Changed: The internal concept of a ‘Server’ in Bolt is being re-named to ‘host’ to differentiate it from the ‘Zeus Server’, some APIs have been marked as deprecated and been replaced with ‘HostXYZ’ versions instead.
Changed: Updated the font and colors of the Bolt console.
Changed: Cleaned up large parts of the internal UdpKit API, this should not affect any public APIs but if you were compiling Bolt from source with your own changes UdpKit has been majorly re-worked internally.
Breaking: Most of the old and deprecated APIs have been removed, including the
Modify() syntax for states and the “using (var ev …)” syntax for events.
Breaking: Most method overloads which receives a
Bolt.IProtocolToken for connections and entities have been removed, you can now instead access the following tokens directly on the
BoltEntity objects instead:
This means that you have access to the protocol tokens for connections and entities at all times.
BoltShutdown callbacks have been removed and replaced with the following ones:
You can call the delegate passed into
BoltShutdownBeginand register your own callbacks which will be fired when Bolt has shutdown properly.
Breaking: The way Bolt runs it start-up and shutdown sequences have been completely re-worked, you can now call Shutdown/Start back-to-back and it will be handled properly. The new start-up sequence is completely asynchronous and happens in the background. You know if the start-up succeeded or failed based on the
RegisterStreamChannels callback has been removed, you should now register the stream channels in the
BoltStartBegin callback. You should also register any
Bolt.IProtocolToken classes in the same spot.
Breaking: The method signatures of
ConnectAttempt have all been normalized, they now all take both an
UdpKit.UdpEndPoint and a
Bolt.IProtocolToken as their parameters.
SessionConnectFailed has been changed to always take a
Bolt.IProtocolToken as the second parameter.
IState.GetDynamic for transform properties.

Changed: Several internal classes which were previously public have been made internal.
Changed: New properties added to states/objects will now default to the ‘Everyone’ replication setting.
Changed: The ‘Window/Bolt Engine/…’ menu has been renamed to ‘Window/Bolt/…’.
Breaking Change: The ‘MissingCommand’ callback now does not let you queue new commands, instead it assumes you execute any replacement logic inside of the callback itself. You will still get the last (if any) received command passed in as a reference.
Breaking Change: The ‘BoltStarted’ callback will now happen once the socket is fully started and bound, instead of right after the StartServer, StartClient and StartSinglePlayer call returns.
Fixed: Interpolation issue for floats where they would always come out as zero on remote peers is resolved.
Fixed: On transform properties position and rotation axes which are set to not sync will no longer be-overwritten with zeros.

Added: If you enable interpolation for floats you can now set it to interpolate as an angle instead of regular interpolation.
Added: If you enable compression on floats, ints or vectors their values will be clamped to the min/max compression values.
BoltNetwork.SetDedicatedServerInfo to complement
BoltNetwork.SetHostInfo, if you use
SetDedicatedServerInfo both Bolt and Zeus will assume that the server has correct port-forwarding setup and will never attempt NAT-punchthrough to it.
Added: You can now access the LAN, WAN and Socket bound endpoints through

Added: You can now manually set the UdpPlatform to use with BoltLauncher.SetUdpPlatform.
Added: All bolt arrays now implement the
Removed: The ‘accept token size’ setting has been removed (this setting was not used anywhere in the code).
Feature: The master server (named Zeus) is now available.
This is the first real public release of the 0.4.x series of Bolt, mostly due to time constraints caused by starting up Bolt as a full time company over the fall. Before this release 0.4.x has only existed inside the GitHub repository, but from now on all releases will be done on the website.
There are a lot of changes from 0.3.x to 0.4.x and the first part of the release notes are for the broader 0.3.x to 0.4.x changes, while the second part is for the specific changes on 0.4.1.7.

isOwner– Returns true if this entity was instantiated on the current computer.
hasControl– Returns true if you have control over this entity.
All other properties, including
isProxyhave been removed.
Feature: You can now toggle network simulation with a checkbox from the ‘Bolt Settings’ window, allow you to save your simulation settings but playing without wiping them.
