I was looking at section 3: "Changing the interface".

Oh, I see.  Then what I read on MediaWiki's site does not apply.  Sorry.

Perhaps changing the look of the Pipmak just to give it a Pipmak look is not a 
wise decision, as portability may be reduced in the process.  Now would 
probably be good time to mention that the left navigation/tool bar on the 
Pipmak wiki does not render properly for me: it is placed after the rest of 
the content on the page, but still on the left side.

That page is very long. Can you point me at the specific section that 
implied that?

Maybe I'm misunderstanding you, but yes, the non-customizability is 
SourceForge-specific. They just don't give you access to the files. I 
know how to customize a MediaWiki that I have full control over, that's 
exactly what I've done for the existing Pipmak wiki.

Re: Spammer on the wiki!!

[Christian W. <cwa...@gm...>]

Thanks for the notice and clean-up, Andrea. I have now blocked these 
users. I hesitate to block everyone on the users list that looks like a 
spammer before they actually post any spam, because I might mistakenly 
include some legitimate users. Unfortunately, requiring confirmation for 
account registrations is easier said than done because we can't send 
e-mail from the SourceForge web server. For the moment I have disabled 
account registration altogether, until we find a better solution. People 
who want an account can contact me and I will add them.

I wonder whether it would be a good idea to switch to the 
SourceForge-provided MediaWiki now 
(http://apps.sourceforge.net/mediawiki/pipmak/) instead of trying to 
maintain our own outdated installation. When it was introduced, I 
originally decided against it for various reasons, but some of them have 
been eliminated now, and a reconsideration may be in order. Some 
upcoming changes to the Hosted Apps have just been announced (by e-mail 
to project admins, it doesn't seem to be on the web anywhere) and I'll 
have a closer look when they are implemented in 1-2 weeks. The advantage 
would be that the burden of administration is taken off us (me). The 
biggest disadvantage I see right now is that we would lose the 
Pipmak-specific look.

Re: Debian Linux, Pipmak won't run

[NigeC <nig...@gm...>]

I'm on Debian 5, the libopenal build is libopenal1 1:1.4.272-2

It didn't run on Ubuntu 9 either, but that was the version you could run
inside windows so there wasn't a great deal installed

Re: Debian Linux, Pipmak won't run

[Christian W. <cwa...@gm...>]

Thanks for taking care of this, Aidan. Looks like this would be a good 
test for your new build procedure, why don't you just make a build and 
send it to Nige?

For what it's worth, the official Pipmak 0.2.7 release was built on 
Debian 4, with OpenAL from package libopenal0a version 1:0.0.8-4. I have 
no idea what the current version is as I haven't updated that virtual 
machine since then.

I'm surprised that it works with libopenal.so.1 because as far as I 
remember that number is used specifically to mark incompatible library 
versions.

cwalther@debian:~$ ldd pipmak/build-linux/pipmak
	...
         libopenal.so.0 => /usr/lib/libopenal.so.0 (0xb7681000)
	...

Re: Debian Linux, Pipmak won't run

Thanks Aidan that worked :) If you want me to test thinks feel free to drop
me an email or ask here
The plan is to build a game demo under Linux and try to give the project a
push ;)

Oh, great..(NOT!)  OK, here's the deal: recently, I made some major changes to 
the Linux build system, and Christian decided to let me, more or less, take 
over maintence of the Linux build system.  I made those changes, because I 
thought that the Linux build system wasn't very good in some ways 
(particularly with linking to libraries).  I hope the next release of Pipmak 
will work better on more Linux distros and for you.

In the mean time, might I sugguest a work-around: find the libopenal.so.* on 
your system (hint: try the package manager), and make a symbolic named 
"libopenal.so.0" to the libopenal.so file.  (There may be several files whose 
name starts with "libopenal.so", but only one will be a regular file; link to 
the regular file, not one of the links.  All the existing links will link to 
the same file.)  If you don't know how to do this, E-mail me off-list, or if 
you know how to use IRC, go to #tuxhacker on irc.freenode.net.

Are you using the latest development revision from Subversion?  If you are, 
then check out again, because I just made a change to the Linux Makefile that 
may help.  Also, if you're building from the source in Subversion, you should 
set usesyslibs=t when you run make (i.e. type "make usesyslibs=t" instead of 
just "make").

Hope this helps,
Aidan

What do you mean by "get no folder/file"?  Does it complain about missing 
libraries?  If you get an error message about not being able not find 
libraries, then it's probably the operating system failing to even execute Pipmak.

New simple example project: Pipmak Castle

[Christian W. <cwa...@gm...>]

Have you ever considered using Pipmak for your own projects, but were 
overwhelmed by all the intricate details in the scripts of the Demo 
Project? Thanks to James Wilson, we now have an example project that 
shows how easy it is to make a simple explorable world. Download Pipmak 
Castle at 
<http://prdownloads.sourceforge.net/pipmak/PipmakCastle.zip?download> or 
look on the Showcase page <http://pipmak.sourceforge.net/showcase.php> 
for a small screenshot.

