Hello,
I just drawed my first building (new hq stage 4).
It's now in png and I want it in my game!
I read somewhere that I have to make a nfo file too but I also don't know how to do that.
Could anyone tell me what I have to do?

It's very complicated, I can tell you that. You can look at http://wiki.ttdpatch.net/tiki-index.php ... phicsSpecs for some info...

Basically, it's a long process, which takes a long time to learn. I'm kind of learning, but the Wiki is the right place to start. I haven't found another tutorial in NFO creating anyway.

Uhhh the basics at max take 1 day, i wouldn't define that as long time..
Not to mention he just wants to replace the HQ building, wich should be very easy..

It depens how good is your english.... Basics is easy to understand, but when you are going on, then the English is going harder imo.(more specific words

)

Yes, you could do with with tools entirely using action A.

For just doing that, using grfdiff and the grd2grf converter are probably the easiest to use.

Isn't it possible to use another system instead of newgrf files?

DaleStan · Post by **DaleStan** » 02 Feb 2006 19:47

You can use grfdiff to create a win32 binary that will modify your ttd grf files.
You can use grfdiff to create a grd file that will tell grfmerge how to modify your ttd grf files.
Somehow, I don't think that those are improvements.

But it's the output from grd2grf is an action A grf. Those should not be able to cause desyncs.

This is what someone told me to do if I want to make my own graphics:
PNG -> PCX
PCX + NFO + Grfcodec -e -> GRF

Well I have a PCX file now and my question is: what to do?
I know I need an NFO File but how do I make one?
I took a look at the wiki page but thats about trains, but how about buildings?

I have these programs:

-Grf wizard 1.9.0.1
-Grdtogrf,
-Grfcodec,
-And Nfo Editor. 1.1.0.6
Are there any programs that I need to have?

It's 5am, I have nothing better to do, so quick and dirty guide to replacing the HQ sprites using an action A.

You won't need anything on that list except grfcodec, and you will also need nforenum.

1) decode trg1r.grf, if you haven't already. Open the pcx file and find the HQ sprites (2603 to 2631).

2) Paste your new HQ sprites into trg1r.pcx, over the existing ones. Hopefully they are the same size - if not, you will have to adjust the sizes and offsets later on. Save the pcx file.

3) Create a new text document. This will be your NFO file. Name it <whatever>.nfo, where <whatever> is what you'll want the grf file to be called.

4) Paste the following into the nfo file:

Code: Select all

// Automatically generated by GRFCODEC. Do not modify!
// (Info version 6)
// Format: spritenum pcxfile xpos ypos compression ysize xsize xrel yrel
    0 * 4	 00 00 00 00

This is the header which all NFO files must have, and your sprite 0.

5) Add the action 8 psuedosprite. eg:

Code: Select all

1 * 1	08 06 55 55 01 01 "My HQ" 00 "By Me" 00

See the action 8 wiki page for exactly how the action 8 works.

6) Add the action A psuedosprite. This will look something like this:

Code: Select all

 1 * 1	 0A 01 1D 2B 0A

where 1D is the number of sprites to replace (29 = 1D in hex), and 2B 0A is the sprite number to start replacing from (2603 = A2B in hex, which with the bytes in little-endian order becomes 2B 0A). If you don't want to replace all the HQ sprites, adjust these numbers so it's replacing the sprites you want to replace.

7) open trg1r.nfo, find the lines for the sprites you have replaced (the sprite numbers are the same as appear in the pcx), and copy and paste them into your nfo file after the action A sprite. If your sprites aren't exactly the same size as the defaults, you'll have to adjust the sizes and offsets at the end of the lines - the format is given in the NFO header. But don't worry about this until you've got the grf file working - you can always go back and adjust later.

Your nfo file should now look something like this:

Code: Select all

// Automatically generated by GRFCODEC. Do not modify!
// (Info version 6)
// Format: spritenum pcxfile xpos ypos compression ysize xsize xrel yrel
    0 * 4	 00 00 00 00
1 * 1	08 06 55 55 01 01 "My HQ" 00 "By Me" 00
1 * 1	 0A 01 1D 2B 0A

 2631 sprites/trg1r.pcx 658 9816 09 31 64 -31 0

8) Save the nfo file and run it through nforenum. This should fix up the sprite numbers and tell you if you've got any errors.

9) if you don't have any errors, encode with grfcodec, and you should have a working grf file.

Good luck, have fun...

thank's ,I'll try

ehm, How do I decode it?

RSpeed tycoonfreak wrote:ehm, How do I decode it?

Using grfcodec.

The readme should contain all the information you need.

RSpeed tycoonfreak · Post by **RSpeed tycoonfreak** » 25 Feb 2006 21:06

It doesn't work.
If I use grf wizard and i select the path to grfcodec I get this: (error1)
And how do I use grfcodec?
Do I have to drag the trg1r.grf on the grf codec.exe?
because if I do that nothing is happening.
Do I have to open the grfcodec.exe?
because if I do that I get a dos screen for about 0,1 sec. and then it's gone.

Please help even if i sound completely stupid now,
because my english is not that good.

Post by **PikkaBird** » 25 Feb 2006 21:20

Okay,

1) create a new shortcut in the directory where you have put grfcodec. In "type the location of the item", type cmd.exe, click next, click finish.

2) right click on the shortcut and select properties. In 'Start in', it will probably have "%windir%". Delete this so the 'Start in' dialogue is empty, click okay.

3) copy trg1r.grf to the directory.

4) run the shortcut. You will get a DOS prompt. Type:

Code: Select all

grfcodec -d trg1r.grf

This will create a SPRITES subdirectory, and put the pcx and nfo files in it. This subdirectory is where you will want to create your new nfo file. You can use this same shortcut for decoding and encoding grf files in the future.

I should warn you, I'm not going to be this helpful for much longer...

RSpeed tycoonfreak · Post by **RSpeed tycoonfreak** » 25 Feb 2006 22:07

Thanks you're very helpful but I think I need youre help one more time:
If i type grfcodec -d trg1r.grf

it says:

grfcodec are not recognised as an internal or external task, programme or batchfile.

(It's maybe not exactly what it suppose to be but I translated it with a translator)

If you or anybody else solve this problem I think i don't need help anymore.

Interesting. I wasn't aware that program was broken too. But it fits; all the rest of the software that person wrote is broken. (grfcodec works just fine from directories containing whitespace; I just checked.)

EDIT: Re-read Pikka's instructions. You forgot a step.

DaleStan · Post by **DaleStan** » 26 Feb 2006 00:40

Actually, there's another option too: You moved the shortcut to a directory other than the one containing grfcodec.

If that's the case, change #2 to "Enter the directory containing grfcodec and the grf files in the 'Start in' dialogue".

would probably work for a normal GRF, but not for OTTDs 34bpp, for a start, the 32bpp base image is, 32 bit, including RGB+Alpha. PCX is only 24bit, RGB only. so, the alpha is already gone out of the windows, and we havn't even looked at the 2bit CC overlay yet.
