Train, Rail and Roller Coaster System

[apoisonedgift]

This looks awesome! I have no need for this in any of my current game projects, but I want to pick it up just to play with it haha! Nice work.

This is exactly what I wanted and it has even more features than just that. Can't wait for it to be available!

Does it support magnetic levitation tracks too ? It is current tech that does exist. Is it possible to have your system replicate that and then just add custom tracks and train meshes ? I would need that for sci-fi levels and I would like to be able to have control over levitation parameters like having the train levitate a lot higher on the tracks compared to current tech for example.
And could it be possible to have "ghost tracks" for the railroad? I mean to design and assemble tracks that then remain hidden so that the train meshes run on a railroad that is just not there but still following it properly? So like having trains floating in air too like there was a track there but only in-editor such track would be viewable/editable.

In the Unreal live stream they mentioned you want ideas. After noticing in the marketplace I immediatly thought I need to setup a rail turret system so maybe some thought into a basic projectile example would be interesting. There was a similar type of turret created for one of the Unreal Tournament games.

my next question is "when is this coming"?

Thanks DasMatze, when we first wanted to add a train to our prototype, we thought we'd have it in and running in a couple of days... Nope. After some searching and research we came across your topic and a few others of people all looking for the same thing.
So we decided to build a solution. We did some physics prototypes, which were interesting, but didn't really work out, and there's no way people would use them. We might put together a blog post or postmortem on everything we went through, I'm sure someone will get something out of it.
But topics like yours were invaluable when starting this project, so we hope you enjoy the end project and that you get what you need from it for your project. When you've had a chance to try it out, please send us your feedback, or if you need something more from it, shout.

Does it support magnetic levitation tracks too ? It is current tech that does exist.

Yes, 100%, trains come with a mountain of options to adjust the look and feel (check the doc link for full list), including offsets on the track, so you can have it float above the track to create a mag rail effect.
You could even take it one step further and change the speed calculation function in blueprint so that as the speed reaches 0 or the power to the track is decreased the offset is decreased and the train lowers down, if you want to create a fancy effect.
See the screenshot below for a screen of the sample maps showing the offsets in the carriage setup example map that's included.

Is it possible to have your system replicate that and then just add custom tracks and train meshes ?

Yes, please see the previous posts for answers on replication.
Yes, the meshes provided are for example only, you can change the meshes to anything you want, all are exposed via blueprint to make things easy.

And could it be possible to have "ghost tracks" for the railroad? I mean to design and assemble tracks that then remain hidden so that the train meshes run on a railroad that is just not there but still following it properly? So like having trains floating in air too like there was a track there but only in-editor such track would be viewable/editable.

Yes, the tracks are built on splines, so you can disable the track mesh and any other visual option you want and the train will still follow the track and work as expected.

The whole thing has been built so you can change it to anything you want; mag rails, ordinary trains, roller coasters, convener belts, anything that moves along a track, you should be able to build with this.

In the Unreal live stream they mentioned you want ideas. After noticing in the marketplace I immediately thought I need to setup a rail turret system so maybe some thought into a basic projectile example would be interesting. There was a similar type of turret created for one of the Unreal Tournament games.

Indeed we are, so thanks for taking the time to make a suggestion. Are you suggesting that the turret is mounted on rail so it can move around?

my next question is "when is this coming"?

We are just waiting to hear back from Epic about the release date, as soon as we have that, we'll update here and on social media.


Thanks for all the questions, it really is excellent to see people this engaged, please keep the questions, comments and suggestions coming.

Thanks,

Something like this could be very interesting.

Quick update; The system has been approved and we are waiting for a release date. Big thanks to Epic and the marketplace team for helping us get it setup.
We'll update this thread and the OP once we have a release date.

Can the cars simulate roller coaster physics?

Could you elaborate on your question?

I think [MENTION=434]BrUnO XaVIeR[/MENTION] refer things like: Gravity, Inertia, acceleration and deceleration. And probably something like avoid Gimbal Lock using blueprints only.

Yes, this is exactly how the system works. Check out the first post for full details on the features. You can also see some of these features in action in the video.

There are two engine settings:
- Acceleration, weight, friction, gravity all work as expected and are customizable. Trains will slow down as they go up a hill, or speed up as they come down a hill. There is a whole demo map dedicated to this and a map on roller coasters.
- Constant speeds, here the train will always move at the same speed.

Hope that clears things up, shout if you have any more questions.

this is awesome, or this is awesome? i can't decide ^^

Looks original and cool, gg
