How To Use BodyPosition

Introduction

In this tutorial, you should be in ROBLOX STUDIO, and also, you should be at least a INTERMEDIATE SCRIPTER.

Setup

Alright, let's begin. First, make a small brick. I made mine 5x1x5. Next, select the brick you just made and click Insert->Object->Script. Now double-click the new script object. You should see the following:

 print("Hello World!") 

Delete it, you won't need it.

Code

First, add this code.

 function onTouched(hit) 

This will detect when something touches it.

local h = hit.Parent:findFirstChild("Humanoid")
if h ~= nil then

This will detect wether what touched it was a human or not. You don't want a rocket or slingshot to activate it, do you?

local b = Instance.new("BodyPosition")

Ok, this defines our Bodyposition. But right now it doesn't do anything, because it doesn't have a parent.

b.position = (500, 500, 500)
b.maxForce = (500000000, 500000000, 500000000)
b.Parent = hit.Parent.Torso

This will define some of BodyPosition's properties. I'll explain each one. BodyPosition's position property does this: When a BodyPosition has a parent, it will make the parent fly to the BodyPosition's position property. It's great for a lot of things, like teleporting without teleporting. Next we have the maxForce property. Simply put, it's how much force can be put on each axis of the parent brick. It also governs how far away the BodyPosition can be from it's position property before it will take a brick there. Finally, the Parent of the BodyPosition is what the BodyPosition will be moving, in this case, the character's torso. So far we have this:

function onTouched(hit)
  local h = hit.Parent:findFirstChild("Humanoid")
  if h ~= nil then
    local b = Instance.new("BodyPosition")
    b.position = (500, 500, 500)
    b.maxForce = (500000000, 500000000, 500000000)
    b.Parent = hit.Parent.Torso

Alright, this is great. You'll fly to the point. But when will you drop? Thats a problem we have to fix. Let's try this:

wait(3)
b.Parent = nil

Great! Now after 3 seconds, the BodyPosition ceases to exist, and you will drop! Now we just have to clean up the functions, and actually connect it to the Touched property!

  end
end
script.Parent.Touched:connect(onTouched)

There we go! those ends end the if statement and the function. Let's see the whole script.

function onTouched(hit)
  local h = hit.Parent:findFirstChild("Humanoid")
  if h ~= nil then
    local b = Instance.new("BodyPosition")
    b.position = (500, 500, 500)
    b.maxForce = (500000000, 500000000, 500000000)
    b.Parent = hit.Parent.Torso
    wait(3)
    b.Parent = nil
  end
end
script.Parent.Touched:connect(onTouched)

If you want to change where the character flies to, then you can change the BodyPosition's position property. Also, something really fun is if you only wait(0.1) then the character goes flying!
