Update 3
Launch Game Autorun Files Version 1.02
Added a 'Launch Game' button on the main form of cheat engine. This is useful when opening the table after opening cheat engine, or when game has been closed or crashed and you want to launch it again.
Update 2
Launch Game Autorun Files Version 1.01
I've added a clever trick to make the script compatible with tables that overwrite the onOpenProcess() function. Also fixed a typo that doesn't change any functionality. Basically, when the main form loads, the script stores the old onOpenProcess in another variable, overwrites the onOpenProcess with it's own, then changes it back when it's done.
Update 1
Launch Game Autorun Files Version 1.0
I've rewritten the script to directly read and write necessary data in the .ct file instead of using extra memory records that pollute the table. There's also many new features:
- Launch Game
- Launch With Advanced Options (parameters, debug and BreakOnEntry)
- Ask whether to launch or not when an instance already exists. If not it only attaches to the process. If yes it doesn't attach as there's more than 1 process with same name.
- Advanced Options are saved between sessions so long as the cheat table is also saved.
The code:

old post
Since I'm too lazy to manually click to open cheat engine, launch the game, minimize the game, attach cheat engine to process, activate cheats, go back to game, I've decided to automate all that. After wasting time messing around with reg query to get game's exe file path from registry, I've realized I was severely over complicating stuff. Thus I came up with a simple script that should work in every game, allowing you to automatically launch the game when you open the cheat table. My knowledge of Lua is still very superficial, and I'm learning as I go, thus it's likely there are many areas where the script could be improved.
A quick explanation of what happens:
1) The first time the table is opened, nothing happens until the user attaches cheat engine to the game's process.
2) When a process is attached, onOpenProcess is executed, saving the game's file path and process name in the addresses of new memory records.
3) When the cheat table is opened again, it prompts the user if they want to launch the game.
4) Using the saved file's path and process name, and createProcess of course, cheat engine launches the game and attaches to the process.
5) After that you can create a favorite group of scripts that are automatically enabled, meaning you never have to minimize the game.Code: Select all
local path_record = AddressList.getMemoryRecordByDescription('GAME PATH') local name_record = AddressList.getMemoryRecordByDescription('PROCESS NAME') local parent = AddressList.getMemoryRecordByDescription('START') function launch_game(path, process_name) if not path then return 2 end createProcess(path) getMainForm().WindowState = 'wsMinimized' sleep(1000) local pid = getProcessIDFromProcessName(process_name) if pid then openProcess(pid) else return 1 end return 0 end local function get_path(pid) local modules = enumModules(pid) if modules and #modules > 0 then return modules[1].PathToFile end return nil end function onOpenProcess(processId) if not parent then parent = AddressList.createMemoryRecord() parent.Description = 'START' parent.IsGroupHeader = true parent.Options = '[moHideChildren]' end if not path_record then path_record = AddressList.createMemoryRecord() path_record.Description = 'GAME PATH' path_record.appendToEntry(parent) end path_record.Address = get_path(processId) if not name_record then name_record = AddressList.createMemoryRecord() name_record.Description = 'PROCESS NAME' name_record.appendToEntry(parent) end name_record.Address = process end if path_record and name_record then local response = messageDialog("Launch Game?", mtConfirmation, mbYes, mbNo) if response == mrYes then local game_path = path_record.Address local game_process = name_record.Address if launch_game(game_path, game_process) ~= 0 then showMessage('Failed to launch game') end end end
