JGR and see if he's interested as he did the prep work for different maglev sprites.
