From e10a2e5999bb646b0145f898328e8f01731ca854 Mon Sep 17 00:00:00 2001 From: Pedro J. Estébanez Date: Sat, 24 Feb 2018 03:04:30 +0100 Subject: Implement universal translation of touch to mouse Now generating mouse events from touch is optional (on by default) and it's performed by `InputDefault` instead of having each OS abstraction doing it. (*) The translation algorithm waits for a touch index to be pressed and tracks it translating its events to mouse events until it is raised, while ignoring other pointers. Furthermore, to avoid an stuck "touch mouse", since not all platforms may report touches raised when the window is unfocused, it checks if touches are still down by the time it's focused again and if so it resets the state of the emulated mouse. *: In the case of Windows, since it already provides touch-to-mouse translation by itself, "echo" mouse events are filtered out to have it working like the rest. On X11 a little hack has been needed to avoid a case of a spurious mouse motion event that is generated during touch interaction. Plus: Improve/fix tracking of current mouse position. --- platform/javascript/os_javascript.cpp | 35 ----------------------------------- 1 file changed, 35 deletions(-) (limited to 'platform/javascript/os_javascript.cpp') diff --git a/platform/javascript/os_javascript.cpp b/platform/javascript/os_javascript.cpp index e226ab633..0f057d929 100644 --- a/platform/javascript/os_javascript.cpp +++ b/platform/javascript/os_javascript.cpp @@ -277,23 +277,6 @@ static EM_BOOL _touchpress_callback(int event_type, const EmscriptenTouchEvent * _input->parse_input_event(ev); } - - if (touch_event->touches[lowest_id_index].isChanged) { - - Ref ev_mouse; - ev_mouse.instance(); - ev_mouse->set_button_mask(_input->get_mouse_button_mask()); - dom2godot_mod(touch_event, ev_mouse); - - const EmscriptenTouchPoint &first_touch = touch_event->touches[lowest_id_index]; - ev_mouse->set_position(Point2(first_touch.canvasX, first_touch.canvasY)); - ev_mouse->set_global_position(ev_mouse->get_position()); - - ev_mouse->set_button_index(BUTTON_LEFT); - ev_mouse->set_pressed(event_type == EMSCRIPTEN_EVENT_TOUCHSTART); - - _input->parse_input_event(ev_mouse); - } return true; } @@ -319,24 +302,6 @@ static EM_BOOL _touchmove_callback(int event_type, const EmscriptenTouchEvent *t _input->parse_input_event(ev); } - - if (touch_event->touches[lowest_id_index].isChanged) { - - Ref ev_mouse; - ev_mouse.instance(); - dom2godot_mod(touch_event, ev_mouse); - ev_mouse->set_button_mask(_input->get_mouse_button_mask()); - - const EmscriptenTouchPoint &first_touch = touch_event->touches[lowest_id_index]; - ev_mouse->set_position(Point2(first_touch.canvasX, first_touch.canvasY)); - ev_mouse->set_global_position(ev_mouse->get_position()); - - ev_mouse->set_relative(ev_mouse->get_position() - _input->get_mouse_position()); - _input->set_mouse_position(ev_mouse->get_position()); - ev_mouse->set_speed(_input->get_last_mouse_speed()); - - _input->parse_input_event(ev_mouse); - } return true; } -- cgit v1.2.3-70-g09d2
