Script randomly errors

[the_best3334 (MrCoolDude)]

I have a script that randomly generates a map made of hexagonal tiles, and sometimes a loop in it errors, specifically the for i,v in ipairs(hexes) do

local function generateMap()

	repeat

		local t = {}

		for i,v in ipairs(hexes) do

			local angle = 30
			local pos = v.CFrame.Position

				for i2=1,6 do
					if hexAmount == maxHexAmount then
						break
					end
					local dir = (CFrame.new(pos)*CFrame.fromEulerAnglesXYZ(0,math.rad(angle),0)).LookVector*3.132
					local result = workspace:Raycast(pos,dir,rp)

					if not result and math.random(1,chance) == 1 then

						hexClone = hexTile:Clone()
						hexClone.Parent = map
						hexClone.CFrame = CFrame.new(pos+dir)
						table.insert(t,hexClone)
						hexAmount += 1

					end

					angle += 60

				end

			if i % 5 == 0 then task.wait() end

		end

		if #t > 0 then
			hexes = t
		end

	until hexAmount >= maxHexAmount
end

add a task.wait(.05) in all of the loops.
this adds some execution time, and does not force the script to execute fast
