This probably isn't the best way, but it should work, and was the first idea that came to mind. What don't you have Alice select a random number, and then have an if/else method that basically says that if the random number equals this then have the person turn this direction, otherwise, have him turn this direction. You could also put an if/else loop within an if/else loop to make the randomization even more random. I hope this helps!

Or you could use the "Choose true" function and have it "choose left" within an if/else 25% of the time, right, forward, and back. So something like this

IF choose true (25%)
Person move forward
ELSE
IF Choose true (25%)
person move left
ELSE
IF Choose true (25%)
person move backward
ELSE
person move right

I didn't understand any of that, which is probably why I didn't think of it.

Make a list with all six directions in it, then drag the list to wherever you need a random direction, and select random_item_from_world.nameOfList

I think I get what he is trying to say.

Since this a random chance without replacement, you can't just have the first one at 25% and continue from there. After you rule out the first one, there are only 3 left, so you need the next one to be at 33%. Then 2 left, so 50%, then 1 left, 100%.

Thanks for the correction. Though I do think that ElectricKirby's idea is the easiest, now that I see it.
