problem with trying to use attributes for math

[tame cypress]

basically im trying to make a fighting game with multiple abilities. these different abilites would impact the stats of each player depending what one they had. becuase of this i decided to make an attribute for damage get created on a player so i can change it easily but when i try to take away the damage attribute, it gives the error "attempt to perform arithmetic (sub) on number and nil". can you just not do maths on a attribute, and if so how would i go about making a system where i can change the damage when you switch abilities? i can send the code if its required.

send code

alright, give me a sec

i create the attribute in a different script this this line of code :
player:SetAttribute("damage", 10)
but the rest is in a different script located bellow

game.ReplicatedStorage.Remote.activatePower.OnServerEvent:Connect(function(player)

    char = player.Character
    char.Head.Attachment.rightFire.Enabled = true
    char.Head.Attachment2.leftFire.Enabled = true
    char.Head.BrickColor = BrickColor.new("Dark stone grey")
    char.Torso.BrickColor = BrickColor.new("Dark stone grey")
    char["Right Arm"].BrickColor = BrickColor.new("Dark stone grey")
    char["Left Arm"].BrickColor = BrickColor.new("Dark stone grey")
    char["Right Leg"].BrickColor = BrickColor.new("Dark stone grey")
    char["Left Leg"].BrickColor = BrickColor.new("Dark stone grey")
    char.Humanoid.MaxHealth = char.Humanoid.MaxHealth * 2
    char.Humanoid.Health = char.Humanoid.Health * 2
    player:SetAttribute("damage", player:GetAttribute("damage") * 2)
end)

game.ReplicatedStorage.Remote.deactivatePower.OnServerEvent:Connect(function(player)
    char.Head.Attachment.rightFire.Enabled = false
    char.Head.Attachment2.leftFire.Enabled = false
    char.Head.BrickColor = BrickColor.new("Medium stone grey")
    char.Torso.BrickColor = BrickColor.new("Dark stone grey")
    char["Right Arm"].BrickColor = BrickColor.new("Medium stone grey")
    char["Left Arm"].BrickColor = BrickColor.new("Medium stone grey")
    char["Right Leg"].BrickColor = BrickColor.new("Medium stone grey")
    char["Left Leg"].BrickColor = BrickColor.new("Medium stone grey")
    char.Humanoid.MaxHealth = char.Humanoid.MaxHealth / 2
    char.Humanoid.Health = char.Humanoid.Health / 2
    player:SetAttribute("damage", player:GetAttribute("damage") * 2)
end)

everything worked until i added the setAttribute stuff

player:GetAttribute("damage").Value ?

[tame cypress]

oh damn, that would make sense ;-; let me try it rq

nah it didnt work, "attempt to index nil with 'Value'"

[foggy tiger]

hmmm

print(player:GetAttribute("damage")) for me?

[tame cypress]

im already doing that in the other script, i set a variable named damage = player:GetAtrribute("damage") and then printed the variable and then it prints 10 (the base damage i set) so the variable is being made properly

** You are now Level 1! **

[foggy tiger]

HMMM

idk

[tame cypress]

;-; rip

[tame cypress]

do you know another way i could have the same affect of being able to change a individual players damage via script?

[tame cypress]

solved it dw

[foggy tiger]

wut wuz the solution?

[tame cypress]

turns out you were right and even though it printed the damage when the game started, when i actived the ability for some reason damage got set to nil, so now the script checks if the damage = nil, and then sets it equal to 10 if it is

[foggy tiger]

ok

[cunning gulch]

If you created the attribute in a local script and tries to handle it on a server script the server cant see the attribute.

[tame cypress]

oh i see, that makes sense. thanks

[cunning gulch]

Np, little tip next time: on a server script: ```lua
game.Players.PlayerAdded:Connect(function(player)
--do the logic for the player’s starter
end)

[tame cypress]

oh that makes sense, does the same thing as the local script just on a server one

[dense socket]

There's not a single substruction (-) in this script. The error is caused by another script?

If you set an attribute on client, server won't see it

[tame cypress]

yeah, it came from the damage handler script which both had the same problem, so if i figured one out i could fix the other

[dense socket]

Show the script which raises the error

[tame cypress]

oh i already fixed it sorry, thanks anyway

[dense socket]

Ok good luck

[tame cypress]

mb i forgot to add the tag

[cunning gulch]

always configure the player on the server so everybody can see it.
