Can't find players character

Help and Feedback Scripting Support
#1

  1. What do you want to achieve? Keep it simple and clear!
    I want my script find the players character.

  2. What is the issue? Include screenshots / videos if possible!
    Script:
    local Jenny = game.Workspace.JennyAnimated

local Humanoid = Jenny.Humanoid

local Humanoid2 = Jenny:WaitForChild(“Humanoid”)

local PlayerC = game.Players:FindFirstChildWhichIsA(“Player”).Character or game.Players:FindFirstChildWhichIsA(“PlayerC”).CharacterAdded:Wait()

local PlayerHRP = PlayerC:WaitForChild(“HumanoidRootPart”)

print(PlayerHRP)

local Jenny = script.Parent

local Humanoid = Jenny.Humanoid

local PFS = game:GetService(“PathfindingService’”)

local Path = PFS:CreatePath()

Path:ComputeAsync(Jenny.HumanoidRootPart.Position,game.Workspace.PlayerHRP.Position)

local WP = Path:GetWayPoints()

for i, waypoint in pairs(WP) do

Humanoid2:MoveTo(waypoint.Position)

Humanoid2.MoveToFinished:Wait()

end

while true do

wait()

Humanoid:MoveTo(PlayerHRP.Position)

end

When I play the game, this message pops up in the output: Workspace.JennyAnimated.FollowScript:4: attempt to index nil with ‘Character’

  1. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    I can’t think of any solutions, and I can’t find any solutions on the Developer Hub.

This is a bad way to get the player’s character as it could (in some rare case) reference something else. Instead, you should do something like this:

local Character = Player.Character or Player.CharacterAdded:Wait() -- replace "Player" with your player variable

add this as a server script inside of your jenny

#4

I don’t quite understand the script, so sorry, no.

#5

It is an AI script

filler text filler text

#6

What player variable? I don’t understand.

#7

Is your game a 1 player game?

abcdefghijklmnopqrstuvwxyz

#8

Yes, it’s a 1 player game. Why?

#9

This code is so bad so I am going to rewrite a script for you

#10

put this script in a server script in your jenny (it is an AI, it will make your thing follow the player)

local SearchDistance = 0 -- put here how big you want the radius of your zombie to be
local ZombieDamage = 0 -- put here how much damage you want to zombie to do


local canWander = true -- do you want the zombie to go into an idle mode? (aka: wandering around the place when a player is not in its radius)
local WanderX, WanderZ = 30, 30

I need to understand every detail, and that’s gonna take you years to explain to me. So no.

#12

this is probably never going to get fixed then, plus if you cant understand this basic of a script then you are probably not fit to make a game or script a game

#13

Dude, that stuff is really advanced. If I’m not fit to make a game, then do you want me to stop? How else would I learn to make a game?

#14

You could easily understand what I just sent if you watched a simple tutorial on youtube

#15

If you think this is really advanced then you have no idea what advanced is

#16

That’s what I’m trying to do, but there’s no YouTuber that explains all of it.

#17

I did what you said, but now it says: GetWayPoints is not a valid member of Path “Instance”

#18

It’s GetWaypoints, not GetWayPoints (note the capitalisation).

#19

Oh, thank you. Why didn’t I think of that?

#20

It still gives the message. :confused:
