Is there an easy and reliable way to find messages for third-party mods and the bytes you can send with them?

You can get the names of the messages with "meta game".

For any that don't match the sdk/other games, you would have to use one of trial and error, hooking/reversing, or disassembling the binary.

Thanks a lot, that's awesome. What about the bytes you send with them? Just trial and error on that?

Yhep.
Here's a good snippet for it, it prints the buffer in both bytes and chars.
Can't remember who wrote it. Was in some topic discussing the very same.

PHP Code:

decl String:strRest[256]="";
    decl String:strRestc[256]="";
    decl String:strUserMessageName[256]="";
    GetUserMessageName(msg_id, strUserMessageName, sizeof(strUserMessageName));
    new curbyte;
    while(BfGetNumBytesLeft(hBitBuffer))
    {
        curbyte = BfReadByte(hBitBuffer);
        Format(strRest, sizeof(strRest), "%s%d", strRest, curbyte);
        Format(strRestc, sizeof(strRestc), "%s%c", strRestc, curbyte);
    }
    PrintToChatAll("%s: %s ", strUserMessageName, strRest);
    PrintToChatAll("%s: %s ", strUserMessageName, strRestc);

Where is hBitBuffer declared in that snippet?

Nevermind. x_x

[bl4nk]

hBitBuffer is just the handle to the user message.

What bl4nk said.
You hook the usermessage you want to read and use the above snippet.

So if you want to hook XboxRumble, it'd look like this:

PHP Code:

public OnPluginStart()
{
    HookUserMessage(GetUserMessageId("XBoxRumble"), UM_Hook, false);    // Send a rumble to XBox controller
}

public Action:UM_Hook(UserMsg:msg_id, Handle:hBitBuffer, const players[], playersNum, bool:reliable, bool:init)
{
    decl String:strRest[256]="";
    decl String:strRestc[256]="";
    decl String:strUserMessageName[256]="";
    GetUserMessageName(msg_id, strUserMessageName, sizeof(strUserMessageName));
    new curbyte;
    while(BfGetNumBytesLeft(hBitBuffer))
    {
        curbyte = BfReadByte(hBitBuffer);
        Format(strRest, sizeof(strRest), "%s%d", strRest, curbyte);
        Format(strRestc, sizeof(strRestc), "%s%c", strRestc, curbyte);
    }
    PrintToChatAll("%s: %s ", strUserMessageName, strRest);
    PrintToChatAll("%s: %s ", strUserMessageName, strRestc);
    return Plugin_Continue;
}
