Useful Snippets
<lsl>string InventoryName(string name, integer type) {//finds an item in a case insensitive fashion of the given type and returns its true name.
integer a = llGetInventoryType(name); if(!~a)//a == INVENTORY_NONE {//it should be noted that INVENTORY_NONE == INVENTORY_ALL == -1; which is why '!~a' works. string lc_name = llToLower(name); a = llGetInventoryNumber(type); while(a) {//(a = ~-a) is equivalent to --a, but runs faster. if(llToLower(name = llGetInventoryName(type, a = ~-a)) == lc_name) {//we found a match ^_^ return name; } } } else if((a == type) ^ (!~type))//return name, as long as a == type or type == INVENTORY_ALL {//we already know that a != INVENTORY_NONE, but just in case we use xor instead of or. return name; } return "";//no match ~_~
}
integer InventoryExists(string name, integer type) {//only included to show how this type of check could be done if the value of 'type' is not constant and could be INVENTORY_ALL.
return (llGetInventoryType(name) == type) ^ (!~type);
}//Since INVENTORY_ALL == INVENTORY_NONE, the extra part on the end is required to invert the result.</lsl>
