Is the part a model or a normal part?

Can I see the structure of the part?



You’re trying to set the position of a model, you can move an entire model via the MoveTo method of Models or to move a specific part, just reference it, you’d have to have different names for them, what is your code?

To fix this you will firstly need to weld the first part to the other with a weld constraint then set the primary part of the model to the first part and then in your script do this:

local beam = game:GetService("ReplicatedStorage"):WaitForChild("Beam"):Clone()
			local explosion = game:GetService("ReplicatedStorage"):WaitForChild("Explosion"):Clone()
			local hrp = character:FindFirstChild("HumanoidRootPart")
			beam.Parent = workspace
			beam.CFrame = hrp.CFrame *,0,-2)
			local bv ="BodyVelocity", beam)
			bv.MaxForce =,math.huge,math.huge)
			bv.Velocity =, Value2).lookVector * 100
			if hit.Parent.Name == Player.Name then return end
			if hit.Parent.Name ~= Player.Name and hit.Parent:FindFirstChild("Humanoid")  then
				explosion.Position = beam.Position
				explosion.Parent = workspace
				local TweenService = game:GetService("TweenService")
				local Info =, Enum.EasingStyle.Linear, Enum.EasingDirection.Out, 0, false, 0)
				local properties = {
					Size =,5,5), 

				local Tween = TweenService:Create(explosion, Info, properties)

I want to put the explosion in the position of the beam

Change this

explosion.Position = beam.Position

To this

it will not move to the position of the beam

Ill watch the weld tutorial first

Okay so I did some research and Beams don’t have a position property. You have to either use Attachment0 (Start position of beam) or Attachment1 (End position of Beam) and use their CFrame


Or you could directly reference their Position without using CFrame.Position

Maybe this’ll work?

It doesnt, it says

But it works if I weld the parts.

Thanks for the help both of you<3

Huh? Beams hae 2 Attachments on them, I’m not sure what’s happening there, but I guess it’s okay if you weld them together, does it at least position it correctly now?.

Also your tween isn’t working cause a model doesn’t have the Size property, you have to make it tween the parts in the model instead

the beam that I was using is a just another fireball, thats why it doesnt have attachments. Thanks for the advice in the model it works now.

Ohhh, I thought you meant an actual beam thing haha. Are you still having issues with the position not working?

The position now works, same with tween
