Have you ever heard of it it well if not search in google

I am planning on remaking it but how would I go about making the physics??

Anyh e;lp onm anything would be nive


GfK(Posted 2004) [#2]
Its already been 'remade' - twice. Pontifex, and Pontifex 2.

There was also a Blitz remake. Its on the Blitzcoder showcase somewhere.


nnndoh(Posted 2004) [#3]
there is one remake of the game...called bridge it from auran software ( trainz)

very cool game though


Agamer(Posted 2004) [#4]
yes but I want make my own so I can mak eit better

First it would be good to know your vector maths.
Then you should do some research on programming "springs"

www.gamedev.net has many useful articles on the subject.
Articles->Maths & Physics->Physics Tutorials.

Third.. Do you read over your posts before posting? And if you do, don't you spot the errors in your lines? Its like you don't even care if others have trouble reading it.

sorry I will try harder my writing seems to have sliped back to it's old ways

Thanks for the help though

I think Auran's version (Bridge It) works only with nVidia cards as it was created in cooperation with nVidia. Otherwise it's an excellent example of the graphical power of modern PC.

is a fine game an i understand that u will make a remake


Agamer(Posted 2004) [#9]
yehit owuld be kwl if I could get teh source of that one remade in blitz but I htink the guy changed his e-mail adress any one know him cho coluld know


AbbaRue(Posted 2004) [#10]
Sounds like an interesting project, I look forward to seeing it at work.

The physics are the entire game. How do you plan to remake it if you can't code the core component?


Agamer(Posted 2004) [#12]
well tahts my point how do you go about it


Bot Builder(Posted 2004) [#13]
tokamak :)


Warren(Posted 2004) [#14]
My point would be, start with something simpler. :)


Bot Builder(Posted 2004) [#15]
yeah, that to :) if you haven't already, make pong or breakout or invaders or somthing :)

Eelco Hoogendoorn is the author of a 2D Bridge Builder program posted on BlitzCoder around the end of 2002.

The physics were quite good but the GUI quite primitive.

So ... Eelco and I have been collaborating on a new version that is nearing completion. The physics engine has been dramatically improved by Eelco and the GUI is looking good and working well (IMHO).

I don't know how close our product will be to the programs you referred to as I have not seen them in action.

As far as I know, neither of us has coded a BreakOut or Invaders game.

No Invaders or Breakout!?!? Now stop this bridge thingy and do your duty! ;)

Looks very nice btw!


Agamer(Posted 2004) [#18]
I have programed one f them it's just my physics whihch are bad and what is this tomak


AbbaRue(Posted 2004) [#19]
Tokamac is a physics library that has just been interfaced with Blitz3D. So it has become the latest fad around here. Everyone is exited about it's capabilities.

Now I hope someone discovers an awsome 3D engine that has 3D terrain tiling functions, and interfaces that with Blitz3D.


Agamer(Posted 2004) [#20]
Oh well I have made some progress into the subject

well I found out that to find out what the load of a metiral will take is what it will brake at so by

for compresion
_________
| weight |
|_________|
s
t =when snaps weight = load it can take
i
k

for tension

pulling weight
.
.
.= When snaps maximum tension = the 2 weights
.
.
pulling weight

I then know to have a large saftey margine about 75% of real wate

This is were I come to a problem though .

I need something to allow me to work which obne is actiing and thenwhat if they are both in it.

See why I am confused

Aren't you using one then? I've been using my own multilayered tiled terrain ever since vertex aplha got introduced. :P


AbbaRue(Posted 2004) [#22]
Do you have any sample code I could look at.
That function has no example in the command reference.
And I don't know how to use it.


Agamer(Posted 2004) [#23]
can any one help me Does any opneknow if that one pepole were looking about is still possible to get


PGF(Posted 2004) [#24]
If you are seeking the original code posted by Eelco then I suggest that you try on BlitzCoder. However I think that Eelco has moved his site so the link may well be broken.

Second chance is to contact Eelco directly.

I don't want to put you off but the physics simulation in even Eelco's original is quite complex. There are different materials with varying properties of mass, strength, elasticity etc. The effects of gravity, internal material stresses, wind and even water (wood floats, steel sinks). The properties need to be well tuned otherwise materials spontaneously self-destruct due to the limitations of the simulation mechanics.

For our new version, Eelco has significantly enhanced the physics in terms of both behaviour and performance. He is, I understand studying engineering so this isn't some unfounded little exercise.

There are of course many resources available to you if you want to develop your own code. Any good technical library will have books on mechanics, engineering and general physics. There is also a lot to be found on the Internet. Easier to get but as usual not as deep as a couple of specialist books.

A good starting point in either case is to look for 'Finite Element Analysis' or 'Finite Element Modelling'. The maths gets deep very quickly and I haven't yet seen anything that just says 'Write this and use these parameters for steel etc'.

Hope this helps.

Do you have Elco email adress so I can contact him or if he has still got a link to it.

I e-mailed him on his adress on blitz coder but that was about a week ago and no reply


PGF(Posted 2004) [#26]
I'll send you info directly.


Agamer(Posted 2004) [#27]
thx


Agamer(Posted 2004) [#28]
have you sent it yer PGF


PGF(Posted 2004) [#29]
Yes - sent it at about the same time as my last reply (nearly 2 days ago).

E-mail me directly if you still haven't received it. The address in my profile here is correct.
