The best multiplayer game: Pixel Gun .

This game is a very good online game for any child and parent of any age.
The game comes with the ability to play a campaign, make servers (with and without the password), create a fun space where you can meet and chat, create castles and clans.
The game allows duels between teams, conquering the flag, choosing a pet, customizing the player with weapons and accessories, creating a space for each player. You can also create friends, invite and like them.
Pixel Gun 3D has two modes: a single-player Survival Mode and Multiplayer Mode.
First the single-player can be start with with a multi-level campaign and an interesting comic book story.
Into this story, you run around shooting mostly undead enemies like zombies and skeletons and earn points.
The Multiplayer Mode where you join others in a shoot-or-be-shot contest come with many servers and options to do that.
You can also create your own skin, update your clan castle and environment ( like pet house).
I could enumerate the options and features of this game but let you discover it.
I've spent hours playing this game and it's one of the fastest and does not require a lot of resources.

• Physical properties (mass, area, density etc.)
• Restitution (elastic and inelastic collisions)
• Collisions (broad-phase, mid-phase and narrow-phase)
• Stable stacking and resting
• Conservation of momentum
• Friction and resistance
• Events
• Constraints
• Gravity
• Sleeping and static bodies
• Plugins
• Rounded corners (chamfering)
• Views (translate, zoom)
• Collision queries (raycasting, region tests)
• Time scaling (slow-mo, speed-up)
• Canvas renderer (supports vectors and textures)
• MatterTools for creating, testing and debugging worlds
• World state serialisation (requires resurrect.js)
• Cross-browser and Node.js support (Chrome, Firefox, Safari, IE8+)
• Mobile-compatible (touch, responsive)
• An original JavaScript physics implementation (not a port)

You can see one good example here.
How can be used ?
First, get a stable release and include the script in your web page and add the matter engine objects and features, see this example:

News: The new Gimp version 2.9.8 released .

The Roblox game with lua scripting .

The Roblox game is a massively is a multiplayer online game.
This game platform that allows users to design their own games and play a wide variety of different types of games created by the developer or other users.
The programming issues for this game can be solved with lua scripting language.
In this tutorial I will show you how to start programming this game.
First yo need to install the game, make one account and take from web the Studio.
This allow you to make game and changes into your account .
You can start with your place or create a new place .
The Roblox Studio use Workspace with many objects like: bricks , materials, etc.
The next image show you how to select command Bar (1) and Output (2) windows for testing lua commands and see the outputs of this commands from VIEW menu:

Into the next image you can see how I used the lua scripting to print to output:

Use the blue cross from Explorer to add your lua script to the object or part of object:

When all of your changes are done then you can publish to Roblox from File menu.
I preferred not to introduce a classic example script because you can do a lot of useful scripts in the roblox game: effects, automation, animations, music and video, character creation and objects, scripts for online.
You can learn more about this issue if you take a look at this official roblox channel for scripting.

The online CoSpaces Maker for kids to code.

The team development tell us:
Imagine and create. Build a virtual world on any device with the CoSpaces Maker app and explore them in virtual reality. Design, develop and code your own creations or take inspiration from what others have built in the CoSpaces Maker gallery - all you need is a smartphone and a cardboard headset!

First you need to make an account.
The next step is to see all scenes and read how to deal with objects and features.
This features start from load objects, deal with objects, use camera, use scene and code.
To code you need to use blockly - the most simple way to code .

If you think this is to simple and the result will be unsatisfactory, then you'd better take a look here.
You can test online at CoSpaces - official website.

Love2d - the most simple game engine with Lua programming language .

The development team tell us about this software:
Hi there! LÖVE is an *awesome* framework you can use to make 2D games in Lua. It's free, open-source, and works on Windows, Mac OS X, Linux, Android and iOS.
Even if they say it is a framework, most of them who use it already consider it a game engine. You can download it and read about this game engine on the official website After download you need to create a project folder and put the lua scripts for love .
I named this folder test.
I add to this folder one transparent image from internet with the filename: oldpaper.png, see next image:

I create a file named main.lua and I add this lua script:

local imageFile

function love.load()

    imageFile = love.graphics.newImage("oldpaper.png")
end

function love.grid_text()
local gx = 0 
local gy = 0
local g = 0
 while g ~= 100 do
    love.graphics.line( gx, 0, gx, 10)
    love.graphics.setColor( 111, 255, 255 )
    love.graphics.line( 0, gy, 10, gy)
    love.graphics.setColor( 111, 255, 255)
    gx=gx+50 
    gy=gy+50 
    g=g+1
 end
    love.graphics.setColor( 16, 5, 255)
    love.graphics.print("Hello world ! Lua and Love 2D for games !", 290,400)
    love.graphics.setColor(0, 0, 0)
end

function love.draw()
    love.graphics.setBackgroundColor(0, 0, 0)
    love.grid_text()
 -- this displays the normally colored image
    love.graphics.setColor(255, 255, 255, 255)
    love.graphics.draw(imageFile,250,100)
end

Run it outside of test folder with:

 love.exe test

The result of this code is this screenshot.

Unity 3D and the Puppet2D tool .

This tool can help you to animate sprites with Unity 3D.
