Error and Set position by transform

[manurocker95]

Hi! I have an object which i need to drag from the point I touch. Now I'm moving it by transform, but I can't do that as the object doesn't move. When using handles, i'm getting this error:

transform.position assign attempt for 'Ball' is not valid. Input position is { NaN, NaN, NaN }.
