Hi Mauer, It sounds like you need to split your list of 200 objects randomly into 2 lists. Here;s 2 ways of doing that.
1) Using the [Random] component, generate N random numbers, where N equals the amount of surfaces. Then compare each random number to a fixed value. You can use an Expression with 2 variables (x,y) for this. The expression is "x < y". This comparison will give you a list of Boolean values which you can then use in a [Dispatch] component. 2) Feed your surfaces into a [Jitter] component, and then use [Split List] to break your randomized list into 2 parts. -- David Rutten [email protected] Robert McNeel & Associates On Mar 17, 7:28 pm, mauerhakenzwerg <[email protected]> wrote: > hey, > got a problem, as still learning grasshopper: i got about 200 surfaces > and want to random select a certain percentage of them (with a > slider?) and change their colour- but how can i do that??? i guess for > you thats easy but i really have problems with unterstanding how this > could work- (maybe because of my bad english- i do not really > understand the random function) > > would be great if somebody could help me > mauerhakenzwerg
