Numbering system / base used for object ids

[sethmachine]

Hi,

What base or numbering system does Warcraft 3 use for numbering/ordering object ids (in particular custom made object ids)?

For example I notice that 'B001' is considered less than 'B000' and likewise 'B005' is apparently less than 'B003.' So how are these ordered?

They order them by increasing the last value.

This 'B001' is not less than this 'B000'

But you have to watch when doing something with the order as JNGP can use any unused 4 digit ASCII value as the new Raw Data values.

Alright so if I set an object to 'B001', should not the id for a newly generated object immediately after that be 'B002' ? And I'm guessing it goes 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ ?

So something like base-36?

its base 256.

This is the WurstScript package that is used to convert object ids:

https://github.com/peq/WurstScript/blob/master/Wurstpack/wurstscript/lib/objediting/ObjectIds.wurst

Check the function "idInteger2IdString" which can for example convert 'hfoo' to "hfoo" (int to string).

Btw, these things work too:
'A000' + 5 == 'A005'

the formula is veeery simple:

Take ascii value of all 4 chars, ascii1, ascii2, ascii3, ascii4

Result = (((((ascii1 * 256) + ascii2) * 256) + ascii3) * 256) + ascii4

and yes it uses base 256, so it goes through whole ascii list

note: if you use JNGP, never put /* or */ into rawcodes, because JNGP doesnt like 'a/*b'
