R> a NPC that change "YPoints" to x1 Random Item [Solved]

[ItsFree]

Hi, rAthena Comunity yeah i know that this request can be maybe solve making a custom box (yep i know how do it) but the problem is that the custom box dont set the ammount :/ what i want is like a "gambler" or something like that i try to find some of them yeah i found some but got some errores or didnt work like i want... anyyway this is what i want:

The player change 1 point to a "try" the try can give you x1 red pot, x2 red pot, x10 red pot, x5 blue pot, x3 green pots.... etc in short words...

x1 point ==> X Item with Y Ammount.

Thx! if need more information tell me, also gonna edit trying to add examples what i wanted to help to have an idea~
 

is like this but maybe on "reverse" x1 point for a random item with X amount.

the "point" can be get it from other npc for "point" you can use cashpoints i guess is an example what i mean for "point" ><

MAP,X,Y,Z	script	GamblerNPC::spiritD	400,{

	if(#CASHPOINTS == 0){
		mes "You don't have enough points";
		close;
	}
	if(#CASHPOINTS > 0){
		mes "You have "+#CASHPOINTS+" cash points.";
		mes "One roll costs 1 cash point.";
		mes "Would you like to roll?";
		switch(select("No thanks:Yes please")){
		case 1:
			close;
		case 2:
			#CASHPOINTS--;		//subtract CASHPOINTS by 1
			.@winNum = rand(4);	//5 prizes to choose from (0-4)
			if(.@winNum == 0){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 1){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 2){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 3){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 4){ getitem <PRIZE_ID>,1; }
			else { debugmes "[GamblerNPC] "+strcharinfo(0)+" is a hacker!!"; }
			mes "Congrats!";
			close;
		}
	}
}

Fill in your own NPC coordinates and prizes

I can do this but:

The player change 1 point

What is the point? what should I take away from the player to give them a try?

[ItsFree]

the "point" can be get it from other npc for "point" you can use cashpoints i guess is an example what i mean for "point" ><

[ItsFree]

nice working now just 2 things:

1.- to add more is just add more...
 

			if(.@winNum == 5){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 6){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 7){ getitem <PRIZE_ID>,1; }
			if(.@winNum == 8){ getitem <PRIZE_ID>,1; }

just that or have to edit something else ¿?

2.- is there a way to add a "percent" about each item ¿? i mean to controll it and set all different % percent just like a custom box...

Thx! <3

you have it correct but there is one more thing to edit

			.@winNum = rand(4);	//5 prizes to choose from (0-4)

make sure the number is ONE LESS than the max amount of prizes so if you have 8 prizes the number inside the rand(#) will be 7 (because zero counts as one!)

 

the percent would involve some tricky math but it's possible... like you want prize#1 to be rare, prize#2 to be uncommon, and all the rest be common? I could do that but you would have to set up all your prizes and what percent you want them (and they should add up to be 100% otherwise im gonna dunk you )

its ok i even if is more work "for me" set 1 by 1... its ok i'll do it, what i want is "between more controlable the percents better" what i want is 
something like <prize_id>,#amount,<percent> if possible...

im sure there is a cleaner way to do this but this should work:

			.@winNum = rand(99);  //100
			if (.@winNum >= 0 && .@winNum <= 4) { getitem <PRIZE_ID>,1; } //5% chance
			if (.@winNum >= 5 && .@winNum <= 9) { getitem <PRIZE_ID>,1; } //5% chance
			if (.@winNum >= 10 && .@winNum <= 19) { getitem <PRIZE_ID>,1; } //10% chance
			if (.@winNum >= 20 && .@winNum <= 29) { getitem <PRIZE_ID>,1; } //10% chance
			if (.@winNum >= 30 && .@winNum <= 49) { getitem <PRIZE_ID>,1; } //20% chance
			if (.@winNum >= 50 && .@winNum <= 99) { getitem <PRIZE_ID>,1; } //50% chance
			else { debugmes "[GamblerNPC] "+strcharinfo(0)+" is a hacker!!"; }

Do you understand this example?

[ItsFree]

not really about how to know what should i put to "configure" the percent of each one yeah if i copy&paste im sure will work but dont understand how edit it xD

the npc would be something like this i guess

 

prontera,145,171,5	script	GamblerNPC::spiritD	112,{

	if(#CASHPOINTS == 0){
		mes "You don't have enough points";
		close;
	}
	if(#CASHPOINTS > 0){
		mes "You have "+#CASHPOINTS+" cash points.";
		mes "One roll costs 1 cash point.";
		mes "Would you like to roll?";
		switch(select("No thanks:Yes please")){
		case 1:
			close;
		case 2:
			#CASHPOINTS--;		//subtract CASHPOINTS by 1
			.@winNum = rand(99);  //100
			if (.@winNum >= 0 && .@winNum <= 4) { getitem <PRIZE_ID>,1; } //5% chance
			if (.@winNum >= 5 && .@winNum <= 9) { getitem <PRIZE_ID>,1; } //5% chance
			if (.@winNum >= 10 && .@winNum <= 19) { getitem <PRIZE_ID>,1; } //10% chance
			if (.@winNum >= 20 && .@winNum <= 29) { getitem <PRIZE_ID>,1; } //10% chance
			if (.@winNum >= 30 && .@winNum <= 49) { getitem <PRIZE_ID>,1; } //20% chance
			if (.@winNum >= 50 && .@winNum <= 99) { getitem <PRIZE_ID>,1; } //50% chance
			else { debugmes "[GamblerNPC] "+strcharinfo(0)+" is a hacker!!"; }
			mes "Congrats!";
			close;
		}
	}
}

yes that is correct. If you want to create a list of items with quantities as well as the percentage they should be rewarded, I can configure the logic for you.

[ItsFree]

yeah i understand that the only thing i dont understand is how to set the percents >< i guess is something about this

 

if (.@winNum >= 0 && .@winNum <= 4)

but i dont get it

https://www.mathsisfun.com/percentage.html

The script is saying if "winning Number" is greater than or equal to zero AND less than or equal to 4 (meaning 0-4) then you win a prize. Because there are 100 different numbers that are picked  randomly, therefore your chances to get numbers 0-4 is 5%

oh seeing on that perspective ok now i get it (yeah i know maths... sometimes i just thinks would be more hard but now i see not, ok now i get it, thx!
