Hmm, sorry I would prefer not to use the canvas, I hear it has issues and I want to work with the (primary?) buffer.
I guess I'll have to render it the old fashion way and append all my drawables to a list to be rendered in a virtual rect which is scaled using.. math.

What kind of issues did you hear?

For my game I use canvases extensively and haven't had any issues at all, nor have I heard of anyone else having any. If there are issues they must be fairly small and only in edge cases. Doing everything a canvas has to offer using math sounds horrible and like a lot of extra work!

Canvas has no issues. Especially on 0.10.0 where it is guaranteed to work since it doesn't run on machines that don't have support anyway.

Use them.

Hey guys, I was testing love.filesystem.remove, and something kinda weird was happening to me: it never actually deleted a file the fisrt time the love.filesystem.remove command was called in the game. Only when I called it a second time (or anytime later) it actually worked. To prevent this from happening, I wrote the command twice, as the game goes on even if no file was found or deleted. But do you have any ideas why that was happening? o.O

Can you write a minimal example that people can test?

Also was the file inside the save directory? LÖVE can't delete files that are not in the save directory

Yes, it was in the save directory.

Yes

This is the function that deletes the deck file (it is a card game). This file extension is specific for the decks, but they are just .txt
'deckList' is a table with the names of each deck.
'deck' is the index of the currently selected deck.
'deckDir' is just a string used by other functions in the same file, referring to where the decks should be saved. I kept it in a variable so I could change it later if necessary. (for now, it's just a folder called 'decks')

Code: Select all

function deckDelete(deck,deckList)
    if deckList[deck] then
        love.filesystem.remove(deckDir .. '/' .. deckList[deck] .. '.dhcd')
        love.filesystem.remove(deckDir .. '/' .. deckList[deck] .. '.dhcd')
        table.remove(deckList,deck)
    end
    return deckList
end

Edit: the deckList table is made when the game loads, according to the files inside that deckDir folder.
So, for example, if the 'deck' variable was 3 and the deckList table contains 15 strings that correspond to the files inside the deckDir folder, deckList[deck] will be, in this case, the third deck, ('test deck (3)' for example). The line should become:

Code: Select all

love.filesystem.remove('decks/test deck (3).dhcd')

It seems there's nothing wrong with it, and indeed there isn't, but somehow, only during the first time this command is run, nothing happens.

That example is not enough, those functions work if used like that, please provide a .love file that actually shows what the error is

[PiFace]

... well, nevermind, after making a window to confirm the deletion (those "Are you sure you want to do this?" popups) it just works as intended. Sorry to bother .-.

Yeah, now that I come to think of it, the problem could not be inside that function, it was somewhere else, but now that it's gone, I think it doesn't matter anymore.
