Vehicle prototypes are used to spawn stock vehicles. After a vehicle has been spawned, it is saved in a different format.
Vehicle prototypes do not currently accept copy-from

].* Important! *. Vehicle parts must be defined in the same order you would install them in the game (ie, frames and mount points first). You also cannot break the normal rules of installation (you can't stack non-stackable part flags).
The part list contains an arbitrary number of lines. Each line is of the form: { "x": X, "y": Y, "part": PARTID, ... } or { "x": X, "y": Y, "parts": [ PARTID1, ... ] }
In the first form, the line defines a single part at location X,Y of vehicle part type PARTID. It can have the optional "ammo", "ammo_types", "ammo_qty", or "fuel" keys with an appropriate value following.
In the second form, the line defines several parts at location X, Y. Each part is either defined by its PARTID string, or can be an object of the form { "part": PARTID, ... } with any of the optional keys "ammo", "ammo_types", "ammo_qty", or "fuel" as above.
Several different lines can have the same X, Y co-ordinates and each one adds additional parts to that location. Parts must be added in the correct order ie: A wheel hub must be added prior to the wheel, but after the frame.
Some parts can be installed with different symbols (and tileset sprites) in different locations. The different symbols can either be different parts (usually generated with copy-from) or the same part with a "symbols" or "standard_symbols" entry. In the latter case, the different symbols are variants of the part.
If a part has variants, the specific variant can be specified in the vehicle prototype by appending the variant to the part id after a _ symbol. Thus, "frame_cross" is the "cross" variant of the "frame" part.
The items list contains an arbitrary number of lines. Each line is of the form: { "x": X, "y": Y, TYPE: DATA }, and describes the items that may spawn at that location. TYPE and DATA may be one of:
"items": "itemid" // single item of that type
"items": [ "itemid1", "itemid2", ... ] // all the items in the array
"item_groups": "groupid" // one or more items in the group, depending on
// whether the group is a collection or distribution
"item_groups": [ "groupid1", "groupid2" ... ] // one or more items for each groupthe optional keyword "chance" provides an X in 100 chance that a particular item definition will spawn.
If a single item is specified through "items", an itype variant for it can be specified through "variant".
Multiple lines of items may share the same X and Y values.
The zones list contains an arbitrary number of lines. Each line is of the form:
{ "x": X, "y": Y, "type": ZONE_ID }
where ZONE_ID is any valid zone id such as LOOT_UNSORTED.
These zones are only placed if the vehicle has a faction owner.
