Netscript Bladeburner API¶

Netscript provides the following API for interacting with the game's Bladeburner mechanic.

The Bladeburner API is not immediately available to the palyer and must be unlocked later in the game

WARNING: This page contains spoilers for the game

The Bladeburner API is unlocked in BitNode-7. If you are in BitNode-7, you will automatically gain access to this API. Otherwise, you must have Source-File 7 in order to use this API in other BitNodes

Bladeburner API functions must be accessed through the bladeburner namespace

In Netscript 1.0:

bladeburner.getContractNames();
bladeburner.startAction("general", "Training");

In NetscriptJS (Netscript 2.0):

ns.bladeburner.getContractNames();
ns.bladeburner.startAction("general", "Training");

Bladeburner Action Types¶

Several functions in the Bladeburner API require you to specify an action using its type and name. The following are valid values when specifying the action's type:

Contracts

contract
contracts
contr

Operations

operation
operations
op
ops

Black Ops

blackoperation
black operation
black operations
black op
black ops
blackop
blackops

General Actions (Training, Field Analysis, Recruitment)

general
general action
gen

getContractNames¶

getContractNames()¶: Returns an array of strings containing the names of all Bladeburner contracts

getOperationNames¶

getOperationNames()¶: Returns an array of strings containing the names of all Bladeburner operations

getBlackOpNames¶

getBlackOpNames()¶: Returns an array of strings containing the names of all Bladeburner Black Ops

getGeneralActionNames¶

getGeneralActionNames()¶: Returns an array of strings containing the names of all general Bladeburner actions

getSkillNames¶

getSkillNames()¶: Returns an array of strings containing the names of all Bladeburner skills

startAction¶

startAction(type, name)¶

Arguments:	type (string) -- Type of action. See Bladeburner Action Types name (string) -- Name of action. Must be an exact match

Attempts to start the specified Bladeburner action. Returns true if the action was started successfully, and false otherwise.

stopBladeburnerAction¶

stopBladeburnerAction()¶: Stops the current Bladeburner action

getActionTime¶

getActionTime(type, name)¶

Arguments:	type (string) -- Type of action. See Bladeburner Action Types name (string) -- Name of action. Must be an exact match

Returns the number of seconds it takes to complete the specified action

getActionEstimatedSuccessChance¶

getActionEstimatedSuccessChance(type, name)¶

Arguments:	type (string) -- Type of action. See Bladeburner Action Types name (string) -- Name of action. Must be an exact match

Returns the estimated success chance for the specified action

getActionCountRemaining¶

getActionCountRemaining(type, name)¶

Arguments:	type (string) -- Type of action. See Bladeburner Action Types name (string) -- Name of action. Must be an exact match

Returns the remaining count of the specified action.

Note that this is meant to be used for Contracts and Operations. This function will return 'Infinity' for actions such as Training and Field Analysis.

getRank¶

getRank()¶: Returns the player's Bladeburner Rank

getSkillPoints¶

getSkillPoints()¶: Returns the number of Bladeburner skill points you have

getSkillLevel¶

getSkillLevel(skillName="")¶

Arguments:	skillName (string) -- Optional name of Skill. Empty string by default

If no argument or an empty string is passed in, this function returns an object with your level for all Bladeburner Skills (only for skills that have at least one level). In the object, the name of the Bladeburner Skills are the keys and your skill levels are the values. For example:

{
    "Blade's Intuition":    10,
    "Cloak":                5,
    "Evasive System":       6
}

If the name of a skill is passed in as an argument, then this function returns your level in the specified skill.

The function returns -1 if an invalid skill name is passed in

upgradeSkill¶

upgradeSkill(skillName)¶

Arguments:	skillName (string) -- Name of Skill to be upgraded. Must be an exact match

Attempts to upgrade the specified Bladeburner skill. Returns true if the skill is successfully upgraded, and false otherwise

getTeamSize¶

getTeamSize(type, name)¶

Arguments:	type (string) -- Type of action. See Bladeburner Action Types name (string) -- Name of action. Must be an exact match

Returns the number of Bladeburner team members you have assigned to the specified action.

Setting a team is only applicable for Operations and BlackOps. This function will return 0 for other action types.

setTeamSize¶

setTeamSize(type, name, size)¶

Arguments:	type (string) -- Type of action. See Bladeburner Action Types name (string) -- Name of action. Must be an exact match size (int) -- Number of team members to set. Will be converted using Math.round()

Set the team size for the specified Bladeburner action.

Returns the team size that was set, or -1 if the function failed.

getCityEstimatedPopulation¶

getCityEstimatedPopulation(cityName)¶

Arguments:	cityName (string) -- Name of city. Case-sensitive

Returns the estimated number of Synthoids in the specified city, or -1 if an invalid city was specified.

getCityEstimatedCommunities¶

getCityEstimatedCommunities(cityName)¶

Arguments:	cityName (string) -- Name of city. Case-sensitive

Returns the estimated number of Synthoid communities in the specified city, or -1 if an invalid city was specified.

getCityChaos¶

getCityChaos(cityName)¶

Arguments:	cityName (string) -- Name of city. Case-sensitive

Returns the chaos in the specified city, or -1 if an invalid city was specified

switchCity¶

switchCity(cityName)¶

Arguments:	cityName (string) -- Name of city

Attempts to switch to the specified city (for Bladeburner only).

Returns true if successful, and false otherwise

getStamina¶

getStamina()¶

Returns an array with two elements:

[Current stamina, Max stamina]

Example usage:

function getStaminaPercentage() {
    let res = bladeburner.getStamina();
    return res[0] / res[1];
}

joinBladeburnerFaction¶

joinBladeburnerFaction()¶

Attempts to join the Bladeburner faction.

Returns true if you successfully join the Bladeburner faction, or if you are already a member.

Returns false otherwise.

Examples¶

Basic example usage:

tprint(bladeburner.getContractNames());
tprint(bladeburner.getOperationNames());
tprint(bladeburner.getBlackOpNames());
tprint(bladeburner.getGeneralActionNames());
tprint(bladeburner.getSkillNames());
tprint(bladeburner.getActionTime("contract", "Tracking"));
tprint("Rank: " + bladeburner.getRank());
tprint("Skill Points: " + bladeburner.getSkillPoints());
tprint("Cloak Skill Level: " + bladeburner.getSkillLevel("Cloak"));
tprint("Trying to upgradeSkill: " + bladeburner.upgradeSkill("Cloak"));
tprint("Skill Points remaining: " + bladeburner.getSkillPoints());

tprint("Trying to switch to a nonexistent city: " + bladeburner.switchCity("lskgns"));

tprint("Chongqing chaos: " + bladeburner.getCityChaos(chongqing));
tprint("Chongqing estimated pop: " + bladeburner.getCityEstimatedPopulation(chongqing));
tprint("Chonqging estimated communities: " + bladeburner.getCityEstimatedCommunities(chongqing));

Bladeburner handler example. Note that this avoids the need of using the bladeburner namespace identifier by attaching the Bladeburner API functions to an object:

const FIELD_ANALYSIS_INTERVAL = 10; //Number of minutes between field analysis states
const FIELD_ANALYSIS_DURATION = 5;  //Duration in minutes

function BladeburnerHandler(ns, params) {
    //Netscript environment becomes part of the instance
    this.ns = ns;

    //Netscript bladeburner API becomes part of this instance
    for (var bladeburnerFn in ns.bladeburner) {
        this[bladeburnerFn] = ns.bladeburner[bladeburnerFn];
    }
