This is very simple control that allow to set/get numeric value from inner html of div/span, and provides animation on from/to value.

Dependency

Don't forget to add ebg/counter as a dependency:

   // in your game js
   define([
   "dojo","dojo/_base/declare",
   "ebg/core/gamegui",
   "ebg/counter"    /// <==== HERE],

Setup a counter

var counter = new ebg.counter();
counter.create(targetId);

Where targetId either string or dom element, which already exists in the template, which will be used to display the counter value. For example:

  <span id="my_counter"></span>

In reality you will have a counter per player, so probably want to cretae a counter per player, in this case target Id can be 'hand_size_player_' + player_id and you create it in the loop for all players and store as class member. See example below on how to inject per-player sections.

Functions on counter

create(target)

associate counter with existing target dom element

getValue()

return current value

incValue(by);

increment value by "by" and animate from previous value

setValue(value);

set value, no animation

toValue(value);

set value with animation

disable()

display - instead. Note it just changes display value once, it does not actually disables it, i.e. if you set it again, it will be shown again

Players panels

Adding stuff to player's panel

First, create a new JS template string in your template (tpl) file.

From the Gomoku example:

var jstpl_player_board = '\<div class="cp_board">\
    <div id="stoneicon_p${id}" class="gmk_stoneicon gmk_stoneicon_${color}"></div><span id="stonecount_p${id}">0</span>\
</div>';

Then, add this piece of code in the setup function of your JS file to add this template to each player panel:

            // Setting up player boards
            this.stone_counters={};
            for( var player_id in gamedatas.players )   {
                var player = gamedatas.players[player_id];
                         
                // Setting up players boards if needed
                var player_board_div = $('player_board_'+player_id);
                dojo.place( this.format_block('jstpl_player_board', player ), player_board_div );

                // create counter per player
                this.stone_counters[player_id]=new ebg.counter();
                this.stone_counters[player_id].create('stoneicon_p'+player_id);
            }

Often, you have to distinguish between the current player and other players. In this case, create another JS template (ex: jstpl_otherplayer_board) and use it where "player_id" is different than "this.player_id".
