Pivoting Component is a simple script to rotate/pivot a non-spinning prim in place, such as boat rudder or car steering wheel. You could animate those prims to change position/rotation for when steering using Prim Control, but if they only need to rotate in place and not re-position, Pivoting Component may be a simpler option.
Drop it in the prim you wish to have pivot. You will need to pick a number (1-6) at the top of the script to adjust its axis and optionally adjust the degrees it pivots/rotates.
integer DIRECTION = 1; // choose 1-6, try each one until you find the right axis for the prim float DEGREES = 45; // Degrees to pivot/rotate
If it is turning in the wrong direction when you turn, change the DIRECTION value.
