Need help understanding Metadata items using @SideOnly

[HoLyCoW]

I'm new to modding and I'm starting with 1.7.10 because I bought Wuppy's book (http://www.amazon.com/Teach-Yourself-Development-Minecraft-Hours/dp/0672337193).

 

Anyways, in the section that talks about creating multiple items using one ID by using metadata, he ends up using the IIcon object which uses @SideOnly(Side.CLIENT).

 

I understand the code and how it works, however, i'm a little lost in the understanding of how this works if I were to run this mod on a dedicated server. Can I run it on a dedicated server? Will the server crash?

 

According to diesieben07 and what he wrote here, it WILL crash.

 

How would I get this to run on a dedicated server then?

 

Any help in understanding this would be greatly appreciated.

 

Thanks

If you're using @SideOnly for any methods fields dealing with IIcon or anything related to textures/rendering then @SideOnly is good. Any of this sort of method will never get called on the server, so using @SideOnly will not cause any problems.

Why won't it get called on the server? I guess my problem is that I don't have ANY experience with client/server programming. Shouldn't everything that gets called on the client, also be called on the server?

 

Here's one method that he uses in the book:

    public void registerIcons(IIconRegister par1IconRegister)
    {
        icons = new IIcon[this.keyNames.length];

        for (int i = 0; i < this.keyNames.length; i++)
        {
            icons[i] = par1IconRegister.registerIcon(SamsMod.MODID + ":" + "key" + " " + keyNames[i]);
        }

    }

 

Don't the icons also need to be "registered" on the server too? How else does the server know what texture/icon goes to what item?

The vanilla Item class already has SideOnly (client) on it.  Redeclaring it isn't going to fuck up anything, and neither will leaving it off.  Nothing in vanilla code calls getIcon when running a dedicated server.  There is NO rendering code on the server, so all rendering related calls are client-side-only and marked as such.

Hmm, okay. Thanks for the info.
