| In b3d if i wanted a simple data structure ie: for a=1 to 10 mt.mytype=new mytype mt\blah=a next for mt.mytype=each mytype print mt\blah next Ive tried to do the same in max obviously changing \ fo . . for \ and each for eachin, but now im getting something about lists? what is this, is the list to be global local? In otherwords where does it fit in to the general scheme of things? The example in the code seems to imply i have to create a list localy and fill it somehow with my entire type structure, simply to recurse all data in said type?!? why does this need to be so complicated? |

| In Bmax the objects *HAVE* to be put on your own list. B3D did this for you (1 big list) but in BMax you can have multiple lists. Try this very basic example... Type TTest Field x End Type mylist:Tlist=CreateList() For x = 1 To 100 mynew:TTest = New ttest mynew.x = x ListAddLast mylist,mynew Next For all:TTest = EachIn mylist Print all.x Next and read this... Beginners Guide <edit> The list can be in any scope you intend to use it. If connected to a type then the list can be defined within the type definition itself. <edit> More OOP way of doing it...
Type TTest
Global mylist:TList
Field x
Function create(x)
If mylist=Null mylist:TList=CreateList()
mynew:ttest = New ttest
mynew.x = x
ListAddLast mylist,mynew
End Function
Method display()
Print x
End Method
End Type
For x = 1 To 100
ttest.create(x)
Next
For all:TTest = EachIn ttest.mylist
all.display()
Next
