Hi,

I started using unity a few weeks ago.. and god i love it. but as everything in this world you have to search allot..

i created a Character and added a little Running animation etc.. and so on. well eventually (im making a moba).
i wanted to get the click to move effect. well there are some video's on youtube and i have tried every method.
But the funny...
