Falling Block Inverted Gravity

[MaxAnimator]

Hello there,

so I tried making a falling block that falls up. So I made a new entity that extends FallingBlockEntity and I overwrited a method in the constructor to change the motion of the entity. I tried changing values to their negative equivalent and multipliying them by -1 but none worked. 

package com.maxandcarl.inan.entities;

import net.minecraft.block.BlockState;
import net.minecraft.entity.EntityType;
import net.minecraft.entity.item.FallingBlockEntity;
import net.minecraft.world.World;

public class EndGravelBlockEntity extends FallingBlockEntity{

	public EndGravelBlockEntity(World worldIn, double x, double y, double z, BlockState fallingBlockState) {
		super(worldIn, x, y, z, fallingBlockState);
		this.setPosition(x, y + (double)((1.0F - this.getHeight()) /2.0F) * -1, z);
	}
	
	public EndGravelBlockEntity(EntityType<? extends FallingBlockEntity> type, World worldIn)
	{
		super(type, worldIn);
	}
	
}

Help please. Is gravity linked directly to this function for falling blocks or is it something else that applies to every entity that I have to change?

Gravity is a myth for the basic Entity class. Give it some velocity and it'll start moving in the direction you want. Probably should use Entity::setMotion and some Vector3d::add. You also might want to override the tick method.

Also you may need to disable gravity with Entity#setNoGravity, so you could ignore stock gravity applied to FallingBlockEntity,

Hello again, after a long time I got back onto this issue. I tried many things, and currently I found this function "this.setMotion(this.getMotion().add(0.0D, 0.08D, 0.0D));".

But it still doesnt work, the entity just doesnt move and stays in air. Yes I tried changing the value to see if it was counter balanced by another use of this function in the code, but still nothing.

package com.maxandcarl.inan.entities;

import net.minecraft.entity.EntityType;
import net.minecraft.entity.item.FallingBlockEntity;
import net.minecraft.world.World;

public class EndGravelBlockEntity extends FallingBlockEntity{
	
	@Override
	public void tick()
	{
		this.setMotion(this.getMotion().add(0.0D, 0.08D, 0.0D));
	}
	
	public EndGravelBlockEntity(EntityType<? extends FallingBlockEntity> type, World worldIn)
	{
		super(type, worldIn);
	}
	
}

You should add a call to super.tick() in your tick method (or at least a call to this.move()).
