how do i make my weapon hurt only npcs and not players and make it work in R15?

You didn't format your code correctly but I think I can still help. Do you see this part in the script with a lot of if statements that return early if they are true?

	if not RightGrip or (RightGrip.Part0 ~= Handle and RightGrip.Part1 ~= Handle) then
		return
	end
	local character = Hit.Parent
	if character == Character then
		return
	end
	local humanoid = character:FindFirstChildOfClass("Humanoid")
	if not humanoid or humanoid.Health == 0 then
		return
	end
	local player = Players:GetPlayerFromCharacter(character)
	if player and (player == Player or IsTeamMate(Player, player)) then
		return
	end

This part of the code makes sure that the player it's about to damage isn't the player that's holding it, or a teammate, as well as some other checks. We can check if the player is any player, and cancel the damage, in this way as well.

First, add this above the Blow() function:

function IsPlayer(character)
	return Players:GetPlayerFromCharacter(character)
end

Then add this to the code I showed you before:

if IsPlayer(character) then -- pass in the character as a parameter and cancel the damage if it matches to a player in the game (this will be nil if it is an NPC so the sword will deal damage)
	return
end

as for working in R15, I assume you mean the animations are broke or something? in that case, you'll have to remake the animations using an R15 rig
