So how is this possible

---Code:

print(type(self.Dna.Genes[1]), self.Dna.Genes[1])
self.MaxSpeed = MathLib:Map(self.Dna.Genes[1], 0, 1, 15, 0)

function MathLib.Map(Value, Low1, Low2, High1, High2)
return High1 + (High2 - High1) * (Value - Low1) / (Low2 - Value)
end

---Output:

number 1
The error is saying value is a table value when it's obviously not

self.Dna.Genes[1] = math.random(0, 1)

The error still occurs saying its a table wether I give it a string, a number, or anything else

Do you understand why this doesn't make any sense? Is this a common problem?

Here is the entire program if for some reason you need it, I'm running on codea and iPad app.

-- Ecosystem

function setup()
Creatures = {}
CreatureAmount = 20

for Index = 1, CreatureAmount do
Creatures[Index] = Creature()
end
end

function draw()
background(255, 255, 255, 255)

for _, Creature in next, Creatures do
Creature.Update()
Creature.Display()
end
end

Creature = class()

function Creature:init()
self.Color = color(math.random(1, 255), math.random(1, 255), math.random(1, 255))
self.Offset = vec2(math.random(-10000, 10000), math.random(-10000, 10000))
self.Position = vec2(math.random(1, WIDTH), math.random(1, HEIGHT))
self.Dna = Dna()

print(type(self.Dna.Genes[1]), self.Dna.Genes[1])
self.MaxSpeed = MathLib:Map(self.Dna.Genes[1], 0, 1, 15, 0)
self.Radius = math.random(15, 100)
self.Health = 200

function self.Update()
local VelocityX = MathLib.Map(noise(self.Offset.x), 0, 1, -self.MaxSpeed, self.MaxSpeed)
local VelocityY = MathLib.Map(noise(self.Offset.y), 0, 1, -self.MaxSpeed, self.MaxSpeed)
local Velocity = vec2(VelocityX, VelocityY)

self.Offset = self.Offset - vec2(0.01, 0.01)
self.Position = self.Position + Velocity
self.Health = self.Health - 1
end

function self.Display()
stroke(self.Color)
fill(self.Color)

ellipse(self.Position.x, self.Position.y, self.Radius)
end

function self.Dead()
if self.Health <= 0 then
return true
else
return false
end
end

function self.Eat()
local Foods = Foods:Fetch()

for _, Food in next, Foods do
if self.Position:dist(Food) < self.Radius then
self.Health = self.Health + 100
end
end
end
end

Dna = class()

function Dna:init()
self.Genes = {math.random(0, 1)}
end

MathLib = class()

function MathLib.Map(Value, Low1, Low2, High1, High2)
return High1 + (High2 - High1) * (Value - Low1) / (Low2 - Value)
end

that '[1]' why is that there, what is its necessity being there if you are using math.random(); because otherwise of course it would error, because you're trying to print the first value of something that isn't a table

I don't think you understand, even if I give that parameter a nil value it still says it's a table

it's because you're using colon syntax for whatever reason when calling MathLib.Map, so MathLib is automatically passed as the first parameter, "Value"

e.g

local MathLibrary = {}

function MathLibrary.Map(example)
print(example)
end

MathLibrary.Map(5)
MathLibrary:Map()

OUTPUTS:
5
table: 0x1e8c4730
