How could I make a VectorForce follow the players mouse?

#1

Hey devs!

I’m trying to make plane physics in Roblox and I’m using a vector force to make the plane move, I want the vector force to follow the mouse position so the plane moves in the direction of the players mouse.

How could I do this?

Or is there a better way to make plane physics? Let me know!

Any help appreciated!

you could calculate the Vector3 direction by getting the difference between Mouse.Hit and Camera.CFrame, then doing .Unit to it

then multiply that by how much force you want to apply

Could you explain how this would help?

oh, forgot to mention that you’d change both CFrames to Vector3s of their positions, but here’s an example of getting the direction between 2 Vector3s

local Part1 = workspace.A
local Part2 = workspace.B

-- line segment vector3 from A to B
-- this would be (0,0,100) if A is at (0,0,23) and B is at (0,0,123)
local fromAToB = Part2.Position - Part1.Position

-- distance from A to B
print(fromAToB.Magnitude)

-- direction from A to B
-- this looks like (0,0,-1) or (0,.707,-.707) or (1,0,0)
print(fromAToB.Unit)

this is info on getting the mouse Mouse | Roblox Creator Documentation

Something like this might work:
local part = script.Parent

local function onMouseMove(mousePosition)
local force = mousePosition - part.Position
force = force.Unit * 100
part:ApplyForce(force)
end

script.Parent.Touched:Connect(onMouseMove)

The idea is to take the difference between the part’s position and the mouse position. This will give you a vector that points in the direction of the mouse from the part. Then we normalize it to get a unit vector, and multiply it to get a force of the desired magnitude. Finally we apply the force to the part.
