MoreCoolers

Really simple and straightforward mod to be used with the Spoiled mod.

In the spoiled-common.toml file, just add the following:

 containerModifier = [
     "morecoolers:copper_cooler,0.6",
     "morecoolers:iron_cooler,0.4",
     "morecoolers:gold_cooler,0.2",
     "morecoolers:diamond_cooler,0.05"
]

In the above example, food placed in the copper_cooler will spoil at 60% the normal rate, iron 40%, gold 20%, and diamond 5%.

The config file for this mod allows you to add more storage rows but that's it. Also, don't change the rows after you've installed this mod. Determine how many rows you want first. You cannot change the recipe. Recipe is very expensive as it takes 7 blocks of the corresponding ore, a snow bucket in the middle, and a glass pane on the top middle. 

This mod was meant to be simple and used as a reward in the endgame to essentially keep you food from spoiling.

Please take note that this was made just for my family and I's survival modpack and will likely never receive any sort of update.

In case anyone uses this and wants to change the recipe, this works for CraftTweaker 14.0.40. Change the shaped recipe to whatever suits you:

// Removing existing recipes for coolers
craftingTable.remove(<item:morecoolers:copper_cooler>);
craftingTable.remove(<item:morecoolers:iron_cooler>);
craftingTable.remove(<item:morecoolers:gold_cooler>);
craftingTable.remove(<item:morecoolers:diamond_cooler>);
