How do I create a Classic Snake Game using Open Frameworks and the C++ language so what exactly goes in the main.cpp, ofApp.cpp, and the ofApp.h and within the ofApp.cpp what goes under things such as voidofApp::update and other categories? In the ofApp.h I'm starting with this below which is creating the different windows.

#pragma once

#include "ofMain.h"

class ofApp : public ofBaseApp{

int status {};

void startScreen();

void playScreen();

void pauseScreen();

void overScreen();

public:

void setup();

void update();

void draw();

void keyPressed(int key);

void keyReleased(int key);

void mouseMoved(int x, int y );

void mouseDragged(int x, int y, int button);

void mousePressed(int x, int y, int button);

void mouseReleased(int x, int y, int button);

void windowResized(int w, int h);

void dragEvent(ofDragInfo dragInfo);

};
