Zinnia

A collection of design patterns for solving common problems.

[zin-ee-uh]

Introduction

Zinnia is a collection of design patterns for the Unity software that can be beneficial in (but not limited to) spatial computing development.

Requires the Unity software version 2018.3.10f1 (or above).

Getting Started

Setting up a project

• Using the Unity software version 2018.3.10f1 (or above), create a new project using the 3D Template or open an existing project.
• Ensure the project Scripting Runtime Version is set to .NET 4.x Equivalent.
  • In the Unity software select Main Menu -> Edit -> Project Settings to open the Project Settings inspector.
  • Select Player from the left hand menu in the Project Settings window.
  • In the Player settings panel expand Other Settings.
  • Ensure the Scripting Runtime Version is set to .NET 4.x Equivalent.

Adding the package to the Unity project manifest

• Navigate to the Packages directory of your project.

• Adjust the project manifest file manifest.json in a text editor.

  • Ensure https://registry.npmjs.org/ is part of scopedRegistries.
    • Ensure io.extendreality is part of scopes.
  • Add io.extendreality.zinnia.unity to dependencies, stating the latest version.

  A minimal example ends up looking like this. Please note that the version X.Y.Z stated here is to be replaced with the latest released version which is currently .

  {
    "scopedRegistries": [
      {
        "name": "npmjs",
        "url": "https://registry.npmjs.org/",
        "scopes": [
          "io.extendreality"
        ]
      }
    ],
    "dependencies": {
      "io.extendreality.zinnia.unity": "X.Y.Z",
      ...
    }
  }
  

• Switch back to the Unity software and wait for it to finish importing the added package.

Running the tests

If you want to run the tests that come with Zinnia please follow these steps.

Because Zinnia is a package tests have to be explicitly enabled for this package, before the Test Runner can pick them up.

• Navigate to the Packages directory of your project.

• Adjust the project manifest file manifest.json in a text editor.

  • Ensure io.extendreality.zinnia.unity is part of testables.

  A minimal example ends up looking like this.

  {
    "scopedRegistries": [
      ...
    ],
    "testables": [
      "io.extendreality.zinnia.unity"
    ],
    "dependencies": {
      ...
    }
  }
  

• As noted in the official Unity documentation:

  NOTE: You may need to re-import the package, because the test framework doesn't always immediately pick up changes to the testables attribute.

  • Within the Unity software's Project window expand the Packages node.
  • Right-click on the Zinnia.Unity child node and choose Reimport.
  • Wait for the Unity software to finish re-importing the package.

• In the Unity software select Main Menu -> Window -> Test Runner.

• Within the Test Runner window click on the PlayMode tab and the click Run All button.

• If all the tests pass then the installation was successful.

Note: The tests are not compatible with the Run all in player option.

Updating to the latest version

The package will show up in the Unity Package Manager UI once the above steps have been carried out. From then on the package can be updated by selecting the package in the Unity Package Manager and clicking on the Update button or using the version selection UI.

Naming

Inspired by the Zinnia genus of plants known for their colorful, long lasting flower heads and their great ease to grow from seeds. This repository, much like the Zinnia flower aims to be easy to use and allow your projects to grow and flourish into long lasting, easy to maintain solutions.

Fun Fact: Zinnias have been grown aboard the International Space Station and have demonstrated the capability to blossom in a weightless environment.

Changelog

1.17.0 (2020-05-22)

Features

• Association: determine association by platform, sdk and model (1680f63)

  The PlatformDeviceAssociation component allows the determining of the hardware based on matching patterns of the current platform, the SDK loaded by Unity and the model type.

  As all of these are patterns, then they can be used to search for anything or specific types of setup.

  The LoadedXrDeviceAssociation has now been deprecated as it offers a subset of this new functionality but isn't as powerful.

• Conversion: ability to convert between float and normalized float (b65cd03)

  The FloatToNormalizedFloat allows a float value to be converted into a normalized float (between 0f and 1f) and the NormalizedFloatToFloat allows for a normalized float to be converted to a float value based within the range provided.

  The FloatToBoolean has also had the min/max limit removed so any float value can be used to check to see if it should be within the positive bounds.

• Conversion: option to convert vector2 to signed angle (fd1084d)

  The Vector2ToAngle component now has the option of converting to a signed angle in either degrees or radians.

  This allows an angle range of -180 degrees to 180 degrees instead of 0 to 360 degrees and this will feed in better to the FloatToBoolean when wanting to know if the angle is between a given range as it is possible to do -20/20 as a range whereas it's not possible to do 340/20 as a range.

Bug Fixes

• Extraction: override ClearSource method for generics (6ca9cfb)

  There is an issue with using the Malimbe generated ClearSource method when using it with a generic type property as the actual type may not be a nullable type and the MemberCleared weaved code always tries to set it to null.

  In this regard, it is better to simply override the method and set the property to default. This is not done in Malimbe as providing default as the weaved code is extremely tricky.
