I’m looking for a tutorial, or for the scripting to create a mouse trail that has random movement, but that follows the mouse - also i have seen one, ca’t remeber where, that casts ‘shadows’ - any ideas?\r\rthanks to kirupa for cool understandable site. I’m only recently becoming aware of the ease and power of flash.

I don’t really see how a trail can follow the mouse in a random way, but hey, everything’s possible with flash… \rpom 0]

how bout these:\r\<a href=http://www.danalu.com/thoriphes/rm.swf\>[http://www.danalu.com/thoriphes/rm.swf](http://www.danalu.com/thoriphes/rm.swf)\</a\>\r\<a href=http://www.danalu.com/thoriphes/rm2.swf\>[http://www.danalu.com/thoriphes/rm2.swf](http://www.danalu.com/thoriphes/rm2.swf)\</a\>\r\rpretty random, the first follows your mouse at a given distance, and then follows its own random path when you move away. this was an accident, but for some reason, the lil ball gets attracted to the mouse, even when it’s out of the range i set it at. weird, but cool.

wut i meant was i understood the different parts of the code, but i wasn’t sure what each part did. like the friction part i had no idea what the “\*=” did. or that the (Math.random()\*9)-5 was for speed. I didn’t mean that I new exactly what each part meant. I don’t bullsh!t! lol

i might post those two on [kirupa.com](http://kirupa.com) as source files. and jubba, “x \*= 3” is the same thing as x = x \* 3; and Math.random() gets a random number from 0.0 to 1.0 (decimal) and then that num is multiplied by 9, then 5 is subtracted from it. essentially, a random number between -5 and 4. try and follow me here: the least number Math.random() can give is 0.0, which is rare. but anyway, times 9 is 0, minus 5 is -5. that’s the least possible number from this line. now the greatest possible number from Math.random() is 1, times 9 is 9, and minus 5 is 4. what i just should you is a range of random numbers.

actually that’s a random number from -4 to 4.\r:P\rjeremy
