### Add Custom Packet Handler for PlaySound RPC (Lua)

Source: https://github.com/the-fyp/samp.lua/blob/master/README.md

This example shows how to add a custom handler for the PlaySound RPC using SAMP.Events and SAMP.Raknet. It logs sound information and mutes the sound.

```lua
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
```

### Handle SA:MP Chat Messages with SAMP.Events (Lua)

Source: https://github.com/the-fyp/samp.lua/blob/master/README.md

This snippet demonstrates how to use SAMP.Events to intercept outgoing chat messages in SA:MP. It shows how to print the message, modify it before sending, and interrupt the sending process.

```lua
local sampev = require 'samp.events'

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

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

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