Bonus ID map

This map is derived from bonus_metadata_init, which builds the bonus metadata table at bonus_meta_label. The entry index is the bonus type id used by bonus_apply and bonus_spawn_at.

Table fields:

  • icon_id comes from bonus_meta_icon_id + id * 0x14, used by bonus_render to select the icon sprite.
  • icon_frame maps icon_id to bonuses.png grid=4 frames in artifacts/atlas/frames/game/bonuses/grid4/frame_{icon_id:03d}.png (when icon_id >= 0). Bonus id 3 uses icon_id = -1 and renders the weapon icon from ui_weapon_icons_texture.
  • description comes from bonus_meta_description + id * 0x14, used for the bonus info strings.
  • default_amount comes from bonus_meta_default_amount + id * 0x14, used when bonus_spawn_at is called with duration_override == -1.
  • enabled comes from bonus_meta_enabled + id * 0x14; id 0 is cleared during init.
