Show / Hide Tooltips

[RavingWanderer]

Two questions which are relevant to this discussion:
1. How does one interrogate (get the current value of) the BGA-supplied "Display tooltips" preference?
2. How is one notified that it has changed? (It doesn't force a refresh.)

Answers to these questions should be documented someplace (in the options file doc, game.js doc, or other place?)

It's stored with the other preferences, number 200. Read with: this.prefs[200]

Regarding updates, the framework doesn't provide a callback, so you have to add your own. Something like this can be done during the setup, connected to each of the dropdowns (remember there are two spots with the same dropdowns -- the Options tab below the game, and the top-right corner):

Code: Select all

      var _this = this;
      var updatePreference = function (e) {
        var match = e.target.id.match(/^preference_[cf]ontrol_(\d+)$/)
        if (!match) {
          return;
        }
        var pref = +match[1];
        var prefValue = +e.target.value;
        _this.prefs[pref].value = prefValue;
        if (pref == 123) {
          // do something here if you care about pref #123 changing
        }
      };

      dojo.query('.preference_control').connect('onchange', updatePreference);

Thanks for detailing this.
