From a40168a9d7f13891c541055b167a315eb752cf1d Mon Sep 17 00:00:00 2001 From: Yusuf Ebrahim <45940010+yusufmte@users.noreply.github.com> Date: Tue, 23 Jan 2024 03:45:52 -0500 Subject: New dice-rolling app: InfiniDice! (#1326) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add new App `Dice.h` to randomly roll the dice(s). The number of dice can range from 1-9 (default 1), and the sides can range from d2-d99 (default d2). To have a haptic feedback we make Dice vibrate on roll. Regarding the use of C++ `` library: There are known problems with `rand()` and `srand()` (see https://en.cppreference.com/w/cpp/numeric/random/rand) and the `` library is preferred for this reason. The function used from `` also avoids a very rare bias that would occur using `rand()` and modulo, when `RAND_MAX` is not a multiple of `d` and the initially generated number falls in the last "short" segment. This commit also updates the seed to derive entropy (via `seed_seq`) from a mix of the system tick count and the x,y,z components of the PineTime motion controller -- taking inspiration from and with credit to @w4tsn (https://github.com/InfiniTimeOrg/InfiniTime/pull/1199) Thanks for suggestions: * in Dice, when rolling 1d2, also show "HEADS" or "TAILS" -- suggestion by @medeyko * ui adjustments and result realignment -- suggestion by @Boteium --------- Co-authored-by: NeroBurner Co-authored-by: Riku Isokoski Co-authored-by: Paul Weiß <45500341+Poohl@users.noreply.github.com> Co-authored-by: FintasticMan --- src/displayapp/DisplayApp.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src/displayapp/DisplayApp.cpp') diff --git a/src/displayapp/DisplayApp.cpp b/src/displayapp/DisplayApp.cpp index 938d1179..e5329b2d 100644 --- a/src/displayapp/DisplayApp.cpp +++ b/src/displayapp/DisplayApp.cpp @@ -26,6 +26,7 @@ #include "displayapp/screens/FlashLight.h" #include "displayapp/screens/BatteryInfo.h" #include "displayapp/screens/Steps.h" +#include "displayapp/screens/Dice.h" #include "displayapp/screens/PassKey.h" #include "displayapp/screens/Error.h" -- cgit v1.2.3-70-g09d2
