What is supposed to happen:
Each second, a slime will go into one of the directions:left, right, up,down, or it will stand still. Each of these actions have a 1/5 chance of happening. However, what happens is, all the slimes go to the left for 1 second and stop... forever. What am I doing wrong?fassFlash2013-05-04 11:20:27

Random doesn't produce whole, rounded numbers.

This means that random(4) will give you anything from 0 to 3.999r, with 1.89237783 and 2.12301203 and everything else in between. You should use round(random(4)) to get a whole random number from 0-4.

Posting the .capx itself is way better, you can see the code with .capx and find out what is going on, and downloading the .capx is less time consuming for everybody including me than post it on scirra arcade. See that link?

@sosensible, uploading to the Arcade is a waste of time for these quick fixes. People much prefer to download the capx directly from Dropbox - it's hardly a random site :P

yes but one person uses drop box and another person uses another site and people don't always like jumping from sight to sight

@geometrix
@fassflash

using round(random(4)) will give a slight bias to numbers 1,2,3

for example to return 0, it needs to be between 0 and 0.5, but to return 1 it needs to be between 0.5 and 1.5.. which is more likely

doing int(random(5)) will give the same chance for each number 0 to 4

@keepee, ah, cheers for that. Makes sense.

@sosensible, Dropbox is the de facto standard for sharing files around here.

So, what's better, jumping from sight to sight or being unable to solve the problem?
