I want to be able to move 3*3 squares like the Rockman Executive.

#include "DxLib.h"

int Key [256]; // Store the number of frames pressed by the key

// update key entry status
int gpUpdateKey(){
    char tmpKey [256]; // Store the current key input state
    GetHitKeyStateAll(tmpKey); // Get all key input states

    for(inti=0;i<256;i++){
        if(tmpKey[i]!=0){//i key code has been pressed
            Key[i]++; // Add
        }
        else {// If not pressed
            Key[i] = 0; // 0
        }
    }
    return 0;
}
