javascript - Loading Multiple Collada Objects in THREE.js -


i loading multiple car models using loop in three.js, problem sometime loads objects time not load objects. example if loop of 3 iteration, load 2 objects sometime, sometime loads 1 , sometime loads 3 objects. don't know why? searched lot can't find thing useful. here code.

for (var k = 1; k <= myworld.noofenemies(); k++) {                  myworld.setworldenemycar(k);                  loader2.load('obj/us/us_police_car.dae', function colladaready(collada) {                     object3 = collada.scene;                      object3.scale.x = object3.scale.y = object3.scale.z = 2;                     object3.updatematrix();                     object3.position.x = myworld.enemycar.position.x;                     object3.position.y = myworld.enemycar.position.y;                     object3.position.z = myworld.enemycar.position.z;                      object3.rotation.x = -(math.pi / 2);                      object3.rotation.z = (math.pi / 2);                     enemymodels.push(object3);                     //localobject.rotation.z = -(math.pi / 2);                     //collidablemeshlist3 = localobject;                     //console.log(collidablemeshlist3);                      // init();                      // animate();                  });              }

after 1 more loader in have init() , animate() functions

loader2.load('obj/us/us_police_car.dae', function colladaready(collada) {                 localobject = collada.scene;                  localobject.scale.x = localobject.scale.y = localobject.scale.z = 2;                 localobject.updatematrix();                 localobject.position.x = 0;                 localobject.position.y = 0;                 localobject.position.z = 0;                  localobject.rotation.x = -(math.pi / 2);                  localobject.rotation.z = (math.pi / 2);                  //localobject.rotation.z = -(math.pi / 2);                 //collidablemeshlist3 = localobject;                 //console.log(collidablemeshlist3);                 //scene.add(localobject);                  init();                  animate();              });

this works fine, can't figure out problem above one.

there seems known issue when re-using same instance of collada loader load multiple collada files.

the following code works reliably me (at least in chrome , firefox):

scene = new three.scene();  // setup lighting etc.  load('/path/somecolladamodel.dae'); load("/path/someothercolladamodel.dae"); load("/path/yetanothercolladamodel.dae");  function load(daelocation){     var manager = new three.loadingmanager();     manager.onprogress = function(item, loaded, total) {         console.log(item, loaded, total);     };      var loader = new three.colladaloader(manager);     loader.options.convertupaxis = true;      loader.load(daelocation, function(collada) {             dae = collada.scene;             dae.position.set(0, 0, 0);              scene.add(dae);             render();         }, function(progress) {             // show progress     }); }

note instantiating new loader every time load model.
