How to use Region3 on a part to detect when touched by another part?

Help and Feedback Scripting Support
#1

I am new to Region3 and I watched some videos of it and got some reference but I do not know how to achieve what I want with it.
I am currently trying to make a model unanchor all its parts in it when it touches a specific part named “InnerExplosion”

local part = script.Parent

local region = Region3.new(part.Position - part.Size/2, part.Position + part.Size/2)

while true do
local parts = workspace:FindPartsInRegion3(region, part)

for i, part in pairs(parts) do
	local player = game.Players:GetPlayerFromCharacter(part.Parent)
	if player then 
		print(player.Name)
	end
end

end

You shouldn’t use Region3 since it’s deprecated. Instead, you can use GetPartBoundsInBox which might be easier to implement and isn’t deprecated.

GetPartBoundsInBox returns an array of parts that overlap with the bound you specified, you simply check every frame if this box is overlapping, you can do it this way:

local RunService = game:GetService("RunService")
local Part = (PART)

RunService.Heartbeat:Connect(function()
    local overlapping = workspace:GetPartBoundsInBox(part.CFrame, part.Size*Vector3.new(1.25,1.25,1.25))

    for _, v in pairs(overlapping) do
        if v.Name == "InnerExplosion" then -- FOUND!!

            for _, val in pairs(v.Parent:GetDescendants()) do
                if val:IsA("BasePart") then -- ok it's a part
                    val.Anchored = false
                end
            end
        end
    end
end)

btw remember to disconnect the Heartbeat event when you’re done checking, or else it might start lagging a little bit.

Alright it works but it also unanchors other parts and basicly the whole map

Oh, the script I gave you unanchors every single part inside the part’s parent. In the second for loop you can replace v.Parent: GetDescendants() by (MODEL): GetDescendants()

If I put this script into a building and clone the building alot of times and place them on a map.
Would it cause alot of lag?

Depends on how fast your device is. You might wanna look into Network ownership in order to avoid lag as the server will be the one that calculates the physics.
