Events - Windower/Lua GitHub Wiki

This page describes the process of registering an event to execute, as well as provide a full list of all available events.

An event is in this case simply an in-game event. This can range from logging in, to an incoming tell, to losing or gaining HP during battle. There are various events all of which can be reacted to.

All events are registered with windower.register_event(name, fn), where name is the event to register and fn is the function to execute.

function print_values(new, old)
    print(new, old)
end

windower.register_event('status change', print_values)

This can usually be simplified by just dropping the function into the definition:

windower.register_event('status change', function(new, old)
    print(new, old)
end)

Sometimes (such as in this case) this can be further shortened to the following:

windower.register_event('status change', print)

This will have the same effect since print takes an arbitrary number of arguments, so it will simply print out all arguments the event provides.

The following is a list of all available events, as well as the arguments they provide. Some of them will take return values to modify their content.
