javascript - Angular inline Filter "controller side" -


i have selection of categories returned after selection correctly html view {{cat}} display comics if comics selected list

$scope.selectcategory = function (newcategory) {        console.log(newcategory);         $scope.cat = newcategory;         selectedcategory = newcategory;         $scope.selectedpage = 1;     }

however want filter array of objects category controller side not usual inline filters in view i'm aware of

if manually add category in example below comics

$scope.edition_products = $filter('filter')  ( $scope.filtereditems, {approved: true, category: "comics"});

only category comics approved true returned filter works

but how make dynamic injecting inline $scope.cat

e.g. 

$scope.edition_products = $filter('filter') ( $scope.filtereditems, {approved: true, [$scope.cat]}

note not work

filter in controller doesn't automatically trigger. have run filter each time select category, in selectcategory function have re-run filter

such 

$scope.selectcategory = function (newcategory) {    console.log(newcategory);    $scope.cat = newcategory;    selectedcategory = newcategory;    $scope.selectedpage = 1;    $scope.edition_products = $filter('filter')($scope.filtereditems {approved: true, category: $scope.cat}); }

doing filter data each time change category.

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
