// Package d2animdata provides a file parser for AnimData files. AnimData files have the '.d2'
|
|
// file extension, but we do not call this package `d2d2` because multiple file types share this
|
|
// extension, and because the project namespace prefix makes it sound terrible.

package d2animdata

/*
|
|
The AnimData.d2 file is a binary file that contains speed and event data for animations.
|
|
|
|
The data is encoded as little-endian binary data
|
|
|
|
The file contents look like this:
|
|
|
|
type animData struct {
|
|
blocks [256]struct{
|
|
recordCount uint8
|
|
records []struct{ // *see note below
|
|
name [8]byte // last byte is always \0
|
|
framesPerDirection uint32
|
|
speed uint16 // **see note below
|
|
_ uint16 // just padded 0's
|
|
events [144]uint8 // ***see not below
|
|
}
|
|
}
|
|
}
|
|
|
|
*NOTE: can contain 0 to 67 records
|
|
|
|
**NOTE: game fps is assumed to be 25, the speed is calculated as (25 * record.speed / 256)
|
|
|
|
**NOTE: Animation events can be one of `None`, `Attack`, `Missile`, `Sound`, or `Skill`
