Struct BreakBlockEvent 

pub struct BreakBlockEvent<'a> {
    pub pos: [i32; 3],
    pub state: BlockState,
    pub exp_to_drop: &'a mut Option<u32>,
    pub cancelled: bool,
}

What Hooks::break_block is told. Each field is that hook’s argument of the same name, described in the hook’s doc.

Fields

pos: [i32; 3]

state: BlockState

exp_to_drop: &'a mut Option<u32>

cancelled: bool

Whether the event is cancelled: by the game or an earlier listener, or by this one setting it. Only a listener that receives cancelled events (#[listener(receive_cancelled)]) sees true, and setting it back to false lets the game’s behaviour run.
