Film loops and rotation

Question

I have a character that is seen from the top and I can move
and rotate it - as long as it is a single image. However, I've put
together a 4 frame film loop and the film loop won't rotate. Is
there any way to do that - rotate a film loop? Can I get at the
sprites in the film loop instead? I can use an animated gif but the
line quality is a bit rubbish. Would a small linked movie be
controllable? Any other suggestions?
Thanks

Answer 1

You can get access to any of the loop's sprites through the
loop-sprite's movie property. Assuming you used sprite channel 1
for your 4 frame loop, then the following behavior will rotate
those sprites inside the film loop.
property pMovieSprite
on beginSprite me
pMovieSprite = sprite(me.spriteNum).movie.sprite(1)
end
on enterframe me
pMovieSprite.rotation = pMovieSprite.rotation + 10
end
In the property inspector select the "Film Loop" tab for your
film loop member and select the "Crop" and "Center" radio buttons.
This will enable you to resize the film loop sprite to fix any
cropping issues.
Note: This will also work for LDMs - Linked Director Movies,
if you want to use these "Loops" across multiple movies.
