take damage in sun script

[misty stag]

I'm trying to make a script to make a player slowly take damage when in sunlight, (so if a shadow is above them the player doesn't take damage), but I have little experience in actual scripting and after looking through dev forums have found basically little to nothing.

one of those rare occasions chatgpt can probably write this for you. in short you'd need to do a raytrace between player and sunangle and if it doesn't hit anything then it is in line of sight of the sun and then just use this condition for applying damage

sunangle depends on time of day so, idk you can try to come up with that math yourself, chatgpt can probably give you that specific function

Just don’t use chatgpt

There is no gain in generating shit

[soft summit]

you're welcome to give sun angle formula

[candid frost]

I rather learn than generate shit

[soft summit]

the rest is very simple straight forward raycast(sun_angle_formula()) then the rest is trivial

[candid frost]

Cool, I still prefer learning than generating shit

I’d probably not even be able to fix in the future

hav u learnded how quaternrions work yet?

[candid frost]

Nope

[soft summit]

this is a good principle most of the time, but ai does have its niche uses if you use it properly.

and tbh if it gives bad math then yeah you just write your own, i'm sure google has the formula somewhere

What You'll Need
A Script inside ServerScriptService

Basic Raycasting setup

A loop to check players every few seconds

Script: Sunlight Damage System
Put this Script in ServerScriptService:

lua
Copy
Edit
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local DAMAGE_INTERVAL = 1 -- seconds between damage ticks
local DAMAGE_AMOUNT = 5 -- how much damage per tick
local RAY_HEIGHT = 1000 -- how high the sun is (adjust based on map)

-- Function to check if a player is in sunlight
local function isInSunlight(character)
if not character then return false end

local head = character:FindFirstChild("Head")
if not head then return false end

local origin = head.Position + Vector3.new(0, RAY_HEIGHT, 0)
local direction = Vector3.new(0, -RAY_HEIGHT, 0)

local rayParams = RaycastParams.new()
rayParams.FilterType = Enum.RaycastFilterType.Blacklist
rayParams.FilterDescendantsInstances = {character}

local result = workspace:Raycast(origin, direction, rayParams)

-- If ray hits the character's own head first, it's exposed to sun
if result and result.Instance:IsDescendantOf(character) then
    return true -- In sunlight
else
    return false -- In shadow
end

end

-- Damage loop
while true do
for _, player in pairs(Players:GetPlayers()) do
local character = player.Character
local humanoid = character and character:FindFirstChildOfClass("Humanoid")
if humanoid and humanoid.Health > 0 then
if isInSunlight(character) then
humanoid:TakeDamage(DAMAGE_AMOUNT)
end
end
end
wait(DAMAGE_INTERVAL)
end
