    if (event.entity.isPlayer()) {
        let damage = event.damage
        let player = event.source.player
        let entity = event.entity;
        let server = event.server;
        let health = entity.health;
        let username = entity.getGameProfile().getName();
        server.runCommandSilent(`execute as ${username} run say ${damage} ${health}`);
        event.cancel()
    }
})
