Range System System Detect parts inside it

Help and Feedback Scripting Support
#1

I’ve created a range part that follows the player character (The range part is under the HumanoidRootPart position). I’m trying to make it so It’d detect all the parts inside the Range Part.
An example here would be that the range part detects coins

You can use the GetTouchingParts method of the range part’s BasePart object.

#3

I’ve already try that but it doesn’t seem it detects the objects as the Range Part CanCollide is set to false.

#4

Ah! Obviously it won’t if it is set to false as it relies on collision detection to determine which parts are touching the range part.

Since it’s set to false I’d recommend you use the FindPartsInRegion3 method to detect parts within a specified region, which can be the bounding box of the range part.

#5

I’ve never used FindPartsInRegion3. Could you give me an example code as I don’t know how it works?

#6

Yass! Here’s a code I found on the forum. x

-- Define the range part
local rangePart = workspace.RangePart

-- Create a region to search for parts
local region = Region3.new(rangePart.Position - rangePart.Size / 2, rangePart.Position + rangePart.Size / 2)

-- Function to detect parts inside the range part
local function detectParts()
    local parts = workspace:FindPartsInRegion3(region)
    for _, part in pairs(parts) do
        if part:IsDescendantOf(workspace) then
            print(part.Name .. " is inside the range part!")
        end
    end
end

-- Call the detectParts function repeatedly
while true do
    detectParts()
    wait() -- wait a short time before checking again
end

I’ll try that and let you know if it works!

for i,v in pairs(game.Players:GetPlayers()) do
if (v.Character.HumanoidRootPart.Position - coin.Position).Magnitude <= range then
--task
end
end

Something like this?

#9

Thanks for your help! It worked.

I’ve a question though, The range part only detects if the part is in the center. How could I make it so it’d be in any of the range part place?

#11

You can modify the detectParts function to check if the part’s bounding box intersects with the region of the range part.

#12

Can you give a small example code of how it would work?

#13

Yasss of course!

-- Function to detect parts inside the range part
local function detectParts()
    local parts = workspace:GetDescendants()
    for _, part in pairs(parts) do
        if part:IsA("BasePart") and part:IsDescendantOf(workspace) then
            local partRegion = part:GetBoundingBox()
            if region:IntersectsWith(partRegion) then
                print(part.Name .. " is inside the range part!")
            end
        end
    end
end

The BoundingBox part throws me an error in the output:

Here is my code:

local region = Region3.new(glass.Position -  glass.Size /2 , glass.Position + glass.Size/2)
	local parts = workspace:GetDescendants()
	
	for _, part in ipairs(parts) do
		if part.Parent == workspace.Map.GrassLand.Coins then
			
			local partRegion = part:GetBoundingBox()
			
			if region:IntersectsWith(partRegion) then
				part:Destroy()
			end
		end
	end

Can you test my script? Im pretty sure its what you want

#16

My script uses a range part but you use magnitude which won’t work…

#17

Just loop over GetPartsInPart
FindPartsInRegion3 is deprecated

local params = OverlapParams.new()
-- Only include Coins
params.FilterDescendantsInstances = workspace.Map.GrassLand.Coins
params.FilterType = Enum.RaycastFilterType.Include

for _, hit in workspace:GetPartsInPart(rangePart, params) do
    print("Touching a coin:", hit)
end

GetPartsInPart() only works if collision was on.

#19

It would work if CanCollide on.

The only reason it might not work is if you turn off CanQuery.

GetPartsInPart() is different from GetTouchingParts(), GetTouchingParts() is older and shouldn’t be used, GetPartsInPart() is the replacement, which will also get parts with CanCollide false.

Since your part seems to be a sphere, you could also use GetPartsInRadius() which would probably be more performant for you, that way you don’t need any parts.
