![]() ![]() Again, the data in memory keeps changing even when the value doesn’t (I’ll explain why it happens later), so “fuzzy scan” doesn’t work either here!! That’s a master kill!īesides of keeping mask changing, it also keeps reading the value out and writing it back, which kills most game editing tool “value frozen” feature! Unless you can ensure you freeze the mask and hashed value at the same time, or it breaks the value! Since the reading and writing happen in a very high frequency (Again I’ll explain why it happens later), so you have to lock down the value at a specific point, or the locked value will be overwritten immediately.įurthermore, since this value is the key game value, which is displayed on Game UI all the time, the getValue() is called every time when game UI renders! And usually game UI renders in at least 60fps. This kills the almost all kind of memory scanning features in all kind of game hacking tool! You cannot find the plain value in the memory, so you have to use “fuzzy scan”, which detects the values changes instead of scanning specific value. And every time, when either the value being read or written, the mask changes. Instead, it stored a “hashed” value, which is the plain value xor a random generated mask. So from the code, you can see, the plain value is never got stored in memory. Here is the psudo-code explains how the it works: HiddenInt Psudo implementation In fact, Harvest uses a quite unique approach to protect its game status data! Oxeye guys call it the Hidden Int. For the full list of new features in the 2.6.0 series. Among other things, the release adds support for Klipper firmware flavor, extends capabilities of custom G-codes, improves Arrange function, enhances Export to STL to subtract negative meshes, and fixes bugs found in previous alphas. But we can easily find that the value is only used for display instead of real game state data. This is another alpha release of PrusaSlicer 2.6.0. By searching the mineral value, we can locate a specific address. Very standard approach, and supported by most of the game hacking tool.īut in Harvest, the story is quite different. And finally figure out the proper address, then locked it down with the game hacking tool. A common application for this is for cheating in video. Scan the memory for specific number for a few times to filter out the list of potential memory addresses. Side note: Bit Slicer works with native games, and I think Cider ports and the such should be fine. Theoretically locking down a value is easy. Basically it determines symbols using peak polarities and distance between peak. The approach I chose to take was to make the Custom Range bookmark have the Current page option set so that the user was always returned to the first page in the report if they selected that option. ![]() Mineral is the only key resource in the game, which is used to build or upgrade structures. Using the information of peak positions, a bit slicer recovers symbols. The tricky bit comes with the showing and hiding the slicer as you can only show and hide a visual on the current page with a bookmark. I will discuss something interesting I discovered when hacking the game.īy hacking the game, I want to lock down the the number of Mineral that I have in the game. The game is amazing, but I won’t focus on that. • Enjoy OS level features such as auto-saving, document versioning, window restoration, notification center, etc.Harvest: Massive Encounter is a very unique strategic tower defense game published by Oxeye Game Studio.
