About this Mod
There is no mod that does this so far,at least I haven't seen any,
it may not be very useful but it seems to me that it is useful,
at least for those who have read the documentation WHICH ONLY TAKES A FEW MINUTES TO READ, today I present Jcraft (Json Craft) is a mod/library to be able to use the fabric API in Json configuration files, I would consider it a bit useless but I didn't know what to do so this occurred to me, you can add blocks and items with very little programming!, except the texture, for that use Texture Packs, I will soon solve that, and soon there will also be improvements!
How to use
jcraft creates a folder in the game directory called 'jcraft', inside this folder there are two other 'blocks' and 'items', inside these folders the json are added, it doesn't matter the name, the important thing is the structure, in the case For the items, the important thing is to add the values name and namespace, you can also add the settings and more, an example of json item would be:
{
"name": "myItem",
"namespace": "myMod",
"settings":{
"fireproof": true
}
}
with the value fireproof: true makes it fire resistant, while name and namespace configure the basic values, such as the item name and the namespace (such as the mod name)
How to add a block
Something similar happens with the blocks, these have the name and the namespace, but apart from that they also contain the item value that adds the item of the block in addition to the block itself, in settings the easiest thing to configure is the parent , An example:
{
"name": "myBlock",
"namespace": "myMod",
"settings":{
"parent": "BEDROCK"
}
}
The parent does what it inherits the configuration of the block that has already been configured, it is important to put it in capitals as in this case the BEDROCK
