<> Lua API Reference

function decodeFunction(string) : function

Converts an encoded function string back into a callable Lua function.

The encoded string must have been created for the same architecture as the current Cheat Engine process. A 32-bit encoded function can only be loaded by a 32-bit Lua state, and a 64-bit encoded function can only be loaded by a 64-bit Lua state.

Function Parameters

Parameter Type Description
string String The encoded function string created by encodeFunction.

Returns

Function — The decoded Lua function.

Examples

local encoded = encodeFunction(function()
  print("Hello from a decoded function")
end)

local decoded = decodeFunction(encoded)

decoded()

local encoded = encodeFunction(function(value)
  return value * 2
end)

local decoded = decodeFunction(encoded)

print(decoded(21))

local encoded32 = "..." -- encoded on 32-bit Cheat Engine
local encoded64 = "..." -- encoded on 64-bit Cheat Engine

local encoded

if cheatEngineIs64Bit() then
  encoded = encoded64
else
  encoded = encoded32
end

local decoded = decodeFunction(encoded)

decoded()

Architecture Compatibility

Encoded functions are architecture-dependent.