Feature: The max packet size is now configurable via the ‘Bolt Settings’ window, do not touch this if you are unsure of what it does, a higher number is not ‘better’ than a lower number, allowed values are 1024 – 4096 (1kb to 4kb).
Feature: Added the ability to toggle of the assembly checksum check, there’s a checkbox to the right of the checksum that disables it.
Feature: Bolt now comes with a brand new installer, after unpacking the package into your main project run Bolt/Install Bolt from the menu and Bolt takes care of the rest.
Fixed: Fixed several small bugs with the
BoltGlobalBehaviour attribute, it should now work properly in all different configurations.

BoltMapNames has been deprecated.
BoltMapNames and is a public static class with const fields on it.
Changed: BoltPrefabs is now a static class with
const fields on it, instead of an
Changed: Map loading has been re-worked, in general it works the same way but the internal workings have been change to eliminate a bunch of subtle quirks. The callbacks for map loading have been changed and renamed to more clearly symbol what they do, the new callbacks are:
MapLoadLocalBegin(string map): Called when a map is begining to load locally
MapLoadLocalDone(string map): Called when a map is done loading locally
MapLoadRemoteDone(BoltConnection connection, string map): Called when a map is done loading on a remote computer, called for both the server on the clients and for all clients on the server.
Changed: Reworked the way BoltLog works, you can now implement your own class that inherits from
BoltLog.IWriter to provide custom logging functionality. Bolt comes with four default loggers: Unity Console, System Console, File and Bolt Console.
Changed: The window previously called ‘Bolt Connections’ has had it’s look and feel updated and is now called ‘Bolt Remotes’, more features will be added to this window in future updates.
Feature: Reworked the asset editor GUIs with a new style.
Feature: Bolt can now replicate mecanim layer weights, toggle the ‘Replicate Layer Weights’ checkbox on your Bolt mecanim asset to enable this.

Feature: Bolt will now make sure that two peers connecting to each other are using the same application guid and that their bolt.user.dll assembly has the same hash value.
Feature: Bolt now allows you to use a session wide unique id for your entities, enable this by checking the ‘Use Unique Ids’ option in the ‘Bolt Settings’ window, each BoltEntity now exposes a property called ‘uniqueId’ which is gurantueed to always be unique. Find a BoltEntity by it’s unique id using
Feature: You can now set the instantiate and destroy functions bolt should use with the new SetInstantiateDestroyCallbacks method on the BoltNetwork class.
BoltNetwork.Connect has gotten a new parameter called “token”, this is a byte array of size of up to 768 which gets sent from the client to the server when it’s connecting, if you are using manual connection acception this allows you to inspect the token data before hand and do things such as user authentication and verification.
Feature: You can now disable Clients from being able to instantiate certain bolt entities, on the Bolt Entity component you can toggle this on and off on a per-prefab basis.
Fixed: Android projects should now compile properly again.
Fixed: iOS projects should not crash with an AOT/JIT error anymore.
Fixed: Compilation errors in the startupshutdown sample is gone.
Fixed: Quaternion properties should now replicate properly.
Fixed: You can now enable interpolation for Vector2, Vector3, Vector4 and Quaternion.
Fixed: unsigned 32 bit integers of 9-16 bits should now replicate properly.
Fixed: InScope should not crash anymore when you destroy an entity on the owner.
Fixed: Numerous other small quirks and bugs.
Changed: Bolt will now load less prefabs into memory while looking for entities and assets to compile, this should speed up compilation and allow for compilation of very large projects without any issue.
Changed: BoltMapAsset are gone, Bolt does not use the “Map” asset at all any more and instead just deals with scenes like Unity does.
Changed: BoltConfigAssets are gone, Configuration is now done through the new ‘Bolt Settings’ window which you find under Window/Bolt Settings.
Changed: BoltEditorSettings are gone, it has been merged into BoltRuntimeSettings.
Changed: BoltClearScene is gone, it is not required any more.
