Question

What's your question?

When I use a drone to take photos in a UE4 environment, I keep the drone only moving a fixed distance in the YZ plane with each step. After a period of time, the drone will not be able to receive control and will hover motionless. After waiting for a while, sometimes it will continue to move, and then most of the time it will not continue to move.
