Game Frozen or Stuck?
|
|
=====================
|
|
|
|
Infinite Loop in NetscriptJS
|
|
----------------------------
|
|
|
|
If your game is frozen or stuck in any way, then the most likely culprit is an
|
|
infinitely running loop in :ref:`netscriptjs`. To get past the freezing, run the game with
|
|
`?noScripts` in the URL:
|
|
|
|
`https://bitburner-official.github.io/bitburner/?noScripts <https://bitburner-official.github.io/bitburner/?noScripts>`_
|
|
|
|
Then, to fix your script, make sure you have a sleep or any other timed function like `hack()` or
|
|
`grow()` in any infinite loops::
|
|
|
|
while(true) {
|
|
// This is an infinite loop that does something
|
|
...
|
|
await ns.sleep(1000); // Add a 1s sleep to prevent freezing
|
|
}
|
|
|
|
Also make sure that each while loop gets to `awaited` function or `break`, for example the next snippet has a sleep
|
|
function, but it nor any possible conditional breaks are never reached and therefore will crash the game::
|
|
|
|
while(true) {
|
|
let currentMoney = ns.getServerMoneyAvailable("n00dles");
|
|
let maxMoney = ns.getServerMaxMoney("n00dles");
|
|
if (currentMoney < maxMoney/2){
|
|
await ns.grow("n00dles");
|
|
}
|
|
if (currentMoney === maxMoney){
|
|
break;
|
|
}
|
|
}
|
|
|
|
If `n00dles` current money is, for example, 75% of the maximum money, the script will not reach neither `grow` nor `break` and crashes the game.
|
|
Adding a sleep like in the first example, or changing the code so that `awaited` function or `break` is always reached, would prevent the crash.
|
|
|
|
Common infinite loop when translating the server purchasing script in starting guide to :ref:`netscriptjs` is to have a
|
|
while loop, that's condition's change is conditional::
|
|
|
|
var ram = 8;
|
|
var i = 0;
|
|
|
|
while (i < ns.getPurchasedServerLimit()) {
|
|
if (ns.getServerMoneyAvailable("home") > ns.getPurchasedServerCost(ram)) {
|
|
var hostname = ns.purchaseServer("pserv-" + i, ram);
|
|
ns.scp("early-hack-template.script", hostname);
|
|
ns.exec("early-hack-template.script", hostname, 3);
|
|
++i;
|
|
}
|
|
}
|
|
|
|
if player does not currently have enough money to purchase a server, the `if`'s condition will be false and `++i` will not be reached.
|
|
Since the script doesn't have `sleep` and value `i` will not change without the `if` being true, this will crash the game. Adding a `sleep`
|
|
that is always reached would prevent the crash.
|
|
|
|
Blackscreen
|
|
-----------
|
|
|
|
If the game window becomes a black screen without the game itself crashing, this is caused by
|
|
the game running too many concurrent scripts (the game runs on a browser and each tab can only
|
|
use so much ram until it crashes). Depending on which scripts are running and your hardware,
|
|
this number can vary between 50000 to 100000 instances (in version 2.0.2. In prior versions this number
|
|
was about 1/5th of that). To prevent this from happening make sure to :ref:`multithread<gameplay_scripts_multithreadingscripts>`
|
|
the scripts as much as possible.

Bug
|
|
---
|
|
|
|
Otherwise, the game is probably frozen/stuck due to a bug. To report a bug, follow
|
|
the guidelines `here <https://github.com/bitburner-official/bitburner-src/blob/master/doc/CONTRIBUTING.md#reporting-bugs>`_.
