Modular Wider Bridges Set

: Screenie01.png (161.45 KiB) Viewed 10608 times

This set replaces the three tubular bridges with three modular bridges that together can be used to visually make a wider bridge.
Or, via parameter, adds them as three extra bridges (JGR PatchPack only).
The middle piece could in theory also be used in combination with objects next to it (providing the sides and backs of a bridge), to make one-of-a-kind bridges.

The roadbridge has the look of the Highway from RattRoads, but will adapt to any other roadset, if that roadset provides bridge-overlay graphics.

The rail/mono/mlev-bridge has a dark grey concrete look. Vanilla rail/mono/mlev tracks will not be visible on this bridge!
Use a trackset that provides bridge-overlay graphics.

MAJOR ISSUE:
Cities and AI's will probably also build these bridges, but not as intended.

A lot of replacement may be required of the player

So this is more for the eyecandy players, rather than for regular games

Use this GRF in combination with JGR PatchPack v0.38.1 or newer and you will not have the above issue.

GRF can be found on Bananas.

The GRF mentioned below is now obsolete:
Modular Wider Bridges Set for JGR PatchPack
I have also made a version for (recent) JGR Patchpack, this will not replace, but add the three bridges.

Great idea for those who like to Eye candy their games .. I was looking some time ago doing the Sydney Harbour Bridge as modules, but didn't continue it because AI's not use it properly. Wonder some times if worth working on it again similar to what you did here.

Cheers pal

Yeah AI's and cities are the main issue, but in my games I dont let cities grow by themselves (and I will correct some strange bridges built during spawning myself if I stumble upon them) and I dont allow AI's to build anything (only for eyecandy vehicles basically).
So, this simple bridge set will work for those types of games.

But, as I mentioned, you could place objects next to the Middle bridge graphics (at the front and back, with some overlap pieces to let ships through) and so make an unique bridge...

Finally someone thought about this, well done!

Can you make a version that makes use of bridge IDs 0D through 0F in JGR's Patch Pack? I tried editing your source code but I'm hopeless with NFO.

Thats not too difficult (just did a test and it worked), but I dont know how to give those extra bridges their own icon in the purchase menu.
I have been searching around various topics (here and on Simuscape), but cant find any good clear documentation (it's something to do with adding Prop14 to Action00 and then something else that adds the realsprites).

I'll quote Wallyweb here to draw his attention as I believe he has some knowledge about this.

Go away! I'm sleeping!

Oh! Quast65 and Gadg8eer!

Bridge Action 0 Property 14 is defined in the NewGRF Specifications.
It is supported by New Map Features (NMF) and JGR's patch pack.

1. You need to use Action D GRF Resource Management (GRM) to reserve space for your sprite.
2. Next Action 6 to access the real sprites to be added/modified.
3. Next Action A to define the real sprites to be added/modified. (This also defines the sprite IDs starting at 0x00, so keep count of the real sprites you worked on)
[ sample real sprite with ID noted - this is the 191st real sprite in the Action A, so the ID is 190 or 0xBE]
241 sprites\wallywebNMFBridgeSet_0F_CarbonNano.pcx 16 528 09 11 40 0 9 //BE 190

4. Now we have another Action 6
//-------------------------------------------------------------------------------------------
// Action6 - Modifies the contents of the following sprite
358 * 5 06 20 82 06 FF // Change 2 bytes starting at position 6 of the following Action0
//-------------------------------------------------------------------------------------------
5. Followed by an Action 0 for property 14
//-------------------------------------------------------------------------------------------
// Action0 - Bridge Properties
359 * 10 00 06 01 01 0F 14 BE 00 00 00 // 01 props; 01 info; bridge Id 0F; Prop 14; spritedata;
//-------------------------------------------------------------------------------------------

Note: If you are using nforenum, it does not know about property 14 and it will throw a fatal error hissy fit. Just ignore it.

Enjoy your new menu sprite.

Next time call ahead and make an appointment with my secretary.

Wakey wakey!!

The American Bridges Set (on which my code is based) is coded slightly different than you do.

Main thing is that there are a lot of Action 0D's...
Here is the code of Bridge 0D:

I added line 109 as the Action 0D for the menu sprite
Line 110 is then that first Action 06
Then the Action 0A, with on line 216 the menu sprite
Line 217 the second Action 06
And finally line 218 the Action 00 Prop 14

But it doesnt work:

: Screenie02.png (16.46 KiB) Viewed 10272 times

It doesnt show the menu sprite anymore of one of the Tubular Bridges, so thats good

But not the good menu sprite either… Changing value 68 in line 218 gives strange results (random pieces of the actual bridge)

Any idea what could be wrong?

Posted: **14 Oct 2020 16:44**

I may be wrong about this. I haven't worked on my bridge code in over a year.

