ds_stack_empty

With this function you can check the given DS stack to see if it is empty (returns true) or not (returns false).

 

Syntax:

ds_stack_empty(id);

Argument Description
id The id of the data structure to check.

Boolean

 

Example:

if (ai_count == 15) && (!ds_stack_empty(AI_stack))
    {
    ds_stack_clear(AI_stack);
    alarm[0] = room_speed;
