SAMP.Lua

SAMP.Lua is a lua library for MoonLoader that adds some features to make SA:MP modding simpler.

Currently this library is work in progress. At this moment the only implemented module is SAMP.Events.

Installation

Copy the entire folder samp into the moonloader/lib/ directory.

SAMP.Events

Gives ability to handle SA:MP incoming and outcoming low-level network packets by very easy way.

Usage

local sampev = require 'samp.events'

-- intercept outgoing chat messages
function sampev.onSendChat(msg)
  print('You said: ' .. msg)
end

You can rewrite data. Just return all arguments in the right order within a table.

function sampev.onSendChat(msg)
  return {'I said: ' .. msg}
end

You can also interrupt processing any packets by returning false.

function sampev.onSetPlayerPos(position)
  -- prevent server from changing player's position
  return false
end

Adding your own packet handler

local sampev = require 'samp.events'
local raknet = require 'samp.raknet'
sampev.INTERFACE.INCOMING_RPCS[raknet.RPC.PLAYSOUND] = {'onPlaySound', {soundId = 'int32'}, {coordinates = 'vector3d'}}

function sampev.onPlaySound(sound, coords)
  -- add log message
  print(string.format('Sound %d at coords %0.2f, %0.2f, %0.2f', sound, coords.x, coords.y, coords.z))
  -- and mute sound
  return false
end

The same way you can add your own types for more complex packet structures. See source code for more information and examples.
