|
A simple class to handle simple predictable values
|
||
|
|
on multiplayer clients.
|
||
|
|
|
||
|
|
The class encapsulates the actual value to be stored
|
||
|
|
as well as the client frame number on which it is set.
|
||
|
|
|
||
|
|
When reading predicted values from a snapshot, the actual
|
||
|
|
value is only updated if the server has processed the client's
|
||
|
|
usercmd for the frame in which the client predicted the value.
|
||
|
|
Got that?
