Detailed Description

Time-related functions.

Function Documentation

◆ fsTimeGetDelta()

double fsTimeGetDelta ( void )

Returns the delta time.

Returns the time difference between the current frame and the previous one.

Returns: Delta time.

◆ fsTimeGetSystemTime()

double fsTimeGetSystemTime ( void )

Returns the current system time.

Returns the current system time at the moment this function is called.

Returns: Current system time.

◆ fsTimeGetTime()

double fsTimeGetTime ( void )

Returns the engine running time.

Returns the elapsed time, in seconds, since the time system was initialized with fsTimeInit().

This function provides a monotonic, engine-relative time value and should be used for timing, animations, logging, and time-based calculations inside the engine.

Returns: Time in seconds since fsTimeInit() was called.

Note: This value is independent of the system clock and is not affected by system time changes.; The returned value always increases while the engine runs.

◆ fsTimeInit()

void fsTimeInit ( void )

Initializes the time module.

Initializes the internal time tracking used by the engine.

This function must be called before using any other time-related function.

◆ fsWait()

void fsWait ( long ms )

Waits for a specified duration.

Pauses the program execution for a given number of milliseconds. Works on Windows and POSIX systems.

Parameters

ms	Duration to wait, in milliseconds.

Note: On Windows, uses Sleep().; On Linux/macOS, uses nanosleep() and handles EINTR.
