Wings

Wing items go in the Curios wings slot (put the item in the item tag #curios:wings). Holding jump in the air rises for the flight time, then glides; landing refills it. No fall damage while flying or gliding.

File: data/<ns>/fundamentum/wings/<name>.json, keyed by item. Every field is optional.

{
  "item": "mymod:angel_wings",
  "flight_ticks": 50,
  "rise_speed": 0.45,
  "rise_acceleration": 0.12,
  "horizontal_speed": 1.25,
  "glide_fall_speed": 0.12
}

Field	Default	Meaning
item	the file id	the wing item
flight_ticks	40	how long you can rise, in ticks; scaled by the fundamentum:wing_flight_time attribute and capped at 75 (a dedicated server kicks "flying" players after 80)
rise_speed	0.4	top rising speed, blocks per tick
rise_acceleration	0.1	how fast you reach it
horizontal_speed	1.0	multiplier on air movement
glide_fall_speed	0.15	fall speed while gliding, at least 0.04

A wing item that isn't in any file uses the defaults.

Drawing the wings

On 26.1.2, a wing item with an equippable component naming an equipment asset is drawn on the player from that asset's wings layer, like an elytra. Otherwise (and always on 1.21.1) the mod that adds the wings draws them.
