Halo

Warning

Version 1.1.1 of the mod includes a breaking change!!! Loading an old save after updating will cause all entity halo NBT data to be lost, and this data can NOT be recovered!!!
Please back up your data and proceed with caution before updating!

Description

Inspired by the iconic halos from Blue Archive.

Some of the BA halos displayed in the gallery must be obtained here.

Halo adds configurable floating halos above entity heads. Each halo is defined by a JSON file and can stack multiple textured layers with independent position, rotation, scale, and glowing settings. A flexible animation system drives per-layer motion via sine, cosine, and linear terms on any axis, from subtle idle bobbing to staggered clock-ring rotation.

YSM Compatible

YSM compatibility is currently undergoing testing; you may encounter graphical glitches.

This feature is disabled by default. To enable it, navigate to the game instance’s root directory, locate ./config/halo-azusake/halo_mod_config.json, open it in a text editor, and set the experimentalYsmAnchorEnabled field to true. A restart is required for the changes to take effect.

If the halo appears positioned too high or too low, adjust the experimentalYsmHeadLocalOffset field in the same file. The three parameters correspond to [x, y, z], representing displacement to the right, upward, and backward, respectively.

Usage

• Use /halo show <entity selector> <halo definition> to show halo above target entity
• Use /halo hide <entity selector> to hide its halo
• Use /halo list to list halo loaded
• Other command are used for debug

Features

• Multi-layer halos — stack multiple layers with per-layer transform and glowing toggle
• Per-layer animation — sin, cos, and linear function terms on any offset or rotation axis; multiple terms on the same axis are summed
• Orientation modes — locked (follows entity yaw), free (floats loose), sync (hybrid)
• Data-driven — all definitions are JSON files under data/halo/halo_definitions/; compatible with data packs and resource packs
• Ingame commands — /halo for real-time preview and management

Built-in definitions

• ring_default — a 7-layer clock-ring design
• hud — a hud like design

Compatibility
