![]() Conveniently these are typically compiled in to a "Assembly-CSharp.dll" or "Assembly-CSharp-firstpass.dll" file. NET apps.īecause we're interested in cheating the game's logic, and not necessarily messing with the Unity game engine itself, we're after the user's Unity "scripts". As mentioned above, Unity games are compiled with Mono, meaning they're. ![]() "Shadowplay" is a "ninja (runner?)" style game in which you have 5 lives and take damage when colliding with enemies or traps:īoth happen to use the same game logic for dealing with damage, for both the player and enemies (so can't just be NOP'ed out)ĭnSpy is a ".NET debugger and assembly editor", which allows you to view the source of. "Beating Heart" is a "beat-em-up" style game with health bars and you take damage when hit by enemies: The game we're going to hack is called " 198X" (part 1), an 80s-arcade themed game with several mini-games.ġ98X has several mini games built in, we're going to be hacking "Beating Heart" and "Shadowplay": exe where we can find a static memory offset to patch. Unlike more traditionally compiled games, these "scripts" are not simply compiled into the. Within the Unity engine, developers can add " scripts" (written in C#) which make up some of the game logic - these will often be our target. Under the hood Unity makes use of " Mono" which is a cross-compiler for DotNet. Developers tend to use Coroutines to continue functions after a wait which spawn a new thread.In this post I'm going to explore a few ways to hack games written using Unity. You can do a scoped search by right-clicking Assembly-CSharp → Scope search to this assemblyīe careful with scripts that affect time. Ignore classes with System and UnityEngine in ILSpy. ![]() You need to use Dissect mono and edit the MoveNext functionĮx: Craft:NewItem is actually Craft+d_15:MoveNext Instead of removing functions responsible for many results, scripts should be specialized into each function for more customizability and stopping bugsĮx: Instead of disabling the function that removes resources, separate it into scripts that stop removing resources on build and on craftįunctions with IEnumerator in their name are separated into different classes. Use ILSpy on DummyDll → Assembly-CSharp.dllįunctions that haven't been called yet in Memory View will have random numbers instead of its address name Wait for the program to finish creating DummyDll folder This is found in GAMENAME_Data → il2cpp_data → Metadata ( C:\Program Files (x86)\Steam\steamapps\common\Nova Lands Emilia's Mission\Nova Lands - Emilia’s Mission_Data\il2cpp_data\Metadata) exe ( C:\Program Files (x86)\Steam\steamapps\common\Nova Lands Emilia's Mission) I will be using Nova Lands: Emilia's Mission There is still a way to search for functions, but decompiling the code is unavailable. This removes helpful info for decompilers and makes hacking difficult. Sometimes, you will find Unity games coded in IL2CPP instead of Mono. Paste this into the script on define(address, HERE) If you need more room, then you can allocate and jump to the new memoryĭo right-click → Copy to clipboard → Addresses only for the first line of the function in Memory Viewer. In this case, Unity Mono game functions usually start with 55, which is 1 byte, and the ret function is C3, which is 1 byte, so this is fine Make sure you never write more bytes than you define WARNING: If your new code takes up more bytes than the old code, then it will break the game, and it will crash. On disable, it will overwrite the new code with the old code If the check succeeds, then it overwrites the address with your code On enable, it will check with assert that the address has those bytes, else it fails and displays a message if you right-click the script once added to the cheat table This script creates two variables, address and bytes Select GAMENAME_Data → Managed → Assembly-CSharp.dll file (on Steam, this is C:\Program Files (x86)\Steam\steamapps\common\Outpath First Journey\Outpath_Data) I will be using Outpath: First JourneyĬlick the Open button at the top left. These will have a folder called GAMENAME_Data with a Managed folder inside. Other people are trying to enjoy the game, so please don't ruin their fun. When finished, feel free to leave a positive review for these fun and passionate games!Īlso, please avoid hacking multiplayer games. The games I chose are free single-player Steam games with Overwhelmingly Positive ratings. This quick guide shows how to hack Unity games compiled with Mono and IL2CPP.
