Arrays of a 2d Arrays Madness!

Ok I've got in a bit of a pickle. Conceptially it works out.

I have some small 2D grids in [,] format. I want an array of these. Conceptially I don't want a 3D grid, just a series of 2D grids.

To make it worse I need to be able to send a 2D grid as a parameter to a function.

I've done some experimenting but not suprisingly no luck.

For a start should I be doing array[][,] or array[,][]?

And these are arrays of a type so I'll be needing to new them.

And finally pass one as a parameter like func(array[i]).

Sorry for all these questions!

SuperStrict

Local array%[20,20]
foo(array)

Function foo(n%[,])
End Function

Thanks but that only makes one 2D array. I'm looking to have an array of 2D arrays.

maybe this


SuperStrict

Type SetType
	Field array:Int[10,10]
End Type

Local maps:settype[10]
foo(maps)

Function foo(n:settype[])

	For Local i% = 0 Until 10
		n[i] = New settype
		For Local y% = 0 Until 10
			For Local x% = 0 Until 10
				n[i].array[y,x] = Rnd(100)
			Next
		Next
	Next
End Function

That's looking better. I was hoping to do it without introducing a new type but I guess it would be an easier to use solution.

I'm at work, so can't test, but wouldn't this be an array of 2D arrays?

Function foo(n:Int[][,])
End Function

Looks like it.

yes, but how do you declare an array of that format?

this is what I have:

SuperStrict

Local array%[,][]
array = array[..10]
For Local i% = 0 Until array.length
	array[i] = New Int[10,10]
Next
foo(array)
Print fun(array)
Function foo(n%[,][])
	For Local i% = 0 Until n.length
		For Local y% = 0 Until 10
			For Local x% = 0 Until 10
				n[i][x,y] = Rnd(10)
			Next
		Next
	Next
End Function
Function fun(n%[,][])
	For Local i% = 0 Until 10
		For Local y% = 0 Until 10
			For Local x% = 0 Until 10
				Print n[i][x,y]
			Next
			Print "++"+y
		Next
		Print "======"+i
	Next
End Function

see how I created it and how I am using it. it doesn't make sence. the declaration doesn't match the usage. I tryed to do it the correct way and I keep getting errors.
is this a bug? or is there something I don't understand?

*EDIT*
removed cos' it's crap.

I would imagine that the declaration is that way because the type specifier precedes the array

i.e. f:Float[] is a float array
so f:Float[,][] is an array of float arrays.

or something like that.
