EOS Feature Request: Add PageManager.getPageIds method

[fapnip]

It would be nice to have a getPageIds method that would return an array of all page ids.

I really wanted a way to at the very least check if a page exists or not for use in re-usable code, so the game can dynamically adapt to the pages defined in the given tease.

So here it is:

Code: Select all

// Add a missing 'pages.contains(pageId)' method to EOS PageManager
// Allows checking if a given page exists or not
pages.contains || (pages.contains = function (pageId) {
  // Store the original state of the page, if any.
  // (pages.isEnabled will always return true for pages that don't exist)
  var origState = pages.isEnabled(pageId)
  // Disable the page (will not store disabled state for pages that don't exist)
  pages.disable(pageId)
  // If the page is now disabled, it exists.  Missing pages will always return true. 
  var hasPage = !pages.isEnabled(pageId)
  // If the page exists, restore its state to what it was when we got here
  if (hasPage && origState) pages.enable(pageId)
  // Return our result
  return hasPage
})

And here's a minified version:

Code: Select all

// Add a missing 'pages.contains(pageId)' method to EOS PageManager
// See: https://milovana.com/forum/viewtopic.php?p=288586#p288586
pages.contains||(pages.contains=function(a){var e=pages.isEnabled(a);pages.disable(a);var s=!pages.isEnabled(a);return s&&e&&pages.enable(a),s});

Add the above to the start of your init script. You will now be able to use: if(pages.contains('my-page-name')) ...

Doesn't completely solve this feature request, but covers many of the use cases for it.
