Do you need to make the sword an object to kill enemies?

I am trying to make this game right now and it will take more time if I have make another function, or object.

See atan example.

You add a point to the end of the sword.

You add swinging the sword.

You add collision detection of the point with the sprite.

You add testing of the button press responsible for swinging the sword.

You have everything you need.

Thanks man. I hope this works. (it should) I know you help a lot. thank you. :)
