Disease System and Cures

[ChallengeDev (Carbon)]

Hey everyone! So recently I’ve been working on a disease system that randomly infects you and gives you a certain disease by chance. Now, the problem is, how do I get the tool to cure the one getting the cure?

1. What do you want to achieve? Keep it simple and clear!
   As said before, I need to get the tool to cure whoever is infected.

2. What is the issue? Include screenshots / videos if possible!
   The issue is I do not know how to get it to cure the other person, and remote events haven’t been working very well for this.

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I’ve tried client to server to client, client to server, but neither worked. There wasn’t anything related to this on the Developer Hub that I could find.

Below is the code, I have three scripts, which I will list which is which.

Local Script (In StarterPlayerScripts)

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()

wait(10)
local Cough1Copy = game.ReplicatedStorage.Cough1:Clone()
Cough1Copy.Parent = Character.Head

local Cough2Copy = game.ReplicatedStorage.Cough2:Clone()
Cough2Copy.Parent = Character.Head


game.ReplicatedStorage.Cure1two.OnClientEvent:Connect(function()
	print("RecievedClient")
		wait(4)
		ColdOn = false
	end)


while true do
	
	
	
	local newRandom
	local oldRandom = newRandom
	
	local chosenDisease
	local oldchosenDisease= chosenDisease
	
	
	if TuberOn == true then
		for count = 1, 60 do
			wait(1)
			Character.Humanoid.Health = Character.Humanoid.Health - 1
			Character.Humanoid.WalkSpeed = Character.Humanoid.WalkSpeed - .1
		end
		TuberOn = false
		
	elseif FluOn == true then
		for count = 1, 300 do
			wait(1)
			Character.Humanoid.Health = Character.Humanoid.Health - .1
			Character.Humanoid.WalkSpeed = Character.Humanoid.WalkSpeed - .005
		end
		FluOn = false
		
	elseif ColdOn == true then
		for count = 1, 30 do
		wait(8)
			Cough1Copy:Play()
			Character.Humanoid.WalkSpeed = Character.Humanoid.WalkSpeed - .4
		wait(8)
			Cough2Copy:Play()
		end
		ColdOn = false
	end
	
	
	do repeat
			newRandom =  math.random(20, 30)
			wait()
		until
		newRandom ~= oldRandom
	end
	
	do repeat
			chosenDisease = math.random(0, 100)
			wait()
		until
		chosenDisease ~= oldchosenDisease
	end
	
	
	wait(newRandom)
	print(chosenDisease)
	
	TuberOn = false
	FluOn = false
	ColdOn = false
	
	if chosenDisease >= 90 then
		print("Tuberculosis!")
		TuberOn = true
		
	elseif chosenDisease >= 85 then
		print("Flu!")
		FluOn = true
		
	elseif chosenDisease >= 60 then
		print("Cold!")
		ColdOn = true
		
	elseif chosenDisease >= 0 then
		print("None!")
	end
end

Local Script (In the tool in StarterPack)

local tool = script.Parent
local Debounce = true

tool.Handle.Touched:Connect(function(hit)
	local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
		if Player and Debounce == true then
			Debounce = false
			game.ReplicatedStorage.Cure1:FireServer(hit)
			wait(1)
			Debounce = true
		end
	end)

Server Script (In Server Script Service)

game.ReplicatedStorage.Cure1.OnServerEvent:Connect(function(firing)
	game.ReplicatedStorage.Cure1two:FireClient(firing)
	print("RecievedServer")
end)

[Imaginary_Syntax (AverageSyntax)]

What prints in Output when you execute the script?

[ChallengeDev (Carbon)]

The only thing that prints in output is “RecievedServer” for the server script. The “RecievedClient” never shows up.

[Imaginary_Syntax (AverageSyntax)]

Any errors in the output you are aware of?

[ChallengeDev (Carbon)]

No errors show up. Everything works, just the curing itself doesn’t work, and I can’t figure out how to make it only work on the person the tool touches instead of the one who holds it.

