[Kurogami Neko]

Hello kind humans,
I have been trying for days to import my game.lua to my main.lua. It just won't work
I want game.lua to run after pressing the start game...
I have been trying by watching videos, reading tutorials but IDK how to ! I know how to import simple var like x=1 from other script but dont know how to execute the entire script! Please help...
ps: sorry for the mess in the code.. I have been trying too much

my main.lua

Code: Select all

fullscreen = false
require "game"
Menu = require 'library/menu'


function love.load()
	start = game.f1()
	player = game.f2()
	game = game.f3()

	testmenu = Menu.new()
	testmenu:addItem{
		name = 'Start Game',
		action = function()
			
			start.game.f1()
		
		end
	}
	testmenu:addItem{
		name = 'Load Game',
		action = function()
			-- do something
		end
	}
	testmenu:addItem{
		name = 'Options',
		action = function()
			-- do something
		end
	}
	testmenu:addItem{
		name = 'Quit',
		action = function()
			love.event.quit()
		end
	}

	
end

function love.update(dt)
	testmenu:update(dt)
	
end

function love.draw()
	testmenu:draw(250, 250)--menu table position(x,y)

end

function love.keypressed(key)
	testmenu:keypressed(key)
end

my game.lua

Code: Select all

game = {}

game.f1 = function()
	 anim8 = require 'library/anim8'
	love.graphics.setDefaultFilter("nearest","nearest")

	player = {}   --empty table
	player.x = 400
	player.y = 200
	player.speed = 2
	
	player.spritesheet = love.graphics.newImage('pic/lady.png')
	player.sprite = love.graphics.newImage('pic/parrot.png')
	player.grid = anim8.newGrid(103, 121, player.spritesheet: getWidth(), player.spritesheet: getHeight() )--create grid
--get grid by dividing resolution with 4
	player.animations = {}
	player.animations.down = anim8.newAnimation(player.grid('1-4',1),0.2 )
	player.animations.left = anim8.newAnimation(player.grid('1-4',2),0.2 )
	player.animations.right = anim8.newAnimation(player.grid('1-4',3),0.2 )
	player.animations.up = anim8.newAnimation(player.grid('1-4',4),0.2 )

	player.anim = player.animations.down



	background = love.graphics.newImage('pic/background.png')

	
end

game.f2 = function(dt)
	local isMoving = false

	if love.keyboard.isDown("right") then
		player.x = player.x + player.speed
		player.anim = player.animations.right
		isMoving = true
	end

	if love.keyboard.isDown("left")then
		player.x = player.x - player.speed
		player.anim = player.animations.left
		isMoving = true
	end

	if love.keyboard.isDown("up")then
		player.y =player.y - player.speed
		player.anim = player.animations.up
		isMoving = true
	end

	if love.keyboard.isDown("down")then
		player.y =player.y + player.speed
		player.anim = player.animations.down
		isMoving = true
	end

	if isMoving == false then
		player.anim:gotoFrame(2)
	end

	player.anim:update(dt)
end

game.f3 = function()
	love.graphics.draw(background,0,0)
	--player.anim:draw(player.spritesheet,player.x, player.y, nil, 5)
	player.anim:draw(player.spritesheet,player.x, player.y)
end
return game

Thank you *sobs*

Working code from chatGPT:

Code: Select all

--button.lua
-- Button class
local Button = {}
Button.__index = Button

function Button:new(x, y, w, h, text, action)
    local button = setmetatable({}, Button)
    button.x = x
    button.y = y
    button.w = w
    button.h = h
    button.text = text
    button.action = action
    return button
end

function Button:draw()
    love.graphics.setColor(1, 1, 1)
    love.graphics.rectangle("line", self.x, self.y, self.w, self.h)
    love.graphics.printf(self.text, self.x, self.y + self.h / 2 - 8, self.w, "center")
end

function Button:isClicked(x, y)
    return x > self.x and x < self.x + self.w and y > self.y and y < self.y + self.h
end

return Button

Code: Select all

--menu.lua
-- Menu class
local Menu = {}
Menu.__index = Menu

function Menu:new(buttons)
    local menu = setmetatable({}, Menu)
    menu.buttons = buttons
    return menu
end

function Menu:update(dt)
    -- TODO: handle update logic if needed
end

function Menu:draw()
    for i, button in ipairs(self.buttons) do
        button:draw()
    end
end

function Menu:mousepressed(x, y, button)
    if button ~= 1 then
        return
    end
    
    for i, button in ipairs(self.buttons) do
        if button:isClicked(x, y) then
            button.action()
        end
    end
end

return Menu

Code: Select all

--main.lua
Button = require ("button")
Menu = require ("menu")
-- Example usage
function love.load()
    local buttons = {
        Button:new(100, 100, 200, 50, "Button 1", function() print("Button 1 clicked") end),
        Button:new(100, 200, 200, 50, "Button 2", function() print("Button 2 clicked") end),
        Button:new(100, 300, 200, 50, "Exit", function() love.event.quit( ) end),
    }
    menu = Menu:new(buttons)
end

function love.update(dt)
    menu:update(dt)
end

function love.draw()
    menu:draw()
end

function love.mousepressed(x, y, button)
    menu:mousepressed(x, y, button)
end

The Lua PIL ebook lacks much needed clarity in some parts, like this thing about 'require': it returns the value(s) returned by the script it's loading.
Therefore instead of...

require "game"

... you need to have...

local game = require("game")

That's why you're putting that 'return' at the end of game.lua, after all.

As for it not working, have you ever got it to work at some point?
Instead of trying to do a complex thing at first (menu, gameplay etc), I really suggest going step by step: getting some graphics showing on screen; getting the player to move from keyboard input; getting a workable menu, and so on.

Once you have all these individual parts working isolated (like writing a separate project for each part), then you can try linking them in the same project with state transitions.
Because if you've never written a menu ever before, it's quite a challenge.
