This part has been negated and is now a union. But as you can see, visually speaking, there are two parts, the top and the bottom. I want to know how I can unanchor the top part so it falls to the ground. I’ve though about getting the position of the cut and replacing the top part with a new part with sizes and positions based on the cut.
This post was placed in the scripting category as the negate process has been done in a script.
It wouldn’t work for anything that isn’t uniform in size and shape but you could just create 2 new parts which mimic the negation. Unfortunately, because of how unions work, I don’t think that’s possible through unioning (although I could be wrong).
It depends on what you want to achieve but it would probably look something like this:
function slicePart()
local newpart1 = part:Clone()
newpart1.Name = "NewPart1"
newpart1.Parent = workspace
newpart1.Size = part.Size - Vector3.new(0,part.Size.y/2,0)
-- If you wanted one part to be larger than the other part you could just change the amount the part size is divided by.
newpart1.Position = (part.Position+Vector3.new(0,part.Size.y/4,0))
-- You can change the position of the part (to make it further away from the second part or closer), currently they are touching.
newpart1.Anchored = false
local newpart2 = part:Clone()
newpart2.Name = "NewPart2"
newpart2.Parent = workspace
newpart2.Size = part.Size - Vector3.new(0,part.Size.y/2,0)
newpart2.Position = (part.Position+Vector3.new(0,-part.Size.y/4,0))
newpart2.Anchored = true
part:Destroy()
end
slicePart()
@ramdom_player201 has the easiest option. I also wrote this function for splitting along an axis if you don’t want to union parts:
local function Split(part: BasePart, axis: Enum.Axis, studs: number)
-- comments are examples when axis is Enum.Axis.X
local first = part:Clone()
local second = part:Clone()
-- (1, 0, 0) for x-axis example
local axisVec = Vector3.FromAxis(axis)
-- (0, 1, 1)
local axisMask = Vector3.new(1, 1, 1) - axisVec
-- can multiply this by axisVec to get (studs, 0, 0)
local studVec = Vector3.new(studs, studs, studs)
-- (0, first.Size.Y, first.Size.Z) + (studs, 0, 0)
first.Size = first.Size * axisMask + studVec * axisVec
-- second.Size - (studs, 0, 0)
second.Size = second.Size - studVec * axisVec
-- vector pointing along part's x axis for example
local worldAxis = part.CFrame:VectorToWorldSpace(axisVec)
-- (part.Size.X, 0, 0)
local sizeAlongAxis = part.Size * axisVec
-- part.Size.X
local len = sizeAlongAxis.X + sizeAlongAxis.Y + sizeAlongAxis.Z
first.CFrame = part.CFrame + worldAxis * (studs - len) / 2
second.CFrame = part.CFrame + worldAxis * studs / 2
-- can remove, just for testing
first.BrickColor = BrickColor.Random()
second.BrickColor = BrickColor.Random()
-- could change this to just return instead of parenting first
first.Parent = workspace
second.Parent = workspace
return first, second
end
-- usage example
local part = workspace.Part
while true do
for _, axis in pairs({Enum.Axis.X, Enum.Axis.Y, Enum.Axis.Z}) do
-- stolen from above function just for random generation
local axisVec = Vector3.FromAxis(axis)
local sizeAlongAxis = part.Size * axisVec
local len = sizeAlongAxis.X + sizeAlongAxis.Y + sizeAlongAxis.Z
local a, b = Split(workspace.Part, axis, math.random() * len)
part.Transparency = 1
wait(1)
a:Destroy()
b:Destroy()
part.Transparency = 0
end
end
