Hi!
I really cannot get out of this.
I've got a class with a constructor declared as:

  this(int delegate(int, int, int, int, int) dg, int startx, int starty)

which is instanciated by another class, with the following statement:

  player = new attore(&urubamba, 2*tilesize, 2*tilesize);

urubamba is a member of this new class which is declared as:

  int urubamba(int where, int altox, int altoy, int bassox, int bassoy)

But when I try to compile, I got the following message:

map21.d(170): constructor map21.attore.this (int
delegate(int,int,int,int,int)bamboleio,int startx,int starty) does not
match argument types (int(*)(int where,int altox,int altoy,int bassox,int
bassoy),int,int) 

map21.d(170): cannot implicitly convert expression
#urubamba of type int(*)(int where,int altox,int altoy,int bassox,int
bassoy) to int delegate(int,int,int,int,int)


but the result is the same... I really cannot understand...

thanks in advance!

`ìnt(*)' means that the reference to `urubamba' is a function 
reference.

Seems that line 170 of map21.d is in the body of the other class and 
not in the body of a function member of the other class.

Within the body of the class the reference to `urubamba' is a function 
reference. Within the body of a function member the reference to 
`urubamba' is a delegate reference.

Indeed it was a silly error: I accidentally left out urubamba from the
class, while editing the file! :) Shame on me:)

thanks a lot!
