pipmak-users — Content creation for the Pipmak Game Engine

my demo...

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

I decide to revamp the demo, let face it it was boring! so now its a mini
game on a secret island, the task is to retrieve a golden relic, at the
moment its only preview rendered images and 7 nodes the plan is another 5
nodes, maybe more, it'll still be a open source demo for people to learn
from, i might need some help with the main puzzle, but i can leave that
until last http://www.nabble.com/file/p18576311/ouside.jpg ouside.jpg

Re: Inventory

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

With Aidan help i now have the inventory and items removed from nodes..
(thanks :) )

I've managed to get a key working on a door using the demo as reference but
i need to fine tune it a bit, currently the door unlocks an i go to the next
node with the key.. i'd like the door to unlock and the key stay there, and
the user click on the handle to leave, the key turn is animated key2.jpg to
key5.jpg
a message if the door is locked or unlocked

Re: A game I created with Pipmak

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

I really should go about game development the same, instead of going feet
first with graphics that inevitably have something missing and impossible to
fix without having to render multiple scenes (just realised i missed
something with mine :blush: )

Kind of got my key/door working with animation but i need to fine tune it a
little lol

Nice work Aidan

A game I created with Pipmak

[Aidan G. <wgs...@ih...>]

Hello,

  Nige was asking me about using the inventory from the Pipmak demo, and I 
remembered that I did something similar to what he was asking how to do.  So I 
told him that I'm working on a game with Pipmak, and that he might want to 
look at my code for that.  And then I thought "why don't I mention this on the 
Pipmak mailing list while I'm at it?"

  So here it is...
https://coldrain.svn.sourceforge.net/svnroot/coldrain/trunk/
you can get it from there using Subversion.  But it's not yet playable, or 
even ready for testing.  I'd say that it's in the pre-alpha stage.  I'm 
currently working on the graphics for the next stage.

hi Aidan

Email will be fine nig...@gm...
I'm really greatful for the help, if you don't ask questions you never learn
;) and I'll add this part to the other  demo, I think we'll have all the
basic bases covered then

Thanks again

I think I fixed all the problems you mention here, and your questions aren't 
that stupid.  If you're not a programmer, then it can be hard to solve 
problems like this.

How should I give you my changes?  Would it be OK to E-mail you a modified 
copy of your Pipmak project directly?  I just don't want to send large 
attachments without warning.

Inventory

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

sorry to trouble you again.. but i'm having inventory problems now

I figured out how to pick items up, add to inv and lose the patch image on a
slide, but i'm not sure how:
to remove the patch image from the cubic node you return to
use the inventory item ie the key on the door..

I tried working from the demo, but nothing was clean cut, picking up an item
was easy but the key in the demo was more involved

here's what i have so far:
http://www.nigecstudios.co.uk/games/loo_v1.rar

on the first node the card on the floor is a patch on face 1.. i messed up
and the card image its on two faces on the second node

going from node 2 you can enter a toilet and pick up the key
so i need to lose the key and card on node 2 once taken and the card on node
2

sorry for the dumb questions.. in my defence ii'm not a coder!

Re: horizontal fov

[Andrea V. <and...@gm...>]

Hi,

Ok, it's correct, because my formula go well only with elevation=0

I believed to found a formula that permit me to put four patches at four
angles of the field of view, and I expected (wrong) to view these 
four images always at the angles of the screen, 
but this is true only with elevation=0.

Ok,ok, it's only an accademic discussion...just to learn....

I now have sound attached to the door handles, i was going to look at adding
opening animation.. altho i didn't compansate for that with the model, so i
might leave that until next time  
I'll also comment the node.LUA's so it explains what does what, and i need
to add one of Andrea's alterations to my version 

This little exercise does address a number of points dispite its size so
hopefully it'll help a few people:) 

I'll have a think what was bothering me and see if i can come up with
something else ;)

Thanks, that looks very useful. I agree that it's not quite 
straightforward to achieve such things in Pipmak, since it only provides 
the basic building blocks for it. If we can identify areas where it 
would be useful to include higher-level (but still generic enough) 
functionality directly in Pipmak, built upon the existing low-level 
capabilities, I'm open to that.

If you consider this project finished, sure, we can add it to the 
showcase page. Perhaps with a link to the wiki page about it. Just give 
me a download link, and if you want, a preferred screenshot and text 
that matches the style of the existing entries (otherwise I'll come up 
with those myself).

That's what I would recommend for such a demo too.

