babylonjs中的动画位置X和Y

// 创建动画对象
var animationX = new BABYLON.Animation("animationX", "position.x", 30, BABYLON.Animation.ANIMATIONTYPE_FLOAT, BABYLON.Animation.ANIMATIONLOOPMODE_CYCLE);
var animationY = new BABYLON.Animation("animationY", "position.y", 30, BABYLON.Animation.ANIMATIONTYPE_FLOAT, BABYLON.Animation.ANIMATIONLOOPMODE_CYCLE);

// 定义关键帧
var keysX = [];
keysX.push({ frame: 0, value: 0 });
keysX.push({ frame: 100, value: 10 });

var keysY = [];
keysY.push({ frame: 0, value: 0 });
keysY.push({ frame: 100, value: 5 });

// 将关键帧添加到动画对象
animationX.setKeys(keysX);
animationY.setKeys(keysY);

// 将动画对象绑定到物体
box.animations.push(animationX);
box.animations.push(animationY);

// 开始动画
scene.beginAnimation(box, 0, 100, true);
