Random X direction

Hi,

I'm doing a pong tutorial where the ball always goes by force physics to one direction. I would like to randomize the X direction to start negative sometimes (facing the other player).

For that matter I made a numeric variable 0,1 where if 0 the ball goes to positive velocity, 1 it goes negative.

The ball wont move if it's set to random. What am I doing wrong?

Here's this script:

start with an absolute value. abs(value here). It will always start possitive becasue absolute values ignore Plus and Minus.

Random(0,1) returns a random floating point value between 0 and 1. You might want to try choose(0, 1).

Thank you very much guys. Choose does the job.
