How can a script know if two parts are touching?

This is the current script. It works in a sense but doesn't do what I want it to do.

01local Target = script.Parent.Spreadable
02local touching = Target:GetTouchingParts()
03 
04function makefire(parent)
05    local fire = Instance.new("Fire")
06    fire.Parent = parent
07end
08 
09for _, part in next, touching do
10    wait(1)
11    makefire(part)
12end

I'm trying to make a series of parts and I want the fire to spread to the part that it's touching if it has the same name, "spreadable". They are all inside a model but this only spreads the fire if the parts are inside of each other. I'm trying to make this work if the parts are touching. I tried the touched() function but that doesn't work either unless there is a collision. How can I fix this? Thanks.

What do you mean touching but the touch event doesn't work? GoldenPhysics 474 — 9y

Since fire only has to be near something to make it light up, you could try using a for loop and Magnitude. TheDeadlyPanther 2460 — 9y

I would use an Anonymous Function to do this.

Alright so we start by using an anonymous function and declaring what fire is.

1script.Parent.Touched:connect(function(hit)
2local f = script.Parent:findFirstChild("Fire")
3 
4end)

Now, we use the .Touched event in order to signal that IF the object the script is inside is either touched or is touching another object it will do something. we also declare that f is fire because, we do not need to create the fire within the script it could later on cause complications.

Now lets move on to what happens WHEN this object is touched or touches something.

01script.Parent.Touched:connect(function(hit)
02local f = script.Parent:findFirstChild("Fire")
03 
04if hit.Parent:IsA("Part") then
05x = f:Clone()
06if hit.Parent.Name == string.lower("spreadable") then
07 
08end
09end
10end
11end)

Now you might ask Why are we using an :IsA in the script, well this just checks if the object it touched is a Part, we also made a new variable called x that is now a Clone of Fire, we also checked to see if the thing that hit or was hit by the objects name was "Spreadable" string.lower is just fancy terms so that the name could be like this "SPreADabLE" now lets make something happen AFTER it checks if it is a part and if the name is spreadable

01script.Parent.Touched:connect(function(hit)
02local f = script.Parent:findFirstChild("Fire")
03 
04if hit.Parent:IsA("Part") then
05x = f:Clone()
06if hit.Parent.Name == string.lower("spreadable") then
07x.Parent = hit.Parent
08end
09end
10end
11end)

now we made the variable x's parent hit.Parent which means the new parent of the cloned fire is what touched the brick

That is a simple way of making it spread from one brick to another.
