Initializing multi-dim arrays

How do you do it, 'cause I know this doesn't work:

Local map[,] = [0,0,0]

Funny thing is though, that the error for that line is:

[ERROR]: Compile Error: Unable to convert from 'Int Array' to 'Int Array'

I'm just laughing my arse off at that.

Perturbatio

you can't initialize a multidimensional array.
But you *can* initialize an array of arrays:

Local map[][] = [[0,0,0],[1,1,1],[2,2,2]]

You can index them in a similar fashion to a multi-dimensional array:

map[x][y] = 100

Yeah. An array of arrays isn't what I want.

Perturbatio

well then you're stuffified :)

It's scary that this works though:

that *is* scary, what's scarier though is that you tried it!

Isn't this what you're looking for...
http://www.blitzwiki.org/index.php/Arrays
Multi-Dimensional Arrays
To create an array with more than one dimension, you can specify indexes seperated by commas:

Local int_array1 : Int[4,4] 'create a 4x4 array
Local int_array2 : Int[3,3,3] 'create a 3x3x3 array
You can then refer to them like so:

int_array1[0,0] = 100
int_array2[2,1,0] = 1000

Perturbatio

he wants to auto-initialize them as well, which BMax can't do.

Nilium

tonyg: Nope, that isn't what I was looking for.

OK, I understand now.

Perturbatio

#11

you *could* kludge it:

Local ar:Int[2,3] 
init2DIntArray(ar, 2, 3, [[0,1,2],[3,4,5]])
Print ar[0,0]
Print ar[0,1]
Print ar[0,2]
Print ar[1,0]
Print ar[1,1]
Print ar[1,2]

Function init2DIntArray(array[,] Var, width:Int, Height:Int, vals[][])

	For Local x = 0 To width-1
		For Local y = 0 To height-1
			array[x,y] = vals[x][y]
		Next
	Next

End Function

That idea isn't particularly appealing.

I never said it was appealing :)
