(WARNING: This is a dev scratchpad to collect ideas for a newroute grf system)
This page is for collecting ideas for newroads (Lakie) and enhancetunnels(eis_os)
to get a united system for allowing more flexible sprite content = newroutes
-=Action 0=-
All TTD routes get devided into logical groups:
For roads:
||ID|Description|Default Number Of Sprites Needed
00|roads|19 (4 halfs, 4 slope, 2 straight, 4 corners, 5 junctions)
01|road depot|6 (4 roofs, 2 little corner pieces)
02|road crossing ground|2
03|road pieces on bridges|2|
04|road tunnel rail ground|4
05|road tunnel|8||
For rails:
||ID|Description|Default Number Of Sprites Needed
00|railroad|?
01|monorail|?
02|maglev|?
03|electric|?(shared with railroad!)

Type 4 till type 7 are fair game for grf authors.
Action 0 for first 8 rail ids:
- names
- compatible mask for rails, aka rail type 3(electric) is compatible to 0 (via or mask)
- system flags, will draw catenary, makes electrif traction engines work, copy of action 0(train) traction type?
Action 0 for railvehicles:
- a flag for supporting newroutes
- need a new way to have the real type specifc
(sample an narrow gauge isn't allowed to work on normal rail, but doesn't depend anymore on maglev)
Action 0 has to support for each of the above IDs, serveral standard/default layouts and custom layouts. The custom layouts can be used for more advanced stuff and are selectable via action 2 callback.
How drawing works:
TTDPatch will use a callback (if enabled for id) to get a spritelayout number.
If not, it will use the default number for the layout.
Get Ground Sprite, dword 0 for none
Draw normal sprites until we find 80h (as stations)
Each entry allows some special bit settings in the spritenumber.
(sprite number in recent action 0, TTD Sprite, Special Sprite from other ID !)
-=Action 2=-
Variational Action 2 Variables for New Routes
||Variable|Content
80|Height above ground
81|Terrain type: 0 normal, 1 desert, 2 rainforest, 4 on or above snowline
82|Townzone: 0 none
83|Is under bridge
84|Build year (problem where to store that info)||
-=Landscape 8=-
For each tile it would be nice to store the buildyear, maybe year / 10 for support later years, post 2010... = L8 Array.
-=Compatibility=-
The new rail stuff is incompatible to the old, unimaglev could be used to have old games fit to the new system,
or not convert old games and tell the newroutes we work an old version and cross convert on the fly the systems.
-=Other=-
