Hexagonal rpg

[schael]

Thank you, it really helps me, I now understand the entire code. do you have a link to nolove ? I can't find it, I saw the main of adaptive invaders instead.

Woaw ! Are color, fonts, graphics music and sound the objects or are they simply tables ?

Code: Select all

function love.load()

	-- Resources
	color =	 {	background = {240,243,247},
				main = {63,193,245},
			text = {76,77,78},
				overlay = {255,255,255,235} }
	font = {	default = love.graphics.newFont(24),
				large = love.graphics.newFont(32),
				huge = love.graphics.newFont(72),
				small = love.graphics.newFont(22) }
	graphics = {logo = love.graphics.newImage("media/logo.png"),
				fmas = love.graphics.newImage("media/fmas.png"),
				set = love.graphics.newImage("media/set.png"),
				notset = love.graphics.newImage("media/notset.png") }
	music =	{	default = love.audio.newSource("media/sawng.ogg") }
	sound =	{	click = love.audio.newSource("media/click.ogg", "static"),
				shush = love.audio.newSource("media/shh.ogg", "static"),
				pling = love.audio.newSource("media/pling.ogg", "static") }
	
	-- Variables
	size = 6				-- size of the grid
	audio = true			-- whether audio should be on or off
	state = Menu.create()	-- current game state
	
	-- Setup
	love.graphics.setBackgroundColor(unpack(color["background"]))
	love.audio.play(music["default"], 0)

end

All data structures in lua are tables. If you ever see someone mention objects in lua they are simply tables that behave like objects, which is less confusing than it sounds.

[Robin]

Functions in the form of love.x.newY (for example love.graphics.newImage), return userdata, which is not the same as a table.

[linux-man]

Just open lua/states.lua and lua/button.lua and see how Menu, Instructions and other tables are created. You are looking at tables with functions connected to events: Objects!

I thing that I will go to read more tutorials than only callback functions before continue this project...
In particular about tile-based scrolling because i want tu us it in this game.

I also have neither an AZERTY keyboard or a number pad. Please implement Arrow keys and WSAD. (Both. Not just one.)

Just to help a little your conversion, here is the Hexagonal code (this time only for cursor keys), and the same code in a OOP way.

Code: Select all

function love.load()
	CelluleHexagonale = love.graphics.newImage("hexagone.png")
	Link = love.graphics.newImage("link.png")
	love.graphics.setBackgroundColor(131,192,240)
	font = love.graphics.newFont(8)
	love.graphics.setFont(font)
	x, y = 0, 0
	dx, dy = 0, 0
end

function love.draw()
	for n = 0, love.graphics.getWidth() / 16 - 2 do
		for m = 0, love.graphics.getHeight() / 24 - 2 do
			if math.fmod(n + m, 2) == 0 then
				love.graphics.draw(CelluleHexagonale ,n * 16 ,m * 24)
				love.graphics.print(n..','..m,n * 16 + 8 ,m * 24 + 12)
			end
		end
	end
	love.graphics.draw(Link,(x - dx)* 16 ,(y - dy) * 24)
end

function love.update(dt)
	local v
	if dx == 0 and dy == 0 then
		if love.keyboard.isDown('left') and love.keyboard.isDown('up') then
			dx, dy = -1, -1
		elseif love.keyboard.isDown('left') and love.keyboard.isDown('down') then
			dx, dy = -1,  1
		elseif love.keyboard.isDown('right') and love.keyboard.isDown('up') then
			dx, dy =  1, -1
		elseif love.keyboard.isDown('right') and love.keyboard.isDown('down') then
			dx, dy =  1,  1
		elseif love.keyboard.isDown('left') then
			dx, dy = -2,  0
		elseif love.keyboard.isDown('right') then
			dx, dy =  2,  0
		end
		x, y = x + dx, y + dy
	end
	if dy == 0 then v = 2 else v = 1 end
	if dx > 0 then dx = dx - dt * v
	elseif dx < 0 then dx = dx + dt * v
	end
	if dy > 0 then dy = dy - dt
	elseif dy < 0 then dy = dy + dt
	end
	if math.abs(dx) < dt * v then dx = 0 end
	if math.abs(dy) < dt then dy = 0 end
end

Thank for the translation, I found a tutorial on C++. I red C tutorials from the same author and I think I will understand after reading this http://www.siteduzero.com/tutoriel-3-11 ... #ss_part_1.

I'm actualy adapting the example in the löve tutorials on tile scrolling for my game so I have two questions :
- Have I to use http://love2d.org/wiki/Quad:setViewport with a tileset ?
- How can I use .XML file made by Tiled map editor ?
