Dimensional Gravity [1.20.5 - 1.20.6]

IMPORTANT: This data pack requires version 1.20.5 - 1.20.6. The 1.21+ version can be found here.

What does this pack do?
This is just a small data pack that I quickly threw together today. As the name suggests, it changes the gravity attribute (and other gravity-related attributes) of entities in different dimensions.

How does it change the attributes?
In the Overworld, all attributes are normal.
In the Nether, gravity and fall damage are very slightly increased.
In the End, gravity and fall damage are drastically decreased, and step height is raised to 1 block.

Is this pack compatible with non-vanilla dimensions?
No, but you can manually add them to the pack if you want. Note that the attribute modifier value system is a little weird.

Is this pack compatible with other attribute-changing effects?
As far as I am aware, yes. This pack uses attribute modifiers rather than changing the base attributes directly, so all attribute-based effects from other mods or data packs should stack with the effects from this pack.
