Animating Effects/Transitions

I know that LOVE supports GIF/Sprite batch techniques for animation.
Before I go off and do it myself are there any tween/ fade libraries that are written with love or are compatible?
For example. If I'm making a button/image fade in and out. or flash shift over when the mouse is hovering.
I feel like there is already a better solution for simple shift over/shift back animation.
I know it's not part of CORE GAME DESIGN ( which I'd love to talk about), But aesthetically what ways does LOVE support graphic design? Visual feedback as part of game design.

I wouldn't mind one either. Fading down and up. I've usually built my own in other languages. But am having trouble doing it in LÖVE.
I just need to get one for transitioning between maps. So I don't need some complex thing. I even use my own camera system rather than overloading my code with a separate framework.
Also, animations have been removed from the next version.

I have started
Fling, which is a library to do flash-like things in LÖVE, however it is hugely unfinished. But if you or anyone have something for Fling, you can just add it, since it belongs to the community.

Animations have been removed from the next version?
Maybe there is a way to reconstruct movieclip animations from flash. In CS3+ you can export an animation behavior to an XML file. Maybe there is a way to reconstruct those transitions. It seems kind of far off.
Is there any news around the community for people developing software with love that IS a game building tool. Something that interactive that works with TILEd or some kind of visual asset manager for game objects. Like a UI/ game state builder.
Seriously if it comes down to it I'll just be writing lua modules for a little while.
On a side note. If I want to make 'loading' Screens, or even manage large amounts of assets how do I getBytesLoaded()/total(). How does LOVE/ lua handle data on that level?

The good news: it has a replacement. bartbes wrote a Lua library (AnAL) for that purpose.

nn...I don't think that'll be easy. Lua is not so strong with XML, I think.

AFAIK, the only way to do it is to guesstimate the amount to load:
Code: Select all
dataToLoad = {{"img1.png", 23192}, {"img2.png", 46414}, {"img3.png", 94620}} --filename=size
images = {}
totaltoload = 0
for i,v in ipairs(dataToLoad) do
totaltoload = totaltoload + v[2]
end
function load()
loadingstate = 1
loaded = 0
end
function update(dt)
if loadingstate <= #dataToLoad then
images[loadingstate] = love.graphics.newImage(dataToLoad[loadingstate][1])
loaded = loaded + dataToLoad[loadingstate][2]
loadingstate = loadingstate + 1
else
--game logic here
end
end
function draw()
--do something with totaltoload and loaded
end

Thanks! This looks interesting.
For something like this I'd rather fake it anyway. It really doesn't matter to me or the player exactly what percentage is loading. I'm pretty sure I can use this to fake it.
Do you know when the next version is supposed to come along?

I know the standard C way is seeking to the end and using tell to get the position, however I do know PhysFS has a length function.

I seem to remember that LOVE supports additive blending. Could you use that for highlighting buttons or somesuch?

Definitely. I'm going to use color definitions with the alpha changing over time.
like.
full = 255
color [Black] (0,0,0,opa)
while opa < full
opa +=5
end
When it comes to handling time with love do I want to just get the difference between the os Time ? Is there a faster way to get a millisecond clock?

Do you mean the dt variable?
