How can I remove all nodes from a scenekit scene?

Hi I am trying to remove all nodes from my Scenekit scene but I cannot for the life of me figure out a way.

It seems logical to me that there must be a function for doing this automatically but I cannot find it.

In context, I am trying to remove all nodes so I can reset my scene, which will happen reasonably often. Perhaps there is another way of doing this and I would be fine with that, I'm not stuck with having to remove all nodes.

Thanks!

Try this (assuming you are using Swift):

rootNode.enumerateChildNodes { (node, stop) in
        node.removeFromParentNode()
    }

Works for me.

For me worked like below:

sceneView.scene.rootNode.enumerateChildNodes { (node, stop) in
node.removeFromParentNode() }

you can either create a new scene or call -[SCNNode removeFromParentNode] on every child node of the scene's rootNode

Where you need to remove all of your nodes, call this (if your scene isn't self, change it):

for (SCNNode *node in [self children]) {
    [node removeFromParent]
}

Additionally, if you need to remove each node except for some, call this (say, we don't want to remove 3 nodes, and they're named a, b, and c)

for (SCNNode *node in [self children]) {
    if (![node.name isEqualToString:@"a"] && ![node.name isEqualToString:@"b"] && ![node.name isEqualToString:@"c"]) {
        [node removeFromParent]
    }
}

Hope this helps!

the simplest way I found to remove all nodes from a scene is:
