Cheat Engine

[hyphen]

Hello out there I was wondering how programs (like say Fraps) can display variables/strings (like say your FPS) on top of full screen games (without making the game subsequently minimize).

Can it be done with dialog? And if so maybe a few hints on how that would work mmmm?

What I am trying to do is display my coords in the corner of my screen for a fullscreen 3D game. I can read the coords, and output them to a text file or whatever, but my win32 GUI knowledge is extremely basic so I have no idea how get anything to show up on top of the game.

All help/tips are appreciated~

p.s. C++ is all I know/understand

You could use DirectDraw to overlay the coordinates onto the screen. Here's a DirectDraw Overlay Library

You'll probably find that overlays are:


1. Finicky with driver support. ATI supports RGB, Nvidia doesn't, you have to convert to YUV.

2. Crappy and likely don't work over most full screen applications anyway.

3. A pain in the ass because directdraw is shitty.


You're probably better off just using the games own renderer.

slovach - I'm interested as to how one would go about using the game's own renderer to do this... care to post a sample?

[hcavolsdsadgadsg]

You can do a couple things really, you can use in-game functions to display menus, etc.

You can inject your own drawing code and just jump to it when the game is done doing its own. This is pretty straightforward.

But ultimately, the smartest way is likely hooking the renderer and you can go apeshit with DX fun after. There's an article on gamedev about this.
