/** @file framerate_type.h
|
|
* Types for recording game performance data.
|
|
*
|
|
* @par Adding new measurements
|
|
* Adding a new measurement requires multiple steps, which are outlined here.
|
|
* The first thing to do is add a new member of the #PerformanceElement enum.
|
|
* It must be added before \c PFE_MAX and should be added in a logical place.
|
|
* For example, an element of the game loop would be added next to the other game loop elements, and a rendering element next to the other rendering elements.
|
|
*
|
|
* @par
|
|
* Second is adding a member to the \link anonymous_namespace{framerate_gui.cpp}::_pf_data _pf_data \endlink array, in the same position as the new #PerformanceElement member.
|
|
*
|
|
* @par
|
|
* Third is adding strings for the new element. There is an array in #ConPrintFramerate with strings used for the console command.
|
|
* Additionally, there are two sets of strings in \c english.txt for two GUI uses, also in the #PerformanceElement order.
|
|
* Search for \c STR_FRAMERATE_GAMELOOP and \c STR_FRAMETIME_CAPTION_GAMELOOP in \c english.txt to find those.
|
|
*
|
|
* @par
|
|
* Last is actually adding the measurements. There are two ways to measure, either one-shot (a single function/block handling all processing),
|
|
* or as an accumulated element (multiple functions/blocks that need to be summed across each frame/tick).
|
|
* Use either the PerformanceMeasurer or the PerformanceAccumulator class respectively for the two cases.
|
|
* Either class is used by instantiating an object of it at the beginning of the block to be measured, so it auto-destructs at the end of the block.
|
|
* For PerformanceAccumulator, make sure to also call PerformanceAccumulator::Reset once at the beginning of a new frame. Usually the StateGameLoop function is appropriate for this.
|
|
*
|
|
* @see framerate_gui.cpp for implementation
