===Awesomium API===
===CEF===
====How to test====
*[[CEF_Tutorial]]
Install the latest installer from ('''run it as admin manually!'''): https://jusonex.net/public/mta/cef/
*[[Client_Scripting_Functions#Browser_functions]]
 
*[[Client_Scripting_Events#Browser_events]]
If it doesn't work, you'll have to install the x86 VC++ Redist 2013 (http://www.microsoft.com/en-us/download/details.aspx?id=40784).
*[[CWebBrowser]]
 
====How you can help====
The Awesomium branch needs a lot of testing before it can be merged into the trunk. This is the perfect way to help.
Especially the URL and javascript filter must work perfectly, so that you are not able to:
* read any file outside the MTA resorce directory
* load a website that is not explicitly allowed (by the whitelist or an accepted request)
* execute your own javascript code in ''non-local'' mode
 
====Local versus non-local mode====
'''Local:'''
* you can execute your own javascript code using executeBrowserJavascript/Browser.executeJavascript
* you cannot load websites from remote servers
* local mode is recommended for HTML UIs
 
'''Non-local:'''
* you cannot load local websites
* remote websites are filtered
* you cannot your own execute javascript code (javascript code execution on remote websites can also be blocked in the settings)
* non-local mode is recommended (and necessary) for extern websites such as YouTube
 
====Functions====
<syntaxhighlight lang="lua">
browser createBrowser(int width, int height, bool isLocal [, bool transparent = false] )
</syntaxhighlight>
*'''isLocal:''' Specifies whether to use the browser in local or global mode
*'''transparent:''' Should the browser support transparency?

====Examples====
Examples on: https://github.com/Jusonex/mtasa_cef_tools
 
=====Example 1: A 2D browser with mouse and a simple input handler=====
<syntaxhighlight lang="lua">local webBrowser = createBrowser(1024, 768, false)
requestBrowserPages({"youtube.com"})
focusBrowser(webBrowser)
 
addCommandHandler("load",
function()
-- Load the url
loadBrowserURL(webBrowser, "http://youtube.com") -- This line is potentially needless since YouTube is whitelisted
end
)
 
addEventHandler("onClientRender", root,
function()
-- Draw a nice border
dxDrawRectangle(195, 95, 1024+10, 768+10, tocolor(255, 255, 0))
-- Draw the browser
dxDrawImage(200, 100, 1024, 768, webBrowser)
end
)
 
addEventHandler("onClientCursorMove", root,
function(relativeX, relativeY, absoluteX, absoluteY)
injectBrowserMouseMove(webBrowser, absoluteX - 200, absoluteY - 100)
end
)
 
addEventHandler("onClientClick", root,
function(button, state)
if state == "down" then
injectBrowserMouseDown(webBrowser, button)
else
injectBrowserMouseUp(webBrowser, button)
end
end
)
 
showCursor(true)</syntaxhighlight>
 
=====A 3D browser at the car cinema in Fort Carson (Demo: https://www.youtube.com/watch?v=9w2qU6mZDh8)=====
<syntaxhighlight lang="lua">
local width, height = 1600, 900
 
-- Create the browser
local webBrowser = createBrowser(width, height, false)
 
-- Request the pages
requestBrowserPages({"www.youtube.com", "nyan.cat"})
 
addEventHandler("onClientRender", root,
function()
-- Draw the line
local x, y = 110.7, 1024.15
dxDrawMaterialLine3D(x, y, 23.25, x, y, 14.75, webBrowser, 18.2, tocolor(255, 255, 255, 255), x, y+1, 19)