Changed: The ‘Map Launcher’ window has been renamed to ‘Bolt Scenes’. The auto-starter has been removed if you are using the free version of Unity. The BoltDebugNonPro scene is gone because of this.
Changed: BoltEntity has gotten four new properties to query the state of the entity, they are ment to replace the old isOwner, isProxy and isControlling.
BoltEntity.hasAuthority: is you have full authority over this entity or not.
BoltEntity.hasControl: if you can control this entity.
BoltEntity.spawnedRemotely: if this was spawned by someone else than you.
BoltEntity.isDummy: if you are neither authority or in control of this entity.
Changed: Android and iOS builds now always use native sockets. The native socket plugins will also install automatically when needed and the menu option for installing them is gone.
Changed: The UdpPlatformAndroid and UdpPlatformIOS have been merged into one class called UdpPlatformMobile.
Changed: The udpkit platform assemblies have been moved into the unity project at .cs files instead to once and for all rid any issues with compiling for different platforms.
Changed: Due to the growing size of the project, the source .zip has been removed from the main download package, we instead provide direct access to our private GitHub repository.
Feature: BoltConsole now exposes a properly called ‘writable’ which you can be set to false to stop the console from consuming so much CPU.
Feature: Bolt now allows you to accept/refuse a connection before it is established, set the Accept Mode property in the ‘Bolt Setttings’ window to manual. Override the ConnectRequest method on an object which inherits from BoltCallbacks, then call BoltNetwork.Accept or BoltNetwork.Refuse.
Feature: BoltEntityBehaviour now exposes a ControlGained/ControlLost callback methods which you can override.
Feature: Since you can no longer set a Server and Client object on the configuration asset (since its gone) we have added new functionality for having behaviours which instantiate with the server/client and specific maps. All you need to do is to mark any MonoBehaviour with the BoltGlobalBehaviourAttribute, you can then specify if you want it for the server and client – or both. You can also specify if it should only be created and available during a specific map. Check the sample projects in bolt/samples for examples.
Fixed: Mecanim parameters will not be set if the Animator component is disabled.
Fixed: Resolved exception thrown when a destroyed entity got a lost or delivered packet notifiication.
Fixed: Fixed an issue with the BoltConfig constructor which would cause unity to throw errors when access a configuration asset in Awake().
Fixed: Bolt will now correctly disconnect all connections when shutting down.
Fixed: Fixed several subtle quirks causing Shutdown to act differently depending on when it was called.
Changed: ShutdownDone has been removed from BoltCallbacks since it would never get called as all objects would be destroyed before the callback would fire, BoltNetwork now exposes a .NET event called “ShutdownComplete” which you can subscribe to. Note that after each invocation of the event it will clear it’s callbacks so you have to re-register them every time.
Sample: There’s a new sample in the bolts/samples/shutdownstartup folder which demonstrates a clean shutdown-startup cycle for both the client and server. To run it set up your build settings to that the scenes are in this order:
Run Bolt/Compile and then build the project like you normally would (not using the map launcher), and start as many instances as you want and connect them together.
Important: UdpKit source code is now included in the source package, note that this source code is under the same license as the rest of the Bolt package, it is not open source.
Fixed: The BoltDebugStartNonPro script will now correctly select the proper configuration file.
Fixed: Prefabs should no longer accidentaly be marked as Scene Objects.
Fixed: Resolved numerous issues in the native sockets code for mobile free users.
Fixed: Resolved an issue where uint32 and int32 values of 9-16 bits would not serialize correctly
Changed: Reworked the entire build system, it’s now a lot easier to build on both OS X and Windows. All build scripts and other tools are also bundled with Bolt now. The new system uses the F# FAKE build tool which allows for easier building of the entire project at once, run the Build.fsx script with FAKE. Requires Mono 3.4.x on OS X.
Feature: Local LAN/WiFi discovery is now available. A simple example is available in bolt/samples/lanbroadcast. The new methods available are:
BoltNetwork.EnableLanBroadcast(): Enables the lan broadcasting feature, call this on both the client and server.
