How can i access construct 3 object instance variable in java script

want to access object instance variable in script, cause right now i'm casting ray from object and object next to other collide with and i want to know that that colliding and casting object is same or not. so for that i need to know that whenever ray is colliding with object then it return that ID to it's previous object

Use the instVars property. (See IInstance documentation)

how can i use in java script ? can you give me example for this. i have try to find many places. I'm not able to find way.

or else can you tell me how can i get the instance value of object which are colliding with ray casting like i can access that object instance variable for compression for other

can any one please help me

Assuming inst is a reference to an instance, and it has an instance variable named myNumber, then you'd write inst.instVars.myNumber to access its instance variable.

If you're not sure about how to get an instance, I'd suggest going through the Learn JavaScript in Construct tutorial series.