PS: It occurs to me - perhaps I wasn't clear enough about this: The  
code examples I gave in yesterday's message (those between --------)  
were complete node.lua files, not code snippets that you paste at some  
point into the code of another node.

"slide" is not a function that you can call at any time to create a  
slide node out of thin air. It is only used at the top level of a  
node.lua file to describe that particular node, and is only defined at  
the time the node.lua file is read. It is technically a function but  
you shouldn't think of it as one, rather as a statement in a  
declarative node description language. (I know that statements like  
the 'local img = something; slide (img)' I proposed blur that notion,  
that's why I consider them inelegant and confusing. The slide  
statement is really intended to be used only as 'slide "imagename"' or  
'slide {"imagename", more stuff}'.)

I'm a bit confused by your desire to display a third node when the  
player moves from one node to another (rather than at some other time  
determined by your game code). Do you want the move to be canceled and  
the popup displayed above the old node, or should it be displayed on  
top of the new node? (Are there several possibilities of what the new  
node can be? If there's only one, it would seem more natural to me to  
do this in the code that triggers the leaving than in the onleavenode  
handler. Or in the new node on entering.)

Here's how displaying it on top of the new node should work:

onleavenode(
   function()
     pipmak.overlaynode(123) -- node 123 is your popup
   end
)

   -Christian

Re: Manual Questions

[chikitin <cs...@gm...>]

Thanks much for the answers. Unforntunatly it seems none of the methods that
you describe for for me. 
I want pipmak as soon as leaves a specific node, show the small fram in the
middle of the page and start over the game. well, I supposed something like
this work:

img = pipmak.newimage("congratulations.jpg") // picture file is in the node
folder

onleavenode(
function

slide(img)

end
)

but this gives me an error:attemp to call global slide ( a nil value). 

thanks in advance,

You can do either (or even both at the same time). It depends on what  
exactly you want to do, there are a lot of combinations.

If you want to display the "congratulations" box on a screen of its  
own, you can make it a separate slide. If you want to display it on  
top of a panorama, make it a slide with transparency (scaled to fit  
the screen) or a panel (kept at screen resolution) and display it as  
an overlay. If you want to display it on top of one particular slide,  
you can make it a patch on that slide node.

If you are satisfied with Pipmak's text rendering and don't need any  
fancy effects on the text, or want to be able to change the text  
easily, you can use image:drawtext. Otherwise, you draw the text  
yourself in a graphics program and incorporate the result as an image.

Here's a working example of a slide with a background picture and a  
patch containing drawn text (using a built-in image and font for  
demonstration, you will want to use your own image and perhaps your  
own font):

--------
slide "../resources/missing.png"

patch {
   x = 0, y = 50,
   image = pipmak.newimage(128, 20):color(1, .5, 0):drawtext(64, 0,  
"congratulations", "../resources/Vera.ttf", 16, pipmak.center)
}
--------

You could also draw the text directly on the background image:

--------
local img = pipmak.newimage("../resources/missing.png")

img:color(1, .5, 0):drawtext(64, 50, "congratulations", "../resources/ 
Vera.ttf", 16, pipmak.center)

slide (img)
--------

Or even create the whole background image programmatically:

--------
slide (pipmak.newimage(640, 480):color(1, .8, .5):fill(150, 200, 340,  
80):color(.4, .2, 0):drawtext(320, 210, "congratulations", "../ 
resources/VeraBd.ttf", 24, pipmak.center))
--------

Does that help? I admit that this is all a bit complicated and low- 
level, that's why Andrea has created a more user-friendly text display  
system on top of it that will be integrated into the next version of  
Pipmak: http://thread.gmane.org/gmane.games.devel.pipmak.user/454

No. You need to keep track of that yourself if you need it, by adding  
an onenternode handler to every node that takes the node number and  
appends it to some list in the state table, or something. You could  
put that into its own file and include it in all the nodes using  
pipmak.dofile() to avoid duplication.

What you want is "pipmak.print", not "print.pipmak". The function  
that's stored under the name "print" in the table "pipmak". What  
you're trying here is to get the entry named "pipmak" in the global  
variable "print", which doesn't work because "print" is not a table  
but a function (one that prints to standard output, which is of  
limited use in Pipmak).

Yes, there is math.mod(a, b):

http://www.lua.org/manual/5.0/manual.html#5.5

math.fmod() is new in Lua 5.1, which Pipmak doesn't use yet. bit.mod()  
is not part of the standard libraries that come with Lua and are  
included in Pipmak.

As that page says, "a few functions differ slightly in Blizzard's  
implementation", so in general you're better served by the Lua 5.0  
manual (link above) for the standard functions and the Pipmak manual  
for what Pipmak adds to them, than by documentation about World of  
Warcraft or other applications that use (possibly modified versions  
of) Lua.
