this does not belong in the Game Design forum. Moving to For Beginners (a programming forum).

There are many reasons why your screen may be all black.

They range from having nothing in the viewport to view, having the lights turned off, to the other end of having your code freeze or crash so nothing gets processed.

Check your console window for messages, and add debug lines to your game objects to ensure they are being processed. If they aren't being processed, use your debugger to figure out where your code is stuck. Sometimes you can find that by pausing the program, sometimes you can use the profiling tools, other times you need to add breakpoints and debug logging to hunt it down.