[Imaginary_Syntax (AverageSyntax)]

tool.Handle.Touched:Connect(function(hit)
	local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
		if Player and Debounce == true then
			Debounce = false
			game.ReplicatedStorage.Cure1:FireServer(hit)
			wait(1)
			Debounce = true
		end
	end)

tool.Handle.Touched:Connect(function(hit)
	local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
		if Player and Debounce == true then
			Debounce = false
			game.ReplicatedStorage.Cure1:FireServer(hit)
			wait(1)
			Debounce = true
		end
	end)
end)

Missing “end)”?

[ChallengeDev (Carbon)]

That doesn’t show up anywhere in the output, nothing in the actual script would correspond to that “end)”. There is only one function, one if then statement. Nothing else that gets required “end)”.

[Imaginary_Syntax (AverageSyntax)]

tool.Handle.Touched:Connect(function(part)
		if part.Parent:FindFirstChild("Humanoid") and Debounce == true then
			Debounce = false
			game.ReplicatedStorage.Cure1:FireServer(part.Parent.Name)
			wait(1)
			Debounce = true
		end
	end)

I do not know what your trying to send through “FireServer(hit)”.

use collectionservice to handle the viruses, apply a tag to the character when they have gotten a virus, then have a bindable fire to a virus handler, when the bindable is recieved, check what type of virus it is, and give them the effects desired.

then, when you want to remove the disease, just use CollectionService:RemoveTag(disease), and re-send a bindable to the disease handler, with the disease value being false i recommend you have a boolvalue parameter in the bindable, saying whether to give a disease or not.

i find this tutorial pretty useful, but here is a devhub link also.

I’m trying to send another remote event to the local script in StarterPlayerScripts. Instead of going back to the one who held the tool, I want it to only work on the person who was touched.

(Your updated script doesn’t work either).

[ChallengeDev (Carbon)]

I’ll check it out and post an update after I mess around with it.

[ChallengeDev (Carbon)]

I listened to your advice and added an add tag and remove tag in certain parts of the local script and created a BindableEvent to ReplicatedStorage, but after that I got stuck. I do not know what a virus handler is, nor do I know how to continue with your advice.

I’ll admit I’m sort of beginner level and do not understand most definitions and tricks.

[ekuz0diaa]

quick FYI, bindable events are like remote events that can be received by the same type of script. [ex. server script firing a bindable event, another server script can detect when that bindable event was fired, however remote events cannot do this]

code sample:
client:

--hit is the character that was hit with a needle
virusremote:FireServer("VirusName",hit) -- the true is whether to give disease or not

server:

virusremote.OnServerEvent:Connect(function(originalplr,disease,infectedplr,givedisease)
    virusbindable:Fire(disease,infectedplr)
    collectionservice:AddTag(infectedplr,disease)
end)

virus handler [also server script]

virusbindable.Event:Connect(function(disease,plr)
    if disease == "coronavirus" then
        -- apply effects
    end
    if disease == "remove disease"
       collectionservice:RemoveTag(plr,collectionservice:GetTags(plr)
    end
end)

sorry if i confused you, of course things such as collectionservice and virusremote you will have to define as variables
ex.
local collectionservice = game:GetService("CollectionService")

[ChallengeDev (Carbon)]

For the virus handler, I am a little confused on the code.

 if disease == "coronavirus" then
        -- apply effects
    end

What do you mean by apply effects? Do you mean just disabling the disease, or is this supposed to be another way I can damage and slow down someone?

---

  if disease == "remove disease"
       collectionservice:RemoveTag(plr,collectionservice:GetTags(plr)
    end

Are these two different diseases I am meant to put in the quotations?
Am I meant to keep “remove disease” as is?

Once again, sorry for all the questions. Just want to make sure I don’t mess this up.

[ekuz0diaa]

yeah, where it says apply effects, thats where you do the effects of the disease you want. yes, you keep remove disease the same, when you want to remove a disease you will do virusremote:FireServer("remove disease",hit)

[ChallengeDev (Carbon)]

Jeez, I’m not even sure myself if I am doing this right, I’m learning so much in one night.
Here’s my current code, where do I put the " virusremote:FireServer("remove disease",hit)" and have I put everything else in the right location?

