    I added my own character skeletal mesh/rig and now all the equipment no longer applies to the character the right way. I'm not really sure how to go about fixing this since I've always used sockets to attach things and this system doesnt do that. The rig I'm using is a slightly modified version of the ue4 rig.

    I think this is a problem caused by the joint orientation.

    Thanks. This works.

    I need to iterate through the entire Inventory Item array so that I can send the item ids (and perhaps some other things such as item quality, condition, and so forth) through a socket to a server which will in turn relay the inventory to MySQL and back again when necessary.

    I had presumed that there would be a simple way to determine the number of items in the array without knowing anything about the array itself. I take it that this is not possible?

    If you have not modified the Equipment Slots this node will return 14 because the Equip slots are 0-13.

    The value reported by the length node, the tooltip of which says "Get the number of items in an array.", always shows zero for the Inventory Item Array in the editor.

    The inventory is working properly in game.

    I know that I can get a hack number by adding the number of Equipment slots to the number of backpack slots and use that as an iterator, but how can I programmatically derive the number of slots in the Inventory Item Array?

    Oh thanks!
    Am trying to figure out the error too. Here is exactly what I found.
    Location:InventoryManagerComponent>function>User Interface>Private>Inventory>AddInventorySlots.
    If I don't use the "Item Information" node, The error will be disappeared.
    I check a few times for "Inventory Layout(widget)\Inventory Slots(widget)". They are the same as your's.

    Help me out, please!
    I received your email I will try and figure out what you might have missed in the merge to cause this error this weekend. As I am out of town for a few more days on business. Perhaps trying to merge over again might be a good idea as it's possible something was missed.

    This is by design and if you look at games like world of warcraft and guild wars it has the same approach. You can get the number of equipmentslots from the enum so you aren't using a magic number like 14. this way also if you end up modifying your equipment slot amount the logic will automatically work with the new count.

    This is what also makes dayz type looting easy to do if you want as you can see on the demo NPC's loot window equipped items as well.

    Oh? Hmmmm.....
