javascript - Three.js raycaster.intersectObjects() get empty array -


i tried make world map three.js, , find https://github.com/ftorghele/worldmap, needed. updated three.js , d3.js version according awesome project, have problem on last step mousemove country name

var vector = new three.vector3( mouse.x, mouse.y, 1 ); this.projector.unprojectvector( vector, this.camera ); var raycaster = new three.ray( this.camera.position, vector.subself( this.camera.position ).normalize() ); var intersects = raycaster.intersectobjects( this.scene.children );

i think should change like

let vector = new three.vector3(mouse.x, mouse.y, 1); let raycaster = new three.raycaster(); raycaster.setfromcamera(vector, this.camera); let intersects = raycaster.intersectobjects(this.scene.children, true);

but intersects empty array.

the content of (this.scene.children) enter image description here

thanks!

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
