First, to help with lag and help with limiting crafting conditions, we can take this repeated section of code and make it into it’s own function: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/4/2/421aba1a81188e16952bf0e3ef9e413428896da3.png) This way, we can simplify the ‘Collect item’ and ‘Lose item’ functions into this: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/f/d/fdcb88bb909a055741fe373bfc52929eacfb78c8.png) So we can easily modify the craft function to check for the number of materials: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/b/5/b540f3e2c275b57f62b6af6a75e18a071065d663.png) [Here’s the link to add this function!](https://arcade.makecode.com/S75244-41495-71459-91829) The lag issue is a harder one to fix, but [there are helpful tips in this thread](https://forum.makecode.com/t/how-to-make-arcade-run-faster/20897)! --- _[View the full topic](https://forum.makecode.com/t/inventory-problem/39473)._
