I’ve used to have my enemies system simply use the MoveTo function on the humanoid but after some testing I realized the game gets quite a high Recv when alot of enemies are spawned in so after some looking around I came across this post which seems to have solved the issue, I’m trying to use the code provided in it but instead this happens:
Not only that I don’t know what seems to be the issue, this has a lot of complications for example when stunning the enemy how would that work?
here’s the client code I used:
--- Some client stuff
local Precision = 10^2
local tableOfPaths = game.ReplicatedStorage.RequestPaths:InvokeServer()
local tableOfEnemies = {}
function Decompile(EnemyData)
return {
["EnemyId"] = EnemyData[1],
["EnemyPosition"] = EnemyData[2],
["EnemyRotation"] = EnemyData[3],
["Node"] = EnemyData[4],
["Speed"] = EnemyData[5],
["Path"] = tableOfPaths[EnemyData[6]],
["SyncTime"] = workspace.DistributedGameTime - EnemyData[7],
["Done"] = false,
}
end
game.ReplicatedStorage.SpawnedEnemy.OnClientEvent:Connect(function(EnemyInfo)
local ClientTableEnemyInfo = Decompile(EnemyInfo)
local key = ClientTableEnemyInfo["EnemyId"]
tableOfEnemies[key] = ClientTableEnemyInfo
local Precision = 10^2
local CFrameNoOrientation = CFrame.new(ClientTableEnemyInfo["EnemyPosition"].X / Precision, ClientTableEnemyInfo["EnemyPosition"].Y / Precision, ClientTableEnemyInfo["EnemyPosition"].Z / Precision)
local CFrameWithOrientation = CFrameNoOrientation * CFrame.Angles(0, ClientTableEnemyInfo["EnemyRotation"].Y / Precision, 0)
local cloneClientSide = game.ReplicatedStorage.Enemies.Models.Test:Clone()
cloneClientSide.Name = ClientTableEnemyInfo["EnemyId"]
cloneClientSide.Parent = game.Workspace.Enemies
cloneClientSide:PivotTo(CFrameWithOrientation)
end)
function HandleMovement()
for i,Enemy in pairs(tableOfEnemies) do
local clientTarget = game.Workspace.Enemies[Enemy["EnemyId"]]
if Enemy.Done then
tableOfEnemies[i] = nil
game.Debris:AddItem(clientTarget, 0)
else
clientTarget.CFrame = clientTarget.CFrame:ToWorldSpace(CFrame.new(0, 0, -0.1 * Enemy.Speed))
local magnitude = (clientTarget.CFrame.Position - Enemy.Path[Enemy.Node + 1].Position).Magnitude
if magnitude <= 1 then
Enemy.Node += 1
if Enemy.Node == #Enemy.Path then
Enemy.Done = true
else
if Enemy.SyncTime then
clientTarget.CFrame = CFrame.new(Enemy.Path[Enemy.Node].Position, Enemy.Path[Enemy.Node + 1].Position + (Enemy.Path[Enemy.Node + 1].Position * Enemy.SyncTime))
Enemy.SyncTime = nil
else
clientTarget.CFrame = CFrame.new(Enemy.Path[Enemy.Node].Position, Enemy.Path[Enemy.Node + 1].Position)
end
end
end
end
end
end
while true do
task.wait(0.01)
HandleMovement()
end
and this is the server code:
local SpawnedEnemy = game.ReplicatedStorage:WaitForChild("SpawnedEnemy")
