[Paid] Modified npc exchanger

prontera,196,141,4	script	POD	831,{

This script is working but I want to have a random rate of ITEM A to be exchanged to ITEM B. Numbers are 1, 2 or 3 maximum. So for example, the script returned 1 as the exchange rate, it would be like this: 1 ITEM A = 1 ITEM B. Then another session if the script returned 3 as the exchange rate, then 3 ITEM A = 1 ITEM B. The npc must show the random rate after the player has got the exchanged item.

 

I can pay to have something like this.

 

EXAMPLE: When the npc is clicked, it will ask how many ITEM A the player wants to exchange. So for example, if the player has 20 pcs ITEM A, and he puts all 20 to exchange and the script gave him 3 as the exchange rate, he will only receive 6 ITEM B and only 18 ITEM A will be decreased in his inventory. Meaning, 2 ITEM A will be left. 

 

Alternatively, if the player puts 20 to exchange and the script gave him 1 as the exchange rate, then he will receive 20 ITEM B all in all with no ITEM A left in his inventory.

Wow fantastic work. O.O Thanks Emistry! However, I noticed one small detail

getitem .@item_id[1],.@rate;

This code above is problematic. I exchanged 20 pcs ITEM A, but accdg to the screenshot below i only exchanged 18 pcs? Also, the rate that turned out is the same amount of ITEM B I got which is not supposed to be that way. Must be AMT OF ITEM A divided by EXCHANGE RATE, right? So for example I exchanged 20 pcs ITEM A, and the rate is 3, I must get 9pcs ITEM B and have 2 pcs ITEM A left in my inventory because the NPC will only get 18pcs ITEM A due to the rate. Pls check this screenshot below

 

I'm very ready to give a tip. I hope you can further help. TY

Ok I have modified it and now it's partially working, calculation is 100% correct with this code:

gonryun,172,132,5	script	Exchanger#rand_exchange	757,{
setarray .@item_id,
	111,	// item give
	222;	// item gain

mes "You currently have ^ff0000"+countitem(111)+"^000000 ITEM A.";
mes " ";
mes "^777777Exchange rate of ITEM A to ITEM B are random to 1-3.^000000";
if( select( "Exchange","Cancel" ) == 1 ){
	next;
	.@current_count = countitem( .@item_id[0] );
	if( .@current_count ){
		mes "How many "+getitemname( .@item_id[0] )+" do you want to exchange?";
		input .@amount,0,.@current_count;
		if( .@amount ){
			.@rate = rand( 1,3 ); 
			.@amount = ( .@amount );
			if( .@amount ){
				delitem .@item_id[0],( .@amount * .@rate );
				getitem .@item_id[1],( .@amount / .@rate );
				mes "[Randomized exchange rate for this session: ^777777"+.@rate+":1^000000]";
				mes "Exchanged "+( .@amount )+"x "+getitemname( .@item_id[0] )+" to "+( .@amount / .@rate )+"x "+getitemname( .@item_id[1] )+" .";

			}
		}
	}
	else{
		mes "You didnt have any "+getitemname( .@item_id[0] )+" to exchange.";
	}
} 
close;
}

But my problem is, I want to retain the left ITEM A in the inventory if the computation didn't equal to @amount. For example, I input 20pcs ITEM A, and the rate turned to be 3. So 20 divided by 3 = 6 pcs ITEM B to be added in the inventory, 6 x 3 = 18 pcs ITEM A to be removed in the inventory, and there will be 2pcs left of ITEM A needed to remain, on the other hand . So I guess the ff code must be edited?

				delitem .@item_id[0],( .@amount * .@rate );

[Emistry]

isnt that it's what you wanted ??

 

he puts all 20 to exchange and the script gave him 3 as the exchange rate, he will only receive 6 ITEM B and only 18 ITEM A will be decreased in his inventory.

 

in your case...there could be bugged.

example:

1. i got 100 apple
2. i exchange 99 apple to the npc ( rate 3 )
3. the npc delete 297 apple ( 3 x 99 )
4. but you only have 100 apple...the npc is bugged.

What i mean is when you put 20 pcs ITEM A in the npc, and the npc returned 3 as the rate, the player receives 6 pcs ITEM B right? But the npc takes ALL 20 pcs ITEM A instead of just 18 pcs. So 20 pcs item A gets deleted instead of just 18 pcs. Because 6 pcs item B is just equal to 18 pcs ITEM A, given that the player entered 20 pcs and the rate is 3.

 

I hope you got what Im trying to say. T_T

try

( CTRL + F5 refresh )

 

what you mention from above post is different from your first post, it's you who are confused with your own request.

Next time explain it more clearly.

[c2greentea]

Sorry Emistry. Let me try that.

 

Also, how to change .@rate = rand( 1,3 ); if I only want 2 and 4 as the choices?

[Emistry]

you can try

.@rate = ( 2 * rand(1,2) );

[c2greentea]

Emistry, what if the player enters an EVEN number with 2 and 4 as the only rate, the NPC will still get all ITEM A? For example, the player inputs 7 to be exchanged, and the script returned 2 as the rate, so obviously he'll just get 3 pcs ITEM B right? But the NPC will delete or get all 7 pcs ITEM A instead of just 6 pcs? How to fix it?

[Emistry]

the script delete item based on what number they have entered.

 

 

 

What i mean is when you put 20 pcs ITEM A in the npc, and the npc returned 3 as the rate, the player receives 6 pcs ITEM B right? But the npc takes ALL 20 pcs ITEM 

this is what you requested.

[c2greentea]

No Emistry, the "but" word is a contradicting statement. This is what I said:

What i mean is when you put 20 pcs ITEM A in the npc, and the npc returned 3 as the rate, the player receives 6 pcs ITEM B right? But the npc takes ALL 20 pcs ITEM A instead of just 18 pcs. So 20 pcs item A gets deleted instead of just 18 pcs. Because 6 pcs item B is just equal to 18 pcs ITEM A, given that the player entered 20 pcs and the rate is 3.

Can we still script it? Also, when the player enters 3 pcs ITEM A and the script returned 4 as the rate, the player gets nothing and the 3pcs ITEM A is deleted. Can we still do this?

[Emistry]

the  very first original version already did what you wanted.
