Hi developerno1!

I think I've seen the tutorial a bit ago.....

The camera should be positioned between th etwo players (camera.x) and
the camera should be so far away on the y-axis that you can see the two players at the left and the right border of your screen. (camera.y)

I think it has worked in my project with some "very little" problems....

To solve your problem it would be good to know if the camera is...
1.) ...placed in the air and you see the air and any fighter
2.) ...placed in the air and you see the fighters

You should be aware of the following things...

1.) Using this code your fighters have to be positioned on the x-axis
2.) You have to set the correct angle of the camera (try: pan=90,tilt=0,roll=0)
3.) You should check if the camera is on the same height as the fighters (z=90)
4.) The "pos_camera()"-function should be in a loop

Hope that helps you..;)
