RAM Usage: 5.7GB This script will fully automate the purchase of all Hacknet upgrades in the fastest method possible. The fastest method is exponential returns awarded through selecting the cheapest upgrade at all times, therefore making your money work for you faster. Determine the cheapest upgrade, wait for funds, purchase, rinse and repeat. Create ES5 Script This script utilises ES5 JavaScript interpreter, otherwise referenced as Netscript 1.0 meaning a file extension of .script is required. While inside the Bitburner Terminal create a new script by typing the following: nano nameOfYourFile.script Example: nano hacknet_infinite.script Note: This script requires 5.7GB of memory available Alternative - Create ES6 Script This script utilises ES6 JavaScript interpreter, otherwise referenced as Netscript 2.0 meaning a file extension of .js is required. This alternative script has been provided by Caladrel While inside the Bitburner Terminal create a new script by typing the following: nano nameOfYourFile.js Example: nano hacknet_infinite.js Note: This script requires 5.7GB of memory available Script Code ES5.script Copy the contents of the script and save into the new script file you just created. // Create Function to Return Balance function myMoney() { return getServerMoneyAvailable("home"); } // Disable Logging for the Following Commands Below (We Dont Want To See Them While we Wait for Our Balance to Grow) disableLog("getServerMoneyAvailable"); disableLog("sleep"); // Create Function to Purchase Upgrade Based on 3 Flags for Node, Item, Qty // # Note Qty is not utilised but the Framework is in Place to Future Proof function purchase(node, item, qty){ var node = node, item = item, qty = qty; if (item == "New Node"){ hacknet.purchaseNode(); print("Purchasing New Node") } if (item == "LVL"){ hacknet.upgradeLevel(node , qty) print("Purchasing LVL Upgrade for Node: " + node) } if (item == "RAM"){ hacknet.upgradeRam(node , qty) print("Purchasing RAM Upgrade for Node: " + node) } if (item == "CPU"){ hacknet.upgradeCore(node , qty) print("Purchasing CPU Upgrade for Node: " + node) } } // Create Function to Find the Cheapest Upgrade and Set Flags to be Used by the Purchase Function // We will set the Default Flags to Purchase a New Node, Only to be Overwritten if a Cheaper Option is Available function check_cheapest() { var new_node_cost = hacknet.getPurchaseNodeCost(); var node = "Default"; var item = "New Node"; var qty = 1; var cheapest = new_node_cost; var node_qty = hacknet.numNodes(); // Iterate Through all Node Upgrade Options, Overwrite Flags if Cheaper Upgrade is Found for (var i = 0; i < node_qty; i++) { var node_lvl = hacknet.getLevelUpgradeCost(i, 1); var node_ram = hacknet.getRamUpgradeCost(i, 1); var node_cpu = hacknet.getCoreUpgradeCost(i, 1); if (node_lvl < cheapest) { cheapest = node_lvl; node = i; item = "LVL"; } if (node_ram < cheapest) { cheapest = node_ram; node = i; item = "RAM"; } if (node_cpu < cheapest) { cheapest = node_cpu; node = i; item = "CPU"; } } // I am not a JavaScript Programmer so I am not Adept at String Manipulation in this Language // Print a Summary Log of Cheapest Upgrade Found // Thanks @Dr. Red print( " n" + "Cheapest Hacknet Upgrade Available:" + " n" + "Node : " + node + " n" + "Item : " + item + " n" + "Qty : " + qty + " n n" + "Current Balance : $" + myMoney() + " n" + "Upgrade Cost : $" + cheapest + " n" ) // After Determining the Cheapest Upgrade we will wait for Balance to Increase Enough to Purchase (This is why we turned off logging) while (myMoney() < cheapest) { print("Waiting for funds to increase") sleep(3000); } // Call the Purchase Function purchase(node, item, qty); } // Run the Cheapest Upgrade Function in an Infinite Loop while(true) { check_cheapest() } Alternative - Script Code ES6.js Copy the contents of the script and save into the new .js file you just created. /** @param {NS} ns **/ export async function main(ns) { while(true) { // Check optimal purchase var nodeNum = "Default"; var itemType = "New Node"; var cheapest = ns.hacknet.getPurchaseNodeCost(); var num_nodes = ns.hacknet.numNodes(); // Iterate through all nodes and select lowest purchase/upgrade available for (var i = 0; i < num_nodes; i++) { var level_cost = ns.hacknet.getLevelUpgradeCost(i, 1); var ram_cost = ns.hacknet.getRamUpgradeCost(i, 1); var cpu_cost = ns.hacknet.getCoreUpgradeCost(i, 1); if (level_cost < cheapest) { cheapest = level_cost; nodeNum = i; itemType = "Level"; } if (ram_cost < cheapest) { cheapest = ram_cost; nodeNum = i; itemType = "RAM"; } if (cpu_cost < cheapest) { cheapest = cpu_cost; nodeNum = i; itemType = "CPU"; } } // If affordable, purchase and recalculate above var purchased = false; while (!purchased) { var money = ns.getServerMoneyAvailable("home"); if (money >= cheapest) { if (itemType == "New Node"){ ns.hacknet.purchaseNode(); } if (itemType == "Level"){ ns.hacknet.upgradeLevel(nodeNum , 1); } if (itemType == "RAM"){ ns.hacknet.upgradeRam(nodeNum , 1); } if (itemType == "CPU"){ ns.hacknet.upgradeCore(nodeNum , 1); } purchased = true; } // If we didn't purchase, wait 1 second and try again if(!purchased) { await ns.sleep(1000); } } } } Usage After saving the script you can run it by typing: run nameOfYourScript.script Example: run hacknet_infinity.script Alternatively if you went for the ES6 option run your code by typing: run nameOfYourScript.js Example: run hacknet_infinity.js Under the Hood This script iterates through all upgrade options, sets flags for the cheapest option and waits until there is enough funds to purchase. Currently it does not utilise the quantity function, as the cheapest option is always to purchase in single units to get your money working for you faster under the passive income method. This is why the variable Qty is set to 1 and not overwritten in the loop. If you read through the Hacknet API on the official website there is an example script which uses a value of 10 when purchasing basic levels for Nodes. IMO buying single units will net you more money in the long run due to exponential returns from the smaller purchases of single levels. Please see below screen shots below to see how IMBA this script is to your crash flow.
