Thanks, I guessed that it is possible using that, but I was not sure and have not used it yet. Is the löve particle system löve-specific? Just wondering whether I can look at general particle system tutorials or löve specific ones.

As a sort of extension to this question: I have a game idea that would require lots of small pieces flying around, but physics based or pseudo physics based. Can this also be achieved using a particle system or do I need to use an actual physics engine (or at least collisions and simplified physics) for each tiny thingy?

how do you access files from the save directory (im using windows so appdata)?

if the file is inside the source folder, you just have to do is:

Code: Select all

fileLoc="(folder if theres any)/file.jpg"

but what will i do if the file is in the save directory?

You access it the same way. Files in the save folder are checked before the files in the .love our source folder.

why do i get a not exist error message when i try to load the image from the save directory?

file location: appdata/roaming/love/svdir/imageX.jpg

Code: Select all

love.filesystem.setIdentity("svdir")
src = "imageX.jpg"
image = love.graphics.newImage(src)

imageX.jpg is the only file in the svdir folder

If you're running an executable (rather than a .love file), then the file location would be Appdata/Roaming/svdir/imageX.jpg

But if not, could you post a picture of your imageX.jpg file with the location on top? And the part of the code responsible for loading it. Just to make sure there aren't any typos or anything like that...

i finally solved it tnx. i made a stupid mistake by declaring imageX before declaring love.filesystem.setIdentity("svdir"). its ok now

Does anyone know if you can have music and code run while an android screen is off? I want to make a music player, but I'm guessing that the feature would be in the code-runner itself if it exists (maybe a way to toggle it?)

Can someone tell my why the output is always printed backwards if I do this:

Code: Select all

function love.load()
	listy = {first = 1, middle = 2, last = 3}

	for i, v in pairs(listy) do
		print(i, v)
	end
end


function love.update(dt)
end


function love.draw()
end

Consoles output:
last 3
middle 2
first 1

Pairs doesn't have a defined order. If you need them to be printed in a specific order, use a sequence and ipairs. Two examples:

Code: Select all

--do this if you need textual indices in listy;
function love.load()
   listy = {first = 1, middle = 2, last = 3}
   order = {"first", "middle", "last"} 

   for i, v in ipairs(order) do
      print(v, listy[v]) 
   end
end


function love.update(dt)
end


function love.draw()
end

Code: Select all

--do this if you don't 
function love.load()
   listy = {1, 2, 3}

   for i, v in ipairs(listy) do
      print(i, v)
   end
end


function love.update(dt)
end


function love.draw()
end

@Nixola I think you meant to use 'ipairs' on the first function example, rather than 'pairs'
