## About The Project This is a small project I have been working on for anti cheating in Unity Engine. It allows you to protect your game from cheating tools but it doesn't protect its files from being ripped off. ###### Key Features * Hides variables in memory. * Encrypts and extends PlayerPrefs. * Detects speedhacks. ## Getting Started ### Installation * Download the [Latest release](https://github.com/med9999/SafeValues/releases/tag/1.0.1.0) then extract `SfVal.zip` and place the `SfVal.dll` and `SfVal.xml` files in Assets/Plugins of your project. * It is recommended to build your game with IL2CPP. ## Usage ### Safe Values **These structs hide values from cheating tools by making an offset to them** * Example of hiding a float/integer from cheating tools. ```csharp using Med.SafeValue; using UnityEngine; public class Test : MonoBehaviour { SafeFloat speed = new SafeFloat(500f); SafeInt health = new SafeInt(100); SafeLong plId = new SafeLong(57821103964721L); public RigidBody rb; public void DealDamage(int amount) { health.Value -= amount; } public long GetID() { return pl.Value; } void Update() { rb.velocity = Vector3.forward * speed.Value * Time.deltaTime; } } ``` ### Player Saves **This class saves and loads various data types and classes using AES encryption to playerprefs.** * Example of Encrypting/Decrypting and saving/loading a custom serializable class to/from PlayerPrefs using AES encryption ```csharp using Med.SafeValue; using UnityEngine; public class Test : MonoBehaviour { public Card card; void Awake() { //It is recommanded to set an encryption key, otherwise it is going to use a default key //Warning: always use the same key when encrypting or decrypting PlayerSaves.Key = "/A?D(G+KbPeShVmYq3t6w9z$C&E)H@Mc"; } public void SaveCard() { //will encrypt and save the class in playerprefs PlayerSaves.EncryptClass(card, "card1"); } public Card LoadCard() { //will load the class from playerprefs and decrypt it return PlayerSaves.DecryptClass("card1"); } [System.Serializable] class Card { public string title; public int number; public bool isLegendary; } } ``` * Example of Encrypting/Decrypting and saving/loading values to/from PlayerPrefs using AES encryption ```csharp using Med.SafeValue; using UnityEngine; using System; public class Test : MonoBehaviour { SafeFloat speed = new SafeFloat(500f); SafeInt health = new SafeInt(100); string title = "Plane 1"; char plClass = 'C'; long id = 15120548466974L; DateTime lastSaved = DateTime.Now; bool isActive = true; void Awake() { //It is recommanded to set an encryption key, otherwise it is going to use a default key //Warning: always use the same key when encrypting or decrypting PlayerSaves.Key = "/A?D(G+KbPeShVmYq3t6w9z$C&E)H@Mc"; } public void SaveValues() { //will encrypt these values and save them in playerprefs speed.Value.EncryptFloat("plSpeed"); health.Value.EncryptInt("plHealth"); title.EncryptString("plTitle"); plClass.EncryptChar("plClass"); id.EncryptLong("plId"); lastSaved.EncryptDateTime("plLastSaved"); isActive.EncryptBool("plAct"); } public void LoadValues() { //will load these values from playerprefs and decrypt them speed.Value = PlayerSaves.DecryptFloat("plSpeed"); health.Value = PlayerSaves.DecryptInt("plHealth"); title = PlayerSaves.DecryptString("plTitle"); plClass = PlayerSaves.DecryptChar("plClass"); id = PlayerSaves.DecryptLong("plId"); lastSaved = PlayerSaves.DecryptDateTime("plLastSaved"); isActive = PlayerSaves.DecryptBool("plAct"); } } ``` ### Anti-Speedhack **This class detects speed hack attempts** * Example of setting up an anti speed hack to detect speed hacks ```csharp using Med.SafeValue; using UnityEngine; public class Test : MonoBehaviour { void Awake() { //starts the anti speed hack detection process and calls CloseGame() when a speed hack is detected StartCoroutine(AntiSpeedHack.Start(CloseGame, 2f, true)); } //This will be called if the AntiSpeedHack class detected a speed hack void CloseGame() { Application.Quit(); } } ``` ## Demo Try a WebGL [Demo](https://ookii-tsuki.github.io/SafeValues/index.html) ## License Distributed under the MIT License.
