<> 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[edit]

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

Returns[edit]

Function — The decoded Lua function.

Examples[edit]

1 local encoded = encodeFunction(function()
2   print("Hello from a decoded function")
3 end)
4 
5 local decoded = decodeFunction(encoded)
6 
7 decoded()

1 local encoded = encodeFunction(function(value)
2   return value * 2
3 end)
4 
5 local decoded = decodeFunction(encoded)
6 
7 print(decoded(21))

 1 local encoded32 = "..." -- encoded on 32-bit Cheat Engine
 2 local encoded64 = "..." -- encoded on 64-bit Cheat Engine
 3 
 4 local encoded
 5 
 6 if cheatEngineIs64Bit() then
 7   encoded = encoded64
 8 else
 9   encoded = encoded32
10 end
11 
12 local decoded = decodeFunction(encoded)
13 
14 decoded()

Architecture Compatibility[edit]

Encoded functions are architecture-dependent.
