Hi i'm doing some test, i did a very basic place like a small layrinth with a floor zone covering the place.
i put a sphere but the sphere CAN'T find me, i need the sphere always run after me, like a pac-man idea !
How can i do that, i'm stuck !

Have you set the sphere to be a character and attached some sort of ai script to it?

well this just tells the ball to move in the direction of the player so it will just get stuck on anything in between it and the player... you need to use actual path finding to go around the maze... i.e. use the actual AI logic

Yes and even then, with the AI, it will get stuck sometimes so you have to detect this and then reset the chaser - best in a reverse direction to where the player is looking. Makes for some great sudden catch-ups.

Cheers.

Somebody posted some handy invisible entities with curved shapes that can be placed strategically to minimise the AI getting stuck, worked really well IIRC.

But as I already said you need to use AI commands on characters so they can make use of the built in navigation grid thingy.

i tested it but it's not working because my model is a 3D one object labyrinth the walls are too thick !
i'm not going to use prefabs from GG because the labyrinth is going to be textured at the end with various illustrations on the walls .
my entity can't turn around corners

i tested EVERY entity, with EVERY scrip in GG, nothing works, entities CAN'T find the player in a custom made small labyrinth !
EVEN if i put the view angle 360° and distance to 1000, they see the player but cant walk to it, 99% of time they get STUCK in the walls !

My object is working perfectly, imported in GG with the right collision polygonal.

ALL those problems come from the LUA scripts, they don't work at all !

What the entities absolutely NEED is a detection zone for the walls when that circle enter in collision then the entity need to move away following his actual direction, that way we prevent the entieties to collide & stay stuck inside the walls !

Yep, AI pathfinding isn't going to work inside a single object.

You would have to write your own path finding algorithm.
https://en.wikipedia.org/wiki/Pathfinding

You could try turning physics off on the main model and placing invisible walls for the AI path generation.

Try the invisible wall approach then, if you turn off physics for the main 'maze' entity and mark out the pathways using invisible walls then the AI pathfinding should work.

In the trigger zone script you need to store the position of it such that the entity script can read it, then in the entity script use that as your target position to move to.

Did you try to test the Drone security , because i made a small maze and put a
drone there with his script : . scifi\ai_patrolsecurity.lua
and i made the range 4000 , he then find me with out bumping in to the walls.
Maybe you can some how use his script and mod it to work with your model.

Just a thought.

In one of these threads I suggested using an AI follower object to navigate and follow the player then have a physics object be pushed along to follow the follower object.

Here is a video showing what I meant:

The little ball is under AI control and the large ball is the physics ball, this is just a simple example, more logic is required to control the speed and ensure the physics ball stays in visual contact with the follower entity.
