Windows DS not existing? How the...

[FredyJabe]

Hi everyone,

I have a pretty annoying problem, it always says that my DS doesn't exists.

This is a piece of my create event

name = "?";
model = 0;
weapon = 0;
thrusters = 0;
wings = 0;
armor = 0;
shield = 0;
battery = 0;
genrator = 0;
cargo = 0;
shipButt = 0;

shipColor = c_white;
thrustColor = c_orange;

sector = "Unknown Sector";

canShoot = true;

maxHull = 100;
hull = maxHull;
maxEnergy = 1;
energy = maxEnergy;
maxShield = 1;
shield = maxShield;
cargo = ds_list_create();
maxCargo = 1;

ds_list_add(cargo,0,1,2,3,2,2);

speedPrevious = 0;
maxSpeed = 2;
acceleration = 0.25;
deceleration = 0.05;
rotation = 2;

image_speed = 0;

// Menustuff
drag = -1;
lastMX = 0;
lastMY = 0;

for (var i=0;i<4;i++)
{
    menuX[i] = 256;
    menuY[i] = 256;
}
menuW[0] = 0;
menuH[0] = 0;
menuW[1] = 372;
menuH[1] = 256;
menuW[2] = 0;
menuH[2] = 0;
menuW[3] = 0;
menuH[4] = 0;

itemNav = 1;

// Position stuff
lastX = x;
lastY = y;

flames = ds_queue_create();
alarm[1] = room_speed / 2;

And this is where the error is hapenning, in the draw event

/// Menu window drawing

for(var i=0;i<4;i++)
{
    if (menu[i])
    {
        switch(i)
        {
            case 0: // Main
                //
                break;
            case 1: // Inventory
                var xx = view_xview+menuX[i];
                var yy = view_yview+menuY[i];
               
                draw_set_color(c_white);
                draw_set_alpha(1);
                draw_sprite(sprHUDinventory,0,xx,yy);
               
                var activeItem = database_item_get(itemNav);
                draw_sprite(ds_map_find_value(activeItem,"ItemSprite"),0,xx+12,yy+12);
               
                draw_set_font(ftItemNavActive);
                draw_set_valign(fa_top);
                draw_set_halign(fa_left);
                draw_set_colour(c_black);
                draw_text(xx+136,yy+37,ds_map_find_value(activeItem,"Name"));
               
                var activeItemB, activeItemC;
                if (itemNav == 0) activeItemB = database_item_get(ds_list_find_value(cargo,ds_list_size(cargo)-1));
                else activeItemB = database_item_get(itemNav-1);
                if (itemNav == ds_list_size(cargo)) activeItemC = database_item_get(ds_list_find_value(cargo,1));
                else activeItemC = database_item_get(itemNav+1);
               
                draw_set_font(ftItemNav);
                draw_set_alpha(0.5);
                draw_text(xx+124,yy+12,ds_map_find_value(activeItemB,"Name"));
                draw_text(xx+124,yy+74,ds_map_find_value(activeItemC,"Name"));
               
                break;
            case 2: // Equiped
                //
                break;
            case 3: // Options
                //
                break;
            default:
                break;
        }
    }
}

at the itemNav part.

If anyone could look through my code, it's been almost an hour that Im stuck at this exact point.

Thanks,
Jabe

Hi and welcome to the GMC!

I can't directly find what's wrong with your code.
Could you provide more information?
Like, what's the object information (text that appears when clicking on "object information" when editing an object) of the object executing the code above?
And what's the entire error message you're getting?
And is there any other code in your project destroying DS structures?
