One of the movement events, calcSwimRunSpeed is used when calculating the movement speed while in water when running.

The movement event flow is described below:

--- @param e calcSwimRunSpeedEventData
local function calcSwimRunSpeedCallback(e)
event.register(tes3.event.calcSwimRunSpeed, calcSwimRunSpeedCallback)


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.
