NPCs float in the air when using VSE waypoint

[YuqiHuai]

I have some information that might help,

1. Looks like you are trying to make sure the vehicle is on the ground. I am not familiar with useGravity, but I know how to set a waypoint that is on the ground by using raycast

    state = lgsvl.AgentState()
    state.transform = transform
    hit = sim.raycast(state.position, lgsvl.Vector(0, -1, 0), layer_mask)
    state.transform.position = hit.point
    return state

2. #1802 this issue might be helpful.
