Well, hmmm... it's a bit long to explain, and it is actually just like adding a spellcasting animation except you're creating ground attack and air attack animations. Try reading over the tutorial I wrote for that, it teaches you a lot of the concepts about animations in IceCC, and by the time you're finished you should have a good idea on what to do, even if you don't know the exact steps:

1. Extract the code for the Gantrithor using IceCC.
2. Write the code for an attack animation. Make sure it has the usual fixtures of attack26, gotorepeatattk, goto <idle animation> and a block label.
3. Change the iscript header so that it points to your new attack animation's block label.
4. Recompile your iscript using IceCC, and add it as scripts\iscript.bin in your mod.
