Snow Plugin

[mikedee]

Just in time for christmas :)

This thread is really just a restart of this thread

http://forum.go-compiz.org/viewtopic.php?t=169

This version is from version 1744. I have included the coz's_BerylFlakes directory (it is copied to your ~/.compiz/images directory). I have renamed them and put them in one directory. The new names roughly reflect the original directory.

In theory it would be possible to modify this so that it can load svg's as well (if you have the svg plugin), but that would depend on a git version of compiz, so I havent done it for now.

Plugin originally from corner on beryl.

Hi mikedee,
I get this error:
compiling : snow.c -> build/libsnow.losnow.c:166: error: expected specifier-qualifier-list before 'DrawWindowProc'
snow.c: In function 'stepSnowPositions':
snow.c:211: error: 'SnowScreen' has no member named 'allSnowFlakes'

[mikedee]

Thats a strange error, its probably related to your gcc version.

I have just uploaded a slightly different version, can you try again and let me know if it works.

[mcz]

Thank you,

but I get always the same error:

The same error is also in the
Ubuntu Forum (http://forum.ubuntu-it.org/index.php?topic=51095.msg281332#msg281332)

[Haisen]

Same error on openSUSE 10.2.

[mikedee]

I can reproduce the error on my Ubuntu box now, Ill see if I can fix it.

[mikedee]

Try now :)

[mcz]

Thank you mikedee,

now the plugin compile, but I can't see any snow.
I put the plugin before 'cube' but nothing happens.
I tried with F3 and super+F3 but nothing.

[watkin5]

snow is mainly working for me, except that i've got squares not flakes
[Snow]: Texture not found : /home/watkin5/.compiz/imagessnowflake2.png

i copied and renamed all the snowflake images and now get[Snow]: Loaded Texture /home/watkin5/.compiz/imagessnowflake2.png

but, i still get squares not flakes.
[please excuse my case, but my shift key isn't working.]

[mikedee]

Try entering the snowflake images like this

/home/watkin5/.compiz/images/snowflake_1.png
/home/watkin5/.compiz/images/snowflake_2.png

The snowflake2.png is an old file, there should be lots in your ~/.compiz/images folder.

[watkin5]

I entered the images as you suggested into
/apps/compiz/plugins/snow/allscreens/options/snow_textures
and
it's snowing :D

compiz is still complaining though;[Snow]: Texture not found : /home/boberty/.compiz/imagessnowflake2.png
[Snow]: Loaded Texture /home/boberty/.compiz/images/snowflake_0.png
[Snow]: Loaded Texture /home/boberty/.compiz/images/snowflake_1.png

Thanks for you help, and the port.

[mikedee]

compiz is still complaining though;[Snow]: Texture not found : /home/boberty/.compiz/imagessnowflake2.png
[Snow]: Loaded Texture /home/boberty/.compiz/images/snowflake_0.png
[Snow]: Loaded Texture /home/boberty/.compiz/images/snowflake_1.png

Try not to think of this as complaining, its more a helpful developer letting you know whats happening :).

If you still have /home/boberty/.compiz/imagessnowflake2.png in the images config then remove that one and it should be OK.

[mcz]

Sorry mikedee,

now the plugin works.
But not with the wallpaper plugin.
It's possible to make the snow working also with the wallpaper plugin (without kdesktop)?
[/i]

[watkin5]

But not with the wallpaper plugin.

It works with wallpaper for me if I tick, in gconf-editor;
/apps/compiz/plugins/snow/allscreens/options/snow_over_windows

[mcz]

Hi watkin5,
I have only these options:

Max Frames
Num Snowflakes
Screen Boxing
Screen Depth
Snow Size
Snow Speed
Snow Texture

[mcz]

Hi,
I had the old schema installed.
Now it works, but sometimes the cube and the snow are not fluid.

[zachtib]

Here's what i get when i make install
[: 1: ==: unexpected operator
compiling : snow.c -> build/libsnow.lo.lo-e
linking : build/libsnow.lo -> build/libsnow.la.la-e
install : /home/zach/.compiz/plugins/libsnow.so.so-e


and no option for the snow shows up in gconf-editor, even after i've loaded the plugin (or tried to) and i see no snow.

[mikedee]

You need to type this, sorry Ill include it in the makefile soon

gconftool-2 --install-schema-file=snow.schema

[zachtib]

You need to type this, sorry Ill include it in the makefile soon

gconftool-2 --install-schema-file=snow.schema

That fixed everything, thanks a lot.

now I can have snow+compiz :D

[amgeex]

I have snow, plus flowers, ubuntu logos, hearts, and several other things falling down my desktop!!! I loaded all the snow textures though. :D :P

[stjepan]

I set textures, but it always says it can't found the images!
[Snow]: Texture not found : /home/stjepan/.compiz/images/snowflake_2.png

Huh... why is this? :(

[mikedee]

Do you have the png plugin loaded?

Load it after gconf

[stjepan]

Thanks, works now.

[stjepan]

0.2.0 released! http://cornergraf.net/projects/xglsnow/

When will this be updated?

