About this Mod

Hackosaur Mod

ok so this is my minecraft mod for 1.21.1. got some items that do stuff

you can glide around,
mine ores and sometimes get extra drops,
and shoot lightning at things. pretty cool i guess


building it

the jar file ends up here after you build:
build/libs/Hackosaur-1.0.0.jar

if you wanna build and run it yourself:

# build it
./gradlew.bat clean build

# run the game with the mod
./gradlew.bat runClient

# or run a server idk
./gradlew.bat runServer

installing

you need fabric loader for 1.21.1 from https://fabricmc.net

also grab fabric api and put it in your mods folder

then just drop the Hackosaur jar in .minecraft/mods/ and you're good

what's in it

hackclub banner

/give @s hackosaur:hackclub_banner

red and white banner thing, you can only have 1 at a time for some reason

glitch pickaxe

/give @s hackosaur:glitch_pickaxe

purple pickaxe, diamond tier. has a 25% chance to dupe ore drops which is kinda broken but whatever

it prints a bunch of debug stuff to console when you mine

flag of flight

/give @s hackosaur:flag_of_flight

hold it while falling and you glide down slowly

also you don't take fall damage which is nice

lightning staff

/give @s hackosaur:lightning_staff

right click and it shoots lightning where you're looking (up to 50 blocks away)

has 64 uses and a 3 second cooldown

craft it with: diamond + 2 gold ingots + 2 sticks

be careful not to blow up your house lol

debug stuff

there's a ton of console spam because i wanted to see what was happening:

  • when items get registered
  • every time you mine something
  • lightning strikes
  • gliding

you can probably remove that stuff if it's annoying

issues

textures are kinda basic but they work

no sounds yet

lightning staff might be too op idk

what works

  • java 21 ✓
  • minecraft 1.21.1 ✓
  • all items have textures and can be crafted ✓
  • glitch pickaxe ore duplication ✓
  • flag of flight gliding ✓
  • lightning staff ✓

testing it

just run ./gradlew.bat runClient and mess around

if you change something rebuild with ./gradlew.bat build

that's it i guess, have fun
