Stretchy Objects in Unity 3D - Part 2

Bounding forward with our tutorial, in this installment we're going to add the ability to tether the end of a Stretchy object to a local point within the target object. That way, if the object is scaled or rotated, the anchor point will move and rotate appropriately. While we're at it, we'll also add distance margins. Our stretchy classes are becoming more interesting and powerful, so we'll need to take some time out along the way to reorganize the code more smartly, both to appease the code gods and to satisfy the modular Unity paradigm.

Stretchy Objects in Unity 3D

A common problem in graphics is drawing a line from one point to another. In games and simulations we often need to do the same thing using a 3D object. In this article I'll walk through the code you need to stretch a GameObject in Unity3D along a single axis so that its ends remain tethered to two objects as they move around in 3D space. A demo project is included!

Fixing Unity3D Build for iOS Issues

One of the annoying things about the XCode requirement for Unity3D's "Build for iOS" capability is that with each new version of XCode (and sometimes OS X) Unity loses its ability to command XCode to build and run the project. In this article I summarize two solutions: First, a simple patch to make the XCode plugin load. And a "Build for iOS" script that can create an iOS XCode project even when Unity and XCode are having the worst of days. The "Enable Bitcode" error is also covered.

Marlin Configurator - Part 1

All 3D printers require on-board code to translate textual commands (called GCODE) into movement and molten plastic. For this job, most RepRaps (and many commercial 3D printers) rely on Marlin, a compact, adaptable, and streamlined firmware. Marlin's flexibility comes from having a huge number of configurable options. In this article (and accompanying video) I'll be discussing the challenges of building a configurator to help wrangle Marlin's many options, and I'll be showing off some cool Javascript tricks in the process.

Ajaxify Your Drupal Site

Drupal sites are great looking and perform well due to smart caching. But out of the box they still rely on reloading whole pages for site navigation. There are a few modules for applying AJAX to different elements, but none of them fully serve the needs of so I rolled my own solution. Here's the code we use to make our Drupal-style menus load their content into the content region, which should be adaptable to any site. In the future we'll look at building a module out of this code.
