Mouse Movement Problem

I managed to get this working with a keyboard but i'm having some problems with the mouse

When i give it somewhere to go, and when it arrives it switches sides fast before it goes to idle ?!

(it might have something to do with the 8 way movement deceleration but changing the values doesnt solve the problem just makes it look a bit different)

what i'm i doing wrong.

nevermind, figured it out

replaced 8 direction movement with path finding and now it works like a charm
