Snake game c++ tail class how to add new object
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
i'm a beginner programmer of c++ and i would like some help to continue my snake project.
For making a bit of practice with classes i decided to this program using them to not take the bad habit of use things like hundreads of functions that can be sintethyzed.
My problem comes when i have to make the tail for my snake because for making it with classes i would need a sort of command that "summons" a new tail object in the program.
for example: my head just collided with food and the tail has got to grow, but
how can i summon a new tail object??
here is the code (i will work soon on removing system("cls") later to make the program run smoother):
::::::::::::::::SNAKE.cpp:::::::::::::::::
#include <iostream>
#include <conio.h>
#include <Windows.h>
#include "Head.h"
int score = 0;
int main()
{
HEAD head;
while (1)
{
head.key();
head.movement();
head.show();
if (GetKeyState(VK_ESCAPE) & 0x8000)
{
return 0;
}
Sleep(100);
system("cls");
}
}
:::::::::::::HEAD.h:::::::::::::
#include <iostream>
void gotoxy(int x, int y)
{
COORD coord;
coord.X = x;
coord.Y = y;
SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), coord);
}
class HEAD
{
private:
int x = 20;
int y = 20;
int direction, lastdirection;
public:
void show()
{
gotoxy(x, y); std::cout << "@";
}
void movement()
{
lastdirection = direction;
switch (direction)
{
case 1:
y--;
break;
case 2:
x--;
break;
case 3:
y++;
break;
case 4:
x++;
break;
}
}
void key()
{
//------------directions-----------
if (GetKeyState('W') & 0x8000)
{
direction = 1;
}
if (GetKeyState('A') & 0x8000)
{
direction = 2;
}
if (GetKeyState('S') & 0x8000)
{
direction = 3;
}
if (GetKeyState('D') & 0x8000)
{
direction = 4;
}
//-------specific direction changes--------
if (lastdirection == 1 && direction == 3 || lastdirection == 3 && direction == 1)
{
direction = lastdirection;
}
if (lastdirection == 2 && direction == 4 || lastdirection == 4 && direction == 2)
{
direction = lastdirection;
}
}
};
i hope that you can help me because this is a project that need to finish because for me it is the hardest thing i've ever programmed in c++ (after pong)

Try creating a classTailorTailSegmentor ehatever. Then you can add anstd::vector<TailSegment>to the head class which is a dynamically allocated array so you can insert TailSegments as you want. Then add aAddTailSegmentMethod to your head and call it when you pick up a piece of food. In yourHead::showyou then simply iterate over the tail segments and print them to their position.
