ATL Transitions

[PyTom]

Not exactly a development, but rather something that's been in Ren'Py for a while: ATL Transforms. Basically, if an ATL transform takes the new_widget and old_widget properties, and sets the delay property, it can be used as a transition. For example:

For example, a transition that spins the old scene around twice, changes, and spins the new scene twice before stopping.

Code: Select all

transform spinner(new_widget, old_widget):
    delay 1.0
    xalign 0.5 yalign 0.5

    old_widget 
    rotate 0 
    linear 0.5 rotate 720
    
    new_widget
    rotate 0
    linear 0.5 rotate 720

And a transition that slides the old scene out to the right, and the new scene in to the right.

Code: Select all

transform slidebothright(new_widget, old_widget):
    delay 0.5
    
    contains:
        old_widget
        xanchor 1.0 xpos 1.0
        ease 0.5 xanchor 0.0
        
    contains:
        new_widget
        xanchor 1.0 xpos 0.0
        ease 0.5 xanchor 0.0

I have a quick question/comment about ATL transitions. I was wondering if there were still limitations from transitioning a sprite from one Z value to another Z value in - say - a Move transition using ATL Transitions? For example, when a guy moves from behind a tree to in front of the tree in one go. Will I have to draw him in front of the tree and the other fighters he passes for the whole movement, and having him pop up to his new Z at the beginning of movement or will I have to have him keep his old Z, staying behind the tree and other fighters he passes until he finishes his movement?

If there are limitations to this, are there any plans for fixing this in a release?

I don't plan to change the zorder behavior. Ren'Py is a visual novel engine, and interpolating zorder doesn't make sense in a VN.
