Another question:)

Can the foreach command be used on a multidimensional array.I have tried using the following code but it only shows one line

// Project: alpha
// Start: Sunday, July 22, 2007
// IDE Version: 4.237


   LOADSPRITE "red.png", 1


   LOADSPRITE "green.png", 2


   LOADBMP "background.png"

   TYPE ball
   x
   y
   colour

   ENDTYPE

GLOBAL balls[] AS ball
DIM balls[9][9]

   FOR y=0 TO 8
   FOR x=0 TO 8

    balls

[y].x=x*64

balls

[y].y=y*64

balls

[y].colour=RND(1)+1

      NEXT
      NEXT

WHILE TRUE

ALPHAMODE -1

foreach item in balls[]
xx=item.x
yy=item.y
col=item.colour

sprite col,xx,yy
next




SHOWSCREEN

WEND

No. It only acts on the first array index. Multidimensional arrays will return the first item

always. Sorry.

No problem Gernot.I will just use a nested for next loop instead.Thanks for the quick reply.
