RPG-style walking animations with AnAL

[maage]

Admittedly, I'm new to love2D (but certainly not to programming). I'm struggling to understand how I can get AnAL to read a sprite sheet and change the character direction based off the key pressed. That is, I want it to be like a Zelda or RPG style walking system where the character's sprite changes based on direction according to user input.

This is the code that I have so far:

Code: Select all

require("AnAL")

SPRITE_WIDTH = 32
SPRITE_HEIGHT = 48

function love.load()	
	img = love.graphics.newImage("sprites/chikaru.png")
	spr = newAnimation(img, SPRITE_WIDTH, SPRITE_HEIGHT, 0.2, 0)
	spr:seek(3)
end

function love.update(dt)

	if love.keyboard.isDown("left") then
		spr:seek(3)
		x = x - 100
		spr:update(dt)
	end
    if love.keyboard.isDown("right") then
		spr:seek(7)
    	x = x + 100
		spr:update(dt)
	end
    if love.keyboard.isDown("up") then
		spr:seek(11)
    	y = y - 100
		spr.update(dt)
	end
    
	if love.keyboard.isDown("down") then
		spr.seek(15)
		y = y + 100
		spr.update(dt)
    end

end

function love.draw()
	love.graphics.draw(spr, x, y)
end

What am I doing wrong? Is there a tutorial someone can point me towards? I feel pretty lost, I've just been looking at other people's source code and trying to figure out what they did.

Create a variable that is updated on input and draw the animations from that. It's no different than changing the image displayed based on keypress.

You mix

Code: Select all

spr:update(dt)

with

Code: Select all

spr.update(dt)

They mean different things. I think the first one is the one you want, if you call spr.update(dt), the function "update" cannot know what sprite (in this case spr) you are talking about and that seems wrong.
