Post by: salamandra on May 20, 2025, 11:31:29 PM

Server sometimes has an error (NPE)

Code: [Select]

        java.lang.NullPointerException: Cannot read field "_intention" because "this._nextIntention" is null

Maybe need check on null "_intention" in  AbstractAI

Code: [Select]

        synchronized void changeIntention(Intention intention, Object... args)
{
if (_intention != null)
{
_intention = intention;
_intentionArgs = args;
}
}
