What do you want to achieve? Keep it simple and clear!
Im trying to get the turret model i made, to detect players in a angle in front of it, while i also want it to change later on when i add “upgrades” that increase that angle
What is the issue? Include screenshots / videos if possible!
i dont know how exactly to do that, i got some code working but it detect a full 360 angle
wait()
local gun = script.Parent:WaitForChild("Gun")
local Main = script.Parent:WaitForChild("Main2")
--Angle = 0
function getRoots()
local roots = {}
for _,player in pairs(game.Players:GetChildren()) do
--print(player)
if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
table.insert(roots,player.Character.HumanoidRootPart)
--print(player)
end
end
return roots
end
position = Main.Position
radius = 30
overlapParams = OverlapParams.new()
overlapParams.FilterType = Enum.RaycastFilterType.Include
overlapParams.FilterDescendantsInstances = getRoots()
--[[
--shooting animation
local rotatedCFrame = CFrame.Angles(0, 0, math.rad(17))--math.rad(20))
gun.CFrame = gun.CFrame:ToWorldSpace(rotatedCFrame)
]]
rayP = RaycastParams.new()
rayP.FilterType = Enum.RaycastFilterType.Exclude
rayP.FilterDescendantsInstances = {script.Parent,workspace.Baseplate}
local p1 = workspace:WaitForChild("p1")
local p2 = workspace:WaitForChild("p2")
while wait() do
roots = getRoots()
overlapParams.FilterDescendantsInstances = getRoots()
nearbyPlayers = workspace:GetPartBoundsInRadius(position, radius, overlapParams)
-- ^ right here, it gets a 360 area with a radius of 30
for i,v in pairs(nearbyPlayers) do
local direction = (Main.Position - v.Position)*-1
p1.Position = Main.Position
p2.Position = (Main.Position + direction)
--print(direction)
raycast = workspace:Raycast(Main.Position, direction,rayP)
if raycast.Instance ~= nil then
print(raycast.Instance)
end
end
--print(nearbyPlayers[1])
--print(gun.Rotation)
end
i thought of making another ray that detect invisible barriers and then put the turret in a “box” , when the ray detects that box it shouldnt shoot but i dont think thats really practical
i also thought of using a invisible cone shape and detect when a player enters it, but it might cause a lot of trouble later
it just feels like im missing something, i just dont know what it is
Add this script inside your loop. It will detect the front so it won’t work if you try to detect from other rotation like the right or the back.
local hrp = character.HumanoidRootPart -- suposing you are detecting from here
local object -- object that you want to check if its inside the cone
local radius = 5
local angle = 45 -- to "upgrade" increase this number
if (hrp.Position - obj.Position).Magnitude <= radius then
local dot = hrp.Position:Dot(object.Position)
if dot >= 0 and dot <= math.cos(math.rad(angle)) then
-- inside the cone
end
end
well like if you’re just tryna get the people within a fov boy do i have code for you (credit to sleitnick)
local function AngleBetween(VectorA, VectorB)
return math.acos(math.clamp(VectorA:Dot(VectorB), -1, 1))
end
local function IsDotProductWithin(CFrameA, CFrameB, FOV)
local FovCheck = math.rad(FOV) / 2
local LookForward = CFrameA.LookVector
local LookToPoint = (CFrameB.Position - CFrameA.Position).Unit
local Angle = AngleBetween(LookForward, LookToPoint)
return math.abs(Angle) <= FovCheck
end
basically do IsDotProductWithin(Turret.CFrame, Target.CFrame, 90) – set 90 the fov u want
and then raycast to the player’s position if they are within the fov
it didnt seem to work, i used print(“test”) and print(“inside cone”) to see where it was not working and it seems it wont activate this:
if dot >= 0 and dot <= math.cos(math.rad(angle)) then
for i,v in pairs(nearbyPlayers) do
local direction = (Main.Position - v.Position)*-1
p1.Position = Main.Position
p2.Position = (Main.Position + direction)
----------------------------------------------------------------------
local obj1 = v -- suposing you are detecting from here
local obj2 = Main -- object that you want to check if its inside the cone
local radius = 30
local angle = 45 -- to "upgrade" increase this number
if (obj1.Position - obj2.Position).Magnitude <= radius then
print("test")
local dot = obj1.Position:Dot(obj2.Position)
print(dot)
if dot >= 0 and dot <= math.cos(math.rad(angle)) then
-- inside the cone
print("INSIDE CONE")
end
end
----------------------------------------------------------------------
--print(direction)
raycast = workspace:Raycast(Main.Position, direction,rayP)
if raycast.Instance ~= nil then
--print(raycast.Instance)
end
end
edit: dot is giving me huge numbers like 1000 3000 1600 etc
