Hello. I noticed that chance for treasure maps by default is R99 in loot templates. I have a question, is it possible to use R100 or R150 for example? Will be it as 1 for 150 or how that random calculates?

Post: #2

the higher the number the harder to get...


,R2 = 50% chance

I though function R works only when less than 100, because it was R99 in script, but not R100

Thanks.

Your right Art, it stops at 99, but if you want to make an item rarer than 99, you would have to add a variance in your script.

At 99, theres a 1% chance of dropping the loot (i think?) so if you want it lower add this to your npc

ON=@DEATH
VAR.RAND=<EVAL {1 1000}>
IF (<VAR.RAND><=5) //0.5% Chance Loot Drop
NEWITEM=i_something_rare
ACT.BOUNCE
RETURN 0
ENDIF

It does add a variance on R100 but it seems to only make it more common than R99, which i dont understand...

sorry, i never knew 99 was the limit...

Mmmm... I think, there are no limit here. I will test this tomorrow.

There is no limit, I use a lot R1000 without any problem. In fact If you use only R, a R1000 is executed in his place.

Note that R2 goes from 0 to 1, R99 goes from 0 to 98, R100 goes from 0 to 99, and R1000, from 0 to 999.
There is always one less number that you put in the random. If you want a random who begins at other number different of zero, use:

R1,10 to numbers from 1 to 10
R5,10 to numbers from 5 to 10

using vars is actually a bad idea, use locals instead:

ON=@DEATH
LOCAL.RAND=<EVAL {1 1000}>
IF (<LOCAL.RAND><=5) //0.5% Chance Loot Drop
SERV.NEWITEM i_something_rare
NEW.CONT <SRC.FINDLAYER.21.UID>
RETURN 0
ENDIF

Rx is ok to use i guess, but u have better control if u use ur own algorithm, please correct me if i am wrong.

LOCAL.RAND=<EVAL {1 1000}>
IF (<LOCAL.RAND><=5) //0.5% Chance Loot Drop

has the same results as

IF (<R1,1000><=5) //0.5% Chance Loot Drop

which is the same as

IF (<R><=5) //0.5% Chance Loot Drop

...except that in these versions, there less for the server to do since there is less script to parse, no allocation of memory for the temporary local string variable, no evaluation of the random {}, no assignment of the resulting integer to the string value, no re-evaluation of the string back to an integer in the if statement...

To be fair however, this all takes place in microseconds.inside a @Death trigger that does not get called all that often. :-)

Hm

So, if (<r> <= 5) is same as R200 or better? And have anyone tested, is item=i_test,R200 working if R more than 99 ?
