Is Application.dataPath broken?

Unity Engine
1

Hi

Anybody tell me what is wrong with this code please?

var bannerFile = "/banner01.jpg";
private var bannerPath = "";

bannerPath = Application.dataPath + bannerFile;
	
function Start(){
    var www : WWW = new WWW (bannerPath);
    yield www;
    gameObject.renderer.material.mainTexture = www.texture; 
}
  • I have confirmed that banner01.jpg is in the exe path and works fine if used manually.
  • This is a standalone windows exe build
  • The banner texture always comes up as a red questionmark which I assume is not found.
  • I have output the result of bannerPath and it does indeed point to the file

Cheers for any help.

After much hair pulling I decided to hard-code the path which works fine.

Shouldn’t you use \ instead of /, for stand alone ?

Just my little share, and my little thoughts :slight_smile:

I had same problem. In Unity 3 “Application.dataPath” have to be in function so you need move it to Start or Awake function :wink: When you read error message it will be there.

The issue is that the WWW class uses a different protocol.

Application.dataPath returns C:/… or /… whereas WWW looks for either file:/ or http:/ for it’s beginning extensions.

To convert a path to something WWW can use I use:

string file = Application.dataPath +  filePath;
		
		//Catch for Windows path formatting
		if(file[0] != '/')
		{
//Windows style
			file = "file" + file.Substring(1);
		}
		else
		{
Mac Style
			file = "file:" + file;
		}
		
		WWW import = new WWW(file);

Edit: Using file is for accessing local resources.
