Not at the moment, but soon :)

Word Wars, Slime Volley, Fire Nano, and Shapeshifter are a few games using the API

Just finished up 2 tutorials for Clay.io & Construct 2:

API Integration

Publishing to Clay.io

Yep, it's on our todo list to integrate our Payments API into the Scirra plugin.

I updated the plugin again, it turns out it still wasn't working quite right when the game was minified (it only appeared to work correctly because it the unminified version was being stored in app cache, which clearing browser cache doesn't catch).

It should work properly for exporting and minifying now.

We take 20% of any revenue generated through Clay.io (both on sales of your game, and in game purchases using our payments API). If your game is completely free, our service is completely free.

Can you PM me what the URL is that keeps showing for you?

The payment API doesn't work with Facebook credits at the moment, but it's definitely on our todo list

1) There already is a way and documentation is under the "EXPRESSIONS" section under screenshots. So you would have an event with the Clay.io condition "screenshot taken" and action post to Facebook - then for the picture field, use the Clay.io expression Screenshot SRC"

2) I think it is possible, I've added that to my todo list

Sheepy I've updated the game settings page to make that more clear, thanks for pointing it out

— Hmm, yes it would seem I didn't upload the file to the correct spot - download again here

That's a very basic implementation of it. If you hold the space bar down, the score will go up, when you left click on the score, it will post it and show the leaderboard.

Let me know if you figure out what's going wrong!

1) As of right now you have to override our CSS on your page. Our CSS stylesheet is inserted after the first <script> tag, so as long as you have your CSS after the first <script> tag in index.html, all of our stuff should get overridden.

Chrome's dev tools/firebug will be your best friend for this, but the structure for achievements is:

.clay-achievement

.clay-achievement-header

.clay-achievement-content

    (if there's an icon for the achievement you'll have these as well)

    .clay-achievement-icon

    .clay-achievement-description

    (endif)

.clay-achievement-close

2) The payment API being integrated into the plugin is on the todo list. I've integrated "Show all achievements" and updated the plugin with it

3) Encryption isn't possible right now. I'm not familiar enough with Construct 2 to know if you can create a backend for your game. So long as you have a backend, you'll be able to. Perhaps there's a way to get it working well with the AJAX plugin, I'll have to take a look

4) Fixed (no need to update the plugin for this fix to work)
