[Released] Bolt, The new generation of networking solution for unity!

​

Bolt is a new generation of networking middleware for the Unity3D game engine. It revolutionizes development of multiplayer games in Unity by exposing several complex features behind a simple to use visual interface. Bolt allows you to replicate both transform and mecanim animations automatically, but on top of that it also allows you to define your own state properties which too will be replicated automatically for you across the network.

Features

Powerful Event System - Bolt has a built-in event system which automatically distributes the event to the correct receivers, highly configurable of course. Events can also be targeted at a specific game object or globally. Three delivery modes: Unreliable, Unreliable Synced and Reliable.

Authoritative movement - Built-in support for input and player controller state synchronization allows you to easily implement custom authoritative movement that suits your game.

Both dedicated and listen server - Bolt supports both the classic dedicated server and listen servers where the server is just another player.

Prioritization and scoping - Bolt supports both scoping of entities (which entities should a player be aware of) and prioritization of scoped entities (of two entities A and B that are scoped, which one is the most important for a player).

Hit-box recording - Bolt has built-in support for recording hit-boxes and rewinding and ray-casting against them, allowing you to implement complex techniques like lag compensation in first person shooters in just a few lines of code.

Synchronized map loading - Bolt support loading maps from the server and have all the clients load the same map, and then provide custom hooks telling the server when the client is ready and vice verse.

Full source code - Bolt comes with full source code, including all project files and other utilities for modifying and building Bolt binaries yourself.

Supports all major unity platforms - Bolt runs on Windows, OSX, iOS and Android. Support for Linux and Windows Phone 8 coming soon.

Does not require Unity Pro - Bolt does not require Unity Pro for any platform and will run without problems on the free iOS and Android version of Unity.

Information

Want more information on how bolt works and what you can do with it? Check out our lengthy tutorial over at http://www.boltengine.com/Tutorial.aspx or our API documentation http://www.boltengine.com/Api.aspx.

 

hi,

Would this be easy to get working with company firewalls/proxies..?
(we have tried photon cloud, but cannot get it to connect..ports are open, but there is no clear info if/what else is needed to open/allow..)

and is the beta price still available in asset store?

(also, some kind of lobby demo scene or tutorial could be nice..to save some time)

 

We are launching NAT punch through before the final version goes live, but sadly company firewalls and proxies are notoriously difficult to handle since they often block *everything*, it's a case-by-case basis if it works or not.

The price will be the same in the asset store, yes. We are waiting for the asset store approval process.

There is a long tutorial on the main site, www.boltengine.com which goes through everything there is to know about Bolt top to bottom.

 

This looks pretty cool. I'm going to have to start digging into the docs.

 

Hey looks promising.

But is there any authorative movement Demo? As I found no documentation about it. Would prefer some information before buy .

 

There is a huge tutorial which can be found on www.boltengine.com: http://www.boltengine.com/Tutorial.aspx The movement implemented there is example of an authoritative setup, specifically this section http://www.boltengine.com/Tutorial.aspx#Ownership__Replication___Control

 

Okay thanks. Gonna order it later when at home.

 

It is looking really really great fholm - as soon as i get some more time on my hand i will certainly buy it and play around with it.

 

Thanks, I hope you'll get some good use out of it

 

this look really great, the inspector, the callback methods, the demo scene, you raised the bar high and left tnet and photon far away.

will you provide a generic server executable?

will you manage with built in functions pooling/spawn/despawn?

do you have something equivalent to room and player custom properties from photon?

any roadmap?

 

Thank you for the kind words

Bolt is intended to run both the server and client inside of Unity, maybe in the future we could look at building an external executable.

We intend to expose the internal create/destroy mechanism so that you can plug any pooling system into Bolt and use whatever you want. This is one of the first things on our "TODO" list, and it will be ready in a few weeks.

Bolt doesn't have the concept of a 'room', so nothing there. For player properties you can just spawn a separate prefab entity in bolt without a model, etc. and turn of the transform and mecanim replication and just define your own properties there, which will be synced to all others connected.

 

This look like a nice network solution, do you think streaming using this system http://forum.unity3d.com/threads/247647-Asset-Store-Asset-Streaming-Plugin would be possible using your network assett?

 

I see no reason that the streaming system would not work with Bolt, as long as all the network prefabs are in the main executable/non-streamed part, it should be fine.

 

will you provide a way to define region ?
like player A and B are in region (1: it has monster 1A) player C is in region (2) A and B and monster 1A receive mutual sync but not C

 

Currently you would have to define this yourself by overloading two methods called InScope and CalculatePriority on the BoltEntitySerializer object which lets you do completely custom scoping and priority.

We are planning to have a pre-packaged solution for this before the final release (which is scheduled at some point in august), so you can define regions in your scene and calculate PVS data for it.

 

Woo!!
Bookmarked. Congrats for the release.
BTW, you should keep the link to your GitHub in your signature.

 

Any smart solution for load-balancing on the road map?

