Unity Scripts

Here are a few unity scripts written in C# that are used in my Pluralsight courses.

What does the script do?

This script was written to fix a problem with the AR tools within Unity when multiple VuMarks are within the AR’s camera view.  The VuMarkToScene script finds grandchild of the VuMark that matches the VuMark Id and makes only it active.

*Disclaimer* These scripts have worked for my projects and proof of concepts. Feel free to use them at your own risk.

/*
*******Trigger a scene with Matching Vumark Id***********

Place script on a empty game object that is a child of the VuMark. 
Create empty game objects with matching VuMark Instance Ids.
inside of those empty game objects put in what you want to be active when the VuMark Id id tracked.

1. Vumark
    a. Empty game object with this script (child of VuMark)
        i. Empty game object- named same as VuMark Id (child of empty game object with script)
            1. Stuff you want to show up whe the Vumark ID is found (Child of empty game object with VuMark Id name)
        i. Empty game object- named same as VuMark Id (child of empty game object with script)
            1. Stuff you want to show up whe the Vumark ID is found (Child of empty game object with VuMark Id name)
    You can make as many as you want. The script will look down the list
    and if it finds a matching VuMarkId and a child of the object the script is on, 
    it will make that object active, if not all objects stay inactive

    audio source on a particle system.  

    Place this script on your camera and it will mute all audio for the WaitForSeconds time in seconds.
