Weapon damage doesn’t work

[quartz marten]

Hellooo! Im making a game and am using a knife tool from the toolbox that’s supposed to damage other players. In an empty game if I use the tool it works and does damage, but in my actual game where I have everything else, it does the sounds and stuff but it doesn’t cause any damage. And I’m not changing anything on it in the actual game and my game isn’t laggy or anything it runs smoothly so idk what the problem is, I’d really appreciate some help! I’m not sure if this is a studio or a script thing because I literally can’t tell what the problem is but I’m posting it here!

Dm me

Whatsoever

[warm island]

local DamageEvent = game:GetService("ReplicatedStorage"):WaitForChild("KnifeDamageEvent")
DamageEvent.OnServerEvent:Connect(function(player, targetHumanoid, damage)
-- Validate to prevent exploits
if typeof(targetHumanoid) == "Instance" and targetHumanoid:IsA("Humanoid") then
targetHumanoid:TakeDamage(damage)
end
end)

But first add a remoteevent

Create a RemoteEvent in ReplicatedStorage (e.g., KnifeDamageEvent).

Then server side damage script Place this in `ServerScriptService

[warm island]

.

And modify ur tknife script : Replace humanoid:TakeDamage(35) in your tool with:

Gotcha — I’ve seen this happen a lot with toolbox melee tools when moving from a blank place into a “real” game.
It’s usually not because the script is broken, but because something in your actual game’s setup prevents damage from being applied.

Here are the most common culprits to check:

1. The tool’s damage script is being blocked by FilteringEnabled / Server-Side checks
   Many toolbox melee tools run on the client and directly change Humanoid.Health.

In an empty baseplate, that works because nothing is stopping it, but in a real game with FilteringEnabled (default now), those changes don’t replicate to the server — so other players won’t take damage.

Fix: Make sure damage is applied on the server (e.g., using a RemoteEvent from the client to tell the server who was hit, then the server sets health).

2. Custom character systems or hitbox scripts
   If your game has a custom character controller, ragdoll system, or modified Humanoid setup, the knife script might be looking for "Humanoid" in a model but not finding it.

Check that the target’s Humanoid name hasn’t been changed, and it’s still in the same structure the knife expects.

3. Collision Groups
   If your knife’s hit detection uses .Touched events, but the knife and the player are in collision groups that don’t collide, .Touched will never fire.

Go to Workspace → Collision Groups and make sure the knife’s parts can collide with the player’s hitboxes.

4. Team / Friendly Fire settings
   Some toolbox weapons check teams and refuse to damage same-team players.

If in your actual game players are on the same team, the script may just skip the damage.

5. LocalScript running in wrong environment
   If it’s a LocalScript inside the tool, in an empty baseplate it runs fine because the player owns the tool.

In your real game, if you moved the tool to a place like ServerStorage or a location where LocalScripts don’t run, it won’t execute.

Stfu

[left stratus]

no you sybau

[warm island]

game:GetService("ReplicatedStorage").KnifeDamageEvent:FireServer(targetHumanoid, 35)

[left stratus]

im helping him

[warm island]

Chat gpt final boss

[left stratus]

yeah

[warm island]

U aint helping him i already did it

[left stratus]

lvl 999

[left stratus]

fair enough

[warm island]

@vocal nebula shoot you shot

[vocal nebula]

You also sent him like the most exploitable piece of code known to mankind, so hopefully he properly sanity checks it

[left stratus]

typeof(targetHumanoid) == "Instance"why this

[warm island]

Why not

[left stratus]

useless

you do TargetHumanoid:IsA("Humanoid") after it

[warm island]

You are right

[left stratus]

also i think kruz is right

its hella exploitable

[warm island]

Here is the corrected validation :

DamageEvent.OnServerEvent:Connect(function(player, targetHumanoid, damage)
-- PROPER validation (order matters for short-circuiting!)
if targetHumanoid and targetHumanoid:IsA("Humanoid") and targetHumanoid.Parent then
local character = targetHumanoid.Parent
-- Optional: Verify target is not the attacker
if character ~= player.Character then
targetHumanoid:TakeDamage(damage)
end
end
end)

What do you think

[warm island]

ig

[left stratus]

exploiter just fires this remote event and passes 999999 damage

[vocal nebula]

yeah

[warm island]

I dont think they will because its not good to do it

[vocal nebula]

they could create a loop kill for every player in the server in like 3 seconds

[left stratus]

wym 😭

[warm island]

Its not cool

[vocal nebula]

oh wait

[vocal nebula]

