Preface

In the early days of Cyberpunk 2077 modding, we noticed a lack of discipline and proper use of the SDK provided by CET. So we strongly recommend you read this and understand what is expected of you and your mods.

First of all we advise that you do not use keyboard events except in the following cases:

• You need a quick input (for example pressing the key triggers a super power that kills the target)

• Your mod is huge and you need a key to get it up (for example a multiplayer mod)

And here are some examples of when not to bind a key:

• To run a few lines of code that are not time sensitive (upgrading all items to Legendary)

• To open the user interface of your mod (prefer adding a menu to the toolbar)

• To override game inputs

Structure

All mods must be located in bin\x64\plugins\cyber_engine_tweaks\mods\otherwise they will not be loaded. You need to create a directory for your mod, we suggest you name it in snake case for uniformity (see the example below).

In your directory you need to create a file init.lua that will contain your initialization code. This is the only file that will be automatically loaded, it is mandatory that you name it init.luaexactly.

In init.lua you can register for events that will get called automatically, onInit , onShutdown, onUpdate, onDraw, onOverlayOpen, onOverlayClose via the registerForEvent(name, callback) function.

Example

Let's assume we wanted to create mod called Is Player Naked?! that prints every frame if the player is naked or not. We would create a directory called is_player_naked and create an init.lua file in it. You should have the fullpath bin\x64\plugins\cyber_engine_tweaks\mods\is_player_naked\init.lua we can now add the following code in init.lua .

-- You can use this object to store any type of variables.
IsPlayerNaked = { 
    description = "Checks if the player is naked!", 
    Player = nil
}
​
function IsPlayerNaked:new()
​
    registerForEvent("onInit", function() 
        IsPlayerNaked.Player = Game.GetPlayer()    
    end)
​
    registerForEvent("onShutdown", function()
        IsPlayerNaked.Player = nil
    end)
​
    registerForEvent("onUpdate", function(delta)
        print("Is the player naked this frame? " .. tostring(IsPlayerNaked.Player:IsNaked()))
    end)
​
end
​
return IsPlayerNaked:new()
