You have your quad:

Code: Select all

your_quad = love.graphics.newQuad(x, y, w, h, your_image:getWidth(), your_image:getHeight)
You draw your quad:

Code: Select all

love.graphics.drawq(your_image, your_quad, x, y, ...)
Note the drawq, as opposed to just draw. The q means it will draw a quad instead of just an image.

Just an example. Quite simple.

You have an array of quads with numbers referring to frames.

You have a variable that changes at the framerate you choose and loops.

You draw the quad that corresponds to the current frame.

For instance, you have a sprite sheet with all your animation frames next to each other.

You create the array of quads pseudo-ically like so:

Code: Select all

quad_array = {}
for i = 1, number_of_frames do
  quad_array[i] = love.graphics.newQuad((i - 1) * frame_width, y, frame_width, frame_height, image:getWidth(), image:getHeight())
end
Then in your update function for your animated thingy you increment the frames like so:

Code: Select all

current_frame = current_frame + dt * frame_animation_speed
if current_frame > number_frames then current_frame = 1 end
Then you draw the current quad...

Code: Select all

love.graphics.drawq(image, quad_array[math.floor(current_frame)], x, y, ...)
Or something like that. It's just pseudo.

UPDATE stuff goes in love.update(dt)

DRAW stuff goes in love.draw()
