Ren'Py Flipping a character

[astare]

In ren'py I used xzoom -1 to flip the image. It works OK but now I have encounterd a problem. When using the following code:

show alice at left with Dissolve
alice "says sth"
show alice at left with Dissolve:
xzoom -1

the image does not appear flipped.

What am I doing wrong?

The "at" part of "at left" is the "apply transform operator". Transforms are bits of renpy code that can modify displayables. And then on the resulting displayable a "with" will apply a "transition".

To get your "alice" displayable flipped AND on the left, you need to first define a "flipped" transform outside of the label scope, and then combine the two transforms on your show statement.

# define the transform
transform flipped:
    xzoom -1

label start:
    scene bg washington
    window show
    show eileen vhappy

    # this is using the built-in transition "dissolve"
    e "Hi! My name is Eileen, and I'd like to welcome you to the Ren'Py tutorial."
    show eileen happy with dissolve

    # this is a built in transform "left",  and uses the "Dissolve(time)" class for a user-defined transition time
    e " now i'm gonna go left"
    show eileen happy at left with Dissolve(1.0)

    # note that this transform does not reset the previous position transform, just applies the additional xzoom
    e " now i'm gonna flip"
    show eileen happy at flipped with Dissolve(2.0)

    # you can then combine multiple transforms with commas after the "at"
    e " now i'm gonna go right flipped"
    show eileen happy at right, flipped with Dissolve(3.0)

Also, the way you used "with Dissolve" is not correct. "dissolve" (small d) is the built-in transition that has a 0.5 second effect time. If you use "Dissolve" it is calling the underlying class and that requires the parentheses and the required "time" parameter to make it a proper function call.
