GRF encoder tool: GRFMaker [under development]

[gl2]

right.. now I need the basic files for TTDLX... Cuz when I start my version, it saids error reading registry.. and I don't even have an .exe files called transport tycoon deluxe.exe or something.. only ttconfig.exe

Hello Darkmast49!

Szappy sad:

The problem is, that GRFM is looking for a dir called 'newgrf' under the TTD directory. You can solve this problem by creating this directory in the openttd dir, then, after creating the grf file, you can move it to the proper openttd dir.
Also please note, that GRFM was not designed for OpenTTD, so not all of the functions in GRFM will work under OTTD.

aah thanks for that! Lets try it out..

EDIT: Same problem.. I think it's the OpenTTD being problem..

[DaleStan]

GRFMaker can generate Open-compatible GRFs, but I strongly encourage you not to try that; Open's newgrf support is documented exactly nowhere, so you'll never quite know whether your code or Open's support is broken.

Ok, gonna try and find a PROPER download of TTDLX and TTDPatch, as now it gives an error reading registry.. But do you now how to solve the problem I have with GRFMaker, error (invalid filename)?

[krtaylor]

If all you have is a registry error, you may be installed OK except for the registry. You can fix it easily with the registry tool, I think it's on the Patch website under tools.

[Patchman]

If you get a registry error, you're trying to run TTD directly instead of the patch. So run the patch instead. The latest versions need no registry entries.

[Samwise]

Thanks for the tips guys

EDIT: Now I have other problems.. TTDLOADW.OVL not found
GAMEGFX.exe: No such file or directory.. Gonna try and find them right now..

EDIT: GAMEGFX.exe found, and it works, TTDLOADW.OVL found as well, but it gives an error of ongeldige segmentlengte? (find a dictionary for dutch cuz I can't translate this to english..

[Patchman]

Most likely the gamegfx.exe is not the TTD/Win gamegfx.exe but some other random file. You have to get the gamegfx.exe that comes with TTD.

[Samwise]

Ok Patchman.. where to download that? (I wish I still had the harddisk of my old pc, it was on there... )

I was trying to figure something out, and the Wiki isn't helping due to the diffrences in terms, but I've been trying to figure out how to set up a livery refit (where you can change the livery by using the Refit window). I have callback 19 on, but after that I'm hopelessely lost. Could one of you please help?

[DaleStan]

In the CB19 section of the action 2 chain, check (byte) variable F2. For each value starting at 00, return the xx of one D0xx text that you want attached to the cargo type. Once you have returned all desired texts, return and FF for all other values of F2.

In the graphics section of the action 2 chain, check variable F2, and return the graphics that correspond to the D0xx text that is returned by callback 19 for the same value of F2.

Hey, would someone please mind giving me an idiot's guide to making steam engines with tenders? I downloaded the guide file but I can't understand it without instructions explaining it. I know it uses some kind of variational graphics, but I can't figure out how you make it attach to the rest of the engine when you buy it. Help would be greatly appreciated!

[krtaylor]

Another budding coder? Great news!

[lws1984]

ERm.... thanks DaleStan, but there appears to not be a CB19 section of an Action 2 chain, nor is there a place for variables in the graphics section.

[Samwise]

At last I have TTDPatch.. but yet another problem.. Which buttons I have to input to change a trains graphic to my creation? And it still gives the problem of invalid filename..

Callback 16

ERm.... thanks DaleStan, but there appears to not be a CB19 section of an Action 2 chain, nor is there a place for variables in the graphics section.

"CB19" is my lazy way of referring to callback 19. Do something like:

Code: Select all

1*0 04 00 9F 02 00 D0 " first livery" 00 " second livery" 00
2*0 01 00 02 08
//sprites for first livery
//sprites for second livery
3*0 02 00 00 01 01 00 00 00 00
4*0 02 00 01 01 01 01 00 01 00
5*0 02 00 02 81 F2 00 FF 01 00 00 00 00 01 00 // Select graphics (first livery if F2==00, second livery else (if F2==01)) 
6*0 02 00 03 81 F2 00 FF 02 00 FF 00 00 01 FF 01 01 FF FF // return texts for CB19 ((D0)00 for F2==00, (D0)01 for F2==01, FF else)
7*0 02 00 04 81 0C 00 FF 01 03 00 19 19 02 00 // Check for CB19
8*0 03 00 01 XX 00 04 00

As I've mentioned, I don't use GRFMaker, but that's the NFO for doing two liveries.
To add a third livery, add a third string to sprite 1, a third set of sprites after sprite 2, a third copy of sprite 3/4, and an additional option to sprites 5 and 6.

Just a suggestion after coding some trams:

Perhaps you should update the "position" window with a road for RV's so that you don't have to approximate on the train tracks.

Szappy, i seem to get an error everytime i try to make a .grf file thorugh GRFMaker, it says 'Invalid filename' whilst trying to create it.

Got any ideas?

[DaleStan]

Note: I coded these to be compatible with the nightlies. They might work with the betas.

I'm probably just anal-retentive, but I'm of the opinion that any GRF released should have version-checking code, and that the specified minimum version should, in fact, be the first version that supports all the features that the GRF uses.

Ofcourse, something that advanced is out of my coding grasp

You use GRFMaker, right? Maybe it's time for a feature request: "Automatic version checking code"?

It'd take a quite a bit of work, but the introduction date of most newgrf features is pretty well documented, IIRC.

Of course, an override would be necessary so people who insert literal NFO could change the minimum version correctly.

Is this project still being worked on?
