Creating an Icosahedron (EditableMesh)

#1

Some code I made for creating an icosahedron based on this article: catch 22 - Andreas Kahler's blog: Creating an icosphere mesh in code. I hope this helps you alot, I’m still kinda new to posting interesting stuff on the Devforum and would appreciate any feedback.
Icosahedron

local t = (1+math.sqrt(5))/2;
local icosahedronVerts = {
	Vector3.new(-1,t,0),
	Vector3.new(1,t,0),
	Vector3.new(-1,-t,0),
	Vector3.new(1,-t,0),

	Vector3.new(0,-1,t),
	Vector3.new(0, 1, t),
	Vector3.new(0,-1,-t),
	Vector3.new(0,1,-t),

	Vector3.new(t,0,-1),
	Vector3.new(t,0,1),
	Vector3.new(-t,0,-1),
	Vector3.new(-t,0,1),
}

local icosahedronTris = {
	{1,12,6},
	{1,6,2},
	{1,2,8},
	{1,8,11},
	{1,11,12},

	{2,6,10},
	{6,12,5},
	{12,11,3},
	{11,8,7},
	{8,2,9},

	{4,10,5},
	{4,5,3},
	{4,3,7},
	{4,7,9},
	{4,9,10},

	{5,10,6},
	{3,5,12},
	{7,3,11},
	{9,7,8},
	{10,9,2},
}

local function Generate()
	local Part = Instance.new("MeshPart",workspace)
	Part.Name="Icosahedron"
	Part.Anchored=true
	Part.Position=Vector3.new(0,10,0)
	Part.Size=Vector3.new(4,4,4)

	local EditableMesh = Instance.new("EditableMesh")
	for i=1,#icosahedronVerts do
		EditableMesh:AddVertex(icosahedronVerts[i])
	end
	for i=1,#icosahedronTris do
		EditableMesh:AddTriangle(icosahedronTris[i][1],icosahedronTris[i][2],icosahedronTris[i][3])
	end
	EditableMesh.Parent=Part
	return Part,EditableMesh
end
Generate()

Looks good, but some of the code can be done outside the function like t and the tables of verts and tris

Thanks alot, I will edit this post to add your changes. I appreciate your feedback.

Maybe one day someone will actually make a “one script game”
Where all meshes textures sound effects and animations are also generated

this would be a bit dumb, but also impressive, a single script builds the entire game lol.
