This may help, that instead of you having to reinvent the wheel ( where you could concentrate on other things in your game instead) you could bring it into Maratis, though I have no idea how that would be done , my self not  being a master programmer , but anyway its here:

I clearly have no idea if its what you're after but it might save you valuable time if it is, and help others as well looking for similar things.

I like the seeing, a big cone. Haha

I'm right now making an AI-system, it's the most fun of it all. Right now I'm trying to figure out how to make objects look at certain objects using the Z-angle. Trying to do the math. Gonna keep it up. So thanks for the answer.

I have made a working ammo-system now and I'm about to script an AI system. Is there any good ways to go about this?
I will also script some kind of a hitbox, I'm not sure how to do this as well.

/P

Hey Par! I have been waiting to share some ideas about the way my idea of a game engine would work, and I have thought of an AI system (at least how it would work).

I think the best AI system is one that simulates our own intelligence in real life. All humans have 5 senses. Sight, Hearing, Smell, Taste, and Touch.

If you build a SENSES SYSTEM, then you can give whatever object you want a sense of Artificial Intelligence. You basically create some SENSE OBJECTS. I will give a brief demo:

TOUCH:
Touch is basically simulated using COLLISION detection. Giving an entity the ability to sense when it is colliding with something is simulating the sense of TOUCH.

SIGHT:
Sight also uses collision detection. Attach a CONE to the front of an object. This will be the FIELD OF VIEW. Anything that collides with the cone is SEEN! (The cone must not have physics. In other words, it shouldn't react to the collision). The width of the cone simulates how wide the object can SEE. The transparency of the cone would simulate how WELL the object can see (more transparent means worse sight). The LENGTH of the cone would simulate near or farsightedness.

HEARING:
Hearing uses a PROXIMITY system. The closer you get to an object that makes sound, the HIGHER THE VOLUME and PITCH of an object gets (Doppler effect). The Hearing() function basically turns up the volume of an object the closer you get. You could also use a SPHERE as your FIELD OF HEARING and make a proximity system based on how far an object is from the center of the sphere.

SMELL:
Smell uses a PARTICLE SYSTEM. Odors act more like particles. The smell system is just a sphere that can detect when a particle has entered it. If a particle has entered the sphere that particle system is SMELLED!

TASTE:
Taste  is just a collision detection also. Works like the TOUCH system. But the taste object is just located near a mouth.

All these senses are FUNCTIONS:

Touch()
See()
Hear()
Smell()
Taste()

And all the things they can sense are entities/objects:

box
man
radio
particleSystemGas
meat

And when these senses get triggered, things happen:

Fall()
Wave()
Dance()
Frown()
RubTummy()

Take Care!

text = getObject("text")
val = 0

function increment(i)
    return i + 1
end

function onSceneUpdate()
    setText(text, val)
    if isKeyPressed("W") then
        val = increment(val) -- Calling function increment
    end
end

It's named increment only for logic sake.
Function arguments are only local to the function so it's generic like a rule or a mathematical function.
When you call the function you pass it any variable in argument.

So val is automatically switched to i in the code?

I copy pasted this code but it doesn't work, I press W but it doesn't change to 1.

So I figure I could write this code:

text = getObject("text")
i = 0

function increment(i)
return i + 1
end

function onSceneUpdate()
setText(text, i)
if IsKeyPressed("W") then increment() -- Calling function increment
end

I was wrong, it don't work. What am I doing wrong? :)

and grabbing some of the examples on the main page of Maratis3d.com and analyzing the code. hope this helps.
