GetPartsInBoundingBox / GetPartsInPart inaccuracies

[metatab1e]

FYI: This may be a bug related to how these functions operate, I’m not sure

I have been attempting to use the functions stated in the topic title to check if a new hallway can be placed in a region in front of a previous one.

I have begun to notice inaccuracies with this system where sometimes for seemingly no reason hallways will still intersect, and I don’t see any errors within my code which would explain why this is happening, so I’m assuming it’s a bug with these functions.

As demonstrated here, rooms intersect.

If you think there is an error somewhere within my code or know a different solution for what I’m trying to do, I would be grateful if you could reply with your solution, I’ll get back to you with how it went when I can.

I have tried GetPartsInPart as well, same results.

I am also certain that I’m sending the correct data to this function, and I believe this since I have also visualized the boxes which I’m using to detect hallways and they intersect eachother.

Pictured here:

Red = intersecting (added manually)
White = visualization parts

Thanks!

Detection function:

local function CheckBounds(NewCF: CFrame, Size: Vector3): boolean
	-- .005 instead of the initial size since otherwise it will detect hallways which don't intersect the box
	for _, Var in ipairs(workspace:GetPartBoundsInBox(NewCF, Size - Vector3.new(0.005, 0.005, 0.005))) do
		if Var:IsA("BasePart") and Var.Name == "Hitbox" then
			return false
		end
	end
	
	return true
end

from what i know Spatial Api also counts objects that intersect to collision, try to make bounding box border a little bit smaller or bigger to see if it would work then

I don’t understand what you mean? I can’t really make sense of what your reply means, no offense.
Making the bounding box border smaller or bigger won’t change anything.

I believe this issue may be solved.

After also giving the spatial query function an OverlapParams such as this:

local BoundsParams = OverlapParams.new()
BoundsParams.BruteForceAllSlow = true

the problem appears to have been fixed.

I’m going to do some testing and if this solves the issue I’ll mark this reply as solution.
