Applying images to a surface, rotation and different surfaces?
Brief: We click on an object's front surface, and it applies a ImageLabel centered around the mouse. The size is constant on all different sizes.
Problem 2: I can't apply this to all surfaces, I've already got the Surface's Normal being returned, but from there on, I don't know how to apply this information.
Here is me code:
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local Texture = "http://www.roblox.com/asset/?id=82021756"
local Sizer = 20
function Positioning(part,hitpos)
local PixelRef = part.CFrame:toObjectSpace(CFrame.new(hitpos))--*CFrame.new(-part.Size.X/2,-part.Size.Y/2,0)
local XRef = -PixelRef.p.X-- -math.ceil(PixelRef.X) If we want this to be applied on a stud=pixel scale (Messes up positions)
local YRef = -PixelRef.p.Y-- -math.ceil(PixelRef.Y)
return XRef,YRef
end
function click()
local target = mouse.Target
if target then
local mRay = mouse.UnitRay
local ray = Ray.new( mRay.Origin, mRay.Direction * 100 )
local part, pos, normal = game.Workspace:FindPartOnRay( ray, player.Character )
if part then
print(part.Name,pos,normal)
local surface
local frame
if part:findFirstChild("SurfaceGui") then
surface = part:findFirstChild("SurfaceGui")
frame = surface.Framey
else
print("Found none")
surface = Instance.new( "SurfaceGui", part)
surface.CanvasSize = Vector2.new(part.Size.X*10,part.Size.Y*10)
frame = Instance.new("Frame", surface)
frame.Name = "Framey"
frame.Size = UDim2.new(1,0,1,0)
frame.ClipsDescendants = true
frame.BackgroundTransparency =1
end
local Tex = Instance.new("ImageLabel",frame)
Tex.Image = Texture
Tex.Size = UDim2.new(0,Sizer,0,Sizer)
Tex.BackgroundTransparency = 1
local X,Y = Positioning(part,pos)
print(X,Y)
Tex.Position = UDim2.new(.5+(X/(part.Size.X)),-Sizer/2,.5+(Y/(part.Size.Y)),-Sizer/2)
end
end
end
mouse.Button1Down:connect(click)
I've figured out where I was going wrong with the application, but I don't understand how I need to edit this to apply to other surfaces.

Kept running into problems, but this one works, all Parts (Including wedges and corners, however it will only work on the FLAT parts of this surface, it does not produce a Face value for the slopes)
Hopefully I'll be able to add more things to this, such as removing overlapping pictures and converting them into one big image, similairly, this would be cool for growing puddles. This would look really cool for explosions
I'm also fairly interested in getting these to wrap around corners, or be spread over multiple moving bricks (pretty sure there was a Snack Break problem about this).
In the meantime however, feel free to use the code. First applications I can think of are bullet holes and splats, but I'm sure someone can think of some more interesting applications. Here ya go!
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local Texture = "http://www.roblox.com/asset/?id=82021756"--<Your image or whatever
local PicSize = 20 --How many "pixels" the image is (Always square shape)
local CanSize = 10 --10 pixels offset, unless replacing the Picture for something made of frames, not necessary to change
function Positioning(part,hitpos)
local PixelRef
return -PixelRef.p
end
function ReturnNormal(PartCF,RayNorm)
if PartCF.lookVector - RayNorm == Vector3.new(0,0,0) then
return "Front",5
elseif PartCF.lookVector + RayNorm == Vector3.new(0,0,0) then
return "Back",2
else
local x, y, z, R00, R01, R02, R10, R11, R12, R20, R21, R22 = PartCF:components()
if Vector3.new(R01,R11,R21) == RayNorm then
return"Top", 1
elseif Vector3.new(-R01,-R11,-R21) == RayNorm then
return "Bottom",4
elseif Vector3.new(-R00,-R10,-R20) == RayNorm then
return "Left",3
elseif Vector3.new(R00,R10,R20) == RayNorm then
return "Right",0
