使用ARCore检测点击事件是否击中了已添加的3d对象

问题描述

我正在关注ARCore示例( https://github.com/google-ar/arcore-android-sdk )，而我正在尝试删除已添加的对象3d(Andy).如何检测带有ARCore的轻击事件是否击中了已经添加的3d对象?

I am following the ARCore sample (https://github.com/google-ar/arcore-android-sdk) and I am trying to remove object 3d (andy) already added. How can I detect if an tap event with ARCore hits an already added 3d object?

推荐答案

在这种情况下，使用listener是很常见的方法:

Using a listener is quite common approach in such situation:

private Node getModel() {
    Node node = new Node();
    node.setRenderable(modelRenderable);
    Context cont = this;
    node.setOnTapListener((v, event) -> {
        Toast.makeText(
            cont, "Model was touched", Toast.LENGTH_LONG)   // Toast Notification 
            .show();
    });
    return node;
}
