Molotov throws backwards

[Miserable_Haven]

I made a script that sends the mouse LookVector to server, then the server throws Molotov based on the Lookvector. The problem is that when facing one direction it throws backwards.

Server:

script.Action.OnServerEvent:Connect(function(plr,mousehitpos,mouselookvector)
	
	local Handle = script.Parent.Handle:Clone()
	local d = script.Parent.Handle
	d.Transparency = 1
	local Velocity = Instance.new("LinearVelocity")
	local Multiply = 35
	local Yforce = (mouselookvector.Y*Multiply)
	local Zforce = -(mouselookvector.Z*Multiply+2)
	print(Yforce.." / "..mouselookvector.Y)
	print(Zforce.." / "..mouselookvector.Z)
	Velocity.VectorVelocity = Vector3.new(0,Yforce,Zforce)
	Velocity.Parent = Handle
	Velocity.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
	Velocity.Attachment0 = Handle:FindFirstChildWhichIsA("Attachment")
	game.Debris:AddItem(Velocity,.2)
	Handle.Transparency = 0
	Handle.Position = d.Position
	Handle.Name = "Molotov"
	Handle.CanCollide = true
	Handle.CanTouch = true
	Velocity.MaxForce = 1000
	
	Handle.Parent = workspace
	Handle.Explode.Disabled = false

end)

Client:

--// Functions

local function Throw()
	script.Parent.Action:FireServer(Mouse.Hit.Position,Mouse.Hit.LookVector)
end

--// Script

wait(1)

Tool.Activated:Connect(function()
	Throw()
end)

The only direction it throws correctly is this direction.

Rotating 90 degrees or -90 degrees will cause it to have no velocity and not throw. Rotating 180 degrees from that point will make it throw backwards.

can’t you just reverse the velocity’s force?

[Miserable_Haven]

If I do that, then the direction it throws backwards is going to be the other way around. It will still throw backwards one direction

[sussy_bacoo]

i don’t really understand, please explain

[Miserable_Haven]

When the client sends the mouse LookVector to the server, the server multiplies the lookvector on the Y and Z axis. Then it applies that velocity to the molotov using Linear Velocity. The problem is that when facing the other direction and sending the mouses LookVector to the server, it does not reverse.

[sussy_bacoo]

maybe reverse the yorce and the zforce

[Miserable_Haven]

The ZForce is already reversed. If I reverse the YForce, it would still throw backwards

[crashedthe911 (saint)]

Have you tried instead of multiplying the YForce and ZForce, just directly referencing mouselookvector as the velocity?

[Miserable_Haven]

I have tried that, but it returns a decimal for LookVector, so it applies something like 0.3481596186, which means it does not have any power when throwing it

[crashedthe911 (saint)]

This might not work but what if you used math.ceil to round to the nearest integer and then multiplying mouselookvector with Multiply?

mouselookvector * Multiply

[Miserable_Haven]

I used Math.Ceil but it returns 0

	local Yforce = math.ceil((mouselookvector.Y--[[*Multiply]]))
	local Zforce = math.ceil(-(mouselookvector.Z--[[*Multiply+2]]))

[crashedthe911 (saint)]

@Miserable_Haven

local Zforce = -(mouselookvector.Z*Multiply+2)

What about, instead of reversing the whole Zforce, you just reversed the multiplication?

mouselookvector.Z * -Multiply

or

Velocity.VectorVelocity = Vector3.new(0, mouselookvector.Y * -Multiply, mouselookvector.Z * -Multiply)

[Doryisafish]

quick question (sorry if this is a bit unrelated)

why is there no XForce variable here

	local Handle = script.Parent.Handle:Clone()
	local d = script.Parent.Handle
	d.Transparency = 1
	local Velocity = Instance.new("LinearVelocity")
	local Multiply = 35
	local Yforce = (mouselookvector.Y*Multiply)
	local Zforce = -(mouselookvector.Z*Multiply+2)
	print(Yforce.." / "..mouselookvector.Y)
	print(Zforce.." / "..mouselookvector.Z)
	Velocity.VectorVelocity = Vector3.new(0,Yforce,Zforce)

[Miserable_Haven]

I just used the cameras CFrame at Y

script.Action.OnServerEvent:Connect(function(plr,mousehitpos,mouselookvector,camcframe)
	if db == true then
		return
	end
	db = true
	local Handle = script.Parent.Handle:Clone()
	local d = script.Parent.Handle
	d.Transparency = 1
	local Velocity = Instance.new("LinearVelocity")
	local Multiply = 4
	local Yforce = math.floor(camcframe.Y/2*Multiply)
	local Zforce = -math.floor(Yforce*Multiply)
	print(Yforce.." / "..mouselookvector.Y)
	print(Zforce.." / "..mouselookvector.Z)
	Velocity.VectorVelocity = Vector3.new(0,Yforce,Zforce)
	Velocity.Parent = Handle
	Velocity.RelativeTo = Enum.ActuatorRelativeTo.Attachment0
	Velocity.Attachment0 = Handle:FindFirstChildWhichIsA("Attachment")
	game.Debris:AddItem(Velocity,.2)
	Handle.Transparency = 0
	Handle.Position = d.Position
	Handle.Name = "Molotov"
	Handle.CanCollide = true
	Handle.CanTouch = true
	Velocity.MaxForce = 1000
	
	Handle.Parent = workspace
	Handle.Explode.Disabled = false
	wait(5)
	db = false
	d.Transparency = 0

end)

	script.Parent.Action:FireServer(Mouse.Hit.Position,Mouse.Hit.LookVector,workspace.CurrentCamera.CFrame)
end

variable’s still say mouselookvector but it’s the camera
