I dunno why it was deprecated, but:  
random(2) is not the same as Math.round(Math.random()\*2);

random(2) return an integer between 0 and 2, not including 2;  
Math.round(Math.random()\*2) return an integer between 0 and 2 (included).

i guess Macromedia whated to do it all in a more OO way :sure:

oh this should be better

```auto

random(2) = Math. **floor** (Math.random()*2);

```

I don’t really know why, but i assume it has something to do with the fact that after flash 4, ActionScript followed the ECMA standards 🙂 … the old random() is faster than Math.random() though :-\

I remember someone saying that Math.random() is more random than random() but I see no difference! :-\

someone here did a really good thing on how random is random, plugging in the values in excel and making a chart and everything - that was pretty wild, but I dont think they compared random to Math.random. I think it was just random. … so I dont know if one is more random than the other or not :-\

… I think I might have heard the same though

i guess it just goes back to having everything more object oriented like you said before.
