Build command @ Terminal for Linux
	added optimization (20 seconds on Terminal)
	g++ -o altayTerm Altay.cpp -lX11 -lGL -lpthread -lpng -lasound -lstdc++fs -std=c++17 -O3

	alternative:
	g++ -o altayTerm Altay.cpp -lX11 -lGL -lpthread -lpng -lstdc++fs -std=c++17 -Ofast

	game plays at 20fps on my Linux VirtualBox (Pardus, 2GB RAM, 3d Acceleration ON.).

	to install olcPixelGameEngine dependencies on Linux:
	sudo apt install build-essential libglu1-mesa-dev libpng-dev

	to install ALSA sound libraries
	sudo apt install libasound2-dev

To build the game on Windows, check Javidx9's videos (e.g. use Visual Studio 2019 Community Edition)


++ added Timer (thx Cherno) to see how long a function takes.

float distance(const float x1, const float y1, const float x2, const float y2) {
		Timer timer;
		return (x2 - x1) * (x2-x1) + (y2 - y1) * (y2 - y1);
	}

Drawing the whole screen is the bottleneck for Linux.
	[] Maybe worth Using decals? Possible?

Timing certain parts of the code:
	// Altay includes performance measurement functionality. 
	// Cherno style, ref: https://www.youtube.com/watch?v=YG4jexlSAjc
	// Usage: instantiate a Timer struct inside the scope you want to measure.
	// upon exit from scope, it will output the time diff to the console.
	{
		Timer timer;
		DrawSprite(0, 0, buffBack); //this is the bottleneck for Linux.
	}
