How Could I Check If A Collision Group On PhysicsService Already Exists?
So I Recently Stumbled Upon A Error In My Game It Says:
****Cannot Create Collision Group One Already Exists
So I Was Wondering How Could I Check To See If it Already Exists To Prevent Errors?
Here Is My Code:
1 | physicsService = game:GetService'PhysicsService' |
2 | for i = 1,3 do |
3 | if physicsService:GetCollisionGroupName("Group"..i) then |
4 | print("Collision Groups Exist!") |
5 | else |
6 | physicsService:CreateCollisionGroup("Group"..i) |
7 | end |
8 | end |
9 | physicsService:CollisionGroupSetCollidable("Group1", "Group2", false) |
Please Help As I Have Not Seen This Error Before.

I found a devforum post related to your error, you can try this
01 | local PhysicsService = game:GetService("PhysicsService") |
02 |
03 | local function CreateCollisionGroup(collisionGroupName) |
04 | local createdGroups = PhysicsService:GetCollisionGroups() |
05 | local collisionGroupExists = {} do |
06 | for _, createdGroup in pairs(createdGroups) do |
07 | collisionGroupExists[createdGroup] = true |
08 | end |
09 | end |
10 |
11 | if not collisionGroupExists[collisionGroupName] then |
12 | PhysicsService:CreateCollisionGroup(collisionGroupName) |
13 | end |
14 | end |
15 |
16 | CreateCollisionGroup("Group1") |
17 | CreateCollisionGroup("Group2") |
18 | PhysicsService:CollisionGroupSetCollidable("Group1", "Group2", false) |
I don't have much experience with PhysicsService, so this may not work Post: https://devforum.roblox.com/t/script-erroring-that-a-collision-group-already-exists-when-it-doesnt/322318
