ATL flickering when transitions are used?

[Rinzamakani]

Hello. I've been trying to animate fog for my game using two png images. However, when I use the "with dissolve" command with each image in the ATL block, the frames flicker to black whether it be for a single frame or the black just takes up the entire screen once starting the game. At first, I thought it was my images that I probably had drawn on by accident, yet that doesn't seem to be the case. Both images are indeed transparent. This does NOT happen when I remove the dissolve commands. However, the fog doesn't work the way I'd like it to without the dissolves.

Here's the code I've been using.

Code: Select all

image fog:
   "Fog1.png" with dissolve
   0.50
   "Fog2.png" with dissolve
   0.50
   Repeat

And here's where I actually use the code.

Code: Select all

Scene room6 with dissolve
Show fog
Show tv with dissolve
Show snow

I find this odd since the other image I've animated with ATL works smoothly. In case it matters, I'm using Renpy version 6.99.13.2919

This seems to be a limitation with an animated image using something like dissolve for the individual images in the animation.

The transparent color will show up as black (except for the first image where transparency will work).

One thing you could do is to use a graphic editor to create more images with a different mixes between the two images. That way you could create a similar effect without using dissolve.

You can also try this:

Code: Select all

image fog:
   "Fog1.png" with Dissolve(0.5, alpha = True)
   0.50
   "Fog2.png" with Dissolve(0.5, alpha = True)
   0.50
   Repeat

   0.50
   Repeat

Obviously a better way

I did not realize that could work. In the manual the alpha argument is described as "ignored" which seems a bit misleading.

This worked. Thanks a bunch!
