Data Structures

Hi, I am trying to create a ds_list and have been trying to create a test program to see if I have got it right but it doesnt seem to work. I understand the concept but dont think I have structured the program correctly. The code is written in an invisible controller object.

Here is my code, any help would be appreciated. Thank you.

CREATE
list = ds_list_create();
listmax = 10;

STEP
if (keyboard_check_pressed(vk_space))
{
if (ds_list_size(list) < listmax)
{
ds_list_add(list,"Item");
}

if (ds_list_size(list) > listmax)
{
show_message("Max Reached")
}
}

Try => rather than just >

Your if loop only puts 10 items in the list, so there will never be 11, so the message will never show.

Otherwise, everything looks correct to me.

NEOSHADE: Thank you for the reply, I got an error with => so I used >= instead and it worked fine.

Oh, yeah, sorry. I always get those backwards.

{
    if (ds_list_size(list) < listmax)
    {
    ds_list_add(list,"Item");
    }
    else
    {
    show_message("Max Reached")
    }
}
