c# - Handle touches not started on the UI -


i seek way handle touches not start on ui elements in unity engine.

the purpose of rotating, panning , zooming in on "map" (it shall called on). if touch down event on of ui elements shall handled ui element instead of map.

i think 1 such example google's maps android application.

i have tried several solutions:

  • mouse events - combines of touches single one

  • input.touches - not know how find out if touch should handled ui element instead (i if possible not use "if"s check if touch on ui element might prove real performance issue)

i seek way handle touches not start on ui elements in unity engine ...but if touch down event on of ui elements shall handled ui element instead of map.

the ispointerovergameobject function used simplify this. if returns false, panning, rotation. if returns true mouse on ui element. better , easier use use boolean variable modifed every ui element. use onpointerclick detect events on ui(map). see this more information.

void update() {     checktouchonscreen(); }  void checktouchonscreen() {     #if unity_ios || unity_android || unity_tvos     if (input.touchcount > 0 && input.gettouch(0).phase == touchphase.began)     {         //make sure finger not on ui element         if (!eventsystem.current.ispointerovergameobject(input.gettouch(0).fingerid))         {             onscreentouched();         }     }     #else     // check if left mouse button clicked     if (input.getmousebuttondown(0))     {         //make sure finger not on ui element         if (!eventsystem.current.ispointerovergameobject())         {             onscreentouched();         }     }     #endif }   void onscreentouched() {     debug.log("touched on screen there no ui");      //rotate/pan/zoom camera here }

i if possible not use "if"s check if touch on ui element might prove real performance issue

there no other way without if statement. simple answer above requires it. doesn't affect performance.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
