Create a talking bot for video game

I need a pretty basic bot that will talk in a video game based on a few factors such as dying in the game, someone else dying in the game, or randomly saying something every x amount of minutes. I have a full script of exactly what needs to be done. It will need to be created in LUA ([login to view URL]) because the injection tool for the game I use works off this, so you are creating a script in LUA for the program [login to view URL]
