NML/NFO to GRF Related problem......

[YNM]

I already tried for a twelve times to do that....

Heck, the same and the same and the same again.....

"nmlc: error: Error: only a single nml file can be read per run"

That's what the (Heck!) Command Prompt always says.

(Sorry too for always asking about this, I just want to learn.... )

[planetmaker]

Sadly you fail to actually document for us what you try, so all we can do is (again) only speculate.

Don't use filenames with spaces.

Also when it may seem obvious to you, please *always* when reporting issues:
a) State your goal (kinda clear here)
b) describe what you did *exactly* (not clear at all. "I followed the tutorial" is never a description. Document exactly what you do.
c) report what output you got *exactly* (is it a full quote you give us here?)
d) tell what you expected instead (kinda clear)

for command line programmes this includes quoting verbatim of what you typed
In any case exactly quote what output you got (never paraphrase it or 'quote' approximately). Use a screenshot, if you cannot copy&paste.

[YNM]

Well, the code at the page before this is the full code / quote, purely.
Now it's already changed by fixing the typos, as well as following your assistance.
(I can't post the code now, I no longer on computer)

At last, the only problem saw by me is the graphics pallete... maybe an artist can solve it.

[FooBar]

In this case I suspect a problem with the command you put in the command prompt window. It would help if you could post that; this is what planetmaker meant with "exactly".

It's easier if you copy/paste the command instead of a printscreen. In that case I can easily provide you with a correct one if it doesn't work. In case of the printscreen, I really cannot be bothered to type that over

[YNM]

Just see the code a page back, the spritesets directory "gfx/BB series sprite" but in my latest version, I removed the "gfx/" because I think it should be used when the sprite is stored in gfx file...

later then, it says that nmlc can't decide the palette, even the ANY palette....

may you see the template to teach me how to exactly use it..... or suggesting for the draws....

btw, I will try later with filename without space but underscore... (Its nearing 12 am here, good night...)

[FooBar]

Code: Select all

"gfx/BB series sprite"

In that bit, you appear to be missing the file extension. Assuming your graphic files have one of course! Windows hides those by default, just so you know. But even then you have to supply them in your nml file. And while you're at it, indeed get rid of the spaces.

About "gfx" you're right, you only need that if your sprites are in a gfx folder (relative to the nml file).

As for the palette, there's no "any" palette. It's either the dos palette or the windows palette. Use the dos one if you're not sure. Here's how to apply it to your graphics file: http://www.tt-wiki.net/wiki/Save_paletted_image_files

[YNM]

The ANY palette was described in nmlc option -p or --palette=

Well, for the paletted images itself, does anyone have a palette for MS Paint ? I was have the Photoshop Cs 3, but I lost the cd

Or, is GIMP is freeware ? If not, can't talk anymore... someone has to convert the graphics in Photoshop or GIMP for me

addition : the current full code :

... the command I usually use to run it :

Code: Select all

D:\New folder>nmlc -c --grf ITP_try.grf ITP_try.nml

and the latest graphic (no changes, just to make you easier to see it)

[Eddi]

yes, GIMP is free. get it on www.gimp.org

[FooBar]

The ANY palette was described in nmlc option -p or --palette=

Oh that. Well, that means that NML will determine the palette for the grf for you. It'll use the Windows palette if all your graphics files are in the Windows palette, or the DOS one in all other cases. Your graphics files still need to be in one of those two palettes though.

Well, for the paletted images itself, does anyone have a palette for MS Paint ?

Paint doesn't understand palettes, so no
It's fine to draw in paint, but you need an additional program to apply the palette.

the command I usually use to run it

I would avoid spaces in any folder or file name. But apart from that the command is fine.

[YNM]

I already paletted it, but nmlc says "Invalid palette; does not contain 256 entries" ,

How is the way straight out from this ?

EDIT : sorry, this is the paletted graphics (done it as in the palette tutorial) :

[FooBar]

It's certainly paletted, but the palette applied to that image is certainly not one of the two TTD palettes.

Are you sure you did this step?

Make sure to uncheck Remove unused colors from colormap.

[YNM]

At last....

Yes !!

It is finished !!!

But...

Heck, it says an internal error occured :

Code: Select all

Error: "The _imaging c module is not installed".

Does anyone know what is the cause of this ?

[FooBar]

Either _imaging.pyd is missing, or the build of the nml program is broken.

The latest nml nightly (r1886) works here on Windows, so if you have any other version you can give that a try.

[YNM]

Does the imaging.pyd and/or other files (eg. haslib.pyd, etc.)that can be extracted from nml download .rar have to be in the same folder?

If yes, then thats my fault... and thats mean my grf is completed.

[FooBar]

Yes, either next to nmlc.exe or somewhere in the search path of the operating system, as explained in the NML tutorial

[YNM]

Thank you FooBar, planetmaker, and Eddi !
Now the grf is complete !

It's just the graphics still not placed right... I will try to do that myself.

And a simple last question : for multi-object, eg. a combination of engines and carriages, how to put them on ?
Especially with those brackets ; I don't want to make them wrong.
this brackets { } I mean.

[FooBar]

As in a multiple unit or something? Just follow the NML tutorial; it explains that. If you don't get something from the tutorial, feel free to ask though!

In general you need the articulated vehicle callback to make the vehicle ... articulated.
And a switch block to decide the graphics for each part depending on the position_in_vehid_chain variable.

[YNM]

Oh, sorry, I use the wrong words...

I mean, If I want to make eg. complex trainset with several engines, several coaches, and several car, how to put the template and the vehicle definition ?

For articulated, how to make a vehicle, but still able to carry wagons in the middle of them (push - pull engine, for short) ?

[Eddi]

each vehicle goes into one "item {}" block. just line them up after each other.

[YNM]

Firstly, sorry for restarting the topic...

Well, I have decided to code again... This time, the templates are just right. Only offset need to be repaired.

Starting the more-than-one-vehicle GRF, I choose to copy the first block (Including templates and items) and modify them a little bit (Eg. x,y coordinate, location, item name, strings, etc....)

The problem is that nmlc says that the code isn't UTF-8 coded, through I already blocked all the code and convert them to UTF-8 in Notepad ++ :

UTF-8 Problem.png (43.07 KiB) Viewed 1800 times

then nmlc says this :

UTF-8 nmlc screen.png (19.85 KiB) Viewed 4280 times

At last, here's the full code to be checked if there any fault inside.

ITP_try.nml

(Too long if I copied all of them)

Any comments, help and suggestion will be appreciated.
