How do you track the distance a player has moved?
I am trying to create a script for my game that tracks the distance a player has moved, but I seem to not be able to find any information on the topic.

A way you can track the amount a player moved is by using magnitude. The magnitude is essentially the length of the vector.
So what you can do is actually save the original position of the character's HumanoidRootPart, and their current position. From there, we can get the direction vector of those two positions by subtracting both vectors. Finally, use magnitudeto get the length of this direction vector.
01 | local PS = game:GetService("Players") |
02 | local Player = PS.LocalPlayer |
03 | local Character = Player.Character or Player.CharacterAdded:Wait() |
04 | local RootPart = Character.HumanoidRootPart |
05 |
06 | local LastPosition = RootPart.Position |
07 |
08 | local distance = 0 |
09 |
10 | while true do |
11 | --Lower the wait time for more precise measurements. |
12 | wait(1) |
13 | local CurrentPosition = RootPart.Position |
14 | --Here we get the length of the direction vector by using magnitude. |
15 | local length = (LastPosition - CurrentPosition).magnitude |
This is obviously in a LocalScript. If you really wanted to track the player's movement through the server, it is recommended to create a leaderstats value, and you can track the distance through the Player.CharacterAdded event.
There should be a StarterCharacterScripts script, like this:
01 | local PreviousPosition, ActualPosition = script.Parent.HumanoidRootPart.Position |
02 | local DistanceMoved = 0; |
03 |
04 | while wait() do |
05 | ActualPosition = script.Parent.HumanoidRootPart.Position |
06 |
07 | DistanceMoved = DistanceMoved + ((ActualPosition.X + ActualPosition.Z) - (PreviousPosition.X + PreviousPosition.Z)).magnitude |
08 |
09 | PreviousPosition = ActualPosition |
10 | end |
What it does is that it has two variables, one which tracks the previous position, and the other one which tracks the actual position inside the while loop.
Inside the while loop the actual position is set again, so in some cases it should be different, and then the DistanceMoved variable gets bigger with the distance movedby the character, which is the opperation ((ActualPosition.X + ActualPosition.Z) - (PreviousPosition.X + PreviousPosition.Z)).magnitude.
