Rotorz Tile System is an editor extension for Unity which I developed using C#. Originally I created this to facilitate the completion of a project although after having completed the project I thought that it would be fun to release as a product on the fairly newly established Unity Asset Store.
I have maintained and updated the asset since it’s original release 5 years ago including new features, bug fixes along with various reworkings to maintain compatibility with each new Unity release. Since its release the asset maintained a 5 star rating and received lots of good feedback. In particular customers mentioned how happy they were with the high quality support that I was able to provide them with.
Rotorz Tile System has been purchased and used by both small and large studios alike for prototyping and developing production quality levels. Some of these games even implement their own in-game level editors using the API that I exposed for them.
I designed the various user interfaces so that they would be as intuitive to use as possible from the arrangement of controls, icons, to hot keys, to the workflows of actually using them. Where possible the support for features like drag and drop, context menus, etc was implemented so that users can be more productive.
I developed a range of custom editor controls which were designed to improve the overall user experience of the tool. Here are a few of the more obvious custom controls since many of the custom controls use built-in Unity styles.
I designed the editor API with various entry points allowing end-users to implement their own tools, brushes, designers and workflows without the need to modify the original source code. This was in part since the asset was distributed as compiled DLLs but also because it would have been very difficult to maintain if end-users were modifying the original source code.
For the asset store release documentation was authored with the DITA format because this allowed topics to be written and maintained independently of other topics. The open source DITAC tooling made this a good solution. One of the requirements of the asset store was that the documentation be provided with the asset itself. With DITA it is very easy to automate the generation of a PDF as well as the web facing content.
I always strived to provide customers with the best quality and most detailed technical support as possible to help them understand and use the asset. Support was provided via E-mail, support forums and often with screen sharing for remote collaboration.
Rotorz Tile System was integrated into a number of other assets that are available on the Unity Asset Store including PlayMaker, PoolManager and several assets that are nolonger available.
After the five years of development I decided to remove the product from the Unity Asset Store since I believe that it had reached a large volume of the target audience and to instead release it with a permissive open source license so that people can fully customize user experience for their teams.
For the open source release all documentation was converted into the simpler markdown format and I wrote a tool to generate GitHub wiki navigation similar to the original documentation that was generated by the DITAC tooling.
