I looking for help, with this, the npc not start to move.

Im trying to create, an NPC wich have multiple walk routes basic logic is 

random pick a route complite the route 

like Route 1 start form zero (0 -> 1 -> 2(or more) -> 1 -> 0)

When the npc return to 0, the script should pic the other route and start again. 

And if there is a message like point 1 here     "route1.addPoint(new RoutePoint(1, 148568, 172328, -980, 5, true, "Puff"));"
The npc should display the chat message.


Currently my problem is the npc not moving, but if I manage it to start moving its randomly move between the route 1 and 2 set of coordinates. Currently for me its  a nightmare.

I hope anyone can help somhow.

Verify if following is supposed to be the way to handle movement

npc.getAI().setIntention(CtrlIntention.AI_INTENTION_MOVE_TO, new Location(point.getX(), point.getY(), point.getZ()));

For me, it's not enough. And if it's the case, whole AI system is probably buggy.

To check the operation of npc movement. You can turn off all movement in the game and move only the npc you want using the move to package. This way you will reduce a lot of unnecessary code and understand where the problem is.

 

 

And all your maps are not thread safe and you are using multithreading

startQuestTimer("move", 5000, npc, null);
