NML - a Newgrf Meta Language

[Yexo]

That is not possible because as planetmaker said the correct id depends on the current climate and/or loaded industry newgrf. Slot 0x0A for example can be Valuables/Gold/Diamonds, Plastic or Milk.

Well at any rate, it worked. And I'm learning a little more each day now.

Thanks to Ammler there is now a windows binary being build every night. You can download it (along with a .tar.gz of the source) here: http://bundles.openttdcoop.org/nml/nightlies/LATEST/

Is this being built with py2exe or something better?

we are using cxfreeze with wine


Did actually someone test this already, I got an error with images: http://dev.openttdcoop.org/issues/2351#note-7

would be nice to get feedback, if nmlc.exe is actually working

Edit: nmlc.exe doesn't support pcx images..

Have installed windows binary and python27.

So do i use python shell to write file or notepad.

[planetmaker]

You use a (plain) text editor of your choice to write nml files. They should be utf-8 encoded.

Have test file see below

Have you tried to do what the error itself suggests?

[Nickel_Plate]

There is no Lang dir in either python or windows binary so is this something i have to create,
if so were should it be, or should it have been installed with python or windows binary.

I'm trying to make a railtype GRF, and I would like to use the default monorail track graphics. This is what I have so far - the track works properly, the catenary is shown, but the track itself shows up as the normal rail.

Code: Select all

item(FEAT_RAILTYPES) {
    property {
        label:                      "VACT";
        name:                       string(STR_VAC_RAIL);
        menu_text:                  string(STR_VAC_RAIL);
        build_window_caption:       string(STR_BUILD_CAPTION);
        autoreplace_text:           string(STR_AUTOREPLACE);
        new_engine_text:            string(STR_NEW_ENGINE);
        compatible_railtype_list:    ["VACT"];          
//      powered_railtype_list:      ["VACT"];                 
        railtype_flags:             bitmask(RAILTYPE_FLAG_CATENARY, RAILTYPE_FLAG_NO_LEVEL_CROSSING);
        curve_speed_multiplier:     10;
        station_graphics:           RAILTYPE_STATION_MONORAIL;          
        construction_cost:          256;                               
        speed_limit:                0 km/h;
        acceleration_model:         ACC_MODEL_MAGLEV;                   
    }
    graphics {
	CATENARY_WIRE:   wire_group_top;
	CATENARY_PYLONS: pylons_group_top;
    }
}

Thanks,

I'm afraid that you'll really have to provide the graphics for the tracks yourself. You need to provide graphics for all those elements which are indicated by a * in the available graphics block list on http://hg.openttdcoop.org/nml/raw-file/ ... types.html - thus underlay, overlay, tunnels and level crossings; it is not possible to reference the base set sprites for this purpose, those sprite types simply don't exist there.

That said, I'd highly welcome if someone did the actual work to convert the existing tracks (also) into a railtype; it'll mean to probably do a bit colour-select cut and paste of the existing tracks sprites - which is certainly feasible; but if you want the existing monorail as railtype there's little way around that. But as OpenGFX' sprites are under GPL license you could go right ahead with this task provided you're ready to also release your grf under GPL (i.e. attribution and publish the nml, pngs and lng files with each release)

Cheers,

Okay, thanks for that I release everything I make as GPL anyway.

Hi there I'm having problems setting up my nml compiler, I'm running windows 7 64 bit with python 2.7.1, I followed the instructions specified in the documentation, when I run --version I get the flowing response:

nmlVersion.png (63.13 KiB) Viewed 2407 times

However when I attempt to use the following batch file to compile the vacTrain set as a test:

Code: Select all

@Echo off

nmlc.exe --nfo vactrain.nfo --grf vactrain.grf vactrain.nml

pause

ECHO Done!

I get this error:

nmlc error.png (112.79 KiB) Viewed 2407 times

Thanks for any help you can offer,

It will be nice, if you could attach all the files which make up the grf (nml, graphics and language files with their respecive folders), you found a bug in NML. Please try also a more recent version, e.g. the nightly one is found here: http://bundles.openttdcoop.org/nml/nightlies/LATEST/ (you want the windows zip). I'm not sure, maybe it's fixed there, your version of NML is quite old (more than two months).

One guess is that it's a hickup with (missing or wrong) capitalization of file names of one of the graphics files you include.

You also have unreferenced code sections, that's what the first two lines with the warnings are about.

[lawton27]

I don't know why I'm getting this problem I'm using the vacTrain newGrf source as a test, so you can download that from the first post in this thread: http://www.tt-forums.net/viewtopic.php?f=67&t=53743

Using the latest nightly I get the same error except it states the nml version as unknown and by re downloading the source I managed to get rid of the first 2 errors, I must have accidentally changed something there...

Thanks,

Lawton27

No, that was because ou had an old version of th vactrain source That error was fixed.

Hm, I can't reproduce that with NML r1301 or r1307. When I use the vactrain.nml I do get a

Code: Select all

nmlc: Image file "vactrain/sprites/local1.pcx": File doesn't exist

which is solved when I replace all "vactrain/" by nothing and then it compiles for me without error.

What do you mean with "it states the nml version as unknown"?

[Ammler]

be also aware that nmlc.exe doesn't work with pcx
