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. |

| 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. |
| ||
| well then you're stuffified :) |

It's scary that this works though:Local map:Int[][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][][]..

| 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 |

| he wants to auto-initialize them as well, which BMax can't do. |
| ||
| tonyg: Nope, that isn't what I was looking for. |
| ||
| OK, I understand now. |
| ||
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 :) |

| . that was silly ^^ |
