# ClockDelta

from direct.distributed.ClockDelta import ClockDelta

The ClockDelta object converts between universal ("network") time, which is used for all network traffic, and local time (e.g. as returned by getFrameTime() or getRealTime()), which is used for everything else.

localElapsedTime

__init__ def __init__(self) Undocumented function.

__resetClock def __resetClock(self, timeDelta) this is called when the global clock gets adjusted timeDelta is equal to the amount of time, in seconds, that has been added to the global clock

__signExtend def __signExtend(self, networkTime) __signExtend(self, int networkTime) Preserves the lower NetworkTimeBits of the networkTime value, and extends the sign bit all the way up.

clear def clear(self) Throws away any previous synchronization information.

getDelta def getDelta(self) Undocumented function.

getFrameNetworkTime def getFrameNetworkTime(self, bits=16, ticksPerSec=NetworkTimePrecision) Returns the current getFrameTime() expressed as a network time.

getLastResync def getLastResync(self) Undocumented function.

getRealNetworkTime def getRealNetworkTime(self, bits=16, ticksPerSec=NetworkTimePrecision) Returns the current getRealTime() expressed as a network time.

getUncertainty def getUncertainty(self) Undocumented function.

localElapsedTime def localElapsedTime(self, networkTime, bits=16, ticksPerSec=NetworkTimePrecision) localElapsedTime(self, int networkTime) Returns the amount of time elapsed (in seconds) on the client since the server message was sent. Negative values are clamped to zero.

localToNetworkTime def localToNetworkTime(self, localTime, bits=16, ticksPerSec=NetworkTimePrecision) localToNetworkTime(self, float localTime) Converts the indicated localTime to the corresponding networkTime value.

networkToLocalTime def networkToLocalTime(self, networkTime, now=None, bits=16, ticksPerSec=NetworkTimePrecision) networkToLocalTime(self, int networkTime) Converts the indicated networkTime to the corresponding localTime value. The time is assumed to be within +/- 5 minutes of the current local time given in now, or getRealTime() if now is not specified.

newDelta def newDelta(self, localTime, newDelta, newUncertainty, trustNew=1) Accepts a new delta and uncertainty pair, understood to represent time as of localTime. Improves our current notion of the time delta accordingly. The return value is true if the new measurement was used, false if it was discarded.

peerToPeerResync def peerToPeerResync(self, avId, timestamp, serverTime, uncertainty) Accepts an AI time and uncertainty value from another client, along with a local timestamp value of the message from this client which prompted the other client to send us its delta information. The return value is true if the other client's measurement was reasonably close to our own, or false if the other client's time estimate was wildly divergent from our own; the return value is negative if the test was not even considered (because it happened too soon after another recent request).

resynchronize def resynchronize(self, localTime, networkTime, newUncertainty, trustNew=1) resynchronize(self, float localTime, int32 networkTime, float newUncertainty) Accepts a new networkTime value, which is understood to represent the same moment as localTime, plus or minus uncertainty seconds. Improves our current notion of the time delta accordingly.
