2D Arrays.

| Hay all. ok so I needed to make a 2D Array, now TBH with you I couldnt get it to work, I was trying something like this. Global MyArray:int[][]=[[1,2][3,4]] Print MyArray[1][1] What I was expecting was "3" as an output or "1 3" but what I got was "4" the above example is taken from another array post in which he used strings but the idea is the same. Anyway What I actually want would look like this in Blitz3D. Dim Array$(2,2) Array$(1,1)="1" Array$(1,2)="2" Array$(2,1)="3" Array$(2,2)="4" So if I wanted 3 Id do this. Print Array$[2,1] I have now worked out how to do this in Max and thought I would share it. Global Hscore$[5+1,2+1] For looper%=1 To 5 Hscore$[looper,1]="Name-"+String(looper) Hscore$[looper,2]=String(100*looper) Next For looper%=1 To 5 Print Hscore[looper,1]+":"+Hscore[looper,2] Next What the above Bmax code does is create a 2D Array, with 5 Elements in the first section and 2 in the last, I will be using this as a high score array, 5 positions and storing a name and socre in each. My question at this point is what the hell is the +1 for. ?? GOOD TIP <<<< To get the above code what I did was code it in B3D and then imported it to max to see how it wanted it done. |

| I think it's because array sizes are exactly as numbered i.e a[5] will create 0-4. rather than B3D giving 0-5. To loop 1 to 5 they've simply added an extra element to the array. |

| i think the way max does arrays is wrong. any form of basic has always used 0-value. Some even having a MIN perameter for the dim statement. if you do the equivalent of Dim Array(5) in max, if you try to access the 5th element, you get bombed. I just found that a bit odd to be honest. Oh well, not particularly hard to fix :/ |

| what basic does, does no one really interest all real languages have arrays like used in max from 0 to number_of_elements - 1 the way blitbasic did it was just wrong! if you declare an array with 5 elements it has to have 5 elements not 6 there is another reason for this behavior: Streams etc are adressed with [x] as well where x is the memory position which starts at 0 and not at 1 ;) |

| Dreamora is right here the Array Should start at 0 I was only wondering why max Added the +1 |
