Tactical Fishing

Your fish should be handled automatically as long as you follow the minecraft naming style ( "[modid]:[fish]", "[modid]:[fish]_bucket" ), I also included a "[modid]:raw_[fish]" as a fallback in case you are still using old naming.
However there might be cases where you would not want something to be auto-gen'd for your item. Fish recipes won't be created if the following data path already exists in any directory "data.tactical_fishing.recipes.inbuilt.fishing_[modid]_[fish]_bucket.json".

Your rods should also be handled automatically as long as they extend "net.minecraft.item.FishingRodItem", and it should work as long as your fishing hook projectile uses the "net.minecraftforge.event.entity.player.ItemFishedEvent" Forge Event.
However if your rod is a custom item for whichever reason you can include it in the "tactical_fishing:fishing_rods" item tag.

If you wish to create new fishing recipes for your mod here is the syntax:

{
    "type": "tactical_fishing:fishing",
    "group": "", //This is optional like in default recipes; if you want to make this recipe count for the "Advanced Tactics" advancement add "tactical_fishing:fish_buckets" here.
    "rod": {}, //Ingredient syntax, this specifies the rod needed for the recipe, if you want any rod to count use the "tactical_fishing:fishing_rods" tag
    "ingredient": {}, //Ingredient syntax, this specifies what else you need to hold for the recipe
    "catch": {}, //Ingredient syntax, this specifies what needs to be caught to finalize the recipe
    "result": {} //ItemStack syntax, this specifies what is created from the recipe
}

Here is a template from the auto-gen'd recipes

{
    "type": "tactical_fishing:fishing",
    "group": "tactical_fishing:fish_buckets",
    "rod": {
         "tag": "tactical_fishing:fishing_rods"
    },
    "ingredient": {
         "item": "minecraft:water_bucket"
    },
    "catch": {
         "item": "minecraft:cod"
    },
    "result": {
         "item": "minecraft:cod_bucket"
    },
    "conditions": [
        {
              "type": "forge:mod_loaded",
              "modid": "minecraft"
         }
    ]
}

You can suppress certain features via the config, like disabling the auto-gen'd fish recipes altogether.
