Transitioning to an ATL-animated background with a dissolve?

[Nova Alamak]

I've got a working animated background made with ATL but when I "scene" or "show" it with a transition (just trying basic dissolve in this case) it doesn't work? It just shows without a transition. Is there any way around this?

Add the transition to the ATL itself.
If you have to, make a dupe - one with the transition, one without

How do I do that? I tried using "on show" but that didn't work. It makes the whole image vanish...

[Imperf3kt]

No, I meant add the dissolve into the ATL:

Code: Select all

image atl example:
     # Display logo_base.png
     "logo_base.png"

     # Pause for 1.0 seconds.
     1.0

     # Show logo_bw.png, with a dissolve.
     "logo_bw.png" with Dissolve(0.5, alpha=True)

     # Run the move_right tranform.
     move_right

There's also:

Code: Select all

show logo base:
    on show:
        alpha 0.0
        linear .5 alpha 1.0
    on hide:
        linear .5 alpha 0.0

Currently, the first example is something like what I have. The problem is that when it is shown, the opening transition does not show. The image is just shown instantly despite the code. If I use the second example, I just get a blank screen...

To help further, you'll have to share the code you're using.

in init:

Code: Select all

image bg westgate:
        on show:
            linear 1.0 alpha 1.0
        0.25
        "bg/WestGateDay1.png"
        0.25
        "bg/WestGateDay2.png"
        0.25
        "bg/WestGateDay3.png"
        repeat

in main script:

Code: Select all

scene bg westgate

If I take out on show section it works, but doesn't have a transition. If I leave it in, I get a blank transparent background. Also, I had alpha 0.0 in the code initially, but that just made it fade in FROM a blank background which jarringly replaces everything on screen for a split second. I have also tried putting a simple "with" clause on the end of the show statement to try to force a transition, but that just gets ignored by the code.

Code: Select all

image bg westgate:
    "bg/WestGateDay1.png"
    parallel:
        alpha 0.0
        linear 1.0 alpha 1.0
    parallel:
        0.25
        "bg/WestGateDay2.png"
        0.25
        "bg/WestGateDay3.png"
        0.25
        "bg/WestGateDay1.png"
        repeat

label start:
    show westgate
    "This is Westgate."

    return

But simple ATL and transition should work just fine, though.

Code: Select all

image bg westgate:
    "bg/WestGateDay1.png"
    0.25
    "bg/WestGateDay2.png"
    0.25
    "bg/WestGateDay3.png"
    0.25
    repeat

label start:
    show westgate with Dissolve(1.0)
    "This is Westgate."

    return

Oh! Parallels, of course! I'll go try that. Thank you very much for the help!

Update the code, which allow show and hide properly:

Code: Select all

image bg westgate:
    "bg/WestGateDay1.png"
    parallel:
        on show:
            alpha 0.0
            linear 1.0 alpha 1.0
        on hide:
            alpha 1.0
            linear 1.0 alpha 0.0
    parallel:
        0.25
        "bg/WestGateDay2.png"
        0.25
        "bg/WestGateDay3.png"
        0.25
        "bg/WestGateDay1.png"
        repeat

I tried that code just now, it produces the same problem. The background changes to a transparent default renpy checker-tile placeholder, then fades in to the animation from that. I tried removing the first instance of alpha 0.0 to fix that, and it DID remove the initial transparency, but then the other problem happened again: there's just no dissolve whatsoever. I've tried appending a dissolve on the ends of the images themselves in the ATL AND out of it, and it always ignores a transition if it's at the beginning of an ATL, either in the block or outside of it in the script. I'm running out of ideas.

EDIT: I think I forgot to mention, but I'm showing the background with "scene" instead of "show" because I need to clear the screen.

I have no issue with dissolve transition at all in a new project with following:

Code: Select all

image bg westgate:
    "bg/WestGateDay1.png"
    0.25
    "bg/WestGateDay2.png"
    0.25
    "bg/WestGateDay3.png"
    0.25
    repeat

label start:
    scene bg westgate with Dissolve(1.0)
    "This is Westgate."

    return

Also, you don't have to fear the transparent checker. It only appears in developer mode. In build distributions, it will be black screen. If you so concern, you can just add black background to the ATL before the "alpha 0.0". You can't remove alpha 0.0 because it is the starting point of having the background image to be invisible before fading in from alpha 0.0 to alpha 1.0.

If both of these still doesn't work, it's time you show us the code you have an issue with. So we can start to pinpoint the problem at the source.

Are you sure about it only appearing in developer mode and not builds? Because I still get it in builds.
For example, this is a a build I put together for the artist/commissioner two days ago.

No, I'm not sure about that. Just quote from the post I see recently. Actually, I remember seeing those checker background from back when in actual build, so yes, it may not actually going away.

Just put black over it before the background.

[Nova Alamak]

Are you saying to add a black bg to the ATL or to show it in the script before the image? (That won't work in this example anyway since it's shown with a scene statement...)
