GetPartsInPart not showing objects in a part

[JackTheVoid (MessiahOfPebbles)]

1. print a list of items with “propulsable” (which I am now aware is not a word) collisiongroup inside another object

2. item with the correct collision group isn’t being detected

3. checking for syntax errors and changing default conditions in overlap params to see if the object doesn’t align with some of the values (it’s possible I overlooked a value, but I don’t think it’s likely)

here’s my code:

local params = OverlapParams.new()
params.FilterType = Enum.RaycastFilterType.Include
params.CollisionGroup = "propulsable"

script.Parent.Activated:Connect(function()
	local objects = workspace:GetPartsInPart(script.Parent.Zone_Of_Propulsion,params)--params
	print(objects)
end)

screenshots show my explorer; shootable’s properties (that is the wall on the right in another screenshot); picture of client’s game wherein there are two walls - one of which should show in the outputted but isn’t.

Sorry, I forgot to include the screenshots.

@JackTheVoid

params.FilterType = Enum.RaycastFilterType.Include

You want this to be Exclude, not Include. Include means parts that are both found inside the OverlapParams.FilterDescendantsInstances (in your case an empty list) and can collide with propulsable.

NVM. That was absolutely right. I couldn’t get it to work with your solution before because I didn’t know how collision groups worked (I assumed wrongly that they were just an attribute). Thank you so much, I lost sleep over this issue!
