I’m trying to make a floor placement system similar to ‘Welcome to Bloxburg’ and ‘Restaurant Tycoon 2’ where the player would place down points on the ground and the system would construct a floor shaped from those points placed down by the player.
The problem I’m currently face right now is figuring out how to make the system work well with forming concave shapes.
Here is what I have made so far.
As you can see, it doesn’t do a good job whenever I try to form a concave shape.
here is the code for whenever the player presses the mouse button to place down a point on the ground.
local newnode = TempNode:Clone()
newnode.Parent = workspace
Index = Index + 1
print(Index)
newnode.Name = Index
table.insert(Nodes, newnode)
for _,v in Tri do
v:Destroy()
end
Tri = {}
for i = 1, #Nodes - 1 do
local startPos = Nodes[i].Position
local endPos = Nodes[i + 1].Position
local line = Instance.new("Part")
line.Size = Vector3.new(0.2, 0.2, (endPos - startPos).Magnitude)
line.CFrame = CFrame.new(startPos, endPos) * CFrame.new(0, 0, -line.Size.Z / 2)
line.Anchored = true
line.Parent = workspace
table.insert(Lines,line)
end
if #Nodes > 2 then
for i,v in Nodes do
if (i % 2) == 0 then
if #Nodes == i then
if i >= 6 then
local ta,tb
local a = Nodes[5]
local b = Nodes[3]
local c = Nodes[1]
ta, tb = Triangle(a.Position, b.Position, c.Position, workspace, ta, tb)
table.insert(Tri,ta)
table.insert(Tri,tb)
end
local ta,tb
local a = Nodes[i-1]
local b = Nodes[i]
local c = Nodes[1]
ta, tb = Triangle(a.Position, b.Position, c.Position, workspace, ta, tb)
table.insert(Tri,ta)
table.insert(Tri,tb)
elseif #Nodes - 1 == i then
local ta,tb
local a = Nodes[i-1]
local b = Nodes[i]
local c = Nodes[1]
ta, tb = Triangle(a.Position, b.Position, c.Position, workspace, ta, tb)
table.insert(Tri,ta)
table.insert(Tri,tb)
else
local ta,tb
local a = Nodes[i-1]
local b = Nodes[i]
local c = Nodes[i+1]
ta, tb = Triangle(a.Position, b.Position, c.Position, workspace, ta, tb)
table.insert(Tri,ta)
table.insert(Tri,tb)
end
else
if #Nodes == i then
local ta,tb
local a = Nodes[i-1]
local b = Nodes[i]
local c = Nodes[1]
ta, tb = Triangle(a.Position, b.Position, c.Position, workspace, ta, tb)
table.insert(Tri,ta)
table.insert(Tri,tb)
elseif i >= 5 then
local ta,tb
local a = Nodes[i]
local b = Nodes[i-2]
local c = Nodes[1]
ta, tb = Triangle(a.Position, b.Position, c.Position, workspace, ta, tb)
table.insert(Tri,ta)
table.insert(Tri,tb)
end
end
end
for i,v in Tri do
v.Transparency = 0.8
end
end
I would appreciate it if someone would help me with coming up with a better approach so that my system would work well with forming concave shapes.
