For those of you attempting to compile KotOR2 scripts that include new constant values or new functions, there appears to be a syntax error in nwscript.nss that will prevent you from compiling!
Near line 5710 you will see:
// RWT-OEI 01/29/04
// 794: Disables or Enables the Orient On Click behavior in creatures. If
// disabled, they will not orient to face the player when clicked on
// for dialogue. The default behavior is TRUE.
void SetOrientOnClick( object = OBJECT_SELF, int nState = TRUE );
The problem lies in this part:
object = OBJECT_SELF
Change it to this:
and then place the modified nwscript.nss file in the same folder as nwnsscomp.exe.
