Speed Simulator Walkspeed Help

Help and Feedback Scripting Support
#1

Hi I’m relatvily new to the DevForum website and I’m looking for some help in a basic script I want to do. It’s a Speed Simulator. It’s not a long time project infact I’m doing this for fun, but I want to learn everything I can know. I want to add 1 speed every second that someone moves in any direction.

I’ve made a leaderstats called Speed.
Basic Leaderstat

But the part im confused about is the add 1 speed evey second part.
I think it has something to do with the leaderstats and ‘MoveAnyDirection’ UserInputService. (I’m pretty bad at this scripting name stuff sorry.) If you guys could help me out that would be great! :grinning: Obviously I don’t want you guys to make the script for me but just a bit of guidance from you guys would be great thanks!

I’ve tried the Roblox Developer website but it only gives me search results for ‘Humanoid.Walkspeed’ But that’s partially what I want. If there’s any website links on YouTube or the Roblox Developer website that I missed please link it.

Thanks For Your Guys Help!

I’ll try and break this down bit by bit, so that you not only get the idea of how this particular problem is solved, but the process to do so.

First of all, doing something every one second is our time scale, thisis the first part I would do. That sounds like a while loop.

while true do
wait(1) --Wait a second
---Do something
end

So that will do something every second. Great. But what are we going to do every second. Changing the speed of the character but only if they have moved in any direction. I would start by tackling the first part of that statement. The speed.

You mentioned humanoid walk speed, and that’s exactly what it sounds like. The default player has a humanoid in his character model with a default walk speed of 16. Setting that walk speed to 32 will double the walk speed, and conversely a walk speed of 8 will half it.

humanoid.WalkSpeed = 32 --Double speed
humanoid.WalkSpeed = 16 --Normal speed.
humanoid.WalkSpeed = humanoid.WalkSpeed + 1 --One more speed than before

But how do we get the humanoid to change the walk speed. Lucky every player object has a .Character function that will allow us to get the character, and the character’s humanoid is a child of the character.

if player.Character == nil then
     player.CharacterAdded:Wait() -- If the character has yet to be added, wait for it.
end
player.Character.Humanoid.WalkSpeed = 32 --Sets the players walk speed to x2

Player API reference
Not things are starting to come together. We just need a way of determining if a player moved or not. If I was making this, I would use the character’s position to determine if the player moved in the last second. Store the position before we wait a second, and check if it has changed next time we loop.

local start_pos = player.Character.Head.CFrame.Position --Store the position of the player's head
wait(1) --Wait a second
local distance = (start_pos - player.Character.Head.CFrame.Position).Magnitude --Calculate the distance
if distance > 1 then
    --Do our thing
end

A resource on finding distance between two points

Now we know how to check when to update our speed, how to update our speed, and how to do it every one second.

But what was that leaderstat thing. Simply put, it’s the stats that show on your leaderboard.

Speed.Value = 1 -- One on the leaderboard
Speed.Value = Speed.Value + 1 -- Increment the leaderboard stat
Speed.Value = player.Character.Humanoid.Walkspeed --Set the leader board to reflect the player's walkspeed

I hope this response was not too long, I can get a bit expositional. This should be all the parts needed to assemble the script, you just need to put it together.

Would you need to define / make a variable for the Humanoid part. Or is the script by itself?
Like
Humanoid.Walkspeed = 16
because I’m getting an error at the Humanoid part.

#4

You need a path to the humanoid. The same way you would go

game.Workspace.TargetModel.TargetPart.Transparency = 1 --Is fine

rather than

TargetPart.Transparency = 1 --Produces an error

If your in the player added event, then the easiest path is from the player → character → humanoid

player.Character.Humanoid.WalkSpeed = 32

Yet there is an assumption there that the character is already added to the game. Its is possible for this code to get called before the character is added, hence we have to wait for it

if player.Character == nil then 
     player.CharacterAdded:Wait() -- If the character has yet to be added, wait for it.
end

Did you notice? Don’t bump the topic 5 months ago.

local value = player.leaderstats.Speed.Value -- The speed value
local Char = player.Character -- The players character
local Hum = Char:WaitForChild("Humanoid") -- The players Humanoid
while Hum.MoveDirection.Magnitude > 0 do -- Checking if the humanoid is moving/walking
   value = value + 1 -- Adding one
   wait(1) -- Per second
end)

Idk if this will work but its my idea.

Also if you want to make the players speed the same as the value you should put:

local plr = game.Players.LocalPlayer
local Char = plr.Character
local Hum = Char:WaitForChild("Humanoid")

plr.leaderstats.Speed.Value.Changed:Connect(function()
  Hum.WalkSpeed = Hum.WalkSpeed + 1
end)
