How would i make this?
This is a pretty important part for my game because there will be a giant explosion and a part will grow so i want it so if that part touches any other parts or models that it will un anchor that part it touched i dont know how to make this ive tried to look it up but i cant find anything.

The following script put inside the expanding part should do:

script.Parent.Touched:Connect(function(part)
    part.Anchored = false
end)

You could also try the following script:

--The following script has a couple of extra things, just to prevent errors.
script.Parent.Touched:Connect(function(part)) --When script.Parent is touched, run the function. "part" would be what touched it
    if part:IsA("BasePart") or part:IsA("UnionOperation") then --Just make sure that it is indeed a part, I don't know what else it could be but better safe than sorry
        part.Anchored = false
    end
end)

Didnt seem to work i dont know why it wouldnt the part is growing via a tween if that helps any its also a sphere

THIS SCRIPT MAY NOT WORK, I don’t work with :GetTouchingParts() ever so yeah.

Hmm, alright

You can try this:

local size = script.Parent.Size
while true do
	if size ~= script.Parent.Size then
		for i, v in pairs(script.Parent:GetTouchingParts()) do
			if v:IsA("BasePart") or v:IsA("UnionOperation") then
				v.Anchored = false
			end 
		end
	end
	size = script.Parent.Size
	wait()
end

This script will instead repeat very fast, and if it detects a change in size it will loop through all parts that are touching the script’s parent, changing them all to unanchored

Does the part is involved with a tween?

It worked a little to well and un anchored itself

#7

Uh what do you mean? Like the growing part?

#8

oops I can change that…

try:

local size = script.Parent.Size
while true do
if size ~= script.Parent.Size then
for i, v in pairs(script.Parent:GetTouchingParts()) do
if v:IsA("BasePart") or v:IsA("UnionOperation") then
if v ~= script.Parent then
v.Anchored = false
end
end
end
end
size = script.Parent.Size
wait()
end

I have no idea what happened to the indents…

It worked! But its ultra laggy i dont think therea way to fix that since its having to deal with so much physics but thanks!

Alright, how about

local size = script.Parent.Size
local activeParts = {}


while true do
	if size ~= script.Parent.Size then
		for i, v in pairs(script.Parent:GetTouchingParts()) do
			if not table.Find(activeParts, v) then
				table.Insert(activeParts, v)
				if v:IsA("BasePart") or v:IsA("UnionOperation") then
					if v ~= script.Parent then
						v.Anchored = false
						--Optionally you can put another wait() here
					end
				end
			end
		end
	end
	size = script.Parent.Size
	wait() --Put a number like 0.1 inside the brackets to reduce lag further
end

Basically I put all objects that have already been modified by the script in a table so it knows not to do it again.

I put a couple of comments in the script as well, where you can add a delay

It says it attempted to call a nill value on if not table.Find(activeParts, v) then

#12

Try lowercase find

So it would be table.find(activeParts, v)

Worked just has to put another lowercase thing on insert then it worked still laggy though but when i do that extra wait it doesnt lag but i have noticed it doesnt un anchor all of the parts if i put the extra wait if i dont put it it un anchors all of them if u put it doesnt
