Every Script has its own Script Table. It returns a Lua table that can be used for two things:
- Storing variables for the Script
- Callback / Event Handlers
Using the Event Handlers is also the only way to properly unregister event listeners from the Game's event system. We strongly recommend not using global variables or functions in Scripts, since these won't be properly garbage collected and could cause conflicts with other Scripts.
For Mafia Definitive Edition, use ScriptHook.CurrentScript() instead.
Script() in Action
This example illustrates how you can avoid using global variables & functions and how the Script() function can be used instead. Syntax:
Script()
main.lua
local script = Script()
script.my_variable = 1234
function script:PrintMyVariable()
print(self.my_variable)
end
include("test.lua")
test.lua
-- Prints 1234 twice
print(Script().my_variable)
print(Script():PrintMyVariable())
Event Handlers
Check out this guide about Event Handling.
