Click action
Click actions are called whenever a player interacts with a block or other part of the world (through a mouse click).
There are hundreds of different causes of a click action, such as interacting with a crafting table, opening a chest or opening a door/trapdoor.
Syntax
You can use the click action query in one of these two ways:
action:click
a:click
Uses
I've personally found the click
action very useful when looking up which
player clicked the trapdoor above another player's ender pearl stasis chamber.
There are probably far more uses than this. You can also see when players clicked buttons, flipped levers, etc.
Example lookup
/co lookup action:click ...
Example lookup: only oak trapdoors
/co lookup action:click include:oak_trapdoor ...
