This function will dequeue the head value off of the DS queue, removing it from the queue and returning the value to be stored in a variable. If the queue is empty then the function will return the constant undefined, otherwise it will return the value contained in the queue.
ds_queue_dequeue(id);
| Argument | Type | Description |
|---|---|---|
| id | DS Queue | The id of the queue to dequeue from. |
Any (Data type value stored in the queue) or undefined
if (!ds_queue_empty(move_queue))
{
var xx = ds_queue_dequeue(move_queue);
var yy = ds_queue_dequeue(move_queue);
move_towards_point(xx, yy, 4);
}
The above code checks the DS queue indexed in the variable "move_queue" to see if it is empty, and if it is not, it then dequeues the two values from the head of the queue and use them to set a direction for movement.
