network, or plain old latency, lag, and packet issues. Many times, there are mul-
tiple problems going on at once and they can come from unexpected places, such
as bad values coming from the physics engine or uninitialized variables. When
you get stuck, refer back to the tips in each section and avoid making assump-
tions about what is and is not working. Believable dead reckoning is tricky to
achieve, but the techniques in this gem will help make the process as easy as it
can be.
