Object Lifecycle

Things in-game can change at anytime. All UObjects exposed to lua are all weak references. This means that it's up to you to manage the lifecycle of all objects you use. For example:

Lets say you store your own player controller in a variable and you access it each frame:

local storage = nil

function onInitialize()
    storage = CONTROLLER;
end

function onRender()
    local pawn = storage:K2_GetPawn()
end

If you loaded this script at the main menu, then joined a game, storage will become invalid as your controller at the main menu has been destroyed. As a result, calling functions on it will not work and may cause your client to crash.
