Adding an AlphaMask to a Character Sprite? [Solved]

[Katy133]

I just got to play through this, Thanks Katy133. I learned a lot!
I feel like I still need to learn more about AlphaMasks, when you use them, the various things you can do with them, that sort of thing. But this is a great start!
Thanks!

ETA: Katy133...actually I have a request...which you can ignore!

Do you think you could update your cookbook recipe to explain other uses of AlphaMask and what a person would do with AlphaDissolve? I feel like these tools must be very useful, but I don't really understand when you'd want to use them or what that would look like.

I've started looking into it, and I think it's beyond my level of coding at the moment. But I was able to find an example of it in Ren'Py's Tutorial game. It's under Transition Gallery --> AlphaDissolve in the game. The example used was animating a Looney Tunes-style iris dissolve, but I've not really sure how to edit it.

In the tutorial, it describes this:

Code: Select all

image alpha_control:
    "spotlight.png"

    anchor (.5, .5)

    parallel:
        zoom 0
        linear .5 zoom .75
        pause 2
        linear 1.0 zoom 4.0

    parallel:
        xpos 0.0 ypos .6
        linear 1.5 xpos 1.0
        linear 1.0 xpos .5 ypos .2

    pause .5
    repeat

define alpha_example = AlphaDissolve("alpha_control", delay=3.5)

    scene bg washington
    show eileen happy at center
    with alpha_example
 

Hope this helps--even a little bit!
