Windows Collisions - Check if No Objects are Touching the Active Object

[AppDude27]

Goal:
Check to see if no objects are touching the active object.

Issue:
My code scripts are not working. I've looked into the collisions section on yoyo games documentation, but everything I've tried doesn't work.

Failed attempts:
if (position_empty(obj_ActiveInventoryItem.x, obj_ActiveInventoryItem.y))
if (place_meeting(x,y, all)
if (place_meeting(x,y,obj_ActiveInventoryItem)

Suggestions would be appreciated.

It sounds like you're trying to make an inventory system, similar to Diablo or WoW, where the items take up one or more slots in a bag.

If that's the case, I'd recommend using a ds_list, ds_map or ds_grid instead.

That's actually exactly what I'm doing, minus the slots and grid system. I'm trying to make my game more "touch screen friendly" by seeing how far I could go without the grid system. This collision thing is just giving me a headache.
Is there really no way to check if all instances in the room are touching a single instance?

In pseudo code:

//Default: nothing is equipped
if (any instance in the room is not touching the active item box)
{
Set the variable activeItemEquipped = false;
Set sprite of inventory box to show an empty box;
}
else if (a specific instance in the room IS touching the active item box)
{
Set the variable of activeItemEquipped = true;
Set the sprite of the inventory box to show that specific item
}

and so on...

I would just use code to figure out which cell the mouse (finger) was over, and directly referencethe corresponding ds_ entry.

Update:

I actually solved this issue by flipping my logic. I'll explain in pseudo code:

if (a specific instance in the room IS touching the active item box)
{
Set the variable of activeItemEquipped = true;
Set the sprite of the inventory box to show that specific item
}
else
{
Set the variable activeItemEquipped = false;
Set sprite of inventory box to show an empty box;
}

Thanks for helping!
