i tryed doing it but i just failed so i just made zombies spawn evry bit i need help makeing them in waves and add more zombies hears my script

end

You can put an inner loop inside the outer spawn loop to control how many zombies you want to spawn each time through the spawn loop. Something like this:

-- How long to wait between spawns
local timeBetweenSpawns = 10

-- How many zombies to spawn each wave
local zombiesToSpawn = 5

while true do
	for i = 1, zombiesToSpawn do
		local Chance = math.random(1,10)
		if Chance == 7 then
			SpawnEnemy("strong zombie")
		else
			SpawnEnemy("zombie")
		end
	end
	
	wait(timeBetweenSpawns)
end
