How to check if a part touches something in a model?

Hi, I’m scripting and I realized something. I was making a script that destroys a part if it’s falling down and touching a part that’s in a model called “Map”. But I don’t know how to make a script that detects if the part is touching something in the model.

script:

while true do task.wait()
	if script.Parent.AssemblyLinearVelocity.Y < -5 and script.Parent.??? then
		script.Parent:Destroy()
	end
end

can someone help me with the script?

Don’t use a while loop for checking they are messy and very inefficient.

There are events for when parts touch things (part.Touched) that also pass what touched(hit). You can check if hit is something in the model using an if statement.

part.Touched:Connect(function(hit)
   if hit.Parent == Model then
      -- code
   end
end)

It appears you’ve never used events. Here’s a good beginner video.

You’ll need to use an event, as already aforementioned. Here is the right way to check if it a part in the model has been touched by your part:

script.Parent.Touched:Connect(function(hit) -- assuming that the parent is the part
    if script.Parent.AssemblyLinearVelocity.Y < -5 and hit:IsADescendantOf(Model) then
        script.Parent:Destroy()
    end
end)

Change 'Model' on Line 2 so it references the model called ‘Map’.

I also thought I’d mention that event is something that is fired when something happens, e.g. the Touched event fires when the mentioned part collides with another object, and then the function attached to it runs automatically when touched. The argument in the function, which is ‘hit’ in this scenario, is the variable containing the part that it collided with.

your script works, but when I put it

and script.Parent.AssemblyLinearVelocity.Y < -5

does not work.