 

"Synchronized map loading - Bolt support loading maps from the server and have all the clients load the same map, and then provide custom hooks telling the server when the client is ready and vice verse."

What database solution does this use like mysql?
What method do you us to save data?
How will this support player created maps? Saving and loading them?

 

I think I've been unclear with this text, bolt has a concept called "maps" in tandems with scenes, this simply lets you load a scene in a specific way which makes sure it is synchronized on the server and all clients. It has nothing to do with mysql, databases or player created content.

 

Great to see your knowledge on networking is being put into a complete server,
any info yet on the CCU it can hold ?

 

Pretty sure that will depend on the requirements of the game (on the server side)

 

Bolt is now available on the asset store : https://www.assetstore.unity3d.com/en/#!/content/18358

 

I thank you kindly for these words

Like BFGames stated this depends heavily on your game, since Bolt allows a very high degree of configuration for different send rates, prioritization schemes and compression levels. The tests we have been running during our closed alpha tests have been with 2 to 128 players, with varying levels of game complexity.

There is a sample in the bolt package called 'prioritization' which demonstrates how the priority algorithm can be used, it synchronizes 128 moving spheres to all connected players using about 20kb/s per player, that is 150 bytes/second per sphere (which has position + rotation synced), which is very low - but can be pressed even further down depending a bit on what level of accuracy you need on positions, the lowest we have gotten is about 90 bytes/sec per entity while still retaining a playable simulation.

 

I am a noob at this, so this is proberley a very basic problem. But when I follow the instructions and get to the first Bolt compile point I get a lot of CS2001: Source file ´\Temp\bolt\xxx.cs´ could not be found.

The files are there at the correct locations.
What am I missing? I have tried to start a new project and reimporting bolt a few times without luck

 

What platform are you on? And could you copy the complete error message (and all of them)?

 

My platform is 4.3.3 free, I am updating it now to see if it helps

 

4.3.3 should be fine, its what I developed Bolt on. I should have been more clear, I meant what OS you are using (what version of it), and also if you can give me the FULL path on disk to your project? It looks like something in the path-resolver isn't correct in Bolt.

Hi fholm
I solved it
The project name must not contain spaces like in my project name "New Unity Project 19"

 

Ah, but it's definately a bug in bolt and I will make sure this gets fixed, thank you!

 

I will be definitely picking up this and evaluating it for my next project, pretty much any time I've see you talk about networking you're well informed.

Any plans for standalone in the near future?

 

Thanks for your kind words

There's been a few requests for this, and my feelings on it are mixed at best. First of all what sets bolt apart right now is that it can do so much automatically for you (transform, animation, authoritative movement, etc.) and the reason it can do this is because of everything on both server and client existing inside Unity. Secondly, there are already so many good unity stand-alone server solutions available, I don't see the need to throw Bolt into the ring.

However, we are planning to make a "forward" server that you can host yourself, allowing you to setup the same architecture as Photon Cloud where you have a "dumb" server which forwards data between players, and maybe perform some more things like authentication, etc.

 

Hi fholm,
Thanks so much for releasing this. I've purchased it and have gone through the tutorial and am ready to start integrating it into a small project.

I have two things I want to ask you.

Firstly, I have a few bugs I've found while going through the tutorial, is there a good way to let you know about them (you might already know about these bugs, but just in case).
Should I post them in the feedback part of the boltengine.com website or here?

Secondly, in the project I am making players are children of ships which are moving in the world (so the "world" is non-static).

I have solved this in my tests with basic Unity3d networking by syncronising the local position and rotation of players rather than their global position/rotation, and the world position/rotation of the ships they are parented to.

Is there any way I can request a checkbox be made for Transform state sync to use the local properties and not the world properties on a State definition?
Alternatively if I do the state replication myself, is there any code I can access to do interpolation of state info using the local position/rotation of entities?

Thanks again for this awesome library!
Alister.

 

THInteractive: The best way to submit bugs is to do it on http://feedback.boltengine.com/, through the "Contact Support" link. Or you can click on the little "Speech-Bubble" with a question mark in it on the www.boltengine.com site directly.

About the local position thing, I will be releasing a new version of bolt today which fixes a few bugs here and there, what you are asking for (local vs. world position) is a very quick fix, so I will make sure to include that in the update later today so you don't have to do any codeing yourself.

But, on the topic of synchronizing a bit more complex data, you can create a custom class which inherits from "IBoltStateProperty", and implement all of the methods on it. You can then set a property in the state editor to "Custom", and then in the Attached(IMyState state) callback on the Serializer (which is the first Attached callback which executes) you assign your property a new instance of your custom class. Take note that you need to call PropertyChanged method on IMyState to notify the state that your custom/complex property is "dirty" and needs syncing. This is exactly how the existing transform and mecanim replication properties work.

Anyhow, I will make sure that there will be a World/Local switch on the transform property available to you within a few hours.

 

TH Interactive, I assume something like this is what you meant:



There is a new "Space" option, which lets you switch between World and Local

 

Like Rewinder?!

