在ARKit中向3D模型添加动画 [英] Adding animation to 3D models in ARKit

问题描述

在此视频中，为对象提供了一个动画，使其在放置时悬停在房间周围，然后在被轻击时将其与另一个动画放在一起. 如何在我的项目中添加这种动画? 是添加已动画对象的唯一方法吗?

In this video an object is given an animation to hover around the room when placed and then when tapped it gets dropped down with another animation. How can I add this kind of animations in my project? Is adding an already animated object the only way?

谢谢

推荐答案

我认为上下浮动很可能是动画序列.以下用于悬停效果的动画序列将在第一个下拉选择功能内起作用.

I think the hovering up and down is most likely an animation sequence. The following animation sequence for a hovering effect will work inside the first drop down selection function.

        let moveDown = SCNAction.move(by: SCNVector3(0, -0.1, 0), duration: 1)
        let moveUp = SCNAction.move(by: SCNVector3(0,0.1,0), duration: 1)
        let waitAction = SCNAction.wait(duration: 0.25)
        let hoverSequence = SCNAction.sequence([moveUp,waitAction,moveDown])
        let loopSequence = SCNAction.repeatForever(hoverSequence)
        node2Animate.runAction(loopSequence)

        self.sceneView.scene.rootNode.addChildNode(node2Animate)

点击节点时停止动画的第二部分将其放置在点击手势功能中.

The second part to stop the animation when you tap the node put this inside the tap gesture function.

node2animate.removeAllActions()

最后一部分掉落到地板上，node2animate可能是PhysicalBody，并且在轻击重力属性之前

The last part dropping to the floor, the node2animate might be a physicsBody and before the tap the gravity attribute

node2animate.physicsBody?.isAffectedByGravity = false

点击后将其设置为真

node2animate.physicsBody?.isAffectedByGravity = true

还有其他事情正在进行，还设置了与地板的碰撞等.

There is other stuff going on as well, collision with the floor have also been set etc.
