[1.12.2] Items Lag When Applying Motion

[unassigned]

Hello, I have a tile that 'sucks' in nearby items, however, the motion of the items are super choppy, and seemed off-sycned. Is this a networking issue? If so how would I fix this?

 

and here is the code applying the motion:

Spoiler

        List<EntityItem> nearbyItems = this.world.getEntitiesWithinAABB(EntityItem.class, new AxisAlignedBB(
                this.getPos().getX()-10, this.getPos().getY()-10, this.getPos().getZ()-10,
                this.getPos().getX()+10, this.getPos().getY()+10, this.getPos().getZ()+10
        ));
        if(nearbyItems.size() <= 0) return;

        for(EntityItem item : nearbyItems){
            double moveFactor = 0.035d;
            item.motionX += (this.getPos().getX() - item.getPosition().getX()) * moveFactor;
            item.motionY += (this.getPos().getY() - item.getPosition().getY()) * moveFactor;
            item.motionZ += (this.getPos().getZ() - item.getPosition().getZ()) * moveFactor;
            item.move(MoverType.SELF, item.motionX, item.motionY, item.motionZ);

        }

Don't call Entity#move, since the item is going to move on it's own each tick based on the motion values it has.Your movement is choppy because the item is moved twice per tick.

Apart from that I don't know if there are solutions to the position desync that occurs, especially when collisions happen.
