Collision detection problem

Help and Feedback Scripting Support
#1

I have a punching animation that, upon the character’s arm colliding into another character, knocks the character back. However, even when the character’s arm collides into another character, an npc or even anything, the script does not detect it. Why does this happen?

Local script:

punchanim:GetMarkerReachedSignal("Punch"):Connect(function(param)
	inputevent:FireServer("Click", param)
end)

Server script:

inputevent.OnServerEvent:Connect(function(plr, key, arg1, arg2)
   local char = plr.Character
   if key == "Click" then
      if arg1 == "true" then
         local rightarm = char:WatForChild("Right Arm")
         punch = rightarm.Touched:Connect(function()
            --Knocking back enemy
         end
      else
         punch:Disconnect()
      end
   end
end

Instead of Touched Events, make a part in front of the player and use that as the hit box and use PartBoundsInBox for hitboxes, its just a faster and more reliable way.

If you still want to go your way and not use @JAcoboiskaka1121 method then you would do something like this:

inputevent.OnServerEvent:Connect(function(plr, key, arg1, arg2)
	local char = plr.Character
	if key == "Click" then
		if arg1 == "true" then
			local rightarm = char:WaitForChild("Right Arm")
			punch = rightarm.Touched:Connect(function(hit)
				if hit.Parent:FindFirstChild("Humanoid") then
					local bv = Instance.new("BodyVelocity")
					bv.Parent = hit.Parent.HumanoidRootPart
					bv.Velocity = rightarm.Parent.HumanoidRootPart.CFrame.LookVector * -20
					bv.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
					game:GetService("Debris"):AddItem(bv, 0.2)
				end
			end)
		else
			punch:Disconnect()
		end
	end
end)

I have also noticed that your code has some typos. (fixed them)

Is there a reason as to why you’re using Debris Service, instead of :Destroy()? Just asking.

Debris is better for a delayed :Destroy().
