+ Desc = [[
+ This hook is called when MCServer 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 MCServer 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, MCServer 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#0x0E">protocol documentation</a> for details on the actions.