They can't loopkill everyone

just themselves

[left stratus]

why

[warm island]

How

[vocal nebula]

actually not even that ig

[warm island]

What are you on 🫩

[vocal nebula]

idek

im tired

[warm island]

I am aswell

Lets all use ai

And fck off

😗😗😗😗

[vocal nebula]

real

[warm island]

[vocal nebula]

I may have forgot how clients work for like 2 minutes there 😔

[left stratus]

-- FUCKENG EXPLOIT 
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local KnifeDamageEvent = ReplicatedStorage:WaitForChild("KnifeDamageEvent")

for _,v in game.Players:GetPlayers() do
    if v.Character then
        local hum = v.Character:FindFirstChildOfClass("Humanoid")
        
        KnifeDamageEvent:FireServer(hum, hum.Health)
    end
end

boom hacked

[warm island]

[warm island]

Stop thats not cool

[left stratus]

exploiters don't care 😭

[vocal nebula]

oh shoot

I was correct originally

You're passing in a humanoid variable 😭

[left stratus]

ofc

[warm island]

I dont think dollette will keep up with all these texts

[left stratus]

we won't lel

so to fix it

hmm

wait bruh

[warm island]

Lemme ask an ai real quick

[left stratus]

i didn't even read his msg

[left stratus]

make a hitbox system

[vocal nebula]

He's most likely having a problem where he's doing damage on the client and it's not replicating on the server, which yeah I'd just recommend this

[left stratus]

hm

first thing is

damage variable should be on server

and you shouldn't pass it

nah just make a hitbox system hehe

[vocal nebula]

He should send in a snippet of what he's doing ngl

Might be an entirely other problem

[left stratus]

im just looking at my combat system

[round mortar]

Hello claude

[left stratus]

this is chatgpt.

[round mortar]

😔

[left stratus]

yeah i just have a hitbox system and it fires a remote event
hitboxRE:FireServer("M1Sword", hit, hrp, Combo[plr], ep, pp, false, hitsound)

[round mortar]

Just let ai do all of the code

[left stratus]

and its not exploitable cuz yeah im pro

[left stratus]

fr

[round mortar]

Imagine scripting in 2025

[warm island]

Imagone stealing peoples tag

[vocal nebula]

especially now with chatgpt 5

I sure do love that we're helping this guy with his damage so much

And not talking about taiwan

[warm island]

Never talk about ######

[quartz marten]

HELP WHAT HAPPENED WHILE I WASNT HERE??

Okay I hope that in between all those messages there’s a solution 😇

[round mortar]

Script.parent

[warm island]

None

Loose all hope in your game

[quartz marten]

Oh….! 🥰

[warm island]

Only solution

[vocal nebula]

The solution was that you should prob send in a snippet of the code and make a hitbox system

[quartz marten]

If I put that in my game will it fix my whole world? 😁

[quartz marten]

Ooooo I hadn’t thought about that

That would probably work rlly well actually thx!

[round mortar]

Yes

Add script.parent and it will fix

[vocal nebula]

For better results, define a variable of script.Parent, and then use script.Parent for everything else, anyways

[quartz marten]

Wait actually?

[round mortar]

Yes

[quartz marten]

Do I put it in a script inside the tool?

[vocal nebula]

Trust

yeah

just need a blank script in there with script.Parent

[quartz marten]

I feel like ur all lying to me….😞💔💔💔💔💔

[round mortar]

Bro

Do you want to fix it or no

[vocal nebula]

I'd also just make a hitbox system, just to be safe

[quartz marten]

I’m still gonna try it duhhh

And thx guys I rlly appreciate the help 🥰🥰

Such a sweet community

[quartz marten]

Yeah hopefully what u said works but if it doesn’t I’m probs gonna do that

[round mortar]

No problem

❤️

[vocal nebula]

I can't see any reason why script.Parent wouldn't work...

[quartz marten]

Okay so I just went onto the Knife tool, inserted a script and wrote that

Is that right?

[round mortar]

Yes

[quartz marten]

Okay guys I’ll let u know if it works!!!!!! 😇

It didn’t work at ALL!!! 💔

[vocal nebula]

I could've never expected this outcome

[quartz marten]

Okay i guess I’ll do the hitbox

[round mortar]

Same...

[quartz marten]

Oh my god you little liars

That’s it Im never trusting anyone ever again and it’s all YOUR fault..

[vocal nebula]

If you believed "script.Parent" in a random script would solve anything, that's kinda on you ngl

[grizzled bane]

💀

[quartz marten]

Well tbh with how weird scripting is I thought that maybe random stuff like that would work
