omprs

omprs is a tool to develop open.mp gamemodes in Rust.

Structure

Writing my first gamemode in Rust

1. Download the omprs component from here

2. Place the Rust.dll or Rust.so component in components folder

3. Create a new rust project cargo new mygm --lib

4. Add omp to dependecies cargo add omp

5. Add this to your Cargo.toml

   [lib]
   crate-type = ["cdylib"]
   

6. Write a basic code like this

   use omp::{events::Events, main, register, types::colour::Colour};
   
   struct MyGM;
   
   impl Events for MyGM {
       fn on_player_connect(&mut self, player: omp::players::Player) {
           player.send_client_message(Colour::from_rgba(0xFFFFFFFF), "Welcome to my server!");
       }
   }
   
   #[main]
   pub fn game_main() {
       register!(MyGM);
   }
   

7. Build the gamemode

   cargo +stable-i686 build

8. Put the compile mygm.dll or mygm.so to gamemodes folder

9. Goto config.json add following to it

   "rust":{
       "gamemode":"mygm"
   }
   

10. Run your server

lib.rs:

codgen crate that gives proc macros to generate exported functions and FFI related code automatically
