Progression Mod allows you to control how a player can interact with the world, or the things they can craft, at the basic level. At the more involved level, it allows you to build and design tech trees, where a player cannot complete something until, something else is done. Be this action crafting an item, or collecting drops or more. You can also reward them for completing specific tasks, instead of restricting what they can do, if you so desire. Progression would also allow you to build class systems, restricting what certain groups of players can do, or give them abilities based upon their class. You could for example, forbid a group of people from ever being able to craft a furnace. While another group can build furnaces, but they walk much slower. This is just a basic overview of the things you can do with progression. With it’s requirements, conditions and results, you can create many more different systems than I have listed here, making it a very powerful tool for modpack makers.
There are two ways to access the editor. You must be in creative to edit. You can either right click a vanilla book, or type the command /progression edit. Please keep in mind when editing, that in order to test properly you are going to want to switch back to survival. You can always craft items, when you are in creative, which is why you should test in survival. To reset player data just use the command /progression reset. Tree Editor View