Code: Select all

//this reserves some sprites into temp. params
    5 * 9	 0D 00 \D= \DR FE FF 08 69 00 //this "main" param is used to allocate all of the graphics via the following action 6
    6 * 9	 0D 01 \D+ 00 FF 01 00 00 00 //each sprite then gets its own param # to use in the final action 6's which determine placement
    7 * 9	 0D 02 \D+ 00 FF 02 00 00 00
    8 * 9	 0D 03 \D+ 00 FF 03 00 00 00
...
...

Where is the param# for sprite 00?

Posted: **14 Oct 2020 17:14**

Code: Select all

 217 * 5	 06 20 82 06 FF
//!!Error (141): ID 0D out of valid range (00..0C).
//!!Fatal Error (47): Offset 5: Invalid property 14.

Move this to after table 6.

Posted: **14 Oct 2020 17:21**

I dunno… But it works

The only thing I understand from bridge-coding is how to replicate the code and what I need to change (ID's) to get more bridges.

Is it possible to add that menu-thing as a separate block?

So, starting with its own 0D, 06, 0A, one sprite, 06 and Action 0 prop 14?

Probably but I don't recommend it.
The reason moving it worked is that it's real sprite was the last one defined in the Action D block.
You now have something that works. Don't mess with success.

Posted: **14 Oct 2020 19:53**

Preventing towns and AI/GS scripts from building a particular bridge type is easy to implement, so I've gone ahead and added a property to do that.

A GRF which uses the extra bridge IDs, or the menu icon property, or the above property, will only work on sufficiently new patchpack versions.
Users on trunk will just get an unhelpful cryptic error (and then post bug reports, etc).

I'd suggest checking whether these are available using the feature testing mechanism described here, and then falling back to not using them or showing a nicer error message if not.

Adding this code-block at the end of every bridge-type worked (indeed, ignore the errors) :

Code: Select all

  229 * 9	 0D 00 \D+ 00 FF 00 00 00 00
  230 * 5	 06 00 02 03 FF
  231 * 5	 0A 01 01 00 00
//Bridge Icon
  232 modular_wider_bridges/gfx/gui_icons.png  8bpp  290     2    43   20   0    0 normal //bridge icon 00
  233 * 5	 06 00 02 06 FF
//!!Error (141): ID 0D out of valid range (00..0C).
//!!Fatal Error (47): Offset 5: Invalid property 14.
  234 * 10	 00 06 01 01 0D 14 00 00 00 00

In the Action0 (in this case line 234), replace 0D with 0E or 0F for the other two extra bridges)

EDIT:
I spoke too soon

Didnt test it enough, the above code also replaces the first sprite of the bridges with the Menu sprite

This should work:

Code: Select all

  229 * 9	 0D 00 \D= \DR FE FF 08 01 00
  230 * 5	 06 00 02 03 FF
  231 * 5	 0A 01 01 00 00
//Bridge Icon
  232 modular_wider_bridges/gfx/gui_icons.png  8bpp  340     2    43   20   0    0 normal //bridge icon 00
  233 * 5	 06 00 02 06 FF
//!!Error (141): ID 0D out of valid range (00..0C).
//!!Fatal Error (47): Offset 5: Invalid property 14.

That will indeed be very handy (and will give other bridge-designers some more freedom to add unique looking bridges), thnx!

For now I hope that this will be enough:

Showing off a bit

For my personal games I have modified this GRF to show highway graphics with an extra (fake) lane.
Combined with a (completely useless, except for visual pleasure) roadtype that looks like the centre-piece of the Dutch Roadfurniture, you can get these kind of bridges:

In summer:

: Screenie06.png (132.24 KiB) Viewed 10000 times

(By using the roadtype I can get the centre of the bridge to appear snow-aware)

Showing what you can do if you place objects next to the middle piece (with just a road, nothing else) to make custom bridges:

Some time ago, I already included that particular feature into m4nfo, but was lazy in documenting it.

Example for bridge pillars on station tiles:

Code: Select all

grfinit(
    ...
    feature_test(
        feature(STAT_PILLARS) // test if feature 'define pillars on stations' is available
        feature_version(1)
    )
    feature_test(
        feature(PROP_MAPPING) // test if feature 'property mapping' is available
        feature_version(1)
    )
    feature_propertymapping(
        mapping(STAT_PILLARS, {bridge_pillars}) // link user-supplied function 'bridge_pillars' with next available station property
        fallback(0)
    )
)

...

property_mapping({bridge_pillars}) // set up user-supplied function

...

skipif(1, FEATURE, !=, STAT_PILLARS) // don't use it for station IDs 7 .. 9 if feature is not available
setproperties(7 .. 9,
    bridge_pillars(3,3,3,3)
)

OTOH, bridge set developers seem to be notoriously unwilling to give up their inherited nfo copy/paste style. So ...

regards
Michael

Hope you don't mind, but I went ahead and did a bit of editing of your NFO.

I've added the flags to stop AIs/GSs and towns from building these bridges.
I also added the pillar flags for completeness' sake.
I moved whether to use bridge slots 10-12 or 13-15 to a parameter, such that the GRF works both with trunk and JGRPP.
