if partway down there var eventlistings

i code exists in var

any ideas how can this?

thanks

the code have far (basically) function using open-uri ruby standard library. standard library module, require 'open-uri' @ top of file in use it.

open::uri treats job give contents of file. if comfortable using tools search raw text particular contents looking for, may enough. there few gems, though, assume html , provide special support finding html elements , inspecting contents. this post uses mechanize in turn built on top of nokogiri. easier write working code when using library, aware installing nokogiri may difficult in staging or production environment when making decision use it.

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
