So what should I have bought if I wanted to recive the spear and sword animations as well!
This is confusing me!
Take a deep breath and try to calm yourself. I know there are a lot of words and pictures on each page, so i put a brief explanation at the top to help you understand.
The Farmer Sprite System (the one you bought) is intended for cozy farming sim style games. It has a lot of non-combat animations and a lot of outfits and hairstyles. It's not made with combat in mind, but plenty of devs use the farming animations for combat by combining the weapon sprites from this asset.
The Character Base (the asset on this page, which you haven't yet purchased) is an older asset with more general utility. It has some farming animations and some combat animations. Including explicit support for sword & shield, spear, and bow. However, it doesn't have many outfit options, and limited non-combat animations.
You own the Farmer Sprite System, so you can compare it to the free sample for the Character Base (available for download on this page), which has the full sword and shield animations, and decide what you want to do. If you're desperate for the spears, then you can buy this pack. But I personally think the Farmer Sprite System has more to offer with its outfit and hairstyle variety.
