Detailed Description
Timer class for measuring elapsed time or frame time.
[AI] Forward declaration for the central timer used for measuring and providing simulation time.
[AI]
[AI] MxTimer implements a timer utility based on timeGetTime (Windows tick count). It allows measuring elapsed times from a start point, pausing/resuming, and retrieving accumulated times in various formats. It maintains both per-instance state (timer started, running, etc.) and static global values for last calculated/started time. [AI]
Constructor & Destructor Documentation
◆ MxTimer()
| MxTimer::MxTimer | ( | ) |
Constructs and initializes the timer to the current tick count, and resets static globals.
[AI]
[AI] m_isRunning is initialized to FALSE, m_startTime is set to the OS tick count (timeGetTime), and g_lastTimeCalculated is set to m_startTime via InitLastTimeCalculated. [AI]
Definition at line 14 of file mxtimer.cpp.
Member Function Documentation
◆ GetRealTime()
| MxLong MxTimer::GetRealTime | ( | ) |
Retrieves the elapsed real time (in ms) since timer construction or last reset.
[AI]
[AI] Updates g_lastTimeCalculated with the current OS tick (timeGetTime) and returns the difference from m_startTime. [AI]
Definition at line 23 of file mxtimer.cpp.
◆ GetTime()
|
inline |
Returns the current timer value in ms, depending on running state.
[AI]
[AI] If the timer is running, returns g_lastTimeTimerStarted (static, records tick count at last Start); otherwise returns the difference between g_lastTimeCalculated and m_startTime (i.e., elapsed ticks so far). In BETA10, only the second branch is present. [AI]
◆ InitLastTimeCalculated()
|
inline |
◆ Start()
| void MxTimer::Start | ( | ) |
Starts the timer and records the real time when started.
[AI]
[AI] Sets m_isRunning to TRUE and updates g_lastTimeTimerStarted with the elapsed time via GetRealTime. If already running, has no additional effect. [AI]
Definition at line 30 of file mxtimer.cpp.
◆ Stop()
| void MxTimer::Stop | ( | ) |
Stops the timer, updating internal counters to reflect elapsed time until now.
[AI]
[AI] Sets m_isRunning to FALSE, and adjusts m_startTime so that future queries (while stopped) return the total elapsed time up to the call. Implementation is based on the difference between the real time and the last time the timer was started, with a slight adjustment (-5) for original engine logic. [AI]
