   need help with AI in a simple pong clone
  high,well just in the past few hours i have started building my own pong clone. its actually ALOT easier then i thought it would be!!!! i read the first 2 tutorials about SDL at cone3d and figured out how to put bitmaps on the screen. then i put 2 paddles on the screen, then i put a ball. i figured out how to get the ball moving, then i added all the collsion stuff. the hardest part was getting the ball to bounce on an angle when it hit the edges of the paddle, but after some lucky math guesses i figured it out  anyway, the part im up to now is AI. at first i had the enemy move in random directions, well this doesnt work out too well. the enemy is too stupid. so then i had the enemy''s Y position go to the balls Y poistion. well this makes for an un-beatable enemy. how do i get a good balance in between? should i just make a random number 1-100 and if its under 50 have the enemy go to the ball, and if its over 50 have the enemy dont go to the ball? then screw around with the percentages untill i get it balanced?anyway, im not looking for any answers to be handed to me (GASP!). just some hints would be nice. thanks!!
