Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthHackosaur 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
