javascript - smooth scroll do Y, ne do anchoru

[simPod]

tady je priklad pekneho scriptu na smooth scroll: http://www.dezinerfolio.com/wp-content/ ... croll.html (http://www.dezinerfolio.com/wp-content/ ... th.pack.js)
ja potrebuji pouzit neco presne takovehleho, ale ne aby to scrollovalo na urcity anchor, ale treba do polohy y = 1000px

nevedel by nekdo jak to upravit? ja zatim JS neovladam. dik
