Here is a link to a code viewer with my program in it.

This program overall is still kinda confusing to me. Specifically the activeFrame and currentFrame variables and the love.update(dt) function. Both of which I got from another source on animation in LOVE. But anyhow I'm trying to get the program in LOVE to alternate between the first animation frame and the second animation frame. Both sprites are currently positioned on top of each other when running the program.

I can see what's causing you problems.
I suggest eliminating 'activeFrame' and stick with 'currentFrame'.
Then love.draw only has to contain

Code: Select all

im = animations[currentFrame]
love.graphics.draw(im, love.graphics:getWidth()/2,love.graphics:getHeight()/2, 0, 0.2,0.2 ,im:getWidth()/2,im:getHeight()/2)
Think I've got that right.

That works thank you! But how would I separate both draw functions? I want to change the individual parameters for each image, for example their respective scaling. Is there a way to modify my existing two draw functions to allow for that? I tried replacing the animations[1] key with the variable im that you listed above but instead of drawing a single image it draws a duplicate for each image per frame.

Tables are what you want.

Code: Select all

ans = {
	{
	image = love.graphics.newImage('somethingOne.png,
	x=100,
	y=100,
	sx = 0.2,
	sy = 0.2
	},
	{
	image=love.graphics.newImage(somethingTwo.png',
	x=300,
	y=100,
	sx=0.3,
	sy=0.3
	}
	}
and then love.draw() contains:

Code: Select all

love.graphics.draw(
	ans[currentFrame].image,
	ans[currentFrame].x,
	ans[currentFrame].y,
	0,
	ans[currentFrame].sx,
	ans[currentFrame].sy,
	ans[currentFrame].image:getWidth()/2,
	ans[currentFrame].image:getHeight()/2
	)
