Here's an idea. What about adding in throwing weapons, such as spears and throwing axes?

what do I do if the recipes for ammo do not spawn?

Great mod dude ,thank you .But there is something keeps bothering me ,NPCs wont collect pebbles on the ground even after I set them to collect .

I think this is steel ball trying to spawn on the body :)
Let me check the patch.

Thank you ! I think I know what was causing the error, and I just uploaded a patch. Not sure if it's fixed, but if you try it again let me know

Crash when shooting bunny in the winter, from Modern Slingshot with steel ball:

Exception (v215): NullReferenceException: Object reference not set to an instance of an object TileObject.CreateProp (PropPrototype proto) (at C:/Survivalist2/Assets/Scripts/Terrain/TileObject.cs:35)

Just a quick feedback. Please name slingshots differently?

A must have for any survival nut! :)
