#SundayHackDay realityScript Snippet for ChakrAR

chakrar.js

/* realityScript is a high-level language I created for rapidly prototyping AR apps in 
   high-pressure time constraint settings such as hackathons. Due to sleep-loss, I think 
   in stream of consciousness and so daisy-chaining is key (but I am also very oldskool and love jQuery)...*/

// 0) prepare an Object3D called "ChakraSet" that has the 7 chakras named "red", "orange,"  
$("#ChakraSet").AddTags(this.each(),"Chakra");

// 1a) Define chakra symbol textures
var dicChakra = {};
dicChakra["red"]="muladhara.png";
dicChakra["orange"]="swadhisthana.png";
dicChakra["yellow"]="manipura.png";
dicChakra["green"]="anahata.png";
dicChakra["blue"]="vishuddha.png";
dicChakra["indigo"]="ajna.png";
dicChakra["violet"]="sahasrara.png";

// 1b) Define the bones to attach each to 
var dicBones = {};
dicBones["red"]="Hips=";
dicBones["orange"]="Spine4";
dicBones["yellow"]="Spine6";
dicBones["green"]="Spine7";
dicBones["blue"]="Neck1";
dicBones["indigo"]="Head";
dicBones["violet"]="Nose";

// 2)  When body is found, attach each chakra to the right bone name
$(".Trackable .HumanBody3D").Mesh("#DefaultBody").AttachChild("ChakraSet",dicBones,MatchKey.Bones); 

// 3) loops thru each element of ChakraSet to create a sphere collider 
$("#ChakraSet").CreateColliders(this.each(),Colliders.Sphere);
