Errors?

  • Getting the vertices > 60000 error message?
    A lot of users report getting the vertices > 60000 error message, this is as far as I know a Unity bug, I can unfortunately not do anything to fix it.
    It might help to turn off Show Unwalkable Nodes, or to turn off Show Graphs altogether.
    [Update] According to what I have heard, this is now fixed in Unity 3.5.3J
  • Getting errors in MonoDevelop where the functions contains default parameter values?
    Select: Tools > Preferences > Unity > Debugger and turn off "Build project in MonoDevelop".
  • Getting errors where some classes in the A* Pathfinding Project do not seem to have some members they ought to have. Check for if any of the classes in your project have a name identical to one in the A* Pathfinding Project and if so, change the name of them or put them in a namespace. It will cause trouble if they are in the global namespace. I try to put my classes in namespaces, but unfortunately it will still cause troubles if ANY of the conflicting classes is in the global namespace.
