yes flv "flash" kind of works but not good at all, the colors get weird and speed is funky
sprites take some work aligning, but work great
here is some code to help you out
local joystick = fe.add_image("joystick-move.png", flx*0.050, fly*0.050, flw*0.80, flh*0.80 );
local sprite_cfg = {
when = When.Always,
width = 80,
frame = 0,
time = 3000,
order = [ 0, 1, 0, 2, 0, 2, 0, 1 ],
loop = true
}
animation.add( SpriteAnimation(joystick, sprite_cfg ) );
