Images?

[God Awakened]

The Wiki isn't a very strong source...

Code: Select all

function love.draw()
		function newPaddedImage(filename)
		local source = love.image.newImageData(filename)
		local w, h = source:getWidth(), source:getHeight()

		-- Find closest power-of-two.
		local wp = math.pow(2, math.ceil(math.log(w)/math.log(2)))
		local hp = math.pow(2, math.ceil(math.log(h)/math.log(2)))

		-- Only pad if needed:
		if wp ~= w or hp ~= h then
			local padded = love.image.newImageData(wp, hp)
			padded:paste(source, 0, 0)
			return love.graphics.newImage(padded)
		end

    return love.graphics.newImage(source)
	end
newPaddedImage("C:/Documents and Settings/Nanny/Desktop/Beau/JesUnlimited/Header.gif")
end

It keeps saying that it can't load the GIF file.

New:

Code: Select all

function love.draw()
		function newPaddedImage(filename)
		local source = love.image.newImageData(filename)
		local w, h = source:getWidth(), source:getHeight()

		-- Find closest power-of-two.
		local wp = math.pow(2, math.ceil(math.log(w)/math.log(2)))
		local hp = math.pow(2, math.ceil(math.log(h)/math.log(2)))

		-- Only pad if needed:
		if wp ~= w or hp ~= h then
			local padded = love.image.newImageData(wp, hp)
			padded:paste(source, 0, 0)
			return love.graphics.newImage(padded)
		end

    return love.graphics.newImage(source)
	end
newPaddedImage("HEADER.gif")
end

The problem is that the window shows, but the image doesn't.

That's not... how it works at all.

Example how it could work:

Code: Select all

function newPaddedImage(filename)
	local source = love.image.newImageData(filename)
	local w, h = source:getWidth(), source:getHeight()

	-- Find closest power-of-two.
	local wp = math.pow(2, math.ceil(math.log(w)/math.log(2)))
	local hp = math.pow(2, math.ceil(math.log(h)/math.log(2)))

	-- Only pad if needed:
	if wp ~= w or hp ~= h then
		local padded = love.image.newImageData(wp, hp)
		padded:paste(source, 0, 0)
		return love.graphics.newImage(padded)
	end

	return love.graphics.newImage(source)
end

function love.load()
	header = newPaddedImage("HEADER.gif")
end

function love.draw()
	love.graphics.draw(header, 0, 0)
end

Do you know Lua? It's pretty vital to know that for LÖVE, and not that hard to learn.

[God Awakened]

I've been programming Lua for 3 years...
O.o
And thanks.
It's just that I'm new to LOVE.

[Robin]

Oh, OK. I'm sorry I assumed you were a rookie in Lua.

Then the thing you probably didn't know is that love.draw() is called every frame, which would create a new closure every frame, and that images are objects you need to keep around and draw yourself, because LÖVE can't know what you want to draw, when you want to draw it, where you want to draw it, etc.

I'm sure you'll find the wiki most useful if you just keep on browsing. If you haven't already, you might want to check out the tutorials.

Uh... Have you not used Lua in a while, or has Lua changed some syntax here...
Last time I tried declaring a function like this:

Code: Select all

function blargh() 
    function localrand() 
        return 4; --xkcd reference ftw
    end
    print(localrand())
end

barfed errors all over my console. You should do this:

Code: Select all

function blargh() 
    localrand=function() 
        return 4; --xkcd reference ftw
    end
    print(localrand())
end

:S

It has.

Kay. I thought I might be going a little crazy.

What version of Lua are you using? It works fine in 5.1.4. Also note that in both cases "localrand" is actually a global.

Idk. I think I tested it in Lua 4.0... I had some old LuaEdit that I got from download.com...

I knew that. :S

I just left it out (AKA forgot).
