hey so when my police man npc kills another npc it says attempt to index nil with findfirstchild, and i want to fix that
so ive tried to look at the arguments that my functions in my module script needs
and it seems that everything is filled out so idk whats happening.
heres my module and server script:
local policemodule = {}
function wander(hum, root, character)
local area = Vector3.new(root.Position.X + math.random(-30, 30), 0, root.Position.Z + math.random(-30, 30))
local pathfinding = game:GetService("PathfindingService")
local path = pathfinding:CreatePath({
AgentCanJump = true,
AgentCanClimb = true
})
path:ComputeAsync(root.Position, area)
for i, waypoint in pairs(path:GetWaypoints()) do
local waypoints = path:GetWaypoints()
if waypoint.Action == Enum.PathWaypointAction.Jump then
hum.Jump = true
end
hum:MoveTo(waypoint.Position)
local timeout = hum.MoveToFinished:Wait(1)
local nearest = findnearest(root)
if raycastsight(nearest, character) then
policemodule.walktotarget(root, hum, character)
break
end
if not timeout then
hum.Jump = true
wander(hum, root, character)
break
end
end
end
function findnearest(root)
local maxdist = 300
local nearest = nil
for i, v in pairs(workspace:GetChildren()) do
local vhum = v:FindFirstChild("Humanoid")
local vroot = v:FindFirstChild("HumanoidRootPart")
local status = v:FindFirstChild("Type")
if vhum and vroot and status.Value == "Criminal" and vhum.Health > 0 then
if nearest == nil then
nearest = vroot
end
if (root.Position - vroot.Position).magnitude <= maxdist then
maxdist = (root.Position - vroot.Position).magnitude
nearest = vroot
end
end
end
return nearest
end
function policemodule.walktotarget(root, hum, character)
local nearesttarget = findnearest(root)

if u need anything ask me
