Re: [Gambas-user] Multidimensional dynamic array basics
Well you need to understand that you make an array of array of models To fill it : Public StageListWall As New ObjModel[][] StageListWall.Resize(200) 'Instanciate each x Level For i = 1 to StageListWall.Max StageListWall[i] = new objModel[] next 'Adding a Model : hModel = new ObjModel StageListWall[0].Add(hModel) 'To get the Model name if you have a property name : StageListWall[0][0].Name To Delete a model StageListWall[0].Delete(0) To clear All model of x level StageListWall[x].Clear Well i prefer far this kind of array and use it more than the multidimentionnal way. At gambas begin there was only Objects and array of objects... so the Array of array was the only way to get multidimentionnal array. I have not found any qualities to the multidimentional way .. maybe the speed ?

To bring context to the situation, in each stage there are x number of wall positions and y number of wall models per position, so assuming I can add elements to StageListWall[][] when loading the wall model display lists I would be able to access/refer to them like this: StageListWall[Position][DisplayList] There are an arbitrary number of positions and display lists per position. I also can't seem to refer to the length of individual arrays, such as by doing: StageListWall[].Length or StageListWall[][].Length The basic logic is that I would be referring to an individual display list using two numbers, position and list index. The display list itself would be the element value. If it were a static array it would look like this: Public StageListWall[1000, 1000] as ObjModel StageListWall[Position, DisplayList].Draw The logic for the static array is dead simple, yet translating this to a dynamic array is just killing me. Obviously I can just implement it as static and make it work, but I'd like to do it the proper/efficient way if it's possible.

Re: [Gambas-user] Multidimensional dynamic array basics
Personally, I like to think of a 2D array of integers as a 1D array of objects, with each element an array of integers I've done something like this with complete success: ' Public rec As New Object[100]'declare rec as an array of objects and create it. ...then... in Sub _new() Dim i As Integer Dim ia As Integer[] 'This declares what ia is, but doesn't create it yet For i = 0 To 99 ia = New Integer[10] 'This creates a new array of integers[0..9] each loop rec[i] = ia'Each element of rec[] now contains a created Integer[10] array Next ' ...something else... rec[15][3] = 86400 'just like a 2D integer array rec.delete(7) 'will remove rec[7] (the whole integer array at rec[7]) and bumps down whole arrays rec[8]..rec[99] to be rec[7]..rec[98] rec[20].delete(3) 'will remove the rec[20][3] element. (a single integer) 'so, rec[20] is an Integer[] with 9 (not 10) elements: [0]...[8] rec[46] = rec[45] 'The Integer array at rec[46] pointed to is gone. Poof! Vaporized. 'rec[46] doesn't point to it anymore. 'rec[45] and rec[46] point to the same identical integer[] array 'which originally was created as rec[45] 'Then, if you wrote rec.delete(45), the array would not be gone because 'rec[46] still points to ithowever, the .delete moves everything 'down one element: rec[46]..[99] is now rec[45]..[98] Swap rec[40], rec[41] 'the whole integer[] arrays 40 and 41 are swapped. 'data is not copied, just the pointer to the arrays are. ' ..something else... Dim s as String[] s = New String[] rec.add(s,92) 'rec[0..91] each are an Integer[10] array 'rec[92] is a String[] array with 0 elements. 'rec[93..100] each are an Integer[10] array rec[92].add(HELLO) 'rec[92] is now a String[] array with 1 element... 'which is: rec[92][0] = HELLO ' ..some where else... ' I want an array of 500 Labels in rec[50] Dim L as Label Dim i as Integer Dim o as New Object[500] 'declare AND create a new Object[] array with 500 elements rec[50].add(o) 'rec[50] Integer[] is now rec[51]. Everything bumped up one [] For i = 0 To 499 '...and rec[50] is an Object[500] L = New Label 'create a New Label rec[50][i] = L 'now rec[50][i] points to the new label Next 'Every one of the 500 Labels in rec[50] are created and unique '..and you could display each of them on a Form. '- It can get quite interesting because this works with any objects including GUI Labels, Timers, Strings, Structs, Panels, and so on. (when doing GUI things, you also have to connect them to event handlers too ...I didn't write that here) The most important part is to understand the difference about DECLARING variable names (for the program to compile) (using DIM or Private or Public) and CREATING new variables at run-time. (like ...As NEW Object[500] ...As NEW Label) I'm pretty sure I got the syntax right. -Nando -- Original Message --- From: Kevin Fishburne kevinfishbu...@eightvirtues.com To: mailing list for gambas users gambas-user@lists.sourceforge.net Sent: Wed, 19 Aug 2015 02:22:54 -0400 Subject: [Gambas-user] Multidimensional dynamic array basics I need to know how to declare, initialize and add elements to a two-dimensional dynamic array.
