I spent half an hour searching for a way to make the bats follow you all over the map.
All I found is that setting var[0] and var[11++] to 0 makes them chase you when you're close (and for some reason makes them shout while they're NOT awake and viceversa)
And setting these to anything else makes them NEVER chase you.
I also can't change their movement speed for chasing you.

I didn't want to bother you with more requests, but I can't do this by myself.

So, how do I give bats unlimited range? And how do I change their chasing speed?
