consoleGameEngine

Here is a demonstration of consoleGameEngine. I used consoleGameEngine to implement tetris. Code for tetris can be found here

Project Overview

This is a simple game engine for C++.

What it does

This is essentially a C++ library that handles most of grunt work for you when make a game.

It first sets up the screen buffer for displaying game output using

void setupScreenBuffer()

Then it handles the game loop using

void runGame()

Inside runGame(), it uses handleInput() and handleOutput() to handle input and output. In particular, it uses the windows console as the screen buffer for video output. And the setupGameAssets() and GameUpdate(fElapsedTime) are abstract methods that you override to implement all the specifics of your particular game

void runGame() {
		gameActive = true;

		setupGameAssets();

		auto startTime = std::chrono::system_clock::now();// time points for handling timing. elapsed time per tick in while loop in particular
		auto endTime = std::chrono::system_clock::now();

		while (gameActive) {
			// game timing: timing is important because some people's computers run faster than others'
			// this_thread::sleep_for(50ms); // one game tick, previous timing code
			endTime = std::chrono::system_clock::now();// calculates elapsed time and updates tp1 for next tick
			std::chrono::duration<float> elapsedTime = endTime - startTime;
			startTime = endTime;
			float fElapsedTime = elapsedTime.count();

			handleInput();
			if (!GameUpdate(fElapsedTime)) {
				gameActive = false;
			}
			handleOutput();
		}

		// display the score after the loop ends
		CloseHandle(hConsole);
		system("pause");
	}

How I built it

I coded it by following along Javidx9's console game engine video. I adapted his ideas based on my own needs and understanding, so I have deleted a lot of code that I don't need yet and changed the naming convention and some functions and variables
