Super Simple Vehicle System - Enhanced

[DerVVulfman]

BUMP

to version 10.8

The system now has been altered to handle some issues where the player exits the vehicle HQ and returns to flying/driving/riding a vehicle, only to find out that the vehicle's custom music did not exist.  And after that, disembarking the vehicle did not return the music from the field map.

A series of changes were made to the engine to keep track of the fieldmap music for the latter, and a very simple change to a method within Game_Map was made to fix the former.

However, not everything is perfect.  If the player returns from the Vehicle Headquarters to a vehicle that does not have a set background music piece, no music sounds. Technically, it should instead play the fieldmap's own music. But the music reset system currently employs itself before the map has as yet changed.  So for now, one can simply apply the Change Background Music event command when using the command that returns you to the vehicle.

Meanwhile, the instructions now includes a new section, one to cover script calls.  A fair number of these were inspired by Habs11 during his request to allow scripted transfers to and from vehicles and headquarters back in 2010. However, the instructions never included these.  Clearly an oversight, they have now been included.
