Cabal Common Library Doc OXPStrength

Overview

This is the main class for the OXPStrength with its members and part of the Cabal_Common_Library.

It is a helper tool specially for mission OXPs to check the environment and helps to determine the players strength. The script is meant for OXP developers only.

The underlaying API calculates a checksum (coef) for entities. This checksum can be gathered by scripts for specific entities (Player and NPCs). Factors are:

• Accuracy (v1.7.1)
• Distance to the hotspots (MainStation,WP and lanes WP,WS,PS)
• Equipment
• Escorts / Defense ships
• Laser
• Mass (v1.7.1)
• MaxEnergy
• MaxPitch (v1.7.1)
• MaxRoll (v1.7.1)
• MaxSpeed
• MaxThrust
• Missiles
• PrimaryRole
• ShieldRechargeRates
• Subent laser
• Turrets

Functions

All profiled times are only for gathering infos for a fully equipped player ship.

checkPower()

	worldScripts.Cabal_Common_OXPStrength.checkOXPStrength.checkPower( entity, logging, coef, location );

Profiler
Native	0.001295s
Extension	0.000488s
JS	0.000807s

Checks entities and returns the gathered coefficient. This is the main entry point for OXPs.

For NPCs the standard range is <500, but OXP entities can have a lot higher value based on their settings. A standard Cobra MkIII has a value of ~100 in the beginning and gets up to >500 if fully equipped with standard weaponry, missiles and other standard equipment. The Boa Class Cruiser has even a bit more.

• See checkSpaceLane(), Table of Player Ships.

Parameters:

entity

Entity. If specified only this entity will be checked, otherwise all entities in the system (except the player).

Optional.

logging

Boolean. If true a verbose list will be logged to Latest.log. This is useful while writing OXPs.

Optional.

coef

Number. If specified the minimum threshold for returned coef. Unused if entity is specified.

Optional. Default 400.

location

Number - Bitmask. If used distance calculations are based on set bits.

Optional. Default 7.

Values:

• 1 - Main Station, default
• 2 - Witchpoint, default
• 4 - Lane W->P, default
• 8 - Lane P->S
• 16 - Lane W->S

Returns:

coef

Number. Calculated coefficient.

If entity was specified the value for this specific entity, otherwise the highest value in the system.

Parameters:

entity

Entity.

Returns:

value

Number. Summed value for all mounted pylons.

Every pylon mounted missile or mine adds based on tokens

• 5 - naval, boost, military, cascade
• 4 - harpoon, intercept, nuke, law, frag, bomb
• 3 - mine, stun, override, jammer, drone, guard, field
• 2 - hard, ecm, rack, launcher, ams

• See checkPower().

Parameters:

entity

Entity.

location

Number.

Optional.

Returns:

array

Array with the format [ID,distMS,distWP,distLWP,distLPS,distLWS]. Distances >50000 will be -1.

ID is

• -2 - Nova system
• -1 - Interstellar space
• 0 - standard system
• 1 - interstellar space, entities close to [0,0,0]
• 2 - standard system, entities close to checked locations

checkWeapons()

	worldScripts.Cabal_Common_OXPStrength.checkOXPStrength.checkWeapons(entity);

Profiler
Native	0.000176s
Extension	0.000067s
JS	0.000152s

Returns array with values for weapons in standard weapon slots (forward, aft, port, starboard).

Parameters:

entity

Entity.

Returns:

array

Array with the format [number of slots, sum, typestring]. typestring is concatenated string of sum (e.g. "5311").

sum is the sum of all weapons

• 1 - Pulse Laser
• 3 - Beam Laser
• 4 - Mining Laser, Twin Plasma Cannon
• 5 - Military Laser
• 8 - Thargoid Laser

checkSubWeapons()

	worldScripts.Cabal_Common_OXPStrength.checkOXPStrength.checkSubWeapons( entity );

Profiler
Native	0.000180s
Extension	0.000077s
JS	0.000132s

Returns array with values for weapons in subEntites.

Parameters:

entity

Entity.

Returns:

array

Array with the format [Number of Turrets, Number of slots, sum, typestring]. typestring is concatenated string of sum, but exclusive turrets (e.g. "1111").

• See checkWeapons()

Properties

CCL_OXPStrength

The script can set a property to be used for strong entities.

	worldScripts.Cabal_Common_OXPStrength.CCL_OXPStrength = 5;

Main purpose is to prevent the spawning by the populator. OXPs can use it in condition scripts. Default is 9.

Suggested classes:

• 1 = coef < 300
• 2 = coef < 400 - This is the default threshold for entities if logging is used.
• 3 = coef < 600
• 4 = coef < 800
• 5 = coef < 1000
• 6 = coef < 1500
• 7 = coef < 3000
• 8 = coef < 5000
• 9 = otherwise, default setting for CCL_OXPStrength.

scriptInfo

ccl_missionShip

Missionships can also use a script_info key to indicate that this entity has to be handled with care by other scripts.

	script_info = {ccl_missionShip = true;}

Table of Player Ships

A short overview about the values for native Oolite player-ships if fully equipped. OXP equipment and weaponry may add to the values and changed native ships (like in replacement sets) may change these values as well. The table is meant as rough orientation if OXPs want to base decisions on players strength.
