ok so i got rid of the error but it wont draw the number now, here's the new code:

//argument0 = global.invpos
//argument1 = object
//argument2 = weight of objects

var closest_obj;
closest_obj = 0;
if place_meeting(o_inv_back.x + global.inv_array[0,1],o_inv_back.y + global.inv_array[0,2],argument1)
{
    closest_obj = 1;
}
if place_meeting(o_inv_back.x + global.inv_array[1,1],o_inv_back.y + global.inv_array[1,2],argument1)
{
    closest_obj = 2;
}
if place_meeting(o_inv_back.x + global.inv_array[2,1],o_inv_back.y + global.inv_array[2,2],argument1)
{
    closest_obj = 3;
}
if argument0 > 0
{
    if (global.inv_array[closest_obj-1,0] > argument2)
    {
        global.inv_array[closest_obj-1,0] -= argument2;
        global.inv_array[closest_obj-1,3] += 1;
        draw_text(o_inv_back.x + global.inv_array[closest_obj-1,1] + 32,o_inv_back.y + global.inv_array[closest_obj-1,2],global.inv_array[closest_obj-1,3]);
    }
}
else
{
    instance_create(o_inv_back.x+global.inv_array[argument0,1],o_inv_back.y+global.inv_array[argument0,2],argument1);
    global.invnum += 1;
}

it should say "negative array index or index out of bounds", no?

Your probably trying to access an index that's out of bounds of your array.


Also:

closest_obj-1

if closest_obj is 0, then you will be accessing a negative array index.

exactly, so those lines i used to figure out the closest obj, first its not complete but should work, and that is where it is messing up.

nvm i figured it out, if a mod would close this topic that would be good.

You don't delete the sprite when you're done drawing it. You just let it be, and don't draw it. So get rid of all the parts in there about deleting the sprite, and you should be fine.

could you explain this a little more, what i want to do is draw a sprite when i press "i" and delete it when i press "escape".

yeah, I bet you have an object for the inventory as well, so you dont need to delete the sprite...

When an object is destroyed, all the sprites it was drawing are deleted. So dont bother.

Just have a central inventory object, have that spawn all of the slots, and when its destroyed destroy all the slots. Why do you need to draw a sprite in the first place?

because im not using an object for them.
