Learning how to hack FE7. Need help!

[Xenomic]

Ok, so I've recently started trying to learn how to hack FE7 (I'd really like to do FE8 but I think I should stick with 7 for now. Just hope that one day manaketes will be easy to do in 7 ;__; ). I've started with eventing (because I always start with the harder ones!) and I generally understand how Units and Turn_events work. The only thing I'm trying to learn here with UNITs and Turn_events is how to change AI, which doesn't seem like it should be hard....

However, I am having a weird problem here.

Bad:
UNIT Batta Berserker Batta Level(30, Enemy, 1) [8,8] [8,8] [ironAxe, DelphiShield] GuardTile

Here, I have a Batta who is supposed to sit there and do nothing unless you're next to him, right?

TurnEventEnemy(0x0,BattaAttack,6)

In my turn events, I have this set so that on the enemy's 6th turn, it'll run BattaAttack.

BattaAttack: //This changes enemy's AI
CHAI Batta AttackInRange

ENDA

And here, it's supposed to change Batta's AI from GuardTile to AttackInRange (I'm making cliff notes for myself, as you can tell by the //. If anyone can help me with making cliff notes on various things, that'd be great and help me learn a lot faster).

However, despite having someone else test this and it working fine for him (Batta apparently does his thing of chasing after and attacking whoever is in range of him on the 6th turn), he...will not move ever for me. I do not know why. Is there something wrong with my Event Assembly?? Is there some other code that's interfering somehow? I don't know!

The entire document, for those curious. This isn't meant to be anything but cliff notes and experimenting with eventing to make sure I can understand this, in the event that maybe, MAYBE, someday I'll make my own hack (if I have a team only though...):

Hi Xenomic, a topic actually exists for event questions, so for future reference, please pop your event queries in there instead.

As for the events themselves, I did pick up an (unrelated) issue:

Tex1 0x0A8E //The convo part 1

You'll want to change this to TEX1.

Now, back to the question at hand: I hate to tell you that unfortunately in FE7 CHAI does not work the way one would expect it to and in fact it may not work at all. I don't believe any known way of making CHAI work properly exists for now--perhaps you could try a workaround like having a conversation with a background and then reloading Batta with the AttackInRange AI before fading back to the map instead?
