ds_queue_head

Reads the value from the head of the queue.

Syntax:

GML Code Example

ds_queue_head(id);


Argument Description
id The id of the data structure to read from.


Returns: Real or String


Description

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


Example:

GML Code Example

num = ds_queue_head(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".
