Static Variables Obfuscator UE4

This code plugin for Unreal Engine 4 obfuscates any static (non-dynamic) variable so it is very difficult to locate this variable in the memory.

This makes using tools like Cheat Engine to manipulate in-game data a non trivial task.

How to use it?

Simply wrap a declared variable with TVarOb keyword and it will obfuscate it.

int32 X;            // Not obfuscated variable :(
TVarOb<int32> Y;    // Obfuscated variable :)

Obfuscated variable can be manipulated in the same manner as normally

TVarOb<int32> X = 1;    // Assing variable
X += 10;                // Increase variable
int32 Y = X;            // Get variable

Using it with structs

Unfortunatelly to modify obfuscated struct it has to be unencrypted first.

struct FSomeStruct
{
    int32 X;
};

TVarOb<FSomeStruct> Foo;

FSomeStruct Bar = Foo;
Bar.X += 10;
Foo = Bar;

What types are supported?

Currently it supports all arithmetic types and the following structures:

• FTransform
• FVector
• FVector2D
• FRotator
• FQuat
• FColor
• FLinearColor

Theoretically it should work with any struct that doesn't contain dynamic variables (pointers, strings, arrays, etc). However it implements a check to ensure only verified structures are used. If You want to You can add a proper trait check to the VarObSupportedTypes.h.

Serialization

You can serialize obfuscated variable into a file so it will be obfuscated in file as well! In order to do this TVarOb can be imported and exported to an array of bytes using the following methods:

void ToArray(TArray<uint8>& OutData);
void FromArray(const TArray<uint8>& InData);

These arrays can be saved and load using the serialization method of Your choice.

Blueprints

This plugin works the best with code but there are some structures and functions that allows to use it with Blueprint too. For more details check VarObBPLib.h file.
