Oh, shit, I forgot to warn you against that method. It is evil, please don't use it. It runs "game.lua" every time you start a new game.
is much better. You will want game.lua to provide a function that sets things up in that case. You then call that function when the player starts a new game.
ntpspe wrote:@Robin yeah, Well I've managed to get button detection working by creating 4 variables, x1, x2, y1 and y2, which set the boundary for the 200x100 button.
Exactly.
If you want more buttons, it might be an idea to use tables to avoid code duplication.

Don't worry, i'm using:
Code: Select all
function love.load()
newgame = love.filesystem.load("newgame.lua")
end
[ALL the rest of the code for buttons and that]
function startanewgame()
newgame()
end
So that when the user clicks my newgame button, it runs "startanewgame" which then loads "newgame" from the newgame.lua which is working perfectly, and it loads the lua file at the start ready, but only executes it when called.

Yeah, I was thinking tables would be handy, what do you mean by code duplication though?
Personally I'd prefer to manually code the co-ordinates of each button and the checks for them, it might not be efficient, but it works

you can do:

-- check for button i
end
Much better, isn't it?

This might seem easier now, but it will bite you in the end.

Yeah, but isn't that why we load all the images in [love.load()] and then draw them elsewhere, rather than loading them at every function that needs them? I thought the same principle would apply for loading all the rest of the files and setting default variables.
And nice 200 line example! Haha yeah... it might end up biting me later ¬_¬ I'll work on it

If you call newImage, newFont or things like that in newgame.lua, they will be loaded every time you start a new game, instead of just once.

Ah I see. But I want 'newgame.lua' to be loaded every time the game is loaded don't I?
Also, on a side note, whenever I use [love.graphics.newFont] (and by whenever I mean it was placed in love.load() to load the font I wanted at the start of the game, but I also tried it elsewhere) The fps drops to 3 and my ram starts climbing slowly, to the point where the system crashes. (memoryleak?)
And it's not because I'm loading a font, even just changing the size of the default font caused the same problem :/
Code: Select all
love.load()
font = love.graphics.newFont(20)
love.graphics.setFont(font)
end
love.draw()
love.graphics.print("Some text", 100, 100)
end

Hm, we might be thinking about two different things.
- User starts game
- Game loads
- Menu
- User selects "new game"
- New game starts
- User plays game
- Back to menu after game over or user quitting
- User selects "new game"
- New game starts
- User plays game
- Back to menu after game over or user quitting
- User selects "new game"
- New game starts
- ...
The method you're using does all those things (loading images, things like that) at the bullet points that say "New game starts". What I'm saying is that you only need to do that at the point that says "Game loads".

I've never seen that before. Could you post details about your system (operating system, graphics card, things like that), so the devs might be able to do something about that?
What happens if you run games other people made (there are quite a lot little games and demos on the forums)?

Oh I understand now
As for the problem, I think I accidentally made some kind of loop that was repeatedly setting the font to size 20, which must have been using up the system resources or something, I'm not sure, but I ended up replacing my text with images anyway, and just using the default font for anything else.
(It was late at night so probably made a mistake haha. There's a screenshot up on ntpspe.wordpress.com with the system monitor showing the graph peaking at 80% ram usage)
