One of the movement events, calcFlySpeed is used when calculating movement speeds when levitating or otherwise flying.

The movement event flow is described below:

--- @param e calcFlySpeedEventData
local function calcFlySpeedCallback(e)
event.register(tes3.event.calcFlySpeed, calcFlySpeedCallback)


An event can be claimed by setting e.claim to true, or by returning false from the callback. Claiming the event prevents any lower priority callbacks from being called.
