I've always kinda wanted to have a god at creating my own version of the Starting Ratings GRF viewtopic.php?p=1183003#p1183003 as I thought that since it doesn't deal with graphics development, but instead, depends entirely on scripts, I'd have an easier time with creating my first GRF, But I am having trouble getting started.
So I did a quick search around the internet and discovered that NML was a good program to code in, but I need a program to compress the files into a Game Resource File.
So first, I looked around for the tools that are used for OTTD development https://wiki.openttd.org/NewGRF_development_tools and despite how many tools are there, there are only 2 or 3 tools which are actually used for GRF development, which are the following:
- GRF Wizard - which seems to be a tool that handles with purely the graphics side of things (Sprites and all that.), it links in with GRF codec which, in itself, does very much the same thing, just with Command Prompt.
- NML - Which seems to be a command prompt program to compile scripts written in NML written by an external editor (eg: notepad or notepad++).
- m4nfo - Another NML editor which seems to need its own Operating System.
