How do i make a block, that rotates the gravity

[Drachenbauer]

Hello

 

i have seen a mod, that has a block, that rotates the gravitx direction towards it.

It´s called a "gravity-core-block"

If the player is near it´s side, the player-model rotates horizontal with the feet to the block and if not creative-mode-flying, the payer is pulled to the block by a gravity effect.

If under the block, the same effect appears upside doen.

Maybe the same happens with entities.

 

How can i code this effect?

 

An how can i make an option, that changes the strength of gravity (reduced gravity = jumping higher and falling slower, negative gravity = hovering up and hanging under the ceiling like a helium filled balloon)?

Figure out what the other mod does. Minecraft does not have a global concept of "gravity." Instead each entity type handles its own gravity (and rendering!) separately.