Local Script (In StarterPlayerScripts)

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local CollectionService = game:GetService("CollectionService")

local virusremote = game.ReplicatedStorage.Cure1test

wait(10)
local Cough1Copy = game.ReplicatedStorage.Cough1:Clone()
Cough1Copy.Parent = Character.Head

local Cough2Copy = game.ReplicatedStorage.Cough2:Clone()
Cough2Copy.Parent = Character.Head


game.ReplicatedStorage.Cure1two.OnClientEvent:Connect(function()
	print("RecievedClient")
		wait(4)
		ColdOn = false
	end)

while true do
	
	
	
	local newRandom
	local oldRandom = newRandom
	
	local chosenDisease
	local oldchosenDisease= chosenDisease
	
	
	if TuberOn == true then
		for count = 1, 60 do
			wait(1)
			Character.Humanoid.Health = Character.Humanoid.Health - 1
			Character.Humanoid.WalkSpeed = Character.Humanoid.WalkSpeed - .1
		end
		TuberOn = false
		
	elseif FluOn == true then
		for count = 1, 300 do
			wait(1)
			Character.Humanoid.Health = Character.Humanoid.Health - .1
			Character.Humanoid.WalkSpeed = Character.Humanoid.WalkSpeed - .005
		end
		FluOn = false
		
	elseif ColdOn == true then
		CollectionService:AddTag(Character.Humanoid, "Cold")
		for count = 1, 30 do
		wait(8)
			Cough1Copy:Play()
			Character.Humanoid.WalkSpeed = Character.Humanoid.WalkSpeed - .4
		wait(8)
			Cough2Copy:Play()
		end
		
		ColdOn = false
		CollectionService:RemoveTag(Character.Humanoid, "Cold")
	end
	
	
	do repeat
			newRandom =  math.random(20, 30)
			wait()
		until
		newRandom ~= oldRandom
	end
	
	do repeat
			chosenDisease = math.random(0, 100)
			wait()
		until
		chosenDisease ~= oldchosenDisease
	end
	
	
	wait(newRandom)
	print(chosenDisease)
	
	TuberOn = false
	FluOn = false
	ColdOn = false
	
	if chosenDisease >= 90 then

		TuberOn = true
		
	elseif chosenDisease >= 85 then
		print("Flu!")
		FluOn = true
		
	elseif chosenDisease >= 60 then
		print("Cold!")
		ColdOn = true
		
	elseif chosenDisease >= 0 then
		print("None!")
	end
end

Local Script (In tool in StarterPack)

local tool = script.Parent
local Debounce = true
local virusremote = game.ReplicatedStorage.VirusRemote

tool.Handle.Touched:Connect(function(hit)
	local Player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
		if Player and Debounce == true then
			Debounce = false
			virusremote:FireServer("Cold", hit)
			wait(1)
			Debounce = true
		end
	end)

Server Script (In ServerScriptService)

local virusremote = game.ReplicatedStorage.VirusRemote
local virusbindable = game.ReplicatedStorage.VirusBindable
local collectionservice = game:GetService("CollectionService")

virusremote.OnServerEvent:Connect(function(originalplr,disease,infectedplr,givedisease)
	virusbindable:Fire(disease,infectedplr)
	collectionservice:AddTag(infectedplr,disease)
end)

Server Script (In ServerScriptService)
(Named Handler)

local collectionservice = game:GetService("CollectionService")
local virusbindable = game.ReplicatedStorage.VirusBindable

virusbindable.Event:Connect(function(disease,plr)
	if disease == "Cold" then
		print("GotCold!")
	end
	if disease == "remove disease" then
		collectionservice:RemoveTag(plr,collectionservice:GetTags(plr))
	end
end)

Sorry if this is a bit much honestly. I’m thankful you’re still helping me out.

[astrozzyz (astrozyz)]

So what you can do is place a value that identifies a player with the disease or not, and whenever you use the tool, and I’m assuming clicking on the player, it’ll fire to the server to check everything, such as if they can cure, if they have the tool (exploiters can clone the tool into their backpack), and if the player is sick or not. If nothing appears strange, then you can run the code that cures the player.

[ekuz0diaa]

have you tested your current code? it seems like it would work.

[ChallengeDev (Carbon)]

I haven’t. I guess I probably should, give me a moment.

[ChallengeDev (Carbon)]

It doesn’t work, I just tested it. It didn’t stop the cold from lowering my walkspeed, but it did print “GotCold!”.
