		end

end)

PhysicsService:CollisionGroupSetCollidable(nontaggedplayers, Zones, false)

the prints work but when im not tagged i still cant enter the zone

#2

You’ll have to change the collision groups of all parts of the player’s character to nontaggedplayers instead of just the UpperTorso.

#3

what about just da humanoidrootpart will that work to

#4

Probably not, unless all other parts of the character have CanCollide off. Here’s an article that accomplishes something similar—take a look at Code Sample 4.

Edit: Forgot to link the article, sorry. :man_facepalming:

#5

Try this code, let me know if it works.

local ServerStorage = game:GetService("ServerStorage")
local PhysicsService = game:GetService("PhysicsService")
local CombatTaggedFolder = ServerStorage.CombatTaggedPeople
local Zone = script.Parent
local Zones = "Zones"
local nontaggedplayers = "taggedplayers"

PhysicsService:CreateCollisionGroup(Zones)
PhysicsService:CreateCollisionGroup(nontaggedplayers)

PhysicsService:SetPartCollisionGroup(Zone, Zones)

local function setCollisionGroup(character, groupName)
	for _, child in ipairs(character:GetChildren()) do
		if child:IsA("BasePart") then
			PhysicsService:SetPartCollisionGroup(child, groupName)
		end
	end
	character.DescendantAdded:Connect(function(descendant)
		if descendant:IsA("BasePart") then
			PhysicsService:SetPartCollisionGroup(descendant, groupName)
		end
	end)
end

Zone.Touched:Connect(function(touched)
	if touched.Parent:FindFirstChild("Humanoid") then	
		if not CombatTaggedFolder:FindFirstChild(touched.Parent.Name) then
			print("player isnt tagged")
			setCollisionGroup(touched.Parent, nontaggedplayers)
		else
			print("player is tagged")
		end
	end
end)

PhysicsService:CreateCollisionGroup(Zones)

			for i,v in pairs(touched.Parent:GetChildren()) do
				if v:IsA("Part") or v:IsA("MeshPart") then
					PhysicsService:SetPartCollisionGroup(v, nontaggedplayers)
				end
			end
		end
	end
end)

Zone.TouchEnded:Connect(function(touched)
	if touched.Parent:FindFirstChild("Humanoid") then	
		for i,v in pairs(touched.Parent:GetChildren()) do
			if v:IsA("Part") or v:IsA("MeshPart") then

			end
		end
	end
end)

thanks for da help my safezones work now :smiley:
