OK, it is now changed to a simple RCL == 8 check for edge cases when there is only one possible structure per room. Here is function’s source code:
exports.checkStructureAgainstController = function(object, roomObjects, roomController) {
<span class="hljs-keyword">if</span>(!<span class="hljs-keyword">object</span>.user) {
<span class="hljs-keyword">return</span> <span class="hljs-keyword">true</span>;
}
<span class="hljs-keyword">if</span>(!roomController || roomController.level < <span class="hljs-number">1</span> || <span class="hljs-keyword">object</span>.user && roomController.user != <span class="hljs-keyword">object</span>.user) {
<span class="hljs-keyword">return</span> <span class="hljs-keyword">false</span>;
}
<span class="hljs-keyword">if</span>(C.CONTROLLER_STRUCTURES[<span class="hljs-keyword">object</span>.<span class="hljs-keyword">type</span>][<span class="hljs-number">8</span>] == <span class="hljs-number">1</span>) {
<span class="hljs-keyword">return</span> C.CONTROLLER_STRUCTURES[<span class="hljs-keyword">object</span>.<span class="hljs-keyword">type</span>][roomController.level] != <span class="hljs-number">0</span>;
}
<span class="hljs-keyword">var</span> objects = _.filter(roomObjects, {<span class="hljs-keyword">type</span>: <span class="hljs-keyword">object</span>.<span class="hljs-keyword">type</span>, user: <span class="hljs-keyword">object</span>.user});
<span class="hljs-keyword">if</span>(objects.length > C.CONTROLLER_STRUCTURES[<span class="hljs-keyword">object</span>.<span class="hljs-keyword">type</span>][roomController.level]) {
objects.sort(exports.comparatorDistance(roomController));
objects = _.take(objects, C.CONTROLLER_STRUCTURES[<span class="hljs-keyword">object</span>.<span class="hljs-keyword">type</span>][roomController.level]);
<span class="hljs-keyword">if</span>(!_.contains(objects, <span class="hljs-keyword">object</span>)) {
<span class="hljs-keyword">return</span> <span class="hljs-keyword">false</span>;
}
}
<span class="hljs-keyword">return</span> <span class="hljs-keyword">true</span>;
};