BoltNetwork.DisableLanBroadcast(): Disables the lan broadcasting. When you connect to a server on the client this is called implicitly, on the server you have to call it yourself to stop broadcasting your session.
BoltNetwork.GetSessions(): Call on the client to get a list of sessions found on the local lan, note that this method allocates a new array every time you call it because the data comes from the UdpKit background thread.
BoltNetwork.SetSessionInfo(string serverName, string userData): Call on the server for setting a server name and custom data that is transmitted with it’s session broadcast, which can then be found on
UdpSession.UserData on the session structs returned from
GetSessions() on the client.
Feature: Two new overloads for
Raise(IBoltEvent evnt, IEnumerable connections) and
Raise(IBoltEvent evnt, params BoltConnection connections), this lets you raise a specific event on your own local machine and on the specified remote connections.
Fixed: Resolved an issue where the entity packer would sometimes throw an exception when you tried to teleport a character.
Fixed: The BoltDebugStart and BoltDebugStartNonPro scripts now correctly use the port you configured in the map launcher.
Fixed: The BoltDebugStart and BoltDebugStartNonPro scripts now correctly selects a proper configuration file.
Fixed: Resolved an issue where if you were rotating an entity and the delta value per frame was small enough the rotation would not replicate properly.
Fixed: BoltDebugStartNonPro will correctly handle if no map has been specified.
Fixed: Entity scoping now correctly takes into account where an entity originated from.
Fixed: When an entity is attached it will now be scoped right away for all connections, so that events can be sent to it directly after Attached() is done.
Fixed: BoltDefaultConfig is no longer linked to the ServerObject/ClientObject prefabs in one of the sample projects.
Fixed: Removed all dependencies on the sample projects.
Feature: Added a new method called “AttachedLate” on the BoltEntitySerializer class, you can override this method in your own serializer. The method will be called after all Attached() methods have been called on both the serializer and any entity behaviour, and after scoping of the entity has taken place.
Feature: Bolt will now display a warning in the Map Launcher if the “Run In Background” player setting is not enabled.
Fixed: Byte arrays now serialize properly.
Changed: The default space in the name of a new asset, ‘New State’ for example, has been removed.
Feature: You can now see the port the Map Launcher will try to use, and press “refresh” to get a new random port number.
Fixed: Bolt now properly asks you if you want to save the current scene before launching through the Map Launcher window.
Fixed: The Map Launcher should now work properly on Unity 4.5 on OS X.
Fixed: Debugging with breakpoints from Unity-MonoDevelop should now work properly, without either client or server crashing and with no timeouts. Tested on Unity 4.3.4f1 and 4.5.0 on both Windows and OS X. Note: If you are having problems with the editor or locking/crashing when you start with the debugger attached, try to attach the debugger from Mono Develop after the editor has started play mode completely.
BoltMecanimAnimator.CopyProperties has been removed as it served no purpose.
Removed: The configuration setting from the Map Launcher has been removed, if you want a specific configuration to your maps you should set it on the map asset itself instead.
Changed: The default connection timeout in debug mode is now 600 seconds (10 minutes), giving you a lot more time to debug before the client/server disconnects when one side is paused.
Changed: The origin of an entity is now replicated to all proxies also.
Changed: BoltEntity objects placed in the scene now attach in
Start() instead of
Awake() on the server
Changed: The BoltNetwork class now correctly exposes
Attach(BoltEntity entity) and
Detach(BoltEntity entity) for manually attaching/detaching an object from Bolt
Changed: The ‘invoking [event]’ message will now only be raised if the event is actually being received
Changed: Reduced the size of the package by converting textures from .tga to .jpeg
Feature: A new property type was added: Byte Array, this type can only be selected on events and allows you to send a normal byte array through an event, max length of array is 256.
Feature: The current version of Bolt is now displayed at the top of the Map Launcher window.
Feature: The current amount of assets requiring compilation is now displayed at the top of the Map Launcher window, with a ‘Compile’ button next to it
Feature: GNU/Linux support is now official, Bolt will now run properly in both normal and headless mode under GNU/Linux.
