Java mod listed for Minecraft 1.20–1.21. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This mod adds 4 new blocks to the game:
slow, medium and fast Speedblocks
and 1 Jump Block!
Speedblocks push players, mobs and items to the direction the arrow is pointing at, while Jump Block throws them up!
It can be really useful when you want to transport animals or when you want to transport items to hopper -> chest.
The blocks also change textures while something is touching them!
You can turn off that just by going to Mods -> SpeedBlocks -> Config (for Forge and NeoForge)
Or by editing config/speedblock/speedblock.json file (for Fabric)
