IsAiming
From GECK
A function added by the ShowOff NVSE Plugin version 1.65.
Description
Returns 1 if the calling actor reference is aiming or zooming in, 0 otherwise.
In most cases, this is equivalent to checking if the aiming control is being pressed via IsControlPressed, though this function will be future-proofed in case a mod adds a toggle mode to aiming instead of requiring the control to be held.
