+
+Digging a node
+--------------
+
+Preconditions are a node somewhere in the map.
+This node is pointable, has a selection box and can be dug by the hand or the tool the player is wielding.
+The player has interact priv and the tool has a tool range that the node can be pointed.
+The node is not stuck somewhere the player can't point it.
+
+*   First look at the node, it becomes pointed\_thing.
+
+    Note that on android the node is pointed without looking (referring to the cross position) at it.
+
+*   Then LMB is pressed down while holding an item which does not have on\_use.
+
+    If LMB wasn't released before, a click happens, which causes a punch event.
+
+    -   The client send a punch event (client->interact(4, pointed), see game.cpp:3657 (28.02.2017)).
+
+    -   On server side the punch event is passed to mods, see on\_punch and the deprecated register\_on\_punchnode.
+
+    Then the client sends the digging start event to the server (interact(0, pointed), game.cpp:3948).
+
+    -   The server uses this information for anticheat measurements.
+
+*   Now continue looking at the node, i.e. keep pointing it, and hold down LMB.
+
+    Periodically client-side: Crack animation is updated, digging particles are spawned (if not disabled in the settings) and the node dig sound is played.
+
+    -   The dig sound is either the "dig" field in the "sounds" table in the nodedef
+
+    -   or, if it's not present, the client uses the sound "default\_dig\_${groupname}" (file name extension omitted here), where $groupname is one of the groups the node has, see (game.cpp:4001), and gain is set to 0.5.
+
+    -   The default\_dig\_ thing should be banned from source code in my opinion.
+
+*   Some time later, when the digging time elapsed,
+
+    the client sends a digging completion event to the server (interact(2, pointed), game.cpp:4018),
+
+    the node disappears client-side,
+
+    more particles are spawned (if enabled) and
+
+    the dug sound is played.
+
+*   Now the server recieves the digging completion event.
+
+    Anticheat probably, e.g due to lag, thinks the player dug the node too fast.
+
+    -   dug\_too\_fast cheat is passed to mods, see register\_on\_cheat, and digging aborts.
+
+    If the nodedef has a can\_dig function, it's executed and probably stops the digging.
+
+    The on\_dig function in the nodedef is called now.
+
+    -   The default on\_dig function problably removes the node:
+
+        -   The on\_destruct is executed, air is set and after\_destruct is executed.
+
+    -   And probably (the same probably as before) it then calls the after\_dig\_node function in the nodedef if present.
