Creature animations are stored in BAM files. There are usually a series of BAM files for each animation, e.g. an attacking animation, a walking animation. These way in which these animations are split across the sequences in BAM files, and across BAM files themselves, depends on which animation scheme the creature animation uses.
There are several creature animation schemes. The list below is presented as a rough guide.

• IWD style
• BG1 character style
• BG1 monster style
• PST style
• BG/IWD style
• Character animations

---

IWD style
One optional weapon letter for weapon overlays
Actions:

Convention:
Example: The armored skeleton animation MSKAAGU.BAM (battle axe, Get Up), MSKAMA1.BAM (morning star, attack-slash).

---

BG1 character style
These animations have [E] files for eastern orientations. There are only 8 orientations of which 5 are in the first file, 3 are in the second file. Both files have the full 8 orientation slots, but only 5/3 are useful.

Convention:
Example: The sirine animation MSIRG1.BAM (unarmed/creature, "left" animation), MSIRBG1E.BAM (bow, "right" animation).

---

BG1 monster style
These have no secondary files for mirrors. There are 9 orientations for each action, the 7 eastern orientations are generated. All animations are 'G<number>'
Actions:

Convention: Example: The rakshasa animation MRAKG2.BAM (unarmed/creature), MRAKG2CB.BAM (crossbow).

There are also minor sub-types for birds/cow/carrion crawler/dragons etc.

---

PST style
Similar to the IWD style, there is a separate file for each action.
Actions:
Some animations are missing SC sequences, these animations look relaxed even in combat (e.g. Morte).
Some animations are missing SD sequences, these animations seem always agitated (e.g. Nupperibo).
Some animations have special cycles (e.g. Fidgets).

Convention:

---

BG2/IWD style
These animations have no [E] files for eastern orientations. There are 9 orientations for each action, the 7 eastern orientations are generated by code. Melee animations are 'A<number>', CA-cast, 'SX'-xbow shot, 'SS'-sling, 'SA'-bow. Weapon overlays are in separate files.

Convention:

---

Character
Character animation BAMS use a standard naming system. Each BAM is given an 7 character filename, corresponding to the contents of the BAM. This system is described below.

Character 1	Character 2	Character 3	Character 4	Character 5	Character 6	Character 7
Irrelevant	Race	Gender	Class	Armor	Action	Detail
	D: Dwarf/Gnome H: Human E: (Half) Elf I: Halfling O : Half-Orc	F: Female M: Male	C: Cleric F: Fighter/Ranger/Paladin M: Monk T: Thief/Bard W: Mage B: ?	1: None 2: Leather 3: Robe 4: Platemail/Mail	A: Attack C: Cast G: Misc. S: Shooting W: Walking	Char 6 = A 1: 1-handed overhead 2: 2-handed overhead 3: 1-handed backslash 4: 2-handed backslash 5: 1-handed thrust 6: 2-handed thrust Char 6 = S <empty> = bow x: crossbow

If there is an E in the end of the file, it means that it's the missing part of the file without an E.

Example: CIMT1CA:

Example: CHMF4A5 :



Weapon
Weapon animations are named in the following format: WxsAAnn
W = All weapons animations begin with W
x = Unknown, player or monster?
s = Size (S = small, M = Medium, L = Large, H = Huge)
AA = Item name (as in the itm header animation field)
nn = Action (as sequence field, above)





PLT Files
The paperdoll image (PLT file) for an animation is named after the animation name (anisnd.ids), a number represending the armor state, then 'inv', hence mber1inv for a bear paperdoll.
