restrict: 'E'

- Ayant leur propre contrôleur, elles peuvent hériter du `$scope` de leur parent ou être en isolation.
|
||||
- En cas d'isolation, elles peuvent se lier de différentes manières avec le `$scope` de leur parent, notamment
|
||||
via leurs attributs.

- Une directive, contrairement à un simple contrôleur peut manipuler le DOM via sa méthode `link()`.

```html

<script>

angular.module('myApp', [])

.directive('myDirective', function() {
|

return {
|
||||
restrict: 'E',
|
||||
link: function(scope, element, attrs) {
|
||||
|
||||
// scope: $scope de notre directive
|
||||
// element: référence vers l'élément du DOM portant la directive (via wrapper jqLite)
|
||||
// attrs: objet clé/valeur portant les attributs normalisés de l'élément du DOM
|
||||
|
||||
element.text('Hello word !');
|
||||
|
||||
// L'évènement $destroy émit par le scope permet
|
||||
// d'être notifié de la suppression de la directive
|
||||
scope.$on('$destroy', function() {
|
||||
// Faire quelque chose à la destruction de la directive
|
||||
});

<p>Vos deux jours de marche sont enfin terminés. Après avoir ôté votre
|
||||
épée de son fourreau, vous la déposez sur le sol et vous poussez un
|
||||
soupir de soulagement en vous asseyant sur un rocher couvert de
|
||||
mousse pour prendre quelques instants de repos. Vous vous étirez, vous
|
||||
vous frottez les yeux, puis vous levez votre regard vers la montagne au
|
||||
sommet de feu. La montagne elle-même paraît menaçante. Son flanc
|
||||
escarpé, face à vous, semble avoir été déchiqueté par les griffes de
|
||||
quelque créature gigantesque. Il est hérissé d'à-pics rocheux aux angles
|
||||
tranchants dont on a peine à croire qu'ils aient été façonnés par la
|
||||
nature. Au sommet, on aperçoit une couleur d'un rouge sinistre - sans
|
||||
doute l'effet d'une étrange végétation - qui a donné son nom à la
|
||||
montagne. Personne, peut-être, ne saura jamais ce qui pousse là-haut,
|
||||
car il est certainement impossible d'escalader ce pic.</p>
|
||||
|

<p>Votre quête commence maintenant. De l'autre côté de la clairière, il y a
|

l'entrée d'une caverne sombre. Vous ramassez votre épée, vous vous
|

relevez et vous pensez à tous les dangers qui vous attendent. Puis, avec
|
||||
détermination, vous remettez l'épée dans son fourreau et vous vous
|
||||
avancez vers l'entrée de la caverne. Vous jetez un coup d'œil dans les
|
||||
ténèbres et vous apercevez des parois suintantes et sombres ainsi que
|
||||
des flaques d'eau sur le sol de pierre. L'air est froid et humide. Vous
|
||||
allumez votre lanterne et vous faites prudemment quelques pas dans

l'obscurité. Des toiles d'araignées vous balaient le visage et vous
|
||||
entendez le bruit que font sur le sol des pattes minuscules ; ce sont
|
||||
probablement des rats qui prennent la fuite. Vous entrez dans la

caverne. Après avoir parcouru quelques mètres, vous arrivez à une

diabolique besogne sur la personne d'un Nain attaché par les poignets à

un crochet fixé au plafond. Les deux bossus le percent et le découpent

cruellement avec leurs épées. Le Nain pousse un dernier cri, puis se

tait, les yeux fermés. Ses geôliers émettent quelques exclamations

Par la suite, le passage tourne à l'ouest et se rétrécit considérablement.

Vous arrivez à une voûte de pierres qui vous oblige à vous baisser pour

lumière du jour qui s'infiltre par une ouverture au-dessus de vous. Il

vous est impossible de voir où mène la caverne. Vous allumez votre

lanterne pour explorer l'endroit et vous entendez alors un grondement.

Une faible lueur vacille dans les ténèbres. Et soudain, un jet de feu

jaillit des profondeurs de la caverne en vous manquant de peu, et en

brûlant la mousse dont le mur est couvert par endroits ! Vous vous jetez

à plat ventre sur le sol et vous levez les yeux : un énorme DRAGON

émerge de l'obscurité et avance dans votre direction. Des volutes de

fumée lui sortent des narines. Sa peau d'écaillés rougeâtres brille d'une

lueur huileuse. Le monstre est long d'une quinzaine de mètres !

<p>A l'aide de l'épieu et du maillet (ou d'un maillet de fortune si vous n'en
|
||||
avez pas), vous formez une croix et vous avancez vers le Vampire en
|
||||
l'acculant dans un coin. Le Vampire siffle et essaye de vous attraper,
|
||||
mais il ne peut s'approcher de vous. Il sera cependant difficile de lui
|
||||
enfoncer l'épieu dans le cœur. Tandis que vous marchez vers lui, vous
|
||||
trébuchez et tombez. Par un coup de chance, l'épieu est projeté en
|
||||
avant, et atteint le monstre hurlant. Tentez votre Chance. Si vous êtes
|
||||
chanceux, l'épieu transperce le cœur du Vampire. Si vous êtes
|
||||
malchanceux, le Vampire est simplement écorché par le coup (enlevez-
|
||||
lui 3 points d'ENDURANCE) et il vous rejette en arrière vers la porte
|

située à l'ouest. Si vous fuyez par cette porte, <a ng-click="goTo(380)">rendez-vous au 380</a>. Si
|

vous continuez à combattre, <a ng-click="goTo(144)">rendez-vous au 144</a>. Si vous avez eu de la

chance et que vous avez tué le Vampire, vous pouvez chercher son

trésor - <a ng-click="goTo(327)">rendez-vous alors au 327</a>.
