Hi devs!
Today. I was trying to make my tower find enemies from a table regarding their positions and alpha value. It works really well when there are 1 or more enemies with the same name or type. But for some reason when a enemy with a different name came into range the towers constantly switch random targets and sometimes it even stops attacking
Video showing the issue::
Here are my scripts involving targetting
Enemy
local activeCharacters = {}
function class.new(name)
local modelTemplate = game.ReplicatedStorage.Common.Server:FindFirstChild(name)
if not modelTemplate then
warn(tostring(name) .. "' does not exist in ReplicatedStorage.Characters")
return nil
end
local model = modelTemplate:Clone()
model:SetAttribute("Alpha", 0)
model:SetAttribute("Speed", model:GetAttribute("Speed") or 1)
model:SetAttribute("Health", model:GetAttribute("Health") or 100)
model.Parent = workspace.Characters
local self: Enemy = setmetatable({}, class) :: any
self.Model = model :: Model
self.CFrameIndex = 1
for _, playerObj in plr:GetPlayers() do
myPacket.SpawnEnemy:FireClient(playerObj, self.Model)
end
local rotationalOffset = Vector3.new(0, 0, math.rad(0))
local minOffset = -1.1111
local maxOffset = 1.1111
local offset = (math.random() * (maxOffset - minOffset)) + minOffset
local rotationalCFrame = CFrame.Angles(rotationalOffset.X, rotationalOffset.Y, rotationalOffset.Z)
local offsetCFrame = CFrame.new(offset, 0, 0)
if #wayPositions == 0 then
for i = 1, #workspace.Path:GetChildren() do
local waypoints = workspace.Path[i]
local adjustedPositions = waypoints.Position
table.insert(wayPositions, adjustedPositions)

self.NewPath = BezierPath.new(wayPositions, 2.5)
self.PathLength = self.NewPath:GetPathLength()