In addition, for the case of a full release that includes Pipmak, I 
would recommend renaming Pipmak.exe to the name of your game, maybe 
giving it a new icon, and moving the readme files into a subfolder. 
Otherwise users might be a bit confused about what files belong to what 
and what to double-click. (I don't insist that you include History.txt 
and To Do.txt, but Acknowledgements.txt, COPYING.txt, and Read Me.txt 
should be there because of the license information in them. Perhaps I 
should think about embedding them im Pipmak somehow, so that you can get 
rid of all external files.)

I don't have any specific ideas at the moment, but I like the idea. 
We're indeed lacking in the area of tutorials and simple example 
projects. Thanks for the offer!

Well, I guess I could work out the math... but I think it would be 
easier to just implement the specifiable rotation order. Would that be 
acceptable to you (i.e. you would have to use your own build and/or wait 
for the next release)?

horizontal fov

[Andrea V. <and...@gm...>]

Hi Christian,

Another exercise for you...

I have tried to calculated the horizontal fov:

      width,height = pipmak.screensize()
      vfov_deg = pipmak.getverticalfov()
      vfov_rad = math.rad(vfov_deg)
      distance = (height/2)/math.tan(vfov_rad/2))
      hfov_rad = 2*math.atan((width/2)/distance))
      hfov_deg = math.deg(hfov_rad)

but it's not true, because I get an angle lower than what I can measure.
What I have forgotten?

Thanks

Andrea

Re: on screen dialog

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

Hi Andrea 

I agree the showcase section would be better, with an explaination on what
its for :)

and yes it makes more sense to have it as a .pipmak file rather than a
single OS

the alterations are a lot better, I made my copy so the door near the
picture never opened but displayed a message, thanks to you i'm now
confident using the text system.. i wouldn't of figured it out lol

If you can think of any other useful demo's i'll gladly do the demo
resources, rather than trying to do a full game i'm building mini levels so
problems are broken down into small segments

take care
Nige

Re: on screen dialog

[Andrea V. <and...@gm...>]

Dear NigeC,

1) I think that the best place to publish your little demo would be in 
   the Pipmak Showcase (if Christian will be agree), because it could 
   be very usefull for newbies (the official Pipmak Demo is more 
   complicated because it want to show all Pipmak features...)

2) I think that the best way is to publish just the file hallway.pipmak 
   without engine (which is downloadable from the official site), so
   everyone will try the demo in its platform.

3) I have modified hallway.pipmak again, so if you go back from the beach 
   to the hallway (placing the cursor down), you will be transported to
   the room with the door you have overstepped (this could demostrate an
   use of a sort of "conditional" jump....) and the writing is deleted.

   I have update http://andrea.viarengo.googlepages.com/hallway.zip

What do you think? And Christian too?

Bye

Andrea

If you want to add the demo as an example for the wiki topic your welcome

the othere door has dialog too
http://www.nigecstudios.co.uk/games/halway_demo.rar is a working demo under

I don't want an elliptic sun (part II).... (advanced 3d patch placement )

[Andrea V. <and...@gm...>]

Hello Chriss,

I'm returning to the application for orienting a patch to the viewer
given azimuth and elevation.

Your modification of my setpos(p,dis,az,el) works very fine with a sun image
which has a circular symmetry, 
so, rotation around its perpendicular axis pointing inward,
does not matter very much,

but how could I calculate parameter "angle" (that we haven't included before
in the "move" statement), so the bottom of the patch remains parallel 
to the "xz" plane for every value of azimuth and elevation? (i.e.: in other
words, if I write something into the patch, I would like that the text
remained parallel to the ground)

You are very good at trigonometry, I am sure that this will take just a moment!!

Thank you!!

Andrea

Re: on screen dialog

[Andrea V. <and...@gm...>]

Hi NigeC,

Ok, I have posted hallway.zip here:

   http://andrea.viarengo.googlepages.com/hallway.zip

with these modifications:

1) Added node 100 to use as overlayed node to show messages
2) Added recalling overlayed node where it needed
3) Added an hotspot to the keypad to permit to return to the hallway 
   and open the door if you have entered the correct number.
4) Added simple room 6 behind the unlocked door.

Is this what you needed?

Hi Andrea 
Is there any chance of seeing it in context?
my little test project is here (6meg ouch):
http://www.nigecstudios.co.uk/games/hallway.rar
either door will do as they are both locked, one door never opens the one by
the keypad will (when i figure out that bit)
