Fling: a library

[Robin]

I was recently thinking about a LÖVE plug-in for Firefox. I decided that it is something that could be done, but not by me. However, that got me thinking about Flash (because, well, I don't really need to explain that, do I?), and thus was Fling born: a FLash INspired Graphics library. It's still in it's infancy, so it might change radically, and you can't do a lot with it (run the .love file to see what is).

I think the LPCL is appropriate here.

See latest post for new version.

Interesting, this way of scripting the animation once, and letting the engine doing the rest. I'm not sure how interactive this can be made. More for cutscenes or something like that perhaps?

I really like this idea. Sometimes you just want a scripted animation in your menus that don't necessarily need to be adaptable to anything.

That looks great, though you might want to move

Code: Select all

update = fling.update
draw = fling.draw

out of fling, and into the main.lua. Another thing, is there a way to draw a single animated image? Like fling.draw(img1)?

Why? I added those two lines so it would use fling.update() and fling.draw() if no update() and draw() were defined. That way, any .love using Fling would be an animation by default, unless they added some interactive code by themselves.

For the record, fling.update() and fling.draw() can be used for animating cutscenes and the like:

Code: Select all

function update(dt)
    if cutscene then
        fling.update(dt)
        if #fling.queue == 0 then cutscene = false end
    else
        -- all the usual stuff
        if x > 100 then
            -- prepare cutscene
            cutscene = true
        end
    end
end
function draw(dt)
    if cutscene then
        fling.draw()
    else
        -- draw the usual
    end
end

Good idea. I'll start implementing it right away.

I'm not sure how interactive this can be made.

Me neither. But we'll find out along the way.

I library like this needs easing in the motion.
like so: jQuery Easing Plugin (version 1.3)

Interesting... I think you're right. I will try to implement it.

By the way, I found this page very useful, and the pdf link in particular.

Whoa, definitely bookmarking that.

EDIT: Don't forget to check out the jQuery Easing v1.3 source.
EDIT2: That pdf was an interesting read. Almost makes it look easy. The author's humor was also appreciated by me.

looks very nice robin. exactly what i had in mind as well when i made a thread. i dont have the know how to do it though :p

New version!

I've implemented fling.draw(img1), started with callbacks (for example a function will be called if a certain key is pressed), and the easing functions.

Especially with the last I'm having some difficulties. I think it might be due to the way I implemented the rest of Fling.
