Installation (Windows 10)

It works stably on the Windows 10 command line. In earlier OS versions, updating the command line may be slow.

• Step 1 - clone repository

First of all you need to clone repository. The following command to do it:

git clone https://github.com/Nikita-bunikido/3D-FPS-game-command-line.git

• Step 2 - compile it for yourself

You can do it like that:

cd 3D-FPS-game-command-line
mingw32-make

After that you have a solved .exe file:

./NSHOOT.exe

• Step 3 - setting up multiplayer

If you want to play online with your friend, you need to setup a multiplayer. Your computer and a friend's computer must necessarily be connected to the same local network to play online. Then on your computer in menu of the game you need to choose 's' - Server. And your friend need to choose 'c' - Client. Your friend need to know your IPv4 adress. If you don't know it, open the command line (Win + R), write cmd and paste the command:

ipconfig

Then write this adress on client and enjoy!

If you want to play offline write 'o' - Offline in the menu.

Management

Basic management:

W	A	S	D	SPACE
go ahead	go left	go back	go right	shoot

Mouse for camera rotation.

Features

• All walls textures now in folder 3D-FPS-game-command-line\RES\ You can change it, and after that it will change in the game. It can be avaiable by .txt files parser, integrated in this repository.

• Now you can generate a brightness chars in textures.

=======
=     =
=  ~  =
= ~1~ =
=  ~  =
=  ;  =
=======

This is a texture. It will be the same in game.

4444444
4     4
4  ~  4
4 ~1~ 4
4  ~  4
4  ;  4
4444444

And this is a texture, but 4 and 1 will be visible like chars with brightness 4 and 1.

You can use these characters to make a brigthess chars: 1234
