If you don't have a goto after an animation, then when it reaches the end of it, it will just continue on to the code you have directly below it. In this case, it was continuing on to the death animation you have there, which I'm sure isn't what you want. Remember, unless you specifically want it to continue further down in the code, you need a goto. Nearly everything eventually needs to reach a goto, unless it is an end command to end the animation (like the death animation).

I don't know if I should or should not sometime rename gotorepeatattk. Many people don't realize at first that they still need a goto after it, that it is not a replacement for a goto. I should probably at least add an additional note on it sometime in the opcode list.

It is probably a good idea to use another unit's iscript as a reference whenever you are adding a new animation, to see what you might need in the animation and to see if you might need any additional animations to go with it.
