Class RemoteTimeSource

java.lang.Object

com.simsilica.ethereal.net.RemoteTimeSource

All Implemented Interfaces:

SynchedTimeSource, TimeSource

public class RemoteTimeSource
extends java.lang.Object
implements SynchedTimeSource

Keeps track of the latest time included in messages from the server to guess at a consistent time offset for this client. The idea is to roughly simulate that the times coming in from the server represent "now" when they arrive.

Method Detail

setOffset

public void setOffset(long offset)

Description copied from interface: SynchedTimeSource

Sets a time that will be automatically added into the normally returned time. This allows getTime() to return time in the past for interpolating object state buffers.

Specified by:

setOffset in interface SynchedTimeSource

getOffset

public long getOffset()

Description copied from interface: SynchedTimeSource

Returns the current time offset for this TimeSource.

Specified by:

getOffset in interface SynchedTimeSource

updateDrift

protected void updateDrift(long serverTime)

update

public void update(ObjectStateMessage msg)

getTime

public long getTime()

Description copied from interface: TimeSource

Returns the current time in nanoseconds.

Specified by:

getTime in interface TimeSource

getDrift

public long getDrift()

Description copied from interface: SynchedTimeSource

Returns the current drift if there is one. In a remote time source, the drift is the offset from current time and is related in a loose way to both the ping time of the server and the general time difference of the server.

Specified by:

getDrift in interface SynchedTimeSource
