I can't think of a way. It could be done by adjusting the pan limits to 
the single point you want, but you can't currently change those without 
reloading the node.

I'll take that as a feature request, then. (And hope I won't forget it - 
put it into the feature request tracker if you want to make sure.)

Re: Smoothly rotating to another angle on pano nodes

[James C. W. <jfc...@ya...>]

Yesterday I realized most of those problems, and fixed them. The new code runs very well, but oddly enough, doesn't return to exactly the defined target location, missing by about 1.5 degrees x, and 0.2 degrees y.
Here's the new code, commented. Sorry about not commenting the older code-it was quite late.
 
--included in node.lua
hotspot {
  onmousedown = function()
  autoPan_tarAZ, autoPan_tarEL = 270, 4
  autoPan_time = 1
  autoPan()
end
}
 
--autoPan.lua: an add-on file included in main.lua.
 
autoPan_funcCount = 0 --the number of times the function has been run.
autoPan_time = 1         --the duration, in seconds, the rotation should take to complete, set 
                                  --by onenternode in node.lua
autoPan_rate = 0.025   --the framrate of the rotation, e.g. how many times it runs per 
                                  --second.
autoPan_iterCount = 0  --the number of times the function should run, in order to get to the                             --target angle.
autoPan_tarAZ, autoPan_tarEL = 0, 0     --The target angle.
autoPan_viewAZ, autoPan_viewEL = pipmak.getviewdirection() --the current angle.
autoPan_speedAZ, autoPan_speedEL = 0  --the degree value which gets added to the   
                                                         --current view angle each time the function runs.
function autoPan()  --defining the function
pipmak.schedule(
    autoPan_rate,     --borrowing the framerate from the global autopan_rate.
  function()
      autoPan_viewAZ, autoPan_viewEL = pipmak.getviewdirection()  --each time the function                                              --is called, set the global to match the current viewing angle.
      if autoPan_funcCount == 0 then  --if the function has been run 0 times,
      autoPan_iterCount = (autoPan_time) / autoPan_rate  --then divide the duration of the 
                                                                                  --event by the framrate, getting the number of times the function should be run, and dumping it into autoPan_iterCount,
      autoPan_speedAZ = (autoPan_tarAZ - autoPan_viewAZ) / autoPan_iterCount  
                                                                      -- Subtract the AZ viewing angle from the 
--target, and divide by autopan_iterCount, to get the the degree value which gets added to
 --the current view angle each time the function runs.

      autoPan_speedEL = (autoPan_tarEL - autoPan_viewEL) / autoPan_iterCount
                                                              -- Subtract the EL viewing angle from the 
--target, and divide by autopan_iterCount, to get the the degree value which gets added to
 --the current view angle each time the function runs.

      end
        
      if autoPan_funcCount == autoPan_iterCount then   --if the # of times the function
                                               --has been run equals the target number of times, then...
      autoPan_funcCount = 0      --reset to 0,
      return                             --stop the function.
      else                                        --if NOT, then...
      autoPan_funcCount = autoPan_funcCount + 1    --increase the # of times the function 
                                                                           --has been run by 1.
      pipmak.setviewdirection(autoPan_viewAZ + autoPan_speedAZ, autoPan_viewEL + autoPan_speedEL )                                                --add the neccessary change to each
                                                --degree axis, as determined by the previous calcualtions.
      end
      return autoPan_rate              --borrowing the framerate from the global autopan_rate.

   end
  )
end

 
CODE END.

I probably can, if you can explain what exactly you want to achieve, or 
what you expect this code to do. I can see that it approximately does 
what you describe, but I can't tell in how far that is not what you expect.

A few comments on details that seem strange to me:

You don't handle the case viewAZ == tarAZ here and leave speedAZ = nil

What's the point of this assignment? It has no effect since in the "if" 
statement you just checked that its outcome is already true before.

Re: saveequirect not working

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

Hello Phil

Welcome and I'm sorry you had such a frustrating experience! We'll try 
to help as well as we can.

