Decrese IQ of monsters

[Lyky]

Hi,
So my players have been sending complains for dragons on my server having over 200 IQ; Its running on [TFS 1.2];

I was wondering if its possible - through lua - make monsters having a chance turn towards player 20% per 2sec turn.

As it stands now, all of my monsters automatically from a get-go turn to player position, and when running away they move in a way so that player is going to be hit by a wave attack, and dodge their attacks.

The issue has been described here:

Monster AI Revamp [$100] · Issue #922 · otland/forgottenserver · GitHub [2014 couple years back]
Turning/Facing - if a creature changes directions while while moving there is no delay before or after the turn, they turn and take their next step in a fluid motion. During dancestep if the creature turns away from the target when it moves, it will adjust the direction to face the target again during it's next attack interval (turn and attack in fluid motion)

later stated it has been implemented; thus how to control that turning/facing direction switch chance?


@edit
After thinking a little bit about it; it should be scriptable in creaturescripts; but i have no idea how to start - can anyone point me to example that modifies how certain creatures behave.

Could you give small example how the script should be structured, to affect creature and how to call Turn direction behavior of it?

Sorry no, that requires too much time to exaplain.
And its not like I can copy paste my monsterAI what would make sense for you, its 500+ lines long.

Why not provide a simple example then?

btw. here's another example of how dragons didn't turn look to player direction right away.
1min 30 mark

it may be affected by spell cast / melee attack. I'll test it out on the server by reducing melee attack speed.

TESTED - Its not affected by spell cast or attack. It does it in immediate mode turn to player direction after each move.

I am lost lol, i have no idea what you are trying to accomplish.

If you watch that video, you see that the dragon doesn't turn instantly to the player. When going down it takes time until he turns to the side of the player.

Sorry no, that requires too much time to explain.

Simplifying a small feature in complex sequence requires quite some time to explain because rewriting monster behavior will mess up a lot of other things which you need to take into consideration.

 

[e.e]

Melee monsters on real (at least in 7.7) change direction towards its target no matter what right before or after the monster is about to melee (every 2 seconds), and this mechanic is what OP seems to want to implement in his OT (OT monsters by default change their direction immediately after every move).
OT monsters are in general much more robotic in their behavior, they behave more like magnetic robots than creatures.

Hi,

Additional questions,


creature.h [line: 80-82]

#define EVENT_CREATURECOUNT 10
#define EVENT_CREATURE_THINK_INTERVAL 1000
#define EVENT_CHECK_CREATURE_INTERVAL (EVENT_CREATURE_THINK_INTERVAL / EVENT_CREATURECOUNT)

Could someone explain what is FrozenPathingConditionCall - purpose?

class FrozenPathingConditionCall
{
   public:
       explicit FrozenPathingConditionCall(Position targetPos) : targetPos(targetPos) {}

       bool operator()(const Position& startPos, const Position& testPos,
                       const FindPathParams& fpp, int32_t& bestMatchDist) const;

       bool isInRange(const Position& startPos, const Position& testPos,
                      const FindPathParams& fpp) const;

   protected:
       Position targetPos;
};

also has anyone tested windows debugger on the code with visual studio? Does it work well when you put breaks in the code? Also if anyone could point me to code where creature (non-player) updates direction?



//i.e. creature.cpp Direction var is not defined.

Since you doing source edits. Check into follow creature related functions.
Because if creature does not follow player it does not turn to them either.
However if monster doesn't have follow target and target list is updated, source gives the monster a target to follow. Hence the reason its so annoying to make monster behavior only in Lua
