Dokunmatik giriş etkinliklerini işlemek için diziyi okuyun
Oyun döngünüzde motionEvents. Bu
bu dizilerin son temizlenmesinden bu yana gerçekleşen etkinlikleri içerir.
İçeriklerin sayısı motionEventsCount içinde depolanır.
Oyun döngünüzdeki her etkinliği yineleyin ve yönetin. Bu örnekte
aşağıdaki kod motionEvents işlemini yineler ve bunları handle_event üzerinden işler:
for(size_ti=0;i < mApp->motionEventsCount;++i){GameActivityMotionEvent*motionEvent=mApp->motionEvents[i];intaction=motionEvent->action;intactionMasked=action & AMOTION_EVENT_ACTION_MASK;intptrIndex=(action & AMOTION_EVENT_ACTION_POINTER_INDEX_MASK)>>

These\ncontain events that have happened since the last time these arrays were cleared.\nThe number of events contained is stored in `motionEventsCount`.\n| **Note:** Prior to the addition of `GameActivity`, the `AInputQueue* inputQueue` field was used to handle input events. With `GameActivity`, this field has been removed from the `android_app` and no longer used for handling input events.\n\n1. Iterate and handle each event in your game loop. In this example, the\n following code iterates `motionEvents` and handles them via `handle_event`:\n\n for(size_t i = 0; i \u003c mApp-\u003emotionEventsCount; ++i) {\n GameActivityMotionEvent* motionEvent = mApp-\u003emotionEvents[i];\n\n int action = motionEvent-\u003eaction;\n int actionMasked = action & AMOTION_EVENT_ACTION_MASK;\n int ptrIndex = (action & AMOTION_EVENT_ACTION_POINTER_INDEX_MASK) \u003e\u003e\n AMOTION_EVENT_ACTION_POINTER_INDEX_SHIFT;\n\n struct CookedEvent ev;\n memset(&ev, 0, sizeof(ev));\n\n if (actionMasked == AMOTION_EVENT_ACTION_DOWN ||\n actionMasked == AMOTION_EVENT_ACTION_POINTER_DOWN) {\n ev.type = COOKED_EVENT_TYPE_POINTER_DOWN;\n } else if (actionMasked == AMOTION_EVENT_ACTION_UP ||\n actionMasked == AMOTION_EVENT_ACTION_POINTER_UP) {\n ev.type = COOKED_EVENT_TYPE_POINTER_UP;\n } else {\n ev.type = COOKED_EVENT_TYPE_POINTER_MOVE;\n }\n\n ev.motionPointerId = motionEvent-\u003epointers[ptrIndex].id;\n ev.motionIsOnScreen = motionEvent-\u003esource == AINPUT_SOURCE_TOUCHSCREEN;\n ev.motionX = GameActivityPointerInfo_getX(\n &motionEvent-\u003epointers[ptrIndex]);\n ev.motionY = GameActivityPointerInfo_getY(\n &motionEvent-\u003epointers[ptrIndex]);\n\n if (ev.motionIsOnScreen) {\n // Use screen size as the motion range.\n ev.motionMinX = 0.0f;\n ev.motionMaxX = SceneManager::GetInstance()-\u003eGetScreenWidth();\n ev.motionMinY = 0.0f;\n ev.motionMaxY = SceneManager::GetInstance()-\u003eGetScreenHeight();\n }\n\n handle_event(&ev);\n }\n\n2.
