I played a game the other day that had the premise of the LIDAR map from Garry’s Mod and enjoyed the concept, so I thought I’d recreate it myself and maybe put a spin on it. Currently I have the basic system down of raycasting and then placing dots where the rays hit, but when the camera looks straight up or straight down the dots seem to “compress” and the cone gets tighter. Truthfully I don’t fully understand the CFrame math that’s happening and just kinda brute forced it until it worked, so any help would be appreciated.
This is how it’s supposed to look:
This is when the camera is straight up:
This is when the camera is straight down:
And this is the code:
uis.InputBegan:Connect(function(input, gpe)
if gpe then
return
else
if input.KeyCode == Enum.KeyCode.F and debounce == false then
debounce = true
workspace.CurrentCamera.CameraType = Enum.CameraType.Scriptable
hum.WalkSpeed = 0
for y = 40, -40, -2 do
local camera = workspace.CurrentCamera.CFrame
for x = 80, -80, -2 do
local ranX = math.random(x-1, x)
local ranY = math.random(y-1, y)
local rayresult = workspace:Raycast(camera.Position, (camera.LookVector * 100) + Vector3.new(camera.RightVector.X * -ranX,ranY,camera.ZVector.X * ranX),params)
-- negative rightvector + position zvector makes it go left
-- positive rightvector + negative zvector makes it go right
if rayresult then
local newdot = dot:Clone()
newdot.Position = rayresult.Position
newdot.Parent = workspace.dotholder
local otherdots = workspace:GetPartsInPart(newdot)
if #otherdots > 1 then
destroydots(otherdots, newdot)
else
table.insert(ignorelist, dot)
task.delay(45, newdot.Destroy, newdot)
end
end
end
runservice.Heartbeat:Wait(0.5)
end
workspace.CurrentCamera.CameraType = Enum.CameraType.Custom
hum.WalkSpeed = 16
debounce = false
end
end
end)
Extra info:
- newdot is being cloned from ReplicatedStorage
- destroydots is a function to make sure the dots don’t overlap, it saves performance since they’re already pretty close together
- Everything in the character is blacklisted so the rays pass through them