 

Amazing! You are a genius!
Thanks so much Fholm.
Yeah I was looking through the source code and sweating thinking.. how am I going to add this without ruining everything?!
Thanks again and I'll be sure to retest the new version and see if the bugs I found are still there before reporting them.

 

Yes, like Rewinder, but Rewinder is a generic implementation and the one in Bolt is specific to Bolt and works better with its internal structures. Also rewinder is getting removed as I feel I only have time to give support on one major asset (Bolt) and want to focus on it.

 

Hi Fholm,
Sorry to bug you again, but I was looking through the code for Bolt and I would really like to extend BoltStateTransformInterpolatedSnapshots for my player's transform but make some additions to it (particularly in AfterStep, BeforeStep, Pack and Read).
Is it possible to make them virtual for extending in the next version you are uploading, or would that have performance implications or other reasons why that wouldn't be a good idea/not possible?

 

I could make them virtual, and it wouldn't really matter as far as I can tell. You would have to extend it, and then set it yourself to an ICustomProperty field, and disable the default transform property. I made everything in both of the DR and InterpolatedSnapshots classes extendable by marking all methods as virtual and exposing all internal data as "protected" instead of private/internal.

I could also expose public event callbacks on the classes which would be something "OnAfterStep", "OnBeforeStep", "OnPack", "OnRead", etc. which way would you prefer?

 

Hi Fholm,
Yes I noticed that some parts were protected instead of being private, so that's why I asked
Both methods are great, and either will work for me, so please go with whatever you think is best and fits best with the library.

All I need is to be able to pack/read my own data before/after the transform does, and control the states internally for when the player teleports or changes ship (reparenting - for that I plan on clearing out previous lerping states, so that the player teleports cleanly to the new location).

 

I am leaning towards the inheritance approach, as it will give you full customization and the ability to override *any* part of it, there will be some thing that the events wont let you do for example.

I actually thought about this also right around now, that the world/local thing isn't fine-grained enough, and I would like functionality which lets you do SetParent(BoltEntity entity); and that the entity always is synced in it's parents coordinate system.

I will expose the IS/DR classes for you right now, and then I'll try to get the SetParent thing ASAP (maybe today also, but probably tomorrow).

 

Thanks Fholm, amazing as always!
Can't wait to get the next update and put it in what I'm building!

 

By the way, does this mean I can call SetParent() on the controller of the entity and it will cleanly set parent and new localposition through the network, to the proxies, or will I still have to hook it up with events to cleanly parent through the network?

 

That's the idea yes, that you'd call SetParent() on either the controller or the owner and that it will cleanly propagate through the network.

I also want to break the functionality into two different functions, first SetParent(BoltEntity parent) which we already talked about, and that sets/clears the parent of the object. And then to do the clean Teleport I want to simply to Teleport(Vector3 position). What this allows is that you can then use this for things like elevators and other things which shouldn't "teleport" you into them but simply re-parent you so that you move with them (but retain the same position in the world), and it also allows you to do what you want to do by "switching ships" and then teleport to a specific position on that ship.

 

Awesome, just what I need! Thanks!

 

It looks like I should be able to get both SetParent and Teleport in for tonights update, I'm not sure what timezone you are in (I'm in CET+1, Sweden to be precise) and I expect the update to land around 6-7 pm my time. (in about 6-7 hours, that is).

 

I'm in Australia, so GMT +10, so it should be ready for me for work tomorrow morning!
Thanks Fholm

 

I purchased Bolt a couple of days ago and I must say I'm very impressed, bit of a bumpy start but those issues have already been fixed in 0.2.0.1 and 0.2.0.2.

I tried the built in Unity networking and disliked it, I tried Photon and disliked it too due to having to jump through their hoops. I wanted a simple way to connect a server and a client directly, so I attempted to use UdpKit but never got very far as low level networking is not my strong point. Luckily Bolt came out and I purchased it straight away as it was a great price for what it promises.

I've followed through the tutorial and it all works great, there's been a few issues/bugs but Fholm helped directly to identify and fix them that there are now no issues. I have a working Dedicated Server <-> Clients environment and it works flawlessy, I've tested it over the internet with friends and I can't find any faults.

The automatic handling of serializing and syncing things like transform and mecanim are amazing, plus the fact I can configure it to synch whatever I want makes this a very powerful and high-level friendly approach to networking. My favourite part though is probably the custom Event system, it is very easy to set up an event to be sent and received wherever you like, on server and/or clients. There's really been a lot of thought in to the kind of things people would want from a networking solution.

As someone without the time to deal with low-level networking, Bolt is a must buy. You still get plenty of control in the code by being able to extend and override various classes functions. The compilation of your Bolt Assets into accessible classes/objects in the code is very developer friendly and intuitive. I'm very eager to continue my project to see what I can do with it

 

@mattmcg thanks for that review, you have sold it for me. Will definitely be picking this up.
