How does vectorForce work?

Help and Feedback Scripting Support
#1

Im trying to use a VectorForce to move the character around.

There character is a ball and I’m trying to move it, I was told to use VectorForce.

Anyhow it should make the character move but its not! The character isnt anchored or anything, I dont understand why though.

Well heres some code I use to modify it.

local char = script.Parent
wait(1)

local force = char:FindFirstChild('Torso'):FindFirstChild('Force')

-- force
force.Force = Vector3.new(math.huge,math.huge,math.huge)
force.ApplyAtCenterOfMass = true
#2

You can see this documentation. Attachments must be used

You also need to calculate the direction in your script.

Tried this, I still cant figure it out

#5 
local char = script.Parent
wait(5)

local force = Instance.new("VectorForce")
local torso = char:WaitForChild("UpperTorso")
local attachment = Instance.new("Attachment")
force.Attachment0 = attachment
force.Force = Vector3.new(0, 10000, 0)
force.ApplyAtCenterOfMass = true
attachment.Parent = torso
force.Parent = torso

Use this script in StarterCharacterScripts. This script will make your character fly up

#6

Is this a server script or local script? If local as Im assuming its not working at all, The attachment and Force appear but nothing happens. The character is still just sitting there

#7

This is a local script in StarterCharacterScripts

#8

Can u record a video what happen when u start the game?

#9

Nothing happens, the character just sits there

  • The VectorForce constraint in Roblox applies a constant force to an assembly.
  • The force’s direction and strength are determined by a Vector3 and can be relative to an attachment on the part, another attachment, or the world coordinate system.
  • If only initial velocity is needed, set the AssemblyLinearVelocity property directly on the assembly.
  • To maintain a more steady velocity over time, use a LinearVelocity constraint instead of VectorForce.
  • Very high speeds may result when using VectorForce without other forces involved.
  • When configuring the constraint, understanding Roblox Units and how they compare to metric units can be helpful.
  • By default, the force is applied to the assembly at the location of Attachment0, which may introduce torque if the center of mass is not aligned with the force’s direction.
  • To focus the force at the center of mass, the ApplyAtCenterOfMass option can be toggled on.
  • By default, the force is applied relative to Attachment0, meaning it changes direction as the parent assembly rotates.
  • Setting RelativeTo to World applies the force in world coordinates, independent of parent or attachment orientations.
  • Setting RelativeTo to Attachment1 applies the force relative to Attachment1, and it changes direction with the attachment’s rotation.
