Error whit loading sprites

[Matema]

This is the file game.lua:

Code: Select all

local game = {}
local gravity = 100
local score = 0

function game:load()
    arrow = {
        Arrowx = 380,
        Arrowy = 490,
        arrow1 = love.graphics.newImage("assets\arrow.png")
    }
    --enemy = {}
    love.graphics.setBackgroundColor(0, 0, 0)
    love.graphics.setDefaultFilter("nearest", "nearest")
    enemyx = love.math.random(0, 770)--mettere sempre 770
    enemyy = 60 --mettere sempre 60
    enemy.sprite = love.graphics.newImage('assets/blocktest.png')
end

function game:update(dt)
    if love.keyboard.isDown("d") then
        arrowx = arrowx + 10
    end
    if love.keyboard.isDown("a") then
        arrowx = arrowx - 10
    end
end

function game:draw()
    love.graphics.setLineWidth(5)    
    love.graphics.line(0, 540, 800, 540)
    love.graphics.line(0, 480, 800, 480) 
    --love.graphics.polygon("fill", 400, 540, 410, 520, 390, 520)
    love.graphics.draw(arrow.arrow1, arrow.Arrowx, arrow.Arrowy, 0, 2.5, 2.5)
    --love.graphics.draw(enemy, enemyx, enemyy, 0, 1, 1)
   -- love.graphics.print(score, 0, 80)
end

return game

This is the other file menu.lua:

Code: Select all

local menu = {}
local font = love.graphics.newFont("assets/PressStart2P-Regular.ttf", 50)
local Delta = "ΔDelta"
local Start = "Start"
local Exit = "Exit"
local Game = require("game")

function menu.draw()
    love.graphics.setFont(font)
    love.graphics.print(Delta, 0, 300)
    love.graphics.print(Start, 0, 400)
    love.graphics.print(Exit, 0, 500)
end

function menu.keyreleased(key)
        if key == "w" then
            Start = "• Start"
            Exit = "Exit"
        end
        if key == "s" then
            Exit = "• Exit"
            Start = "Start"
        end
        if key == "return" then
            if Start == "• Start" then
                function love.load()
                    Game.load()
                end
                function love.draw()
                    Game.draw()
                end
            end
            if Exit == "• Exit" then
                love.event.quit()
            end
        end
end

return menu

The final file called main.lua:

Code: Select all

function love.load()
    Menu = require("menu")
    Game = require("game")
end

function love.draw()
    Menu.draw()
end

function love.keyreleased(key)
    Menu.keyreleased(key)
end

This is the error that gives me:

Weird naming conventions with lowercase/uppercase, but I would suspect the game:load is not run on load... Test with printing a message or similar debug.

Hi. If I were in your position I'd focus on merging all scripts into a single big script (main.lua) and then work just with that for the time being, until I have more experience with the framework and can expand to other files.

The actual error in your program comes from a misunderstanding of how love.load is used by the LÖVE framework: it's called once after main.lua is parsed and then it's never called again during the program. So if you redefine that function like you're doing in menu.keyreleased(), it still won't be called.
