Is the GTA3 trainmodel converted yet ?

I've been experimenting with getting an object to ride the tracks,
And i've been able to send it around without backing in the curves, with just a minimum amount of code ( 5 or 6 lines).

I'm using the Cortez-ship path fromvc ( spath0.dat ), to send the object around.

At the moment I'm using a waterjump as a train-car, it's a wierd sight but you can easily get on it, and take a ride around.


It's just making a single tour yet, but simple scm-coding will be able to fix that.
Also making the train (multiple cars) stop at the stations for a certain time should not take too much coding.

What I need to do further testing:
- model of a train car (with col) that can be entered from the side.
- detailed description of the behaviour of the train in GTA3, as I haven't played it myself...

I'll do the train for you in a bit. No reflections as I doubt the train would have reflective surfaces. doors will either be missing or you can walk right through. 1 q though how would it be possible to have multiple cars? 2 or 3 cars per train * 4 trains

I think it should be possible to move multiple cars/trains.
I'll do some simple tests and report my findings.

OK well I was going to post the files that needed to be placed in the GTA3.img but my webhost is messed up. I just extracted the need files from the ps2 disk as I can't find my pc disks right now.
I was going to do more work on the files but I rather see the train in action before I fix any model problems.

[PatrickW]

Mark,

I just conducted some tests, and it turns out that the engine will support upto 3
independantly moving objects using this method. A three car train should thus be possible, but we could also opt for three seperate 1 car trains.
(Adding a fourth car crashes the game )

I'll be happy with any model at the moment, so that I can start weaking the path-coordinates, and add the extra code for repeated loops and stopping at station.

I'll need some info on the trainbehaviour in GTA3 to accurate recreate it.

[Mark Pagliaro]

Cortez's Yacht as made with upto 3 dff files thats why 3 works. Anyways here are unaltered files.

I am currently Playing GTAIII on my ps2 as I stated I cant find my pc stuff but what sort of info do you need on the train? Ps2's train is modeled differently from that of the pc yet the basic shape remains the same.

I know that cortez Yacht uses 3 models, but they are all atached to 1 "special_object" ( I call them path_wanderers). This means that all three objects will always be located at the exact same position. To create three independent cars I create 3 wanderers with each an car object atached.
But possibly is there just a limit on three path-wandering objects...

I'll need some basic info on the train behaviour:

I'll figure it should do something like this, ride along the tracks until an station is approached, than the train brakes and comes to an halt at the station. It waits for 10 seconds to allow the player to enter/leave. Than it will accelerate to cruise speed towards the next station..And the sequence is repeated.

I'll need confirmation on that, with estimates for speed and waiting time at stations.

I'd just like to say thank you for attempting/working on the trains as I do seem to miss them.

Ok well perhaps somebody with GTAIII installed on the pc could extract the proper files as well as possible make a video file of both the subway trains and L-track trains for you. It would be better to see it in action then by description. I am one who is not good at judging speed but the train seems to accellarate faster then the banshee and the average stop time at the stops seems to be 18 seconds.

My intial statement of there being 4 trains seems to be inaccurate.
- There is only 1 subway train made up of 2 cars
- There is also only 1 train on the portland L-tracks made up of 3 cars

They each follow the track that has all stops on them.

Well,I'll try to et the portland Ltrack train running first.
One of the problems is that only 1 spathx.dat seems to be supported, but we might be able to string the different trainpaths into one file,and than use only the appropriate section, based on zones or something, but that later...

BTW. I'm doing this currently as a side project, ("Decoding the SAVEFILE" being my primary focus at the moment) so it might take some time, but I'll try to give regular updates here....

[ModelingMan]

Here's the original train files. (TXD is compressed)

It's great you are attempting to get the trains up and running. And no pressure, you can take as long as you need as we know you are doing an excellent job of "Decoding the SAVEFILE" and you wouldn't want to postpone that.

Hey i have GTAlll on PC and i could make a video of the train, i would just need hosting, and this i great idea, good work

[Craig Kostelecky]

Thank you, thank you, thank you Patrick. I was hoping somebody with your knowledge would attempt to figure out the train and subways. I'm really looking forward to seeing your work in action.

And special thanks to Mark for making the models.

[PatrickW]

@MM:
I´m now at IBM´s, following a 2 day RUP-course, but as soon as i´m home, I´ll try out your models..... thanx

@BCspeed34:
I would appreciate a small video of a train arriving en departuring a station, but it has to be small... ( I´m on a 56K6 line )

@Graig:
Happy to be of service, It´s time I do some real work for LC


Back to class, it great to be in class again
Class is cool, day-job suck

[ModelingMan]

Here's a little "station to station" capture from GTA3, it's just over 1MB with DivX 4.12 compression.

GTA3Train.avi (1.02MB)

[U Money $$$$]

You are a god modelingman

[Demarest]

I like Patrick. Know why? He's always like "how do you do this?" which is met with "can't be done" to which he says "oh yeah? watch this!" to which the audience must subsequently gather their jaws from the floor.

You should've made your username Juggernaut or something

[Craig Kostelecky]

That is one of the best descriptions (and probably most true) of any member I've seen made so far. I second every word Demarest said about Patrick.

[PatrickW]

You guys know how to boost up the priority of a job ...

And that coming from the Dem....
Feels even better than getting a karma-star.

You might be missing me for a couple of days.
My father-in-law went to a hospital with heart problems while he's on vacation is austria (i'm living in the netherlands). Depending on the information we get in the morning we'll need to go there to make arrangements and stuff and support mom.
[/serious]

[Demarest]

I SERIOUSLY hope all is well. Be there for your family; much more important for sure.

Although I wanted to say that I'm nobody in the modding community anymore. I'm old news now. You've not only decided to do this, but also hacking the savegames. Not only has that been dormant forever, but you've invoked some of the LEGENDS back into activity. You da man!

[PatrickW]

[personal]: We got a phone that everything is stable, so we will go there in the weekend, my brother-in-law is there now..
[/personal]

Yeah, it's great to see the LEGENDS back in action, and I'm honoured to be working with them...

It's just that I like doing new things.
For me modding is like solving puzzles. Once you know how a certain thing is done, it starts to loose its attraction.

But enough on me.....

I'll try to get the train-model on the track .....
