I've decided to release a few resources made for the mod by us, to give you some examples how scripting works in Bully MP.
We took some concepts from Multi Theft Auto and nanos Team (GTA-MP authors) for our scripting system.
To begin with, each extension is a resource, which is a collection of files and a meta file which describes how to load them.
Every resource needs to have a server-side boot script, which should contain initialization code, load the other scripts.
You can make client-side scripts too, they work mostly the same way, but there are some differences.
An example is the global object which contains rendering functions for the client, it's only available for client scripts.
Keep in mind, all these things are subject to change, because the scripting API is still under development.
When it will reach it's final stage, we will start documenting everything on our wiki.
Until that, here are some early examples.
