From 8e062f692578d3b32a516401aa732ea8fa516bc4 Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Mon, 19 Mar 2018 14:42:51 -0700 Subject: [PATCH] Generalized the handling of instantaneous guide button presses so there's a minimum of 100 ms between guide button press and release. This happens with at least the following controllers: All Apple MFI controllers, ASUS Gamepad, XiaoMi Bluetooth Controller --- src/joystick/SDL_gamecontroller.c | 36 +++++++++++++++++++++++++ src/joystick/SDL_gamecontrollerdb.h | 1 - src/joystick/SDL_joystick.c | 4 +++ src/joystick/SDL_joystick_c.h | 3 +++ src/joystick/SDL_sysjoystick.h | 1 + src/joystick/iphoneos/SDL_sysjoystick.m | 15 ++--------- 6 files changed, 46 insertions(+), 14 deletions(-) diff --git a/src/joystick/SDL_gamecontroller.c b/src/joystick/SDL_gamecontroller.c index 3326c466f..cdf97e482 100644 --- a/src/joystick/SDL_gamecontroller.c +++ b/src/joystick/SDL_gamecontroller.c @@ -25,6 +25,7 @@ #include "SDL_events.h" #include "SDL_assert.h" #include "SDL_hints.h" +#include "SDL_timer.h" #include "SDL_sysjoystick.h" #include "SDL_joystick_c.h" #include "SDL_gamecontrollerdb.h" @@ -38,6 +39,9 @@ #endif +/* Many controllers turn the center button into an instantaneous button press */ +#define SDL_MINIMUM_GUIDE_BUTTON_DELAY_MS 100 + #define SDL_CONTROLLER_PLATFORM_FIELD "platform:" /* a list of currently opened game controllers */ @@ -112,6 +116,7 @@ struct _SDL_GameController SDL_ExtendedGameControllerBind *bindings;
