Vehicle Animation

This page is a work in progress. Check back at a later date for more up-to-date information.

The vehicle animation resource type stores per-vehicle user-triggered animations, working in conjunction with a Body Part Remap Data resource.

Structures

Note: This type has no available debugging symbols. All structures are based on user research and are unconfirmed.

Animation

Hmmm...

To do: Research the non-primary indices.

Offset	Length	Type	Name	Description	Comments
0x0	0x1	int8_t	?	Animation index	Primary index
0x1	0x1	int8_t	?	Second animation index?	-1 if unused
0x2	0x1	int8_t	?	Third animation index?	-1 if unused

Animation data

Hmmm...

To do: Research types/flags, understand connection between byte at 0x2 and secondary data.

Offset	Length	Type	Name	Description	Comments
0x0	0x1	int8_t	?	Index
0x1	0x1	int8_t	?	Type or flags
0x2	0x1	int8_t	?	Secondary index?	Refers to secondary data index on cops but not others
0x3	0xD			padding
0x10	0x30	Matrix33	?

Secondary data

Hmmm...

To do: Understand the animation type/action field.

Offset	Length	Type	Name	Description	Comments
0x0	0x1	int8_t	?	Index
0x1	0x1	int8_t	?	Animation type/action (per pashok)	Trigger? 0 and 0x15 on cops/DLC. More on bikes (0xB).
0x2	0x1	bool	?	Loop animation
0x3	0xD			padding
0x10	0x20	Vector4[2]	?

Enumerations

Type or flags

Hmmm...

To do: Values such as 3 are used; explore what they do and determine if these are flags or not.

Name	Value	Comments
?	0x1	Rotate
?	0x2	Transform
?	0x4	Rotate (reversed)?
