This lets you mod things server-side only (ie clients don’t need to install mods). And do so without having to compile or do much other than have a text editor. There are some limits (eg you can’t introduce new textures or models) but it’s still a lot of fun.
Mischief I’ve been up to with it:
- Make cows and horses shearable (drops leather, reverts them to baby form temporarily) by intercepting PlayerUseEntityEvent
- Disable fall damage near a particular mysterious tall tower and play a splash noise instead, by intercepting BeforeLivingEntityDamageEvent
- Add mysterious sometimes-teleporters to two sets of identical ruins (one near spawn). My friends hated this, the rules to get it to work were too arbitrary. I felt like a 90’s adventure game developer.
- Add an /easydifficulty command (sets a player’s max health higher), because some people on the server just wanted to farm, build and chill.
- A deathchest mod, where the inventory is stored in an invisible minecraft:interaction entity stretched over a sign with a head on top. The advantage of this over chests is that all the items can be restored to their original inventory slots (including cursed armor xD) as I can store arbitrary data.
- Add a /crush <player> command, which informs the target that you have a crush on them and gives them a free rose.
I feel torn. I also want to troll my friends. A bad UX is what they deserve, especially that friend who works in the printer industry and complains all the time about how badly documented many minecraft mods are.
One of the ways to get my portal to work was to hold exactly 7 items in your current hand. This is also how I want Firefox’s new UI to work.
