I want to know how would I smelt an item when broken by a specific modded pickaxe so like if I wanted to mine iron with the pickaxe it would drop an iron ingot instead of iron or and so one and so forth. 

Are you looking for a mod that has an auto-smelting feature or are you trying to make an auto-smelting feature? If it's the former, lots of mods have auto-smelting features: Tinkers' Construct, Cyclic, and plenty of other mods. If it's the latter however, I can't help you.

It is the latter I am looking for like how to make the twilight forest fiery pickaxe with the Auto-Smelt enchantment which whenever you mine any ore it gives the smelted item. If if the ore is moded.

I'm thinking you could modify the vanilla loot tables to match for a tool that has your custom enchantment, and if they do, return the smelted item (maybe you can do so that for every block (or ore to optimize), you check if it is an ingredient to a smelting recipe, and modify that block's loot table to match?)

Can I please have an example of this.

 

And also your method works for only vanilla items I want to make it so that any item that is a ore that can be smelted can work with this pickaxe.

it should work with any smeltable ore, since you'd be checking for smelting recipes, and any modded smelting recipe is registered in the same place you'd be checking for.

it would actually work for any block that can be smelted, so breaking sand with the pick would return glass. if that's not the desired behaviour, you can check if the block has the ore tag

Ok I see what going for, but as I already told I am new at modding and there aren't many tutorials for 1.16 modding. So could I please have an example of what you are describing?

check diesieben answer, he points to the GlobalLootModifier documentation, and tells you how to get the smelting recipe output for that item. additionally you may want to check if the block is an ore, for that you could use Tags.Blocks.ORES.contains()

 

Yeah I literally wrote the code for autosmelt already.

Things've changed a bit, but it was one of the "someone is going to want this, so my system better support it" test mod examples.

Use a GlobalLootModifier. In there check if any of the dropped stacks is smeltable. To do this, you need an inventory (you can just use new Inventory(1)) and put the stack into it. Then call RecipeManager#getRecipe(IRecipeType.SMELTING, <inventory>, <world>). If that returns something, use IRecipe#getRecipeOutput to get the output (remember to copy it) and replace the dropped stack with it.

how to replace the dropped stack ?

It's almost like I wrote all the code you need for you.
