GUI Sprites (00)

This was literally the first part of the spec for railtype graphics

(Contrary to what the NML spec claims, this is not a callback, it's a "cargo" ID)

Hah, problem solved - my track sprite is displayed, but has same gray color as menu background...

Hello, I'm trying to get compile this nightly version of NMLC in order to compile an industry that has more than 3 input and 2 output cargo types.
I followed the instructions on the github repo about installation successfully, but when I attempt to run nmlc from any folder in my computer I get the error at the bottom (I included the other commands to show that I did just install PIL and PLY is installed too).

[+] Spoiler

Anybody able to help me out on this? Thanks.

looks like some version incompatibility to me...

What is wrong with my pybuild.bat?!

EDIT: NML files must be coded in ANSI to work, apparently.

no, but you can't mix it.

I didn't mix it. Nothing worked until I converted to ANSI.

Please help, Nmlc.exe is not opening at all.

Please help, Nmlc.exe is not opening at all.

Yup. Just as intended.

That is to say, you use its functions through a command prompt window.

[SomeIndianGuy]

What should I write?

Code: Select all

pip 3 install nml

?

No, reread https://www.tt-wiki.net/wiki/NMLTutorial/Installation.
You add it to your environment variables so you can use it over the command line.

All I did was alter tracks.png in GIMP, and now the NewGRF won't compile unless I exclude tramway.pnml

Help? Thanks in advance.

Have you tried compiling without changing the image first? If that works, you know that you changing the image is the cause of the problem. If compiling the unaltered version also fails, you know the problem is not in you changing the image, but in something else.

Did you check that the file in the error message actually exists? (exactly as printed)

For what it is worth, did you try using a path that has no spaces in it like "Recycled Infrastructure Set" has?

For some reason, I got up yesterday morning, attempted the compile, and everything worked. I have no clue what I did right.

How to encode pnml in graphics grf?

[planetmaker]

How to encode pnml in graphics grf?

Usually pnml files are a part of a project which comes with a makefile. This makefile calls the gcc pre-processor to create an nml file from several pnml files. The resulting nml file is then fed to nmlc in order to compile a newgrf from it.

This process is used to allow splitting the code of a NewGRF conveniently into several source files to allow better navigation through the source.
