How to make propulsion

Help and Feedback Scripting Support
#1

I am trying to make an hammer that push parts when it hit.

I have no clue how to do that, maybe using explosions, body-gyro or event vector-force ?!

I would like to have your idea about the question.

  • I juste started scripting in LuaU not so long ago so I mostly use drive-seat part to move other parts, or special joints. I even made a pickaxe recently that detect specific part to break them as the terrain, so I already have the base of my script as the detection of the part I wanna propuls. So I even know how to modify things in the part. I mean I have an access to my part and know how to change his parameters.

So this is how I detect for know.

for_, touching in pairs(workspace:GetPartBoundsInRadius(collider.Position,collider.size.X/2)) do
   if touching.Name == "Box" then
       print("Box touched !!!")
       local box = touching
       --here I Wana propulse box
       break
   end
end

(Also this is my first post on the dev forum so I may have forgot things that can be helpful so don’t hesitate to ask me :D)

Also thank you for reading.

I would suggest using vector force for this.,

Something like

        local vectorForce = Instance.new("VectorForce")
        vectorForce.Force = Vector3.new(0, 0, 1000)  -- Adjust the force as needed
        vectorForce.RelativeTo = Enum.ActuatorRelativeTo.World
        vectorForce.Parent = box
        vectorForce.Enabled = true

It would obviously have to have more added to it and things, but theres a baisc starting point. It would also need customizing to your needs.

Thank you for you answer.

I am not sure how to use that, may I change the relativeto to the center of mass of my box ?
And I must make a new attachment to my box to know where to put my vector?

And I can change the direction where my part is propulse by changing vector.Force ?

Am gonna try this

So I tried to use the Vector Force, I even looked up some documentation but I can’t figure how to correctly select the direction where my part must go.

Because it seems the part always go to his own X and never the X of the hammer which is bad because the part can go on you while you hit the box.

So I try to us the “collider” which is in the hammer but then the player get recoil, it’s a cool effect by the way but not what am trying to do.

So I think my problem is in the

vectorForce = Vector3.new(",",")

Because I don’t get how I can set the direction with something else than the box’s X,y and z.

Here is what I have for now

local box
local vectorForce = Instance.new("VectorForce")
local attachmentHit = Instance.new("Attachment")

attachmentHit.Parent = box
attachmentHit.Worldposition = collider.Position

vectorForce.Parent = box
vectorForce.RelativeTo = Enum.ActuatorRelativeTo.Attachement0
vectorForce.Attachement0 = attachmentHit
vectorForce.Force = Vector3.new(10000,5000,0)

So I think If I can make the attachmentHit being always up it may work whatever the angle.

Let me have a look.

-- Assuming 'collider' is the hammer
local collider = script.Parent  -- Adjust this to the actual hammer part

for _, touching in pairs(workspace:GetPartBoundsInRadius(collider.Position, collider.Size.X / 2)) do
    if touching.Name == "Box" then
        print("Box touched!")
        local box = touching

        -- Create a VectorForce inside the 'Box'
        local vectorForce = Instance.new("VectorForce")
        vectorForce.Force = Vector3.new(0, 0, 1000)  -- Adjust the force as needed
        vectorForce.RelativeTo = Enum.ActuatorRelativeTo.World
        vectorForce.Parent = box
        vectorForce.Enabled = true

        -- Optional: You can also destroy the VectorForce after a certain time
        wait(1)  -- Adjust the duration
        vectorForce:Destroy()

        break
    end
end

This will have to be changed to your needs, but it would look something like this I think.
