PSP 개발자료 – 키 입력 받는 소스

키 입력 받는 소스

예전에 PSP 개발을 함참할때 만들었던 소스를 찾아서 포스팅합니다.
이걸 지금 사용하는 분들이 있을지 모르겠네요!!!

pspinput.cpp 소스

   psp_key_up = 0; 
 
   for(k = 0x0001 ; k <= 0x8000 ; k <<= 1) 
   { 
      if((psp_key_pressed_old & k) && !(psp_key_pressed & k))    
         psp_key_up |= k; 
      if(!(psp_key_pressed_old & k) && (psp_key_pressed & k))    
         psp_key_down |= k; 
   } 
   psp_key_pressed_old = psp_key_pressed;    
   return 0; 
}

pspinput.h 소스파일

#ifndef _PSP_INPUT_INCLUDED
#define _PSP_INPUT_INCLUDED
 
int SetKeyStatus();
unsigned long GetKeyUp(int type);
unsigned long GetKeyDown(int type);
unsigned long GetKeyPressed(int type);
void KeyInit();
 
#endif // _PSP_INPUT_INCLUDED

 

사용법

KeyInit(); // Key 입력 받기 설정
 
unsigned long key;
key = GetKeyDown(0);
if (key & PSP_CTRL_UP) {
    //십자키 위
}
if (key & PSP_CTRL_DOWN) {
    //십자키 아래
}
