How could you check if theres a brick right next to a part or not?

How could you check if theres a brick right next to a part or not? This question was based off of those mining games on roblox where they add the illusion of a endless mining area while all they do is add bricks Is this achieved by raycasting on each side to check if theres a brick. Also how could i check if a player is facinga brick with lookvector?

You can get an array of parts touching it. Using :GetTouchingParts()

parts = script.Parent:GetTouchingParts()

You can use the # Operator to see how many of something is in a table, so if it's 0, nothing is touching it.

parts = script.Parent:GetTouchingParts()
if #parts >= 0 then
	print("No parts touching")
end

Now because it's a table we could do special things with it like use a generic for loop.

parts = script.Parent:GetTouchingParts()

for _,part in pairs(parts) do
	print(part.Name.." is touching my parent.")
end

#Final Product

local parts

while wait() do --Not the best way to do this
	parts = script.Parent:GetTouchingParts()
end

Hope it helps!

#Other Stuff DragonODeath gave me an idea. I thought about using the Touched event. I thought about it before and realized it isn't very reliable, but I thought of a solution:

parts = {}

function NotOnTable(part)
	for _,p in pairs(parts) do
		if part ~= p then
			return false
		end
	end
	return true
end

script.Parent.Touched:connect(function(p)
	if NotOnTable(p) then
		local pos = #parts+1
		table.insert(parts, p,pos)
		local num = Instance.new("IntValue", p)
		num.Name = "TableThingForScript"
		num.Value = pos
	end
end)

script.Parent.TouchEnded:connect(function(p)
	for _,pa in pairs(parts) do
		if pa == p  and p:FindFirstChild("TableThingForScript") then
			table.remove(parts,p.TableTingForScript.Value)
			p.TableThingForScript:Destroy()
		end
	end
end)