Feature: The BoltEntity component now has a setting called ‘Controller Prediction’ which should be on if you are using a controlling scheme which allows client side prediction and off if you’re not using client side prediction in your controller script. Note that this setting does not enable or disable client side prediction, it simply tells Bolt if this entity is or isn’t using client side prediction so that Bolt can adjust it’s internal state accordingly.
Feature: New sample with a third person character that can run around, get into cars, drive the cars and then get out of them. Other players can also stand on the cars while they drive around.
Fixed: Bolt will now properly save the current scene before starting through the Map Launcher.
Fixed: Default configuration doesn’t have 150ms simulated ping and 2% simulated packet loss anymore.
Fixed: Resolved a bug in the transform snapshot interpolator that would cause entities to stop updating their position when using a very low de-jitter delay and a specific timing occurred.
Fixed: Resolved a bug where you would sometimes execute the same command twice when you were controlling the an entity you were also the owner of.
Changed: Damping parameter on float properties on mecanim assets now use the built in damping functionality of mecanim instead of it’s own logic. This makes sure that animations replicated through Bolt produce the exact same result as animations played locally with mecanim.
Changed: Renamed the ‘Type’ setting in the event editor to ‘Target’, so it’s not confused with the ‘Type’ setting for properties.
Changed: Corrected the name of the file BoltGUII.cs to BoltGUI.cs
Changed: Non-state assets will not let you select the “Custom” property type anymore, as they are only supported in ‘State’ assets.
BoltRingBuffer<T> now implements
Feature: The BoltNetwork class now exposes a ‘serverTime’ property which on the server returns the local frame count translated to seconds. On clients it returns the estimated server frame translated to seconds.
Feature: The BoltEntity class now exposes a method called
SetOrigin(Transform origin), this method allows you to set the origin transform of an entity. Bolt requires the transform to be mapped to an integer value for serialization over the network, by default Bolt allows you to add a BoltOrigin component to your transform and then assign it a unique id. If you don’t want to use the BoltOrigin component and prefer to do the tansform to id mapping yourself you can set the two callbacks available on BoltNetwork called resolveTransform and resolveTransformId. See the new sample called ‘TeleportAndElevators” found in bolt/samples.
Fixed: TutorialPlayerMotor.cs script now correctly applies gravity to the character.
Fixed: Compiler can now handle paths with space characters in them.
Fixed: Disabling the built-in transform or mecanim properties in the state editor will not disable the rest of the properties below them anymore.
Fixed: The BoltNetwork class now correctly exposes the
Destroy(GameObject go) and
Destroy(BoltEntity entity) methods.
Fixed: Queueing an unreliable event that was raised on the server to all connected clients should now work properly.
Changed: Renamed several labels of settings in the state editor. ‘Mode’ on each property is now called ‘Sync When’. The ‘Once’ option on ‘Sync When’ is now called ‘Once On Init’. ‘Notify’ is now called ‘Changed Callback’, ‘Smooth Time’ on mecanim float properties are now called ‘Damping’, ‘Smooth’ in Float, Vector2, Vector3, Vector4 and Quaternion properties is now called ‘Interpolate’.
Changed: Removed the ability to accidentaly create new properties of the transform, mecanim and trigger types. This would break the state asset making it unusable.
Changed: All methods in the BoltStateTransformDeadReckoning and BoltStateTransformInterpolatedSnapshots are now public/protected and virtual to allow for easier extension of the classes.
Changed: All internal fields and properties in the BoltStateTransformDeadReckoning, BoltStateTransformInterpolatedSnapshots and BoltStateTransform classes are now protected or public, to allow for easier extending of these classes.
Feature: Added the ability to teleport entities to a new location, which gives a clean transition from the old to the new position without any interpolation. Two new methods called Teleport(Vector3 pos, Quaternion rot) and Teleport(Vector3 pos) are available on the BoltEntity class.
Fixed: Assembly references from bolt.dll and bolt.editor.dll pointing on an old version of udpkit.dll
