[英]How to create Animation (changing Scaling, Rotation or Position) for a Node in ARCore Sceneform?
I'm using ARCore Sceneform
libraries in Android Studio.我在 Android Studio 中使用 ARCore Sceneform
库。 I'm having trouble to find a method to perform a scaling animation to a node when it is set to enable (like the Quaternion
used to rotate a node in Solar System by Google).当节点设置为启用时,我很难找到对节点执行缩放动画的方法(例如 Google 用于在太阳系中旋转节点的Quaternion
)。
//On Tap Listener
scannerVisual.setOnTapListener(((hitTestResult, motionEvent) -> {
// NodeAnimator arrow = new NodeAnimator(true);
//arrow.setParent(scanner);
Node arrowVisual = new Node();
//StackOverflow Solution
arrowVisual.setLocalPosition(new Vector3(0.5f, 0.0f, 0.0f));
arrowVisual.setLocalScale(new Vector3(0.03f, 0.03f, 0.06f));
arrowVisual.setRenderable(arrowRenderable);
arrowVisual.setParent(scanner);
// arrowVisual.setLocalRotation(Quaternion.axisAngle(new Vector3(0.0f, 1.0f, 0.0f), 90));
})
);
I have something like this.我有这样的事情。
You need to set a local scale of the node before
setting its parent. before
设置其父节点before
您需要设置节点的本地比例。 The code should look like this:代码应如下所示:
Anchor anchor = hitResult.createAnchor();
AnchorNode anchorNode = new AnchorNode(anchor);
node.getScaleController().setMinScale(0.5f);
node.getScaleController().setMaxScale(3.0f);
node.setLocalScale(new Vector3(2.25f, 2.25f, 2.25f));
node.setParent(anchorNode);
Hope this helps.希望这可以帮助。
