Onset 1.2.2

[Talos]

Onset 1.2.2 (Protocol Compatibility 3)

Client changes

Custom connect screen

The client can now display a web UI while connecting and downloading files from a server. The page to show is hosted on the game server directly and can be configured in the server_config.json.
This feature is optional.

Specifies the file/page to load in the web UI. Files are hosted in the public_html directory on your server. See WebUI load server content below to learn more about that.

"connect_screen_url": "loadingscreen.html"

Setting to enable the cursor. This could be useful for interactive loading screens.

"connect_screen_show_cursor": true

Replace animation sequences

You can replace default animations that are played by SetPlayerAnimation.

ReplaceAnimationLibrarySequence

With the new animation blueprint support you can also play custom animations directly in your animation blueprint. See the changes below for more information.

Custom animation blueprint support

Thanks to UnrealLua you can now load custom animation blueprints and assign them to a USkeletalMeshComponent.
For example you can add a post process anim blueprint to a player. The anim blueprint can contain any common nodes. Some useful ones are documented on the Unreal Engine Documentation page.
https://docs.unrealengine.com/en-US/...ols/index.html



To call a Blueprint function from Lua use the function ProccessEvent.

function SetPlayerAnimBlueprint(player)
-- Get the skeletal component for the body.
local SKComp = GetPlayerSkeletalMeshComponent(player, "Body")

-- Get the skeletal mesh of the component (body model).
local SKMesh = SKComp:GetSkeletalMesh()

-- Set a post process animation blueprint for the skeletal mesh.
SKMesh:SetPostProcessAnimBlueprint(UClass.LoadFrom  Asset("/AnimMod/CustomPP"))

-- Init anim again, this will create an instance of the post process animation blueprint.
SKComp:InitAnim(false)

-- Get the new animation instance.
local PPInst = SKComp:GetPostProcessInstance()

-- Call our blueprint function that sets the scale for our "transform modify bone" node.
PPInst:ProcessEvent("SetHeadScale", 2.0)
end

In this example we set a custom post process anim blueprint /AnimMod/CustomPP which runs after Onset's animation blueprint logic.
The blueprint has a function named "SetHeadScale" which sets the Testscale variable that you can see in the image above.

Documentation on the wiki will follow soon.

Throughout testing someone already created custom face animations.

Custom Discord Client Id

Servers can now set their own Discord Client Id. This enables the UpdateDiscordActivity to change things like image and text of the current session.
This requires to have a custom discord client id set in the server config.

"discord_client_id": ""

Discord activity documentation:
https://discord.com/developers/docs/game-sdk/activities

local Activity = { }
Activity.state = "Test"
Activity.details = "Test2"
Activity.timestamps = { }
Activity.timestamps.start_time = 1594231268
Activity.timestamps.end_time = 0
Activity.assets = { }
Activity.assets.large_image = "avatar"
Activity.assets.large_text = "Test"
Activity.assets.small_image = ""
Activity.assets.small_text = ""
Activity.party = { }
Activity.party.id = ""
Activity.party.size = { }
Activity.party.size.current_size = 0
Activity.party.size.max_size = 0
Activity.secrets = { }
Activity.secrets.match = ""
Activity.secrets.join = ""
Activity.secrets.spectate = ""
Activity.instance = false

UpdateDiscordActivity(Activity)

WebUI load server content

Currently there are two types of WebUIs. A local and a remote WebUI. Remote ones can load whitelisted websites. Local WebUIs can load content from packages.
With this release local WebUIs can now also load content directly from the game server.

Files must be inside the public_html folder. This folder is in the same directory as your OnsetServer executable.



From Lua you can now access the files:

SetWebURL(web, "http://server/index.html")

This allows to have dynamic web content without having to restart packages.
In the future I'm planning to integrate a CGI gateway to allow running PHP pages.

New vehicles

A new sports car, muscle car, golf cart and a truck with a towing area. The towing area was made by Erwann!



All vehicles: https://dev.playonset.com/wiki/Vehicles

New footstep sounds

Each floor type has received a whole bunch of new sound cues. Depending on your movement speed the sounds files also vary: "crouch", "walk", "run" and "sprint".

Remember you can influence which footstep sounds are played by having one of the following names in your materials.

metal, grass, concrete, gravel, ground, wood, carpet, sand, water, snow

A new event is called when a player hits the ground with their feet. You can return false to prevent the default footstep from playing.

OnPlayerFootstep(player, floor_type)

The floor_type can be the following: https://dev.playonset.com/wiki/FloorTypes

Lua 5.4 Update

The Lua library has been updated to version 5.4. You can read about the new features, which you can now use in Onset, on the official Lua page. https://www.lua.org/manual/5.4/readme.html#changes

UnrealLua API

New functions have been exposed that give more low level control over the game. One of the usage is shown above with the custom animations.
There will be more examples soon on how to use them.

In the meantime you can lookup the UE4 Documentation for their syntax.

Client side commands

Chat commands can now be added the same way as on the server using AddCommand.
The OnPlayerChatCommand event is being called before the command handler. If you return false in the even or in the handler the command won't be sent to the server.

Other changes
- Fix vehicle light toggle (switch) sound being too loud.
- Fix vehicle id 36/37 bright front light.
- Fix some vehicles not having proper damage in LODs.

- Add Epic setting for Ambient Occlusion and generally slightly improve the appearance.
- Add SetSoundRadius and GetSoundRadius for 3D sounds.
- Attempt to fix a crash with SetSound3DLocation.
- CreateSound now has an optional looping parameter. Has no effect on network streams.
- The maximum sounds playing was increased to 32. Useful for the soundstreamer in conjunction with vehicle sires.
- IsValidPlayer now returns true for the local player identifier.
- Fix CopyToClipboard function.
- Fix OnPlayerParachuteLand function.
- Voice is now activated by push to talk by default in the settings.

- Add OnPlayerToggleVehicleHorn which is called when a player presses the horn key. Return false to stop the horn from playing.
- Disable look up/down in first person when a non-layered animation plays. (From SetPlayerAnimation)
- Fix memory leak when Lua function references are destroyed. This was mostly noticeable when calling the Delay function frequently.
- Added pipes to the object list: https://dev.playonset.com/wiki/Objects
- Update Unreal Engine to 4.25.3.

Server changes

Update Lua to 5.4

Plugin creators are encouraged to recompile their project with the latest OnsetSDK header files and Lua libraries. https://github.com/BlueMountainsIO/OnsetSDK

You can read about the new features, which you can now use in Onset, on the official Lua page. https://www.lua.org/manual/5.4/readme.html#changes

Console Input

A new event named OnConsoleInput is called when a new input was confirmed with the ENTER key.

AddEvent("OnConsoleInput", function(input)
    print("OnConsoleInput "..input)

    if input == "quit" or input == "exit" then
        ServerExit("Exiting via console command")
    end
end)

The console can be disabled with the command line switch --noinput.

Other changes

- GetPlayerEquippedWeapon returned an incorrect weapon id.
- Add "discord_client_id" to the server_config.json.
- Update OpenSSL, Boost and Lua libraries.

- SetPlayer/NPCAnimation now optionally accepts an integer for the animation id.
- Add events OnDoorDestroyed OnNPCDestroyed OnObjectDestroyed OnPickupDestroyed OnText3DDestroyed.
