示例1: check_enough_materials
bool requirements::check_enough_materials( const item_comp& comp, const inventory& crafting_inv ) const
{
if( comp.available != a_true ) {
return false;
}
const itype *it = item_controller->find_template( comp.type );
const tool_comp *tq = find_by_type( tools, comp.type );
if( tq != nullptr ) {
// The very same item type is also needed as tool!
// Use charges of it, or use it by count?
const int tc = tq->count < 0 ? std::abs( tq->count ) : 1;
// Check for components + tool count. Check item amount (excludes
// pseudo items) and tool amount (includes pseudo items)
// Imagine: required = 1 welder (component) + 1 welder (tool),
// available = 1 welder (real item), 1 welding rig (creates
// a pseudo welder item). has_components(welder,2) returns false
// as there is only one real welder available, but has_tools(welder,2)
// returns true.
// Keep in mind that both requirements (tool+component) are checked
// before this. That assures that one real item is actually available,
// two welding rigs (and no real welder) would make this component
// non-available even before this function is called.
// Only ammo and (some) food is counted by charges, both are unlikely
// to appear as tool, but it's possible /-:
bool has_comps;
if( it->count_by_charges() && comp.count > 0 ) {

// tools applies.
