Like the eSeries for BG2, tSeries is a set of Player AI scripts for Planescape: Torment. The basis for these scripts comes from Gebhard Blucher's Planescape: Torment Player AI Scripts. I borrowed the scripts that he created and expanded upon them so that they are a bit more comprehensive in terms of spell usage and item usage.

I have used the scripts to complete the game. They were tested with all of the NPCs except Ignus. The scripts appear to function well, given the limits of this version of the scripting language. While I thoroughly enjoyed playing Planescape: Torment, I probably don't plan on another run through. That being the case, unless there are any major bugs in the scripts, this will probably be the final version that I assemble. If you like the scripts and want to improve or expand upon them, the source code is included in the download, so feel free to modify them however you would like. I would just ask that you please credit Gebhard Blucher and I if you place the scripts up for public download.

The scripting language in Planescape: Torment is definitely limited in comparison to the scripting commands available in some of the more recent IE games, but the language still allows for the automation of some tasks, like spell casting, item usage, attacking, and hiding in shadows. The scripts will target the nearest enemy and attack them by whatever means they have available and deem appropriate based on experience point checks of their nearest foe.

The scripts make liberal use of ActionListEmpty(), which means that if you tell them to do something, they will do it rather than following their scripted commands. There is one exception to this rule and that is in the case where a character(s) is low in hitpoints and still under attack. In this case, they will run away from their attacker for a set period of time. If you want the character to stay in combat despite their injuries, you will need to get them healed or turn off the party AI. One other item of note is for Annah or TNO to automatically hide in shadows, they must have a Stealth skill of at least 75%; otherwise, this function will not be activated.
