Say("Hello Maratis")

I could also make this an audio thing so that I could possibly type:

if happy then
    Say(hello)
end

However, in the event that the Say() function is choosing an audio file to play based on an emotion I could type:

Say(hello)

And the character can choose from three different ways to say hello given an feeling:

if happy then 
   hello = getObject("HelloHappy")
elseif sad then
   hello = getObject("HelloSad")
elseif normal then
   hello = getObject("HelloNorm")
end

I think I will be applying fuzzy logic instead of boolean logic to make the Senses system more realistic. For the main 5 senses I will use boolean logic. But to make this more of an AI system, I will use fuzzy logic.

Automatic Navigation -- If an object is seen, the walking character can turn left or turn right. They can jump or duck. I can make invisible primitive planes that, if seen, can make the character turn a certain direction, or perform any other type of action. The same goes for touch. I can't get hearing working yet, and smell requires a particle system (there is one, but it still crashes on me.)

Enemy AI -- if an an enemy sees you, they can attack you.

Trigger Emotions-- The senses can trigger a change in state. Perhaps the character is happy and a happy animation plays, but when it sees a dog, it gets afraid, and the character does a 180' and runs?

I will try to put together a little demo that demonstrates several of these scenarios.

Here is the code for calculating the distance:

function Hear(object)
    earPosition = getPosition(ears)
    heardObjectPosition = getPosition(object)
    
    x2= heardObjectPosition[1]
    x1= earPosition[1]
    y2= heardObjectPosition[2]
    y1= earPosition[2]
    z2= heardObjectPosition[3]
    z1= earPosition[3]
    
    xDiff = x2-x1
    yDiff = y2-y1
    zDiff = z2-z1
    
    radicand =  math.pow(xDiff,2) + math.pow(yDiff,2) + math.pow(zDiff,2)
    distance = math.sqrt(radicand)
    
    if distance > 20 and distance < 30 then
        setText(hear,"I hear something...")
    else
        setText(hear,"I hear nothing")
    end
    
    setText(hear_distance,"Distance:"..distance)
end

Edit: Okay, I put all the text in another scene and used enableCameraLayer() to project it over the main camera. Now I can easily add readouts. I added a readout that displays the name of the object collected (small box).

I am also going to have states that determine what the enemy does.

Is the enemy tired? He will go to sleep (play some animation)

Is he angry? He will pout (some pout animation).

I could set a timer to determine when the enemy will go to sleep. Perhaps that will be a chance for you to sneak past him?

import math
function Hear(object)
    earPosition = getPosition(ears)
    heardObjectPosition = getPosition(object)

    x2= earPosition[1]
    x1= heardObjectPosition[1]
    y2= earPosition[2]
    y1= heardObjectPosition[2]

    xDiff = x2-x1
    yDiff = y2-y1

    radicand =  math.pow(xDiff,2) + math.pow(yDiff,2)
    
    distance = math.sqrt(radicand)
    
    if distance == 0 then
        setText(txt_hearing,"I hear something...")
    else
        setText(txt_hearing,"I hearn nothing")
    end
end

I think that calculus course is coming in handy for checking if things are working. I have to check minimums and maximums to see if it works on either side of 0. I am not printing the distance yet.

I put the "squeeze" on the distance and here is how it checked out:

--At start distance is not equal to 0
--At start distance is greater than 0, which is how it should be. 
-- At start distance is not less than 10
-- At start distance is greater than 10
--I think this might be a scale issue.  I am going to move a box around in the environment to see the scale of the scene. 
-- Turns out, at start, the distance between the ears and the monkey is roughly 130 units. 
-- at start, distance is greater than 20 and less than 30

This doesn't seem right, as it was about 130 units in distance along the X-axis.

I am going to try to use getUnprojectedPoint() this should work better. I will save that for tomorrow. I am going to add some more sound effects to the project for the next upload.

Update: OOPS, that is not the distance forumula for 3d space. I need a "Z" axis in there.
