Go language Greed pc egg set the difference between a dragon eating snake and C language

Use GOPC egg to build a dragon, need to search dsluntan.com, language write snake game then will use the object-oriented thinking to write, create a snake body object, and then write out,/go language writing when we need to call a C language to write a package/, The go language can call the C language function directly, very convenient and concise, we first look at my own written C language of a package

Package Clib

/*
#include <windows.h>
#include <conio.h>

Use the WINAPI to move the console cursor
void Gotoxy (int x,int y)
{
COORD C;
C.x=x,c.y=y;
SetConsoleCursorPosition (GetStdHandle (Std_output_handle), c);
}

Gets the key once from the keyboard, but does not display to the console
int Direct ()
{
return _getch ();
}
Remove the console cursor
void Hidecursor ()
{
Console_cursor_info CCI;
cci.bvisible = FALSE;
cci.dwsize = sizeof (CCI);
Setconsolecursorinfo (GetStdHandle (std_output_handle), &cci);
}
*/
Import "C"//Can embed C function in Go

//Set console cursor position
func gotopostion (X int, Y int) {
//Call C language function
C.gotoxy (C.int (X), C.int (Y))
}
// No explicit get keyboard input character
Func Direction () (key int) {
key = Int (C.direct ())
return
}
//Set console cursor Hide
func hidecursor () {
C.hidecursor ()
}

-----this package writes some functions that need to be used in C, and calls C's functions to use the C language environment. Don't forget to install the C language environment on your computer. Let's have a look at this directory structure
write a description of the image here

First of all, our code is placed in the gocode below the SRC directory below, clib inside is the C language of their own package, bulimia Snake and Clib is the same level of directory, where we use the Goland compiler, the compiler can choose its own, we compile the time cannot be compiled by a single file , because you need to call your own package, so choose Multi-file compilation
Write a picture description here
I use the Goland compile time need to change to directory and then the directory is selected in the directory of the SRC directory, and then set up can be directly compiled to run, of course, can also be directly command-line compilation run
Write a picture description here
, we can go to build directly under the directory./This is the build executable. exe, or you can directly compile and run directly using the Go Run command.
Interested partners can try it out for themselves
The following is a look at the code of the Go language, (you can improve their own, such as adding the level, add obstacles, the speed of the snake is self-adjustable)
