GetRegisteredCollisionGroups not working?

[sussy_bacoo]

script:

while true do
	wait(1)
	for _, group in ipairs(game:GetService("PhysicsService"):GetRegisteredCollisionGroups()) do
		if group.Name ~= "default" then
			game:GetService("PhysicsService"):CollisionGroupSetCollidable(groupName,group,false)
		end
	end
end

this is groupname btw

local groupName = script.Parent.Plr.Value.. "ball"

please help

Hey there!

You would have to register the collisionGroup by doing

game:GetService("PhysicsService"):RegisterCollisionGroup(groupName)

Also the .Name property should be lowercase when using the returned items from GetRegisteredCollisionGroups:

while true do
	task.wait(1)
	for _, group in game:GetService("PhysicsService"):GetRegisteredCollisionGroups() do
		if group.name ~= "Default" then
			game:GetService("PhysicsService"):CollisionGroupSetCollidable(groupName,group.name,false)
		end
	end
end

i already registered groupname, heres the full script:

local groupName = script.Parent.Plr.Value.. "ball"
local existingGroup = game:GetService("PhysicsService"):IsCollisionGroupRegistered(groupName)

if existingGroup then
	
	script.Parent.CollisionGroup = groupName
	else
	
	game:GetService("PhysicsService"):RegisterCollisionGroup(groupName)
	script.Parent.CollisionGroup = groupName
	end

local playergroup = script.Parent.Plr.Value

local playerexist = game:GetService("PhysicsService"):IsCollisionGroupRegistered(playergroup)
if playerexist then
	game:GetService("PhysicsService"):CollisionGroupSetCollidable(playergroup,groupName, false)
end

while true do
	wait(1)
	for _, group in ipairs(game:GetService("PhysicsService"):GetRegisteredCollisionGroups()) do
		if group.name ~= "default" then
			game:GetService("PhysicsService"):CollisionGroupSetCollidable(groupName,tostring(group),false)
		end
	end
end

i think it is the “group” that is the problem

[SupahLuke]

Yes you’re right, you should use group.name instead of just group or tostring(group) inside the CollisionGroupSetCollidable

[sussy_bacoo]

oh yeah i did that and then it started to fall off when i added this:

while true do
	wait(1)
	for _, group in ipairs(game:GetService("PhysicsService"):GetRegisteredCollisionGroups()) do
	
		if group.name ~= "default" and group.name ~= playergroup then
			game:GetService("PhysicsService"):CollisionGroupSetCollidable(groupName,group.name,false)
		end
	end
end
