About this project
What does Fluid Physics [Forge] add?
Fluid Physics
This mod blends together vanilla fluid mechanics with something a little more realistic plus some small additions. Fluids flowing horizontally will not be affected by this mod. Fluids flowing down will take the source with them. This is intentionally not a realistic fluid simulation in order to not break too much of the vanilla gameplay. If you want something more realistic look in the "Similar mods" section down below.
There is also a Fabric version
Features
- Fluid source blocks can flow down
- Removes infinite water sources (Can still be created by placing Spring blocks next to fluid sources)
- Pistons can pump fluids
- Spring blocks generate under naturally generated springs and prevent them from flowing down
- Rain refills lakes and oceans (similar to infinite water sources in vanilla)
- Works with vanilla clients (you have to set the config option spring/block to a vanilla block like 'mossy_cobblestone')
Requirements
- Minecraft Forge
- Scalable Cat's Force
- MixinBootstrap (only required on 1.15.2)
Screenshots

Videos
Known issues
- Under some circumstances fluids can stop flowing (This is why in the video I have the glass block slowing down the water flowing into the sandstone tank)
- There were issues reported when using this mod on 1.16.5 together with ForgeEndertech and Optifine or GraalVM. Please upgrade to Optifine G8 or use another JVM.
