A custom wait function In srb2! If you're too lazy to manually make a timer and decrease it every second, you can use this custom wait function

Wait:

  local function Wait(seconds)
    local totalTics = seconds * TICRATE
    local currentTic = 0
 
    return function()
        currentTic = currentTic + 1
        if currentTic >= totalTics then
            currentTic = 0  -- Reset currentTic to prevent acceleration
            return true
        end
        return false
    end
end
end

Basic Principles:

The Wait function MUST be assigned to a variable

Example:

local myTimer = Wait(3)  -- CORRECT
Wait(3)  -- INCORRECT, this will not work

The timer function returns false until the time is complete

Example:

local timer = nil

addHook("PlayerThink", function(player)
    if not timer then
        timer = Wait(3)
    end

    if timer() then
        -- This code runs ONLY after 3 seconds
        P_SpawnMobj(...)
    end
end)

You can continue writing code after calling the timer

Example:

local timer = nil

addHook("PlayerThink", function(player)
    if not timer then
        timer = Wait(3)
    end

    -- Other code can run immediately
    print("Timer started")

    if timer() then
        -- Timed action
        P_SpawnMobj(...)
    end

    -- More code can run
    doSomethingElse()
end)

Multiple timers can exist simultaneously

Example:

local timer1 = nil
local timer2 = nil

addHook("PlayerThink", function(player)
    if not timer1 then
        timer1 = Wait(2)
    end

    if not timer2 then
        timer2 = Wait(5)
    end

    if timer1() then
        -- Runs after 2 seconds
        P_SpawnMobj(...)
    end

    if timer2() then
        -- Runs after 5 seconds
        P_SetObjectMomZ(player.mo, 10*FRACUNIT)
    end
end)

Resetting timers

Example:

local timer = nil

addHook("PlayerThink", function(player)
    if not timer then
        timer = Wait(3)
    end

    if timer() then
        -- Reset timer
        timer = Wait(3)
 
        -- Perform action
        P_SpawnMobj(...)
    end
end)

Remember that
-Timers are not paused, they continue counting(Unless you pause the game)
-Each call to Wait() creates a new independent timer

In a Hook:

local firstTimer = nil
local secondTimer = nil
local state = 0

addHook("PlayerThink", function(player)
    -- State Machine Pattern
    if state == 0 then
        -- Initialize first timer
        firstTimer = Wait(3)  -- Start 3-second timer
        state = 1
    end

    -- First timer check
    if state == 1 and firstTimer() then
        -- Action after first timer completes
        P_SpawnMobj(player.mo.x, player.mo.y, player.mo.z, MT_THOK)
 
        -- Initialize second timer
        secondTimer = Wait(2)  -- Start 2-second timer
        state = 2
    end

    -- Second timer check
    if state == 2 and secondTimer() then
        -- Action after second timer completes
        P_SetObjectMomZ(player.mo, 10*FRACUNIT)
        state = 3  -- Prevent repeated execution
    end
end)

If this is just complex, you can just do Ol' reliable. This was just made for lazy people like you and me, if you are using multiple,

Remember the function WILL NOT STOP until you implement something that stops it

Yipes!:

local timer = Wait(3)  -- 3-second timer
addHook("PlayerThink", function(player)
    if timer() then
        print("3 seconds passed!")
        -- This will print EVERY TIC AFTER the initial 3-second wait
    end
end)

Exaple code but simple:

local function Wait(seconds)
    local totalTics = seconds * TICRATE
    local currentTic = 0

    return function()
        currentTic = currentTic + 1
        if currentTic >= totalTics then
            currentTic = 0  -- Reset currentTic to prevent acceleration
            return true
        end
        return false
    end
end

local timer = nil
local state = 0
local ah = true

addHook("PlayerSpawn", function(p)
    timer = nil
    state = 0
    ah = true
end)

addHook("PlayerThink", function(player)
    if ah == true then
        print("Hey! It's me! Average")
        ah = false
        state = 0
    end

    if state == 0 then
        timer = Wait(3)
        state = 1
    end

    if state == 1 and timer() then
        print("Have fun using the mod you lazy bums")
        timer = Wait(3)
        state = 2
    end

    if state == 2 and timer() then
        print("I am Muy Intelligente")
        timer = Wait(4)
        state = 3
    end

    if state == 3 and timer() then
        print("I am also nice too")
        timer = Wait(4)
        state = 4
    end

    if state == 4 and timer() then
        print("See how (not) easy this it")
        timer = nil
        state = 5
    end
end)
