Falling Block

Falling blocks are entities which are used to allow sand and gravel to smoothly fall down.

Appearance
Falling blocks appear as opaque cubes using the textures of the block it represents.

These blocks appear as 1x1x1 cubes, which is slightly larger than their collision box.

Behaviour
Falling blocks accelerate downwards at a rate of approximately 0.8m/s² until colliding with a solid surface. Upon landing, the entity will despawn and check whether the nearest block space is vacant. If so, it will place the block it represents in that block space.

Notably, this means partial, non-replaceable blocks such as slabs can cause falling blocks to despawn without placing their respective block.

Since falling blocks are entities, their motion can be redirected by external forces.