[mikedee]

I am working on a final christmas release very soon

Christmas shopping has put a bit of a dent in the timeframe :)

[mikedee]

I have just checked a diff of 0.2.0 against my version and my version is the same except it has rotating snowflakes. They must have been removed at some point because I was sure the last version I ported was 0.2.0.

Please let me know if you see something different :)

[stjepan]

For me the snow plugin is quite buggy. It works nicely for some time, but then I see only white squares until I restart compiz.
I hope this is fixed in 0.2.0

[mikedee]

As far as I know you HAVE 0.2.0 - in fact your version is a more advanced 0.2.0 than the one on their site.

[lagorgy]

how do i know i have png plugin installed? and if i dont where can i download it?

[iznogood]

its easy, just open gconf-editor and check apps/compiz/general/allscreens/options/active_plugins

There you can see all active plugins.If png is not there just add it by double clicking on the list(put it just after gconf)
Png plugin comes with compiz core so if you have the correct version then you should have it(you can check for libpng.so in /usr/lib/compiz)

thx for ur help.
I loaded png plugin right after gconf, and still snow plugin doesnt seem to be loading the textures... any idea?

[iznogood]

ok, just a couple of things...
First make sure you have the textures somewhere.Mine are in ~/.compiz/images

Second you must tell snow plugin where to get them, so open gconf-editor and goto apps/compiz/plugins/snow/allscreens/options and in snow_textures list put the textures you want snow to use(can be more than one) but with full path like /home/<username>/.compiz/images/snowflake_0.png

If it does not work after that, then...

hehe, i had already done that and didnt work, did it again and now is working

thx for ur help ;)

[cortex]

I have snow with super+F3

But on snow in app/compiz/plugins

So I can not change the square snow to other snow.png. How do I get snow in app/compiz/plugins ?

[mikedee]

in the snow folder type this

gconftool-2 --install-schema-file=snow.schema

Then restart gconf-editor and you should have the options

[cortex]

Mikedee

Thanks !!! Worked perfect.

[mikedee]

I have just updated this to a new version, there are a few bug fixes.

[sagara]

I have snow, plus flowers, ubuntu logos, hearts, and several other things falling down my desktop!!! I loaded all the snow textures though. :D :P

Where can i get the flowers, ubuntu logos and hearts textures?

[giancarlo]

Hi, mikedee, can you please instruct me how to install the snow plugin? I really love that plugin :D but it is not working with my machine.i'm using opensuse 10.2. compiz fusion is working fine i think(except i have to type emerald --replace everytime..)i save the snow tar at
/home/gian/compiz-0.4.0/plugins/snow


i dont know where to compile it, etc.

Im sorry for my newbie question, and thanks in advance :)

[SmSpillaz]

The one that mikedee offers is not up-to-date with core changes. You'll have to use the one in plugins unsupported.

Make sure you have installed compiz-fusion-devel and bcop, and just issue ./autogen.sh make and make install

[saxin]

Will this work with CF that comes pre-installed with Ubuntu 7.10 too?

[giancarlo]

i have an error while installing snow plugin
libtool: command not found
make: *** [build/libsnow.lo] Error 127

can someone help me please, i realy want this plugin
thanks in advance :)

[matt_evans]

i downloaded the tar.gz file to my desktop, and when i run the tar -xvzf snow.tar.gz command the terminal responds:

tar: snow.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error exit delayed from previous errors

I pretty much just started using linux so any directory manipulation would have to be explained to me. Thanks.

Install libtool :-)

[shame]

I really wish the mouse/screen edge bindings for snow would come back.
I used it quite often before, when I could clisk at the edge of the screen but when I have to press a key combo I just can't be bothered.

[rezonence]

Hi! I'm having some problem with the snow plugin... I'm using Suse 10.3 and i've installed via YaST compiz-fusion-kde , the main and extra plugins and it all works just fine. But then I tried to install the Unsupported plugins and although they appear in the Settings Manger, I can't enable any of them [mswitch, snow, tile] - that is - i can check them but they dont remain checked. And another thing, at the snow plugin there are no options to initiate it.

I've tried to download the .tar.gz snow plugin and compile it but it gives some errors....
If you have any ideas please share them with me.
Thanks!

[SmSpillaz]

What output do you get when starting compiz and trying to enable the plugin?

[rezonence]

"Attempted to unregister path (path[0] = org path[1] = freedesktop) which isn't registered
Attempted to unregister path (path[0] = org path[1] = freedesktop) which isn't registered

[the last line is repeated several times]
It would seem like there's a problem with the ABI version... but I dont really know what ABI is and how to get a newer version... will do some searching though...


Later edit:
Did a compiz-all-related uninstall and reinstall of compiz-fusion-kde, installed the unsupported plugins and it works now! :)

[dsvilko]

Would it be possible to add a snowflake rotation in the other two axis?

[gord]

I can't remember where i got this version of the snow plugin, but i put in a few hacks anyway, full axis rotation instead of just on the z and fixed a bug regarding snow rotating around a corner rather than rotating around its center. compiles for me with the ubuntu gutsy compiz fusion, don't know about anything else.
