Cloning and Picking

Here’s 3.5

OK, so I did find a workaround: The attached puzzle worked (not in the preview window though). The code in the ‘Exec Script’ puzzle is:

// Built-in variables: app, v3d, VARS, PROC
var mouse = new v3d.Vector2();
var raycaster = new v3d.Raycaster();
mouse.set((VARS[‘mouseX’] / window.innerWidth) * 2 – 1, – (VARS[‘mouseY’] / window.innerHeight) * 2 + 1);
raycaster.setFromCamera(mouse, app.camera);

var intersects = raycaster.intersectObjects(app.scene.children);
if (intersects.length > 0) {
VARS[‘temp’] = intersects[0].object.name;
} else {
VARS[‘temp’] = null;
}

This returns the name of the mesh if hit, or null if not.

Thanks,
Jon

Yuri,

I have having difficulty getting the ‘code puzzle’ to work with the 3D embedded. I have the 3D window in an iframe with an id = 3dFrame. I seem to be getting the correct mouse coordinates, but the raycaster doesn’t seem to intersect anything. Any ideas?

Here’s my attempt to refer to the embedded window height and width:
`// Built-in variables: app, v3d, VARS, PROC
var mouse = new v3d.Vector2();
var raycaster = new v3d.Raycaster();
var x = document.getElementsByName(‘3dFrame’);
mouse.set((VARS[‘mouseX’] / x.innerWidth) * 2 – 1, – (VARS[‘mouseY’] / x.innerHeight) * 2 + 1);
raycaster.setFromCamera(mouse, app.camera);

var intersects = raycaster.intersectObjects(app.scene.children);
if (intersects.length > 0) {
VARS[‘temp’] = intersects[0].object.name;
} else {
VARS[‘temp’] = null;
}

Yuri,

I tried something slightly different. If you look at the visual_logic.js content and go to the function initObjectPicking function inside registerOnClick, this changed from 3.4 to 3.5:

if (!isPicked) {
_pGlob.pickedObject = ”;
cbIfMissedDo(event);
}

if I change this to as it was in 3.4, any intersected object from the mouse event gets returned with PickedObject, but isPicked remains false:
if (!isPicked) {
_pGlob.pickedObject = objName;
cbIfMissedDo(event);
}

I changed this in the visual_logic.js and it works as before. Any chance this could be put back into 3.5? If not, I can just remember to tweak it.

Thanks,
Jon
