Random events that happen every X minutes

Help and Feedback Scripting Support
#1

Hello everyone!
So what I want to achieve are random events (scripts) that are activated over time.
I mean that every X minutes, an event (power blackout, broken pipes, flood) occurs. But I’ve no clue how to do this.

All help is appreciated. Thanks in advance.

local eventsTable = {
    "Blackout" -- add a comma for more
}

math.random(#eventsTable)
#4

Here’s how my code would go:

wait(math.random(X, Y))
event()

#5

In order to do this you need a list of events (and the corresponding function that makes them run) and a loop that loops every X minutes.

This can be accomplished with RunService and a table

-- get RunService
local RunService = game:GetService("RunService")

-- the table of events
-- to add another event, add another table into the list with name and f
local events = {
    {
        name = "Power Blackout",
        f = function()
            -- code that make the blackout happen
        end
    },
    {
        name = "Flood",
        f = function()
            -- code that make the flood happen
        end
    }
    -- etc
}

local INTERVAL_TIME = 5 * 60 -- this is how long between each event in seconds, so 5 minutes in this case
local timer = 0 -- this will act as our timer, duh 😜

-- this is an event that fires every roblox heartbeat (~30 times per second)
-- it provides the argument dt, which is the amount of time in seconds since the last heartbeat
RunService.Heartbeat:Connect(function(dt)
    timer += dt -- increase the timer

    -- if the timer is greater than the INTERVAL_TIME, then its time to do an event
    if timer > INTERVAL_TIME then
        timer = timer % INTERVAL_TIME -- Reset the timer
        
        -- pick a random event
        local event_index = math.random(#events)

        -- the event, you can do whatever you need to do with these values
        local event = events[event_index]
        local event_name = event.name
        local event_f = event.f

        -- run the funciton and print which event happened
        print("There is a " .. event_name)
        event_f()
    end
end)

If you have any other question about the code, feel free to ask.

local Game = game
local Workspace = workspace
local Players = Game:GetService("Players")

local RandomObject = Random.new()

local EventNames = {"SlowSpeed", "FastSpeed", "LowGravity", "HighGravity", "LowJump", "HighJump"}

local Events = {
	SlowSpeed = function()
		for _, Player in ipairs(Players:GetPlayers()) do
			local Character = Player.Character
			if not Character then continue end
			local Humanoid = Character:FindFirstChildOfClass("Humanoid")
			if not Humanoid then continue end
			Humanoid.WalkSpeed = 8 --Half of default.
		end
	end,
	
	FastSpeed = function()
		for _, Player in ipairs(Players:GetPlayers()) do
			local Character = Player.Character
			if not Character then continue end
			local Humanoid = Character:FindFirstChildOfClass("Humanoid")
			if not Humanoid then continue end
			Humanoid.WalkSpeed = 32 --Double default.
		end
	end,
	
	LowGravity = function()
		Workspace.Gravity = 98.1 --Half of default.
	end,
	
	HighGravity = function()
		Workspace.Gravity = 392.4 --Double default.
	end,
	
	LowJump = function()
		for _, Player in ipairs(Players:GetPlayers()) do
			local Character = Player.Character
			if not Character then continue end
			local Humanoid = Character:FindFirstChildOfClass("Humanoid")
			if not Humanoid then continue end
			Humanoid.JumpPower = 3.6 --Half of default.
		end
	end,
	
	HighJump = function()
		for _, Player in ipairs(Players:GetPlayers()) do
			local Character = Player.Character
			if not Character then continue end
			local Humanoid = Character:FindFirstChildOfClass("Humanoid")
			if not Humanoid then continue end
			Humanoid.JumpPower = 14.4 --Double default.
		end
	end,
}

while true do
	local EventName = EventNames[RandomObject:NextInteger(1, #EventNames)]
	Events[EventName]()
	task.wait(20) --Wait 20 seconds between events.
end

I got side-tracked but I wrote this 10-15 minutes ago. I provided some example events that you can take inspiration from.
