const mov = world.onTick(async()=>{
    for(const e of world.querySelectorAll('.chicken')){
        await move(e)
    }
})
async function move(entity){
    entity.velocity.y = 0.5 + Math.random()*0.5
    entity.velocity.x = (Math.random()-0.5)*0.5
    entity.velocity.z = (Math.random()-0.5)*0.5 
    await sleep(500)
}

谁知道怎么解决
