How can I make a part not have the cancolloid, but still not go inside another part?

  1. What do you want to achieve? So basically my water part has CanColloide false, but i don’t want it goes inside another part with CanColloide true, but the player can still go inside the part without the cancolloide. How do i do it?

I tried to make a script using collision groups, but it isn’t working (it’s a serverscript)

local PhysicsService = game:GetService("PhysicsService")

local drum = "Drum"
local water = "Water"

PhysicsService:RegisterCollisionGroup(water)
PhysicsService:RegisterCollisionGroup(drum)

local waterPart = workspace.Water
waterPart.CollisionGroup = water

local drumPart = workspace.WashingMashineClassic["Constarin Cestello"].Union
drumPart.CollisionGroup = drum

PhysicsService:CollisionGroupSetCollidable(water, drum, false)
#2

Assign a collision group to player on character added event, make that group uncollidable with the water’s group, and collidable with the drum group.

local PhysicsService = game:GetService("PhysicsService")

local water = "Water"
local chara = "Char"

PhysicsService:RegisterCollisionGroup(chara)

game.Players.PlayerAdded:Connect(function(plr)
	
	plr.CharacterAdded:Connect(function(char)
		
		plr.Team = game.Teams.Lobby
		
		for i,part in pairs(char:GetChildren()) do
			if part:IsA("BasePart") then
				
				part.CollisionGroup = chara
			end
		end
		
		
	end)
	
end)


PhysicsService:RegisterCollisionGroup(water)

local waterPart = workspace.Water
waterPart.CollisionGroup = water


PhysicsService:CollisionGroupSetCollidable(chara, water, false)

Ty for the answer
I treid to make this script, but it doesn’t work. What’s the error?

as you can see, my character cannot enter into the part

Try using GetDescendants when the character gets added instead.

It is not woring anyway

local PhysicsService = game:GetService("PhysicsService")

local water = "Water"
local chara = "Char"

PhysicsService:RegisterCollisionGroup(chara)

game.Players.PlayerAdded:Connect(function(plr)
	
	plr.CharacterAdded:Connect(function(char)
		
		plr.Team = game.Teams.Lobby
		
		for i,part in pairs(char:GetDescendants()) do
			if part:IsA("BasePart") then
				
				part.CollisionGroup = chara
			end
		end
		
		
	end)
	
end)


PhysicsService:RegisterCollisionGroup(water)

local waterPart = workspace.Water
waterPart.CollisionGroup = water


PhysicsService:CollisionGroupSetCollidable(chara, water, false)

Check if the parts are actually getting the collision group while playtesting, from properties I mean, and make sure it’s not giving you any error. It may be because right after character is added character parts aren’t completely loaded. Try using CharacterAppearanceLoaded instead of CharacterAdded.
