How do I make it so it detects when players are touched during a animation?

I have a script where the arm gets launched at a player using a animation. The problem is the touched events don't work unless the players turn. Is there any way to fix this?

totool = script.Parent
cooldown = false
character = game.Players.LocalPlayer.Character
player = game.Players.LocalPlayer



local function weldBetween(a, b)
    --Make a new Weld and Parent it to a.
    local weld = Instance.new("ManualWeld", a)
    weld.Part0 = a
    weld.Part1 = b
    --Get the CFrame of b relative to a.
    weld.C0 = a.CFrame:inverse() * b.CFrame
    --Return the reference to the weld so that you can change it later.
    return weld
end


tool.Activated:connect(function()
	if cooldown == false then
		
		rightArm = character["Right Arm"]:Clone()
		rightArm.Name = "CRight Arm"
		rightArm.Parent = character
		
		
		x = game.Lighting.AnimationFixScript2:Clone()
		x.Parent = rightArm
		
		weldBetween(rightArm,character["Right Arm"])
		cooldown = true
		game.Chat:Chat(player.Character.Head, "Chop Chop Punch!")
		Animation = tool.Animation
		AnimationTrak = tool.Parent.Humanoid:LoadAnimation(Animation)
		AnimationTrak:Play()
		candamage = true
		rightArm.touched:connect(function(Target)
			if candamage == true then
	
				if Target.Parent.Name ~= character.Name and candamage == true then
							
					candamage = false
					Target.Parent.Humanoid.Health = Target.Parent.Humanoid.Health - 20
					candamage = false
					wait(2)
				end
			end

		end)
			wait(5)
			cooldown = false
	end
end)

What are you trying to do with the rightarm.touched?'

rightArm.touched:connect(function(Target) --This is the part of the code that is probably causing it
            if candamage == true then
                if Target.Parent.Name ~= character.Name and candamage == true then
                    candamage = false
                    Target.Parent.Humanoid.Health = Target.Parent.Humanoid.Health - 20
                    candamage = false
                    wait(2)
                end
            end
        end)

What you did is create a script where it damages the player only if it hit his/her right arm. I think that might be your problem. Try changing it so something like,

torso.touched:connect(function(Target) --This is the part of the code that is probably causing it
            if candamage == true then
                if Target.Parent.Name ~= character.Name and candamage == true then
                    candamage = false
                    Target.Parent.Humanoid.Health = Target.Parent.Humanoid.Health - 20
                    candamage = false
                    wait(2)
                end
            end
        end)

This would activate if you hit their torso. Try to make a .hit statement and create an if statement to check to see if the parent of the part that was hit was the player (and obviously not the right arm).
