Message systems are a somewhat common design pattern.

In TPP messages are sent from the engine to the lua vm to communicate events or other information.

There is no direct equivalent from lua to engine, instead direct engine module function calls are used or game object commands.

For the TPP Lua modules subscribe to whatever message it’s interested with a function to be called.

function this.Messages()
    return Tpp.StrCode32Table{
        [message Class]={
            {msg='msgName', func=this.functionName(params)}
        }
    }
}

The messages pass through TppMain.OnMessage which dispatches to the subscribed modules.

A breakdown of some messages by message class with parameter information can be found in the Infinite Heavens MGS_TPP\mod\modules\IHLookup.lua messageSignatures table.
