Revision as of 20:17, 21 May 2010 by Eric Walch (talk | contribs) (Added info about cargo handling in flight.)

Prototype: Object

This class was added in Oolite test release 1.74.

Manifest provides direct access to the cargo carried by the player.

Properties

food

food : Integer (read/write)

Quantity of food in the players ship.

Awarding the player with extra 10 tons of food can be done in different ways:

Manifest.food += 10;
or
player.ship.manifest.food += 10;
or
Manifest["food"] += 10;

If there were less than 10 tons of cargo space available, any extra cargo is silently discarded. A script should therefor first check the cargoSpaceAvailable.

textiles

textiles : Integer (read/write)

Quantity of textiles in the players ship.

radioactives

radioactives : Integer (read/write)

Quantity of radioactives in the players ship.

slaves

slaves : Integer (read/write)

Quantity of slaves in the players ship.

"liquor/wines"

liquor/wines (or liquorWines): Integer (read/write)

Quantity of liquor/wines in the players ship.
Access the liquor/wines quantity on the hold via either

Manifest["liquor/wines"]
or
Manifest.liquorWines

luxuries

luxuries : Integer (read/write)

Quantity of luxuries in the players ship.

narcotics

narcotics : Integer (read/write)

Quantity of narcotics in the players ship.

computers

computers : Integer (read/write)

Quantity of computers in the players ship.

alloys

alloys : Integer (read/write)

Quantity of alloys in the players ship.

firearms

firearms : Integer (read/write)

Quantity of firearms in the players ship.

furs

furs : Integer (read/write)

Quantity of furs in the players ship.

minerals

minerals : Integer (read/write)

Quantity of minerals in the players ship.

gold

gold : Integer (read/write)

Quantity of gold in the players ship. 500 kg and more counts as 1 ton, below 500 kg counts as 0 ton in cargoSpace calculations. Therefor a script can only add up to 499 kg of gold into a filled hold. (The player himself can buy unlimited quantities at the market screen.)

platinum

platinum : Integer (read/write)

Quantity of platinum in the players ship. 500 kg and more counts as 1 ton in cargoSpace calculations.

"gem-stones"

gem-stones (or gemStones): Integer (read/write)

Quantity of gem-stones in the players ship. 500000 g and more counts as 1 ton in cargoSpace calculations.
Access to the gem-stones property is via

Manifest["gem-stones"]
or
Manifest.gemStones

"alien items"

alien items (alternative name alienItems): Integer (read/write)

Quantity of alien items in the players ship.
Access the alien items property either via

Manifest["alien items"]
or
Manifest.alienItems

list

list : Array (read-only)

Array of objects. Each object contains the info for a commodity present in the player's hold:

commodity : String (corresponds to manifest["commodity"])
quantity : Integer
displayName : String (commodity display name, can be different for different languages)
unit : String ('t' = tons, 'kg' = kilograms, 'g' = grams)

Example usages of the manifest.list property

var i, m;

// for certain types of cargo (like gem-stones) player.ship.cargoSpaceUsed can still be 0
// even if we're carrying 100 or more.
log('The player is currently carrying ' + (manifest.list.length > 0 ?'the following:' : 'nothing.'))

for (i = 0; i<manifest.list.length;i++)
{
  m = manifest.list[i];
  log( m.quantity + m.unit + ' of '+ m.displayName );
}

and

var i, c;

// now remove at least 1 of / 20% of each type of cargo carried.
for (i = 0; i<manifest.list.length;i++)
{
	c = manifest.list[i].commodity;
	manifest[c] = Math.floor(manifest[c] * .8);
}

Additional info

When a player launches, all cargo from the manifest is loaded in cargo pods with role: "1t-cargopod". This has some consequences for handling kg and gram commodities when in flight:

- Every full ton of such an article that the player has, is put in a barrel on launch and consumes 1 ton cargo space.
- Every barrel that the player scoops takes one ton of cargo space even when the content is far less in weight.
- Every time cargo is added by script, the added amount is added in an one ton barrel to the hold. (a barrel with role: "1t-cargopod")
- Every time the cargo is reduced, it is removed from one of the barrels. When the barrel becomes empty in the process, the barrel is removed.

On docking all barrels are unloaded and the Manifest becomes just a list of goods. The Manifest can be handled the same way when docked as when in flight but above cargo handling might explain why the hold fills up fast when adding several small quantities of kg/gram commodities by script.
Nothing new actually as the addition per container when in flight already happened this way with the legacy scripts.
