I need to collect data from a 3D object when a roll over event occurs(event.target.variable). I have tried adding a child object, storing the data in the name, even adding a public variable to either the mesh or object .as. All have been rejected. Can anyone give the appropriate method for this, it must be very common, I’ve just can’t find it in the docs. Thanks for any reply.

It’s simple, you should extend Mesh Class suppose we call it CustomMesh and add to it all your custom properties.

Then when you catch the event:

Each Object3D has a property called ‘extra’  this is where you can store arbitrary data.

Ouch…I hadn’t noticed that feature!

Thank you very much, the extra works perfect for me!
