Raw

"war3mapUnits.doo" (The unit and item file)

File format

The file format constists of a header, followed by a data block, followed by a (unused) footer.

Header

Size Description
char[4] file ID = "W3do"
int file version = 8
int subversion? (often set to [0B 00 00 00]h)
int number of units and items defined

Data

Each unit/item is defined by a block of bytes (variable length) organized like this

Size Description
char[4] type ID (iDNR = random item, uDNR = random unit)
int variation
float coordinate X
float coordinate Y
float coordinate Z
float rotation angle
float scale X
float scale Y
float scale Z
byte unknown (maybe flags?)
int player number (owner)
short unknown
int hit points (-1 = use default)
int mana points (-1 = use default, 0 = unit doesn't have mana)
int map item table pointer (for dropped items on death)
if -1 => no item table used
if >= 0 => the item table with this number will be dropped on death
int number "s" of dropped item sets

This is followed by s number of dropped item sets data structure:

Size Description
int number "d" of dropable items

"d" times dropable items structures:

Size Description
char[4] item ID ([00 00 00 00]h = none)
this can also be a random item id (see below)
int % chance to be dropped

Then more data:

Size Description
int gold amount (default = 12500)
float target acquisition range (-1 = normal (500), -2 = camp (200))
int hero level (set to 1 for non hero units and items)
int strength of the hero (0 = use default)
int agility of the hero (0 = use default)
int intelligence of the hero (0 = use default)
int number "n" of items in the inventory
then there is n times a inventory item structure (see below)

Then n number of items in inventory:

Size Description
int inventory slot (this is the actual slot - 1, so 1 => 0)
char[4] item id (as in ItemData.slk) '\0' = none. This can also be a random item id (see below)

Then more data:

Size Description
int number "k" of modified abilities for this unit
then there is k times a ability modification structure (see below)

Then k number of modified abilities:

Size Description
char[4] ability id (as in AbilityData.slk)
int active for autocast abilities, 0 = no, 1 = active
int level for hero abilities

Then random unit/item flag:

Size Description
int random unit/item flag "r"

If r == 0:

Size Description
byte[3] level of the random unit/item,-1 = any (this is actually interpreted as a 24-bit number)
byte byte item class of the random item, 0 = any, 1 = permanent ... (this is 0 for units)

(r is also 0 for non random units/items so we have these 4 bytes anyway (even if the id wasn't uDNR or iDNR))

If r == 1:

Size Description
int unit group ID (defined in w3i)
int position (which column of this group). The column should of course have the item flag set (in the w3i) if this is a random item

If r == 2:

Size Description
int "g" number of entries in custom table

...which is followed by g number of units:

Size Description
char[4] unit ID
int percentual chance of choice

After random item/unit flag block we have:

Size Description
int custom color (-1 = none, 0 = red, 1=blue,...)
int Waygate: active destination number (-1 = deactivated, else it's the creation number of the target rect as in war3map.w3r)
int creation number

Footer

Size Description
int unknown/unused (0)

Flags

May be similar to the war3map.doo flags

Random item ids

random item ids are of the type char[4] where the 1st letter is "Y" and the 3rd letter is "I"

the 2nd letter narrows it down to items of a certain item types

  • "Y" = any type
  • "i" to "o" = item of this type, the letters are in order of the item types in the dropdown box ("i" = charged)

the 4th letter narrows it down to items of a certain level

  • "/" = any level (ASCII 47)
  • "0" ... = specific level (this is ASCII 48 + level, so level 10 will be ":" and level 15 will be "?" and so on)

Random unit ids

random unit ids are of the type char[4] where the 1st three letters are "YYU"

the 4th letter narrows it down to units of a certain level

  • "/" = any level (ASCII 47)
  • "0" ... = specific level (this is ASCII 48 + level, so level 10 will be ":" and level 15 will be "?" and so on)
