Hello I am making a fps game and want to make a gun npc but i can figure out how to raycast more than just forward. I want the npc to see in all directions. Any help?
while wait() do
local ray = Ray.new(origin.Position, origin.CFrame.lookVector * DISTANCE) -- Calculating the raycast.
local hit = workspace:FindPartOnRay(ray, origin.Parent) -- Creating a ray to see what the npc sees.
if hit then
for _, player in pairs(Players:GetPlayers()) do -- We're going to loop through all players to see if the npc sees any of them.
if player.Character and player.Character:IsAncestorOf(hit) then
-- Handle what happens here.
print("I see " .. player.Name)
break
end
end
end
end
You cannot fire one single raycast in multiple directions. Instead, fire one for each player.
Loop through all players, fire a raycast to each single player using their HumanoidRootParts position as a target.
Blacklist the targeted players character for each ray.
If your raycast DID hit something, it means something is in the way.
If it did NOT hit something, you’ve got your player in sight.
Do keep the following things in mind though:
-Not hitting something can also mean that the raycast reached its maximum distance
-If you only blacklist the targeted player for each ray, then players can block the view to other players by standing in front of your NPCs
-Firing just one ray per player, and using their HumanoidRootParts position as a target, means that if they only show their arm behind a wall for example, the NPC will not see them
while task.wait() do
for _, player: Player in ipairs(Players:GetPlayers()) do -- We're going to loop through all players to see if the npc sees any of them.
local character: Model = player.Character
if character then
local HumanoidRootPart: BasePart = character:FindFirstChild("HumanoidRootPart")
if HumanoidRootPart then
local rayParams: RaycastParams = RaycastParams.new()
local result = workspace:Raycast(origin.Position, CFrame.lookAt(origin, HumanoidRootPart.Position).LookVector * DISTANCE, rayParams)
--result will return the part that is hit, otherwise nil
if result and result.Instance:IsDescendantOf(character) then
-- Handle what happens here.
print("I see " .. player.Name)
break
end
end
end
end
end
local arcAngle = 90
local distance = 10
while task.wait() do
for a=0, arcAngle, 1 do
local angle = a-(arcAngle/2)
local dir = Vector3.new(
math.cos(math.rad(angle)),
0,
math.sin(math.rad(angle))
)
local params = RaycastParams.new() --dunno what should be here, figure it out
local ray = workspace:Raycast(orgin.Position, dir*distance, params)
if not ray then continue end
if not ray.Instance.Parent:FindFirstChild("Humanoid") then return end
print("I see player")
end
end
