Taken from the Pavilion:

There was a post at Doan's old board that showed a somewhat hack, but it wasn't clean in that it required a button press to update. This one constantly checks.

This requires Nash's movement script, and another infinite loop script. Here they are:

[Nash's vehicle script]
Script Branch: Repeat: Flag [off(fixed)] Off
--Other: Vehicle: Deploy Model(invisible object) type=land, speed=normal
--Other: Vehicle: Control Vehicle
Script: Branch End


**make/name 2 variables as Temp X and Temp Y. I used Sample 100 and 101. Next name one flag as 'Moving?'**

[Run/Walk Check]
Script Branch: Repeat: Flag [Off(fixed)] Off
--Data:Game Info: Load
--Data: Variable: Temp X = Party X
--Data: Variable: Temp Y = Party Y
--Other: Wait: 8f
--Data: Game Info: Load
--Script Branch: Condition: Variable [Party X] = [Temp X] + [0]
----Script Branch: Condition: Variable [Party Y] = [Temp Y] + [0]
------Script Branch: Condition: Flag: Moving? = On
--------Flag: [Moving?] = off
--------Member: Effect: [Virk] Motion Change Wait Speed = 100
------end
----end
--end
--Script Branch: Condition: [Party Y] =/= [Temp Y]
----Script Branch: Condition: [Moving?] = Off
------Flag: [Moving?] = On
------Member: Effect: [Virk] Motion Change Walk Speed = 100
----end
--end
--Script Branch: Condition: [Party X] =/= [Temp X]
----Script Branch: Condition: [Moving?] = Off
------Flag: [Moving?] = On
------Member: Effect: [Virk] Motion Change Walk Speed = 100
----end
--end
End Repeat

Next, we need to make an enter map script that applys the above 2 together:


[Enter Map]
Script Control: Apply Together
Script: Call[Vehicle Script]
Script: Call[Run/Walk Check]
Script Control: Apply In Order



finally, make an event named Enter Map, and register that into your world under World Org -> Enter Map Script.

This basically forces the player into a vehicle at all times. This is required because you NORMALLY can't modify the party and have things happen around you. It usually can only be done by triggering events by talking/examining/walking on top of them. This dodges it.
