The '''EVNT format''' is a companion to [[ANIM (File Format)|ANIM]] resources.
The '''EVNT format''' is a companion to [[ANIM (File Format)|ANIM]] resources. It controls functional events synchronized to rigged animations for things like sound effects, visual effects, character messages, and playback control. In Echoes, this format was merged in to the end of the [[ANCS (File Format)|ANCS]] format, but the structure of the file is mostly the same (with a couple changes).
Animators are able to synchronize functional events to rigged animations for things like sound effects, visual effects, character messages, and playback control.

This file format is almost completely documented
Some event parameters need research

The EVNT format is a companion to ANIM resources. It controls functional events synchronized to rigged animations for things like sound effects, visual effects, character messages, and playback control. In Echoes, this format was merged in to the end of the ANCS format, but the structure of the file is mostly the same (with a couple changes).

Format

Type Count Name Notes
u32 1 Version Either 1 or 2. Both can appear in Prime 1, while Echoes uses version 2 (the version number wasn't updated in Echoes despite format changes).
u32 1 Loop Event Count

u32 1 UEVT Event Count
