Hello

 

I'm currently working on a server mod which beside others allows you to show your players inventory on an Android device. To show the items in the app, I want to use icons from a texturepack.

The problem is, how to get the item's icon? My current approach is to send the the icons file name as it is in a texturepack (e.g. apple.png or book_enchanted.png) to the app, which can take the image from its own texturepack.

My question is how can I get the item's icon's file name? The class Item has a protected method getIconString(), which I could access with the dirty method of creating a new wrapperclass in the net.minecraft.item package, but, at least at server side, it only returns MISSING_ICON_ITEM_37_flower instead of flower_dandelion.png.

Do you have any idea how I could get the appropriate file name?

 

Thank you in advance.

You can get it via reflection, and dont edit the minecraft source

Ok thanks for the advice, I will try using that.

But this will probably not solve the problem that the iconString is empty on the server.

Anyone an idea?

I tried using reflection, but the field is just null on the server

 

Now I tried another way, since Items and Blocks have a method registerIcon or registerBlockIcon where they set their Icon in an IIconRegister, which then returns a IIcon. This method is not called on the server, so I simply call these methods with a fakeIconRegister, which returns the icon_file_String to me. That actually works, but now the aver block on which I call this method shows up with an undefined purple/black texture on the client (http://www.directupload.net/file/d/3547/w7qil68o_png.htm). This is probably caused by the FakeIIconRegister which return null as an IIcon and the client synchronizing it with the server (why ever).

The I changed the FakeRegister to return a new IIcon (a TextureAtlasSprite with the iconString as parameter in fact) instead of null, now the blocks and items show up as orange blinking blocks (http://www.directupload.net/file/d/3547/guo3k6hl_png.htm).

 

Any idea how to avoid this?

 

Thanks in advance!

 

Edit: I now abort the method registerIcon by throwing a null pointer. Almost everythings exept for any wooden stuff works now

 

Here my getIconString method:

private String getTextureString(Item i){
	FakeIconRegister register=new FakeIconRegister();
	try {
			try {
				ItemBlock ib=(ItemBlock)i;
				ib.field_150939_a.registerBlockIcons(register);
			} catch (java.lang.ClassCastException e) {

				i.registerIcons(register);
			}
		} catch (NullPointerException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	return register.getTextureString();
}

 

And my FakeIconRegister:

private class FakeIconRegister implements IIconRegister{

			String texture;
	@Override
	public IIcon registerIcon(String var1) {
		texture=var1;

		//Should throw a nullpointer
		String n=null;
		n.charAt(1);

		return createTextureAtlasSprite(texture);

	}
	public String getTextureString(){
		return texture;
	}

	private IIcon createTextureAtlasSprite(String s){
		try {
			Class<?> c = TextureAtlasSprite.class;
			java.lang.reflect.Constructor constr=c.getDeclaredConstructor(String.class);
			constr.setAccessible(true);
			return (IIcon)constr.newInstance(s);
		} catch (NoSuchMethodException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SecurityException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InstantiationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalAccessException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InvocationTargetException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return null;
	}
