o yeah i forgot. its for kotor 2.
There are some scriptsi n the game you can use in the "Script #" boxes in tk102's DLG Editor to accomplish these tasks. They generally require you to specify a parameter in one of the boxes to the right as well:
Task Script Dialog script parameters
----------------- ---------------- ----------------------------
Full darkside a_givedark P1: DS points to give (100 is max)
Full Lightside a_givelight P1: LS points to give (100 is max)
give a lightsaber a_give_item String Param: Name of UTI file to give item from
full influence a_influence_inc P1: Party member number to adjust (0-11)
The source code for all those can be found in scripts.bif with KotorTool if you want to see how they work more exactly.
As for adding a party member, depends on if you want to add one of the existing party members, or a new one created by a mod.
EDIT: Didn't you ask pretty much the same thing in this thread (
