Force to CFrame Not Working

Help and Feedback Scripting Support

#1

So this script used to make a body force to move the part and I changed the BodyForces Force on line 8 to be blasted in the direction the player hit the part but now I want to change its CFrame to in front of where the part was hit in relation the player that touched it instead (Get the same result but instead of adding a force changing its position) but idk how to change line 8 to properly fit CFrame instead of Force

On line 8 I get: Unable to assign property CFrame. CoordinateFrame expected, got Vector3 (Line 8)

If I remove the .LookVector and beyond part of line 8 it doesn’t error, but it doesn’t go in the right direction also I will later make this tween so it doesn’t just teleport the part but transition there

local part = script.Parent 

part.Touched:Connect(function(hit) 
    if hit.Parent:FindFirstChild("Humanoid") then 
        local hum = hit.Parent:FindFirstChild("Humanoid")
        local plr = game.Players:GetPlayerFromCharacter(hum.Parent)
        local HumanoidRootPart = hit.Parent.HumanoidRootPart -- Line Below ▼
        script.Parent.CFrame = CFrame.new(Vector3.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z),part.Position).LookVector * Vector3.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value) -- This Line Here!
    end -- Line above ↑
end)

use PivotTo because it is a model, but use some if statements so you don’t get some errors

hit.Parent:PivotTo(CFrame.new(Vector3.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z),part.Position).LookVector * Vector3.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value))

So now I have this right?:

local part = script.Parent 

part.Touched:Connect(function(hit) 
	if hit.Parent:FindFirstChild("Humanoid") then 
		local hum = hit.Parent:FindFirstChild("Humanoid")
		local plr = game.Players:GetPlayerFromCharacter(hum.Parent)
		local HumanoidRootPart = hit.Parent.HumanoidRootPart
		hit.Parent:PivotTo(CFrame.new(Vector3.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z),part.Position).LookVector * Vector3.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value))
	end
end)

It errors: Unable to cast Vector3 to CoordinateFrame

Also I’m trying to move the part

You are trying to get a lookvector of a vector3, lookvectors are only on cframes, thats why it’s erroing

I did this:

local part = script.Parent 

part.Touched:Connect(function(hit) 
	if hit.Parent:FindFirstChild("Humanoid") then 
		local hum = hit.Parent:FindFirstChild("Humanoid")
		local plr = game.Players:GetPlayerFromCharacter(hum.Parent)
		local HumanoidRootPart = hit.Parent.HumanoidRootPart -- Line Below ▼
		script.Parent.CFrame = CFrame.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z,part.Position).LookVector * Vector3.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value) -- This Line Here! 
	end -- Line above ↑
end)

Now I get Invalid number of arguments: 4 (Line 8)

#6

Now I have this (Not sure if this is how you meant either)

script.Parent.CFrame = CFrame.new(HumanoidRootPart.Position.X,HumanoidRootPart.Position.Z,part.Position).LookVector * CFrame.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value)```

Error: invalid argument #1 (CFrame expected, got Vector3) (Line 8)
#7

You need to put in the first argument of cframe.new as a vector, so you need to put Vector3.new around it

CFrame.new(Vector3.new(HumanoidRootPart.Position.X,HumanoidRootPart.Position.Z,part.Position).LookVector * CFrame.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value))

Error: LookVector is not a valid member of Vector3 (Line 8)

#9 
CFrame.new(Vector3.new(HumanoidRootPart.Position.X, 0, HumanoidRootPart.Position.Z),part.Position).LookVector * CFrame.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value)

Also when you set the part’s cframe you have to multiply by current cframe too or it wont be in the right place

I appreciate your help! This now says: invalid argument #1 (CFrame expected, got Vector3)

local part = script.Parent 

part.Touched:Connect(function(hit)

		local HumanoidRootPart = hit.Parent.HumanoidRootPart -- Line Below ▼
		script.Parent.CFrame = CFrame.new(CFrame.new(Vector3.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z),part.Position).LookVector + Vector3.new(300 * plr.HitPower.Value, 20, 300 * plr.HitPower.Value)) -- This Line Here!

Thank you! this doesn’t error out, but it doesn’t go in the direction I hit it. Do you know why?

#14

Did you want it to go in 300 * HitPower from the LookVector and up 20 studs?

#15 
local part = script.Parent 

part.Touched:Connect(function(hit) 
	if hit.Parent:FindFirstChild("Humanoid") then 
		local hum = hit.Parent:FindFirstChild("Humanoid")

		local HumanoidRootPart = hit.Parent.HumanoidRootPart -- Line Below ▼
		local HumToPart = CFrame.new(Vector3.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z),part.Position).LookVector
		script.Parent.CFrame = CFrame.new((HumToPart * (300 * plr.HitPower.Value)) + Vector3.new(0,20,0)) -- This Line Here!

That multiplier used to work correctly on a body force but I’m assuming its very different using CFrames. I want it to go forward a bit and have it so I can multiply it by the Hit Power if that makes sense. its for a hockey puck so I want it to blast in the direction a player hit it and I will turn it into tween I just wanted to figure out how to do this first.

#17

Well, I wouldn’t recommend tweening it since it can’t be stopped by anything it hits. You could try settings it’s Velocity to (LookVector * (300*HitPower)) + Vector3.new(0,20,0).

local part = script.Parent 

part.Touched:Connect(function(hit) 
	if hit.Parent:FindFirstChild("Humanoid") then 
		local hum = hit.Parent:FindFirstChild("Humanoid")
		local plr = game.Players:GetPlayerFromCharacter(hum.Parent)
		local HumanoidRootPart = hit.Parent.HumanoidRootPart -- Line Below ▼
		local HumToPart = CFrame.new(Vector3.new(HumanoidRootPart.Position.X,hit.Position.Y,HumanoidRootPart.Position.Z),part.Position).LookVector
		script.Parent.Velocity = (HumToPart * (300 * plr.HitPower.Value)) + Vector3.new(0,20,0) -- This Line Here!
	end -- Line above ↑
end)

That actually works quite well but my only concern is that I couldn’t use physics because of NetWork Owner lag between Mobile and PC players crossed over.

#19

Hmm… Maybe you could split the visualization from the physics - ie. have a server-owned puck that handles physics, but players don’t see it, and then have a client-owned puck for only for visualization.

One way of doing it would be using the Velocity on both client & server, but destroy the client puck when the server puck has stopped, and then make the server puck visible.

You must choose which way you want to visualize your puck.

Ok, thank you for all of your help I really appreciate it! I’ll let you know if it works.
