I am relatively new to matlab programming, I have a solid basis in Java, but am now learning matlab for an engineering class I am in.

In this class, we have to make a game in matlab, and my game involves taking user input to move a player sprite.

My game is supposed to run at 5 frames per second, and it works up until the point that I need to take user input.

The function I am using to determine what key the player is pressing waits until it sees an input for the user. This is fine when the user is pressing a key to move, however, I still need the game to run even if the player is not making input.

I basically want to have an if statement along these lines

if(a key is being pressed)

key = keyBeingPressed;

end

This would solve my issue, because keyBringPressed is the function that pauses the code until a key is pressed. However, if I only run that code when I know a key is being pressed, then if no key is being pressed the program will move past that point and will continue to run at the desired framerate.

Does anyone have a sugguestion for how to implement this?

Thanks
