Bas

bas files each represent an animation that can be called by an actor or cutscene. They contain a reference to an animation name, but not the animation file itself. They can be found at Actor/AS/{EventName}/{AnimationSequenceName}.bas in beventpacks and TitleBG.pack/Actor/AS, and Actor/AS/{AnimationSequenceName}.bas in bactorpacks.

Layout

Each bas file is made up of one list of elements, named Elements. Each element (Element0, Element1, etc) can be either a test to figure out what animation to play, or a call to play the animation.

Parameters

All nodes have Parameters, which determine what kind of node they are. They can be a control node, which helps decide which animation to play, or an animation node, which actually plays the animation.

Children

Control nodes will have Children, in addition to Parameters, which determine which Element to go to after the control node is evaluated. The properties of Children will be named Child0, Child1, etc, and each will have a single integer value, which will correspond to the Element number. e.g. Child0: 7 points to Element7.

Extend

All nodes have an Extend, which contains specific details about the node. Control node Extends will contain details about the comparison being performed, while animation nodes will contain information about the animation being played, such as: during which frames of the animation a weapon will deal damage if it hits something, when user input is ignored, when to draw weapon trails through the air for attack animations, etc.

Typed Array

A list of variables of a given type to use for various control comparisons. Corresponds directly to the Children of the node. i.e. if Value0 matches the value being compared against, the code will jump to the Element listed under Child0. If no comparison of a lower Child number has evaluated as true, automatically evaluates a Child whose value is "default" as true.

BitIndex

Used with Parameter TypeIndex 7. Also has TypeIndex, which are used to perform the check.

• 2 - Unknown (believed to check if Link has any armor equipped)
• 30 - Whether or not Link has a shield equipped.
• 33 - Unknown
• 37 - Whether IsBlunt is set to true in the equipped weapon’s bgparamlist
• 46 - Unknown (believed to check if Link is crouched)

Ranges

Used with control nodes that perform a Range evaluation. If the value being compared is above the Start value and below the End value, evaluates as true. Otherwise, moves on to the next value. (Unknown what happens if none of the Ranges evaluate to true, presumably game crash)

FrameCtrl

Used with animation nodes. The node itself is required, even if it is empty (i.e. none of the keys are specified)

Key	Type	Description	Default value
Rate	float	Speed at which to play the animation. Higher numbers are faster.	1.0
EndFrame	int	-	-

TriggerEvents

Used with Parameter TypeIndex 67. Possibly used with other animation node TypeIndexes, but none have so far been observed. Events which are triggered during this animation.

Key	Type	Description	Default value
TypeIndex	int	Which type of event to fire. Known events are detailed below	-
Frame	int	Which frame to fire the event on, relative to the frame numbers of the animation. Can be negative.	-
Value	strRef	-	-

Known TypeIndex values:

• 0 - Unknown (believed to define when an attack begins to deal damage)
• 4 - Triggers the animation controller to transition back into the idle stance. The Frame value should be a few before the end of the actual animation, so that the controller can make the blending look natural.
• 7 - Call AS. Passes the strRef to the ASList to retrieve an AS file and starts evaluating it from Element0.
• 28 - Play audio. Only observed with PV%03d as the value, which corresponds to bfwav files in PlayerVoice.bars, but is believed to be able to play other audio files as well.

HoldEvents

Used with Parameter TypeIndex 67. Possibly used with other animation node TypeIndexes, but none have so far been observed. States that are entered into while the animation is playing.

Key	Type	Description	Default value
TypeIndex	int	Which type of event to fire. Known events are detailed below	-
StartFrame	int	Which frame to start the event on, relative to the frame numbers of the animation. Unknown if it can be negative.	-
EndFrame	int	Which frame to end the event on, relative to the frame numbers of the animation. A value of -1 is treated as the ending frame of the animation.	-
Value	strRef	-	-

Known TypeIndex values:

• 0 - Unknown
• 2 - Unknown
• 3 - Defines when an attack will deal damage. Value is the damage type. Left: slashing. Stab: piercing. Lower: blunt. ^[check]
• 17 - Unknown
• 25 - Unknown
• 45 - Defines when to accept input to start the next attack.
• 48 - Defines when to display the trails in the air during an attack.
