Cheat Engine comes with an extensive set of Lua functions you can use inside cheat tables, trainers and standalone scripts.


Functions

Cheat table

These functions help manage the cheat table.


Scanning

These functions control Cheat Engine's scanning.


Process


Threads

  • getCPUCount: Returns the number of CPU's
  • getThreadlist: Fills a List object with the threadlist of the currently opened process
  • inMainThread: Returns true if the current code is running inside the main thread (6.4+)
  • synchronize: Calls the given function from the main thread. Returns the return value of the given function
  • queue: Calls the given function from the main thread. Does not wait for the result
  • checkSynchronize: Call this from an infinite loop in the main thread when using threading and synchronize calls


Addresses

These functions help convert between memory addresses and symbols/CEAddressStrings.


Memory


These functions read/write memory from the opened process.

Reading
  • readBytes: Returns the bytes at the given address. If ReturnAsTable is true it will return a table instead of multiple bytes
  • readSmallInteger: Reads a 16-bit integer from the specified address.
  • readInteger: Reads a 32-bit integer from the specified address.
  • readQword: Reads a 64-bit integer from the specified address.
  • readPointer: In a 64-bit target this equals readQword, in a 32-bit target readInteger().
  • readFloat: Reads a single precision floating point value from the specified address
  • readDouble: Reads a double precision floating point value from the specified address
  • readString: Reads a string from memory until it hits a 0-terminator. maxlength is just so you won't freeze for too long
  • readRegionFromFile: Writes the given file to a specific address
Writing
  • writeBytes: Write the given bytes to the given address from a table
  • writeSmallInteger: Writes a 16-bit integer to the specified address. Returns true on success.
  • writeInteger: Writes a 32-bit integer to the specified address. Returns true on success.
  • writeQword: Write a 64-bit integer to the specified address. Returns true on success.
  • writeFloat: Writes a single precision floating point to the specified address. Returns true on success.
  • writeDouble: Writes a double precision floating point to the specified address. Returns true on success.
  • writeString: Write a string to the specified address. Returns true on success.
  • writeRegionToFile: Writes the given region to a file. Returns the number of bytes written.


Input devices

These functions get/set keyboard/mouse input.

Game Controller
Clipboard


Screen


Sounds

xmplayer


Text to Speech


Fonts


Forms and Windows


Cheat Engine

These functions help manage Cheat Engine itself.

Messages
Input
  • inputQuery: Shows a dialog where the user can input a string. This function returns the given string, or nil on cancel (CE6.4+)
Shortcuts
  • shortCutToText: Returns the textual representation of the given shortcut value (integer) (6.4+)
  • textToShortCut: Returns an shortcut integer that the given string represents. (6.4+)
  • convertKeyComboToString: Returns a string representation of the given keys like the hot-key handler does
Speed Hack


Lua

These functions help manage Lua itself.

  • resetLuaState: This will create a new Lua state that will be used.
  • sleep: Pauses for the number of specified milliseconds


Types

These functions help structure a process's memory into datatypes.


Object-oriented

These functions determine how a Lua object fits in the class hierarchy.


Assembly

These functions help work with the x86 machine code as assembly.

  • autoAssemble: Runs the auto assembler with the given text
  • autoAssembleCheck: Checks the script for syntax errors. Returns true on succes, false with an error message on failure
  • disassemble: Disassembles the given address and returns a string in the format of "address - bytes - opcode extra"
  • splitDisassembledString: Returns 4 strings. The address, bytes, opcode and extra field
  • getInstructionSize: Returns the size of an instruction
  • getPreviousOpcode: Returns the address of the previous opcode (guess)
  • registerAssembler: Registers a function to be called when the single line assembler is invoked to convert an instruction to a list of bytes
  • unregisterAssembler: Unregisters the registered assembler

Auto Assembler


Debugger

These functions manage the debugger. See Lua Debugging.


DBK


Translation

  • getTranslationFolder: Returns the path of the current translation files, empty if there is no translation going on
  • loadPOFile: Loads a ".PO" file used for translation
  • translate: Returns a translation of the string, returns the same string if it can't be found
  • translateID: Returns a translation of the string ID


Files

  • getFileVersion: Returns the 64-bit file version, and a table that has split up the file version into major, minor, release and build]]
  • getDirectoryList: Returns an indexed table with directory names


Structures


Miscellaneous


Besides the above functions, Cheat Engine also implements some classes.

See:

  • setProperty : Sets the value of a published property of a class (Won't work for method properties)
  • getProperty : Gets the value of a published property of a class (Won't work for method properties)
