| This document describes the changes introduced with libkdegames v5, which first appeared in the KDE 4.9 release.
| | {{Moved_To_Community|Projects/Games/Porting_to_libkdegames_v5}} |
| | |
| == New components ==
| |
| | |
| * '''KgSound''' provides a simple API for playback of short event sounds. Low latency is achieved through the use of OpenAL, with a Phonon fallback if the required libraries are not available.
| |
| | |
| Also, multiple new components have been added which replace existing components. These can be identified by the common class name prefix "Kg". See [[#Reworked components|]] for details.
| |
| | |
| == Removed components ==
| |
| | |
| * The '''KGGZ''' framework has been removed completely.
| |
| * '''KGameLCD''' — Use QLCDNumber instead.
| |
| * '''KGameMisc''' — Instead of a random name, we advise to use generic names where appropriate.
| |
| * '''KGameProgress''' — Use QProgressBar instead.
| |
| * '''KGameSvgDigits''' — If you need SVG digits, include them in your own SVG theme.
| |
| * '''KGrid2D''' — You'll need to do the math yourself.
| |
| | |
| == Reworked components ==
| |
| | |
| === Difficulty ===
| |
| | |
| '''KGameDifficulty''' has been replaced by the '''KgDifficulty''' and '''KgDifficultyLevel''' classes. KgDifficulty stores the current level by itself, and allows for multiple KgDifficulty instances at the same time, although a singleton is provided by the Kg::difficulty() function. The following table shows how to port KGameDifficulty functions:

| |- style="background: #ececec; white-space:nowrap;"
