One of the movement events, calcWalkSpeed is used when calculating the base walk speed. Nearly every other movement speed event starts with this, with the exception of calcFlySpeed.

The movement event flow is described below:

--- @param e calcWalkSpeedEventData
local function calcWalkSpeedCallback(e)
event.register(tes3.event.calcWalkSpeed, calcWalkSpeedCallback)


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.
