Bernard,
couple of things:
a) Class "Ressource" uses instance data ("$this->") in the constructor. You
shouldn't call this as a static method (see derived class "Plant").
b) Class "Plant": use the commented-out method in the constructor to access
the ressource's instance data. You should get an error otherwise ($this is
not defined for Ressource::Ressource).
c) Now to your original question: your problem is the class constructor for
"Rain" which receives a COPY of $jungle, not a HANDLE (PHP-speak: not a
REFERENCE) to the jungle object. You should code your Rain constructor like
this:
function Rain(&$jungle) {
$this->jungle = $jungle);
}
This should give you the correct results as far as I can see. If you miss
out passing a REFERENCE instead of a VARIABLE (which would be a COPY of the
jungle object), rain falls in the copied jungle, and your original jungle
remains dry.
Hope this gets you started. As a rule of thumb, always pass REFERENCES when
you're dealing with object handles.
