There is a new parameter for the function CreateWebUI3D and CreateRemoteWebUI3D to set the sound falloff distance.



SetWebVolume(web, volume)

SetWebPitch(web, pitch)

The following events allow you to block certain input when you return false.

OnActionKey(EventType, ActionName, KeyName)

OnAxisKey(EventType, AxisName, KeyName)

New constants (enum). Used for the new On*Key events.

Client update

Add function EnableSnowParticles(bEnable)

Add function SetLandscapeSnowAlpha(Val)

Example usage:



The loadstring function now has a 2nd optional parameter for the package name. You can specify a different package where the code will be executed in.



For example you could create a console function that executes code in a specific package. In the above picture you can see the new snow function being executed in the package 'default'.

Code used:

Add two new constants to Lua.

_PACKAGENAME
Holds the name of the current package.

_ONSETVERSION
Contains the current Onset version as a string.

Example usage:

Add the following missing members of the Lua math table.


Example usage:

• Fix roof collision of the marketplace building.
  
• Fix scooter steer animation.
  
• Update WebUI.

Add missing Lua functions to the client.

• Fix C# context based registration process for commands.
  
• Number of function fixes for C#.
  
• Update DotNet runtime to 5.0.12.
  
• Fix bullet sync where bullets are not spawned on each client.
  
• Make CreateText3D rotation parameter optional.
  
• Add OnServerLoaded event.

Game

• Fix UCharacterMovementComponent not working with GetComponentsByClass
  
• Increase tow truck acceleration.
  
• Fix door model number 6 collision.
  
• Fix game freezes mostly happening in fullscreen mode.
  
• Fix ambient sound near the northern desert mountain.
  
• Fix tractor, van and news van body coloring.

Server

• Fix some Lua natives that broke due to C#.
  
• Fix reported C# errors (Thanks to DaskDarki).
  
• Fix crash on multi-dimensional tables.

• Add optional bSync parameter to SetObjectLocation/Rotation and SetVehicleLocation/Rotation. This parameter is true by default. Setting it to false updates the internal location/rotation of the entity but does not sync it to the clients. Useful for stuff like physics sync and attached vehicle sync for tow trucks.

The game compatibility has changed in this release. Server owners must update their server via steamcmd in order to allow clients to connect.

Onset now features C# as a secondary scripting language.

Why C#?
Lua hits its limits when it comes to large projects. Becoming difficult to keep track of structure due to it's missing type safety and limited OOP. Onset is and was always about learning and having fun coding. C# is a popular and stable language loved by many.

Will it split the scripting community?
It might cause distraction to some extent but the C# implementation and Lua work very well together. You can mix both in a package and also communicate between the two languages. In the end we think the pros will surpass the cons.

In this version only the server has C# support. The client will follow in one of the next updates.

To get started take a look at the documentation. Remember it's still in experimental state. Things can change a bit until the stable release.

C# Developer Wiki

A big thank you to DasDarki for working with me on the implementation. For his efforts he received a special rank on our Discord server.


The landscape material has been replaced to offer better variation and tiling at large distances.

Vehicles added for apocalypse servers. Ids to spawn: 59 & 60.




Several improvements have been made to the vehicle handling.
Vehicles no longer get unstable at high speeds. Steering is more attached to the road. Generally the vehicles feel much heavier now. Acceleration has been adjusted accordingly.




Many bushes and smaller trees can now be run over by cars. This feature can also be added to vegetation on custom maps selectively.




The vehicles camera now follows the car while driving. You can still move the camera freely with your mouse. The camera will reset behind the vehicle after a few seconds if there is no mouse input and while not standing still.




The wiki now finally has been updated to reflect all of the games Unreal functions showing their proper signature. There will be more usage examples too.

Sandbox option

Add a new option named "sandbox" to the server_config.json. (Disabled by default)
Turning this on will enforce the same script security boundaries as on the client. For example no loading of compiled Lua scripts or usage of possible dangerous functions.

• Fix BroadcastRemoteEvent parsing parameters incorrectly.
  
• Fix crash when checking vehicle passengers.
  
• Fix GetStreamedPlayersForPlayer not returning players that are inside a vehicle.

Until now remote WebUIs could only display websites that have been whitelisted in the game config.

To give you more freedom, servers can now request the client to whitelist additional domains. Only domain names with a top level domain (TLD) can be whitelisted.

Use the new function AddWebUIWhitelist in your index.lua or any other package script. When a player connects they will be asked.



Example whitelisting from the above picture:

The following Lua event is called in your scripts once the player reacted to the request screen:



The following Javascript functions are now called in your custom connect screen.



Saving data on the client can be useful for some client settings. For example the ordering of an inventory in your UI.

Saving variables:

Reading variables:


Spawnable using the function CreateVehicle with vehicle model id 56.

• Fix crash in exported functions where returned tables contain functions.

Each package can now register package files and scripts in a special Lua file. The index.lua is executed before the server loads the package.json file. In this Lua file you can register scripts and files to this package.

The following functions are only available to the index.lua script. Besides that, only Lua library functions are exposed the index.lua but no other Onset server functions.

• AddServerScript
  
• AddClientScript
  
• AddSharedScript
  
• AddFile

Example for an index.lua script:

For the package to work, there has to be either an index.lua or a package.json config file. Both at the same time are also supported.


To autostart packages place them into the folder "autostart" where your OnsetServer.exe is located. If the folder does not exist, create a new one.
Packages inside this folder will be started alphabetically before any other packages.

The function StartPackage will attempt to look for packages in the autostart folder first.


Besides the existing voice channel feature, a new function has been introduced that allows you to set the 3D range of a player's voice.
The range can't be greater than the voice distance set in the server_config.json.

To reset the voice range pass a value of 0.0 or less to this function.

Server:

Client:


The server_config.json and package.json can now have comments starting with // or /* */.
