From 726de453bb7f1ef19349cd8833d0a3bacb4b1a44 Mon Sep 17 00:00:00 2001 From: Lioncash Date: Mon, 13 Dec 2021 21:09:28 -0500 Subject: common/input: Avoid numerous large copies of CallbackStatus CallbackStatus instances aren't the cheapest things to copy around (relative to everything else), given that they're currently 520 bytes in size and are currently copied numerous times when callbacks are invoked. Instead, we can pass the status by const reference to avoid all the copying. --- src/input_common/helpers/touch_from_buttons.cpp | 11 +++++++---- 1 file changed, 7 insertions(+), 4 deletions(-) (limited to 'src/input_common/helpers/touch_from_buttons.cpp') diff --git a/src/input_common/helpers/touch_from_buttons.cpp b/src/input_common/helpers/touch_from_buttons.cpp index 35d60bc909..ece1e3b32d 100644 --- a/src/input_common/helpers/touch_from_buttons.cpp +++ b/src/input_common/helpers/touch_from_buttons.cpp @@ -14,10 +14,13 @@ public: using Button = std::unique_ptr; TouchFromButtonDevice(Button button_, int touch_id_, float x_, float y_) : button(std::move(button_)), touch_id(touch_id_), x(x_), y(y_) { - Common::Input::InputCallback button_up_callback{ - [this](Common::Input::CallbackStatus callback_) { UpdateButtonStatus(callback_); }}; last_button_value = false; - button->SetCallback(button_up_callback); + button->SetCallback({ + .on_change = + [this](const Common::Input::CallbackStatus& callback_) { + UpdateButtonStatus(callback_); + }, + }); button->ForceUpdate(); } @@ -47,7 +50,7 @@ public: return status; } - void UpdateButtonStatus(Common::Input::CallbackStatus button_callback) { + void UpdateButtonStatus(const Common::Input::CallbackStatus& button_callback) { const Common::Input::CallbackStatus status{ .type = Common::Input::InputType::Touch, .touch_status = GetStatus(button_callback.button_status.value), -- cgit v1.2.3
