Change 3 to 3.0 and you will see it works. Hope this helps. Re: Koch Curve in Python 14 Years Ago by richieking Its turtleworld your own written module or what. ;) Re: Koch Snowflake 16 Years Ago by sciwizeh your vertex variable is holding a number too high, i am trying to figure out why Re: Koch Snowflake 16 Years Ago by sciwizeh vertex is actually the right number, found it, your trying to draw with the new number of points before making the points, put your paintComponent(g); at the end of the method Re: Koch Snowflake 16 Years Ago by sciwizeh ok... the problem is right, i think, but the solution causes the same problem Re: Koch Snowflake 16 Years Ago by LevelSix Yeah, I think you're right. That is why I mentioned the arrays. Is there a simpler way to convert arraylists to an array? Re: Koch Snowflake 16 Years Ago by sciwizeh well, i would re-arrange the two paint methods, to avoid using the arrays before making them. i don't know whether it would make a difference to the returned array, but i would also try adding a call to trimToSize() call before toArray() another thing you could do to avoid the casting to array type, you could look into the [URL="http://java.… Re: Koch Snowflake 16 Years Ago by LevelSix I placed int variables in the draw method, and the paint method that are derived from the size of arrylist x. After draw is done being called, the size is 6. After the program moves on to paint, the size is 0. This is where the problem lies. Re: Koch Snowflake 16 Years Ago by sciwizeh that's weird. Re: Koch Snowflake 16 Years Ago by LevelSix Very. I can't for the life of me see why it does this.
