question about proper way of using arrays

[THPO]

Hi guys wanted to learn how to use array since I'm always using variables and it would take me some time to list everything there.

I wanted to use an array for my Quests and I wanted to use 2 set of array 1 for the Items needed and 1 for it's Quantity.

 

as you can see below I wanted them to countitem first then if it's true they will be deleted. else end;

 

example:

setarray .@ItemReq[0], 501, 502, 503, 504;
setarray .@ItemQty[0], 5, 10, 15, 20;

if(countitem(.@ItemReq[0]) >= .@ItemQty[0] || (.@ItemReq[1]) >= .@ItemQty[1] || (.@ItemReq[2]) >= .@ItemQty[2] || (.@ItemReq[3]) >= .@ItemQty[3] ) {
delitem .@ItemReq[0],.@ItemQty[0];
delitem .@ItemReq[1],.@ItemQty[1];
delitem .@ItemReq[2],.@ItemQty[2];
delitem .@ItemReq[3],.@ItemQty[3];
mes "Deleted all items .";
close;
} else { end; }

 

I'm really new to scripting and arrays.

appreciate any help you would mention

anyone can help me make it work and much easier?

something like this.

prontera,155,181,5	script	Sample#array	757,{
// loop + check item
for( .@i = 0; .@i < .item_size; .@i++ )
	if( countitem( .item[.@i] ) < .amount[.@i] ){
		mes "You need "+.amount[.@i]+"x "+getitemname( .item[.@i] );
		close;
	}

// loop again to delete item
for( .@i = 0; .@i < .item_size; .@i++ )
	delitem .item[.@i],.amount[.@i];

// done, get item
getitem 607;
mes "Done.";
close;

OnInit:
	// initialize items
	setarray .item,501,502,503,504,505;
	setarray .amount,1,2,3,4,5;
	.item_size = getarraysize( .item );
	end;
}

Thanks for your moment Mr. Emistry for taking a look at my thread but can I ask

what does this mean:

for( .@i = 0; .@i < .item_size; .@i++ )

especially the .@i

[Emistry]

loop .. variable ....

loop .. variable ....

http://en.wikipedia.org/wiki/For_loop

I need to read that ,

 

and here if I wanted do display all the items need:

how should i make it should I add someting like .item[.@i+1]

so all items needed will appear: 

You still need :

1x Red Potion

2x Orange Potion

3x Yellow Potion

4x White Potion etc..

mes "You still need "+.amount[.@i]+"x "+getitemname( .item[.@i] );