> I can't seem to save the
> equirect.bmp.  I've gone through quite a few posts on hotspots and such, I
> can make them.  I was wondering if pipmak.saveequirect() was taken out,

No, it's still there. Don't worry, it won't be removed before there is a 
better replacement (direct painting within Pipmak).

> I can't find it anywhere in the defaults.lua file.

Yes, it's in pipmakLuaLib.c, not in defaults.lua.

> read that it was likely to be removed but I don't see why. 

Because it is a quick and dirty hack. For example, it tries to save the 
image under a fixed name in a fixed place where it may not even have 
write permission.

How did you come to the conclusion that it is not there? Do you get an 
error when you try to call it? If not, then it is there, and we just 
have to figure out why you don't see its effect. If you don't get a 
message saying "Could not save BMP file" on the Pipmak terminal, then 
saving should have worked. It saves in the current directory, which is 
supposed to be next to the executable (because Pipmak sets it that way 
on launch). On Mac OS X, that is inside the application bundle under 
Pipmak.app/Contents/MacOS. (I see that this is not explained properly in 
the documentation. I wonder if that's a mistake or if it was different 
and the documentation was right in an earlier version...) What version 
of Pipmak on what platform are you using? Perhaps something is wrong 
there and it actually saved somewhere else. Have you searched your 
computer for a file named "equirect.bmp"?

Agreed. All I can say is that you are working with a work in progress 
here. Things will get better over time. The more people help, the faster.

That said, I didn't find it that frustrating - I was able to get my 
hotspots right with a few iterations of painting and checking them in 
Pipmak. You are aware that you can reload the node while it's running in 
Pipmak and immediately see the edited hotspots, right?

> Handles seem even more frustrating, I haven't even tackled them yet.

Why would they be more frustrating? You can even move them within Pipmak 
using the Lua command line, so I would consider them slightly less 
frustrating at this point. Obviously the non-frustrating solution would 
be the ability to move and resize them by mouse, but that is not 
implemented yet.

I can't think of a way. It could be done by adjusting the pan limits to 
the single point you want, but you can't currently change those without

I'll take that as a feature request, then. (And hope I won't forget it -

saveequirect not working

[armylegend <chi...@ho...>]

Hey there, I'm somewhat new to Pipmak.  I can't seem to save the
equirect.bmp.  I've gone through quite a few posts on hotspots and such, I
can make them.  I was wondering if pipmak.saveequirect() was taken out, I
can't find it anywhere in the defaults.lua file.  Is it even supposed to be
there, read that it was likely to be removed but I don't see why. 
       I've spent like 5 hours at my computer trying to find a good way to
map out hotspots for panoramic views, it's just so sloppy not knowing
exactly where to put them.  I'm using Gimp pulling out all the stops using
all my tricks trying to accurately place them to no avail.  There is nothing
streamlined about this method at all which makes node creation INCREDIBLY
tedious.  Handles seem even more frustrating, I haven't even tackled them
yet.  
       That being said, I'm EXTREMELY excited about pipmak and I'm very glad
there is an adventure game engine available like this.  I was sad to see
SCream fold :-((.  Unfortunately, if this ends up being too time consuming
with little return, I'll likely just start spending my energy in another
project.  I'm a pretty hardcore adventure gamer so I don't want to, but hey,
whaddya do?

thanks,
Phil

Disabling Panoramic rotation

[James C. W. <jfc...@ya...>]

Hi all,
 
Is there a way to stop the player from turning in a panorama? I need to disable movement so that the camera can smoothly rotate to a different direction without the player interfering, then restore control to the player once it's done.
 
Thanks, 
  James


      

Smoothly rotating to another angle on pano nodes

[James C. W. <jfc...@ya...>]

Hi all,
 
I've been working on a library for cubic panorama rotation, and have run into a problem. 
When I run this code, Pipmak will smoothly rotate to either 90, 90, or 90, -90(disregarding panorama limits), and slowly spins.
I can tell there's something wrong with this code, but I don't know what it is exactly, or how to fix it. Can anyone suggest a possible solution? Thanks very much, if anyone can.
 
