Well, I have been developing my Lua coding skills but remain at the bottom of the 'novice' scale., I'm afraid. :-(
I have been creating a level for my two youngest nieces (aged 7 and 9) which I am desperate to be ready (fully tested, working, fun and well-packaged) for Christmas. I still have three levels to create so the heat is on!
Anyway, the level I am currently working on is set in school. Obviously, school is no place for violence so I've made it a quest type game. As part of this I modified the stock fantasy character ai script so it would follow waypoints but basically ignore the player and, certainly, not attack her!
I am rather proud of my script and very happy to share is here (crude as it is). However, although it works flawlessly in all levels I have designed to test it, it does not work properly in the very level for which I created it. Instead, the character adopts a 'ready to shoot' pose despite being unarmed. I tried deleting all entities... no joy. Then all waypoints... no joy.
I also deleted all .bin, .dat and .dbo files.
I would be most grateful for any help.
Please enjoy my modifications to the stock script if they work for you.
Thanks in adv
ance.
