Hello!
I’m currently trying to polish off my wall placement system but I have ran into a very specific problem that I’m not sure how to fix.
So, I want to detect the intersection’s outer walls so I know where to place an extra part so there’s no weird gap. The problem with this is that when I place a wall that’s shorter than the previous wall and at an acute angle, it seems to detect the outer wall incorrectly.
Here’s my “logic”:
-- quadrants:
-- 2 1
-- |
-- 3 4
if wall2RelativeToWall1.X > 0 then -- 1 or 4
if wall2RelativeToWall1.Z < 0 then
quadrant = 1
else
quadrant = 4
end
else -- 2 or 3
if wall2RelativeToWall1.Z < 0 then
quadrant = 2
else
quadrant = 3
end
end
local partFromWall1, partFromWall2
if quadrant == 1 then
partFromWall1 = wall1:WaitForChild('Part1')
if intersectingWallPoint2.Name == '1' then
print(1)
partFromWall2 = wall2:FindFirstChild('Part2')
elseif intersectingWallPoint2.Name == '2' then
print(2)
partFromWall2 = wall2:FindFirstChild('Part1')
end
elseif quadrant == 2 then
partFromWall1 = wall1:WaitForChild('Part2')
if intersectingWallPoint2.Name == '1' then
print(1)
partFromWall2 = wall2:FindFirstChild('Part1')
elseif intersectingWallPoint2.Name == '2' then
print(2)
partFromWall2 = wall2:FindFirstChild('Part2')
end
elseif quadrant == 3 then
partFromWall1 = wall1:WaitForChild('Part2')
if intersectingWallPoint2.Name == '1' then
print(1)
partFromWall2 = wall2:FindFirstChild('Part2')
elseif intersectingWallPoint2.Name == '2' then
print(2)
partFromWall2 = wall2:FindFirstChild('Part1')
end
elseif quadrant == 4 then
partFromWall1 = wall1:WaitForChild('Part1')
if intersectingWallPoint2.Name == '1' then
print(1)
partFromWall2 = wall2:FindFirstChild('Part1')
elseif intersectingWallPoint2.Name == '2' then
print(2)
partFromWall2 = wall2:FindFirstChild('Part2')
end
end
makeTestPart(partFromWall1.Position, Color3.new(1,0,0))
makeTestPart(partFromWall2.Position, Color3.new(0,1,0))
print(quadrant, partFromWall1, partFromWall2)
The issue happens only when the second wall is shorter than the first, not if the first wall is shorter than the second, and only if it’s at an acute angle.
As you can see here, red (placed first) has the dot on the right side whereas the green dot (indicating second placement) is placed incorrectly, on the wrong side of the wall.
On my other attempts where this really specific things isn’t happening, the dots are placed correctly.
I’m considering switching to another method because this is a dealbreaker for me, if nobody can offer a solution that is.
TIA for any help!
