Pong AI

hi,

I'm trying to replicate the classic game Pong.

I thought it should be easy to make a 1 player vs computer game, but I can't make it work.

I've tried something like this:

Computer player = 8 directions, 2 up 2 down

Every tick ----> set computer player Y position to ball.Y

It works but the computer can't be beaten.

Is there a way to add some delay?

Thanks

I once wrote a 1 player pong game to see how few events I could write it in. It's all in 2 events, so it uses some advanced tricks. But you can see the AI paddle moves in the direction of the ball, but at a set speed, so it is possible to get the ball past the computer player. If you set it directly at the ball position, there's no way to sneak it around.

Play it here: https://dl.dropboxusercontent.com/u/854 ... index.html

or here is an image of all the events:

..

The simplest of all is changing "Every tick" to "Every X seconds" (0.05, 0.1, 0.15, etc), that will add a delay to the AI movement. Moreover you can set the seconds to random() that will add a bit of realism. Do a bit of testing and eventually you'll get it right.

Every 0.05 seconds -> Ball.Y < Paddle.Y -> Paddle simulate pressing UP (reverse for DOWN).

thanks guys! it's working now
