How to create offline version for CD?

Unity Engine
1

Hi,

I’ve been working on a project that requires delivery on a CD. The standard detection and install code for the unity plugin requires an internet connection. Is there an offline version available?

If not then I will have to attempt to create an offline version myself. Having looked at the code it would seem that I could replace the tDownloadURL variable with references to offline files.

        function GetInstallerPath () {
            var tDownloadURL = "";
            var hasXpi = navigator.userAgent.toLowerCase().indexOf( "firefox" ) != -1;
            
            // Use standalone installer
            if (1)
            {
                if (navigator.platform == "MacIntel")
                    tDownloadURL = "http://webplayer.unity3d.com/download_webplayer-2.x/webplayer-i386.dmg";
                else if (navigator.platform == "MacPPC")
                    tDownloadURL = "http://webplayer.unity3d.com/download_webplayer-2.x/webplayer-ppc.dmg";
                else if (navigator.platform.toLowerCase().indexOf("win") != -1)
                    tDownloadURL = "assets\plugins\UnityWebPlayer.exe\UnityWebPlayer.exe";
                return tDownloadURL;
            }
            // Use XPI installer
            else
            {
                if (navigator.platform == "MacIntel")
                    tDownloadURL = "http://webplayer.unity3d.com/download_webplayer-2.x/UnityWebPlayerOSX.xpi";
                else if (navigator.platform == "MacPPC")
                    tDownloadURL = "http://webplayer.unity3d.com/download_webplayer-2.x/UnityWebPlayerOSX.xpi";
                else if (navigator.platform.toLowerCase().indexOf("win") != -1)
                    tDownloadURL = "http://webplayer.unity3d.com/download_webplayer-2.x/UnityWebPlayerWin32.xpi";
                return tDownloadURL;
            }    			
        }

The only thing that causes me concern then is none availability of the cab file as defined in the embed tag:

            <object id="UnityObject" classid="clsid:444785F1-DE89-4295-863A-D46C3A781394" width="600" height="450" codebase="http://webplayer.unity3d.com/download_webplayer-2.x/UnityWebPlayer.cab#version=2,0,0,0">
                <param name="src" value="assets/VLE.unity3d" />
                <embed id="UnityEmbed" src="assets/VLE.unity3d" width="500" height="450" type="application/vnd.unity" pluginspage="http://www.unity3d.com/unity-web-player-2.x" />
                <noembed>
                    <div style="text-align:center;">
                        This content requires the Unity Web Player.[url="http://www.unity3d.com/unity-web-player-2.x"]Install now.[/url]
                    </div>
                </noembed>
            </object>

Will just replacing the download links enable this installer to install offline, or does it require an internet connection?

Thanks,

If you need a version to be run from CD - what prevents you from building a standalone?

If you need it for both Mac and Windows PC, you could simply do standalone builds for both. In general, I think standalones suit the CD-format significantly better than Web players.

Ah good point, thanks Jashan that makes much more sense!
