Web Player Failed to download the data file on WAMP (within php file)

Unity Engine
1

Hello, Unity community!

I am looking to have a game play in the unity web player on an educational social network website that I am helping to develop for a course of mine.

I am using the WAMP (windows apache mysql php) web development platform to run Buddypress.
I’ve added some test code as a plugin on the social network that you can see below.

I pretty much just copied the html code that unity generated and put it in the format that BuddyPress wants php plugin files to be in.

<?php
 /*
Plugin Name: unitygametest
Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
Description: Opens a unity web player and plays a test game

function unitygametest()
{
	//The UnityObject script has to be loaded before it can be used. 
	//This is done at the top of the <head> section. 
	
	//$unityWebPlayer_PorcufishPirates = 
	//'
	?>

		</body>
	</html>
	
	<?php
	//';
	
	//echo $unityWebPlayer_PorcufishPirates;
	
}

?>

Then I just makes sure the function gets called in the top level index.php file

if(function_exists('unitygametest'))
{
	unitygametest();
}

When I visit the site, the html that should run the plugin is ‘executed’ and the unity web player shows up to tell me that it “Failed to download the data file”

After doing some googling, I’ve noticed that some people needed to add the MIME type files to their servers.
So I found two mime.type files in my wamp directory and found the following:
application/vnd.unity unityweb

just to be sure, I changed it recognize/accept the .unity3d extension:
application/vnd.unity unityweb unity3d

That still didn’t work so I opened Apache’s httpd.conf and added this to the “AddType” section:
AddType application/vnd.unity .unity3d .unityweb

That didn’t change anything and I noticed that someone had gotten help on a similar issue by changing this line in the html:
unityObject.embedUnity(“unityPlayer”, “WebPlayer_PorcufishPirates.unity3d”, 960, 640);
into:
unityObject.embedUnity(“unityPlayer”, “WebPlayer_PorcufishPirates.jpg”, 960, 640);

which apparently fools the MIME type restrictions on certain servers.

But that didn’t make a difference.

I’ve also made sure that my .unity3d file is in fact named “WebPlayer_PorcufishPirates” as is called for in the .html file.
This same naming setup works just fine in the folder on my desktop that Unity generated when I first built the WebPlayer version. It only doesn’t work when I put the .html and .unity3d files in in the buddypress social network server’s plugin directory. Finally, I also tried generating a version with the UnityObject.js file and putting that down in that with the .html and .unity3d.

I’m at my wit’s end with this.
Does anybody have any idea’s why it “Failed to download the data file”???

One common theme I have found throughout these forums regarding this error is that no one can solve the issue! This error is maddening!

Same error “failed to download data file”… changed the MIME settings by adding application/vnd.unity as the mime type and both .unity3d .unityweb as MIME extensions. No change, still getting error.

I was facing the same issue and a similar configuration (XAMP using Elgg as the social network). Here’s what worked for me:

add

<?php $webplayer_url = elgg_get_site_url() . '{local path to .unity3d file}/WebPlayer_PorcufishPirates.unity3d'; ?>

replace

unityObject.embedUnity(“unityPlayer”, “WebPlayer_PorcufishPirates.unity3d”, 960, 640);

with

unityObject.embedUnity(“unityPlayer”, “<?php echo $webplayer_url; ?>”, 960, 640);

The call to elgg_get_site_url() returns the remote site root, i.e. http://127.0.0.1:8000/, the rest specifies the local path from the DocumentRoot specified in the Apache config (httpd.conf). And make sure your url variable has forward slashes.

Hope this helps ;).
