random item

[cozzy09]

guys can you tell me if I have the right idea about this script

set $@prize, rand(1,100);
if ( $@prize <= 5 ) {
getitem ???, 1;
   announce "Poring Catcher : We have a winner, "+.@name$+". - won a prize1",0;

}

if ( $@prize <= 1 ) {
getitem ???, 1; // Cool FB Hat
   announce "Poring Catcher : We have a winner, "+.@name$+". - won a prize2",0;

}

if ( $@prize <= 10 ) {
getitem ???, 1;
getitem ???, 1;
   announce "Poring Catcher : We have a winner, "+.@name$+". - won a prize3",0;
}

does this make it that if the random rolls to 5 which is <=5 also <= 10 will I get both items? or just the <= 5 item only?

prontera,155,180,5	script	test item reward#2	100,{
.@rand = rand( 17 + 33 + 50 ); // total 100
if ( .@rand < 17 ) { // /17/100 ... about 1/6 * 100%
	getitem 503, 1;
	getitem 504, 1;
	announce "Poring Catcher : We have a winner, "+ strcharinfo(0) +". - won a prize3",0;
}
else if ( .@rand < 33 ) { // 33/100 ... about 1/3 * 100%
	getitem 501, 1;
	announce "Poring Catcher : We have a winner, "+ strcharinfo(0) +". - won a prize2",0;
}
else { // the rest is 50/100, which is 1/2 * 100%
	getitem 502, 1; // Cool FB Hat
	announce "Poring Catcher : We have a winner, "+ strcharinfo(0) +". - won a prize1",0;
}
end;
}

if you want make it 100%, then make the variable total up to 100 ...

If you want to get only 1 item at once, use 'end;'

Otherwise, it will give you multiple items at once.

prontera,161,182,4 script test123 110,{
set .@prize, rand(1,100);
if ( .@prize <= 1 ) {
 getitem 502, 1; // Cool FB Hat
 announce "Poring Catcher : We have a winner, "+.@name$+". - won a prize1",0;
 end;
}

if ( .@prize <= 5 ) {
 getitem 501, 1;
 announce "Poring Catcher : We have a winner, "+.@name$+". - won a prize2",0;
 end;
}

if ( .@prize <= 10 ) {
 getitem 503, 1;
 getitem 504, 1;
 announce "Poring Catcher : We have a winner, "+.@name$+". - won a prize3",0;
}
end;
}

ok thanks alot

now the chance for item 1 = 1% then item 2 is 4% right? since its 2-5 only?

       getitem 503, 1;
       getitem 504, 1;
       announce "Poring Catcher : We have a winner, "+ strcharinfo(0) +". - won a prize3",0;
   }
   else if ( .@rand < 1+5 ) { // 5/16
       getitem 501, 1;

I'm a little bit confused about your code XD

if will give me a 1/16 % chance of getting the item and the else only will give me all the remaining chances but what about the else if? is it 2% or a total of 6% chance of getting the item?

[AnnieRuru]

its not by 100% percent, but per-total

1/16 chance get prize3

5/16 chance get prize2

10/16 chance get prize1

16 is the total of 1+5+10

[cozzy09]

yup but can't I just put 16 in there hahaha XD

[cozzy09]

ok thank you so much for enlightening me hahahaha
