LÖVE

Posted: **Thu May 07, 2015 3:53 pm**

Hey there,

So, I'm relatively new to the Löve API.
(I say relatively because I've taken frequent breaks, and constantly forget all about everything.)
I've recently been inspired to create a little RPG-esque game, to learn the quirks in the LÖVE API and to further improve my programming knowledge. I found out about Simple Tiled Implementation after having used Tiled for Unity projects, but I just cannot seem to get it to work.
As of right now, I do not really have any structure to my directories, and am just looking to actually render a Tiled map successfully.

So, to the problem.
When I draw the map, it is really zoomed in, and I just cannot seem to get why.

main.lua

Code: Select all

debug = false
speed = 25
-- Loads STI
local sti = require "sti"

-- Loads the lua file for the map (map1.lua)

function love.load()
-- Sets window size (scale = 0.5, the tiled map size is 2048 * 2048 (32 * (64 pixels large tiles))
love.window.setMode(2048*scale,2048*scale)

-- initiates the player var and gives it some properties
player = {x = 100, y = 100, img = nil, hp = 100, mp = 100}

-- Loads the image previously stated as nil
player.img = love.graphics.newImage("assets/player.png")

-- Initial state
state = "menu"

house = sti.new("map/map01")

end

function love.draw()
	house:draw()
	house:setDrawRange(5, 5, love.window.getWidth(), love.window.getHeight())
	love.graphics.draw(player.img, player.x, player.y)
end

[IGNORE THIS]{

function love.update(dt)
house:update(dt)
	if love.keyboard.isDown("i") then
		house.x = house.x + (3 * speed)
	end
end

}

function love.keypressed(key)
end

function love.resize(w, h) 
    house:resize(love.window.getWidth(), love.window.getHeight())
end

conf.lua (Allthough not very important)

Code: Select all

-- Screen Size

scale = 0.5 -- Sets the global scale (normal size * this will equal actual screensize)
	function love.conf(t) -- Hook for configurations
		t.console=true
		t.title = "RPG Test" -- Title
	end

What actually comes up when I run the file

So, what I wanna know is how to limit the map to be rendered inside the window's borders.
One would think that this would produce my wanted result.

Code: Select all

function love.resize(w, h) 
    house:resize(love.window.getWidth(), love.window.getHeight())
end

But, I digress.

Also, bonus props to those who can figure out why the [IGNORE THIS] part crashes the process.

Multi-line comments are done like this:

Code: Select all

--[[
    SOME TEXT TO COMMENT GOES HERE
]]

Here is a really short and simple game that uses both Tiled and game scaling.

I really like lua's multiline comments because you can do this too.

Code: Select all

--[[
    ...
    CODE
    ...
--]]

If you are constantly switching between using this code and not you can just remove the "[[" and it runs.

Thank you for your replies,

These unfortunately do not help solve my issue.
The source code is very large and is hard to navigate to find the specific thing I'm looking to replicate.
I'd appreciate some sort of reference, so that I know what I'm doing wrong.

Thank you again though,

Falling

Code: Select all

function love.draw()
   love.graphics.scale( scale )  -- perhaps you are missing this?
   house:draw()
   house:setDrawRange(5, 5, love.window.getWidth(), love.window.getHeight())
   love.graphics.draw(player.img, player.x, player.y)
end

This fixed it, thanks a lot!
