Hello there!

In my new Mod i tried to create an custom craftingtable(in my case the welding table) with own recipes. I used a outdated tutorial(because i cant find a new one :/) and ran into some errors.

In the new versions of Minecraft is no 'CraftingManager.getInstance' and i can't figure out how to do the RecipeHandler. I already created the GUI but don't know if it works.
 

package boyx.rsreboot.handler.recipe;
