[Gambas-user] Arrays of Structs

[Jussi Lahtinen]

Seems that the arrays remain uninitialized... I'm not sure why.
Do you really need embedded arrays and structs? They are mainly for
interacting with libraries written in C, and using Pictures inside of the
struct kind of contradicts that.

I'm mean that all works if you do it with classes and initialize the arrays
as:

   '' In MapRoom class
   Public MapObjects As New MapObject[50]


  '' And this where ever you need it
  Static Private WorldMap As New MapObject[100, 100]
