Reads the value from the tail of the queue.



参数 描述
id The id of the data structure to read from.

返回: 实数或字符串


This function will only read the last value of the queue (that which is "at the tail"). It will not dequeue the value, meaning that it can still be read in the future by this function or the ds_queue_dequeue.


num = ds_queue_tail(control_queue);

The above code will read the value from the queue indexed in the variable "control_queue" and store the return value in the variable "num".
