NPC Pathfind Target

Help and Feedback Scripting Support

How could I edit this script so that the NPC only chases a player with a value inside of them set to true?

Screenshot of Value called “survived”

A part of the Script inside NPC Model that chases the player:

function chase()
	while true do
		npchumanoid.WalkSpeed = 20
		npchumanoid.JumpPower = 50
		if not walking and not game.Players:GetPlayerFromCharacter(script.Parent) then
			for i,v in pairs(workspace:GetChildren()) do
				if not v:findFirstChild("Zombie AI") and v:findFirstChildOfClass("Humanoid") and v:findFirstChild("Head") then
					if (v:findFirstChild("Head").Position - npc.Head.Position).magnitude < sight then
						canrandomwalk = false
						local thehumanoid = v:findFirstChildOfClass("Humanoid")
						local pathfinding = false
						local thehead = v:findFirstChild("Head")
						
						while (thehead.Position - npc.Head.Position).magnitude < sight and thehumanoid.Health > 0 and not v:findFirstChild("Zombie AI") do
							npchumanoid.WalkSpeed = 20
							npchumanoid:MoveTo(thehead.Position, thehead)
							local path = game:GetService("PathfindingService"):FindPathAsync(torso.Position, thehead.Position) --find the path from scp's torso to victims head

You could try this code.
Note that this code is not optimized and can be laggy.
I wouldn’t recommend looping through workspace in a while true loop.
The code can be more optimized, i just added the Survive feature.

But that being said, I modified your code a little bit to only make it focus players with the Survived value.

function chase()
    while true do
        npchumanoid.WalkSpeed = 20
        npchumanoid.JumpPower = 50
        if not walking and not game.Players:GetPlayerFromCharacter(script.Parent) then
            for _, player in pairs(game.Players:GetPlayers()) do
                local survivedValue = player:FindFirstChild("Survived")
                if survivedValue and survivedValue.Value == true then
                    for _, v in pairs(workspace:GetChildren()) do
                        if not v:FindFirstChild("Zombie AI") and v:FindFirstChildOfClass("Humanoid") and v:FindFirstChild("Head") then
                            if (v:FindFirstChild("Head").Position - npc.Head.Position).magnitude < sight then
                                canrandomwalk = false
                                local thehumanoid = v:FindFirstChildOfClass("Humanoid")
                                local pathfinding = false

Thanks for the script. There are no error printed but the NPC does not chase me, it just wanders.

#4

Could you add some debug prints maybe?
Like printing the values of canrandomwalk and survived?

#5

The issue is that it thinks that the survived value is false, as it doesnt print the commands inside of the lines after the “if survived == true”.

#6

The chase script is a server script correct?
Is the Survived value being changed by the server or a localscript.
Cause if its changed by a localscript (or changed manually on the client side) the Server won’t pick it up and will indeed not chase the player.
Make sure the survived value is being set to true on the server, maybe test it on the commandbar.

#7

This is the script setting the value to true. This is a ServerScript inside of a part that can is touched by the player.

local plrValue = game.Workspace.PlrValue
local Players = game:GetService("Players")

function onTouched(hit)

	local Character = hit.Parent
	local Player = Players:GetPlayerFromCharacter(Character)
	if not Player then return end
	local humanoid = Character:FindFirstChild("Humanoid")
	if humanoid.Health <= 0 then return end
	local survived = Player:WaitForChild("survived")
	survived.Value = true
	plrValue.Value = hit.Parent.Name
end

script.Parent.Touched:connect(onTouched)
#8

I see the issue, I made a little typo with a character.
Instead of local survivedValue = player:FindFirstChild("Survived")
It should be local survivedValue = player:FindFirstChild("survived")
Lowercase S… Apologies haha, it should work now though. Let me know if it doesn’t! :+1:

Perfect it works, thanks so much. I’m going to make another post soon as when the NPC is chasing a player but the player leaves it just freezes. Do you know any way to fix this before I post? If you want the script, here it is. I know it’s long but you can just look at sections of it if you want.

Do you know what would be a good method for doing this by checking if the player left?

#12

You could maybe add another else statement

I assume the following is all done in the chase function so i’m modifying that with 2 more lines. I just added a if player then statement. Maybe it gives the desired result.

function chase()

Nah bro you’re the best thank you so much, you’ve just solved two problems i’ve been spending a week trying to fix.

#14

Haha you’re welcome. Just send me a message or create another post if you need help with another big issue you’re facing.
Goodluck with your game! :+1:
