How can I make my custom humans tween toward the person who spawned them?

Hey everyone! At the moment I am writing a class for everything that lives in a game I am making. This class is set up as follows currently:

Object is constructed with a SelfMesh (part in workspace)
Object is given properties (type, occupied, and age)

I have wrote a basic life function called Life:Animate() which at the moment allows the life form to perform five life choices and then they die.

While I am fairly confident the actual life cycle works - the issue seems to be in the possible life choice Life:GoToParent(), in which the life form is supposed to walk toward the person who spawned it. [tl;dr read this paragraph]

(currently the life forms seem to run toward the middle of the baseplate and start to pile up instead of running toward the person who spawned them)

This is the current setup, and my attempt [focus :Animate() and :GoToParent()]:

01local Life = {}
02Life.__index = Life
03 
04function Life.new(initType, trueObject, parent)
05    local thisObject = {}
06    setmetatable(thisObject, Life)
07 
08    thisObject.Type = initType
09    thisObject.SelfMesh = trueObject
10    thisObject.Guardian = parent
11    thisObject.Occupied = false
12    thisObject.Age = 0
13 
14    return thisObject
15end
16 
17function Life:GoToParent()
18    self.Occupied = true
19 
20    local Parent = game:GetService("Players"):FindFirstChild(self.Guardian.Name).Character.HumanoidRootPart
21    local SolvedCFrame = CFrame.new(self.SelfMesh.CFrame.p, Parent.Position)
22    local Direction = (self.SelfMesh.Position).Unit
23 
24    game:GetService("TweenService"):Create(self.SelfMesh, TweenInfo.new(5), {Position = Vector3.new(self.SelfMesh.Position + Direction)}):Play()
25 
26    wait(5)
27 
28    self.Occupied = false
29end
30 
31function Life:Animate(p)
32    self.SelfMesh.CFrame = CFrame.new(p) * CFrame.new(0,1,0)
33 
34    repeat
35        ----------- Life Cycle
36        local LifeChoice = Random.new():NextInteger(1,1)
37 
38        if LifeChoice == 1 then
39            self:GoToParent()
40 
41            repeat wait() until self.Occupied == false
42        end
43 
44        self.Age = self.Age + 1
45        -----------
46    until self.Age == 5
47 
48    self:Death()
49end
50 
51function Life:Death()
52    self.SelfMesh:Destroy()
53    self = nil
54end
55 
56return Life

On this line:

`1`	`game:GetService("TweenService"):Create(self.SelfMesh, TweenInfo.new(5),` `{Position` `=` `Vector3.new(self.SelfMesh.Position + Direction)}):Play()`

You are constructing a new Vector3 with a Vector3 inside of it rather than trying to give it an actual position with numbers. Hence, it is interpreting it as position 0, 0, 0, which is the center of the baseplate. Getting rid of the Vector3.new() should fix this:

`1`	`game:GetService("TweenService"):Create(self.SelfMesh, TweenInfo.new(5),` `{Position` `=` `self.SelfMesh.Position + Direction}):Play()`

This solves your problem, but I see that Direction is a unit vector, which means its size is only 1 stud, so it won't travel too far from self.SelfMesh.Position. Just a heads up.

Additionally, I would like to suggest making use of the .Completed event of Tween rather than explicitly waiting out the length of the tween. Something like this should suffice:

1local tween = game:GetService("TweenService"):Create(self.SelfMesh, TweenInfo.new(5), {Position = self.SelfMesh.Position + Direction})
2tween:Play()
3tween.Completed:Wait()

Ah yes -- I forgot to multiply the unit vector, I had meant to. Anyway; let me give this a try and I'll tell you how it goes. SummerEquinox 643 — 6y

Alright so now they seem to go the opposite direction - which leads me to believe I have made an error in determining the directional vector or something. I'm not the best with this stuff.

You want the SelfMesh to move towards the Guardian, right? Then in the MoveTween definition, you can simply set the Position equal to the position of the Guardian, and that's where it will tween towards. nilVector 812 — 6y

Oh that's true. Man I really suck with this lol. Thank you. SummerEquinox 643 — 6y
