 Unfortunately there's like three layers of indirection before we can actually start adding some advancements, but we'll go one layer at a time. First things first, in the ''DataGeneration'' file we created earlier, add the following: Unfortunately there's like three layers of indirection before we can actually start adding some advancements, but we'll go one layer at a time.

   * This name is only ever used by ''requirements'' (another property we can add to advancements) which make it so that before an advancement activates, the ''requirements'' (other advancements) need to be fulfilled first. In other words, it mostly doesn't matter what name you give the criterion.   * This name is only ever used by ''requirements'' (another property we can add to advancements) which make it so that before an advancement activates, the ''requirements'' (other advancements) need to be fulfilled first.

-The second argument is the criterion. In our example we use the ''InventoryChangedCriterion'' and we pass it the item we want it to trigger for ''Items.DIRT''. But there are many criterions. The Minecraft Wiki has them listed as "[[https://minecraft.fandom.com/wiki/Advancement/JSON_format|List of triggers]]". But the better reference to use is the Minecraft source itself. (If you haven't generated the source yet, read [[tutorial:setup#generating_minecraft_sources|here]].) You can take a look at the ''net.minecraft.advancement.criterion'' folder where they are all located and see what's already available.+The second argument is the criterion.

 If you run your game now (changing that fake function to a simple ''true'' so it compiles), when you log into a world, you should be granted the jumping jack advancement, but because we are using the server join event here to do this, it gives it to you before you load in, which is why you don't get a toast message. If you open up the advancements page in the escape menu, you'll see it was in fact granted. If you run your game now (changing that fake function to a simple ''true'' so it compiles), when you log into a world, you should be granted the jumping jack advancement, but because we are using the server join event here to do this, it gives it to you before you load in, which is why you don't get a toast message.
