Bonjour, pour commencer dans ma formation de développeur de jeux vidéo,  je viens de faire une remise à niveau en créant sur l'un des ateliers un jeu Pong.

Voici le résultat en langage Lua, avec le framework LÖve (love2d)

screenWidth = love.graphics.getWidth()
screenHeight = love.graphics.getHeight()

middleScreenW = screenWidth / 2
middleScreenH = screenHeight / 2


rect1 = {
x =15,
y =300,
w =10,
h =100,
SpeedX = 7,
SpeedY = 7

}

rect2 = {
x =770,
y =300,
w =10,
h =100,
SpeedX = 5,
SpeedY = 5

}

ball = {
x =middleScreenW,
y =middleScreenH,
w =10,
h =10,
SpeedX = 7,
SpeedY = 7

}

middleBallx = ball.w/2
middleBally = ball.h/2

middleRecty = rect2.h/2

middleStartRect = middleScreenH - middleRecty


function middleBallFunc()
ball.x = middleScreenW - ball.w
ball.y = middleScreenH - ball.h
ball.SpeedX = 5
ball.SpeedY = 5
end


--var score default
scoreRect1 = 0
scoreRect2 = 0

--list trails

function love.load()

--sound and music
soundFxRect = love.audio.newSource("collide.mp3","static")
soundFxArea = love.audio.newSource("buzzer.mp3","static")

musicBack = love.audio.newSource("music.mp3","stream")

middleBallFunc()

-- start position rect1
rect1.x = 10
rect1.y = middleStartRect

-- start position rect2

--modify size value
