need help with sprite animation

[zeroxskater]

hey everyone well im developing a game, and i need to redo a couple of things before i get to far into the game. the biggest thing is sprite animation.

i have been using a code that is a timer and when a timer his a certain time it changes the image but that takes up alot of code and is inefficient. i have been looking for tutorials on this but had no luck, so can someone point me in the right direction?

[lua scripter]

blue = Color.new(0,0,255) 

player = Image.createEmpty(32,32)
player:clear(blue)

Player = { x = 30, y = 100 }

function movePlayer()
pad = Controls.read()
if pad:right() then
Player.y = Player.y + 5
end
if pad:left() then
Player.y = Player.y - 5
end
if pad:down() then
Player.x = Player.x + 5
end
if pad:up() then
Player.x = Player.x - 5
end
end


while true do 

screen:clear()

movePlayer()

screen:blit(Player.y,Player.x,player)

screen.waitVblankStart()
screen.flip()
end

if you want to get your won image you need this code at the top of this code were player=
heres the code

player=Image.load("were you image is located")
