Desc = [[
This hook is called when Cuberite receives a left-click packet from the {{cClientHandle|client}}. It
is called before any processing whatsoever is performed on the packet, meaning that hacked /
malicious clients may be trigerring this event very often and with unchecked parameters. Therefore
plugin authors are advised to use extreme caution with this callback.</p>
<p>
Plugins may refuse the default processing for the packet, causing Cuberite to behave as if the
packet has never arrived. This may, however, create inconsistencies in the client - the client may
think that they broke a block, while the server didn't process the breaking, etc. For this reason,
if a plugin refuses the processing, Cuberite sends the block specified in the packet back to the
client (as if placed anew), if the status code specified a block-break action. For other actions,
plugins must rectify the situation on their own.</p>
<p>
The client sends the left-click packet for several other occasions, such as dropping the held item
(Q keypress) or shooting an arrow. This is reflected in the Status code. Consult the
<a href="http://wiki.vg/Protocol#Player_Digging">protocol documentation</a> for details on the actions.

Returns = [[
If the function returns false or no value, Cuberite calls other plugins' callbacks and finally sends
the packet for further processing.</p>
<p>
If the function returns true, no other plugins are called, processing is halted. If the action was a
block dig, Cuberite sends the block specified in the coords back to the client. The packet is
dropped.
