Need help on scripting with chances

[Bisuke]

I'm currently coding my own mining system, I just want to ask on how to make an npc that gives a random loot with different chances?

 

Example

 

Stone 55%

Iron Ore 35%

Iron 25%

Elunium 3%

Oridecon 5%

Gold 1%

 

If i click my npc randomly it'll generate a drop that is based on the rates.

 

My code is something like this

 

 

set @chance,rand(1,200);

 

if(@chance == 1) getitem 998,1;

if(@chance == 2) getitem 998,1;

if(@chance == 3) getitem 998,1;

if(@chance == 4) getitem 998,1;

if(@chance == 5) getitem 998,1;

if(@chance == 6) getitem 998,1;

if(@chance == 7) getitem 998,1;

if(@chance == 8) getitem 998,1;

 

I assigned items on every numbers which made my code very hard to modify.

 

Can someone help me make the code more efficient and easy to modify, like adding new drops with new rates?

 

Thanks!

.@i = rand(100); // = 100%

if( .@i < 1 ) setarray .@Item[0],969,1;
else if( .@i < 5 ) setarray .@Item[0],984,1;
else if( .@i < 3 ) setarray .@Item[0],985,1;
else if( .@i < 25 ) setarray .@Item[0],998,1;

else if( .@i < 35 ) setarray .@Item[0],1002,1;

else if( .@i < 55 ) setarray .@Item[0],7049,1;

 

how to change the value of the reward?

 

.@Item[0],7049,5; // Gives 5 Stones
