okay, something is wrong with my animation, it made the character transparent but not the bg, is it something wrong with the webm format? because when i exported it as gif it was fine, when i converted it, it switched the hole thing

Did you also export a mask movie?

Tried my project, built with 6.99.10, on a friend's new Windows 10 laptop and the looping animation is freezing after a few seconds.

Red channel of the mask movie is used as alpha channel for the main movie. The only more or less passable scenario where you can use the same movie for both is a really "reddish" movie on a black background. Like an intense campfire in night time... it will still prolly not be "perfect" but it might be ok.

found one free and it has almost everything AE offers, the only problem is how hard it is to use.

There's no way to make it stop looping. Basically, if the looping stopped, the movie would no longer be playing and the sprite would go away.

The movie will go away just as PyTom said but you can edit the code a little bit to specify the amount of loops you want before that happens.

Looping was unacceptable for our project because we use complex conditioned animation sequences and we had to make sure that movie stopped after x amount of loops, so I've edited the class a bit to take amount of loops you want as an argument:

Code: Select all

    class MovieLooped(renpy.display.video.Movie):
        """Play Movie Sprites without loops. Until Ren'Py permits that by default, this can be used.
        """
        def __init__(self, *args, **kwargs):
            super(MovieLooped, self).__init__(*args, **kwargs)
            self.loops = kwargs.get("loops", 1)
            
        def play(self, old):
            if old is None:
                old_play = None
            else:
                old_play = old._play
    
            if self._play != old_play:
                if self._play:
                    renpy.audio.music.play([self._play]*self.loops, channel=self.channel, loop=False, synchro_start=True)
    
                    if self.mask:
                        renpy.audio.music.play([self.mask]*self.loops, channel=self.mask_channel, loop=False, synchro_start=True)
    
                else:
                    renpy.audio.music.stop(channel=self.channel)
    
                    if self.mask:
                        renpy.audio.music.stop(channel=self.mask_channel)
This worked really well for us so far. You simply copy/paste this to init python add amount of loops that you want as extra argument:

Code: Select all

image north = MovieLooped(channel="main_gfx_attacks", loops=2, play="content/gfx/be/webm/air/north/movie.webm", mask="content/gfx/be/webm/air/north/mask.webm")
You can replay the movie by hiding/showing the image as many times as you want, it works exactly as you'd expect.

=========>>>
You can also ATL it, showing the movie, pausing for the duration*x loops and switching to Null() but that worked less reliably and it sometimes went on for a couple more frames that it was supposed to... the above hasn't crapped out once so far and we're using them quite a bit.

I've been trying this out for the last two days so I thought I'd ask now, haha.

Does Movie Sprites only support .webm? While I can get .mpg videos to play, the mask doesn't appear to work (and it is a different file). I'm actually trying to implement it for effects like little floating embers and such playing on loop.

Code: Select all

#######ANIMATED SCENIC EFFECTS:

    image movie = Movie(channel="movie", play="Embers_CO.mpg", mask="Embers_Al.mpg", size=(1920, 1080),  xpos=0, ypos=0, xanchor=0, yanchor=0)  
Has been defined in init before the start label and:

Code: Select all

    show movie with dissolve
is in the script following.

I've tried it with .avi, but .avi, even though supported I think, doesn't play or show at all. Of course, if Movie sprites only work for .webm then I guess this makes sense.

I'm also curious as to if there's a way to implement playing movies without the mask -- .avi, .mpg, .mov, as well as .mp4 all have the capability to export alpha channels and when dropped into AfterEffects they work as such. Or if I can support in some way to getting that implemented (I really want animated effects, but so far they produce 375 images which will take ages to define and I imagine would drive up the RAM use quite a bit).

Is there a way to ensure that the current loop of a movie sprite finishes before another movie sprite is shown?
I'm hoping to ensure continuity and prevent sudden jumps in a sequence of movie sprites.

I figure that it may be done through the play_callback function but I'm not sure where to start. (I didn't find much by Googling)

I've been trying to get movie sprites to work for a project of mine. I used the ffmpeg method to turn pngs into webm with a mask. It works, but for some reason occasionally the mask fails and a black box appears behind the character for a moment. I'm not sure if it's an issue with my computer or if it's because I'm using 1920x1080 instead of a smaller scale or something else. Does anyone have a suggestion on where I should start to try potentially solving this? Oh, and my renpy is up to date.

Here's how it is usually-

And here's the error-
