Once upon a time, I tried to build a 3D engine from scratch. The moment I realized I needed to dive into some higher mathematics in order to perform proper rotations, I kinda walked away and left it unfinished. Example 1: Opens and displays a...
Here's a little physics demo I wrote to kill some time at work... Enjoy. :) Open the attached JAR file and/or download the source code. PhysiX.b4j #Region Project Attributes #MainFormWidth: 600 #MainFormHeight: 400 #End Region Sub...
Ok, this is just being silly now. I recently lost a huge chunk of my b4j source code after debugging and I was just reluctant to rewrite it. Well my "Main" file got filled with NULLs after a computer crash. I wanted my data back, urgently and...

Just a little test project for a client I did the other day using B4J and B4A. I may post the code later if I ever get the time. The basic idea was to interface an old rotary phone with a modern cellphone. So, I used a Raspberry Pi 2 to do the...

In researching different ways to do collision detection on my game, I accidentally discovered what can be an alternative to Bresenham's algorithm. What is Bresenham's algorithm? Bresenham's line algorithm is an algorithm that determines the...
when 2 cells collide in the middle they will unite. as bigger the cell as slower it will move. animation end when all cells are united :p
The WeatherCubeOne2 showcase is a next development based on WeatherCubeOne1. This version is completely rewritten using MQTT technology. MQTT is a great Technology - the new solution is so much simpler then the previous - No need for complex...
Hi, whilst progressing with my Domoticz Home Automation Solution, a new Tool Shed ("Gartenhaus") is in the make. This shed will have several sensors (like TinkerForge Bricks/Bricklets, but also planned an Arduino) connected to a Raspberry Pi...

LauncherTool is a utility for B4X developers that has the ability to create and manage projects from a central location. LauncherTool is based off of my previous Launcher-type app which was called “B4L”. However, the major issue with B4L is that...
Hi all. Thought I would share this before I customized it. It is the start of a monitor application to watch MQTT messages. I need it for one of my b4a apps for debugging purposes. I wrote another one in VB.NET 2 years ago but cannot find the...

Hi I develop software for encrypt and decrypt string with password This software develop with B4j (Thanks Erel) I use B4xEncryption that you can use it in B4i,B4a,B4j In this software you enter text and password and get encryption text And use it...
This is an application of necessity for me. Working on a larger project, I needed to make sure I was writing the data as I wanted it. However, I had to write a lot of Log() statements to see what was going into the KVS file. KeyValueStore...
Created this in B4J. Now I am stuck. What do you think, good, boring, too easy? Please feel free to comment (even if you think its crap!!). Next stage is maybe music and a nudge function. Edit: Sorry, forgot to say. Requires Libraries: jCore...
My first app is a file shredder that exceeds government and military standards for data destruction. It uses 21 passes with several different overwrite methods, and it implements another process on top of them. Beauty of this with B4J is that...
The App I build will show that B4J has much Potential. Busy for years with ANPR I have thinking to give it a try to use B4J for it. The App i made is just a test app to create a B4J Wrapper for the Library's I need.. The Library's also making...
My current fun project is a controller for our small familiy aquarium (fish tank) we bought last christmas. The light for the aquarium was 20 years old and I decided to replace it with LED stripes. Since the LED stripes I bought were far too...
