Check max 3 ids of array in the inventory !

[Angel]

Hello, ppl.

I need some help, i need a script that check a limit only 3 ids of array in inventory.

 

example:
 

setarray .@rental[0],990,991,992,993;

if you have in your inventory 990,991,992 every combination of 3 ids you cannot  get another item.

but if you have only 2 990,993 you can get other item.

 

i don't know how to check more of 3 ids in inventory, only  one 
 

getinventorylist;
    for(set .@i,0; .@i < @inventorylist_count; set .@i,.@i+1){
        if(@inventorylist_id[.@i] == .@rental > 2) {
              mes "Only 3 ids in inventory";
              close;
        }

Hope someone help me

You want to check if the user has fewer than three of an array of items?

 

setarray .@rental[0],990,991,992,993;
.@itmCnt = 0;
for (.@i = 0; .@i < getarraysize(.@rental); .@i++) {
    if (countitem(.@rental[.@i])) {
        .@itmCnt++;
    }
}

if (2 < .@itmCnt) {
    mes "You can have a maximum of two out of the following list:";
    for (.@i = 0; .@i < getarraysize(.@rental); .@i++) {
        mes "" + getitemname(.@rental[.@i]) + "";
    }
    close;
}

 

This should be what you're looking for, then.

getinventorylist;
	for(set .@i,0; .@i < @inventorylist_count; set .@i,.@i+1){
		for(set .@ii,0; .@ii < getarraysize(.@rental); set .@ii,.@ii + 1){
        		if(@inventorylist_id[.@i] == .@rental[.@ii]) {
        			set .@itemCount,.@itemCount + 1;
        		}
		}
	}
	if(.@itemCount >= 3) mes "Only 3ids in inventory";

I think that what you're looking for
