Right now I’m trying to use an editable mesh to generate a ring as a basis for modeling a tornado.
However I’m having an issue with EditableMesh where no matter what I do my mesh doesn’t really render as the shape I provide it with, in this case it’s supposed to be a ring. The interesting thing is that that the collision system seems to handle it perfectly fine and is mostly accurate (inside collision appears to model that of a diamond shape, while the outside accurately appears to be a circle. But as seen in the gif below, the mesh is clearly showing up as a rectangular prism.
I have tried changing the order I put vertices on the list, I’ve limited the distance from the origin of local space to be within -1 to 1 (as a devforum said that having numbers above 1 can be an issue)
Heres my code that generates these shapes
@Script
--//Services//--
local AssetService: AssetService = game:GetService("AssetService")
local MeshService = require(script.Parent.MeshService)
--//End of "Services"//--
--//Misc.//--
local Object = script.Parent
--//End of "Misc."//--
--//Connections//--
local Mesh: MeshService.CMesh = MeshService.new_ring()
Mesh:generate(workspace)
Mesh.Object.Anchored = true
Mesh.Object.Position = Vector3.new(0, 5, 0)
--//End of "Connections"//--
This is referencing a modulescript I made which references three methods, here are those three methods.
@MeshService
local function GenerateRing(Mesh: CMesh, Resolution: number): ()
local MeshData = Mesh.MeshData
for i = 0,Resolution - 1 do
local v1 = i * 2 * math.pi / Resolution
local v2 = (i+1) * 2 * math.pi / Resolution
local Z1, X1, Z2, X2 = math.sin(v1), math.cos(v1), math.sin(v2), math.cos(v2)
local Vertex1 = MeshData:AddVertex(Vector3.new(X1, 1, Z1))
local Vertex2 = MeshData:AddVertex(Vector3.new(X2, 1, Z2))
local Vertex3 = MeshData:AddVertex(Vector3.new(X2, -1, Z2))
local Vertex4 = MeshData:AddVertex(Vector3.new(X1, -1, Z1))
local Triangle1 = MeshData:AddTriangle(Vertex1, Vertex2, Vertex3)
local Triangle2 = MeshData:AddTriangle(Vertex1, Vertex4, Vertex3)
end
MeshData:RemoveUnused()
end
function Service.new_ring(): CMesh
local Mesh = Service.new()
GenerateRing(Mesh, 500)
return Mesh
end
function Service.new(): CMesh
local Data: EditableMesh = AssetService:CreateEditableMesh()
local Mesh: CMesh_fluid = {
MeshData = Data
}
--/generate_macro!
function Mesh:generate(Parent: Instance?): ()
Service.generate(self, Parent)
end
--/transform_macro!
function Mesh:transform_vertices(Transformer: CMesh_transform_vertex): ()
Service.transform_vertices(self, Transformer)
end
--/ Solidfy and Return CMesh.
return Mesh :: CMesh
end
Here are the custom types I use
export type CMesh_transform_vertex = (vertexId: number, vertexPos: Vector3) -> Vector3
export type CMesh_mut_func = (...any) -> ()
export type CMesh_fluid = {
--/ Fields
MeshData: EditableMesh,
Object: MeshPart?,
--/ Methods
generate: CMesh_mut_func?,
transform_vertices: CMesh_mut_func?,
}
export type CMesh = {
--/ Fields
MeshData: EditableMesh,
Object: MeshPart?,
--/ Methods
generate: CMesh_mut_func,
transform_vertices: CMesh_mut_func,
}
Any ideas where/what I am doing wrong?
