Basically I am trying to redo from scratch the wall building system from Bloxburg.
As currently I have been able to align it by 2 vector points (2 Cylinder parts) however They do not rotate correctly.
I have tried using the triangle cosine formula for getting the angle between the 2 sides however I was not really able to do it correct so could somebody please help me with this problem?
Function:
function WallPlacement()
local ItemForDisplay = game.ReplicatedStorage.Objects.WallCylinder:Clone()
ItemForDisplay.PrimaryPart.Orientation = Vector3.new(0,0,90)
local PreviousCylinder:Instance = nil
local CurrentBlock = nil
ItemForDisplay.Parent = workspace.Temp
Mouse.TargetFilter = ItemForDisplay
local conn1 = Mouse.Move:Connect(function()
ItemForDisplay:SetPrimaryPartCFrame(CFrame.new(Vector3.new(math.ceil(Mouse.Hit.Position.X), Mouse.Hit.Position.Y, math.ceil(Mouse.Hit.Position.Z))) * CFrame.Angles(0,0,math.rad(-90)))
if Mouse.Target.Name == 'Baseplate' then
ItemForDisplay.Fake.Color = Color3.fromRGB(0,255,0)
else
ItemForDisplay.Fake.Color = Color3.fromRGB(250,0,0)
end
end)
local conn2 = Mouse.Idle:Connect(function()
ItemForDisplay:SetPrimaryPartCFrame(CFrame.new(Vector3.new(math.ceil(Mouse.Hit.Position.X), Mouse.Hit.Position.Y, math.ceil(Mouse.Hit.Position.Z))) * CFrame.Angles(0,0,math.rad(-90)))
if Mouse.Target.Name == 'Baseplate' then
ItemForDisplay.Fake.Color = Color3.fromRGB(0,255,0)
else
ItemForDisplay.Fake.Color = Color3.fromRGB(250,0,0)
end
if Mouse.Target.Name == "Baseplate" and PreviousCylinder then
local cframe = PreviousCylinder:GetPrimaryPartCFrame():Lerp(ItemForDisplay:GetPrimaryPartCFrame(), 0.5)
local size = Vector3.new(0.5, 8.5, (Vector3.new(0,0,PreviousCylinder:GetPrimaryPartCFrame().Position.Z) - Vector3.new(0,0,ItemForDisplay:GetPrimaryPartCFrame().Position.Z)).Magnitude)
if not CurrentBlock then
CurrentBlock = Instance.new("Part", workspace.Temp)
CurrentBlock.Anchored = true
CurrentBlock.CanCollide = false
Mouse.TargetFilter = CurrentBlock
else
local b = (Vector3.new(0,0,PreviousCylinder:GetPrimaryPartCFrame().Position.X) - Vector3.new(0,0,ItemForDisplay:GetPrimaryPartCFrame().Position.X)).Magnitude
local a = (Vector3.new(0,0,PreviousCylinder:GetPrimaryPartCFrame().Position.Z) - Vector3.new(0,0,ItemForDisplay:GetPrimaryPartCFrame().Position.Z)).Magnitude
local c = math.sqrt(a^2 + b^2)
print(a)
print(b)
print(c)
local fulldegrees = math.acos(vectorA:Dot(vectorB) / (vectorA.Magnitude * vectorB.Magnitude))
print(fulldegrees)
local rotationCFrame = ItemForDisplay:GetPrimaryPartCFrame():ToObjectSpace(PreviousCylinder:GetPrimaryPartCFrame())
CurrentBlock.CFrame = cframe
CurrentBlock.Orientation = rotationCFrame.Position
CurrentBlock.Size = size
end
end
end)
local conn3 = Mouse.Button1Down:Connect(function()
if PreviousCylinder then
CloseConnections()
ItemForDisplay:Destroy()
PreviousCylinder:Destroy()
else
PreviousCylinder = ItemForDisplay
ItemForDisplay = game.ReplicatedStorage.Objects.WallCylinder:Clone()
ItemForDisplay.Parent = workspace.Temp
end
end)
table.insert(Connections, conn1)
table.insert(Connections, conn2)
table.insert(Connections, conn3)
end
Basically my problem is getting and applying the degrees. Variable: fulldegrees
The current formula is just from another article however no luck in working properly ofc.
The Resizing and Positioning works properly.
