Collision Groups refuse to work

Help and Feedback Scripting Support
#1

I’ve tried everything I could to make this work but it simply wont work.
I’ve tried the collision group editor,
Scripting,
and restarting studio just in case.

But every time, the ball phases through the wall.

Script: (server script service, server script)

local PhysicsService = game:GetService("PhysicsService")

PhysicsService:RegisterCollisionGroup("walls2")
PhysicsService:RegisterCollisionGroup("balls2")

PhysicsService:CollisionGroupSetCollidable("walls2", "balls2", true)

copied & pasted from the documentation but even that wont work

Additional information: it works when i change it to false but not true.
I have tried switching the groups places in the script.
I have tried adding wait()s

#2

Are the ball and the wall CanCollide true?
What happens when you do it manually

#3

The wall is cancollide false and the ball is cancollide true
I need to use collision groups because I want the player to pass through the walls but not the ball.

#4

More information: it works when its changed from

PhysicsService:CollisionGroupSetCollidable("walls2", "balls2", true)

to

PhysicsService:CollisionGroupSetCollidable("walls2", "balls2", false)

(the balls phase through walls but the player doesnt)

bro even roblox is lying to itself :sob:
it says they will collide

#6

ive found another post about this and it turns out
roblox is bugged and setting collision groups to true doesnt work!
so now i have to make it just not collide with player which makes it generally harder. yay. thank you roblox.
