ruby - Sinatra/Rack params[] in before block -

-

i'm making site using sinatra, going well, or until needed access params[] hash in before block.

basically, i'm trying this:

before   if params[:forum_id]     @forum = forum.find(params[:forum_id])     build_breadcrumbs(@forum.parents)     # ... more code, snipped keep short   end end

but thing is, can't call params[] hash in before block, have ideas?

the reason i'm putting code in before block because i'd rather not have go , put in every 1 of get , post blocks every page.

from docs:

before filters evaluated before each request within same context routes , can modify request , response.

since happens before actual request, can't access request parameters. can put repetitive code method , call in route blocks.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
