How do I randomly generate specific numbers?

I have a waypoint system set up I would like to do, to move enemies around, without the pathfinding behavior.

When they collide with specific waypoints, it will change their direction based on a number value.

The problem is, I don't want it to always choose all 4 random numbers. Sometimes, I would want it to pick a random number out of 2 numbers, or 3 numbers, so how would I do that?

I know how to randomly generate the 4 numbers, but what would I do if I wanted it to set it to either 0, or 2? Or 1 and 4, or 0,1 and 4?

thanks!

Try choose(n0,n1,n2), or just use int(random(4)) would get 0-3 which you can reference 0 do this, 1 do foo, etc.

two different options (event 1 or events 2 and 3)

use instance variables for enemy..

var=1 ..choose(1,4)

var=2 ..choose(0,3)
