Collission Group Id Help

Hey guys, I’m currently struggling to figure out why the collission group id 5 is not working
I’m trying to make a system similar to this: https://twitter.com/rareheaddress/status/1383618863154176001

I’ve tried using something called Y position check but I can’t figure it out

Anyone know what to do?

Could you provide a lot more details? How exactly are you using collision groups? What are your collision groups, and how are they configured? What is your code that you’ve tried so far?

im using them from the properties tab, I only have the player and the objects in a group, and ive used the code from the roblox collision group dev page

I’m sorry if the information isnt enough, im really stupid so sorry abt that

Im on mobile so i cannot really give you an indept explanetion but from what i see you can use the plr:IsInGroup() function and from there if the plr hit a part for example wait until it no longer hits it and set cancollide to true

That function checks if a player is a member of a roblox group, not a collision group.
