Note:

The specification uses A to represent an arbitrary anim instance in property and function definitions.

A.id -> string

Description:

The identification code of an animation. This code should be unique among all the animations of a style. Animation IDs mustn't contain hyphens (-), as this would break the parsing of sprite IDs.

A.get_frame_count() -> int

Returns the number of frames in the animation.

Note:

An animation with a four-frame cycle, but only three visually unique frames (e.g. walk: step 1, middle, step 2) will return 3 instead of 4 if it is defined as an oscillating (ping-pong) animation rather than a looping animation.

anim constructor:

• $Init::anim
