Scripts for the QBox framework. QBox is a maintained fork of QBCore rebuilt around the ox resource family, so it uses qbx_core with ox_lib, ox_inventory and ox_target rather than the original qb- equivalents.
That difference is the thing to check. A QBCore script is not automatically a QBox script: it will call qb-core exports and qb-inventory item functions that QBox does not provide in the same shape. Some resources ship both code paths, many do not. Confirm a listing names QBox or qbx_core explicitly rather than inferring it from a QBCore label. Because the framework is younger and moves faster, also check when the resource was last updated — QBox resources age more quickly against their core than ESX resources do.
