linearVelocity只要把Y设置成0，就无法按照x或者Z方向移动
let rig:Laya.Rigidbody3D = cube.getComponent(Laya.Rigidbody3D)
rig.enabled=false;
rig.enabled=true;
rig.linearVelocity = new Laya.Vector3(-5,0,0)
Laya.timer.frameLoop(1,this,()=>{
rig.linearVelocity= new Laya.Vector3(rig.linearVelocity.x,0,rig.linearVelocity.z)
console.log("rig.linearVelocity==",rig.linearVelocity);
})
