Some Requests (Help Needed)

[planetmaker]

Open the command window (dos prompt) and use it there.

I Opened it with Dos Prompt but how do i Use it?

Have a look at the supplied readme. Works wonders.

[RL Conroy]

Assuming your using vista/7

I'm using Windows Vista

4) Type in 'cd C:\Program Files\OpenTTD\' (or wherever grfcodec is on your computer).

I Putted them in a Folder in a Folder on my Desktop so what must i type in?

If they do, check for viruses.

Thanks. I'm Scanning it right now for Viruses

Have a look at the supplied readme. Works wonders.

Strange enough; I don't have a ReadMe!
EDIT: *Note to Myself: The ReadMe from GRFCodec not DOS Prompt!*

Sorry for all the Questions but i'm trying to get as much Info as Possible

[FooBar]

It's easier to shift+rightclick on some empty space in the folder with the grf and grfcodec (this can be the desktop). From there you can open the command prompt in that folder, so there's no need to cd to it. Make sure no file or folder is selected while doing so.
Also assuming Vista/7


Please note that if you decode a grf and change it, you need permission from the author(s) of the original grf before you can release your derivative. For personal use it's generally fine to decode an change something, but you shouldn't share such changes without permission. Several grfs out here have a license that permits changes, mostly under the condition that you release the source of your changes under the same (free) license. But again for personal use and learning how NFO works it's fine to decode a grf to see what's in it.

No Viruses Found

I Exactly did what you say but what now?

[Chris]

Running everything as an administrator is not a good idea. These tools should not need administrative priviliges. If they do, check for viruses.

I always find with the cmd that when I run it as an administrator, it comes up as C:\Windows\system32>, whereas if I don't it comes up as C:\Users\Christopher>. My grfCodec isn't in my users file.

[FooBar]

I Exactly did what you say but what now?

You didn't do exactly what the grfcodec instructions say

To decode a grf:

Code: Select all

grfcodec -d -p 2 filename.grf

If you decode a grf with the DOS palette you can leave the -p 2 part out. That part makes a grf with the Windows palette decode correctly.

[RL Conroy]

So if i Understand it Correctly...
I must Rename the GRF?

You didn't do exactly what the grfcodec instructions say

Sorry about that. It is New for me

grfcodec -d trg1.grf
Convert trg1.grf into a PCX file which you will find in the SPRITES folder

From http://www.ttdpatch.net/grfcodec/

[lawton27]

So if i Understand it Correctly...
I must Rename the GRF?

No, you can just use the name which the GRF already has, if it's easier to rename it to be something like decompile.grf you can but there's no reason to.

[RL Conroy]

Oh Sorry... I have the Tutorial here now
I overlooked it...
I'm Understanding it Now!

I'm going to Sleep now for my Work but Thanks A LOT with Helping me.
Tomorrow i will Try to Decode a GRF File at home and then i will tell how it goes.
And everyone who reads this... Good Night
Conroy Out.

[Ammler]

Yes, use GRF codec, here: http://www.ttdpatch.net/grfcodec/

looks outdated, try http://dev.openttdcoop.org/projects/grfcodec

[RL Conroy]

Can someone help me?

At First when i Typed in the Code

Code: Select all

grfcodec -d filename.grf

it appears Strange at GIMP! What supposed to be Black is now PINK! (I hate PINK! )

I Removed the map "sprites" because of the PINK Problem.

When i Retried it with the Same Code it says at DOS Prompt "Permission Denied"!

And when i Typed in this code

Code: Select all

grfcodec -d -p 2 filename.grf

Foobar gaves me it says at DOS Prompt "Permission Denied" again!
Help me please

[FooBar]

Close the opened file in GIMP before you run grfcodec. It wants to write the pcx file, but it isn't allowed to do so due to the file being open. At least that's my bet what's wrong.

The pink colours are indeed fixed by adding "-p 2".

[RL Conroy]

Close the opened file in GIMP before you run grfcodec.

*Facepalm* Thanks for that.

The pink colours are indeed fixed by adding "-p 2".

Yes it works! Thanks i can go to Work now with it but first i'm going to Eat.
When i'm back i will tell how it goes.

EDIT4: I had no Time when i was done with Eating so i will tell it Tomorrow.
I also had 4 Questions:
Queston 1: If i'm gonna Replace a Signal at GIMP must it be the Same in the Top-Left Corner or...
How do i Explain it...

Question 2: Can i also Edit a GRF that is being Used in OpenTTD?
Because i Spotted in some GRF's some Mistakes...

Question 3: Can i also Create a GRF that Replaces only PBS Signals, Block Signals, or Presignals?

Question 4: Can i Recreate a GRF so that the GRF In-Game is called Different than the Original GRF Name?

[Froix]

Yes you can create and edit NewGRFs to replace just about any graphics in the game. Be wary and respectful of licenses though if you intend to release your NewGRFS.

Question 2: Can i also Edit a GRF that is being Used in OpenTTD?
Because i Spotted in some GRF's some Mistakes...

Yes you can but the best course of action for this is to inform the author at the NewGRF's development thread or release thread.

[lawton27]

Question 4: Can i Recreate a GRF so that the GRF In-Game is called Different than the Original GRF Name?

Yes when you decompile it you should be able to see the name in clear text, of course you can't release someone else's grf just edited so the only use of that might be to add that its your version and not for release so you don't forget.

ad 1)You can freely align and place it. But you have to tell the dimensions and offsets
ad 2)Sure. Somehow they have to be gotten into place... but you cannot edit them ingame. It always involves editing, compiling the grf and then re-loading the game, better re-starting
ad 3)Of course. But as opposed to many other features (vehicles, industries...) you cannot alter how signals work. Only how they look
ad 4)Sure. And please do so.

Have a look at http://wiki.ttdpatch.net/tiki-index.php ... phicsSpecs and look through how other grfs look like, e.g. those found at http://dev.openttdcoop.org/projects

[RL Conroy]

ad 1)You can freely align and place it. But you have to tell the dimensions and offsets

I can Edit the Size of the Signals so long it stays in the Corner.
I mean like this (Look at Attachment). I don't wanna have an Misalignment in my GRF!

ad 2)Sure. Somehow they have to be gotten into place... but you cannot edit them ingame. It always involves editing, compiling the grf and then re-loading the game, better re-starting

When i do that (I don't wanna Try it out) will OpenTTD Crash then?

ad 3)Of course. But as opposed to many other features (vehicles, industries...) you cannot alter how signals work. Only how they look

I only want to Change the Look of the Signals. I can't Reprogram Signals anyway.

ad 4)Sure. And please do so.

Can i do that with GRFCodec?

Don't look at the Signals itself (It is an Mock-Up) but to the Corners of it!

[lawton27]

Yes when you decompile it you should be able to see the name in clear text, of course you can't release someone else's grf just edited so the only use of that might be to add that its your version and not for release so you don't forget.

No you still need to specify the dimensions but in uncomented NFO generated from GRFcodec and to a novice with NFO it would prove tricky, best bet is to keep your dimensions the same.

[RL Conroy]

Oh that's too bad. Thanks for that.

Let me guess... It's in the NFO
But how to open and Edit it?

[Gremnon]

On Windows: With notepad, or with the free download of Notepad++
On Linux: gedit, or any other text editor.

.nfo files are just plain text files.
