Thanks! From that I found this:

local rayDirection = game.Lighting:GetSunDirection()

local char = game.Players.LocalPlayer.Character

local RAY_LENGTH = 30

game:GetService(“RunService”):BindToRenderStep(“SunService”,Enum.RenderPriority.Camera.Value + 1,function()
local ray = Ray.new(char.HumanoidRootPart.Position,rayDirection * RAY_LENGTH)
local partFound = workspace:FindPartOnRay(ray,char)
if partFound then
print(“Found something blocking sun:”,partFound)
else
print(“No shadow”)
end
end)

game.Lighting:GetPropertyChangedSignal(“TimeOfDay”):Connect(function()
rayDirection = game.Lighting:GetSunDirection()
end)

@JackscarIitt Are you there? I customized this script to make an AI burn in the sunlight, but it does not work. No errors in output.

local rayDirection = game.Lighting:GetSunDirection()

local char = script.Parent

local RAY_LENGTH = 30

game:GetService(“RunService”):BindToRenderStep(“SunService”,Enum.RenderPriority.Camera.Value + 1,function()

local ray = Ray.new(char.HumanoidRootPart.Position,rayDirection * RAY_LENGTH)

local partFound = workspace:FindPartOnRay(ray,char)

if not partFound then

script.Parent:BreakJoints()

end

end)

game.Lighting:GetPropertyChangedSignal(“TimeOfDay”):Connect(function()

rayDirection = game.Lighting:GetSunDirection()

end)

Could you try this debugging script? Also make sure the script is inside either the workspace or ServerScriptService

local rayDirection = game.Lighting:GetSunDirection()
local char = script.Parent
local RAY_LENGTH = 30

game:GetService("RunService"):BindToRenderStep("SunService",Enum.RenderPriority.Camera.Value + 1,function()
    print("Running")
    local ray = Ray.new(char.HumanoidRootPart.Position,rayDirection * RAY_LENGTH)
    local partFound = workspace:FindPartOnRay(ray,char)
    if not partFound then
        print("Found part")
        char:BreakJoints()
    else
        print("Not found part")
    end
end)

All right I will try this in a bit and tell you how it goes.

Edit: Oddly, it is now working (aside from in it’s first life before any respawns, which I can easily fix by killing it once). Thanks!

@JackscarIitt I’m sorry but once again, I need your help. The script only works sometimes.

#8

Can you check what the Output prints each time you head somewhere?

Yes, I did. One the times that the script does not work, it prints nothing. On the times the script does work, however, it prints accordingly and properly.

@JackscarIitt (sorry for the ping but you weren’t responding. Do you mind pings?)

#11

Pinging me won’t really do anything unless if I’m actually available at this point of time

So apparently I just realized that you can only use BindToRenderStep on the Client, and not the Server whoops

If you want a NPC/AI, use Heartbeat on the Server I believe:

local rayDirection = game.Lighting:GetSunDirection()
local char = script.Parent
local RAY_LENGTH = 30

print(rayDirection)
game:GetService("RunService").Heartbeat:Connect(function()
	print("Running")
	local ray = Ray.new(char.HumanoidRootPart.Position,rayDirection * RAY_LENGTH)
	local partFound = workspace:FindPartOnRay(ray,char)
	if not partFound then
		print("Found part")
		char:BreakJoints()
	else
		print("Not found part")
	end
end)

Thank you. Heartbeat works! :slight_smile:
