Hi, I’ve been trying to make something that creates pyramids using corner wedge parts. 4 of these will make up a perfect pyramid, I’ve figured out how to position 2 of the 4 pieces, and I’ve been struggling with the 3rd and 4th pieces.
Here’s what I have so far:
local function findSurface(basePart, surface)
local origin = basePart.Position;
local size = basePart.Size;
local x, z = size.X, size.Z;
local P = {
x0 = CFrame.new(origin) * CFrame.new(x * 0.5, 0, 0).p;
y0 = CFrame.new(origin) * CFrame.new(0, 0, z * 0.5).p;
x1 = CFrame.new(origin) * CFrame.new(-x * 0.5, 0, 0).p;
y1 = CFrame.new(origin) * CFrame.new(0, 0, -z * 0.5).p;
};
return P[surface];
end;
local function createPyramid()
local c1 = Instance.new("CornerWedgePart");
c1.Anchored = true;
c1.CanCollide = false;
c1.Parent = workspace;
local c2 = c1:Clone();
c2.Anchored = true;
c2.Position = findSurface(c1, "y0");
c2.CFrame = c2.CFrame:Inverse() * CFrame.Angles(0, -math.rad(90), 0);
c2.Position = c2.Position + Vector3.new(0, 0, -c1.Size.Z / 2)
c2.Parent = workspace;
local c3 = c1:Clone();
c3.Anchored = true;
c3.Position = findSurface(c2, "x0");
c3.CFrame = c3.CFrame:Inverse() * CFrame.Angles(0, math.rad(180), 0);
c3.Parent = workspace;
end;
I’ve been messing around with the script for a while, and I’ve gotten to something that sort of looks like a pyramid. It works when the size is set to something larger, however when the size is something like [1, 1, 1], the corner wedge parts are more spaced out making it look a lot less like a pyramid. If anybody knows how to fix this, please let me know.
local function findSurface(basePart, plane)
local origin = basePart.Position;
local size = basePart.Size;
local x, z = size.X, size.Z;
local P = {
x0 = CFrame.new(origin) * CFrame.new(x * 0.5, 0, 0).p;
y0 = CFrame.new(origin) * CFrame.new(0, 0, z * 0.5).p;
x1 = CFrame.new(origin) * CFrame.new(-x * 0.5, 0, 0).p;
y1 = CFrame.new(origin) * CFrame.new(0, 0, -z * 0.5).p;
};
return P[plane];
end;
local function createUnion(parts)
local u = parts[1]:UnionAsync(parts);
for _, part in ipairs(parts) do
part:Destroy();
end;
return u;
end;
local function createCrystalTop(o, s)
local s = s or 1;
local c1 = Instance.new("CornerWedgePart");
c1.Anchored = true;
c1.Position = o or Vector3.new();
c1.Size = Vector3.new(s, s, s);
c1.CanCollide = false;
c1.Parent = workspace;
local c2 = c1:Clone();
c2.Position = findSurface(c1, "y0");
c2.CFrame = c2.CFrame:Inverse() * CFrame.Angles(0, -math.rad(90), 0);
c2.Position = c2.Position + Vector3.new(0, 0, -c1.Size.Z / 2);
c2.Parent = workspace;
local u1 = createUnion{c1, c2};
u1.Parent = workspace;
local u2 = u1:Clone();
u2.Position = findSurface(u1, "x0");
u2.CFrame = u2.CFrame:Inverse() * CFrame.Angles(0, math.rad(180), 0);
u2.Position = u1.Position + Vector3.new(u1.Size.X, 0, 0);
u2.Parent = workspace;
local finalUnion = createUnion{u1, u2};
finalUnion.Parent = workspace;
end;
createCrystalTop(nil, 2);
I figured it would be easier to get the first 2 corners, turn it into a union and then turn it around.
local offsets = {
Vector3.new(-0.25, 0, 0.25),
Vector3.new(0.25, 0, 0.25),
Vector3.new(0.25, 0, -0.25),
Vector3.new(-0.25, 0, -0.25),
}
local function createPyramid(center, size)
local model = Instance.new("Model")
for i = 1, 4 do
local wedge = Instance.new("CornerWedgePart")
if i%2 == 0 then
wedge.Size = Vector3.new(size.Z / 2, size.Y, size.X / 2)
else
wedge.Size = Vector3.new(size.X / 2, size.Y, size.Z / 2)
end
wedge.CFrame = CFrame.new(center + offsets[i]*size) * CFrame.Angles(0, (i-1)*math.pi/2, 0)
wedge.Anchored = true
wedge.Parent = model
end
return model
end
-- usage example
local center = Vector3.new(0, 3, 0)
local size = Vector3.new(10, 4, 6)
local p = createPyramid(center, size)
p.Parent = workspace
