gemfile

application.js

//= require jquery //= require jquery_ujs //= require turbolinks //= require leaflet //= require leaflet-google //= require leaflet.markercluster //= require_tree

application.css

 *= require leaflet  *= require leaflet.markercluster  *= require leaflet.markercluster.default  *= require_tree .  *= require_self

coffeescript

$ ->     map = l.map("mapid").setview([47.6345153, -122.3208297], 18)     map.options.maxzoom = 22     map.options.bounceatzoomlimits = true     googlelayer = new l.google("roadmap")     map.addlayer googlelayer     markers = l.markerclustergroup()      in[0...10]         markers.addlayer l.marker([47.6345 + (math.random() / 2000), -122.3208 + (math.random() / 2000)])     markers.refreshclusters     map.addlayer markers

any wonderful.

sample of google map leaflet markerclusters not working

as turned out leaflet-markercluster-rails using code leaflet-markercluster 0.4, not more current 0.7. can tell, that's root of entire problem. :)

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
