i'm trying find more elegant way reduce if statements down, have right little messy , reckon done better, suggestions? if(ship.position.y >= transform.position.y + ybound) { hitbounds = true; } if(ship.position.y <= transform.position.y - ybound) { hitbounds = true; } if(ship.position.x >= transform.position.x + xbound) { hitbounds = true; } if(ship.position.x <= transform.position.x - xbound) { hitbounds = true; } thanks time! update if(mathf.abs(ship.position.x - transform.position.x) >= xbound || mathf.abs(ship.position.y - transform.position.y) >= ybound) { hitbounds = true; } worked treat, million! hitbounds = math.abs(ship.position.x - transform.position.x) >= xbound || math.abs(ship.position.y - transform.position.y) >= ybound;

i've implemented basic tagging in app, posts can filtered tags. there's route in routes.rb that get 'tags/:tag', to: 'links#index', as: :tag however, have url /tags lists tags (triggers index action in tag controller). i've set route up get 'tags' => 'tags#index' in tag view have index.html.erb <% @tags.each |tag| %> <div class="row"> <%= link_to tag.name, tag_path(tag) %> </div> <% end %> the problem <%= link_to tag.name, tag_path(tag) %> leads /tags/:id instead of /tags/:tag , doesn't work. how set up? add following to_param method tag model: def to_param name end

i have tagscontroller class, route following (in routes.rb) resources :tags now, when go http://localhost:3000/tags/test it works correctly. however, when go to http://localhost:3000/tags/c++ rails seems parsing "c++" "c ", results in "404 not found" could give me instructions on how fix this? for rails 4 rails provides constrain options determine regex parameter in routes: this constrains allowing access param /photos/1 or /photos/rr27 resources :tags, constraints: { id: /[a-z][a-z][0-9]+/ } for advance constraint by default :id parameter doesn't accept dots - because dot used separator formatted routes. if need use dot within :id add constraint overrides - example id: /[^/]+/ allows except slash. resources :tags, constraints: { id: /[^\/]+/ } these details of specifying constraint routes. hope can you.
