Hey!
-
What do you want to achieve? I want to make a custom shadow system, specifically a recreation of the old Stencil shadows which were removed in 2014.
-
What is the issue? I cannot figure out how to get the shadow to be filled in, and I have no clue how I’m gonna start with Meshes, Cylinders and Spheres.
-
What solutions have you tried so far? I tried winging it, using a basic diagram as my outline, but I soon got stuck on stuff I shouldn’t have.
This is the module I have for this:
local shadow = {}
function shadow.GetVertices(part : BasePart)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice1"
at.Position = Vector3.new(part.Size.X/2,part.Size.Y/2,part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice2"
at.Position = Vector3.new(-part.Size.X/2,part.Size.Y/2,part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice3"
at.Position = Vector3.new(-part.Size.X/2,-part.Size.Y/2,-part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice4"
at.Position = Vector3.new(-part.Size.X/2,-part.Size.Y/2,part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice5"
at.Position = Vector3.new(-part.Size.X/2,part.Size.Y/2,-part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice6"
at.Position = Vector3.new(part.Size.X/2,part.Size.Y/2,-part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice7"
at.Position = Vector3.new(part.Size.X/2,-part.Size.Y/2,part.Size.Z/2)
local at = Instance.new("Attachment")
at.Parent = part
at.Name = "Vertice8"
at.Position = Vector3.new(part.Size.X/2,-part.Size.Y/2,-part.Size.Z/2)
end

function shadow.TriangleSurfaceGuiThingy(t1,t2,t3,canvas,face)
local sg = Instance.new("SurfaceGui")
sg.Parent = workspace.Shadows
sg.Name = "RWBX_Shadow"
sg.Face = face
sg.SizingMode = Enum.SurfaceGuiSizingMode.PixelsPerStud
sg.PixelsPerStud = 50
sg.Adornee = canvas
local img = Instance.new("ImageLabel")
img.Parent = sg

img.Image = "rbxassetid://73331143039375"
img.ImageTransparency = 0.8
img.BackgroundTransparency = 1
img.AnchorPoint = Vector2.new(0,1)
img.Size = UDim2.new(0,(t1 - t2).Magnitude*50,0,(t1 - t3).Magnitude*50)
img.Rotation = 270
img.Position = UDim2.new(0.5,-t1.Z * 50+canvas.Position.Z - 150,0.5,t1.X * 50+canvas.Position.X - 50)
end
function shadow.GetShadowCorners(corner : Attachment)
local direction = (game:GetService("Lighting"):GetSunDirection() * Vector3.new(10,10,10))
local rayStartingPoint = corner.WorldPosition + direction
local rayLookAt = CFrame.new(rayStartingPoint,corner.WorldPosition)
local rayParams = RaycastParams.new()
rayParams.FilterType = Enum.RaycastFilterType.Exclude
rayParams.FilterDescendantsInstances = {corner.Parent}
local ray = workspace:Raycast(rayStartingPoint,rayLookAt.LookVector * 5000000,rayParams)
local part = Instance.new("Part",workspace.Parts)
part.Size = Vector3.new(.1,.1,.1)
part.Position = ray.Position
part.Anchored = true
end
function shadow.Refresh(part)
for i,e in pairs(workspace.Parts:GetChildren()) do
e:Destroy()
end
for i,e in pairs(part:GetChildren()) do
e:Destroy()
end
shadow.GetVertices(part)
for i,e in pairs(part:GetChildren()) do
shadow.GetShadowCorners(e)
end
end
return shadow
I would deeply appreciate any help I can get on this, because I’ve been wanting to get these style of shadows for at least a few months now.
Thanks in advance! (and of course, if you need any more information I will gladly send it)
