I need help with an accurate reflection
When the reflective ray bounces off of a surface, then the next ray angles slightly downward
I have already checked that the equation was accurate, and looked over my code
I have not found any code that changes the angles purposefully
local function reflect(vector, normal)--creds egomoose for math
return -2 * vector:Dot(normal) * normal + vector;
end
function nex(frame,new,hit,pos,norm)
--print(amnt)
local calc = new
if hit then
local ref = reflect((new).Position-frame.Position,norm)
calc = CFrame.new(frame.Position)*CFrame.new(Vector3.new(0,0,0),ref)
end
return calc,pos
end
function line(a,b)
local new = Instance.new("Part")
new.Parent = script.Parent.Parent.Rays
local mag = (a-b).Magnitude
--local pos = (a*(1-0.5))+b*0.5
new.Size = Vector3.new(.1,.1,mag)
new.Anchored = true
new.CanCollide = false
new.Material = Enum.Material.Neon
new.Color = Color3.new(1,0,0)
new.CFrame = CFrame.new(a,b)*CFrame.new(0,0,-mag/2)
end
while game:GetService("RunService").Stepped:Wait() do
local all = workspace.Lazer.Rays:GetChildren()
for i = 1,#all do
all[i]:Destroy()
end
local frame = script.Parent.CFrame
for i = 1,100 do
local to = (frame*CFrame.new(0,0,-100)).Position
local vec = to-frame.Position
local ray = Ray.new(frame.Position,vec)
local hit,pos,norm = workspace:FindPartOnRayWithIgnoreList(ray,{script.Parent.Parent})
local frame2
--vec = vec/Vector3.new(math.abs(vec.X),math.abs(vec.Y),math.abs(vec.Z))
if hit then
to = pos
local ref = reflect(vec,norm)
frame2 = CFrame.new(pos,ref)
end
line(frame.Position,to)
if frame2 then
frame = frame2
else
break
end
end
end
