I will post 3 pieces of code: my main.lua function, the Ball class, the Paddle class
(obs: when I was testing the printf method before actually starting developing the game it worked. But not anymore)
MAIN FILE
Code: Select all
push = require 'push'
Class = require 'class'
require 'Paddle'
require 'Ball'

function love.load()
love.window.setTitle('PONG')
love.graphics.setDefaultFilter('nearest', 'nearest')
math.randomseed(os.time())
titleFont = love.graphics.newFont("ARCADECLASSIC.ttf", 60)
push:setupScreen(VIRTUAL_WIDTH, VIRTUAL_HEIGHT, WINDOW_WIDTH, WINDOW_HEIGHT,
{
fullscreen = false,
resizable = false,
vsync = true
}
)
player1Score = 0
player2Score = 0
player1 = Paddle(10, 30, 5, 20)
player2 = Paddle(VIRTUAL_WIDTH - 10, VIRTUAL_HEIGHT - 30, 5, 20)
ball = Ball(VIRTUAL_WIDTH/2-2, VIRTUAL_HEIGHT/2-2, 4, 4)
gameState = 'start'
end
function love.draw()
push:apply('start')
love.graphics.setColor(1, 1, 1)
player1:render()
player2:render()
ball:render()
love.graphics.setFont(titleFont)
love.graphics.printf('PONG', 0, WINDOW_HEIGHT/2-6, WINDOW_WIDTH, center')
push:apply('end')
end

end
