tip

Notre implémentation WebUI est construite en utilisant les dernières versions de Chromium Embedded Framework.

tip

To access the in-browser remote debugging head over to http://localhost:9222 when you are connected to a server.

Proprietary Codecs

Proprietary Codecs like MP3 and AAC are not supported on public CEF builds. We recommend converting your media files to WEBM or OGG.

🎒 Examples

Client/Index.lua
-- Loading a local file
local my_ui = WebUI(
"Awesome UI", -- Name
"file://UI/index.html", -- Path relative to this package (Client/)
WebUIVisibility.Visible -- Is Visible on Screen
)

-- Loading a Web URL
local my_browser = WebUI(
"Awesome Site", -- Name
"https://nanos.world", -- Web's URL
WebUIVisibility.Visible -- Is Visible on Screen
)

-- Loading a local file from other package
local my_ui = WebUI(
"Awesome Other UI", -- Name
"file://other-package/Client/UI/index.html",
WebUIVisibility.Visible -- Is Visible on Screen
)

Using a WebUI as Mesh Material

Client/Index.lua
-- Spawns a WebUI with is_visible = false, is_transparent = false, auto_resize = false and size of 500x500
local my_ui = WebUI("Awesome Site", "https://nanos.world", false, false, false, 500, 500)

-- Spawns a StaticMesh (can be any mesh)
local static_mesh = StaticMesh(Vector(0, 0, 100), Rotator(), "nanos-world::SM_Cube")

-- Sets the mesh material to use the WebUI
static_mesh:SetMaterialFromWebUI(my_ui)

Communication entre Lua et JS (WebUI)

Client/Index.lua
local my_ui = WebUI("Awesome UI", "file://UI/index.html")

local param1 = 123
local param2 = "hello"

-- Calls a JS event
my_ui:CallEvent("MyEvent", param1, param2)

-- Subscribes to receive JS events
my_ui:Subscribe("MyAnswer", function(param1)
Console.Log("Received back! %s", param1)
-- Will output 'Received back! Hey there!'
end)
script.js
// Register for "MyEvent" from Lua
Events.Subscribe("MyEvent", function(param1, param2) {
console.log("Triggered! " + param1 + " " + param2);
// Will output 'Triggered! 123 hello'

// Triggers "MyAnswer" on Lua
Events.Call("MyAnswer", "Hey there!");
});

// It is also possible to unsubscribe from an event to make it stop triggering
Events.Unsubscribe("MyEvent");

Belle barre de défilement

Since we migrated from Webkit to CEF, some scrollbars got ugly. Here's a small CSS snippet to make them almost like the Webkit ones:

::-webkit-scrollbar {
width: 6px;
}

::-webkit-scrollbar-thumb {
border-radius: 10px;
background-color: #494949;
}

body {
scrollbar-gutter: stable both-edges;
}

You can use the output Texture from a Canvas with :SetMaterialFromWebUI() method!
