array of lists

I need an array of lists OR a map of lists

e.g. global map_square_item_list:tlist(50,50)

but it keeps saying it cant reference it when I try to add a type to one of the lists

so, how would I create an array of lists and add a type instance to the list?

Blitzmax arrays use square brackets.

Also, make sure you loop through the array and initialize each new list before you use it -- otherwise you'll be adding objects to null lists.

This should work:

Global mapList:TList[50,50]

For Local x:Int = 0 To 49
	For Local y:Int = 0 To 49
		mapList[x,y] = CreateList()
	Next
Next

What are you *really* trying to do?
Do you really want a 50 by 50 array for lists?
It really makes things easier if you post the code you're having problems wit.
Here is a simple example :

Local array_of_lists:TList[2]
Local list1:TList=CreateList()
list1.addlast("1")
list1.addlast("2")
list1.addlast("3")
Local list2:TList=CreateList()
list2.addlast("7")
list2.addlast("8")
list2.addlast("9")
array_of_lists[0]=list1
array_of_lists[1]=list2
For Local x:Int=0 To 1
  For Local all:String=EachIn array_of_lists[x]
	  Print all
  Next
Next

<edit> Arrggghh you edited your post.

thanks all, I got it working now

Don't know what you're doing but if you're doing a tile/grid based game, then instead of having seperate arrays of lists like items[x,y] enemies[x,y] etc try making a cell or square type, having these lists as a field and an update/draw method. It might make things better organised. I can give an example if you like.

i used arrays to help with pathfinding speed,
thanks for the help
