Camera Systems

[Jajjo]

Hey there.

I have made a new camera system and I'm having a sort-of issue.

The attached image (Untitled.jpg) will be the image I refer to when I say pink, orange, green or whatever. The black square is my camera and the gray square is a cube that I created to test the camera with.

The image (Untitled2.jpg) is the result of rotating the camera around the X axis by 45 degrees.

I am concerned, because I would expect the cube in Untitled2 to be coming into the frame from the bottom of the screen. When I rotate the camera around the X axis by 45 degrees I'd expect it to follow the pink line. It's not doing that and seems to be following the orange line.

I think I'm missing a step in the creation of the camera. Or I'm not doing something. It's odd. It's like the camera is facing down the blue line. What am I missing?

Thanks for any help and I can provide more info if necessary.

Ok. I sorted it.

Turns out I forgot that using cameras requires you to use the opposite sign for the direction you want.

I was actually moving my camera below the cube, which is where all the odd behavior came from.

Everything is working now.

Ok, I have a new problem.

Currently the mouse coordinate returns the position at the blue dot being 0, 0. How do I make it so that the 0, 0 is at the GREEN dot?

I'm currently getting the cursor position with GetCursorPos() and then subtracting the windows x and y position from the cursors current x and y position.

Never mind.

Sorted it again.

Got the cursor position with GetCursorPos(), then used ScreenToClient() to convert it from screen coords to the client area coords. Worked perfectly.
