Wait statement not working

Help and Feedback Scripting Support
#1

I am making a restaurant game where the food does random effects, and I want to make it that it will speed up the player, wait 5 seconds, slow down the player, wait another 5 seconds, and then make the walkspeed normal, but the wait() statements aren’t working

	caffeine = function(plr)
		local val = 24
		task.spawn(function()
			local char = plr.Character
			local hum = char:WaitForChild("Humanoid")
			local Info = TweenInfo.new(2)
			local Tween = game:GetService("TweenService"):Create(hum,Info,{WalkSpeed=val})
			Tween:Play()
			task.wait(5)
			val = 12
			Tween = game:GetService("TweenService"):Create(hum,Info,{WalkSpeed=val})
			Tween:Play()
			task.wait(5)
			val = 16
			Tween = game:GetService("TweenService"):Create(hum,Info,{WalkSpeed=val})
			Tween:Play()
		end)

Tween:Play() does not yield. Tweens play asynchronously, meaning task.wait(5) runs immediately after Tween:Play(), potentially causing issues if the tween isn’t finished before the next step.

caffeine = function(plr)
	local char = plr.Character
	if not char then return end
	local hum = char:FindFirstChild("Humanoid")
	if not hum then return end

	local tweenService = game:GetService("TweenService")
	local info = TweenInfo.new(2)

	task.spawn(function()
		-- Speed Up
		local tween = tweenService:Create(hum, info, {WalkSpeed = 24})
		tween:Play()
		tween.Completed:Wait() -- Ensure the tween fully plays
		task.wait(5)

		-- Slow Down
		tween = tweenService:Create(hum, info, {WalkSpeed = 12})
		tween:Play()
		tween.Completed:Wait()
		task.wait(5)

		-- Normalize
		tween = tweenService:Create(hum, info, {WalkSpeed = 16})
		tween:Play()
	end)
end

Hope this helps :slightly_smiling_face:

This still doesn’t work

Could you provide me with more information? What is the issue exactly? Maybe a video too would help.

LocalScript, tested and working …

local TweenService = game:GetService("TweenService")
local Players = game:GetService("Players")

local function caffeine()
	local plr = Players.LocalPlayer
	local char = plr.Character or plr.CharacterAdded:Wait()
	local hum = char:FindFirstChildOfClass("Humanoid")
	if not hum then return end

	local function tweenWalkSpeed(speed, duration)
		local tween = TweenService:Create(hum, TweenInfo.new(duration, Enum.EasingStyle.Linear), {WalkSpeed = speed})
		tween:Play() task.wait(duration)
	end

	tweenWalkSpeed(24, 2) task.wait(5)
	tweenWalkSpeed(12, 2) task.wait(5)
	tweenWalkSpeed(16, 2)
end

task.wait(5) --so I have time to get to and see WalkSpeed changing, while testing
caffeine()

I believe your issue was not waiting for the tween to finish.
tween:Play() task.wait(2) … or
tween:Play() tween.Completed:Wait() … or
tween:Play() task.wait(duration) … as I passed duration

This, in turn, threw off the overall timing.
I’m not sure why you would want to use task.spawn() here.

This doesnt work, (i forgot to mention that this is in a module script)

#7

This works, I tested it myself. You may have to reformat it for your module.
