Math.random help

Help and Feedback Scripting Support
#1

Hey everyone,

As the title states I’m currently looking for some help with math.random property. I’m currently working on a boss fight in one of my games and at certain health points they will teleport around. This is working fine but the problem is the boss teleports to the same point every time making it predictable for the player on future attempts. I tried adding a math.random value to the script with three different locations but i’m honestly quite unfamiliar with the math.random property and have been unsuccessful implementing. I’ve included the script that is currently working well and good and I’ve also included the one I’ve been tinkering around with trying to add math.random in. If anyone could point me in the right direction i’d appreciate it.

while wait() do ----- Waits until Monster is near health threshhold
	if script.Parent.Monster.Health <= 750 then --- Monsters health is at the threshhold now...
		wait(1) ----- Wait a second
		script.parent.HumanoidRootPart.CFrame = CFrame.new(-1846.2, 260.6, 3609.7)
		script:Destroy()--- Teleports Monster to this location
	end
end

Below is my edits to the script to try and make it decide between the three locations via math.random.

local location = math.random(1,3)

while wait() do ----- Waits until Monster is near health threshhold
	if script.Parent.Monster.Health <= 750 then --- Monsters health is at the threshhold now...
		wait(1) ----- Wait a second
		script.parent.HumanoidRootPart.CFrame = location
		if location == 1 then CFrame.new(-1846.2, 260.6, 3609.7)
		elseif location == 2 then CFrame.new(-1575.379, 259.365, 3527.686)
		elseif location == 3 then CFrame.new(-1575.379, 259.365, 3527.686)
	end
	end
	end

Sadly that’s how roblox works, you should try something with chances like in egg systems and give the numbers equal chances.

#3

You will need to call math.random(1,3) each time you want to move to a new location rather than just once at the start.

#4

It is inevitable that everytime he’ll be redirected to the same location yet again because your location variable is not changing every time his health is hitting the relocation point but rather staying frozen

Consider setting location to another randomly generated value under the health check

Consider using Random.new instead of math.random. I hear there is a lot more customizability.

I think I get what you’re doing hopefully this works?

local _locationDict = {
	[1] = Vector3.new(-1846.2, 260.6, 3609.7),
	[2] = Vector3.new(-1575.379, 259.365, 3527.686),
	[3] = Vector3.new(-1575.379, 259.365, 3527.686)
}

local function location(): number
	return Random.new():NextInteger(1, #_locationDict)
end

local healthThreshold;
healthThreshold = script.Parent.Monster:GetPropertyChangedSignal("Health"):Connect(function() -- Instead of using a while loop this detects when the health changes
	if script.Parent.Monster.Health <= 750 then --- Monsters health is at the threshold now...
		wait(1) -- Wait a second
		
		script.Parent:MoveTo(_locationDict[location()]) -- Teleport
		
		-- If you want to destroy the script after it teleports the monster then uncomment this
		--[[
		-- Prevents memory leaks
		healthThreshold:Disconnect()
		healthThreshold = nil
		
		-- Destroys the script
		script:Destroy()
		]]
	end
end)

All you really need to do is to just add more numbers to the dictionary

#8

You need to move this line to the inside of the while loop, or even better, the inside of the if statement. What you are doing is getting a random number and assigning it to location. You only set it once, outside of the loop, and it won’t ever change.

#9

You are setting the “location” once at the start which means it will be the same. Try setting the “location” inside the loop right before you teleport the boss. Also you can use an array with all the locations.

local location

local locations = { -- All the locations
	CFrame.new(-1846.2, 260.6, 3609.7),
	CFrame.new(-1575.379, 259.365, 3527.686),
	CFrame.new(-1575.379, 259.365, 3527.686)
}

while wait() do ----- Waits until Monster is near health threshhold
	if script.Parent.Monster.Health <= 750 then --- Monsters health is at the threshhold now...
		wait(1) ----- Wait a second
		location = locations[math.random(1, #locations)] -- Sets the location to a random item from the list
		script.parent.HumanoidRootPart.CFrame = location
	end
end

Hey this was a nearly perfect solution and was exactly what i was looking to accomplish, i just had to add a script:destroy() at the end to prevent the boss from teleporting over and over. Thanks! And for anyone curious about the finished script I’ve included it below

local location

local locations = { -- All the locations
	CFrame.new(-1846.2, 260.6, 3609.7),
	CFrame.new(-1575.379, 259.365, 3527.686),
	CFrame.new(-1575.379, 259.365, 3527.686)
}

while wait() do ----- Waits until Monster is near health threshhold
	if script.Parent.Monster.Health <= 750 then --- Monsters health is at the threshhold now...
		wait(1) ----- Wait a second
		location = locations[math.random(1, #locations)] -- Sets the location to a random item from the list
		script.parent.HumanoidRootPart.CFrame = location
		script:Destroy()
	end
end
