How to override physics?

[TC1061]

How to override physics in Cuberite? Is there any hook to do this? For example:

Code:

IsFallingEnabled=true
function OnBlockFalling(Block,x,y,z)
  if IsFallingEnabled then
    return false -- Allow block to fall
  else
    return true -- Prevent block from falling
  end
end

function EntityPhysicsTick(Entity,dx,dy,dz)
  -- Do something
  return true -- Do not call any other plugins
end
