Okay I have made decent progress, however I am running into an issue using GT Tools. From what I understand they each have an item tag to identify them rather than an actual id. I have created a script to cheapen the costs of lower tier plates and it works. However whenever a player on the server uses the recipe I get the message " Warning subitems- do not have damaged states" I have tried to append the script with ".withTag({{}})" and ".withTag({{*}})" but those just break the script.
Here is the working script :
recipes.addShaped(<Railcraft:part.plate:1>, [[<gregtech:gt.metatool.01:12>.transformDamage(5),null,null],[<gregtech:gt.metaitem.01:11305>,null,null]]);
