GRF encoder tool: GRFMaker [under development]

[Bob_Mackenzie]

I have an articulated vehicle

However I'm now struggling with how to get the graphics to change with a refit - help please

Cheers

I was following the user guide while making my first train loco, and every time I set the image to "fstloco.BMP" in the vehicle sprite block, an error comes up:

RANGE CHECK ERROR.

How do I solve it?

[AndersI]

Make sure that "fstloco.BMP" is in 256 colors, using the correct palette. Also make sure that the sprites all start at the same pixel line, that you have a small white margin around all the sprites (and that the image isn't exactly 256 pixels wide?).

[kcjonesrr]

What do you mean? Here's the sprites.

[Bob_Mackenzie]

They look too close together to me - there must be at least 4 pixels between each element, and 4 white pixels between the elements and the outside edge of the picture

[AndersI]

Actually, that's not true. There are two things that are important, though:

- make sure the image is in 256 colors, preferably a .PCX
- make sure there are at least four empty lines *under* the sprites (GRFMaker uses this space to encode xrel/yrel in the image)

Doing those two changes on your image makes it work for me in GRFMaker 3.04B_r216

Thanks. When I tried to make the .grf file, it says this:

ERROR: Invalid filename.

How come?

Thanks. When I tried to make the .grf file, it says this:

ERROR: Invalid filename.

How come?

The directory your trying to compile the grf to does not contain a "newgrf" folder (it must be named newgrf)

[kcjonesrr]

You mean set the game's path to a newgrf folder?

[NekoMaster]

You mean set the game's path to a newgrf folder?

Say you set it to "C:\Program Files\OpenTTD" then the folder the path points to must contain a folder called newgrf

[kcjonesrr]

Thanks. Now I've made my first grf file, you can find it in the Graphics Development forum.
BTW, if I'm making multiple locos, do I repeat the process as shown in the tutorial but give them different IDs?

[Bob_Mackenzie]

Only the ID blocks need new ID;s the graphics blocks (G) can re-use ID's

[Bob_Mackenzie]

I'm using v4.01 to code helicopters (see the release forum)

The speed certainly isn't in kmh - I've entered a value of 60 to get a game speed of 96mph (edit Ive sussed it - 60 is HEX for 96)

Also the button to change the running costs doesn't work

[EDIT]

It also fails to load rotor sprites and kills the prog with the following error

Unfortunately, it's not much use reporting problems with GRFMaker 4.01, as the open source version is only at 3.04B_r_<something>. I don't know who is programming the 4.01 version, but it seems it is only available on the hungarian tt-forum?

Anyway, we can only find and (possibly) fix problems in the open source branch, not in other versions.

I dunno how do you call that but i want to make different skin for the same wagon depending of the train. Because i'm making train set and i want to do somehing like Temperate trainset GRF witch they change from the color of the train. Its is possible and how it would be. I'm using GRF Maker 4.01

Thanks

It's possible, you have to set these things in vehicle assign block.
If a passenger car attached to this locomotive (red marked), the blue marked graphics ID will be shown in game. Of cours, you need to set a new graphics block with that ID to gt it works.

[Zonta]

By the way is this possible to add more train in the game? I would like to keep all those train who are already existing and i want to add a new Maglev. It is possible to create some ID that don'T exist?.

[colossal404]

No, you have to overwrite an existing vehicle, but use the toyland vehicle IDs.

[Bob_Mackenzie]

Unfortunately, it's not much use reporting problems with GRFMaker 4.01,

I fear you are right - I was wondering if Colossal 404 has contacts?

[colossal404]

Yeah, I have contact with the programmer, so I can report bugs to him.
