Specific creation methods and steps
- New projects
2. establish Win32 Console Application 
3. next step
4. choice Console Application and Empty item 
5. stay Resource file Right click on the folder , One choice add to - New item 
5. choice C++ file , Input file name , There is no need to add a suffix 
6. Add code
Copy and paste the complete code above . If you use the original author's code, you need to add or cancel Unicode Macro definition and addition tchar.h The header file .
7. After adding the code ,VC2010 The program will load automatically External dependencies , Wait for loading , Click the run debug icon button .
8, Debug window , The interface is black , Press any key , Start entering the game 
8. When the game starts , The keyboard needs to be switched to uppercase input mode , That is to say CapsLk Key , To control the game .
9. Key ：A S W D also Space Key ,
- Related macro definitions of control keys , It can be set according to the keyboard of personal computer .
