How is this done? I haven't done much with injecting code but I'm curous how you could say draw a rectangle over a hitbox of an object. Obviously you'd need the coordinates of the object relative to the cameras position to know where to draw, but assume you know the coordinates and where to draw it on the screen. What would you inject to draw a simple dot, rectangle, or text showing a players position on screen in a game using direct draw or direct3D?

Source examples and a brief explanation would be much appreciated.

Thanks.

You'd either need to draw over the entire screen (externally) or hook onto the games rendering engine. As for examples just Google for Direct3D hooks, there are tons of examples / src on the net for it. Same with OpenGL if the game uses that instead for rendering.
