How would I do this?

Help and Feedback Scripting Support
#1

so i have a script:

local function registerCollisionGroup(player)
	local collisionGroupName = player.Name
	local collisionGroup = game:GetService("PhysicsService"):RegisterCollisionGroup(collisionGroupName)
	return collisionGroup
end
local PhysicsService = game:GetService("PhysicsService")
game.Players.PlayerAdded:Connect(function(player)

	player.CharacterAdded:Connect(function(char)
	local collisionGroup = registerCollisionGroup(player)
		
	PhysicsService:CollisionGroupSetCollidable(tostring(player.Name),"NoPlayer", false)
	for _,part in pairs(char:GetDescendants()) do
		if part:IsA("BasePart") then
			part.CollisionGroup = tostring(player.Name)
		end
		end
		
	end)
	
	
	
end)


game.Players.PlayerRemoving:Connect(function(player)

	PhysicsService:UnregisterCollisionGroup(player.Name)
end)

this gives the player a custom collision group. how would i disable collision with other players? i tried looping:

local function registerCollisionGroup(player)
	local collisionGroupName = player.Name
	local collisionGroup = game:GetService("PhysicsService"):RegisterCollisionGroup(collisionGroupName)
	return collisionGroup
end
local PhysicsService = game:GetService("PhysicsService")
game.Players.PlayerAdded:Connect(function(player)

	player.CharacterAdded:Connect(function(char)
	local collisionGroup = registerCollisionGroup(player)
		
	PhysicsService:CollisionGroupSetCollidable(tostring(player.Name),"NoPlayer", false)
	for _,part in pairs(char:GetDescendants()) do
		if part:IsA("BasePart") then
			part.CollisionGroup = tostring(player.Name)
		end
		end
		while true do

			for _, group in ipairs(game:GetService("PhysicsService"):GetRegisteredCollisionGroups()) do

				if group.name ~= "Default" and group.name ~= player.Name.. "ball" then
					game:GetService("PhysicsService"):CollisionGroupSetCollidable(collisionGroup,group.name,false)
				end
			end
			wait(1)
		end
	end)
	
	
	
end)


game.Players.PlayerRemoving:Connect(function(player)

	PhysicsService:UnregisterCollisionGroup(player.Name)
end)

which didnt’s work, help would be greatly apperciated

From what i’ve tested, RegisterCollisionGroup doesn’t return the collision group it creates, so you should access it by the player’s name instead.

local function registerCollisionGroup(player)
	local collisionGroupName = player.Name
	game:GetService("PhysicsService"):RegisterCollisionGroup(collisionGroupName)
end
local PhysicsService = game:GetService("PhysicsService")
game.Players.PlayerAdded:Connect(function(player)

	player.CharacterAdded:Connect(function(char)
		registerCollisionGroup(player)

		PhysicsService:CollisionGroupSetCollidable(tostring(player.Name),"NoPlayer", false)
		for _,part in pairs(char:GetDescendants()) do
			if part:IsA("BasePart") then
				part.CollisionGroup = tostring(player.Name)
			end
		end
		while true do

			for _, group in ipairs(game:GetService("PhysicsService"):GetRegisteredCollisionGroups()) do

				if group.name ~= "Default" and group.name ~= player.Name.. "ball" then
					game:GetService("PhysicsService"):CollisionGroupSetCollidable(player.Name,group.name,false)
				end
			end
			wait(1)
		end
	end)



end)


game.Players.PlayerRemoving:Connect(function(player)
	PhysicsService:UnregisterCollisionGroup(player.Name)
end)
