<div id="dev_page_content"><p>Telegram supports sending <a href="https://telegram.org/blog/folders#and-one-more-thing">animated dice</a> emojis.<br>
This is implemented by using the dice constructors: </p>

2022-05-14 00:37:40 +02:00
<p>On startup, clients should fetch <a href="/api/config#client-configuration">app configuration using help.getAppConfig</a>.<br>
2022-11-15 00:55:37 +01:00
Then, for each dice emoji contained in the <a href="/api/config#emojies-send-dice"><code>emojies_send_dice</code> field</a>, clients should fetch the dice emoji stickerset by calling the <a href="/method/messages.getStickerSet">messages.getStickerSet</a> method, providing the properly populated <a href="/constructor/inputStickerSetDice">inputStickerSetDice</a> to the <code>stickerset</code> field.<br>
2022-05-14 00:37:40 +02:00
The returned stickerset will contain a set of animated stickers, one for each of the dice outcomes, plus a first looping sticker that should be shown as preview to the user before actually sending the dice. </p>
<p>If a user attempts to send a single emoji from the ones specified in <code>emojies_send_dice</code>, the dice should be sent using <a href="/method/messages.sendMedia">messages.sendMedia</a>, providing the dice emoji to the <code>emoticon</code> field. </p>
<p>Incoming dice stickers will be received as a <a href="/constructor/messageMediaDice">messageMediaDice</a> constructor, along with a randomly generated server-side value, ranging from 1 to the maximum allowed value for this type of dice.<br>
Clients should display the correct dice animated sticker for the specified value: since dice values start from 1, and the first animated sticker in dice stickerset is the preview, <code>value</code> can be used to directly index the <code>documents</code> sticker array from the animated stickerset. </p>
2022-11-15 00:55:37 +01:00
<p>The <a href="/api/config#emojies-send-dice-success"><code>emojies_send_dice_success</code> configuration parameter</a> contains more info about dice emojis other than the basic <img class="emoji" src="//telegram.org/img/emoji/40/F09F8EB2.png" width="20" height="20" alt="🎲" />: </p>

},
"\ud83c\udfc0": {
"value": 5,
"frame_start": 110
}
}</code></pre>
<p>For each of the dice emojis, a maximum "winning" value is specified, along with the frame number at which to show the fireworks <img class="emoji" src="//telegram.org/img/emoji/40/F09F8E86.png" width="20" height="20" alt="🎆" />.<br>
2022-11-15 00:55:37 +01:00
Please note that dice animated stickers should loop only once, right after being sent/received <strong>for the first time</strong>; clicking on the dice sticker should bring up a popup, inviting the user to send a new dice of the same type. </p>
<h3><a class="anchor" href="#slot-machine" id="slot-machine" name="slot-machine"><i class="anchor-icon"></i></a>Slot machine</h3>
<p>Slot machine <img class="emoji" src="//telegram.org/img/emoji/40/F09F8EB0.png" width="20" height="20" alt="🎰" /> dice stickers are implemented a bit differently: the <code>value</code> isn't used to directly index the stickers array, but is instead used as follows. </p>
<p>The <code>value</code> is composed of three 2-bit values, each indicating the animated sticker to show in the three slots, incremented by one. </p>
<p>The <code>stickers</code> array is composed as follows:</p>
<ul>
<li>0 =&gt; Slot machine background</li>
<li>1 =&gt; Slot machine winning background, to show after a winning spin</li>
<li>2 =&gt; Slot machine frame&amp;handle to play once at the beginning</li>
<li>3 =&gt; Left slot winning 7</li>
<li>4..7 =&gt; Left slot non-winning options</li>
<li>8 =&gt; Left slot spinning animation</li>
<li>9 =&gt; Center slot winning 7</li>
<li>10..13 =&gt; Center slot non-winning options</li>
<li>14 =&gt; Center slot spinning animation</li>
<li>15 =&gt; Right slot winning 7</li>
<li>16..19 =&gt; Right slot non-winning options</li>
<li>20 =&gt; Right slot spinning animation</li>
</ul>
<p>How to play the animation (all involved stickers are to be directly overlaid on top of each other, no special placing is required): </p>
<ul>
<li>Freeze single-frame background (<code>0</code>)</li>
<li>Play handle animation (<code>2</code>) once</li>
<li>Play the three spinning slots animations (<code>8</code>, <code>14</code>, <code>20</code>) once</li>
<li>Play the three slot animations once, chosen as follows:<ul>
<li>If we're in a winning <code>value == 64</code>:<ul>
<li>Left slot: choose <code>3</code></li>
<li>Center slot: choose <code>9</code></li>
<li>Right slot: choose <code>15</code></li>
</ul>
</li>
<li>Otherwise, considering <code>map := [1, 2, 3, 0]</code>:<ul>
<li>Left slot: choose <code>4 + map[(value-1) &amp; 3]</code></li>
<li>Center slot: choose <code>10 + map[((value-1) &gt;&gt; 2) &amp; 3]</code></li>
<li>Right slot: choose <code>16 + map[((value-1) &gt;&gt; 4) &amp; 3]</code></li>
</ul>
</li>
</ul>
</li>
<li>If we're in a winning <code>value=64</code>, replace the background (<code>0</code>) with <code>1</code>.</li>
</ul>
