Added Reach Detection! (I forgot to post this when i added it lol, it was added a week ago) → Give me more suggestions of what to add.

This reach detection is not reliable - it’s not accurate enough and so is likely to cause false positives when the size of the player’s actual sword handle is much bigger. Even though a simple fix is just to compare the distance of handle and the enemy and see if it’s high enough, however the best solution is to use WorldRoot:GetPartsInParts and check if the handle of the sword is touching any base part of the enemy’s character.

local Players = game:GetService("Players")

handle.Touched:Connect(function(hit)
   local enemyCharacter = Players:GetPlayerFromCharacter(hit.Parent)

   if not enemyCharacter then return end

   local enemyHumanoid = enemyCharacter:FindFirstChildWhichIsA("Humanoid")

   if not enemyHumanoid then return end

   local handleOverlapParams = OverlapParams.new()
   handleOverlapParams.FilterDescendantsInstances = {enemyCharacter} 
   handleOverlapParams.FilterType = Enum.RaycastFilterType.Whitelist

    -- Make sure that the handle is AT-LEAST touching any part of the enemy's 
    -- character before we do damage:
    if #workspace:GetPartsInPart(Handle, handleOverlapParams) == 0 then return end

    enemyHumanoid:TakeDamage(15) 
end

Problems with this approach

  • If a player is having a poor frame rate, then the player’s hits will not likely be registered on the server, since the replication frequency of the player’s position to the server will be slowed down.

  • Again, if a player is experiencing high latency, the same problem mentioned above will be faced.

  • Even if both the cases are not a problem, if the player is moving their melee weapon very fast or them selves are moving very fast, then again their hits will not be registered. This is because of the replication hertz at which position and other data is sent to the server from the client (assuming the player has network ownership of their melee weapon and themselves), i.e the player’s approximate frame rate, since most replication data is usually sent every frame.

  • Exploiters can quickly move themselves to the opponent and then kill them, bypassing this check mostly, except in some cases where they move extremely fast enough to the extent their new position has not yet replicated to the server. You may develop an anti exploit to counter this, but other cases include them moving quickly to their opponent, but just not at a very high speed. Thus, mostly bypassing the anti exploit it self! You cannot handle this your self reliably…

  • You may try to account for most of these problems by either increasing the size of the hitbox based off of the player’s ping (player:GetNetworkPing), but again this isn’t reliable since the difference between the client’s data and the server’s data will be very different and far from being at least “closely” synced.

Exploiters are able to trigger .touched events on other players

This was just an example; not something too advanced.

Right, but it is never bad to give advice!

Oh lol, but is there any way to disable console log in Roblox server, so no one can inject
