Detailed Description
Used to store rewind information for a given time for all rewind instances.
Rewind information can either be a state (for example a kart would have position, rotation, linear and angular velocity, ... as state), or an event (for a kart that would be pressing or releasing of a key). State changes and events can be delivered in different frequencies, and might be released (to save memory) differently: A state can be reproduced from a previous state by replaying the simulation taking all events into account.
Constructor & Destructor Documentation
◆ RewindInfo()
| RewindInfo::RewindInfo | ( | int | ticks, |
| bool | is_confirmed | ||
| ) |
Constructor for a state: it only takes the size, and allocates a buffer for all state info.
- Parameters
-
size Necessary buffer size for a state.
Member Function Documentation
◆ isEvent()
|
inlinevirtual |
If this RewindInfo is an event.
Subclasses will overwrite this.
Reimplemented in RewindInfoEventFunction, and RewindInfoEvent.
◆ isState()
|
inlinevirtual |
◆ setTicks()
| void RewindInfo::setTicks | ( | int | ticks | ) |
Adjusts the time of this RewindInfo.
This is only called on the server in case that an event is received in the past - in this case the server needs to avoid a Rewind by moving this event forward to the current time.
Member Data Documentation
◆ m_is_confirmed
|
private |
A confirmed event is one that was sent from the server.
When rewinding we have to start with a confirmed state for each object.
The documentation for this class was generated from the following files:
