 Posted: Wed May 25, 2016 4:07 pm Post subject: How to C# In-game overlay for Trainers? |
 |
|
I am trying to figure out how it is possible to create a C# Program that gives you an in-game overlay that displays some cheat options.
I have made trainers using C# Window Applications, but I am interested learning more and finding out how to create in-game overlays where I can display various options, such as "Unlimited Health: Enabled" just so the user wont have to minimize the game in order to see the trainer status/options. 
Any and all help will be much appreciated - especially if it points me in the right direction

Create a transparent layered window that is top-most.
You can set those properties via SetWindowLongPtr using:
- GWL_EXSTYLE
- WS_EX_COMPOSITED | WS_EX_TRANSPARENT | WS_EX_LAYERED
In C# you will also need to enforce user drawing and paint the form yourself for proper overlaying. You can do that via:
| Code: | this.SetStyle(ControlStyles.UserPaint | ControlStyles.AllPaintingInWmPaint, true);
|
Every so often you can find the window you are trying to draw over and reposition your overlay as needed etc.
On newer systems (Windows Vista and higher) the Dwm API will be of interest as well to deal with various window sizes / Aero effects:

As I understand it; this will only work when playing in Windowed mode; otherwise I would need... injection or something? Read that I might have to use DirectX or something. Unsure about the specifics. :X

Yes, an overlay like this will only work on Windowed Mode / Fullscreen Windowed Mode games.
If you want to render things in the game, that's not really considered an overlay then. You'll have to either hook the rendering engine being used (OpenGL/Direct3D/etc.) or hook the games engine and use its own functions to draw things etc.
