Multiple Instances of one class

K, here’s my problem. I have one class called Vehicle I get it to move by making a path array and having it follow that path. The thing is, when I create more than one instance of that class, those instances all share each others variables(meaning same path array values). So only on of the instances moves the way I want it to while the others stand still. Help? I want it so that each instance has it’s own path array that can get updated so each one follows their own path. Thanks.
