Ren'Py 6.17.0 Prerelease (RAPT is now part of Ren'Py)

[PyTom]

This is a pre-release. Please download and test this release - both positive and negative reports are helpful. But don't release a game until this version of Ren'Py is official.

As we reach the tenth anniversary of the start of Ren'Py development, I'm pleased to announce Ren'Py 6.17 "In This Decade...". Major improvements in this release include:

• A rewrite of the Style system that should improve Ren'Py's performance.
• A new style statement that makes it easier to define styles.
• A new "show layer" statement that makes it convenient to apply transforms and ATL transforms to entire layers at once.
• Several other syntax improvements.
• French and Russian translations.
• The integration of RAPT (the Ren'Py Android Packaging Tool) with the Ren'Py SDK. Ren'Py now downloads RAPT using the Ren'Py updater - it's no longer necessary to download RAPT separately.

This release also includes several other new functions and actions, and a pair of major bugfixes that affect the Android platform.

This release has been brought to you by:

• CensoredUsername (C)
• kyouryuukunn
• Daniel Luque

Thanks for your effort.
It looks there's an incompatible change in screens.
in 6.16,

Code: Select all

frame area(0,0,100,100) align (.5,.5)

shows the frame at the center of the screen.
But in 6.17, it's shown on the top-left of the screen ignoring align property.

[PyTom]

Isn't that undefined behavior?

Area and align are both ways of specifying the position of a displayable. You're giving them both at the same time, with conflicting information. I'm pretty sure that even in older Ren'Pys, the order in which they'd be applied was undefined.

[nyaatrap]

Yeah, though area + align is useful. for example,

Code: Select all

  frame:
                style_group "pref"
                has vbox
                label _("Sound Volume")
                fixed  area (0,0,195,20) xalign 1.0:
                    add Frame("gui/bar_disabled.png", 12,6)
                    bar value Preference("sound volume"):

(0,0,195,20) is a size of "gui/bar_disabled.png", and bar background is set to None.
This allow to use transparent thumb over the bar background. If slider bars are defined by the default way, transparent thumbs couldn't be shown neatly.
I'm using this syntax from 6.14

edit: area (0,0,195,20) can be written as minimum (195,20) maximum (195,20), But it's redundant so I used area instead.

[PyTom]

How about I add xsize, ysize, and xysize properties? (size is a name I use already, so I can't use it again.)

[nyaatrap]

Yes, they are what I want. Thanks again.
I also find a minor bug. When I press about on the launcher, it shows an error; couldn't find a file "logo.png"

[jack_norton]

The new style syntax is awesome will use this version in the new games testing!

[nyaatrap]

Performance is improved noticeably, though the hover function is still unusually slow. I suspect there is something wrong on this function.

[Donmai]

OMG! "Happy Alley" is gone, at last! Hahaha! Finally I won't need to mute the sound when playing the tutorial game anymore!

Can you give me some code that shows the slowdown? I need examples to help me debug it.

Sunflower Slow Drag was actually the song that played in the background of the original demo - back when Ren'Py supported midi files. I brought it back for the tenth anniversary as much as anything. If it's less exposed than Happy Alley, all the better.

Some issues:
1. While creating new project, if language set to russian in preferences, an error appears when it comes to choose a theme (seems that with other languages all works fine)

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/new_project.rpy", line 123, in script call

Ren'Py Launcher 6.17.0.239

2. While creating new project, if no template chosen an error appears (similar issue was fixed with choosing distros to build).

3. And not a bug, but just a thought - it is possible to run a project or a launcher (of the same version) multiple times at once, could it be changed, so just one copy of a project / launcher would be opened?

[Kinsman]

In skin.rpy, the constant PATTERN is set to "pattern.png" when it should be "images/pattern.png".

Also, in about.rpy, the about screen needs to refer to "images/logo.png" instead of "logo.png".

[Kinsman]

Definitely like the new style coding. It really is a lot easier to work with.

Could you make sure that the new style code is used in the options.rpy file of new projects?

[PyTom]

Alex:

1 & 2 will be fixed in the next pre-release. 3 is an interesting idea, but it's enough of a change that it won't land in 6.17.

Kinsman:

We don't ship skin.rpy with Ren'Py. You'll have to update it.

about.rpy has been fixed.

[nyaatrap]

Can you give me some code that shows the slowdown? I need examples to help me debug it.

Sure.

Code: Select all

# The game starts here.
label start:    
    call screen hover_test
    return
    
screen hover_test:
    default tt=Tooltip("")
    grid 16 16 align (.5,.5):
        for i in range(256):
            textbutton "[i]" action NullAction() hovered tt.Action(str(i))
    text tt.value align (.5,1.0)

I exaggerated the issue using 256 buttons. Though even 20 hover buttons have noticeable slow down.
