I'm just wondering if there was any way I could install this mod into my single player minecraft client so that I would be able to play a singleplayer world with this mod.
No. There's an important distinction between Multiplayer mods and Craftbukkit plugins. All SMP mods are automatically compatible with Singleplayer Minecraft and are installed in the same way, but Bukkit plugins are designed specifically for the custom server called Craftbukkit. Minecraft can only launch its own built-in server, so there's no way (I know of) to have it run Craftbukkit instead when you click "Singleplayer".
However, running craftbukkit locally is totally doable. It won't slow down your machine more than playing singleplayer normally does, because singleplayer runs a hidden server anyway. When you play on a local Craftbukkit server, Minecraft doesn't bother launching its own singleplayer server, so it ends up being the same amount of stuff running on your computer. Of course, you still have to set up the Craftbukkit server and install the Last Airbender plugin properly, but that's doable with some reading and learning. Once you have a multiplayer server running locally, you just use the Multiplayer button, add a server at the
There is a way to do this, using BukkitForge. This basically allows you to put Bukkit... inside Forge, the mod loader.
First, you have to install Minecraft Forge. This also allows you to install other Forge mods, like Computer Craft, Industrial Craft, and even more!
Now, install this by going to the download section, download the recommended version, and then copy the files in the zip into your minecraft.jar (instructions).
Run your Minecraft to make sure it works. Forge will set up, and then you should be good. Now it is time to install BukkitForge. Download
Place the BukkitForge file from before into this folder, and start Minecraft. It should start up normally. Now, go back into the
Now all you have to do is put your JAR file from the plugin you want to install into this folder, run Minecraft, load up a world, and bam, the plugin should work.
Have fun :)
Use the BetterLan mod: it lets you use Bukkit plugins in Singleplayer.
You can also use RealLan mod, but it will not support plugins, only add new commands.
