ThreeJS: Remove object from scene
I think seeing your usage for addEntity and removeEntity code would be helpful, but my first thought is are you actually setting the object.name? Try in your loader just before scene.add(object); something like this:
object.name = "test_name";scene.add(object);
What might be happening is the default "name" for an Object3D is "", so when you then call your removeEntity function it fails due to the scene objects name being ""
Also, I notice you pass in object.name to your loader? Is this where your storing the URL to the resource? If so, I would recommend using the Object3D's built in .userData method to store that information and keep the name field for scene identification purposes.
Edit: Response to newly added Code
First thing to note is it's not a great idea to have "/" in your object name, it seems to work fine but you never know if some algorithm will decide to escape that string and break your project.
Second item is now that I've seen your code, its actually straight forward whats going on. Your delete function is trying to delete by name, you need an Object3D to delete. Try this:
function removeEntity(object) { var selectedObject = scene.getObjectByName(object.name); scene.remove( selectedObject ); animate();}
Here you see I lookup your Object3D
in the Three.js Scene
by passing in your object tag's name
attribute. Hope that helps
clearScene: function() { var objsToRemove = _.rest(scene.children, 1); _.each(objsToRemove, function( object ) { scene.remove(object); });},
this uses undescore.js to iterrate over all children (except the first) in a scene (it's part of code I use to clear a scene). just make sure you render the scene at least once after deleting, because otherwise the canvas does not change! There is no need for a "special" obj flag or anything like this.
Also you don't delete the object by name, just by the object itself, so calling
scene.remove(object);
instead of scene.remove(object.name);
can be enough
PS: _.each
is a function of underscore.js
If your element is not directly on you scene go back to Parent to remove it
function removeEntity(object) { var selectedObject = scene.getObjectByName(object.name); selectedObject.parent.remove( selectedObject ); }
