Playing animations

[LuaWeaver]

Is there any way to program a .gif or .avi to play in Love?

Also, on a side note, anyway to compress a .gif animation so I can upload it here?

Love doesn't support either of those. You could export the frames as .jpegs and flip through them if it's a short animation, though (I assume it is since you're talking about .gif).

As for making animated .gifs, I normally use VirtualDub. It's a light video processing tool, and can export to .gif.

You could use each frame of the .gif as the animation like this:

Code: Select all

function love.load() 
	frame1 = love.graphics.newImage("x.png") 
	frame2 = love.graphics.newImage("y.png")
end 



function love.update(TimeInSeconds) 
	if TimeInSeconds == 1 then 
		love.graphics.draw(frame1, xpos, ypos) 
	elseif TimeInSeconds == 2 then 
		love.graphics.draw(frame2, xpos, ypos) 
		TimeInSeconds = 0 
	end 
end 
	

My apologies for icky or invalid code. Still kinda new at this. There's also probably a better way to reset TimeInSeconds.

the value passed to love.update is actually the time since the last frame: so while it is in seconds, it is usually very low (0.016 for 60fps)
so if, for example, you wanted something to occur roughly every second, you would do something like:

Code: Select all

local timer = 0
local interval = 1

function love.update(dt)
	timer = timer + dt
	if timer > 1 then
		timer = timer -interval
		--do stuff
	end
end

EDIT:
Also note that the screen is cleared between love.update and love.draw, so any draws inside love.update wont show.

What's also often done is placing all the frames of an animation on a single image, and using a quad that changes its viewport to animate.

*.avi will not work without video support, so no way.
*.gif animation will not work directly, you will need to convert it to the series of frames. Beware, optimized animated gif is not just a sequence of frames - it can depend on the previous frame's content. Check this out for decompositing the animation:

How has no one mentioned AnAL yet?

Because OP asked about *.avi movies or *.gif animations, none of which are directly supported by AnAL?

But AnAL does do the next best thing. Why force a confused newcomer to write their own animation system when we already have one that works?

Thanks guys.
