I just made a custom "instance" (no portal or anything) inside a cave. When I spawn mobs and go in with a level 15, I find that the mobs can aggro me from the other side of a cave wall! I was woundering how, or if, I am able to fix this problem. Not to be too demanding, but I dont want answers that just say "learn C++" or "learn LUA." If it is related to LUA or C++ then can you please either link or post a tutorial on how to do this, thanks a bunch!
EDIT: Also, I just have an EXTREMELY noob LUA question:
Say I make a custom boss (that doesnt already have a LUA script in the "scripts folder" of my repack) To make a LUA script for the boss, i just open notepad and create my script and save it as ".lua" in the scripts folder, then when i log in the script will work right? or do I have to execute it in a specific program or something? Thanks again!
