IPC possible with TRiBot script and another non-TRiBot program?

Recommended Posts

Is it possible to relay information directly from a script to another Java process? My program consists of a master program that does a lot of processing, and several scripts that receive data from that processing. It's set up in such a way that nearly everything the script would need to process is pre-calculated by the master program. Currently I'm serializing data on one end and deserializing it on the other. 

While this process is efficient, I would like to improve it further. I've looked into IPC (Inter-Process Communication) to improve communication, but before I try to implement it, I need to know if it will even be possible with the way the JVM is set up within TRiBot.

So is this possible?

EDIT: Thanks, I got it working. For future reference, if anyone is considering implementing something like this over Sockets and Streams, it will be effective, but there is risk of memory leaks. This post goes into detail about memory leaks caused by ObjectOutputStreams that are left "on" for long periods of time. The solution is to call #reset() on your ObjectOutputStream on a regular basis to reclaim the memory it consumes to prevent itself from serializing duplicate Objects.

@Fluffee is correct, local sockets would be the most suitable tool for the job. (the other program doesn't have to be Java though, can be any language with socket support), Check out some of Oracle's docs to get started. Using local sockets is nothing more than binding the socket to a local port, this allows for easy refactoring if you ever want to move the external program to a different server, etc.

Alternatively you could also use a message queue like RabbitMQ or Java's Messaging Service (JMS) using OpenMQ. Although either will require dependencies which means that you won't be able to upload the code to the repo.

Interesting, yeah sockets seem to be what I'm looking for. I've no problem doing this with dependencies, it's for a local script which is already set up with Maven. Any word on how this can be done across multiple PCs? Or will it only work on the same machine?

You can just open up a ServerSocket in the external program, bind to a port and make other PCs (tribot) connect to it using a regular Socket and the IP/port of the machine you run the serversocket on. Might have to port forward in your router to open them up if your going over WAN instead of LAN.

These docs should get you going: https://docs.oracle.com/javase/tutorial/networking/sockets/index.html

PM on Discord if you need any more help.

Great, thanks! Wasn't sure where to get started with something like this, that doc will be useful for sure

    • [READ TO THE END FOR A TEASER]

      I've noticed some new TRiBotters have had some troubles finding out sources of how to do certain things, such as using advanced scripts and often get lost in the forums.

      We are still getting posts asking where to start, what to do, recommended scripts, etc. 

      As many of you know, I am new to the team, and had troubles myself learning how to bot, let alone script. 

      So, what our team decided to do was make it easier to learn how to bot, how to script, and just become an overall better botter and scripter faster. 

      As some of you might have seen, I've posted 3 new blogs, you can check it out by clicking on the following picture or here.


      These first 3 blogs are the first of many blogs that will be TRiBot official. They are encouraged to be challenged, improved upon and act as A Best Practices Guide for Botters.

      What information would you like to see in the blogs?

      👇 [TEASER] 👇

      .

      We are going to be hosting a  CONTEST  this  OCTOBER.

      Its scary to think how soon you'll find out.👻

      Stay tuned.

    • Today marks a big day for TRiBot! To make it easier for users to use TRiBot, we've created installers available for every platform! These installers are all bundled with the latest version of OpenJDK 1.8 (Java 😎, which is LG compatible.

      Using TRiBot is now easy. Simply download the installer for your platform, install TRiBot, and run it. The TRiBot Loader will correctly identify the bundled JDK so there's no need to change the Java selection.

      Windows

      EXE installer: TRiBot-windows-x64-4.0.3.exe


      MSI installer: TRiBot-windows-x64-4.0.3.msi


      Portable version: TRiBot-windows-x64-4.0.3.zip


      Mac OS

      Installer: TRiBot-macos-4.0.3.dmg


      Portable version: TRiBot-macos-4.0.3.tgz


      Unix/Linux

      Installer: TRiBot-unix-4.0.3.sh


      RPM installer (CentOS/Fedora): TRiBot-linux-4.0.3.rpm


      DEB installer (Debian): TRiBot-linux-4.0.3.deb


      Portable version: TRiBot-unix-4.0.3.tar.gz


      Platform Independent

      JAR file: tribot-loader-4.0.3.jar


      Note that this jar file does not include the bundled JDK.



      Windows and Mac OS users may notice a warning message stating that the installer/application is un-recognized or un-trusted. Please ignore this message and proceed with running the installer/application. We need to acquire a code signing certificate so that we can sign the installers letting the operating system know that these files can be trusted. It will take a week or more to acquire one, so please hold tight.

      Other notable changes to the TRiBot Loader:

      Support getting the version from OpenJDK distributions


      Add check for bundled JDK


      Copy OpenJDK tools.jar to the bundled JDK if not present


      Set the current java as the first available list entry


      Ignore Java versions which are symbolic links


      Make the bundled JDK the preferred Java version


      Update icon images


      Reduce the number of HTTP calls

    • TRiBot is looking to improve a lot of its customer relationship management, customer on boarding process, customer experience, design elements, community engagement and pretty much everything else you can imagine when it comes to marketing.

      Our goal: To ensure that the marketing done TRULY reflects the experience and does not shine an inaccurate light on what TRiBot is lacking in.

      So I ask, what do you love about TRiBot and what do you hate about TRiBot? What does O S Bot, Rune M8, PowR Bot and Dre amBot do better? (yes I purposely didn't spell it right 😂).

      Love,

    • Hello TRiBot,

      Today we have a significant release that has been in the works for the last month addressing several key issues, features and bugs in the backlog.

      With these changes, we are also including a new TRiBot Loader which will allow you to select any version that is released. This adds the flexibility of allowing you to revert to a previous version should an issue arise, run development only builds, view an accurate change log between versions etc. we are very proud to offer this feature and think it will add a lot more functionality down the road as we continue to release new versions.

      These changes include 80+ commits by our development team, a list of them is summarized below and also available for your viewing pleasure in the new TRiBot Loader.

      In addition, we have taken additional steps to improve as a development team by adding continuous integration and deployment into our workflow to assist in delivering timely releases such as bug fixes as well as new features on a weekly basis depending on our development cycle.
