Generate an aoi instance

For the aoi service can be used in many areas, each area use the aoi module should use it's own aoi instance. We use a aoi factory to generate aoi instance, it accept an object as parameter, and return an aoi instance, which can be used to implament the aoi function.

var aoiManager = require('pomelo-aoi');
var config = {
    map : {
        width : 3200,
        height : 2400
    tower : {
        width : 300,
        height : 300

var aoi = qoiManager.getService(config);

Use the aoi service

The aoi instace has the basic interface for aoi action.

    //Add object 
    aoi.addObject(obj, pos);

    //Remove object 
    aoi.removeObject(obj, pos);

    //Update object
    aoi.updateObject(obj, oldPos, newPos);

    //Add watcher 
    aoi.addWatcher(watcher, pos, range);

    //Remove watcher
    aoi.removeWatcher(watcher, pos, range0;

    //updateWatcher(watcher, oldPos, newPos, oldRange, newRange);

More api can be find in aoiService.js.

Handle aoi event

The aoi service will generate event when the status of objects or watchers changes. You can handler these event :

    aoi.on('add', function(params){
        //Handle add event

The event of tower aoi are: 'add', 'remove', 'update' for aoi object, and 'updateWatcher' for watcher. Of course you can ignore all these events without do any effect to aoi function.