CODE**********************************************
 
cubic { "front.jpg", "right.jpg", "back.jpg", "left.jpg", "top.jpg", "bottom.jpg" }
local tarAZ, tarEL = 45, 45
local viewAZ, viewEL = pipmak.getviewdirection()
local speedAZ, speedEL
   
      if viewAZ > tarAZ then
        speedAZ = viewAZ / tarAZ 
      elseif viewAZ < tarAZ then
        speedAZ = tarAZ / viewAZ 
      end

Yes, I have, and it has considerable use. I'm using color.lua to write curvemotion.lua, details of which, and a few other new ones, can be found on the library page, on the Wiki.

As mentioned here 
<http://thread.gmane.org/gmane.games.devel.pipmak.user/560/focus=625>, I 
apparently need to give everyone write permission individually. I assume 
your SourceForge user name is "jfcwilson"? I have just added that user 
to the editor group. Let me know if you still have trouble editing.

I didn't realize this at the time I evaluated the wiki, and I'm not 
happy about it because it somewhat defeats the purpose of a wiki. If you 
  would like SourceForge to change it, please vote here:

Accessing the wiki?

[James W. <jfc...@ya...>]

Hi all,
 
How can I access(edit) the wiki? Even when I'm logged in to sourceforge, it tells me I need to be an admin or something...
 
Thanks,

For what it's worth, enabling this has been on my mind as a vague idea - 
but it hasn't even made it onto the official to-do list yet. See

Re: Screen capture?

[James W. <jfc...@ya...>]

I see. Thanks. The reason I wanted to do this was to create a graphical save game system.
So I don't think that using something like the print screen key would work, as it has to be automated.
 
Thanks, 
 James

I'm not sure what you're asking here.  All Lua functions provided by Pipmak
are interfaces (for lack of a better word) to a function built into Pipmak.

If you mean a Lua function that is part of the standard Lua library, then I'm
sorry to be the one to tell you that Lua is more primitive than you seem to
realise. ;)

Oh, and this will will probably never be implemented in Pipmak, because it is
so simple to just take a screen shot of the window on just about any system.

Screen capture?

[James W. <jfc...@ya...>]

Hi all,
 
Is it possible to capture the screen and save it to a file? I know it isn't built into pipmak, but is there a Lua function for it?
 
Thanks,

Oh, sorry.  I only use the source from Subversion repository, and I didn't
check to see if that's included with the binary releases. :P

Re: Need help with hotspot maps

[James W. <jfc...@ya...>]

I think Aiden forgot to add that you can only find the palette in the source code download, not the bineries. Also, note that you must place the hotspot in node.lua according to the location on the indexed hotspot file. Like so:
 
If you have one hotspot that is the first(or ordered first, it doesn't actually matter what color it is, as long as it comes before the others in the palette) color, you include the following standard hotspot line in node.lua:
 
hotspot { target = 2, effect = { pipmak.rotate, pipmak.left, 10, state.slideduration }, cursor = pipmak.hand_right }
Make sure that it is the FIRST hotspot definition in the node.lua file.
Then go from there.

There are no pre-established colors that are used, but the colors used by the
image file itself.  An image with indexed colors is one that uses its own set
color palette of up to 256 colors.

Pipmak comes with a color palette that is well suited to drawing hotspot maps,
because of the contrast between the colors.  The file is "hotspot-palette.gif"
in the folder "extras" (that comes with Pipmak).  How to import this into your
bitmap-image editor depends on what you are using.

So, in short...
* Your hotspot map has to be an indexed image (not RGB).
* The first color on the palette maps to the first hotspot, the second color
to the second hotspot, etc.
* /Anywhere/ color 0 appears on the image will be hotspot 0, so hotspots do
not have to be all one (visual) piece.

Hope this helps,
Aidan
